Embryonic stem cells (ESCs) are now classified into two types of pluripotency: “naïve” and “primed” based upon their differing characteristics. Conventional human ESCs have much more in common with mouse epiblast stem cells and are now deemed to be primed. Naïve human ESCs that resemble mouse ESCs have recently been generated from their primed counterpart by cellular reprogramming. Isolation of naïve hESCs from human embryos has proven to be difficult. Is the inability to capture (...) naïve hESCs the result of suboptimal derivation conditions or because they are so transient they cannot be “captured” in vitro? Prevailing evidence surrounding this issue are inconclusive and require additional human embryo research. However, negative public opinion regarding human embryo research, may make this an uphill battle. The solution may come from cellular reprogramming. (shrink)

Psychology does not get rid of its problems by taking experience at its face value, for it is the province of psychology to study problems arising when experience is taken at its face value. Only in actual lived experience is concrete reality to be found in its fullest sense. All reality which is experience includes attributes both spatial and temporal. Objects cannot b7 considered in the first place apart from such attributes. Physical objects are perceived as parts of a total (...) situation and there is merit in the suggestion of the Gestalt psychologists. Always much will be found in the perceptum which will not correspond with the physical object, since the physical object is only an abstract. The effort to control our environment has led to a sophisticated attitude toward perceptual experience, which is said in psychological circles to lead to the stimulus error. Those who have seen children gradually grow into a realization of the unreliability of perception—for purposes of muscular manipulation—will understand what is meant.

Prime matter plays an indispensable role in Aristotle’s philosophy, enabling him to avoid the pitfalls of both naïve Platonism and nominalism. Prime matter is best thought of as a kind of infinitely divisible and atomless bare particularity, grounding the distinctness of distinct members of the same species. Such bare particularity is needed in symmetrical situations, like a world consisting of indistinguishable Max Black spheres. Bare particularity is especially important in modern physics, given the homogeneity and isotropy of space. With (...) the importance of fields in classical, relativistic, and quantum physics, we have good reason to prefer something like Aristotle’s continuous, infinitely divisible matter over indivisible particles. Mass and energy in relativistic physics also points in the direction of prime matter as the enduring substrate of these quantities. Recent work on Aristotelian interpretations of quantum mechanics, further underscores the contemporary relevance of prime matter. (shrink)

Semantic priming has been a focus of research in the cognitive sciences for more than 30 years and is commonly used as a tool for investigating other aspects of perception and cognition, such as word recognition, language comprehension, and knowledge representations. Semantic Priming: Perspectives from Memory and Word Recognition examines empirical and theoretical advancements in the understanding of semantic priming, providing a succinct, in-depth review of this important phenomenon, framed in terms of models of memory and models of word recognition. (...) The first section examines models of semantic priming, including spreading activation models, the verification model, compound-cue models, distributed network models, and multistage activation models (e.g. interactive-activation model). The second section examines issues and findings that have played an especially important role in testing models of priming and includes chapters on the following topics: methodological issues (e.g. counterbalancing of materials, choice of priming baselines); automatic vs. strategic priming; associative vs. "pure" semantic priming; mediated priming; long-term semantic priming; backward priming; unconscious priming; the prime-task effect; list context effects; effects of word frequency, stimulus quality, and stimulus repetition; and the cognitive neuroscience of semantic priming. The book closes with a summary and a discussion of promising new research directions. The volume will be of interest to a wide range of researchers and students in the cognitive sciences and neurosciences. (shrink)

Priming is a useful tool for ascertaining the circumstances under which previous experiences influence behavior. Previously, using hierarchical stimuli, we demonstrated (Justus & List, 2005) that selectively attending to one temporal scale of an auditory stimulus improved subsequent attention to a repeated (vs. changed) temporal scale; that is, we demonstrated intertrial auditory temporal level priming. Here, we have extended those results to address whether level priming relied on absolute or relative temporal information. Both relative and absolute temporal information are important (...) in auditory perception: Speech and music can be recognized over various temporal scales but become uninterpretable to a listener when presented too quickly or slowly. We first confirmed that temporal level priming generalized over new temporal scales. Second, in the context of multiple temporal scales, we found that temporal level priming operates predominantly on the basis of relative, rather than absolute, temporal information. These findings are discussed in the context of expectancies and relational invariance in audition. (shrink)

Previous work has demonstrated that simple geometric shapes may convey emotional meaning using various experimental paradigms. However, whether affective meaning of simple geometric shapes can be automatically activated and influence the evaluations of subsequent stimulus is still unclear. Thus the present study employed an affective priming paradigm to investigate whether and how two geometric shapes (circle vs. downward triangle) impact on the affective processing of subsequently presented faces (Experiment 1) and words (Experiment 2). At behavioral level, no significant effect of (...) affective congruency was found. However, ERP results in Experiment 1 and 2 showed a typical effect of affective congruency. The LPP elicited by affectively incongruent trials was larger compared to congruent trials. Our results provide support for the notion that downward triangle is perceived as negative and circle as positive and their emotional meaning can be activated automatically and then exert an influence on the electrophysiological processing of subsequent stimuli. The lack of significant congruent effect in behavioral measures and the inversed N400 congruent effect might reveal that the affective meaning of geometric shapes is weak because they are just abstract threatening cues rather than real threat. In addition, because no male participants are included in the present study, our findings are limited to females. (shrink)

