Research on the neurobiology and psychosocial features of Major Depressive Disorder has the ability to extend our understanding of affiliative behavior. In depression, decreased hedonic capacity and hypoactivity in dopaminergic and prefrontal circuitries may decrease the ability to experience affiliative relationships as rewarding. We suggest that neurobiological research on depression can provide a test case for theoretical models of affiliation.

Optimization models have often been useful in attempting to understand the adaptive significance of behavioral traits. Originally such models were applied to isolated aspects of behavior, such as foraging, mating, or parental behavior. In reality, organisms live in complex, ever-changing environments, and are simultaneously concerned with many behavioral choices and their consequences. This target article describes a dynamic modeling technique that can be used to analyze behavior in a unified way. The technique has been widely used in (...) class='Hi'>behavioral studies of insects, fish, birds, mammals, and other organisms. The models use biologically meaningful parameters and variables, and lead to testable predictions. Limitations arise because nature's complexity always exceeds our modeling capacity. (shrink)

Working memory limits are best defined in terms of the complexity of the relations that can be processed in parallel. Complexity is defined as the number of related dimensions or sources of variation. A unary relation has one argument and one source of variation; its argument can be instantiated in only one way at a time. A binary relation has two arguments, two sources of variation, and two instantiations, and so on. Dimensionality is related to the number of chunks, because (...) both attributes on dimensions and chunks are independent units of information of arbitrary size. Studies of working memory limits suggest that there is a soft limit corresponding to the parallel processing of one quaternary relation. More complex concepts are processed by or In segmentation, tasks are broken into components that do not exceed processing capacity and can be processed serially. In conceptual chunking, representations are to reduce their dimensionality and hence their processing load, but at the cost of making some relational information inaccessible. Neural net models of relational representations show that relations with more arguments have a higher computational cost that coincides with experimental findings on higher processing loads in humans. Relational complexity is related to processing load in reasoning and sentence comprehension and can distinguish between the capacities of higher species. The complexity of relations processed by children increases with age. Implications for neural net models and theories of cognition and cognitive development are discussed. (shrink)

In this paper, I argue that recent sociological theory has become increasingly bifurcated into two mutually incompatible styles of theorizing that I label formalist and behavioral-realist. Formalism favors mathematization and proposes an instrumentalist ontology of abstract processes while behavioral-realist theory takes at its basis the "real" physical individual endowed with concrete biological, cognitive and neurophysiological capacities and constraints and attempts to derive the proper conceptualization of social behavior from that basis. Formalism tends to lead toward a conceptually (...) independent sociology that in principle requires only minimal reference to the empirical and ontological storehouse of other disciplines, while behavioral-realist theory leads to an interdisciplinary sociology that can be located within a hierarchy of behavioral sciences, leading to questions regarding the relationship between sociology and other disciplines as well as issues of transdisciplinary unification and possible interdisciplinary reduction. I explore the consequences of this split for the project of explanatory sociological theory within the context of how it has manifested itself in sociological network theory and social psychology. I close with a critique and assessment of formalist tendencies in sociological theorizing. (shrink)

Drawing on behavioral economics, nudges (policy interventions based on choice architecture) have the capacity to strategically shape policymaking, subtly guiding individual behavior by adjusting their decision environment. Applied to enhance vaccinations, boost retirement savings, or promote healthy habits, these interventions align with consensus-defined well-being. As governments adopt nudges, scholars have explored their role in fostering virtues. This paper argues that nudges have the potential to efficiently contribute to virtuous development by instilling and sustaining habits, respecting individual choice, and ensuring (...) deliberation. It introduces the concept of virtue nudges, emphasizing the alignment of habits with virtues for targeted behavioral change and the formation of morally virtuous habits. (shrink)

