以往研究认为内隐记忆具有不受干扰影响的自动化加工特征,其证据主要来自于对内隐记忆编码过程的研究。最近已有多项研究发现,内隐记忆受提取过程中的干扰影响,但对这一现象的产生机制目前仍尚无定论。本研究根据任务转换相关理论,通过将go/no-go范式引入干扰任务,探讨提取过程中前置干扰对内隐记忆产生影响的内在机制。结果表明,前置的干扰任务产生惯性激活时,后续的内隐记忆任务会受到影响,即启动效应降低。对惯性激活进行抑制后,随后的内隐记忆则不受影响。并且,在内隐记忆相关的N400成分上得到了与行为数据一致的结果,即在no-go干扰下,获得的N400新旧效应,在go干扰下却未被发现。研究结果证明,提取干扰对内隐记忆的影响主要由干扰任务与内隐记忆任务对认知资源的竞争导致。 相似文献

Drawing on cue consensus theory and status characteristics theory, we argue that the consensus between newcomer voice (challenging vs. supportive) and organizational culture (individualistic vs. collectivistic) leads to observers' social cognition of warmth or competence. Based on two survey studies and two experiment studies, we found that individualistic organizational culture strengthens the positive relationship between challenging voice and perceived competence and that voice constructiveness mediates this moderating effect. We also found that collectivistic organizational culture strengthens the positive relationship between supportive voice and perceived warmth, and prosocial motivation mediates this moderating effect. Focusing on consistent cues between voice and organizational culture, our research contributes to the voice literature, answering when and how both newcomer challenging voice and supportive voice can lead to perceived warmth and competence. Our results offer both theoretical implications and practical insights for employees and organizations. 相似文献

观察表明,群体隔离(10—12周)的大白鼠,在开阔地方的自由活动和杀小鼠行为方面没受到明显影响,但隔离鼠在电击后格斗行为明显地增加了。隔离鼠脑内单胺类种经介质的含量无明显改变。在电击格斗后群居组和隔离组脑内DA含量均明显降低。群居组鼠端脑内NE含量增高,脑干内5-HIAA含量降低,但隔离组无上述改变。隔离鼠在注利血平、电击后格斗行为明显减少。对上述现象进行了讨论。 相似文献

A driving simulator was used to examine the effects on driving performance of auditory cues in an in-vehicle information search task. Drivers' distraction by the search tasks was measured on a peripheral detection task. The difficulty of the search task was systematically varied to test the distraction caused by a quantified visual load. 58 participants completed the task. Performance on both search tasks and peripheral detection tasks was measured by mean response time and percent error. Analyses indicated that in-vehicle information search performance can be severely degraded when a target is located within a group of diverse distractors. Inclusion of an auditory cue in the visual search increased the mean response time as a result of a change in modality from auditory to visual. Inclusion of such an auditory cue seemed to influence distraction as measured by performance on the peripheral detection task; accuracy was lower when auditory cues were provided, and responses were slower when no auditory cues were provided. Distraction by the auditory cue varied according to the difficulty of the search task. 相似文献

In a field study involving university students from Canada and Japan, we tested hypotheses from the theory of uncertainty
orientation (Sorrentino and Roney in The uncertain mind: Individual differences in facing the unknown. Psychology Press, Philadelphia 2000). Consistent with previous research, those possessing an uncertainty orientation that matched their culture’s predominant
style of uncertainty regulation perceived a better student-classroom fit than those who did not match their culture’s predominant
style of uncertainty regulation. More importantly, we predicted and found that actual course grades varied as a function of
the culture’s style of uncertainty regulation in interaction with the participant’s uncertainty orientation and achievement-related
motives. Implications of these findings and applied relevance are discussed. 相似文献

Previous studies explain loss aversion as the result of a situation in which the expected negative emotions derived from a potential loss exceed the expected positive emotions derived from a potential gain (subtractive logic). We questioned this view and proposed additive logic, in which a linear combination between negative and positive emotions can be used as summed anticipatory affect intensity (SAAI) to explain loss aversion. By disproving two implicit hypotheses of subtractive logic, Study 1 showed that the additive logic of expected positive and negative affect was more effective than the subtractive logic in predicting loss aversion. Study 2 used real monetary gains and losses to verify the conclusion in Study 1. Using state‐trait theory to comprehensively consider the state and trait aspects of affect intensity, we further deduced that the immediate expected affect intensity might originate from the difference of an individual trait in affect intensity. Study 3 proved this hypothesis and showed that SAAI plays an intermediary role between affect intensity and loss aversion. Furthermore, Study 4 used real gamblers in casinos in Macau as its sample and obtained the same conclusion regarding loss aversion in real life as was found in the laboratory. Finally, we explained the effect of SAAI on loss aversion and indicated the contribution and significance of this study. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

采用感知教师支持、学习投入、学业自我效能感和成就目标定向问卷对498名高中生进行问卷调查,探讨感知教师支持对学习投入的影响,以及学业自我效能感和成就目标定向的链式中介效应。结果显示:(1)感知教师支持能通过学业自我效能感间接预测高中生学习投入,感知教师支持可以通过掌握趋近、表现趋近、表现回避间接预测高中生学习投入;(2)学业自我效能感→掌握趋近、学业自我效能感→表现趋近、学业自我效能感→表现回避三者分别在感知教师支持与学习投入之间起链式中介作用,学业自我效能感→掌握回避的中介效应则不显著。上述结果表明,感知教师支持不仅能分别通过学业自我效能感、掌握趋近、表现趋近、表现回避预测高中生学习投入,还能通过学业自我效能感和成就目标定向的链式中介作用间接预测高中生学习投入。 相似文献
