Vivid: How valence and arousal influence word processing under different task demands

In this study, we used event-related potentials to examine how different dimensions of emotion—valence and arousal—influence different stages of word processing under different task demands. In two experiments, two groups of participants viewed the same single emotional and neutral words while carrying out different tasks. In both experiments, valence (pleasant, unpleasant, and neutral) was fully crossed with arousal (high and low). We found that the task made a substantial contribution to how valence and arousal modulated the late positive complex (LPC), which is thought to reflect sustained evaluative processing (particularly of emotional stimuli). When participants performed a semantic categorization task in which emotion was not directly relevant to task performance, the LPC showed a larger amplitude for high-arousal than for low-arousal words, but no effect of valence. In contrast, when participants performed an overt valence categorization task, the LPC showed a large effect of valence (with unpleasant words eliciting the largest positivity), but no effect of arousal. These data show not only that valence and arousal act independently to influence word processing, but that their relative contributions to prolonged evaluative neural processes are strongly influenced by the situational demands (and by individual differences, as revealed in a subsequent analysis of subjective judgments).     

The Relationship Between Mindfulness and Multicultural Counseling Competence

The authors examined the association between multicultural counseling competence (MCC) and mindfulness. Previous authors have maintained a conceptual link between MCC and mindfulness; however, this is the first empirical analysis of the relationship between MCC and mindfulness. Results revealed that, after race/ethnicity, multicultural course completion, and empathy were controlled, components of mindfulness were correlated with multicultural awareness and multicultural knowledge. These results have implications for counselor education, counseling practice, and future research.     

Nothing but the Evidential Considerations?

A number of philosophers have claimed that non-evidential considerations cannot play a role in doxastic deliberation as motivating reasons to believe a proposition. This claim, interesting in its own right, naturally lends itself to use in a range of arguments for a wide array of substantive philosophical theses. I argue, by way of a counterexample, that the claim to which all these arguments appeal is false. I then consider, and reply to, seven objections to my counterexample. Finally, as a way of softening the blow, I show how the counterexample itself suggests a plausible diagnosis of why this claim has seemed so plausible to so many.     

Herman Bavinck on the Image of God and Original Sin

The organic motif is Bavinck's preferred means to communicate creation's triune shape. An archetypal unity‐in‐diversity in the Godhead implies that creation displays an ectypal unity‐in‐diversity. This article argues that Bavinck's organic ontology provides him with a theological rationale for a doctrine of original sin in which the covenant headship of Adam reflects the organic character of humanity in unity and diversity. Thus, the transmission of original guilt on account of Adam's trespass is not a mere special ordinance by an inscrutable divine will, but an expression of humanity's organic shape. The article concludes by drawing some implications of Bavinck's construction for current discussion concerning original sin.     

Cognitive style and religiosity: The role of conflict detection

Recent research has indicated a negative relation between the propensity for analytic reasoning and religious beliefs and practices. Here, we propose conflict detection as a mechanism underlying this relation, on the basis of the hypothesis that more-analytic people are less religious, in part, because they are more sensitive to conflicts between immaterial religious beliefs and beliefs about the material world. To examine cognitive conflict sensitivity, we presented problems containing stereotypes that conflicted with base-rate probabilities in a task with no religious content. In three studies, we found evidence that religiosity is negatively related to conflict detection during reasoning. Independent measures of analytic cognitive style also positively predicted conflict detection. The present findings provide evidence for a mechanism potentially contributing to the negative association between analytic thinking and religiosity, and more generally, they illustrate the insights to be gained from integrating individual-difference factors and contextual factors to investigate analytic reasoning.     

Achievement Motivation,Expected Coworker Performance,and Collective Task Motivation: Working Hard or Hardly Working?1

Social loafing is the tendency of individuals to work less hard collectively than individually. The present study examined the joint influence of achievement motivation and expected coworker effort on collective task performance. Participants (N= 107) who qualified and were available after pretesting on an achievement motivation scale were randomly assigned to a work condition and coworker effort condition. Dyads were asked to generate as many uses for a knife as possible within a 12‐min time period. Participants low in achievement motivation engaged in social loafing, but only when expected coworker effort was high, whereas participants high in achievement motivation did not engage in social loafing, regardless of expected coworker effort. The implication of achievement motivation for collective task performance settings is discussed.     

Extinction of drug cue reactivity in methamphetamine-dependent individuals

Conditioned responses to drug-related environmental cues (such as craving) play a critical role in relapse to drug use. Animal models demonstrate that repeated exposure to drug-associated cues in the absence of drug administration leads to the extinction of conditioned responses, but the few existing clinical trials focused on extinction of conditioned responses to drug-related cues in drug-dependent individuals show equivocal results. The current study examined drug-related cue reactivity and response extinction in a laboratory setting in methamphetamine-dependent individuals. Methamphetamine cue-elicited craving was extinguished during two sessions of repeated (3) within-session exposures to multi-modal (picture, video, and in-vivo) cues, with no evidence of spontaneous recovery between sessions. A trend was noted for a greater attenuation of response in participants with longer (4-7 day) inter-session intervals. These results indicate that extinction of drug cue conditioned responding occurs in methamphetamine-dependent individuals, offering promise for the development of extinction- based treatment strategies.     

Alexithymia, verbal intellectual deficit, and neurological dysfunction in relation to risk-taking behavior

This study explored relationships between alexithymia (measured through the Toronto Alexithymia Scale), probable neurological dysfunction (Stroop Color Word Test), and “Verbal” and “Abstraction” IQ scores (Hartford-Shipley Institute for Living Scale) in relation to risk-taking behavior. Subjects were “anti-social” risk-takers (criminal offenders undergoing court-related residential drug treatment), “adventurous” risktakers (college students who regularly engage in such sports as rock-climbing and spelunking), or “normals” (college students who were neither adventurous risk-takers nor criminal offenders). Principal findings reveal that clinically relevant alexithymia is observed among risk-takers of either anti-social or adventurous variety less frequently, but among “normals” more frequently, than chance would predict; that the “verbal deficit pattern” in intellectual functioning is observed more frequently among adventurous risk-takers, less frequently among “normals,” and no more frequently among anti-social risk-takers than chance would predict; and that probable neurological dysfunction is observed more frequently among anti-social risk-takers but less frequently among adventurous risk-takers or “normals” than chance would predict. Results support only in part the Pallone-Hennessy (1999) conceptual model of the genesis and correlates of risk-taking in respect of anti-social, but not in respect of adventurous risk-takers. This study was supported by grants from the Henry Rutgers Scholars Program, Rutgers College, and the Fund for Correctional Psychology, Center of Alcohol Studies.
