Although more and more researches have shown that edge-based information is more important than surface-based information in object recognition, it remains unclear whether edge-based features play a more crucial role than surface-based features in category learning. To address this issue, a modified prototype distortion task was adopted in the present study, in which each category was defined by a rule or similarity about either the edge-based features (i.e., contours or shapes) or the corresponding surface-based features (i.e., color (...) and textures). The results of Experiments 1 and 2 showed that when the category was defined by a rule, the performance was significantly better in the edge-based condition than in the surface-based condition in the testing phase, and increasing defined dimensions enhanced rather than reduced performance in the edge-based condition but not in the surface-based condition. The results of Experiment 3 showed that when each category was defined by similarity, there was also a larger learning effect when the category was defined by edge-based dimensions than by surface-based dimensions in the testing phase. The current study is the first to provide convergent evidence that the edge-based information matters more than surface-based information in incidental category learning. (shrink)

What role does experience play in the development of face recognition? A growing body of evidence indicates that newborn brains need slowly changing visual experiences to develop accurate visual recognition abilities. All of the work supporting this “slowness constraint” on visual development comes from studies testing basic‐level object recognition. Here, we present the results of controlled‐rearing experiments that provide evidence for a slowness constraint on the development of face recognition, a prototypical subordinate‐level object recognition task. We found that (1) (...) newborn chicks can rapidly develop view‐invariant face recognition and (2) the development of this ability relies on experience with slowly moving faces. When chicks were reared with quickly moving faces, they built distorted face representations that largely lacked invariance to viewpoint changes, effectively “breaking” their face recognition abilities. These results provide causal evidence that slowly changing visual experiences play a critical role in the development of face recognition, akin to basic‐level object recognition. Thus, face recognition is not a hardwired property of vision but is learned rapidly as the visual system adapts to the temporal structure of the animal's visual environment. (shrink)

In the present paper, we shall discuss the notion of prototype and show its benefits. First, we shall argue that the prototypes of common-sense concepts are necessary for making prompt and reliable categorisations and inferences. However, the features constituting the prototype of a particular concept are neither necessary nor sufficient conditions for determining category membership; in this sense, the prototype might lead to conclusions regarded as wrong from a theoretical perspective. That being said, the prototype remains (...) essential to handling most ordinary situations and helps us to perform important cognitive tasks. To exemplify this point, we shall focus on disease concepts. Our analysis concludes that the prototypical conception of disease is needed to make important inferences from a practical and clinical point of view. Moreover, it can still be compatible with a classical definition of disease, given in terms of necessary and sufficient conditions. In the first section, we shall compare the notion of stereotype, as it has been introduced in philosophy of language by Hilary Putnam, with the notion of prototype, as it has been developed in the cognitive sciences. In the second section, we shall discuss the general role of prototypical information in cognition and stress its centrality. In the third section, we shall apply our previous discussion to the specific case of medical concepts, before briefly summarising our conclusions in section four. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Global Healing and Reconciliation:The Gift and Task of Religion, a Buddhist-Christian PerspectivePeter C. Phan"No peace among nations without peace among the religions. No peace among the religions without dialogue between the religions. No dialogue between the religions without investigation of the foundation of the religions." Hans Küng's oft-quoted dictum proves even more apposite in the current international situation. Whether or not the September 11, 2001, tragedy and its (...) aftermath can be accounted for in religious terms, there has been a widespread perception that they were part of the conflict between Islam and the West and that this "clash of civilizations" has deep roots in different religious worldviews.Hindsight now shows us that "smart bombs" and armies do not and cannot resolve political problems in Afghanistan and Iraq or spread democracy in the world no matter how one judges the morality of these wars. The question then arises whether there are other ways and means to achieve world peace and reconciliation, to bring about healing among nations, and whether religions can be counted among these. More specifically, if religions can be harnessed to this task, which elements of the "foundation of the religions"—to use Hans Küng's words—need to be investigated in the dialogue among religions in order to bring about reconciliation among religions that in turns leads to reconciliation among nations?This essay explores how Buddhists and Christians can together serve the cause of peace and reconciliation among nations. I will first reflect on the nature, strategies, and spirituality of reconciliation. Next, I consider how the Buddha's and Jesus' teachings on justice, forgiveness, and reconciliation can contribute to global healing. To show the transformative power of these teachings, I conclude with some reflections on how the followers of the Buddha and Jesus can work together for world peace and global healing.Global Healing and Reconciliation: Strategies and SpiritualityAt first sight it seems preposterous and hypocritical to speak of global healing and reconciliation as the gift and task of religion. A brief glance at the history of global [End Page 89] warfare will persuade us of the sad fact that, in the words of Charles Kimball, "more wars have been waged, more people killed, and these days more evil perpetrated in the name of religion than by any other institutional force in human history."1 One is reminded of Jesus' injunction that we must first take the log out of our own eyes before attempting to take the speck out of our neighbor's (Matthew 7:5). Yet, religion is arguably the most powerful and effective institutional force for peace and reconciliation. To see how religion can bring this gift of peace to the world and achieve this task of global healing, a brief consideration of the nature and process of reconciliation is helpful.Etymologically, reconciliation means to cause two estranged persons or groups to meet each other again (re-, again + concilium, meeting). By extension, it means to resolve a dispute and to re-establish friendship and harmony, or, at a minimum, peaceful coexistence between opposed individuals or groups.2Reconciliation is both a process and a state of affairs. As process, it sets into motion a complex of agencies and strategies that cannot be used as a universally applicable recipe but requires appropriate tailoring to diverse contexts.3 The process includes certain intermediate stages as conditions of possibility for achieving the desired result. As a personal and sociopolitical state of affairs, reconciliation is an ever-fragile and elusive reality. Ultimately, because of human propensities toward violence and domination, total reconciliation and perfect peace is not achievable by human efforts but is hoped and prayed for as an eschatological gift bestowed by God or as a transcendent blessing beyond this world. This fact does not of course diminish our responsibility to bring about global healing by means of all the resources available, religious and otherwise.What Reconciliation Is NotIn our work for reconciliation it is essential to ascertain what it is not. In a helpful study on reconciliation Catholic theologian Robert Schreiter distinguishes three concepts that are allied to reconciliation but can distort its true sense. The first... (shrink)

