Animal studies have demonstrated the interactive effects of prenatal stress exposure and postnatal rearing style on offspring capacity to manage stress. However, little is known about how parenting quality impacts the association between maternal prenatal anxiety and stress reactivity in human infants. This prospective study examined the impact of prenatal anxiety disorder and maternal caregiving sensitivity on infants’ responses to a standardised interactive stressor (still-face procedure). Eighty-four women completed a clinical interview during pregnancy to assess anxiety symptoms meeting DSM-IV diagnostic criteria. At infant age 7 months, maternal sensitivity to infant distress and infant negative affect were observed and coded during the still-face procedure. Maternal postnatal (concurrent) anxiety and depression were also assessed at this time. Results indicated a negative association between maternal sensitivity to infant distress and infant negative affect responses to the still-face procedure. An unexpected finding was a positive association between parity and infant reactivity. The main effect for sensitivity was qualified by a significant interaction, p < .05, suggesting that the impact of sensitivity was particularly marked among infants of women who experienced an anxiety disorder during pregnancy. This finding is consistent with a cumulative risk model suggesting that maternal prenatal anxiety and quality of maternal care act in concert to shape infant outcomes. 相似文献

Although evidence suggests that negative task and self-evaluations are associated with emotional exhaustion, little research has examined factors that buffer against these effects. We propose that perceived prosocial impact, the experience of helping others, compensates for negative task and self-evaluations by focusing attention on positive outcomes for others. In Study 1, perceived prosocial impact attenuated the associations of low intrinsic motivation and core self-evaluations with emotional exhaustion among professional fundraisers. Study 2 replicated these results among public sanitation employees and extended them to supervisor performance ratings. Mediated moderation analyses indicated that by protecting against emotional exhaustion, perceived prosocial impact compensated for low intrinsic motivation and core self-evaluations to predict higher performance ratings. Our studies extend theory and research on burnout, helping, and citizenship. 相似文献

The purpose of this study was to examine the impact of ethnicity on perceptions of voluntary childfree women. We were interested in determining whether mothers were viewed as more stereotypically positive than women without children and how the ethnicity of the participant and the target impacted participants' ratings. We utilized vignettes and manipulated motherhood status and ethnicity of the target. Participants (n = 224) were comprised of female university students in the southwestern region of the United States. Results indicated that women view childfree women negatively. Moreover, women view African American mothers more favourably than childfree African American women. Results are discussed in terms of gender roles in communities of colour.

To test whether activity-based anorexia (ABA) still occurs after preadaptation to the feeding schedule, 20 rats were first exposed to a feeding schedule of one 90-min meal per day until adaptation occurred (measured by maintenance of stable body weight). Then, during ABA training, half the rats (wheel group) were confined in running wheels except during the daily meal, and half (cage group) were not. Wheel running suppressed feeding—that is, food intake in the wheel group was less than that in the cage group. Also, the rats in the wheel group lost weight, whereas those in the cage group did not. Wheel running increased over days. Thus, the defining characteristics of ABA were evident in rats that were not subjected to ABA training until after they had become well adapted to the feeding schedule. These findings support the view that the suppression of feeding produced by wheel running triggers the vicious circle of ABA. They also cast doubt on the hypothesis that activity-induced interference with adaptation to the feeding schedule plays a key role in causing ABA. 相似文献
