This article concerns a family whose son was treated for two years by chemotherapy, the parents participating for part of that time in a parents' group, without any significant changes in behavior. Family therapy was initiated, with the inclusion of family art therapy, which immediately provided highly significant diagnostic data not otherwise observable. It also served as a dramatic catalytic agent for constructive change as evidenced by other family sessions.  相似文献

A total of 160 female and male college students read a completed job application and an article written by the applicant. Both the job and the article were in nonsex-typed fields. The applicant was described as either female or male, and as either married, never married, widowed, or divorced. Subjects answered eight evaluate questions concerning the competence of the applicant and the merits of the article. Neither the sex nor the marital status of the applicant had a strong or consistent effect on the subjects' evaluations.  相似文献

The threshold, latency, and peak fundamental frequency (basic pitch) of crying were sensitive to the subclinical effects of prenatal alcohol exposure through the first month of postnatal life. Whereas infants with prenatal alcohol exposure showed a lower cry pitch and higher cry threshold at 2 days of age, higher pitched cries, typical of nervous system insult, were evident at 14 and 28 days. A longer latency was also evident at 14 days.  相似文献

This study explores various aspects of support in the social network of long-term single mothers: the nature of expected help and of offered support, the attitudes behind support, the strategies for requesting help, the reluctance to ask, the efficacy of received help, the perceived refusals, and the behaviors judged as harmful. Thirty women separated for at least two years with a child aged under 10 were chosen following the snowball technique, and participated in this study. The content analysis of the semi-structured interviews shows how the dynamics of social support varies according to the relationship to the target person: ex-partner, family, friends, or “other relationships”. For instance the ex-partner, when mentioned, rarely offered the expected support and was perceived as harmful. Family members often lived up to their expectations, but women were generally very reluctant to ask them for help. Friends were the most efficient helpers and were the main persons from whom mothers expected cognitive support. The “other relationships” offered a certain amount of help, especially at the instrumental level but, as with the ex-partner, they were frequently perceived as harmful. Finally, we advocate for an “ecological” approach to measure social support in the context of the interaction in which it occurs.  相似文献

The purpose of this study was to examine whether level of job performance interacts with marital and parental status to influence evaluations of employed women. College students (104 females and 104 males) evaluated a stimulus person on 24 scales describing personality traits and job performance characteristics. Each participant rated 1 of 8 employed women depicted as either an outstanding or below-average worker, divorced or married, with one or no children. Compared to below-average workers, outstanding workers were rated as better-adjusted (especially if they were mothers) and more professionally and socially competent (especially if they were not mothers). Married women were perceived as better-adjusted than divorced women. Mothers were viewed as more nurturant than nonmothers.Portions of this paper were presented at the meeting of the American Psychological Association, New Orleans, Lousiana, August 1989.  相似文献

We believe that members of the scientific community have a primary obligation to promote integrity in research and that this obligation includes a duty to report observations that suggest misconduct to agencies that are empowered to examine and evaluate such evidence. Consonant with this responsibility, we became whistleblowers in the case of Herbert Needleman. His 1979 study (Needleman et al., 1979), on the effects of low-level lead exposure on children, is widely cited and highly influential in the formulation of public policy on lead. The opportunity we had to examine subject selection and data analyses from this study was prematurely halted by efforts to prevent disclosure of our observations. Nevertheless, what we saw left us with serious concerns. We hope that the events here summarized will contribute to revisions of process by which allegations of scientific misconduct are handled and that such revisions will result in less damage to scientists who speak out.  相似文献