This paper investigates whether an abstract linguistic construction shows the kind of prototype effects characteristic of non-linguistic categories, in both adults and young children. Adapting the prototype-plus-distortion methodology of Franks and Bransford (1971), we found that whereas adults were lured toward false-positive recognition of sentences with prototypical transitive semantics, young children showed no such effect. We examined two main implications of the results. First, it adds a novel data point to a growing body of research in cognitive (...) linguistics and construction grammar that shows abstract linguistic categories can behave in similar ways to non-linguistic categories, for example, by showing graded membership of a category. Thus, the findings lend psychological validity to the existing cross-linguistic evidence for prototypical transitive semantics. Second, we discuss a possible explanation for the fact that prototypical sentences were processed differently in adults and children, namely, that children’s transitive semantic network is not as interconnected or cognitively coherent as adults’.

The aim of this paper is to reconcile two claims that have long been thought to be incompatible: that we compositionally determine the meaning of complex expressions from the meaning of their parts, and that prototypes are components of the meaning of lexical terms such as fish, red, and gun. Hypotheses and are independently plausible, but most researchers think that reconciling them is a difficult, if not hopeless task. In particular, most linguists and philosophers agree that is not negotiable; (...) so they tend to reject. Recently, there have been some attempts to reconcile these claims, but they all adopt an implausibly weak notion of compositionality. Furthermore, parties to this debate tend to fall into a problematic way of individuating prototypes that is too externalistic. In contrast, I propose that we can reconcile and if we adopt, instead, an internalist and pluralist conception of prototypes and a context-sensitive but strong notion of compositionality. I argue that each of this proposals is independently plausible, and that, when taken together, provide the basis for a satisfactory account of prototype compositionality. (shrink)

Ethics consultation has become an integral part of the fabric of U.S. health care delivery. This article summarizes the second edition of the Core Competencies for Health Care Ethics Consultation report of the American Society for Bioethics and Humanities. The core knowledge and skills competencies identified in the first edition of Core Competencies have been adopted by various ethics consultation services and education programs, providing evidence of their endorsement as health care ethics consultation (HCEC) standards. This revised report was prompted (...) by thinking in the field that has evolved since the original report. Patients, family members, and health care providers who encounter ethical questions or concerns that ethics consultants could help address deserve access to efficient, effective, and accountable HCEC services. All individuals providing such services should be held to the standards of competence and quality described in the revised report. (shrink)

This article demonstrates the potential of using hierarchical Bayesian methods to relate models and data in the cognitive sciences. This is done using a worked example that considers an existing model of category representation, the Varying Abstraction Model (VAM), which attempts to infer the representations people use from their behavior in category learning tasks. The VAM allows for a wide variety of category representations to be inferred, but this article shows how a hierarchical Bayesian analysis can provide a unifying explanation (...) of the representational possibilities using 2 parameters. One parameter controls the emphasis on abstraction in category representations, and the other controls the emphasis on similarity. Using 30 previously published data sets, this work shows how inferences about these parameters, and about the category representations they generate, can be used to evaluate data in terms of the ongoing exemplar versus prototype and similarity versus rules debates in the literature. Using this concrete example, this article emphasizes the advantages of hierarchical Bayesian models in converting model selection problems to parameter estimation problems, and providing one way of specifying theoretically based priors for competing models.

Perception of time is susceptible to distortions; among other factors, it has been suggested that the perceived duration of a stimulus is affected by the observer’s expectations. It has been hypothesized that the duration of an oddball stimulus is overestimated because it is unexpected, whereas repeated stimuli have a shorter perceived duration because they are expected. However, recent findings suggest instead that fulfilled expectations about a stimulus elicit an increase in perceived duration, and that the oddball effect occurs because the (...) oddball is a target stimulus, not because it is unexpected. Therefore, it has been suggested that top-down attention is sometimes sufficient to explain this effect, and sometimes only necessary, with an additional contribution from saliency. However, how the expectedness of a target stimulus and its salient features affect its perceived duration is still an open question. In the present study, participants’ expectations about and the saliency of target stimuli were orthogonally manipulated with stimuli presented on a short (Experiment 1) or long (Experiment 2) temporal scale. Four repetitive standard stimuli preceded each target stimulus in a task in which participants judged whether the target was longer or shorter in duration than the standards. Engagement of top-down attention to target stimuli increased their perceived duration to the same extent irrespective of their expectedness. A small but significant additional contribution to this effect from the saliency of target stimuli was dependent on the temporal scale of stimulus presentation. In Experiment 1, saliency only significantly increased perceived duration in the case of expected target stimuli. In contrast, in Experiment 2, saliency exerted a significant effect on the overestimation elicited by unexpected target stimuli, but the contribution of this variable was eliminated in the case of expected target stimuli. These findings point to top-down attention as the primary cognitive mechanism underlying the perceptual extraction and processing of task-relevant information, which may be strongly correlated with perceived duration. Furthermore, the scalar properties of timing were observed, favoring the pacemaker-accumulator model of timing as the underlying timing mechanism. (shrink)