In many simple integral domains, such as Z or Z[i], there is a straightforward procedure to determine if an element is prime by simply reducing to a direct check of finitely many potential divisors. Despite the fact that such a naive approach does not immediately translate to integral domains like Z[x] or the ring of integers in an algebraic number field, there still exist computational procedures that work to determine the prime elements in these cases. In contrast, we will show (...) how to computably extend Z in such a way that we can control the ordinary integer primes in any Π20 way, all while maintaining unique factorization. As a corollary, we establish the existence of a computable unique factorization domain such that the set of primes is Π20-complete in every computable presentation. (shrink)

Riassunto: Nell’età dello sviluppo, i bambini iniziano a comprendere e a produrre le prime espressioni ironiche, in particolare nel contesto familiare. Sebbene sia comprensione sia produzione di ironia richiedano abilità linguistiche, pragmatiche, di Teoria della Mente e di tipo socio-comunicativo, non è ancora chiaro come tali abilità entrino in gioco nel caso della produzione del sarcasmo. Questo contributo ripercorre gli studi principali sulla comprensione vs. produzione dell’ironia in età evolutiva, mettendo in evidenza il ruolo delle capacità affettive e argomentative necessarie (...) alla produzione dell’ironia e del sarcasmo. In riferimento a studi recenti, si ipotizza che le capacità di Mind-mindedness genitoriale possano influenzare lo sviluppo delle capacità di lettura della mente e, più in particolare, gli aspetti affettivi e relazionali nel processo di comprensione dell’ironia. Si ipotizza altresì che la produzione dell’ironia, e in particolare del sarcasmo, sia modulata non solo dalle capacità affettive ma anche da quelle argomentative in via di sviluppo. Parole chiave: Produzione del sarcasmo; Capacità affettive; Capacità argomentative; Comprensione; Teoria della mente Comprehension vs. Production of Sarcasm: The role of the affective and argumentative capacities in childhood: Children start comprehending and producing their first ironic expressions quite early especially in the family environment. The comprehension and the production of irony require linguistic, pragmatic, social and communicative capacities as well as abilities related to the Theory of Mind. However, it is not yet clear how these abilities are involved in the production of sarcasm. In this manuscript we review the main studies on the production of irony in childhood in order to identify the affective and argumentative capacities that are needed for the production of irony and sarcasm and the specific role they play in that. On the basis of these studies, we hypothesize that parental mind-mindedness promote children’s development of mindreading capacities and, more specifically, of those affective and relational aspects needed for the comprehension of irony. Moreover, we also argue that the production of irony and even more of sarcasm depends not only on the affective capacities but also on the developing argumentative capacities of the children. Keywords: Production of Sarcasm; Affective Capacities; Argumentative Capacities; Comprehension, Theory of Mind. (shrink)

This article examines genealogical investigations in an attempt to explain what they are, how they work, and what purpose they serve. It is a critique of Robert Brandom’s view of genealogists as naïve semanticists who believe that normative thinking, as it relates to all forms of epistemic inquiry and language use, is reducible to naturalistic causes. This reduction, Brandom claims, is hopelessly misguided and semantically incoherent since genealogies are not epistemically neutral in that “they count no more and no (...) less,” as Habermas put it, than the traditional accounts of moral phenomena that they seek to replace. Nietzsche’s “story” of the origin of guilt in On the Genealogy of Morals is thus not even a useful fiction but merely meaningless. My analysis shows that Brandom’s understanding of genealogy is rather simplistic. While genealogists are naturalists insofar as they attempt to discover the specific historical causes that gave rise to current normative practices, they are neither reductive empiricists nor first-stage semanticists, as Brandom calls them, but multidimensional power-pragmatists.

Recent reports that human pluripotent stem cells can be captured in a spectrum of states with variable properties has prompted a re‐evaluation of how pluripotency is acquired and stabilised. The latest additions to the stem cell hierarchy open up opportunities for understanding human development, reprogramming, and cell state transitions more generally. Many of the new cell lines have been collectively termed ‘naïve’ human pluripotent stem cells to distinguish them from the conventional ‘primed’ cells. Here, several transcriptional and epigenetic (...) hallmarks of human pluripotent states in the recently described cell lines are reviewed and evaluated. Methods to derive and identify human naïve pluripotent stem cells are also discussed, with a focus on the uses and future developments of state‐specific reporter cell lines and cell‐surface proteins. Finally, opportunities and uncertainties in naïve stem cell biology are highlighted, and the current limitations of human naïve pluripotent stem cells considered, particularly in the context of differentiation.

Much of early western research has focused on identity. A primed identity can inhibit the priming of other alternative identities, and also negatively affect the intention to purchase products related to those alternative identities. In western culture, individuals operate within a cultural framework that makes them more likely to prioritize their own goals and less likely to rely on environmental factors when evaluating others. Individuals are more likely to choose products that fit their primed identity. In this study, (...) we suggest that in collectivist Chinese culture, individuals may give priority to group-level goals and attach more importance to situational factors when evaluating others. Therefore, a primed identity may not necessarily inhibit the priming of alternative identities. In this research, we examine the association between a focal identity and alternative identities, with particular emphasis on the accessibility, discrepancies, and effects on purchase intention of alternative identities. We also examine the intent to purchase products related to the alternative identity vs. the focal identity, developing a model with which to explore this construct. We test four hypotheses through experiments using an online questionnaire and analyzing the resulting data using statistical product service solutions 22.0 and the PROCESS macro modeling tool. The results are as follows: First, the association between a focal identity and alternative identity has a positive impact on the accessibility of the alternative identity. The clearer the alternative identity is, the greater the impact of the association between the focal identity and alternative identity on the latter’s accessibility. Second, the accessibility of the alternative identity has a positive impact on the intent to purchase alternative identity vs. focal identity-related products. The greater the discrepancy between the focal identity and the alternative identity, the greater the impact on the intent to purchase alternative identity vs. focal identity-related products. The results of this study confirmed the interaction between identity association and the clarity of the alternative identity, as well as the influence of the accessibility of the alternative identity on the intent to purchase alternative identity vs. focal identity-related products. We contribute to the development of a theory on intention to purchase identity-related products. (shrink)

