Nonhuman Animals

Abstract There is a large body of research on conflict in nonhuman animal groups that measures the costs and benefits of intergroup conflict, and we suggest that much of this evidence is missing from De Dreu and Gross's interesting article. It is a shame this work has been missed, because it provides evidence for interesting ideas put forward in the article.

Metabolic Activities

Space Lab 3 (SL-3) was flown on Shuttle Challenger providing an opportunity to measure the effect of spaceflight on rat testes. Cannon developed the idea that organisms react to unfavorable conditions with highly integrated metabolic activities. Selye summarized the manifestations of physiological response to nonspecific stress and he pointed out that atrophy of the gonads always occurred. Many papers have been published showing the effects of social interaction, crowding, peck order and confinement. Flickinger showed delayed testicular development in subordinate roosters influenced by group numbers, social rank and social status. Christian reported increasing population size in mice resulted in adrenal hypertrophy, inhibition of reproductive maturation and loss of reproductive function in adults. Sex organ weights also declined. Two male dogs were flown on Cosmos 110 for 22 days. Fedorova reported an increase of 30 to 70% atypical spermatozoa consisting of tail curling and/or the absence of a tail.

Adolescent Voice

Seventy-eight subjects, identified as possessing voice quality aberrations for six months, constituted four experimental groups: breathiness, harshness, hoarseness, and nasality. A control group included 38 subjects. The four experimental groups were compared with the control group according to personality characteristics and peer evaluations. The results of these comparisons indicated that there was no relationship between voice quality aberration and either personality characteristics or peer evaluations.

The Relationship

Research has shown that perceived group status positively predicts competence stereotypes but does not positively predict warmth stereotypes. The present study identified circumstances in which group status positively predicts both warmth and competence judgments. Students (N = 86) rated one of two groups (psychologists vs. engineers) presented as either being low or high in social status on warmth and competence. Results showed that status positively predicted competence stereotypes for both groups, but warmth stereotypes only for psychologists, for whom warmth traits are perceived to be functional in goal achievement. Moreover, for psychologists perceived warmth mediated the relationship between status and perceived competence. Results are discussed in terms of the contextual malleability of the relationship between perceived status, warmth, and competence.
