This study employs a release of proactive interference technique to explore encoding‐related processes in social phobia. Twenty‐six individuals with social phobia and 24 individuals with panic disorder participated in the memory task. Significant release of proactive interference was found when neutral and threat dimensions were encoded, but not when social and physical threat dimensions, or when positive and threat dimensions were presented. Threat was therefore differently encoded depending on the active encoding context in which semantic processing occurred. Individuals with social phobia or panic disorder did not differ in the release of proactive interference. The present experiment consequently yields little support for the specificity hypothesis in memory of anxious individuals. Instead, the findings generally demonstrate that threat encoding is similar for people with social phobia and those with panic disorder.  相似文献

Deep learning is associated with the latest success stories in AI. In particular, deep neural networks are applied in increasingly different fields to model complex processes. Interestingly, the underlying algorithm of backpropagation was originally designed for political science models. The theoretical foundations of this approach are very similar to the concept of Punctuated Equilibrium Theory (PET). The article discusses the concept of deep learning and shows parallels to PET. A showcase model demonstrates how deep learning can be used to provide a missing link in the study of the policy process: the connection between attention in the political system (as inputs) and budget shifts (as outputs).  相似文献

While once the archetypical outsiders, most Jews today do not feel like outsiders in the United States. Using the 2001 National Jewish Population Survey, we examine the factors that differentiate those who feel like outsiders from those who do not. We find that feeling like an outsider is largely associated with having experienced anti‐Semitism, the number of Jews living nearby, the proportion of a respondent's friends’ that are Jewish, and whether Jews identify with some branch of Judaism versus those who identify as ethnic Jews. Although the effects of discrimination on feeling like an outsider are unsurprising, the smaller but persistent effect of geographic context deserves more attention. Jews feel less like outsiders when they live in places where they can and do have more contact with other Jews. The increased within‐group ties that are possible in areas of greater Jewish concentration appear to facilitate psychological integration into the larger community.  相似文献

As the religious landscape of the United States becomes increasingly diverse, understanding how individuals of different faiths relate to each other and the consequences of those relationships presents a significant issue for research. Research studying such faith‐bridging interactions has been limited and primarily focused on interfaith marriage. Using social network data from the 2004 General Social Survey we examine the dynamics underlying the frequency of interfaith ties of all types. We then analyze how interreligious ties differ in strength from intrareligious ties.  相似文献

This study informs community science, and seeks to narrow the research-to-practice gap, by examining how the interpersonal networks within a setting influence individuals' use of interventions. More specifically, it explores the role of two network mechanisms-cohesion and structural similarity-in urban elementary school teachers' use of interventions designed to improve academic and behavioral outcomes for students. Lagged regression models examine how position in advice giving networks influenced weekly use of the daily report card and peer assisted learning by kindergarten through fourth grade teachers in three schools. Results indicate that intervention use spreads among teachers with similar patterns of advice-giving relationships (i.e., via structural similarity), rather than from teachers who are sources of advice (i.e., via cohesion). These results are consistent with findings in other settings, and suggest that researchers wishing to increase the use of an intervention should select change agents based on their patterns of their relationships, rather than on their direct connections.  相似文献

The detrimental effects of power on confidence, advice taking, and accuracy   总被引:1,自引:0,他引:1  
Incorporating input from others can enhance decision quality, yet often people do not effectively utilize advice. We propose that greater power increases the propensity to discount advice, and that a key mechanism explaining this effect is elevated confidence in one’s judgment. We investigate the relationships across four studies: a field survey where working professionals rated their own power and confidence and were rated by coworkers on their level of advice taking; an advice taking task where power and confidence were self-reported; and two advice taking experiments where power was manipulated. Results consistently showed a negative relationship between power and advice taking, and evidence of mediation through confidence. The fourth study also revealed that higher power participants were less accurate in their final judgments. Power can thus exacerbate the tendency for people to overweight their own initial judgment, such that the most powerful decision makers can also be the least accurate.  相似文献

Using longitudinal data on 343 young adults, the present study investigated the social ties involved in young adults’ work-related goals, how these ties change during transition to working life, and whether social ties contribute to success in dealing with the transition. The results showed that goal-relevant social ties reflected changes in the young adults’ developmental context. Furthermore, social ties that included a person with high socioeconomic status and weaker social ties contributed to employment success, whereas social ties containing one’s supervisor were associated with quality of employment. The results also showed that goal-related social hindrance increased young adults’ intentions to quit and decreased job satisfaction.  相似文献

The present study examined 33 teams with a total of 206 team members (excluding team leaders) to explore the effects of intrateam guanxi and trust networks on individual effectiveness in Taiwan. Guanxi networks included non-job, departmental and past team networks, while trust networks included affective and cognitive trust networks. Results showed that: (i) guanxi networks could better explain members' effectiveness compared with relational demography, and different guanxi networks had different effects; (ii) the more central an individual's position was in the cognitive trust network, the higher the individual's effectiveness; (iii) the past team guanxi network of a team member displayed a positive effect on the centrality of cognitive trust network, while non-job and departmental guanxi networks showed negative effects; and (iv) the effects of members' guanxi networks on individual effectiveness were mediated by the centrality of trust networks.  相似文献

万拉法新对抑郁症注意网络功能的影响   总被引:2,自引:0,他引:2  
杜静  汪凯  董毅  范津 《心理学报》2006,38(2):247-253
目的 研究抑郁症的注意网络状况及抑制神经递质再摄取的药物万拉法新对其的影响,探索神经递质与注意网络的关系。方法 对32例应用万拉法新治疗的抑郁症患者治疗前及疗后6周进行注意网络测定和临床症状评分。结果 与正常组比较,抑郁组的警觉网络和执行控制网络效率差异有显著性,定向网络效率差别无显著性。警觉网络效率与HAMD评分的睡眠障碍因子分呈负相关。治疗后,抑郁组的警觉效率显著增加,其改善与睡眠障碍的好转呈正相关。执行控制网络效率,平均反应时和临床症状评分均较治疗前显著降低,定向网络效率无变化。结论 抑郁症患者存在警觉和执行控制注意网络的异常,万拉法新可选择性地改善警觉和执行控制注意网络的异常而不影响其定向网络  相似文献
