39 Years of Suicide Research: A Personal View

This is a personal account of the beginning of clinical research in suicide in a hostile intellectual climate, of the methodology that has informed most of the subsequent research, and of the very durable findings of that work over 12 replications. The genius of the late Dr. Eli Robins lies at the base, not only of this research methodology, but of the diagnostic system that gives it clinical meaning. All of this is now commonplace, but it was not always so.     

Level of instigation and model similarity as determinants of aggressive behavior

A study was conducted to replicate and extend a finding by Wheeler and Levine [1967] indicating that a dissimilar model was more effective in inducing the contagion of aggression than a similar model. On the basis of recent findings suggesting the circumstances under which dissimilar others are more influential than similar others, the following predictions were derived: When subjects are highly instigated, dissimilar models can influence subjects to be more aggressive than can similar models; when subjects are under a low degree of instigation similar models will influence subjects to be more aggressive. Subjects presented their point of view on a case study in a three-person group discussion setting. Then subjects heard the second person (instigator) attack their position in a highly abusive or slightly abusive manner (High vs Low Instigation). Next subjects heard a third person, whom they had been led to believe was similar or dissimilar to themselves, attack the instigator (Similar vs Dissimilar Model). Finally subjects had an opportunity to express their feelings to the instigator. The results supported the predictions.     

Target-biting behavior of individually and group-housed mice and rats

The effects of housing conditions (individual or grouped) on the biting of an inanimate target by confined male mice and rats were measured. It was observed that, for both mice and rats, individual housing markedly increased the number of target bites per session. These results indicate that the target-biting paradigm is sensitive to those factors responsible for the increase in fighting behavior following individual housing.     

Interpersonal problem solving as a mediator of behavioral adjustment in preschool and kindergarten children

An experimental model tested the mediating function of interpersonal cognitive problem solving skills on behavioral adjustment in preschool and kindergarten children. Relative to controls, nursery-trained youngsters improved in three such skills, kindergarten-trained in two. In both the nursery- and kindergarten-trained groups, increased ability to conceptualize alternative solutions to interpersonal problems significantly related to improved social adjustment. Consequential thinking also emerged as a clear behavioral mediator, especially among kindergarten-aged youngsters. Improvement in behavior could not, however, be attributed to change in causal thinking skills. Having identified two significant behavioral mediators in young children, a beginning has been made to isolate specific thinking skills, which, if enhanced, can contribute to healthy social adjustment and interpersonal competence at an early age.     

BINGE DRINKING AMONG AMERICAN COLLEGE WOMEN

This study examines data from questionnaires to establish the prevalence and correlates of women's binge drinking, defined as four or more drinks per episode, at women's colleges ( n = 508) and at coeducational colleges ( n = 9,624). Results showed that women at women's colleges binged less frequently, had fewer alcohol-related problems, experienced fewer negative effects of others' drinking, and were less likely to drink and drive. The correlates of binge drinking were similar for the two groups of women. The differences appear to be related not to the quantity or amount of socializing but to its quality. The absence of fraternities and coeducational dormitories, the reduced likelihood of a party-centered lifestyle, and self-selection factors at women's colleges all may contribute to a healthier environment for women. Interventions designed to lower the risk of college binge drinking should further explore the peer-group contexts in which problem drinking is reduced.     

Externalism and Memory: Jane Heal

Tye claims that an externalist should say that memory content invoking natural kind concepts floats free of the setting where the memory is laid down and is at later times determined by the context in which the memory is revived. His argument assumes the existence of 'slow switching' of the meaning of natural kind terms when a person is transported from Earth to Twin Earth. But proper understanding of natural kind terms suggests that slow switching (contrary to what is often presupposed) is likely never to be completed. Hence the situation of a person unknowingly transported to Twin Earth is not that his memories switch content but rather than he gets two natural kinds confused.