Recent research has demonstrated that word learners can determine word-referent mappings by tracking co-occurrences across multiple ambiguous naming events. The current study addresses the mechanisms underlying this capacity to learn words cross-situationally. This replication and extension of Yu and Smith (2007) investigates the factors influencing both successful cross-situational word learning and mis-mappings. Item analysis and error patterns revealed that the co-occurrence structure of the learning environment as well as the context of the testing environment jointly affected learning across observations. Learners (...) also adopted an exclusion strategy, which contributed conjointly with statistical tracking to performance. Implications for our understanding of the processes underlying cross-situational word learning are discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Appreciating Anorexia:Decisional Capacity and the Role of ValuesThomas Grisso (bio) and Paul S. Appelbaum (bio)Keywordscompetence, consent, anorexia, appreciation, decision makingTan and her colleagues (2006) reported that persons with anorexia nervosa typically manifest no difficulty satisfying the criteria for abilities associated with competence to consent to or refuse treatment. Their results led them to conclude that these patients generally had no problem grasping the nature of anorexia and its possible (...) consequences (understanding), typically did not have difficulty processing information when making treatment decisions (reasoning), and usually neither denied that they had a disorder nor manifested distorted beliefs about the potential consequences of treatment for the disorder.Nevertheless, these authors found, some anorexia patients said that they knew they might die and that they would rather die than suffer the alternative consequences (e.g., loss of identity, feeling of being disgusting). They point out that these beliefs, suggesting questionable competence, were not identified by the usual criteria for competence to consent to treatment. Therefore, they propose that we should consider a modification of the criteria for competence to consent to treatment. They argue for inclusion of "pathological values" as the basis for a finding of incompetence. Their notion of a pathological value (as we summarize it based on their Discussion) includes (a) a personal value (b) on which treatment refusal is based, that (c) is not authentic, and (d) is due to a mental disorder.Second, Tan and colleagues were concerned that the MacArthur Competence Assessment Tool for Treatment (MacCAT-T), currently used widely to assess competence to consent to treatment, did not seem to take values into account when examining deficits related to lack of appreciation or reasoning. They point out that most patients with anorexia nervosa in their study had "pathological values" that influenced their thinking about treatment, yet they did not obtain poor scores on the instrument's appreciation scale, which assesses whether patients deny that they have the illness or offer reasons for accepting or refusing treatment that are based on delusional premises or a serious distortion of reality. Moreover, almost all of the anorexia patients in the study obtained adequate scores on reasoning, which examines the ability to process options and consequences when weighing a treatment decision. [End Page 293]Reasons for Caution in Altering Criteria for CompetenceA fundamental step in considering Tan and her co-worker's proposal is to examine whether it is necessary to add a concept of "pathological values" to the legal construct of competence to consent to treatment. Modifying the legal doctrine of consent is important if that is needed to improve its validity or reliability. But modifications of the doctrine would have considerable costs, including a long process of producing logical and empirical evidence for its necessity, developing methods to assess the new concept, and then a process of debate, persuasion, and education to change laws, ethical guidelines, and medical training. Moreover, principles of theory building urge parsimony. A theory should employ no more concepts or assumptions than are required to account for the phenomena that the theory seeks to organize or explain. So one must be sure that modifications are truly necessary before adding complexity to the theory of decisional competence.In addition, there is an inherent danger in altering a concept like competence to consent to treatment on the basis of the study of any one mental disorder. It is not at all clear how the modification might influence findings of competence when applied to other disorders. Using a study of patients with anorexia nervosa as the impetus for changing the competence concept runs this risk. For example, anorexia is one of a class of mental disorders that is characterized by a failure to abstain from behavior (here, limiting food intake and other behaviors designed to reduce weight) that has negative consequences for the person. Other conditions in this category might include substance abuse disorders and impulse control disorders (e.g., pathological gambling). Even if one concludes that revised criteria for competence would reduce false-positive findings of competence in this group of disorders, one would have to consider carefully its impact on the full range of disabling mental conditions.Moreover, the sensitivity...

The authors propose the integrity capacity construct with its four dimensions (process, judgment, development and system dimensions) as a framework for analyzing and resolving behavioral, moral and legal complexity in business ethics' issues at the individual and collective levels. They claim that moral progress in business comes about through the increase in stakeholders who regularly handle moral complexity by demonstrating process, judgment, developmental and system integrity capacity domestically and globally.

This excellent outline of evolutionary hypotheses is compromised by severe reductionism. Other writings succeed in granting theism ontological significance without compromising rigor. The discussion of counterintuitiveness neglects coherence in memory. Bearing in mind our severely limited working memory capacity, susceptibility to religious mythologies may comprise an adaptive heuristic approach to summarizing the contingencies of the most far-reaching of life's problems.

