Both stress and blunted reward responsiveness have been identified as core risk factors of depression. Whether blunted reward responsiveness increases psychological vulnerability to real-life stress from a dynamic perspective (from stress reactivity to recovery) has not been investigated. By utilizing a real-world stressful event (i.e. the final examination), this study aimed to explore the role of reward responsiveness in the stress-emotional distress relationship during stress reactivity and recovery phases. We followed 57 undergraduates with three assessments, from six weeks before examination weeks (T1, baseline), one day before the examinations (T2) to two weeks after the examinations (T3), therefore, covering stress reactivity (T1 to T2) and recovery (T2 to T3) phases. At baseline, reward responsiveness was measured as the Reward Positivity (RewP) in the doors task. Stress and emotional distress (anxiety and depression) were reported at T1, T2 and T3 to capture their dynamic changes. Results showed that self-report stress levels significantly increased from T1 to T2 (stress reactivity phase) and decreased from T2 to T3 (stress recovery phase). Furthermore, blunted reward responsiveness at baseline prospectively predicted emotional distress during the stress reactivity phase but not the recovery phase. Specifically, during the stress reactivity phase, higher perceived stress was associated with greater anxiety and depression only in participants with relatively smaller residual RewP amplitudes but not in participants with relatively larger residual RewP amplitudes. Our study demonstrated that a blunted reward responsiveness is a vulnerable factor of depression, especially when exposed to stress. Our findings provide insights into prevention and intervention for stress-related disturbance. 相似文献

儿童汉字读音声旁一致性意识的发展 总被引:17,自引:3,他引:14
采用同音判断的方法,考察儿童对汉字读音声旁一致性意识的发展。一个熟悉字和一个不熟悉字共用同一个声旁,该声旁在提示整字发音时可以是一致的,即包含此声旁的所有汉字都发音相同,也可以是不一致的。要求儿童猜测不熟悉字的读音,作出它与熟悉字“是”、“否”同音的判断。结果发现,儿童很早就意识到汉字的结构以及声旁和形旁在表音、表义功能上的分工。随着年级的升高,声旁一致性对猜测不熟悉汉字读音的影响增强。小学四年级语文能力较高的儿童已经开始意识到声旁的一致性;六年级儿童总体上说来已发展了一致性意识。初二年级的学生发展了声旁一致性意识,且没有能力差异。大学生的声旁一致性意识最强。 相似文献

Social exclusion is widespread in our modern society. In the context of marketing, consumers who are excluded will choose specific products to mitigate the negative consequences of exclusion. This research examined the effect of social exclusion on consumer preferences. Three experimental studies were conducted to test whether consumers experiencing social exclusion would choose specific kinds of purchases. The results of the three studies provided convergent support for the notion that consumers who feel socially excluded exhibit a preference for experiential purchases over material purchases. It therefore appears that experiential purchases can more effectively compensate for the relational needs caused by social exclusion. The effect was stronger for socially excluded individuals exhibiting more interdependent self‐construal than for those exhibiting a more independent self‐construal. These results indicate that social impact is an antecedent of experiential purchases, and they shed light on an important mechanism to alleviate the negative effects of social exclusion. 相似文献

We examined whether regulatory fit effects are asymmetric—namely, whether they occur only among individuals with a promotion focus or a prevention focus. We adopted a task where individuals make moral judgments of other-oriented lies and conducted three studies. The results indicated that prevention-focused individuals judged other-oriented lies based on a vigilant strategy as more moral than lies based on an eager strategy (Studies 1 and 2). Meanwhile for promotion-focused individuals, there were no differences between eager and vigilant strategies on moral judgments of other-oriented lies. Additionally, the results suggested that the feeling of rightness is an underlying mechanism of the regulatory fit effects of prevention focus (Study 3). 相似文献

特瑞尔·卡弗(Terrell Carver)是国际著名的马克思恩格斯学者,<马克思恩格斯全集>历史考订版(MEGA2)编委会委员.他改变传统考察顺序,独树一帜地提出"恩格斯一马克思问题",将恩格斯置于马克思主义理论研究的第一位,主张通过解读恩格斯来理解马克思.他声称反对"一致论"和"对立论",确立了自己的"差异论"立场,即在承认马克思与恩格斯有一致之处的同时努力寻找并指出他们的具体差异. 相似文献