The role of prefrontal cortex (PFC) in influencing creative thinking has been investigated by many researchers who, while succeeding in proving an effective involvement of PFC, reported suggestive but sometimes conflicting results. In order to better understand the relationships between creative thinking and brain activation in a more specific area of the PFC, we explored the role of dorsolateral PFC (DLPFC). We devised an experimental protocol using transcranial direct-current stimulation (tDCS). The study was based on a 3 (kind of stimulation: (...) anodal vs. cathodal vs. sham) × 2 (priming: divergent vs. convergent) design. Forty-five healthy adults were randomly assigned to one stimulation condition. Participants’ creativity skills were assessed using the Product Improvement subtest from the Torrance Tests of Creative Thinking (TTCT). After 20 min of tDCS stimulation, participants were presented with visual images of common objects. Half of the participants were instructed to visualize themselves using the object in an unusual way (divergent priming), whereas the other half were asked to visualize themselves while using the object in a common way (convergent priming). Priming was aimed at inducing participants to adopt different attitudes toward the creative task. Afterwards, participants were asked to describe all of the possible uses of the objects that were presented. Participants’ physiological activation was recorded using a biofeedback equipment. Results showed a significant effect of anodal stimulation that enhanced creative performance, but only after divergent priming. Participants showed lower skin temperature values after cathodal stimulation, a finding which is coherent with studies reporting that, when a task is not creative or creative thinking is not prompted, people show lower levels of arousal. Differences in individual levels of creativity as assessed by the Product Improvement test were not influential. The involvement of DLPFC in creativity has been supported, presumably in association to shift of attention modulated by priming. (shrink)

There is a tension at the heart of Lucy Allaiss transcendental idealism. The problem arises from her use of two incompatible theories in contemporary philosophy - relationalism about perception, or naïve realism, and relationalism about colour, or more generally relationalism about any such perceptual property. The problem is that the former requires a more robust form of realism about the properties of the objects of perception than can be accommodated in the partially idealistic framework of the latter. On Allais’ (...) interpretation, Kant’s notorious attempt to balance realism and idealism remains unstable. (shrink)

Incidental perceptual memory tests reveal priming when words are generated orally from a semantic cue at study, and this priming could reflect contamination by voluntary retrieval. We tested this hypothesis using a generate condition and two read conditions that differed in depth of processing (read-phonemic vs read-semantic). An intentional word-stem completion test showed an advantage for the read-semantic over the generate condition and an advantage for the generate over the read-phonemic condition, and completion times were longer than in a control (...) test, prior to which there was no study phase. An incidental word-stem completion test showed equivalent priming for the read-semantic and read-phonemic study conditions, despite considerable power, and completion times were no longer than control, indicating that retrieval was involuntary, and insensitive to prior conceptual processing. The generate condition produced less priming than the read conditions, but significant priming nonetheless. The results show that priming from generating can be involuntary and suggest that lexical processes are responsible. They are also the first results conjointly showing a crossed double dissociation, a single dissociation, and a parallel effect across memory tests with identical physical retrieval cues. (shrink)

Although Sign Languages are gestural languages, the fact remains that some linguistic information can also be conveyed by spoken components as mouthing. Mouthing usually tend to reproduce the more relevant phonetic part of the equivalent spoken word matching with the manual sign. Therefore, one crucial issue in sign language is to understand whether mouthing is part of the signs themselves or not, and to which extent it contributes to the construction of signs meaning. Another question is to know whether mouthing (...) patterns constitute a phonological or a semantic cue in the lexical sign entry. This study aimed to investigate the role of mouthing on the processing of lexical signs in French Sign Language (LSF), according the type of bilingualism (intramodal vs. bimodal). For this purpose, a behavioral sign-picture lexical decision experiment was designed. Intramodal signers (native deaf adults) and Bimodal signers (fluent hearing adults) have to decide as fast as possible whether a picture matched with the sign seen just before. Five experimental conditions in which the pair sign-mouthing were congruent or incongruent were created. Our results showed a strong interference effect when the sign-mouthing matching was incongruent, reflected by higher error rates and lengthened reaction times compared with the congruent condition. This finding suggests that both groups of signers use the available lexical information contained in mouthing during accessing the sign meaning. In addition, deaf intramodal signers were strongly interfered than hearing bimodal signers. Taken together, our data indicate that mouthing is a determining factor in LSF lexical access, specifically in deaf signers. (shrink)

