Similarity,Sex, and Requests for Small Favors1

To determine whether correspondence in appearance between helper and helped will increase the rate of helping behavior, two types (Hippie and Straight) and two sexes of experimenters approached each of the four corresponding types of subjects and asked to borrow a dime for a telephone call. As predicted, a significantly greater number of persons were willing to lend money to someone who resembled them in appearance. Furthermore, as predicted, his tendency to match on the basis of appearance was stronger for male subjects than for female subjects. It was hypothesized that dress styles, like race, provide a basis for assumptions about other areas of similarity and create a greater willingness to help a similar other.     

海马CA_3区在长时记忆的保持中的作用

本工作将M-胆碱能受体阻断剂东莨菪碱,r-氨基丁酸及其受体阻断剂印防己毒素,经埋植的慢性导管注入家兔双侧海马CA_3区,观察上述药物对已巩固的操作式食物性条件反应的影响。发现东莨菪碱(每侧45微克/5微升)、r-氨基丁酸(每侧3毫克/5微升)均使条件反应抑制;若注r-氨基丁酸之前先加注印防己毒素,则抑制时间缩短,且剂量愈大时间更为缩短。抑制期间动物的摄食和运动功能正常,抑制后条件反应皆恢复;注生理盐水作自身对照则均无抑制效应。这表明海马CA_3区在长时记忆的保持上起着重要作用,且此种作用有胆碱能突触和GABA能突触参与。     

Self-Defeating Behavior Workshops: Systems Approach for Hard-to-Serve Veterans

For the past two and one-half years, the self-defeating behavior (SDB) theory has been applied to a population of veterans who had a history of problems in job training, vocational placement, and academic settings. A group-therapy structure meeting eight times during a four-week period is the basic approach of the SDB seminar. In conjunction with the SDB seminar, a variety of support people and agencies have combined efforts to develop a systems approach to helping the veterans eliminate behaviors that are self-defeating. Results from the systems approach have been excellent.     

Evaluating a sex-related ability: Comparison with same-, opposite-, and combined-sex norms

A study was conducted to replicate and extend Zanna, Goethals, and Hill's (Zanna, M. P., Goethals, G. R., & Hill, J. F. Journal of Experimental Social Psychology, 1975, 11, 86–93) experiment investigating social comparison choices for evaluating a sex-related ability. In a 2 × 3 design male and female undergraduates received ambiguous feedback about their performance on a test. The test was described as one in which either males typically excel or females typically excel, or no sex differences for performance were mentioned. Subjects were then given the opportunity to select normative comparison information in order to evaluate their performance. Information about same-sex, opposite-sex, and combined (male and female) norms was available. The results showed that interest in same-sex and combined information was high on both first and second choices. Opposite-sex comparisons were of low priority. Same-sex comparisons were of high priority even when sex differences were not made salient. Males and females differed to some extent in their comparison choices. The results suggest that while persons prefer to compare with similar (same-sex) others, they are also interested in making broader kinds of comparisons (with combined-sex norms). The results are discussed in terms of Wilson's (Wilson, S. R. Sociometry, 1973, 36, 600–607) two-process analysis of ability comparison and Goethals and Darley's (Goethals, G., & Darley, J. In J. M. Suls & R. L. Miller (Eds.), Social comparison processes; Theoretical and empirical perspectives. Washington, D. C.: Hemisphere/Halsted/Wiley, 1977) related attribute hypothesis.     

Effect of socioeconomic status on general and at-risk high school boys' willingness to accept same-sex peers with LD

Thirty-eight educationally successful and 33 educationally at-risk high school boys from varying SES backgrounds participated in a study to determine their willingness to allow same-sex peers with LD to participate in activities in the school, out-of-school, and both contexts. Kruskal Wallis One-way Analysis of Valance of Ranks results indicated that, regardless of academic designation, boys from low SES backgrounds were more willing than their counterparts to accept peers with LD. Significant differences among SES groups were found in several activities performed in the out-of-school contexts, especially those with emotional or cognitive connotations. Discussion addresses the importance of training classroom teachers and general education students in maintaining an inclusive environment.     

The daily life of the garden-variety neurotic: reactivity, stressor exposure, mood spillover, and maladaptive coping

This article describes a series of studies using the daily process paradigm to describe and understand the affective dynamics of people who experience frequent and intense bouts of a wide range of negative emotions. In several studies, community residents reported on problem occurrence and affect several times a day or at the end of the day. We found reliable evidence that persons who scored high (vs. low) in Neuroticism reported more daily problems, tended to react with more severe emotions, experienced more mood spillover from prior occasions, and exhibited stronger reactions to recurring problems (the "neurotic cascade"). The susceptibility of neurotics to stress seems to extend to all types of problems while certain other dimensions of personality (e.g., Agreeableness) are associated with hyperreactivity to particular kinds of problems. The research demonstrates how daily process research can provide insight about classic problems in the field of individual differences.     

Accountability and need for cognition effects on contrast, halo, and accuracy in performance ratings

In the present study, the authors investigated the effects of accountability and need for cognition on contrast errors, halo, and accuracy of performance ratings examined in good and poor performance context conditions, as well as in a context-free control condition. The accountability manipulation reduced the contrast effect and also modified rater recall of good ratee behavior. Accountability reduced halo in ratings and increased rating accuracy in a poor performance context. Accountability also interacted with need for cognition in predicting individual rater halo.     

When logic fails: Implicit transitive inference in humans

Transitive inference (TI) in animals (e.g., choosing A over C on the basis of knowing that A is better than B and B is better than C) has been interpreted by some as reflecting a declarative logical inference process. We invert this anthropomorphic interpretation by providing evidence that humans can exhibit TI-like behavior on the basis of simpler associative mechanisms that underlie many theories of animal learning. In this study, human participants were trained on a five-pair TI problem (A+B-, B+C-, C+D-, D+E-, E+F-) and, unlike in previous human TI studies, were prevented from becoming explicitly aware of the logical hierarchy, so they could not employ logical reasoning. They were then tested with three problems: B versus D, B versus E, and C versus E. Participants only reliably chose B over E, whereas the other test conditions yielded chance performance. This result is inconsistent with the use of logical reasoning and is instead consistent with an account developed to explain earlier TI studies with rats that found the same pattern of results. In this account, choice performance is based on differential associative strengths across the stimulus items that develop over training, despite equal overt reinforcement.