Physical and mental training are associated with positive effects on executive functions throughout the lifespan. However, evidence of the benefits of combined physical and mental regimes over a sedentary lifestyle remain sparse. The goal of this study was to investigate potential mechanisms, from a source-resolved event-related-potential perspective, that could explain how practicing long-term physical and mental exercise can benefit neural processing during the execution of an attention switching task. Fifty-three healthy community volunteers who self-reported long-term practice of Tai Chi, meditation (...) + exercise, simple aerobics, or a sedentary lifestyle, aged 47.8 ± 14.6 were included in this analysis. All participants undertook high-density electroencephalography recording during a switch paradigm. Our results indicate that people who practice physical and mental exercise perform better in a task-switching paradigm. Our analysis revealed an additive effect of the combined practice of physical and mental exercise over physical exercise only. In addition, we confirmed the participation of frontal, parietal and cingulate areas as generators of event-related-potential components commonly associated to the performance of switch tasks. Particularly, the N2-like component of the parietal and frontal domains showed significantly greater amplitudes in the exercise and mental training groups compared with aerobics and sedentary groups. Furthermore, we showed better performance associated with greater N2-like amplitudes. Our multivariate analysis revealed that activity type was the most relevant factor to explain the difference between groups, with an important influence of age, and body mass index, and with small effects of educational years, cardiovascular capacity, and sex. These results suggest that chronic combined physical and mental training may confer significant benefits to executive function in normally aging adults, probably through more efficient early attentional processing. Future experimental studies are needed to confirm our results and understand the mechanisms on parieto-frontal networks that contribute to the cognitive improvement associated with practicing combined mental and aerobic exercise, while carefully controlling confounding factors, such as age and body mass index.

Moral and legal responsibility is diminished in neuropsychiatric patients who lack the capacity to use reasoning to determine morally appropriate behavior. Patients with behavioral-variant frontotemporal dementia (bvFTD), however, develop immoral behaviors as a result of their disease despite the ability to explicitly state that their behavior is wrong. In order to determine whether bvFTD patients should be held responsible for their immoral behavior, we begin by discussing the philosophical concepts of free will, determinism, and responsibility. Those who believe in (...) both determinism and free will are called compatibilists. We argue that reason-responsiveness, a specific type of compatibilism, cannot fully determine responsibility in bvFTD patients if reason-responsiveness is considered to be a single, unified concept. Instead, we argue that several different neuropsychological capacities, including many that are impaired in bvFTD patients, contribute to a patient's ability to respond to certain reasons in specific situations. Finally, we propose a new framework for understanding reason-responsiveness, using case examples to illustrate how this model can be used to determine responsibility in neuropsychiatric patients.

There are legitimate worries about gaps between scientific evidence of brain states and function (for example, as evidenced by fMRI data) and legal criteria for determining criminal culpability. In this paper I argue that behavioral evidence of capacity, motive and intent appears easier for judges and juries to use for purposes of determining criminal liability because such evidence triggers the application of commonsense psychological (CSP) concepts that guide and structure criminal responsibility. In contrast, scientific evidence of neurological processes and (...) function – such as evidence that the defendant has a large brain tumor – will not generally lead a judge or jury to directly infer anything that is relevant to the legal determination of criminal culpability . (Vincent 2008) In these cases, an expert witness will be required to indicate to the fact-finder what this evidence means with regard to mental capacity; and then another inference will have to be made from this possible lack of capacity to the legal criteria for guilt, cast in CSP terms.<br><br>To reliably link evidence of brain function and structure and assessment of criminal responsibility, we need to re-conceptualize the mental capacities necessary for responsibility, particularly those that are recognized as missing or compromised by the doctrines of “legal capacity” (Hart 1968) and “diminished capacity.” I argue that formulating these capacities as executive functions within the brain can provide this link. I further claim that it would be extremely useful to consider evidence of executive function as related to the diminished capacity doctrine at sentencing. This is because it is primarily at this stage in criminal proceedings where the use of the diminished capacity doctrine is most prevalent, as evidenced by the recent Supreme Court cases of Atkins v. Virginia (536 U.S. 304 (2002)) and Roper v. Simmons (543 U.S. 551 (2005)).<br>. (shrink)

Cowan's review shows that a short-term memory limit of four items is consistent with a wide range of phenomena in the field. However, he does not explain that limit, whereas an existing theory does offer an explanation for capacity limitations. Furthermore, processing capacity limits cannot be reduced to storage limits as Cowan claims.