The purpose. Critical social philosophy of education strives to provide a radical critique of existing models of education in the so-called Western models of democracy, creating progressive alternative models. In this context, the proposed integrative metatheory, which is based on classical and modern sources, concepts, aims for a comprehensive understanding and reconstruction of the phenomenon of education. One of the main tasks in the sphere of education’s democratization today, therefore, is to bring to education the results of restructuring and democratization (...) of the society, to reflect changes in conditions of life and thinking, experience and transformation of subjectivity in the context of the technological revolution and globalization. Methodology. The critical social theory, which developed in the framework of contemporary neo-Marxism, indicates the need for a thorough analysis of society, however, unlike other theoretical concepts and research programs in order to analyze not a fixation and a statement of the existing social givens. On the contrary, critical analysis of society involves the identification of existing antagonistic, alienating factors that distort public communication.The subject of social analysis is the whole sphere of human and non-human nature, which interacts a person depend on it, the whole system of relations between society and nature, society and man, which is covered by the historical practice of conscious – "praxis". The representative of "pure science" isn't the learning, research subject. He is a public a person, which is the totality of all social definitions included in society and its constituent individuals. For such a "total subject" Object of interest is not something external; on the contrary, the latter appears as a product of his own activity. The scientific novelty examines trends in educational institutions and models of globalizing society in the context of our particular relationship of education and society, man and the state, and processes. The research and systematic analysis of neoliberal reforms at the level of society in general and education in particular are conducted. It examines substantive, structural and functional characteristics of the concept of «critical social philosophy of education» in the context of institutional tendencies of social life, as well as forms and possibilities of its methodological application. It consider a model of «critical social philosophy of education», as embodied in the programs of social development and learning, which are primarily designed to teach people how to lead an independent and original research themselves, society and knowledge systems. However, it is proved that the models and programs should not be cut off from any individual and the collective system of moral and social values, theoretical and applied training, nor from further use of the acquired values, norms and skills in everyday life, science, or in production, sphere of all social institutions. Conclusions. Critical philosophical, educational, pedagogical-psychological surprisingly theory, its models and concepts seek to redefine public and private and the public mind. Based on these grounds, in the future, it allows philosophy of education to develop a more inclusive philosophical vision of education, to apply directly to the problems of democratization and changes in social relations in the direction of equality and social justice in the field of education. The point of view of socio-philosophical and philosophical-еducational, pedagogical-psychological, normative understanding and social critics also requires the use of active efforts in the reconstruuction of education and society, the social vision of what education and human life can be and what their specific limitations in existing societies.

ABSTRACTThe probabilistic truth table task involves assessing the probability of "If A then C" conditional sentences. Previous studies have shown that a majority of participants assess this probability as the conditional probability P while a substantial minority responds with the probability of the conjunction A and C. In an experiment involving 96 participants, we investigated the impact on the rate of conjunctive responses of the context in which the task is framed. We show that a context intended to (...) lead participants to consider all the possible cases elicited more conjunctive responses than a context assumed not to have this effect. These results suggest that the step of inferring the probability can distort our assessment of participants' interpretation of conditional sentences. This might compromise the validity of the probabilistic task in studying conditional reasoning. (shrink)

120 students in grades 3 to 7 (aged 8 to 13) heard an argumentative text and were immediately submitted to a free recall task. The results show that before grade 7, the subjects did not view the text as argumentative. The discussion centers on the relevancy of a prototypical argumentative schema in accounting for these findings.

The perception of time cannot be reduced to a simple percept produced by an internal clock. The aim of the present study was therefore to investigate the role of the individual consciousness of time on temporal judgments. In the present study, the participants’ awareness of attention-related time distortions was assessed using a metacognitive questionnaire. The participants were also required to verbally judge a series of stimulus durations in a single or a dual task condition. The results revealed that time (...) was underestimated in the dual task compared to the single task. However, the accuracy of time judgments improved in line with the participants’ individual awareness of attentional time distortion: The more aware they were of the role of attention in time perception, the lower the time distortions they exhibited. Conscious awareness of time therefore plays a role in the accuracy of the time judgments made by human beings. (shrink)

The rational status of the Bayesian calculus for revising likelihoods is compromised by the common but still unfamiliar phenomenon of information distortion. This bias is the distortion in the evaluation of a new datum toward favoring the currently preferred option in a decision or judgment. While the Bayesian calculus requires the independent combination of the prior probability and a new datum, information distortion invalidates such independence (because the prior influences the datum). Although widespread, information distortion has (...) not generally been recognized. First, individuals are not aware when they themselves commit this bias. In addition, it is often hidden in more obvious suboptimal phenomena. Finally, the Bayesian calculus is usually explained only with undistortable data like colored balls drawn randomly. Partly because information distortion is unrecognized by the individuals exhibiting it, no way has been devised for eliminating it. Partial reduction is possible in some situation such as presenting all data simultaneously rather than sequentially with revision after each datum. The potential dangers of information distortion are illustrated for three professional revision tasks: forecasting, predicting consumer choices from internet data, and statistical inference from experimental results. The optimality of the Bayesian calculus competes with people’s natural desire that their belief systems remain coherent in the face of new data. Information distortion provides this coherence by biasing those data toward greater agreement with the currently preferred position – but at the cost of Bayesian optimality. (shrink)

Having an agreed-upon definition of character education would be useful for both researchers and practitioners in the field. However, even experts in character education disagree on how they would define it. We attempted to achieve greater conceptual clarity on this issue through a prototype analysis in which the features perceived as most central to character education were identified. In Study 1 (N = 77), we asked character education experts to enumerate features of character education. Based on these lists, we (...) identified 30 features. In Study 2 (N = 101), experts assessed which features were central to character education through a categorization task. In Study 3 (N = 166), we assessed the extent of centrality using scalar items. We conclude by offering practical advice for the development of future character education studies and programs rooted in what is deemed central to such programs. (shrink)

This paper reports a study of planning processes in the five-disc Tower of London (TOL) task in 20 younger and 20 older adult participants. A concurrent direct ''think-aloud'' method was used to obtain data on planning processes prior to moving discs in the TOL. A check was made of the effects of verbalising by comparing performance data from the experimental groups with data from control groups who did not verbalise during planning or moving. Verbalising slowed down planning and moving (...) but did not appear to distort the participants' approaches to the task. Older and younger participants did not differ in average moves taken to solve the tasks. However, older participants' planning was less complete and more error-prone than that of younger participants. The planning processes were characterised as showing a means-ends ''goal selection'' strategy. In this strategy participants (1) identify a single active goal disc at the start, (2) select moves and move sequences to enable the placing of the current goal disc in its target position, and (3) continue in this way until all discs are in their target positions. Age differences were found in the planning stage, during which there was no stimulus support and hence a substantial working memory load. During the move phase there was stimulus support and hence little loading of working memory. Age differences in moves required were not found in the move phase. As older participants tend to have depleted working memory capacity the present results suggest that working memory is heavily loaded in TOL planning but less so in the move phase of TOL. (shrink)