This article attempts to outline the contours of a transcendental phenomenology that would retain the intuition of a healthy realism. In this connection it is proposed to reinterpret the Husserlian notion of constitution, presenting constitution as a discover of reality. A distinction is made between strong and weak versions of constitution. It is constitution in the weak sense that combines, in our opinion, with the realist attitude. In order to achieve the above-mentioned goal (to present constitution as discovery), the Husserlian (...) notion of object sense is clarified: it is excluded as a representative or substitute of an intentional object; object sense is seen as a mode of givenness, as а medium by means of which the object is implied or given. The idea of a meaningful discovery of reality is best matched by this treatment of object meaning. It is thus possible to combine the realist attitude with the idea of meaningful access to the real, thus avoiding, on the one hand, naive realism and, on the other hand, transcendental-idealist implications. The Husserlian notion of constitution is further related with the idea of forming interpretative schemes of understanding the world, which may include political agendas, scientific paradigms, systems of speculative metaphysics, and religious faith. It is emphasized that, although the rejection of interpretation is impossible, interpretive schemes must be reconciled with real facts and events in order to “fine-tune” reason and reality. Finally, a separation is undertaken with the conception of J.- L. Marion, which relies on the deflation of meaning in favor of the given as such, calling into question the status of man as a being who possesses reason, who discovers reality and constitutes its meaning.

Humans can understand thousands of abstract words, even when they do not have clearly perceivable referents. Recent views highlight an important role of social experience in grounding of abstract concepts and sub-kinds of abstract concepts, but empirical work in this area is still in its early stages. In the present study, a picture-word semantic priming paradigm was employed to investigate the contribution effect of social experience that is provided by real-life pictures to social abstract concepts and emotional abstract concepts. Using (...) a lexical decision task, we examined responses to picture-SA word pairs and picture-EA word pairs in social/emotional semantically related and unrelated conditions. All pairs shared either positive or negative valence. The results showed quicker responses to positive SA and EA words that were preceded by related vs. unrelated prime pictures. Specifically, positive SA words were facilitated by the corresponding social scene pictures, whereas positive EA words were facilitated by pictures depict the corresponding facial expressions and gestures. However, such facilitatory effect was not observed in negative picture-SA/EA word conditions. This pattern of results suggests that a facilitatory effect of social experience on abstract concepts varies with different sub-kinds of abstract concepts, that seems to be limited to positive SA concepts. Overall, our findings confirm the crucial role of social experience for abstract concepts and further suggest that not all abstract concepts can benefit from social experience, at least in the semantic priming.

Sleep spindles are frequently studied for their relationship with state and trait cognitive variables, and they are thought to play an important role in sleep-related memory consolidation. Due to their frequent occurrence in NREM sleep, the detection of sleep spindles is only feasible using automatic algorithms, of which a large number is available. We compared subject averages of the spindle parameters computed by a fixed frequency (11-13 Hz for slow spindles, 13-15 Hz for fast spindles) automatic detection algorithm and the (...) individual adjustment method (IAM), which uses individual frequency bands for sleep spindle detection. Fast spindle duration and amplitude are strongly correlated in the two algorithms, but there is little overlap in fast spindle density and slow spindle parameters in general. The agreement between fixed and manually determined sleep spindle frequencies is limited, especially in case of slow spindles. This is the most likely reason for the poor agreement between the two detection methods in case of slow spindle parameters. Our results suggest that while various algorithms may reliably detect fast spindles, a more sophisticated algorithm primed to individual spindle frequencies is necessary for the detection of slow spindles as well as individual variations in the number of spindles in general.

This article presents a meta-analysis of the impact of minimal exposure to affective stimuli on the emergence of enduring conscious affective feelings. Theories often assume that such affective feelings are linked to automatic appraisals of events (i.e. in the absence of an evaluative processing goal). However, few studies have tested this hypothesis. Moreover, they have provided divergent results. We propose a meta-analysis of these studies to get a clearer picture on this issue. The meta-analysis includes 22 studies (37 effect sizes; (...) combined N = 2159) in which participants were repeatedly exposed to affective stimuli in the absence of an evaluative processing goal before their mood was measured. In this analysis, we focused on the type of stimulus presentation (i.e. visible vs. masked) as well as on the type of stimulus (i.e. faces, pictures, words). The results indicate that the effect of a stimulus is moderated by the visibility of the stimuli. Repeated exposure to visible stimuli leads to congruency effects (i.e. positive stimuli lead to positive feelings), whereas exposure to masked stimuli leads to contrast effects (i.e. positive stimuli lead to negative feelings). Moreover, these effects seem to be restricted to some types of stimuli, with no detectable effects of emotional faces. (shrink)

This paper briefly reviews the papers in this special section of HCA and makes the point—a point which should be obvious—that statistics are useful only as guidelines but tell one nothing about the individual patient in front of you. Chronological age merely shows what is true of most but decidedly not of all patients in a particular age group. To ration on the basis of age alone is unfair to the individual denied treatment and damaging to the community because it (...) disturbs the solidarity which comes about because most members of the community feel that the community has obligations beyond those of not directly harming them; indeed, what produces solidarity is the feeling that members of a community will do their best to come to each others help. Rationing on the basis of age alone denies people of equal treatment under the law and—when it comes to the elderly—is a type of age discrimination. It is pointed out that what matters is a patient’s disease and not his/her age. A permanently vegetative person 8 years of age is a much sadder occurrence than it would be at age 90—but the critical fact is that both are permanently vegetative. Age cuts both ways—it is irrational to spend hundreds of thousands of dollars, untold amounts of time, energy and devotion to the 520 gm infant with a gr IV diffuse haemorrhage whose chance of leading a sentient life is close to zero and to hesitate before using a diagnostic MRI on a patient who is 90 but fully alert and enjoying life. It is concluded that age as an independent variable in the allocation of resources is ethically highly problematic. (shrink)