Until recently, economics conceived of poverty solely as a lack of material resources. This view likely captures the reality of poverty experienced by many people around the globe. However, two waves of behavioral economics demonstrate that the narrowing of people’s external environments may change people themselves: poverty lowers the quality of decision-making and poverty and oppression may depress the capacity to aspire. Poverty and a history of oppression also change how individuals are perceived. To overcome these effects may require (...) helping people acquire new mental models. This essay discusses key findings from behavioral economics, the implications for agency, and some interventions with promising outcomes. We hope to inspire scholars and policymakers to think more deeply about the nature of poverty and oppression and to consider policies that target the psychological and sociological factors that create cycles of poverty.

Adaptive training adjusts a training task with the goal of improving learning outcomes. Adaptive training has been shown to improve human performance in attention, working memory capacity, and motor control tasks. Additionally, correlations have been observed between neural EEG spectral features and the performance of some cognitive tasks. This relationship suggests some EEG features may be useful in adaptive training regimens. Here, we anticipated that adding a neural measure into a behavioral-based adaptive training system would improve human performance on (...) a subsequent transfer task. We designed, developed, and conducted a between-subjects study of 44 participants comparing three training regimens: Single Item Fixed Difficulty, Behaviorally Adaptive Training, and Combined Adaptive Training using both behavioral and EEG measures. Results showed a statistically significant transfer task performance advantage of the CAT-based system relative to SIFD and BAT systems of 6 and 9 percentage points, respectively. Our research shows a promising pathway for designing closed-loop BCI systems based on both users' behavioral performance and neural signals for augmenting human performance. (shrink)

Although discriminative deep neural networks are currently dominant in cognitive modeling, we suggest that capacity-limited, generative models are a promising avenue for future work.

With Jan Degenaar and Kevin O’Regan’s (D&O) critique of (what they call) ‘autopoietic enactivism’ as point of departure, this article seeks to revisit, refine, and develop phenomenology’s significance for the enactive view. Arguing that D&O’s ‘sensorimotor theory’ fails to do justice to perceptual meaning, the article unfolds by (1) connecting this meaning to the notion of enaction as a meaningful co-definition of perceiver and perceived, (2) recounting phenomenological reasons for conceiving of the perceiving subject as a living body, and (3) (...) showing how the phenomenological perspective does a better job at fulfilling D&O’s requirement for grounding notions of mentality in ‘outer’ criteria than they do. The picture that thus emerges is one of perceptual meaning as an integration of lived, living, and behavioral aspects – a structure of behavior that cannot be captured by appeal to sensorimotor capacities alone but that is adequately illuminated by the enactive notion of adaptive autonomy.

Finally, the (...) authors recommend two leadership practices to build competence in business leaders to enhance integrity capacity as an organizational strategic asset. (shrink)

Algorithms for approximate Bayesian inference, such as those based on sampling (i.e., Monte Carlo methods), provide a natural source of models of how people may deal with uncertainty with limited cognitive resources. Here, we consider the idea that individual differences in working memory capacity (WMC) may be usefully modeled in terms of the number of samples, or “particles,” available to perform inference. To test this idea, we focus on two recent experiments that report positive associations between WMC and two distinct (...) aspects of categorization performance: the ability to learn novel categories, and the ability to switch between different categorization strategies (“knowledge restructuring”). In favor of the idea of modeling WMC as a number of particles, we show that a single model can reproduce both experimental results by varying the number of particles—increasing the number of particles leads to both faster category learning and improved strategy‐switching. Furthermore, when we fit the model to individual participants, we found a positive association between WMC and best‐fit number of particles for strategy switching. However, no association between WMC and best‐fit number of particles was found for category learning. These results are discussed in the context of the general challenge of disentangling the contributions of different potential sources of behavioral variability. (shrink)

Using explicit memory measures, Cowan predicts a new circumstance in which the central capacity limit of 4 chunks should obtain. Supporting results for such an experiment, using continuous old-new recognition, are described. With implicit memory measures, Cowan assumes that short-term repetition priming reflects the central capacity limit. I argue that this phenomenon instead reflects limits within individual perceptual processing modules.