The paper introduces the problem of unawareness into multi-dimensional Principal–Agent theory. We introduce two key parameters to describe the problem, the extent and the effect of unawareness, show under what conditions it is optimal for the Principal to propose an incomplete or a complete contract, and characterize the incentive power of optimal linear contracts. If Agents differ in their unawareness, optimal incentive schemes can be distorted for both aware and unaware Agents, because, different from standard contract theory, the single-crossing property (...) fails to hold. In this case, even aware Agents can be subject to inefficiently high or low incentives. (shrink)

Optical distortions as a visual disturbance are inherent in many optical devices such as spectacles or virtual reality headsets. In such devices, distortions vary spatially across the visual field. In progressive addition lenses, for example, the left and right regions of the lens skew the peripheral parts of the wearers visual field in opposing directions. The human visual system adapts to homogeneous distortions and the respective aftereffects are transferred to non-retinotopic locations. This study investigates simultaneous adaptation to two opposing distortions (...) at different retinotopic locations. Two oppositely skewed natural image sequences were presented to 10 subjects as adaptation stimuli at two distinct locations in the visual field. To do so, subjects were instructed to keep fixation on a target. Eye tracking was used for gaze control. Change of perceived motion direction was measured in a direction identification task. The point of subjective equality, that is, the angle at which a group of coherently moving dots was perceived as moving horizontal, was determined for both retinal locations. The shift of perceived motion direction was evaluated by comparing PSE before and after adaptation. A significant shift at both retinal locations in the direction of the skew distortion of the corresponding adaptation stimulus is demonstrated. Consequently, parallel adaptation to two opposing distortions in a retinotopic reference frame was confirmed by this study. (shrink)

This book critically investigates the notion of democracy without demos by unravelling the link that modern history has established between the concepts of democracy and the sovereignty of the people. This task is imposed on us by globalization. The individualization of the subject of rights is the result of the destruction of regimes of special rights of ancient societies by the centralizing action of a territorial power. This individualization, because it implies equality, has created a new form of political (...) subjectivity that has been the driving force of the democratization of democracies during the 19th and 20th centuries. Democracy and subjective rights discusses how asserting itself as the only guarantor of rights, the modern state has also nationalized citizenship. However, the author argues, the legal and judicial monopoly of the nation-state is weakened today by the multiplication and heterogeneity of the powers on which the rights of individuals depend. This situation forces us to denationalize citizenship without sacrificing, however, the specific form of political subjectivity that the individualization of rights has made possible. (shrink)

At conceptual and linguistic levels of cognition, events are said to be represented in terms of abstract categories, for example, the sentence Jackie cut the bagel with a knife encodes the categories Agent (i.e., Jackie) and Patient (i.e., the bagel). In this paper, we ask whether entities such as the knife are also represented in terms of such a category (often labeled “Instrument”) and, if so, whether this category has a prototype structure. We hypothesized the Proto-instrument is a tool: (...) a physical object manipulated by an intentional agent to affect a change in another individual or object. To test this, we asked speakers of English, Dutch, and German to complete an event description task and a sentence acceptability judgment task in which events were viewed with more or less prototypical instruments. We found broad similarities in how English, Dutch, and German partition the semantic space of instrumental events, suggesting there is a shared concept of the Instrument category. However, there was no evidence to support the specific hypothesis that tools are the core of the Instrument category—instead, our results suggest the most prototypical Instrument is the direct extension of an intentional agent. This paper supports theoretical frameworks where thematic roles are analyzed in terms of prototypes and suggests new avenues of research on how instrumental category structure differs across linguistic and conceptual domains.

It is proposed that there are important generalizations about problem solving in design activity that reach across specific disciplines. A framework for the study of design is presented that (a) characterizes design as a radial category and fleshes out the task environment of the prototypical cases; (b) takes the task environment seriously; (c) shows that this task environment occurs in design tasks, but does not occur in every nondesign task; (d) explicates the impact of this (...) class='Hi'>task environment on the design problem space; and (e) demonstrates that, given the structure of the information-processing system, the features noted in the problem spaces of design tasks will not all occur in problem spaces where the task environment is vastly different. This analysis leads to the claim that there are a set of invariant features in the problem spaces of design situations that collectively constitute a design problem space. Protocol studies are reported in which the problem spaces of three design tasks in architecture, mechanical engineering, and instructional design are explored and compared with several protocols from nondesign problem-solving tasks.

Substance ontologists claim that substances are ontologically primary because the category of substance enjoys unique explanatory potential. Unless it can be shown that "only" substances fulfill the central explanatory tasks in ontology, this inference from explanatory success to ontological primacy amounts to a fallacy akin to the error Whitehead called 'the fallacy of misplaced concreteness'. I investigate recent prototypical arguments for substance metaphysics and try to show that some explanatory functions of substance can also be fulfilled by other ontological categories. (...) In particular, I argue against M. Ayers that there is no reason to think that all and only substances are discrete individuals, natural wholes, and logical units. I conclude that the category of substance does not provide us with a uniquely powerful explanans for the notion of logical and physical unity. (shrink)

A variety of evidence demonstrates that memory is a reconstructive process prone to errors and distortions. However, the complex relationship between memory encoding, strength of memory reactivation, and the likelihood of reporting true or false memories has yet to be ascertained. We address this issue in a setting that mimics a real-life experience: We asked participants to take a virtual museum tour in which they freely explored artworks included in the exhibit, while we measured the participants’ spontaneous viewing time of (...) each explored artwork. In a following memory reactivation phase, participants were presented again with explored artworks, followed by novel artworks not belonging to the same exhibit. For each of these objects, participants provided a reliving rating that indexed the strength of memory reactivation. In the final memory recognition phase, participants underwent an old/new memory task, involving reactivated vs. baseline targets, and activated and baseline lures. The results showed that those targets that were spontaneously viewed for a longer amount of time were more frequently correctly recognized. This pattern was particularly true for reactivated targets associated with greater memory strength. Paradoxically, however, lures that were presented after targets associated with higher reliving ratings in the reactivation phase were more often erroneously recognized as artworks encountered during the tour. This latter finding indicates that memory intrusions, irrespective of the viewing time, are more likely to take place and be incorporated into true memories when the strength of target memory is higher.

