Family and contextual predictors of depression in inner-city, African American youth have rarely been examined. In this study we explore the contribution of current and historical life events, family conflict, perceived social support from mother, maternal depression, and maternal explanatory style to the depressive symptoms of inner-city African American school-age (M = 10.7 years) children. Home interviews were conducted with 89 mother and child dyads living in moderate- to high-violent areas of a southeastern city. Regression analyses revealed that the children in this sample with higher levels of depressive symptoms had higher levels of child-reported everyday stress, were more likely to have been abused at some point in their past, came from homes with mothers who were less well educated, and had mothers who reported higher levels of depression, a past history of domestic abuse, as well as a less pessimistic explanatory style. Implications for interventions with inner-city African American families are discussed.  相似文献

The current study prospectively examined the impact of social support on symptom severity and recovery from episodes in bipolar disorder, both as a direct influence and as a buffer of life events. Fifty-nine individuals with Bipolar I disorder were followed longitudinally with monthly symptom severity interviews. Social support was measured by the Interpersonal Support Evaluation List and the Interview Schedule for Social Interaction, and life events were assessed using the Life Events and Difficulties Schedule. Individuals with low social support took longer to recover from episodes and were more symptomatic across a 6-month follow-up. Results suggest a polarity-specific effect, in that social support influences depression but not mania. Discussion focuses on theoretical implications of a series of polarity-specific findings within the field.  相似文献

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

Three eye movement experiments were conducted to examine the role of letter identity and letter position during reading. Before fixating on a target word within each sentence, readers were provided with a parafoveal preview that differed in the amount of useful letter identity and letter position information it provided. In Experiments 1 and 2, previews fell into 1 of 5 conditions: (a) identical to the target word, (b) a transposition of 2 internal letters, (c) a substitution of 2 internal letters, (d) a transposition of the 2 final letters, or (e) a substitution of the 2 final letters. In Experiment 3, the authors used a further set of conditions to explore the importance of external letter positions. The findings extend previous work and demonstrate that transposed-letter effects exist in silent reading. These experiments also indicate that letter identity information can be extracted from the parafovea outside of absolute letter position from the first 5 letters of the word to the right of fixation. Finally, the results support the notion that exterior letters play important roles in visual word recognition.  相似文献

After reviewing portions of the 21st Century Nanotechnology Research and Development Act that call for examination of societal and ethical issues, this essay seeks to understand how nanoethics can play a role in nanotechnology development. What can and should nanoethics aim to achieve? The focus of the essay is on the challenges of examining ethical issues with regard to a technology that is still emerging, still ‘in the making.’ The literature of science and technology studies (STS) is used to understand the nanotechnology endeavor in a way that makes room for influence by nanoethics. The analysis emphasizes: the contingency of technology and the many actors involved in its development; a conception of technology as sociotechnical systems; and, the values infused (in a variety of ways) in technology. Nanoethicists can be among the many actors who shape the meaning and materiality of an emerging technology. Nevertheless, there are dangers that nanoethicists should try to avoid. The possibility of being co-opted from working along side nanotechnology engineers and scientists is one danger that is inseparable from trying to influence. Related but somewhat different is the danger of not asking about the worthiness of the nanotechnology enterprise as a social investment in the future.  相似文献