In the last 10 years, emotional intelligence has become a current issue of research in psychology, and there are indicators to consider that emotional intelligence should be analyzed to help the coach to behave effectively during competitions. According to Boardley’s (2018) revised model of coaching efficacy, coaches’ emotional intelligence is predictive of their efficacy beliefs, which, in turn, is predictive of coaching behavior. However, little is known about the mediating effects of coaching efficacy dimensions on the relationships between coach’s emotional (...) intelligence and reactive behaviors in competitive settings. Thus, the purpose of this study is to examine mediating effects of coaching efficacy dimensions on the relationship between emotional intelligence and coaches’ reactive behaviors during a game using a multimethod approach. Participants were 258 coaches of youth football players aged 9 to 17 years old. Observations in situ using Coaching Behavior Assessment System were carried on 258 football games during two seasons. At the end of each game, coaches completed the Wong and Law Emotional Intelligence Scale and the Coaching Efficacy Scale. Structural equation modelling analyses revealed that motivation efficacy and character building mediated the relationship between regulation of emotion and positive and negative coaches’ reactions during game. Specifically, motivation efficacy mediated the association between regulation of emotion and positive coaches’ reactions, and the relationship between regulation of emotion and negative coaches’ reactions were mediated by motivation efficacy and character building. In addition, coaching level moderated the relationships between emotional intelligence, self-efficacy and coaches’ reactive behaviors. Findings of the present study showed that coaching efficacy dimensions (i.e., motivation efficacy and character building) that have the capacity to influence their confidence in ability to affect the psychological mood and positive attitude of athletes, transfer the effects of emotional intelligence (i.e., regulation of emotion) on coaches’ verbal reactions during a youth soccer game. Specifically, a coach who feels competent to regulate their own emotions would perceive high beliefs of efficacy to motivate and to build character of their athletes, and this insight has an impact on their positive verbal reactions in response to athletes’ performances.

Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety of data on capacity limits suggesting that the smaller capacity limit is real. Capacity limits (...) will be useful in analyses of information processing only if the boundary conditions for observing them can be carefully described. Four basic conditions in which chunks can be identified and capacity limits can accordingly be observed are: (1) when information overload limits chunks to individual stimulus items, (2) when other steps are taken specifically to block the recoding of stimulus items into larger chunks, (3) in performance discontinuities caused by the capacity limit, and (4) in various indirect effects of the capacity limit. Under these conditions, rehearsal and long-term memory cannot be used to combine stimulus items into chunks of an unknown size; nor can storage mechanisms that are not capacity-limited, such as sensory memory, allow the capacity-limited storage mechanism to be refilled during recall. A single, central capacity limit averaging about four chunks is implicated along with other, noncapacity-limited sources. The pure STM capacity limit expressed in chunks is distinguished from compound STM limits obtained when the number of separately held chunks is unclear. Reasons why pure capacity estimates fall within a narrow range are discussed and a capacity limit for the focus of attention is proposed. Key Words: attention; enumeration; information chunks; memory capacity; processing capacity; processing channels; serial recall; short-term memory; storage capacity; verbal recall; working memory capacity.

In the biomedical and behavioral sciences, it is widely recognized that researchers conducting studies involving human participants must respect the autonomy of research subjects. There is significant debate in the clinical research ethics and bioethics literatures about what it means for an individual to be autonomous.

Ernst Mayr proposed a distinction between “proximate”, mechanistic, and “ultimate”, evolutionary, causes of biological phenomena. This dichotomy has influenced the thinking of many biologists, but it is increasingly perceived as impeding modern studies of evolutionary processes, including study of “niche construction” in which organisms alter their environments in ways supportive of their evolutionary success. Some still find value for this dichotomy in its separation of answers to “how?” versus “why?”questions about evolution. But “why is A?” questions about evolution necessarily take (...) the form “how does A occur?”, so this separation is illusory. Moreover, the dichotomy distorts our view of evolutionary causality, in that, contra Mayr, the action of natural selection, driven by genotype-phenotype-environment interactions which constitute adaptations, is no less “proximate” than the biological mechanisms which are altered by naturally selected genetic variants. Mayr’s dichotomy thus needs replacement by more realistic, mechanistic views of evolution. From a mechanistic viewpoint, there is a continuum of adaptations from those evolving as responses to unchanging environmental pressures to those evolving as the capacity for niche construction, and intermediate stages of this can be identified. Some biologists postulate an association of “phenotypic plasticity” (phenotype-environment covariation with genotype held constant) with capacity for niche construction. Both “plasticity” and niche construction comprise wide ranges of adaptive mechanisms, often fully heritable and resulting from case-specific evolution. Association of “plasticity” with niche construction is most likely to arise in systems wherein capacity for complex learning and behavioral flexibility have already evolved. (shrink)

