The rate of scent marking by male rats and consequent olfactory preferences of female rats

An experiment is reported designed to test the hypothesis that female rats might discriminate between males that differed in the quantity of odor deposited by scent marking. Male odor donors were selected by prior screening for high or low rates of scent marking in an open arena. Females were then tested to determine whether they showed any preference for males that marked at a high rate. It was found that female rats did discriminate, but that they preferred to remain near males selected for low rates of scent marking.     

A reconsideration of testing for competence rather than for intelligence.

David C. McClelland's 1973 article has deeply influenced both professional and public opinion. In it, he presented five major themes: (a) Grades in school did not predict occupational success, (b) intelligence tests and aptitude tests did not predict occupational success or other important life outcomes, (c) tests and academic performance only predicted job performance because of an underlying relationship with social status, (d) such tests were unfair to minorities, and (e) "competencies" would be better able to predict important behaviors than would more traditional tests. Despite the pervasive influence of these assertions, this review of the literature showed only limited support for these claims.     

Homelessness as psychological trauma. Broadening perspectives.

Most mental health literature on homelessness has focused on characteristics that may be risk factors for homelessness. The authors of this article argue that homelessness itself is a risk factor for emotional disorder and use the construct of psychological trauma--focusing on social disaffiliation and learned helplessness--to understand the potential effects of homelessness. Psychological trauma is likely among homeless individuals and families for three reasons. (a) The sudden or gradual loss of one's home can be a stressor of sufficient severity to produce symptoms of psychological trauma. (b) The conditions of shelter life may produce trauma symptoms. (c) Many homeless people--particularly women--become homeless after experiencing physical and sexual abuse and consequent psychological trauma. Research suggests that negative psychological responses to traumatic events can be prevented or mitigated by a supportive and empowering posttrauma environment. The implications of trauma theory for improving the psychosocial conditions of homeless people are discussed.     

The relationship of early adolescent substance use to extracurricular activities, peer influence, and personal attitudes

Two hundred and thirty-seven seventh- and eighth-grade students were assessed for levels of drug/alcohol use, involvement in extracurricular activities, peer influence, and personal attitudes. Cross-tabulations and the chi-square test of independence were used to statistically compare the three groups (non-users, users, and abusers). Several trends emerged from the data.     

Prospective study of postpartum depression: 4 1/2-year follow-up of women and children

The consequences of maternal postpartum depression for mothers and children were investigated in a 4 1/2-year follow-up study, which included 70 of 99 women who had participated in an earlier study of postpartum depression. Information about maternal adjustment and depression during the follow-up period and child adjustment at age 4 1/2 years was obtained. Women who had experienced a postpartum depression were predicted to be at increased risk for subsequent depression and poor adjustment of their child. Postpartum depression was directly related to subsequent depression but not child problems. Later depression was related to child problems at 4 1/2 years. We concluded that postpartum depression may increase risk for later maternal depression and in turn increases risk for child behavior problems. Intervening with women who have experienced a postpartum depression may reduce likelihood of future depressions and child behavior problems.     

Use of the group in resolving the subjective countertransference

Subjective countertransference can sharply limit any group leader's effectiveness. However, a therapist can use the group itself to identify such a bias and to remove it as an influence. A five-step method for doing this is presented. These steps begin with introspection but hinge upon the analyst's turning to the group for the vital information that, in the end, clarifies the analyst's own perceptions and helps him or her free the group from the harmful effects of any bias.