This research examines the impact of implicit religious beliefs on work ethic in specific cultural contexts. Based on three studies, the authors found that thoughts related to religion impact work ethic, but only when the culture embraces religious values at work and in public environments. In a comparative setting, Moroccan participants primed with religious thoughts displayed greater work ethic, whereas similarly primed French participants exhibited less work ethic (Study 1). For North African–French biculturals, religious stimuli interacted with cultural (...) identity to predict work ethic (Study 2) and activated religious beliefs and cultural identity had a significant effect on their level of effort (Study 3). Our research reveals that implicit religious beliefs can predict work ethic in a manner contingent on a cultural setting. In cultures where religious values are historically embraced and encouraged, work ethic constitutes a religious construct that enhances work ethic. Conversely, in secular cultures, religious cues inhibit work ethic. We believe that within a multi-cultural, multi-religion work force, it is important to take note of these influences. (shrink)

The optical revolution, that is, the replacement of corpuscular optics by wave optics at the beginning of the nineteenth century, has attracted the attention of philosophers of science for a long time. For a long period the cause of the optical revolution was attributed to “crucial experiments” such as Foucault’s experiment on the velocity of light (Sabra 1954, pp.149-51). Later Frankel argued that social and political factors were necessary for the victory of the wave theory (Frankel 1976, p.142). These accounts, (...) however, were severely criticized by recent theorists of scientific change, especially Lakatos and Laudan. Lakatos calls the opinion that accounted for the optical revolution solely by “crucial experiments” naive “instant rationality” (Lakatos 1978, p.68 & 72n). Laudan also regards the attempt to explain scientific revolution mainly by social and political elements as “jumping to a premature conclusion” (Laudan 1977, p.4). (shrink)

Many philosophical debates take for granted that there is such a thing as ‘the’ common-sense conception of the phenomenon of interest. Debates about the nature of perception tend to take for granted that there is a single, coherent common-sense conception of vision, consistent with Direct Realism. This conception is often accorded an epistemic default status. We draw on philosophical and psychological literature on naïve theories and belief fragmentation to motivate the hypothesis that untutored common sense encompasses conflicting Direct Realist (...) and Indirect Realist conceptions: there is no such thing as ‘the’ common-sense conception of vision that could enjoy epistemic default status. To examine this hypothesis, a survey administered an agreement rating task with verbal and pictorial stimuli to lay participants. We found many laypeople simultaneously hold conflicting Direct Realist and Indirect Realist beliefs about vision. Against common assumptions, Direct Realist beliefs are not clearly dominant, and consistent adherence to Direct Realism is not the norm, but the exception. These findings are consistent with recent accounts of belief fragmentation. They forcefully challenge common methodology in philosophical debates about the nature of perception and beyond. (shrink)

Perception is conscious: perceiving involves a first-person experience of what’s perceived. It’s widely held that these perceptual experiences are independent of what's perceived. Viewing two visually indiscriminable #2 pencils would involve the same experience, despite viewing different objects. It’s also widely held that conscious perception enables thinking about what's perceiving. When you see one of those pencils you can think, THAT is a pencil. Some philosophers, including John McDowell and John Campbell, have suggested that these two features engender a puzzle: (...) how can perceptual experiences make perceived objects available for thought when they’re independent of those objects? This dissertation is a collection of four papers which address this question. -/- The first (chapter 2) argues that, under two minimal assumptions, conscious perception makes objects available for thought only if experience is not object independent. The second (chapter 3) argues that conscious perception makes objects available for thought by enabling voluntarily attention to them. The third (chapter 4) integrates empirical work on multiple-object tracking and philosophical work on attention to argue that conscious perception isn’t mediated by the construction of representations within the visual system. The fourth (chapter 5) uses philosophical methods and neurophysiology to give an account of the role of experience itself in how perception makes objects available for thought. A concluding chapter combines and extends results from the previous chapters to give a naive realist (vs representationalist) account of perceptual experience. -/- The questions about perceptual experience addressed in this dissertation (object dependent or independent? naive realist or representationalist?) are fundamental to our understanding of experience. Not only do they get at its basic nature, but their answers constrain how we might give scientifically respectable, or naturalistic, explanations of experience as well as how we might explain perceptual hallucinations and illusions.

Discusses recent work on representationalism, including: the case for a representationalist theory of consciousness, which explains consciousness in terms of content; rivals such as neurobiological type-type identity theory (Papineau, McLaughlin) and naive realism (Allen, Campbell, Brewer); John Campbell and David Papineau's recent objections to representationalism; the problem of the "laws of appearance"; externalist vs internalist versions of representationalism; the relation between representationalism and the mind-body problem.

