Personal involvement and the evaluation of group products

This research examined favouritism in group product evaluations as a function of personal involvement. After being divided into groups on an arbitrary basis, subjects worked at a group brainstorming task. Some subjects then assessed the merits of their own group's product relative to that of an outgroup's product, whereas other subjects assessed the merits of an ingroup's product relative to that of an outgroup's product. In both conditions, a significant bias was observed such that owngroup and ingroup products were rated as superior to outgroup products. Moreover, this bias was equally strong regardless of whether subjects were appraising a product they had personally helped create. The implications of the findings for understanding the antecedents of group bias are considered.     

Keeping the therapist alive

This article focuses on ways in which therapists can mamtain vitality in their work with people. Becoming more aware of personal dynamics, particularly of the need for control and power, is essential. To remain open to new theories and approaches avoids the pitfall of professional encapsulation. Experiencing the client as a person not only facilitates empathy but involves therapists in the growth process as well. Developing a tragic awareness of life enables therapists to maintain a sense of awe, wonder, and grace toward the human predicament, thus bringing depth or spirituality to their work.He is also editor of TheHarding Journal of Religion and Psychiatry.     

Exploring environments by hand or foot: time-based heuristics for encoding distance in movement space

In Experiment 1, blindfolded observers judged (a) the distance of pathways felt by hand and (b) the straight-line distance between pathway endpoints inferred from such exploration. In Experiment 2, blindfolded observers made corresponding estimates after traversing similar pathways on foot. Pathways were explored under three different speeds. Under both manipulatory and ambulatory exploration, there was substantial length distortion of inferred distance: The straight-line distance was increasingly overestimated with increases in the length of the explored pathway. With manipulatory exploration, slower movements increased length distortion, but duration effects proved secondary to effects of spatial extent. For ambulatory exploration, no duration effects were obtained. Observers used time-independent heuristics, that is, a footstep metric for estimating the pathway actually travelled and a spatial imaging strategy for estimating the inferred line between pathway endpoints. The studies establish length distortion as a general phenomenon in movement space and identify its major causes as spatial rather than temporal.     

Double-blind and triple-blind assessments of medication and placebo responses in hyperactive children

Hyperactive boys taking psychostimulant medication were studied using a randomized, placebo-controlled, crossover design. Behavior ratings and medication guesstimates were obtained for the boys when they were given methylphenidate (Ritalin) and when they were given a placebo. The ratings showed positive medication-related changes, and the guesses, done by independent judges, were significantly better than chance. The pattern of ratings for double-blind and triple-blind raters was identical. These results imply that positive psychostimulant effects are not attributable to rater sensitization or expectancy. The medication-placebo differences were highly reliable for the group comparisons and were in the predicted direction for 21 of 22 individuals, but the magnitude of the change for many individuals was not dramatic. Implications for child psychopharmacology research and differences between clinical and experimental significance are discussed.This research program was supported by NIMH grant MH 29475. Medications and matching placebos were supplied by CIBA. The authors appreciate the assistance of Howard Adelman and the staff of Fernald School, where the program was housed.

Assessing self-report of pain: A comparison of two recording procedures

Intensive vs. reduced demand self-monitored pain levels were compared in nine pain patients. Each patient self-monitored pain intensity on a 6-point scale every 2 hr. Overall, daily mean and maximum pain levels were calculated for each patient (1) across all intervals (intensive self-monitoring) and (2) four times per day, at meal times and bedtime (reduced-demand self-monitoring). Differences were found to be negligible. The reduced-demand procedure produced data that were closely representative of pain fluctuations indicated in the more intensive bihourly ratings. Results are discussed in terms of the representativeness and standardization in pain self-monitoring as well as possible enhancement of recording compliance through the use of the less demanding four times per day procedure.Portions of these data were presented at the meeting of the Association for Behavior Analysis, Dearborn, June 1979.     

Social cognitive processes mediating the relationship between exposure to television's sexual content and adolescents' sexual behavior

This study used multiple-group structural equation modeling to test a model explaining the association between exposure to televised sexual content and initiation of intercourse among an ethnically diverse national sample of 1,292 adolescents. The authors hypothesized, on the basis of social-cognitive theory, that exposure to televised sexual content would influence adolescents' safe-sex self-efficacy, sex-related outcome expectancies, and perceived peer norms regarding sex, and that each of these would, in turn, influence intercourse initiation. Findings support a model in which the relationship between exposure to TV's sexual content and intercourse initiation is mediated by safe-sex self-efficacy among African Americans and Whites but not among Hispanics. Outcome expectancies and perceived peer norms may also mediate the link between exposure and intercourse initiation among all 3 racial/ethnic groups, although evidence of this could not be confirmed.     

Subordinate male mice show long-lasting differences in spatial learning that persist when housed alone

In the wild, house mice live in social groups, whereas in the laboratory male mice are often singly housed. Environmental enrichment such as that provided by social housing has been argued to improve the cognitive performance of laboratory animals in experimental tests. The aim of the present study was to test the cost of aggressive social interactions on learning in male CD-1 mice. We found that subordinate mice from more aggressive dyads showed spatial learning impairment, measured as alternation on a T-maze. Learning impairments in subordinates have hitherto been presumed attributable to the animals' exposure to, and relative standing within, the social group. By contrast, the impairment we observed could not have been the result of recent social defeat because it persisted weeks later when the mice were housed alone. Elevated urinary corticosterone predicted later subordination, though paradoxically these abnormally high levels were reduced by pair housing.
