焦虑与注意偏向的研究是近年来情绪与认知领域的热点。为探讨特质焦虑个体的注意偏向特点及其返回抑制能力是否受不同线索的调节, 采用特质焦虑量表筛选高特质焦虑大学生29名, 低特质焦虑大学生28名完成线索-靶子任务。要求被试在提示线索消失后, 对位置进行快而准地辨别反应, 分别探索中性和情绪性提示线索下被试的返回抑制。结果发现:(1)在中性线索条件下, 高焦虑个体平均反应时慢于低焦虑个体。(2) 在情绪线索条件下, 高焦虑个体在负性线索下的反应时小于在正性线索下的反应时; 高、低焦虑个体在各种SOA条件下均出现了返回抑制, 但各组返回抑制量受到情绪线索的调节:在正性情绪线索条件下, 两组返回抑制量没有显著差异; 在负性情绪线索下, 高焦虑个体返回抑制量显著小于低焦虑个体。这表明, (1)焦虑个体的注意偏向受到刺激信息的影响:只对负性情绪线索出现注意警觉; (2)只有在涉及负性情绪信息时高、低焦虑个体返回抑制能力才有差异, 高焦虑个体存在对负性情绪线索的抑制困难。 相似文献

Abstract The role of work characteristics in determining return to work after an acute coronary event was examined. One hundred and forty nine patients were enrolled. One year post-discharge, 74 had returned to work. Work characteristics (decision latitude, and opportunity for social interaction at work), together with age, depression, and medical prognosis, correctly classified work status in 78% of cases. At 12 months post-discharge, patients who had not returned to work recorded significantly poorer levels of adjustment compared to those who had returned to work. A better quality of life is associated with a lower level of depression pre-hospitalization, ownership of a larger home, being male, and having a more positive work environment. The findings suggest that the pre-illness work environment of the patient is a factor influencing return to work, which needs to be considered in rehabilitation programmes. 相似文献

We examined the effects of cue luminance on visual orienting. Experiment 1 established that the commonly-found early facilitation and late inhibition of return (IOR) effects were independent of cue luminance with single cues in terms of their amplitude, although IOR was delayed in the low compared to the high luminance cue condition. In contrast, Experiment 2 revealed that, with dual cues of mixed luminance, both facilitation and IOR effects were found only with bright cues. When cues had equal luminance, however, there were cueing effects for two cued locations but only when the cues were bright. The data were accommodated in a neural network model of biased competition in which cueing effects emerge at more than one location provided input activation is sufficient to overcome competitive damping of the selection system. 相似文献

ABSTRACTHumans routinely perform visual search towards targets to adapt to the environment. These sequences of ballistic eye movements are shaped by a combination of top–down and bottom–up factors. Recent research documented that human observers display cultural-specific fixation patterns in a range of visual processing tasks. In particular, eye movement strategies extracting information from faces clearly differs between Western Caucasian (WC) and East Asian (EA) observers. However, whether such cultural differences are also present for visual scene processing remains debated. To this aim, we recorded the eye movements of WC and EA observers while they were solving visual search problems parametrically varying in difficulty: Where’s Waldo. Both groups had a comparable familiarity with the Waldo books reaching a comparable level of accuracy in target detection. Both cultural groups also showed a comparable temporal effect on inhibition of return, with longer fixation durations when saccades were performed to a return location compared to other locations. Westerners, however, located Waldo faster than Easterners. Interestingly, this modulation of speed was likely related to differences occurring on the low-level mechanisms of spatial inhibition of return, with EA observers returning more often to previously visited locations than the WC observers. This suboptimal eye movement strategy in the Easterners might be engendered by their cultural perceptual bias consisting in? a greater use of extra-foveal information. Overall, our data point towards the existence of a subtle, but significant difference in the processing of visual scenes across observers from different cultures during active visual search. 相似文献

前、后注意网络的关系--返回抑制和Stroop干扰效应 总被引:1,自引:0,他引:1
将IOR范式与Stroop任务相结合,试图从探讨IOR与Stroop干扰效应之间的关系来推测AAN和PAN之间的关系以及IOR与注意之间的关系。结果表明,在控制条件下出现了显著的IOR,在Stroop条件下没有出现明显的IOR;提示和非提示位置上均出现了显著的Stroop干扰效应,但提示位置上的干扰量要显著低于非提示位置。从IOR和Stroop干扰效应之间的关系可推知,PAN和AAN是两个有交互影响的注意网络,AAN对PAN有压制作用,而PAN对。AAN也有一定的影响。最后,作者对返回抑制与注意问的关系进行了深入的讨论。 相似文献

Institutional religious involvement wanes during young adulthood, but evidence suggests life‐course factors such as family formation bring people back to religion. Using the National Longitudinal Study of Adolescent to Adult Health (Waves 1, 3, and 4), we examine how often young adults who were involved in institutional religion as adolescents return—measured by religious service attendance and religious affiliation—after leaving in emerging adulthood, and how this return is patterned by family formation. The majority of young adults who leave do not return to regular religious service attendance, regardless of their family formation. But single parents, married parents, and childless married individuals are more likely, and childless cohabiting couples less likely, to return to religious communities than those who are both single and childless. Only married parents are more likely than childless singles to reaffiliate, though there is marginal evidence that childless married adults may also be more likely. Thus, the institutions of religion and family are still linked, even though overall levels of religious return are not as high as expected. 相似文献

There are three distinct patterns of migration among Chinese migrant children: whole‐family, single‐parent‐first, and both‐parents‐first migration. This study investigated the life satisfaction of children who migrated under the different migration patterns and examined the mediating role of family functioning in the relationship between the children's migration patterns and their life satisfaction. Participants consisted of migrant children (N = 703) from primary and junior middle schools in Chengdu, China. The results showed that (a) migrant children from the whole‐family and single‐parent‐first patterns of migration reported greater life satisfaction than did those from the both‐parents‐first pattern, and (b) family functioning partially mediated the association between migration patterns and life satisfaction. The present study highlights the importance of avoiding separation of children from both parents during migration and the need to develop interventions for migrant children's psychological adaptation by improving their families’ functioning. 相似文献

This review article provides an overview of the British Academy Project on ‘Forced Migration, Religious Diplomacy and Human Security in the Eastern Orthodox World’ (January–December 2018), research questions, methodology, main findings and policy recommendations. The project compared the ways in which religious communities engaged with forced displaced populations in Eastern Europe and former Soviet states, with a particular focus on Serbia and Ukraine, collected a dataset on ‘Eastern Orthodoxy and Human Security’ and organised two workshops in Belgrade and Kyiv. 相似文献