When people are engaged in social interaction, they can repeat aspects of each other’s communicative behavior, such as words or gestures. This kind of behavioral alignment has been studied across a wide range of disciplines and has been accounted for by diverging theories. In this paper, we review various operationalizations of lexical and gestural alignment. We reveal that scholars have fundamentally different takes on when and how behavior is considered to be aligned, which makes it difficult to compare findings and (...) draw uniform conclusions. Furthermore, we show that scholars tend to focus on one particular dimension of alignment (traditionally, whether two instances of behavior overlap in form), while other dimensions remain understudied. This hampers theory testing and building, which requires a well‐defined account of the factors that are central to or might enhance alignment. To capture the complex nature of alignment, we identify five key dimensions to formalize the relationship between any pair of behavior: time, sequence, meaning, form, and modality. We show how assumptions regarding the underlying mechanism of alignment (placed along the continuum of priming vs. grounding) pattern together with operationalizations in terms of the five dimensions. This integrative framework can help researchers in the field of alignment and related phenomena (including behavior matching, mimicry, entrainment, and accommodation) to formulate their hypotheses and operationalizations in a more transparent and systematic manner. The framework also enables us to discover unexplored research avenues and derive new hypotheses regarding alignment. (shrink)

Building on findings that self-uncertainty motivates attempts to restore certainty about the self, particularly in ways that highlight one’s distinctiveness from others, we show that self-uncertainty, relative to uncertainty in general, increases creative generation among individualists. In Studies 1 to 3, high (but not low) individualists performed better on a creative generation task after being primed with self-uncertainty as opposed to general uncertainty. In Study 4, this effect emerged only among those who were told that the task measured creative (...) as opposed to analytical thinking, suggesting that the positive effects of self-uncertainty on performance are specific to tasks that bolster perceptions of uniqueness. In Study 5, self-uncertain individualists experienced a restoration of self-clarity after being induced to think about themselves as more (vs. less) creative. Implications for compensatory responses to self-uncertainty and factors that influence creativity are discussed. (shrink)

Voluntary simplicity (VS) refers to a minimalistic lifestyle of conscious, ecological, and ethical consumption, which is conducive to individual, societal, and environmental well-being. For policymakers and business managers, a key to leveraging this consumer shift is to promote persuasive appeals effectively. This research theorizes that the two forms of VS appeals are systematically associated with distinct temporal landmarks. In particular, we demonstrate that consumers are more likely to engage in biospheric voluntary simplicity (BVS) when priming a temporal landmark as the (...) start of a time period. In contrast, consumers are more likely to participate in egoistic voluntary simplicity (EVS) when priming a temporal landmark as the end of a time period. Notably, the matching effects are driven by distinct mechanisms, such that the effect of a match between a start temporal landmark and BVS appeals is driven by self-transcendence, whereas the effect of a match between an end temporal landmark and EVS appeals is motivated by self-enhancement. Beyond their substantive theoretical significance, our findings provide marketing campaigns with tools to enact strategies that support voluntary simplicity. (shrink)

The use of fictional models is extensive and rewarding in modern science. This fact captured the attention of philosophers of science, who are focusing on questions such as the following: is it possible for a fictional model to be explanatory? And, if so, in virtue of what is such a fictional model explanatory? In this paper, I discuss these questions in relation to the realism vs. anti-realism debate in philosophy of science. I focus on work developed by Alisa Bokulich who (...) has argued for the explanatory role played by fictional models, claiming that it can be accommodated by realism in ‘a broad sense’. To this end, Bokulich introduced what she called ‘an eikonic conception’ of explanation, as opposed to the so-called ‘ontic’ conception. This move, Bokulich claims, allows non-causal explanations to be acceptable to a modified version, as opposed to a ‘naïve’ brand of realism. Roughly, a fictional model can capture aspects of reality if it manages to act as a proxy for a theory targeting a physical system. As Bokulich explains with the example of James Clerk Maxwell’s use of mechanical models, this is due to structural correspondences between a model and a theory at a certain level of abstraction. However, Bokulich does not explain how the model grasps reality. In this paper, I fill this missing piece of the puzzle. While I agree with Bokulich on the explanatory function of fictional models, I shall invoke her reading of Maxwell’s work to draw a different conclusion. Specifically, I argue that structural correspondences at various levels form what I call ‘a ladder of abstractions’ which connects aspects of a target system to the corresponding depths of descriptions. Modifying in these terms the scope of ‘representing a system’, I suggest that Bokulich’s proposed modification of realism is obviated. (shrink)