In _The Politics of Decolonial Investigations_ Walter D. Mignolo provides a sweeping examination of how coloniality has operated around the world in its myriad forms from the sixteenth century to the twenty-first. Decolonial border thinking allows Mignolo to outline how the combination of the self-fashioned narratives of Western civilization and the hegemony of Eurocentric thought served to eradicate all knowledges in non-European languages and praxes of living and being. Mignolo also traces the geopolitical origins of racialized and gendered classifications, modernity, (...) globalization, and cosmopolitanism, placing them all within the framework of coloniality. Drawing on the work of theorists and decolonial practitioners from the Global South and the Global East, Mignolo shows how coloniality has provoked the emergence of decolonial politics initiated by delinking from all forms of Western knowledge and subjectivities. The urgent task, Mignolo stresses, is the epistemic reconstitution of categories of thought and praxes of living destituted in the very process of building Western civilization and the idea of modernity. The overcoming of the long-lasting hegemony of the West and its distorted legacies is already underway in all areas of human existence. Mignolo underscores the relevance of the politics of decolonial investigations, in and outside the academy, to liberate ourselves from canonized knowledge, ways of knowing, and praxes of living.

Repression has become an empirical fact that is at once obvious and problematic. Fragmented clinical and laboratory traditions and disputed terminology have resulted in a Babel of misunderstandings in which false distinctions are imposed (e.g., between repression and suppression) and necessary distinctions not drawn (e.g., between the mechanism and the use to which it is put, defense being just one). “Repression” was introduced by Herbart to designate the (nondefensive) inhibition of ideas by other ideas in their struggle for consciousness. Freud (...) adapted repression to the defensive inhibition of “unbearable” mental contents. Substantial experimental literatures on attentional biases, thought avoidance, interference, and intentional forgetting exist, the oldest prototype being the work of Ebbinghaus, who showed that intentional avoidance of memories results in their progressive forgetting over time. It has now become clear, as clinicians had claimed, that the inaccessible materials are often available and emerge indirectly (e.g., procedurally, implicitly). It is also now established that the Ebbinghaus retention function can be partly reversed, with resulting increases of conscious memory over time (hypermnesia). Freud's clinical experience revealed early on that exclusion from consciousness was effected not just by simple repression (inhibition) but also by a variety of distorting techniques, some deployed to degrade latent contents (denial), all eventually subsumed under the rubric of defense mechanisms (“repression in the widest sense”). Freudian and Bartlettian distortions are essentially the same, even in name, except for motive (cognitive vs. emotional), and experimentally induced false memories and other “memory illusions” are laboratory analogs of self-induced distortions. Key Words: avoidance; Bartlett; defense; denial; distortion; Ebbinghaus; false-memories; Freud; inhibition; repression; suppression. (shrink)

The study of emotional concepts stands at a very interesting intersection between the theoretical debate about the nature of emotions and the debate about the nature of processing concrete concepts and abstract concepts. On the one hand, it is debated whether it is possible to differentiate basic emotions from secondary emotions and, on the other hand, whether emotional concepts differ from abstract concepts. In this regard, the prototypical perceptual aspects are considered an important factor both for the differentiation between concrete (...) and abstract concepts and for the differentiation between basic and secondary emotions (facial expressions). Thus, the objective has been to determine if (a) the presence or absence of a prototypical perceptual referent, and (b) the type of concept (referring to emotion and not referring to emotion), produce differences between concepts of basic emotions, secondary emotions and concepts not related to emotions, concrete and abstract, in the tasks of qualification of concreteness, imageability and availability of context and the task of the list of properties, that have been used in previous studies. A total of 86 university students from the suburbs of La Serena - Coquimbo (Chile), all native Spanish speakers, participated in the study. The results show that in the perception of concreteness and in the total of enumerated properties, emotional concepts presented similar results to abstract concepts not related to emotion and there was no difference between basic and secondary emotion concepts. In imageability and context availability, emotional concepts were perceived as different from and more concrete than abstract concepts. In addition, the cause-effect type attributes allowed to clearly differentiate emotional concepts from those not related to emotion and to differentiate between basic and secondary emotion concepts. These types of attributes appear almost exclusively in emotional concepts and are more frequent in basic emotions. These results are partially consistent with the predictions of Neurocultural and Conceptual Act theories about emotions. (shrink)

It has been claimed that the prototype theory of concepts supports two controversial claims in the philosophy of art: that art cannot be defined, and that the possession of a certain sort of historical narrative is a sufficient but not necessary means of determining the art status of contested works. It is argued here that two sorts of considerations undermine the thesis that prototype theory offers significant support to anti-definitionism and historical narrativism. First, there is reason to think (...) that prototype theory is as a psychological theory not the sort of view that can support philosophical theories like anti-definitionism and historical narrativism. Second, well-known objections and theoretical alternatives to prototype theory theory raise serious questions about that theory’s own credentials. (shrink)

In our work we have drawn attention to an aspect of conscious experience that we have labeled chromatic illumination, which consists of conscious appreciation of a large body of background information, and of the holistic relevance of this information to a cognitive task that is being consciously undertaken, without that information being represented by any conscious, occurrent, intentional mental state. We have also characterized the prototypical causal role of chromatic-illumination features of conscious intentional states, and we have detailed the (...) specific kind of physical-to-mental supervenience situation that would need to obtain in order for a chromatically illuminated conscious intentional state to figure as a supervenient mental cause of one’s subsequent cognition and behavior. In this paper we answer two residual questions. The first is a “How possible?” question, asking whether such a supervenience scenario is really a coherent conceptual possibility, given that it posits a putative conscious feature of conscious experience that allegedly plays a conscious causal role that supposedly constitutes conscious appreciation of information not being consciously represented. The second is a “How plausible?” question, asking whether the details of such a physical-to-mental supervenience scenario can be spelled out in a way that makes actually plausible the claim that chromatic illumination actually gets physically implemented this way in the human brain. We argue that the supervenient causal efficacy of chromatically illuminated conscious experience is not only a genuine conceptual possibility, but also very plausibly can really occur in humans.