Critical factors that appear to encourage vocal development in humans are altriciality and long immaturity.

Academic research studies examining the ethical attitudes and behaviors of salespeople have produced several frameworks that explore the ethical decision-making processes to which salespeople adhere when faced with ethical dilemmas.

Given the fact that individuals’ emotional capacities play an important role in decision-making when faced with an ethical dilemma, there is a need (...) for empirical research in this area. We address this issue by outlining and testing an emotion-based model to study the ethical attitudes and behaviors of salespeople in a relational selling context. Building on the cognitive-affective model proposed by Gaudine and Thorne (J Bus Ethics 31:175–187, 2001 ), we outline a framework that incorporates higher order prosocial emotions: capacity for concern and capacity for guilt. We include salesperson’s role clarity within the organization as a moderator to examine person–situation interaction. (shrink)

There is an impressive literature on organizational capacities that enable specific types of performance, but no work has been done on whether such capabilities extend to an organizational capacity for trustworthiness (CFT). This paper introduces the notion of a capacity for trustworthiness (CFT) defined as the collective capability of the organization to produce positive signals of trustworthiness to stakeholders. The antecedents to the CFT are bundles of organization routines that enable the firm to manifest trustworthiness and balance attending to (...) both financial and relational goals. The consequences of a high CFT are outcomes and behaviors that are congruent with pivotal stakeholder expectations and are, therefore, trust inducing. A process model is offered that outlines how an organization’s routines and CFT change in response to feedback and pressure and increase or decrease stakeholders’ trust. Implications for the management of stakeholder relations, trust repair, and the management of organizational systems are reviewed. (shrink)

Chimpanzee/human technological differences are vast, reflect multiple interacting behavioral processes, and may result from the increased information-processing and hierarchical mental constructional capacities of the human brain. Therefore, advanced social, technical, and communicative capacities probably evolved together in concert with increasing brain size. Interpretations of these evolutionary and species differences as continuities or discontinuities reflect differing scientific perspectives.

The phenomenon whereby severely disabled persons self-report a higher than expected level of subjective well-being is called the “disability paradox.” One explanation for the paradox among brain injury survivors is “response shift,” an adjustment of one’s values, expectations, and perspective in the aftermath of a life-altering, disabling injury. The high level of subjective well-being appears paradoxical when viewed from the perspective of the non-disabled, who presume that those with severe disabilities experience a quality of life so poor that it might (...) make their lives not worth living. This presumption has profound consequences, for it may inform end-of-life choices made in advance directives, or influence decisions made by surrogates on behalf of persons who are unable to direct their own medical treatment. -/- Peterson et al propose a cautious, well-considered plan to use fMRI-based brain-computer interfaces to assess the decision making capacity of covertly aware, behaviorally non-responsive individuals who retain high levels of preserved cognition. Their plan, if it succeeds, could eventually restore autonomy and empower some severely disabled persons, allowing them to participate in clinical decision making. Peterson et al discuss possible in-principle objections to their proposal, among them the “argument from psychological health,” and the “changing sets of values” objection. These objections both presume that deviations from a pre-injury norm could indicate diminished decision making capacity. This presumption threatens the autonomy of the patient who is capable of making decisions, but whose post-injury decisions appear to diverge from pre-injury preferences or values. In light of the potential for response shift, and the disability paradox, it should not be inferred that changes in values or preferences are unreflective of the true current preferences of a brain-injured person, nor are they conclusive evidence of diminished capacity. Presuming diminished capacity on the basis of unexpected or unconventional preferences has, in the past, been used to disempower patients whose autonomy and capacity would not have been doubted had they made choices that accorded with the expectations or values of others. We must be cautious, and vigilant, to prevent similarly diminishing the autonomy of covertly aware, behaviorally non-responsive individuals on the basis of empirically and ethically questionable inferences about their decision making capacity.