What is it that semanticists think they are doing when using formalisation? What kind of endeavour is the formal semantics of natural language: scientific; linguistic; philosophical; logical; mathematical? If formal semantics is a scientific endeavour, then there ought to be empirical criteria for determining whether such a theory is correct, or an improvement on an alternative account. The question then arises as to the nature of the evidence that is being accounted for. It could be argued that the empirical questions (...) are little different in kind to other aspects of linguistic analysis, involving questions of performance and competence (Chomsky 1965; Saussure 1916). But there are aspects of formal accounts of meaning that appear to sit outside this scientific realm. One key issue concerns the precise nature of the formalisation that is adopted; what criteria are to be used to decide between accounts that are founded on different formal systems, with different ontological assumptions? Indeed, is it necessary to judge semantic frameworks on such grounds? In other words, are two theoretical accounts to be treated as equivalent for all relevant purposes if they account for exactly the same linguistic data? Broadly speaking, there are two related perspectives on the analysis of propositional statements, one “truth conditional” — reducing sentence meaning to the conditions under which the sentence is judged to be true (e.g. Montague 1973) — the other “proof theoretic” — reducing sentence meanings to patterns of entailments that are supported (e.g. Ranta 1994, Fox & Lappin 2005 ,Fox 2000). Variations of these perspectives might be required in the case of non-assertoric utterances. We may wonder what critieria might be used to decide between these approaches. This brings us back to the nature of the data itself. If the data is (merely) about which arguments, or truth conditions, subjects agree with, and which they disagree with, then the terms in which the theory is expressed may be irrelevant. But it may also be legitimate to be concerned with either (a) the intuitions that people have when reasoning with language, or (b) some technical or philosophical issues relating to the chosen formalism. The truth-conditional vs proof-theoretic dichotomy might broadly be characterised as model-theoretic vs axiomatic, where the model-theoretic tend to be built around a pre-existing formal theory, and the axiomatic involves formulating rules of behaviour “from scratch”. In some sense, fitting an analysis of a new problem into an existing framework could be described as providing some kind of “explanatory” power, assuming that the existing framework has some salient motivation that is independent of the specific details of the phenomena in question. In contrast, building a new theory that captures the behaviour might then be characterised as “descriptive”, as — superficially at least — it does not show how an existing theory “already” accounts for the data in some sense. Here we observe instead that the argument can be run in the other direction. that a reductive model-theoretic account merely “describes” how some aspects of a problem can be reduced to some formalisation, but may fail to capture a subject’s understanding or intuitions about meaning. It is surely appropriate for the formal theory itself to be at least sympathetic to the ontological concerns and intuitions of its subjects — if not inform them (Dummett 1991). The alternative amounts to little more than carving out otherwise arbitrary aspects of a system that mimics the required behaviour, without a coherent explanation of why some aspects of a formal theory characterise, or capture, the intended meaning, but not others (cf. Benacerraf 1965). That seems an impoverished approach, weakening any claim to “explain”. Any constraint this imposes on what is it to be an explanatory account of meaning then faces the same problem as naive notions of compositionality (Zadrozny 1994) — that is, what appears to be a meaningful restriction is, in reality, a mirage.

Being and Value collects together fifteen essays by Nicholas Rescher on salient issue in metaphysics, axiology and metaphilosophy. In the way in which they shed new light on significant philosophical issues, these deliberations are emblematic of Rescher s characteristic way of illuminating timeless issues and historical perspectives in a reciprocal interrelationship. The chapter of the book are as follows: Being and Value: On the Prospect of Optimalism; On Evolution and Intelligent Design; Mind and Matter; Fallacies Regarding Free Will; Sophisticating Naive (...) Realism; Taxonomic Complexity and the Laws of Nature; Practical Vs. Theoretical Reason; Pragmatism as a Growth Industry; Cost Benefit Epistemology; Quantifying Quality; Explanatory Surdity; Can Philosophy be Objective?; On Ontology in Cognitive Perspective; Plenum Theory [Essay Written Jointly with Patrick Grim]; and Onometrics (On Referential Analysis in Philosophy)".

Although lay notions in normative ethics have previously been investigated within the framework of the dual-process interpretation of the terror management theory (TMT), meta-ethical beliefs (subjective vs. objective morality) have not been previously investigated within the same framework. In the present research, we primed mortality salience, shown to impair reasoning performance in previous studies, to see whether it inhibits subjectivist moral judgments in three separate experiments. In Experiment 3, we also investigated whether impaired reasoning performance indeed mediates the effect (...) of mortality salience on subjectivism. The results of the three experiments consistently showed that people in the mortality salience group reported significantly less subjectivist responses than the control group, and impaired reasoning performance partially mediates it. Overall, the results are consistent with the dual-process interpretation of TMT and suggest that not only normative but also meta-ethical judgments can be explained by this model. (shrink)

Next SectionBackground Scientific papers are retracted for many reasons including fraud (data fabrication or falsification) or error (plagiarism, scientific mistake, ethical problems). Growing attention to fraud in the lay press suggests that the incidence of fraud is increasing. Methods The reasons for retracting 742 English language research papers retracted from the PubMed database between 2000 and 2010 were evaluated. Reasons for retraction were initially dichotomised as fraud or error and then analysed to determine specific reasons for retraction. Results Error was (...) more common than fraud (73.5% of papers were retracted for error (or an undisclosed reason) vs 26.6% retracted for fraud). Eight reasons for retraction were identified; the most common reason was scientific mistake in 234 papers (31.5%), but 134 papers (18.1%) were retracted for ambiguous reasons. Fabrication (including data plagiarism) was more common than text plagiarism. Total papers retracted per year have increased sharply over the decade (r=0.96; p<0.001), as have retractions specifically for fraud (r=0.89; p<0.001). Journals now reach farther back in time to retract, both for fraud (r=0.87; p<0.001) and for scientific mistakes (r=0.95; p<0.001). Journals often fail to alert the naïve reader; 31.8% of retracted papers were not noted as retracted in any way. Conclusions Levels of misconduct appear to be higher than in the past. This may reflect either a real increase in the incidence of fraud or a greater effort on the part of journals to police the literature. However, research bias is rarely cited as a reason for retraction. (shrink)

Much attention has recently been paid to the idea, which I label ‘External World Acquaintance’ (EWA), that the phenomenal character of perceptual experience is partially constituted by external features. One motivation for EWA which has received relatively little discussion is its alleged ability to help deal with the ‘Explanatory Gap’ (e.g. Fish 2008, 2009, Langsam 2011, Allen 2016). I provide a reformulation of this general line of thought, which makes clearer how and when EWA could help to explain the specific (...) phenomenal nature of visual experience. In particular, I argue that by focusing on the different kinds of perceptual actions that are available in the case of visual spatial vs. colour perception, we get a natural explanation for why we should expect the specific nature of colour phenomenology to remain less readily intelligible than the specific nature of visual spatial phenomenology.