Categorization behavior can be fruitfully analyzed in terms of the trade‐off between as high as possible faithfulness in the transmission of information about samples of the classes to be categorized, and as low as possible transmission costs for that same information. The kinds of categorization behaviors we associate with conceptual atoms, prototypes, and exemplars emerge naturally as a result of this trade‐off, in the presence of certain natural constraints on the probabilistic distribution of samples, and the ways in which we (...) measure faithfulness. Beyond the general structure of categorization in these circumstances, the same information‐centered perspective can shed light on other, more concrete properties of human categorization performance, such as the results of certain prominent experiments on supervised categorization.

Quantitative losses of memory content imply replicative processing; correspondence losses imply reconstructive processing. Research should focus on the relationship between these processes by obtaining accuracy- and quantity-based indicators of memory within the same framework. This approach will also yield information about the effects of task and individual-difference variables on loss and distortion, as well as the time course of each process.

Much research has focused on intergenerational learning. However, its patterns and processes have rarely been explored. Therefore, this study aimed to develop a coding scheme for intergenerational learning, and to explore the patterns of collaborative communication emerging in the context of intergenerational learning. A total of 16 individuals participated in the study. Participants were invited to design digital games with their intergenerational team members. Of all the interactions, two sets of collaborative interactions were coded and analyzed. The findings revealed that (...) the coding scheme for intergenerational learning was developed with high inter-rater reliability for three sub-systems: power process, communication skills, and responses to bids. Additionally, although the patterns of collaborative communication showed a balance of power during the task involving the collection of game elements, younger learners dominated during the task of completing the game prototype.

Understanding the relationship of democracy and property ownership is one of the most important tasks for contemporary political philosophy. In his concept of property-owning democracy John Rawls explores the thesis that property in productive means has an indirect effect on the formation of true or false beliefs and that unequal ownership of productive capital leads to distorted and deceived convictions. The basic aspect of Rawls’s conception can be captured by the claim that for securing the fair value of the political (...) liberties a widespread dispersal of property in productive resources is required that minimizes the formation of delusions and therefore improves the conditions of deliberative democracy.

Interactional competence has attracted increasing attention due to its significance for language users. Previous studies concerning interactional competence mainly focus on synchronous interaction tasks, while the utilization of asynchronous interaction tasks is relatively under-explored despite the importance of asynchronous interaction in real life. Taking the “Responding To Forum Posts” task used in the International Undergraduate English Entrance Examination at Shanghai Jiao Tong University as an example, the study aims to validate the use of asynchronous interaction tasks in the assessment (...) of learner’s interactional competence. 49 students’ performances on the RTFP task were collected through a prototype test of the IUEEE in 2021. The data were analyzed through content analysis, analysis of variance, and ordinal logistic regression. The results showed that the task elicited a wide range of interactional features and test-takers at different proficiency levels differed significantly in the variety of features and the amount of emotion-based interaction. The study also found significant correlations between some of the features and test takers’ overall performance on interactional competence. The study has provided validity evidence for the RTFP task in the assessment of interactional competence and thrown light on the construct of asynchronous written interactional competence. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:On the Importance of Conceptual ContrastsMadness, Reason, and Mad PrideAwais Aftab, MD (bio)Garson (2023) offers an engaging historical and philosophical discussion around the importance Late Modern thinkers assigned to the task of differentiating madness from idiocy (or more specifically, to the tripartite distinction of sanity, madness, and idiocy). Based on this analysis, Garson’s identifies the need to offer a positive account of mental illness—one that does not define (...) the essence of mental illness exclusively as the absence, lack, or failure of the power of reasoning. Following the Late Modern thinkers (Locke, Kant, Wigan, and Heinroth), Garson concludes that madness is infused with reason, and what characterizes madness is the presence of reason in an altered and mutated form. This is all worth taking seriously. My own assessment of this historical and philosophical material nonetheless differs from that of Garson. To recognize madness as possessing reason within it in an altered form may be of less profound significance than he thinks it is. Garson’s discussion commendably highlights the importance of making conceptual contrasts explicit in definitional debates, and this should indeed lead us to search for contrasts that are more philosophically illuminating (what is better will depend on the context of inquiry). However, in my view, the recognition of madness as altered reason neither reframes the project of defining “mental disorder” nor does it provide an intellectual scaffolding for mad activism.The significance of “madness contains reason within in but in an altered or perverse form” is difficult to translate into contemporary scientific terms, and the fuzziness and historical baggage around the terms “madness,” “reason,” and “perversion” does not make it easy. “Mental disorder” or “psychopathology” means to us something quite different than what madness meant to Late Modern thinkers, and while “madness” remains a popular term in philosophical literature, there is no clarity on the nature of overlap between the domain of madness and the domain of conditions currently classified by the diagnostic manuals. Mental disorders, as currently conceptualized, include a motley of conditions that were previously characterized using terms such as idiocy, madness, neuroses, and psychopathic personalities. [End Page 297]From our contemporary vantage point, to compare idiocy and madness is to make a distinction within the domain of psychopathology. We are comparing two groups of psychiatric conditions. The lessons we derive from this comparison do not necessarily extrapolate well to a comparison of mental disorders with something outside the domain of psychopathology. To the extent that psychopathology is inclusive of both idiocy and madness, psychiatric disorders both contain and do not contain “reason” within them. The domain is heterogenous in this regard, and broad generalizations about the nature of reason in the mental disorders would be simplistic at best and inaccurate at worst. Other distinctions that we have made within the domain of psychopathology have included organic versus functional, neurosis versus psychosis, categories versus continua, and distinctions used within nosology have included operationalized criteria versus phenomenology, idiographic versus nomothetic, medical versus non-medical, description versus explanation, and so on (Aftab & Ryznar, 2021; Zachar, Banicki, & Aftab, 2023), all of which have the potential to offer a positive account of some aspect of psychopathology.It is worth nothing that the distinction between “absence of reason” versus “perversion of reason” is analogous to the common distinction between absence of function and altered function in patho-physiology. Such a distinction exists for almost every function that exists. Consider vision: absence of vision (blindness) and altered vision (illusions, distortions, hallucinations). Consider hypoesthesia (reduced sense of touch) and paraesthesia (altered sense of touch—tingling, pricking, burning, etc.). Garson alludes to diminished sexual capacity versus paraphilia as an analogy, but he does not seem to appreciate that the analogy applies much more broadly. Is the distinction between absence of reason versus perversion of reason of any greater significance than the distinction between blindness and hallucination? If we were to say, “What distinguishes hallucination from blindness is not the failure, absence, or lack of sight, but its presence—albeit in a perverse and mutated form,” how profound would it really be for our notions of disorder? Or imagine some Late Modern physician saying that a disturbance of speech and... (shrink)

