Maternal mood disorders such as depression and chronic anxiety can negatively affect the lives of not only mothers, but also of partners, offspring, and future generations. Chronic exposure to psychosocial stress is common in postpartum mothers, and one of the strongest predictors of postpartum depression is social conflict. The objective of the current study was to evaluate the effects of chronic social stress (CSS) during lactation on the maternal behavior (which consists of maternal care and aggression toward a novel conspecific) of lactating rats, as well as on the growth of the dams and their offspring. It was hypothesized that chronic daily exposure to a novel male intruder would alter the display of maternal behavior and impair growth in both the dam and offspring during lactation due to the potentially disruptive effects on maternal behavior and/or lactation. The data indicate that CSS during lactation attenuates maternal care and the growth of both dams and pups, and increases self-grooming and maternal aggression toward a novel male intruder. These results support the use of CSS as a relevant model for disorders that impair maternal behavior and attenuate growth of the offspring, such as postpartum depression and anxiety. 相似文献

Using informant reports on working professionals, we explored the role of listening in interpersonal influence and how listening may account for at least some of the relationship between personality and influence. The results extended prior work which has suggested that listening is positively related to influence for informational and relational reasons. As predicted, we found that: (1) listening had a positive effect on influence beyond the impact of verbal expression, (2) listening interacted with verbal expression to predict influence (such that the relationship between listening and influence was stronger among those more expressive), and (3) listening partly mediated the positive relationships between each of the Big Five dimensions of agreeableness and openness and influence. 相似文献

Past research indicates that men are more physically aggressive than women, but very little research has examined mediators of this gender difference. Indeed, the only established finding to date is that one plausible mediator - namely trait anger - shows no reliable gender difference whatsoever. Drawing on sexual selection theory and social-learning theories, we predicted that revenge may mediate this gender difference even though anger does not. Three studies using both personality questionnaires (Studies 1 and 2) and objective laboratory measures of aggression (Study 3) provided support for this contention. The results provide some of the first evidence for a reliable mediator of gender difference in physical aggression. 相似文献

In the present article, we extend the notion of cultural threat posed by immigrants beyond its current conceptualization as symbolic, collective‐level threats to American culture and identity. Instead, we argue that routine encounters with non‐English‐speaking immigrants cause many individuals to feel threatened because of real barriers to interpersonal communication and exchange. We draw upon survey and experimental data to demonstrate that local contact with immigrants who speak little to no English, as well as incidental exposure to the Spanish language, heighten feelings of cultural threat, which increases anti‐immigrant sentiment and policy preferences. 相似文献

According to so-called “credit views of knowledge,” knowledge is an achievement of an epistemic agent, something for which
an agent is creditable or responsible. One influential criticism of the credit view of knowledge holds that the credit view
has difficulty making sense of knowledge acquired from testimony. As Jennifer Lackey has argued, in many ordinary cases of
the acquisition of testimonial knowledge, if anyone deserves credit for the truth of the audience’s belief it is the testimonial
speaker rather than the audience, and so it isn’t clear that testimonial knowers are appropriately creditable for the truth of their
beliefs. I argue that the credit view of knowledge can be saved from Lackey’s objection by focusing on the way in which testimonial
knowledge is the result of an essentially social epistemic ability. While there is indeed a sense in which a testimonial knower
is only partially epistemically responsible for her testimonial belief, this is consistent with the truth of her belief being
creditable to her in another sense. The truth of her belief is most saliently explained by, and hence is fully creditable
to, an essentially social epistemic ability, an ability that is only partially seated in the knowing subject. 相似文献

Emerging research has examined individual differences in affective forecasting; however, we are aware of no published study to date linking psychopathology symptoms to affective forecasting problems. Pitting cognitive theory against depressive realism theory, we examined whether dysphoria was associated with negatively biased affective forecasts or greater accuracy. Participants (n=325) supplied predicted and actual emotional reactions for three days surrounding an emotionally evocative relational event, Valentine's Day. Predictions were made a month prior to the holiday. Consistent with cognitive theory, we found evidence for a dysphoric forecasting bias-the tendency of individuals in dysphoric states to overpredict negative emotional reactions to future events. The dysphoric forecasting bias was robust across ratings of positive and negative affect, forecasts for pleasant and unpleasant scenarios, continuous and categorical operationalisations of dysphoria, and three time points of observation. Similar biases were not observed in analyses examining the independent effects of anxiety and hypomania. Findings provide empirical evidence for the long-assumed influence of depressive symptoms on future expectations. The present investigation has implications for affective forecasting studies examining information-processing constructs, decision making, and broader domains of psychopathology. 相似文献

The roles of the parvocellular (P) and magnocellular (M) retino-geniculo-cortical pathways during shifts of visual attention were investigated by creating M/dorsal-biased (eg low spatial frequency target, no objects present) and P/ventral-biased (ie high spatial frequency target, the perception of 3-D objects) stimulus conditions and measuring location-based inhibition-of-return (IOR). P/ventral-biased conditions produced the greatest IOR. M/dorsal-biased conditions produced the least IOR, in one instance eliminating it altogether. The results indicate a close relationship between IOR magnitude and relative P/ventral and M/dorsal activity with location-based IOR related more to P/ventral than to M/dorsal activity. 相似文献

Social disadvantage is associated with being overweight, a poor diet and physical inactivity. The NHS Health Trainer Service (HTS) is a national initiative designed to promote behaviour change among socially disadvantaged people in England and Wales. This study reports pre-post changes in body mass index (BMI), associated behaviours and cognitions among service users who set dietary or physical activity goals during a 12-month period (2008-2009; N?=?4418). Sixty-nine percent of clients were from the two most deprived population quintiles and 94.7% were overweight or obese. Mean BMI decreased from 34.03 to 32.26, with overweight/obesity prevalence decreasing by 3.7%. There were increases in fruit and vegetable consumption, reductions in fried snack consumption, increases in frequency of moderate or intensive activity and gains in self-efficacy and perceived health and wellbeing. Clients with higher BMI, poorer diet or less activity at baseline achieved greater change. Findings suggest that the NHS HTS has the potential to improve population health and reduce health inequalities through behaviour change. 相似文献