Humor and social dilemmas are two disparate areas that have been linked to emotions. However, they tend to have been studied apart from considerations of emotion and emotional expression.

Commentators expressed a wide variety of views on whether there is a basic capacity limit of 3 to 5 chunks and, among those who believe in it, about why it occurs. In this response, I conclude that the capacity limit is real and that the concept is strengthened by additional evidence offered by a number of commentators. I consider various arguments why the limit occurs and try to organize these arguments into a conceptual framework or “metatheory” of storage capacity limits (...) meant to be useful in future research to settle the issue. I suggest that principles of memory representation determine what parts of the representation will be most prominent but that limits of attention (or of a memory store that includes only items that have been most recently attended) determine the 3- to 5-chunk capacity limit.

Some scholars believe thot Cognitive Science is the attempt to achieve in artificial systems what has already been achieved in the brain. Others, by contrast, argue that the study of ideal adaptive mechanisms could go on without reference to the brain. The author points out that the brain may not be the ideal cognitive device because of biological limitotions on its capacity. Although it may not be ideal, it is still of major interest to cognitive scientists because of the great (...) interest in the human mind, and, in addition, because at this moment the brain is the most important single reservoir of odoptive mechanisms.The paper discusses several areas of neuroscience which are likely to shed light on mechanisms of adaptation. The study of simple nervous systems is likely to reveal important design principles of cognitive devices. The study of complex nervous systems will, of course, exert a major influence. The study of such systems leads to certain general principles concerning the neural circuits involved in complex odoptive behaviors: (1) There exist innate specialized systems for the learning of many specific behaviors that at first might appeor to be purely cultural. (2) There is no evidence for the existence of any all‐purpose computer in the brain. (3) There are many surprising dissociations manifested by the specialized systems in the brain, e.g., a special system for recognition of faces as against other visual patterns. (4) The study of the nervous system enables one to formulate more precise mechanisms for the role of emotion in cognitive function.(5) Some human behoviors con probably be understood poorly or not at all if the neural substrate is not considered. (6) The cognitive systems designed for dealing with ottentionol processes may be among the most complex neural structures which underlie behavior.There are certain other properties of brains that should be kept in mind by the cognitive scientists who are studying human behovior: (1) Brains differ from each other in structure, and it is very likely that the strategy for the solution of certain problems differs from person to person. (2) The presence of certain innate cognitive strategies in the brain may prevent that organism from employing other strategies which might be optimal for other problems. (3) Any theory about a particular cognitive strategy will have implications as to the particular mode of breakdown that might be expected after brain lesions. The study of disordered function from brain disease may thus be a valuable way to test certain cognitive theories. (shrink)

Future work is needed to establish that pure short-term memory is a coherent individual difference attribute that is separable from traditional compound short-term memory measures.

The target article proposes an error theory for religious belief. In contrast, moral beliefs are typically not counterintuitive, and some moral cognition and motivation is functional.

European Portuguese (EP) is a language with variable stress, and the main cues for stress are duration and vowel reduction. Previous behavioral study has reported a stress “deafness” effect in EP when vowel quality cues are unavailable. The present study recorded both event-related potentials (ERPs) and behavioral data to examine the stress processing by native EP speakers in the absence of the vowel quality cues. Our behavioral result was consistent with previous research, showing that when vowel reduction (...) is absent EP speakers demonstrated a stress “deafness” effect similar to that found in speakers of languages with fixed stress or without any lexical stress marking. In the ERP task, both the trochaic and iambic conditions yielded mismatch negativity (MMN) and late negativity, suggesting that EP speakers are able to discriminate the two stress patterns without vowel reduction at the pre-attentive stage. Moreover, the ERP and behavioral data revealed compatible results regarding the pattern of stress bias in EP. In the EPR task, the MMN and late negativity components were more negative and span over a larger temporal window in the iambic condition than in the trochaic condition, indicating a higher sensitivity for the iambic stress pattern. In the behavioral task, EP speakers responded more accurately and more quickly to the iambic stress. These results match recent developmental findings in the acquisition of stress, but speak against the dominant view in EP phonological literature which assumes penultimate stress to be the regular stress pattern. In addition, both the ERP and the behavioral data showed that EP speakers’ stress processing was influenced by their working memory (WM) capacity. The participants with high WM capacity outperformed the participants with limited WM capacity in the iambic condition. In sum, our results broaden the current knowledge on stress processing by EP speakers at both the pre-attentive and attentive levels. (shrink)