In a previous paper the concept of disease was fuzzy-logically analyzed and a sketch was given of a prototype resemblance theory of disease (Sadegh-Zadeh (2000). J. Med. Philos., 25:605–38). This theory is outlined in the present paper. It demonstrates what it means to say that the concept of disease is a nonclassical one and, therefore, not amenable to traditional methods of inquiry. The theory undertakes a reconstruction of disease as a category that in contradistinction to traditional views is not (...) based on a set of common features of its members, that is individual diseases, but on a few best examples of the category, called its prototypes, and a similarity relationship such that a human condition is considered a disease if it resembles a prototype. It enables new approaches to resolving many of the stubborn problems associated with the concept of disease. (shrink)

The modifier effect refers to the fact that the perceived likelihood of a property in a noun category is diminished if the noun is modified. For example, “Pigs live on farms” is rated as more likely than “Dirty pigs live on farms.” The modifier effect has been demonstrated in many studies, but the underlying cognitive mechanisms are still unclear. This paper reports two series of experiments that jointly point to the conclusion that the modifier effect is the result of a (...) superposition of three cognitive mechanisms: (a) probabilistically softened default inheritance, (b) pragmatic implicatures due to Gricean relevance assumptions, and (c) inference based on world knowledge. We present evidence that the pragmatic effects operate largely on an unconscious level and that their influence can be reduced by changing the presentation format of the cognitive task. (shrink)

To later generations, much of the moral philosophy of the twentieth century will look like a struggle to escape from utilitarianism. We seem to succeed in disproving one utilitarian doctrine, only to find ourselves caught in the grip of another. I believe that this is because a basic feature of the consequentialist outlook still pervades and distorts our thinking: the view that the business of morality is to bring something about . Too often, the rest of us have pitched our (...) protests as if we were merely objecting to the utilitarian account of what the moral agent ought to bring about or how he ought to do it. Deontological considerations have been characterized as “side constraints,” as if they were essentially restrictions on ways to realize ends. More importantly, moral philosophers have persistently assumed that the primal scene of morality is a scene in which someone does something to or for someone else. This is the same mistake that children make about another primal scene. The primal scene of morality, I will argue, is not one in which I do something to you or you do something to me, but one in which we do something together. The subject matter of morality is not what we should bring about, but how we should relate to one another. If only Rawls has succeeded in escaping utilitarianism, it is because only Rawls has fully grasped this point. His primal scene, the original position, is one in which a group of people must make a decision together. Their task is to find the reasons they can share. (shrink)

The present study examines the effect of priming on business ethical decision making. Priming is based on the idea that our perceptions, actions, and emotions are distorted by unconscious cues from our environment. Subjects were primed for either “politeness” or “rudeness” using a sentence completion task. Following the priming, the subjects were asked to react to a series of ethical scenarios. The results showed that subjects primed for “rudeness” perceived the scenarios as less unethical than subjects primed for “politeness”. (...) Similar results were observed in both the American and the Dominican samples. The results indicate that business ethical decision making is influenced by environmental factors we are unaware off.

On the mainstream view, consciences are valuable because they promote moral unity. However, conscience, so defined, will systematically prevent moral growth that threatens unity, even when unity has formed around oppressive moral values. This motivates Carolyn McLeod's alternative ‘Dynamic View’ whereby consciences are valuable to the extent that they are dynamic. Consciences are dynamic when they interact with our best moral judgements to shape or ‘retool’ the moral values underpinning conscience, sometimes at an initial cost to unity. We modify and (...) extend McLeod's account in two ways: (1) We object to her claim that conscience encourages its own retooling. We argue that the opposite is true – conscience creates a motivational barrier to change that moral judgement must overcome to successfully retool conscience. The task of ensuring dynamism, therefore, falls to moral judgement. (2) However, this motivational barrier enables conscience to play a valuable role that McLeod overlooks – compensating for the limitations of moral judgement. On our Balanced View, the value of conscience depends on it being sufficiently open to being shaped by our best moral judgements but inert enough to compensate for distorted moral judgements and to guide action when under cognitive load.

