Frequently finding a target in the same location within a familiar context reduces search time, relative to search for objects appearing in novel contexts. This learned association between a context and a target location requires several blocks of training and has long-term effects. Short-term selection history also influences search, where previewing a subset of a search context shortly before the appearance of the target and remaining distractors speeds search. Here we explored the interactions between contextual cueing and preview benefit using a modified version of a paradigm from Hodsoll and Humphreys (Journal of Experimental Psychology: Human Perception and Performance, 31(6), 1346–1358, 2005). Participants searched for a T target among L distractors. Half of the distractors appeared 800 ms before the addition of the other distractors and the target. We independently manipulated the repetition of the previewed distractors and the newly added distractors. Though the previewed set never contained the target, repetition of either the previewed or the newly added context yielded contextual cueing, and the effect was greater when the previewed context repeated. Another experiment trained participants to associate the previewed context with a target location, then disrupted the association in a testing phase. This disruption eliminated contextual cueing, suggesting that learning of the previewed context was associative. These findings demonstrate an important interaction between distinct kinds of selection history effects.

This article reports on an experiment designed to test whether the cartoon manipulation leads to significant increases in aggressive thoughts and aggressive behaviors among Chinese children (n = 3,000). Results indicated that brief exposure to a violent cartoon triggered higher aggressive thoughts and aggressive behaviors than a nonviolent cartoon. Females displayed higher aggressive thoughts and aggressive behaviors than males in a nonviolent cartoon condition, while males displayed higher aggressive behaviors than females in a violent cartoon condition. Mediation analysis suggested that the effect on aggressive behaviors was mediated by aggressive thoughts. The findings imply that cartoon developers, parents, and teachers should develop cartoons that inhibit children's aggressive thoughts to avoid aggressive behaviors. Females are the key group for the prevention and intervention of aggression in a nonviolent cartoon context, while males are the key group for the prevention and intervention of aggression in a violent cartoon context.  相似文献

The aim of this study was twofold: first, to examine the lasting effects of working hours on later job performance and well-being (i.e. emotional exhaustion and work engagement); second, to delineate the protective role of psychological detachment in the highly demanding Chinese work setting featuring long working hours. We employed a panel design in which all variables were measured twice, with six months in between the waves. Data were obtained from 323 Chinese employees working in diverse industries in Taiwan. Analysing the panel data with structural equation modelling (SEM) techniques, we found that working hours were positively associated with emotional exhaustion and negatively associated with work engagement and job performance, measured six months later. Detachment moderated the effects of working hours on later work engagement and job performance. Specifically, detachment attenuated the negative relationships between working hours and work engagement and job performance. The present study extends the recovery research in the West by demonstrating the protective role of detachment in the East Asian societies with important managerial implications.  相似文献

手足口病重症、危重症常出现全身炎症反应综合征.全身炎症反应综合征发病机制有多种学说:细胞因子风暴说、正反馈说、促炎/抗炎因子平衡说等.本文根据免疫系统由固有性免疫与适应性免疫两部分组成及固有性免疫→抗原提呈→适应性免疫构成一个完整的免疫网络的已知理论,结合系统论、信息论、控制论观点对手足口病全身炎症反应综合征免疫学发病机制进行探讨,提出了“固有免疫代偿/失代偿”新学说.  相似文献

全真道戒律是全真教对教徒言行、思想的规定,是教徒在修行过程中必须遵守的行为准则,其内容具有丰富的伦理思想。这样一种具有伦理内涵结构的全真道戒律所产生的社会控制功能,笔者认为主要有三方面:(1)对个体的双重约束;(2)对教团组织的维系功能;(3)对国家法规的弥补功能。  相似文献

The relationships of Internet use, web communication, and sources of social support with adolescent self‐injurious thoughts and behaviors (SITBs) in Taiwan were investigated. The study sample of 391 12 to 18‐year‐olds was selected from nine public high schools. Findings show that girls are more likely to have SITBs, except for suicide gestures. Web communication is a risk factor for SITBs in boys but not in girls. Family support is protective in both genders. Support from friends is protective and support from significant others was a risk factor for suicide plans in girls. Support from virtual social communities can have both positive and negative effects on adolescent SITBs, with different effects by gender.  相似文献

《周易》作为群经之首,是中国文化的源头,中国学术的各个方面都深受其影响。中医学的奠基之作《内经》就是以易理为自己的世界观和方法论基础的。在中医学发展的早期,医与《易》的关系尚比较隐蔽,至明代则医与《易》的关系变得紧密而明显了。从《内经》至明代"医易学"的形成之间,作为金元四大家之集大成者的朱丹溪作了重要的准备性工作,本文对此略加分析。  相似文献
