Effects of Reasons Analysis on the Accuracy of Predicting Basketball Games1

It is argued that analyzing and listing reasons can lead to poorer predictions because reasoners either access information inappropriate to the task or have difficulty integrating the information they do bring to mind. To test this hypothesis, self-described basketball experts predicted the outcomes of actual basketball games in a national tournament. Half of the participants were asked to analyze and list reasons for their predictions before making them, and half were told explicitly not to analyze their reasons. Compared to nonreasoners, reasoners predicted fewer winners of the games and predicted margins of victory that differed more from both the actual margins of victory and the margins of victory predicted by experts. The relationship between expertise and reasons analysis, and the implications of the results for other domains of prediction are discussed.     

Gender Differences in Depression: The Role Played by Paternal Attitudes of Male Superiority and Maternal Modeling of Gender-Related Limitations

A reanalysis of a large multi-generational,predominantly Caucasian sample of adults found a largegender difference in self-reported depression involvinganxiety, appetite and sleep disturbance, and fatigue (anxious somatic depression) butnot in pure depression unaccompanied bymany of these other symptoms, replicating earlierfindings on high school and college samples. Anxioussomatic depression was prevalent among women whosefathers reported attitudes of male superiority and amongwomen whose mothers reported emphasizing the importanceof professional success but feeling that the jobs they held were not respected by others. Anxioussomatic depression, but not pure depression, was foundto be prevalent among women who did not attend collegeand among those who attended college but felt that the jobs they held were not respected byothers.     

Individual differences in the effects of spontaneous mimicry on emotional contagion

Two experiments explored the role of mimicry and self-perception processes in emotional contagion. In Study 1, 46 subjects watched two brief film clips depicting an episode of startled fear. In a separate procedure, subjects adopted facial expressions of emotion, and reported whether the expressions had caused them to feel corresponding emotions. Those who reported feeling the emotions were identified as more responsive to self-produced cues for feeling. Subjects who visibly moved to mimic the behavior of the actor were significantly more likely to be those who were more responsive to self-produced cues. In Study 2, 57 subjects watched three film clips depicting happy people. During clips when they inhibited the movements of their faces, subjects reported less happiness than during clips when they moved naturally and were able to mimic, or when they exaggerated their movements. This effect occurred only among subjects who, in a separate procedure, had been identified as more responsive to self-produced cues.The authors would like to thank Paul Ekman, Jerry Ginzburg, and an anonymous reviewer for very helpful suggestions for ways to improve the paper.     

Depression combined with somatic symptomatology among adolescent females who report concerns regarding maternal achievement

Recent research suggests that many females who mature during periods of great change in women's roles develop, beginning at adolescence, depressive symptomatology combined with such somatic problems as headache, dyspnea, insomnia, disordered eating, and preference for thinness. In this study of possible psychological mechanisms underlying the apparently paradoxical development of such symptomatology during periods of increased opportunity for women, 20% of females attending a suburban high school reported concerns regarding the limited achievements of their mothers and the limitations being female had placed upon their mothers. Compared to other female students, these respondents exhibited a greater correlation between depressive and somatic symptomatology and a higher prevalence of depression combined with somatic symptomatology. Prevalence of combined symptomatology was particularly high among respondents who also reported paternal biases against females and among those who indicated concerns regarding the limitations that being female had placed upon themselves.     

The evolution of asphyxial defense

From the time animals became dependent upon molecular oxygen as an integral part of their energy-producing processes, they have remained in the shadow of acute asphyxial threat—the blocking of respiratory exchange resulting in the intracellular triad of hypoxia, hypercapnia and acidosis. The most commonly occurring precipitant of acute asphyxia has always been the transfer between air and water environments. Over the last one hundred years studies on a wide range of living organisms, from single cells to complex multicellular organisms like mammals, have demonstrated the presence of well-defined metabolic and cardiovascular-respiratory mechanisms for protecting living things against acute asphyxia. Single-celled animals depend upon anaerobiosis and secondarily hypometabolism. In addition to these processes, animals with gills or lungs utilize “passive” protection such as increased oxygen storage and the “dynamic” cardiovascular adjustments of bradycardia and selective ischemia. These latter changes decrease overall oxygen consumption and hence utilize the oxygen stores in the most economical way to protect the cardiac and cerebral tissue, which are most sensitive to hypoxia and vital to continued survival of the organism. In this article an attempt is made to place these processes into an evolutionary context. As through a glass darkly we glimpse asphyxial defense running like a paleophysiological thread through hundreds of millions of years, being accentuated here and muted there, depending upon the particular needs of individual species.     

A taylor-russell/naylor-shine utility calculator

A program for calculating the Taylor-Russell and Naylor-Shine utility estimates is described. These utility estimates are used for determining the benefit to an organization of certain personnel interventions such as training and selection. Calculation of these estimates involves inversion of the standard normal cumulative distribution function and computation of the standard bivariate normal integral.     

Dynamic and Static Work-Family Relationships

This study investigated the linkages between work and family of 281 dual-employed couples. First, we developed a theoretical framework, distinguishing between the causal direction and the sign of the relationship between work and family. We classified the social and psychological mechanisms that explain specific directions and signs of work–family relationships and reviewed the empirical literature from the point of view of this framework. We then provided an illustration of how this framework can be used to generate a model for a specific sample. We generated a model and corresponding hypotheses for a sample of dual-employed couples in which the male′s career was dominant and analyzed these hypotheses by testing males and females separately using LISREL 7. In our sample, the relationship between work and family was reciprocal for males, suggesting a dynamic system in which males were able to adjust one domain to compensate for the other. Females exhibited a unidirectional relationship from family to work involvement, suggesting a static system. For both males and females, the family → work involvement relationship was negative as hypothesized. For males, the work → family relationship was positive. There were some similarities and some differences in the influence of exogenous constructs in the models for males and females. Results are discussed in terms of the importance of understanding dynamic versus static models of work and family relationships and the potential role of organizations in helping their employees lower the fixed demands of the family.     

Children use vowels to help them spell consonants

English spelling is highly inconsistent in terms of simple sound-to-spelling correspondences but is more consistent when context is taken into account. For example, the choice between ch and tch is determined by the preceding vowel (coach, roach vs. catch, hatch). We investigated children's sensitivity to vowel context when spelling consonants in monosyllabic nonwords. Second graders (7-year-olds) tended to use vowel context correctly when spelling word-final consonants (codas). This use of context was progressively stronger for third and fifth graders as well as for college students. The increase is not due to differences in vocabulary because the contextual patterns are similar in reading materials targeted at all four age groups. Vowel letters (graphotactics) had a stronger influence than did vowel pronunciation. Children also used vowel context when spelling word-initial consonants (onsets); this effect was as strong for second graders as for adults. Thus, novice spellers take advantage of graphotactic information.