Many cognitive and evolutionary theories of religion argue that supernatural explanations are byproducts of our cognitive adaptations. An influential argument states that our supernatural explanations result from a tendency to generate anthropomorphic explanations, and that this tendency is a byproduct of an error management strategy because agents tend to be associated with especially high fitness costs. We propose instead that anthropomorphic and other supernatural explanations result as features of a broader toolkit of well-designed cognitive adaptations, which are designed for explaining (...) the abstract and causal structure of complex, unobservable, and uncertain phenomena that have substantial impacts on fitness. Specifically, we argue that (1) mental representations about the abstract vs. the supernatural are largely overlapping, if not identical, and (2) when the data-generating processes for scarce and ambiguous observations are complex and opaque, a naive observer can improve a bias-variance trade-off by starting with a simple, underspecified explanation that Western observers readily interpret as “supernatural.” We then argue that (3) in many cases, knowledge specialists across cultures offer pragmatic services that involve apparently supernatural explanations, and their clients are frequently willing to pay them in a market for useful and effective services. We propose that at least some ethnographic descriptions of religion might actually reflect ordinary and adaptive responses to novel problems such as illnesses and natural disasters, where knowledge specialists possess and apply the best available explanations about phenomena that would otherwise be completely mysterious and unpredictable.

This is a general account of metavaluations and their applications, which can be seen as an alternative to standard model-theoretic methodology. They work best for what are called metacomplete logics, which include the contraction-less relevant logics, with possible additions of Conjunctive Syllogism, & →.A→C, and the irrelevant, A→.B→A, these including the logic MC of meaning containment which is arguably a good entailment logic. Indeed, metavaluations focus on the formula-inductive properties of theorems of entailment form A→B, splintering into two types, M1- (...) and M2-, according to key properties of negated entailment theorems. Metavaluations have an inductive presentation and thus have some of the advantages that model theory does, but they represent proof rather than truth and thus represent proof-theoretic properties, such as the priming property, if ├ A $\vee$ B then ├ A or ├ B, and the negated-entailment properties, not-├ ∼ and ├ ∼ iff ├ A and ├ ∼ B. Topics to be covered are their impact on naive set theory and paradox solution, and also Peano arithmetic and Godel’s First and Second Theorems. Interesting to note here is that the familiar M1- and M2-metacomplete logics can be used to solve the set-theoretic paradoxes and, by inference, the Liar Paradox and key semantic paradoxes. For M1-logics, in particular, the final metavaluation that is used to prove the simple consistency is far simpler than its correspondent in the model-theoretic proof in that it consists of a limit point of a single transfinite sequence rather than that of a transfinite sequence of such limit points, as occurs in the model-theoretic approach. Additionally, it can be shown that Peano Arithmetic is simply consistent, using metavaluations that constitute finitary methods. Both of these results use specific metavaluational properties that have no correspondents in standard model theory and thus it would be highly unlikely that such model theory could prove these results in their final forms.

Howard argues that the existence of unitarily inequivalent representations in Quantum Field Theory presents a problem for structural realism in this context. I consider two potential ways round this problem: 1), follow Wallace in adopting the 'naive' Lagrangian form of QFT with cut-offs; 2), adapt Ruetsche's 'Swiss Army Knife' approach. The first takes us into the current debate between Wallace and Fraser on conventional vs. algebraic QFT. The second involves consideration of the role of inequivalent representations in understanding spontaneous symmetry (...) breaking and quantum statistics. In both cases, I suggest, the structural realist has sufficient room to manoeuvre. (shrink)

This article investigates account episodes in Italian family dinner conversations and illustrates how sequential patterns and participation are organized in terms of preferences indexical of moral ideology and moral order. Accounts have been mostly examined as speech acts abstracted from embedding sequential environment; this article shows that different design features of the priming move in account episodes retrospectively define different aspects of a situation as problematic and prospectively activate the relevance for distinctive remedial moves. On an ideological level, narrative elicitations (...) as priming moves and accounts as remedial moves index a moral perspective that promotes moral reasoning and thus the negotiation of norms. In addition, such moves realize a practice of morality that tends to be inquisitory vs condemnatory, offering the benefit of the doubt prior to guilt allocation. In conclusion, the discursive mechanics of accountability constitutes a medium for reproduction of, and innovation in, the moral order. (shrink)

We examine Paul Halmos’ comments on category theory, Dedekind cuts, devil worship, logic, and Robinson’s infinitesimals. Halmos’ scepticism about category theory derives from his philosophical position of naive set-theoretic realism. In the words of an MAA biography, Halmos thought that mathematics is “certainty” and “architecture” yet 20th century logic teaches us is that mathematics is full of uncertainty or more precisely incompleteness. If the term architecture meant to imply that mathematics is one great solid castle, then modern logic tends to (...) teach us the opposite lesson, namely that the castle is floating in midair. Halmos’ realism tends to color his judgment of purely scientific aspects of logic and the way it is practiced and applied. He often expressed distaste for nonstandard models, and made a sustained effort to eliminate first-order logic, the logicians’ concept of interpretation, and the syntactic vs semantic distinction. He felt that these were vague, and sought to replace them all by his polyadic algebra. Halmos claimed that Robinson’s framework is “unnecessary” but Henson and Keisler argue that Robinson’s framework allows one to dig deeper into set-theoretic resources than is common in Archimedean mathematics. This can potentially prove theorems not accessible by standard methods, undermining Halmos’ criticisms. (shrink)
