A set of three studies replicated and extended Abbey's (1982) research, indicating that men perceive less friendliness, but more sexuality than women when observing women's social interactions. Study 1 was based on 49 previously unacquainted male-female pairs who engaged in brief face-to-face discussions, and 48 males and 61 females who observed one of those discussions. Study 2 was based on videotaped exchanges between a male store manager and a female cashier, and Study 3 between a male professor and a female student; 75 males and 88 females participated in Study 2, while 98 males and 102 females participated in Study 3. In all three studies, the men saw less friendliness, but more sexiness in the woman's behavior than the women. These results support the idea that some of the less severe forms of sexual harassment in business and academic settings may be better understood eventually through research and theory development that considers these sex differences in social perceptions. 相似文献

Infertility is a major life stressor that affects approximately 10% of U.S. married couples. Infertile women and men have reported experiencing depression, helplessness, and marital strain. Given U.S. society's emphasis on women's role as mothers, it has been suggested that women's lives are more disrupted by infertility than those of men. This hypothesis was supported in a survey of 185 infertile couples and 90 presumed fertile couples. Infertile wives, as compared to their husbands, perceived their fertility problem as more stressful, felt more responsible for and in control of their infertility, and engaged in more problem-focused coping. Infertile husbands experienced more home life stress and lower home life performance than did their wives. These differences were not found for presumed fertile couples. Both infertile and presumed fertile wives experienced more depression, more sexual dissatisfaction, and lower self-esteem than did their husbands. Theoretical and counseling implications of these findings are discussed. 相似文献

This is the first study to examine whether high school students experiencing frequent bullying behaviors are at risk for later depression and suicidality. A total of 236 students who reported frequent bullying behavior without depression or suicidality during a suicide screening were interviewed 4 years later to reassess depression, suicidal ideation, attempts, substance problems, and functional impairment and were compared to at‐risk youth identified during the screen, including 96 youth who also experienced bullying behavior. Youth who only reported frequent bullying behaviors (as bullies, victims, or both) did not develop later depression or suicidality and continued to have fewer psychiatric problems than students identified as at‐risk for suicide. Students who experienced bullying behaviors and depression or suicidality were more impaired 4 years later than those who had only reported depression or suicidality. Thus, assessment of bullying behaviors in screening protocols is recommended. 相似文献

To determine the differential effects of maternal emotional and physical unavailability on infant interaction behavior, 4-month-old infants were subjected to the mothers' still-face and to a brief separation from the mother. Although the infants became more negative and agitated during both conditions, the still-face was more stressful. 相似文献
