Using cognitive models to map relations between neuropsychological disorders and human decision-making deficits

Findings from a complex decision-making task (the Iowa gambling task) show that individuals with neuropsychological disorders are characterized by decision-making deficits that lead to maladaptive risk-taking behavior. This article describes a cognitive model that distills performance in this task into three different underlying psychological components: the relative impact of rewards and punishments on evaluations of options, the rate that the contingent payoffs are learned, and the consistency between learning and responding. Findings from 10 studies are organized by distilling the observed decision deficits into the three basic components and locating the neuropsychological disorders in this component space. The results reveal a cluster of populations characterized by making risky choices despite high attention to losses, perhaps because of difficulties in creating emotive representations. These findings demonstrate the potential contribution of cognitive models in building bridges between neuroscience and behavior.     

The Rediscovery of the Human Mind: The Discursive Approach

The demise of behaviorism was followed by a period of cognitive model building, on Cartesian lines, invoking unobservable cognitive processes, then "mind behind the mind". This has been followed by a second cognitive revolution which emphasizes the idea that mind is a flow of private and public symbolic patterns, created according to local norms. Basing psychology on this insight requires the preservation of the psychological concepts of ordinary languages as part of the basis for scientific psychology. The concept of 'skill' can be used to link individuals with the matrix of interpersonal symbolic and practical interactions. The second revolution can be illustrated by recent work on emotion displays as discursive acts, and by studies on the role of pronouns in the expression of a sense of personal identity.     

A multisensory interaction effect in the conceptual realm of time

Recent studies on the conceptualization of abstract concepts suggest that the concept of time is represented along a left-right horizontal axis, such that left-to-right readers represent past on the left and future on the right. Although it has been demonstrated with strong consistency that the localization (left or right) of visual stimuli could modulate temporal judgments, results obtained with auditory stimuli are more puzzling, with both failures and successes at finding the effect in the literature. The present study supports an account based on the relative relevance of visual versus auditory-spatial information in the creation of a frame of reference to map time: The auditory location of words interacted with their temporal meaning only when auditory information was made more relevant than visual spatial information by blindfolding participants.     

Influence of clinical status in the relationship between alexithymia and emotional recognition: a dimensional study

The results of this study are part of an investigation to determine whether the cognitive-emotional process of emotional recognition is deficient as a function of the clinical condition and alexithymia in subjects with somatization. This investigation applied the self-assessment of emotion and used a procedure that minimizes the use of verbal skills and verbal comprehension. The specific goal of this study was to verify whether there were differences in the covariation between alexithymia and self-evaluation of the emotional reaction in clinical and nonclinical subjects. The results of this study highlight the significant differences between clinical and control subjects. There were inverse significant correlations with the affective valence in clinical subjects, whereas in the ratings of the TAS-20 in control subjects, there were direct correlations with activation. In the conclusions, we discuss whether the variability of the results of previous research of the relationship between alexithymia and emotional recognition is a characteristic feature of this relationship or an effect of the different sampling and procedures utilized.     

On the robustness and the direction of the effect of cause‐related marketing

Two experiments are presented in this paper that explore the effect of cause‐related marketing (CRM) on product choice. To allow evaluation of the effect of experience and the role of individual differences, the experiments used a repeated choice setting. The results of Experiment 1 showed that the effect of CRM was stable over time. However, the direction of the effect was sensitive to the value of the product. CRM served as an equaliser: it helped disadvantaged alternatives and reduced the attractiveness of superior alternatives. Experiment 2 showed that the effect of CRM decreased but did not disappear in an easy choice task. These findings are summarised in a simple model and discussed in terms of their potential marketing applications. Copyright © 2003 Henry Stewart Publications.     

Support for Self‐Censorship Among Israelis as a Barrier to Resolving the Israeli‐Palestinian Conflict

Self‐censorship, defined as an “act of intentionally and voluntarily withholding information from others in the absence of formal obstacles” often serves as a barrier to resolving intractable conflicts. Specifically, in order to protect the group, and in absence of objective constraints such as institutionalized censorship, individuals practice self‐censorship and support its practice by other society members. This prevents free flow and transparency of information, within a society, regarding the conflict and the adversary. In an attempt to investigate the factors that contribute to the functioning of self‐censorship as a sociopsychological barrier to conflict resolution, a longitudinal study was conducted among a large sample of Jews in Israel. The survey was administered in three waves: a few months before, during, and a few months after Israel's Operation Pillar of Defense in the Gaza Strip. The findings showed that armed confrontation can increase support for self‐censorship. In addition, the findings revealed that personal characteristics (e.g., authoritarianism, ethnocentrism, siege mentality) predicted support for self‐censorship, which, in turn, mediated the effect of personal characteristics on support for negotiations and for providing humanitarian aid. The theoretical as well as the applied implications of the findings are discussed.
