Team reasoning and collective rationality: piercing the veil of obviousness

The experiments reported in our target article provide strong evidence of collective utility maximization, and the findings suggest that team reasoning should now be included among the social value orientations used in cognitive and social psychology. Evidential decision theory offers a possible alternative explanation for our results but fails to predict intuitively compelling strategy choices in simple games with asymmetric team-reasoning outcomes. Although many of our experimental participants evidently used team reasoning, some appear to have ignored the other players' expected strategy choices and used lower-level, nonstrategic forms of reasoning. Standard payoff transformations cannot explain the experimental findings, nor team reasoning in general, without an unrealistic assumption that players invariably reason nonstrategically.     

Insight without cortex: lessons from the avian brain

Insight is a cognitive feature that is usually regarded as being generated by the neocortex and being present only in humans and possibly some closely related primates. In this essay we show that especially corvids display behavioral skills within the domains of object permanence, episodic memory, theory of mind, and tool use/causal reasoning that are insightful. These similarities between humans and corvids at the behavioral level are probably the result of a convergent evolution. Similarly, the telencephalic structures involved in higher cognitive functions in both species show a high degree of similarity, although the forebrain of birds has no cortex-like lamination. The neural substrate for insight-related cognitive functions in mammals and birds is thus not necessarily based on a laminated cortical structure but can be generated by differently organized forebrains. Hence, neither is insight restricted to mammals, as predicted from a “scala naturae”, nor is the laminated cortex a prerequisite for the highest cognitive functions.     

Who gets a mentor? A longitudinal assessment of the rising star hypothesis

This study assessed the rising star hypothesis, which proposes that individuals who are on the fast track to career success are more likely to gain mentors than others. The study used a sample of employees who had never been mentored and examined the relationship between rising star attributes measured at Time 1 and the attainment of a mentor a year later. In support of the hypothesis, individuals who were on the fast-track for promotion, had higher advancement expectations, and engaged in more proactive career behaviors were more likely to gain a mentor than individuals lacking these attributes. Implications of these results for the theory, research and practice of mentoring are discussed.     

Assessment of the Relatedness of Equivalent Stimuli Through a Semantic Differential

The Psychological Record - If stimulus equivalence is a model of meaning, abstract stimuli should acquire the meaning of meaningful stimuli equivalent to them. In Experiment 1, college students...     

Age differences in what is viewed and remembered in complex conjunction search

Older and younger adults searched arrays of 12 unique real-world photographs for a specified object (e.g., a yellow drill) among distractors (e.g., yellow telephone, red drill, and green door). Eye-tracking data from 24 of 48 participants in each age group showed generally similar search patterns for the younger and older adults but there were some interesting differences. Older adults processed all the items in the arrays more slowly than the younger adults (e.g., they had longer fixation durations, gaze durations, and total times), but this difference was exaggerated for target items. We also found that older and younger adults differed in the sequence in which objects were searched, with younger adults fixating the target objects earlier in the trial than older adults. Despite the relatively longer fixation times on the targets (in comparison to the distractors) for older adults, a surprise visual recognition test revealed a sizeable age deficit for target memory but, importantly, no age differences for distractor memory.     

Cognitive behavioral therapy for panic disorder and comorbidity: more of the same or less of more?

This study compared the effects of a higher dose of cognitive behavioral therapy (CBT) for panic disorder versus CBT for panic disorder combined with "straying" to CBT for comorbid disorders in individuals with a principal diagnosis of panic disorder with or without agoraphobia. Sixty-five participants were randomly assigned to one of two treatment conditions, either CBT focused solely upon panic disorder and agoraphobia or CBT that simultaneously addressed panic disorder and agoraphobia and, to a lesser degree, the most severe comorbid condition. Results indicated a significant reduction in panic disorder severity and a decline in severity of comorbid diagnoses across both treatment conditions. However, individuals receiving CBT focused only on panic disorder were more likely to meet high end-state functioning at post-treatment, even in intent-to-treat analyses, and report zero panic attacks at the 1-year follow-up, although this effect was not retained in intent-to-treat analyses. At follow-up, CBT focused only on panic disorder yielded more substantial improvement in the most severe baseline comorbid condition, although not in intent-to-treat analyses, and a greater proportion of individuals in this treatment condition were rated as having no comorbid diagnoses, even in intent-to-treat analyses. These findings raise the possibility that remaining focused on CBT for panic disorder may be more beneficial for both principal and comorbid diagnoses than combining CBT for panic disorder with 'straying' to CBT for comorbid disorders.     

What is the function of nail biting: an analog assessment study

OBJECTIVE: To compare the frequency of nail biting in 4 settings (interventions) designed to elicit the functions of nail biting and to compare the results with a self-report questionnaire about the functions of nail biting. DESIGN: Randomised allocation of participants to order of conditions. SETTING: University Psychology Department. SUBJECTS: Forty undergraduates who reported biting their nails. INTERVENTIONS: Left alone (boredom), solving maths problems (frustration), reprimanded for nail biting (contingent attention), continuous conversation (noncontingent attention). MAIN OUTCOME MEASURES: Number of times the undergraduates bit their nails. RESULTS: Nail biting occurred most often in two conditions, boredom and frustration. CONCLUSION: Nail biting in young adults occurs as a result of boredom or working on difficult problems, which may reflect a particular emotional state. It occurs least often when people are engaged in social interaction or when they are reprimanded for the behavior.     

Aging and a benefit of distractibility

Under instructions to ignore distraction, younger and older adults read passages with interspersed distracting words. Some of the distractors served as solutions to a subsequent set of verbal problems in which three weakly related words could be related by retrieving a missing fourth word (i.e., the Remote Associates Test [RAT]; Mednick, 1962). Older adults showed significant priming from the distraction, whereas younger adults did not. In this study, we present a case in which age-related reductions in attentional control over information that was not initially relevant can actually lead to superior performance for older adults.

The discovery of southern childhoods: psychology and the transformation of schooling in the Jim Crow South

Although the psychology of race in America has been the subject of significant research, psychological science in the principal region of racial interaction before Brown v. Board of Education-the South--has received little attention. This article argues that the introduction of psychological ideas about children by means of school reform in the South during the half-century before the Brown decision established a cultural foundation for both Black resistance to segregated schools and White determination to preserve them. In 1900, southern children and their schools were an afterthought in a culture more committed to tradition and racial stability than innovation and individual achievement. The advent of northern philanthropy, however, brought with it a new psychology of childhood. Although the reformers did not intend to subvert segregation, their premises downplayed natural endowment, including racial inheritance, and favored concepts highlighting nurture: that personality is developmental, childhood foundational, and adversity detrimental. Decades of discussion of children in their learning environment gave southern Blacks a rationale for protest and Whites a logical defense for conservative reaction.