Given the potential dangers of unethical decisions in the workplace, it has become increasingly important for managers to hire, and promote into leadership positions, those who are morally inclined. Behavioral ethics research has contributed to this effort by examining an array of individual difference variables that play a role in morality. However, past research has focused mostly on direct causal effects and not so much on the processes through which different factors, especially those that are morality based, decrease unethical choices. (...) The purpose of the current research is to examine the process, which includes both subconscious and conscious decision pathways, through which moral attentiveness curbs unethical decision making at the individual level. The findings of a study employing about 200 participants and a cheating task reveal that both accurate ethical prototypes and moral awareness of the situation decreased unethical decisions, and moral attentiveness was found to be positively related to both of these constructs. In addition, having accurate ethical prototypes was found to be a partial mediator between perceptual moral attentiveness and less cheating, while moral awareness was found to be a partial mediator between reflective moral attentiveness and less cheating. The theoretical and practical implications of these findings are discussed. (shrink)

The article formulates the main issues that form the research field of the anthropology of sacrifice. The first group of problems is associated with a description of the fundamental anthropological nature of the phenomenon of sacrifice and answering the question of whether sacrifice is a cultural universal, and if so, what this universality can be based on, what prototypical forms of sacrifice can be identified and how they can be described. The second group of problems is associated with the (...) class='Hi'>task of understanding how the phenomenon of sacrifice is changing today and what anthropological meaning these changes have. In a situation where explicit human sacrifice is taboo, one can speak of the emergence of substitute practices and the emergence of analogs in which the structural elements of the classical ritual are distributed in space and time and are presented in a different order. As a result, in modern society, victims-sufferers are analogous to classical sacrificial victims and therefore often go through sacralizing rituals and practices. However, a fundamentally important question is whether a structure change in distributed sacrifice incurs a change in social functions? And if these changes exist, how essential they are, how much they affect the very semantic core of the anthropology of sacrifice. The third group of problems is associated with the sphere of praxis in its classical understanding, i.e., it represents issues related to political, economic, and ethical implications associated with the phenomenon of sacrifice and analogs of the ritual of sacrifice in modern societies. Here it is also impossible to avoid relating modern discourses and practices to archaic prototypes and identifying similarities and differences, and most importantly, describing transformations and problematizing their anthropological meaning. Since modern society is immersed in the media environment, it is extremely important to discuss the influence of the media on these processes. In general, the anthropology of sacrifice as a research project allows us to look at many of the most pressing social issues of our time from a new angle. (shrink)

This study aimed at evaluating the role of proprioception in the process of matching the final position of one's limbs with an intentional movement. Two experiments were realised with the same paradigm of conscious recognition of one's own limb position from a distorted position. In the first experiment, 22 healthy subjects performed the task in an active and in a passive condition. In the latter condition, proprioception was the only available information since the central signals related to the motor (...) command were likely to be absent. The second experiment was realised with a deafferented patient who suffers from a complete haptic deafferentation, including loss of proprioception. The results first argue in favour of a dominant role of proprioception in action recognition, but they also stress the possible role of central signals. The process of matching the final position of one's limbs with an intended movement and thus of action recognition would be achieved through a comparison process between the predicted sensory consequences of the action, which are stored in its internal model, and the actual sensory consequences of that action.

The purpose of this article is to bring to light a critical question which borders around the decolonial feminism discourse, and in so doing I unveil some salient insights which add valuable contributions to the discourse about the place of feminism in the African context. The motivating problem is the question of subordination of women in Africa. There are many reasons and questions, each deserving thorough examination that have been brought forward for the causes and possible explanations of the phenomenon. (...) The argument I seek to highlight is that cultural distortion through colonisation has led to the valorisation of narratives that perpetuate the subordination of women in Africa. One such narrative is that women are second-class citizens and that they occupy an inferior position in the social, economic and political hierarchies of our society. What will come from this article is that these narratives persist in what we would consider a postcolonial “modern” Africa where women seem to be gaining rights and tapping into spaces that foster equality owing to feminism. However, the subordination of women is still prevalent, even for the “liberated” women. The article will show why the persistence of this problem is proving difficult for the comprehension and acceptance of feminism in African contexts. (shrink)

Free Will & The Tragic Predicament : Making Sense of Williams -/- The discussion in this paper aims to make better sense of free will and moral responsibility by way of making sense of Bernard Williams’ significant and substantial contribution to this subject. Williams’ fundamental objective is to vindicate moral responsibility by way of freeing it from the distortions and misrepresentations imposed on it by “the morality system”. What Williams rejects, in particular, are the efforts of “morality” to further “deepen” (...) or “refine” the notion of the voluntary, with a view to securing “ultimate justice”. It is these aims and aspirations, he argues, that take us to the precipice of scepticism. In Shame and Necessity (1993) Williams advances a vindicatory genealogy that unmasks the “illusions” and “fantasies” of our current ethical ideas as they relate to agency and responsibility. What we are then left with is the task of “recasting our ethical conceptions” . It is here that Williams is especially insistent on the importance and value of historical consciousness and reflection. The role of our reflections about the Greeks and tragedy is precisely to show that in order to move forward, into the future, we need to first look back at where we have come from. The value of these “untimely” observations is that they provide us with alternatives and options that we might otherwise lack. What we discover, when we consider the Greeks, is their commitment to a “pessimism of strength” that rests on rejecting scepticism. It is this two-sided perspective on our ethical predicament that delivers a more truthful account of our human situation, one that will help us discard those illusions and fantasies of "morality" that we are “better off” without. An account of this kind refuses to accept an optimism that insists that any form of responsible ethical life must be one that is immune to the influence of luck and fate. This is the fundamental lesson that we can learn from the ancient Greeks and that Williams seeks to “recover” for us. (shrink)

Adaptive decision making and veridical decision making are based on different mechanisms. Veridical decision making is based on the identification of the correct response, which is intrinsic to the external situation and is actor-independent. Adaptive decision making is actor-centered and is guided by the actor's priorities. The prefrontal cortex is particularly critical for adaptive decision making and less so for veridical decision making. However, most experimental procedures used in cognitive psychology and neuropsychology focus on veridical decision making and ignore adaptive (...) decision making. Innovative experimental procedures are required to characterize the contribution of the prefrontal cortex to adaptive decision making. We have designed a prototype for such procedures, the Cognitive Bias Task, and present the novel findings generated by this task. (shrink)