To make genuine progress toward explicating the relation between innate talent and high levels of ability, we need to consider the differences in structure between most everyday abilities and expert performance. Only in expert performance is it possible to show consistently that individuals can acquire skills to circumvent and modify basic characteristics (talent).

Cowan assumes a unitary capacity-limited attentional focus. We argue that two main problems need to be solved before this assumption can complement theoretical knowledge about human cognition. First, it needs to be clarified what exactly the nature of the elements (chunks) within the attentional focus is. Second, an elaborated process model needs to be developed and testable assumptions about the proposed capacity limitation need to be formulated.

Habituation is defined as a decline in responding to a repeated stimulus. After more than eighty years of research, there is an enduring consensus among researchers on the existence of 9-10 behavioral regularities or parameters of habituation. There is no similar agreement, however, on the best approach to explain these facts. In this paper, we demonstrate that the Sometimes Opponent Processes (SOP) model of stimulus processing accurately describes all of these regularities. This model was proposed by Allan Wagner as (...) a quantitative elaboration of Priming Theory, which states that the processing of a stimulus, and therefore its capacity to provoke its response, depends inversely on the degree to which the stimulus is pre-represented in short-term memory. Using computer simulations, we show that all the facts involving within-session effects or short-term habituation might be the result of priming from recent presentations of the stimulus (self-generated priming). The characteristics involving between-sessions effects or long-term habituation would result from the retrieval of the representation of the stimulus from memory by the associated context (associatively-generated priming).

We welcome Tomasello’s new book on the natural history of human morality as an important confirmation of the evolutionary approach, which sees adaptive behaviors and their psychological underpinnings as linked to a species’ socioecology (the package of subsistence, social, mating, and rearing systems). This perspective automatically leads to the conclusion that the basic set of moral preferences is a straightforward human adaptation to the derived cooperative foraging niche of nomadic foragers, which involves a high degree of interdependence. We provide more (...) background information in support of this evolutionary approach, call for work on defining the contents of the innate core of moral preferences it implies, and urge philosophers to pursue its implications more seriously. Tomasello also offers a historical reconstruction, but his scenario is not compatible with recent comparative data showing a surprising overlap with aspects of human morality, nor does it fit the currently best-supported evolutionary scenario of hominin foraging. We offer a better-fitting alternative, but also call for more behavioral work in child development and on nonhuman primates to improve this reconstruction. (shrink)

The empirical data do not unequivocally support a consistent fixed capacity of four chunks. We propose an alternative account whereby capacity is limited by the precision of specifying the temporal and spatial context in which items appear, that similar psychophysical constraints limit number estimation, and that short term memory (STM) is continuous with long term memory (LTM).

Although there are various ways to express actions and behaviors in natural languages, it is found in cognitive informatics that human and system behaviors may be classified into three basic categories: to be , to have , and to do . All mathematical means and forms, in general, are an abstract description of these three categories of system behaviors and their common rules. Taking this view, mathematical logic may be perceived as the abstract means for describing to be, set theory (...) for describing 'to have,' and algebras, particularly the process algebra, for describing to do. This is a fundamental view toward the formal description and modeling of human and system behaviors in general, and software behaviors in particular, because a software system can be perceived as a virtual agent of human beings, and it is created to do something repeatable, to extend human capability, reachability, and/or memory capacity. The author found that both human and software behaviors can be described by a three-dimensional representative model comprising action, time, and space. For software system behaviors, the three dimensions are known as mathematical operations, event/process timing, and memory manipulation. This paper introduces the real-time process algebra (RTPA) that serves as an expressive notation system for describing thoughts and notions of dynamic software behaviors. Experimental case studies on applications of RTPA in describing the equivalent software and human behaviors as a series of actions and cognitive processes are demonstrated with real-world examples.
