Decades of research suggest that encoding information with respect to the self improves memory (self-reference effect, SRE) for items (item SRE). The current study focused on how processing information in reference to the self affects source memory for whether an item was self-referentially processed (a source SRE). Participants self-referentially or non-self-referentially encoded words (Experiment 1) or pictures (Experiment 2) that varied in valence (positive, negative, neutral). Relative to non-self-referential processing, self-referential processing enhanced item recognition for all stimulus types (an item SRE), but it only enhanced source memory for positive words (a source SRE). In fact, source memory for negative and neutral pictures was worse for items processed self-referentially than non-self-referentially. Together, the results suggest that item SRE and source SRE (e.g., remembering an item was encoded self-referentially) are not necessarily the same across stimulus types (e.g., words, pictures; positive, negative). While an item SRE may depend on the overall likelihood the item generates any association, the enhancing effects of self-referential processing on source memory for self-referential encoding may depend on how embedded a stimulus becomes in one’s self-schema, and that depends, in part, on the stimulus’ valence and format. Self-relevance ratings during encoding provide converging evidence for this interpretation. 相似文献

在西方文化背景下提出的时间自我评价理论认为,人们为了维护当前积极自尊,主观上会远离过去失败而亲近过去成功。本研究采用线段评估法,选取311名中国大学生被试,通过两个实验考察自尊水平、事件效价与时距对过去事件时距估计的影响,以检验该理论的文化普适性。结果表明:对过去事件的时距估计,自尊水平、事件效价及其交互作用在同一时距里均不存在显著差异;时距的主效应及其与事件效价的交互作用均显著,在负效价水平上存在显著时距差异,在正效价水平上无显著时距差异。研究结果不支持基于西方文化背景下的时间自我评价理论。 相似文献

通过3个实验考察语音反应方式下情绪效价对空间Simon效应的影响。实验1采用空间Simon任务范式考察语音反应方式下空间Simon效应的存在;实验2增加刺激的情绪效价维度,采用同样任务考察无关情绪效价对空间Simon效应的影响;实验3在实验2基础上进一步探讨当情绪效价为相关维度时对空间Simon效应的影响。研究结果表明:语音反应方式下,只有当情绪效价为相关维度时,才会对空间Simon效应产生影响,且该影响主要表现在积极效价对认知控制的促进作用而导致空间Simon效应减小或消失,此结果与极性编码一致性假说一致,也拓宽了躯体特异性假说,扩展了以往对情绪影响空间认知的理解。 相似文献

本文从情绪的效价载荷及其脑功能成像研究、面部表情的识别及其脑功能成像研究以及情绪的诱发及其脑功能成像研究等三方面介绍了情绪加工的脑机制及其研究现状。从现有的研究成果来看,大脑皮层在加工不同效价载荷的情绪时具有很大的重叠性;有关面部表情识别的研究表明,不同的神经环路负责调节对不同面部表情的反应;有关诱发的情绪的研究表明,前扣带回皮层在表征实验诱发的情绪时扮演着一个非常重要的角色。文章最后指出了情绪研究目前面临的一些问题,并指出在我国开展情绪的脑机制研究的重要意义。 相似文献

One prestudy based on a corpus analysis and four experiments in which participants had to invent novel names for persons or objects (N?=?336 participants in total) investigated how the valence of a face or an object affects the phonological characteristics of the respective novel name. Based on the articulatory feedback hypothesis, we predicted that /i:/ is included more frequently in fictional names for faces or objects with a positive valence than for those with a negative valence. For /o:/, the pattern should reverse. An analysis of the Berlin Affective Word List – Reloaded (BAWL-R) yielded a higher number of occurrences of /o:/ in German words with negative valence than in words with positive valence; with /i:/ the situation is less clear. In Experiments 1 and 2, participants named persons showing a positive or a negative facial expression. Names for smiling persons included more /i:/s and fewer /o:/s than names for persons with a negative facial expression. In Experiments 3 and 4, participants heard a Swahili narration and invented pseudo-Swahili names for objects with positive, neutral, or negative valence. Names for positive objects included more /i:/s than names for neutral or negative objects, and names for negative objects included more /o:/s than names for neutral or positive objects. These finding indicate a stable vowel-emotion link. 相似文献

Accumulating evidence suggests that emotional information is often recognised faster than neutral information. Several studies examined the effects of valence and arousal on word recognition, but yielded partially diverging results. Here, we used two alternative versions of a constructive recognition paradigm in which a target word is hidden by a visual mask that gradually disappears, to investigate whether the emotional properties of words influence their speed of recognition. Participants were instructed either to classify the incrementally appearing word as emotional or non-emotional (semantic categorisation task) or to decide whether the appearing letter string is an existing word or not (lexical decision task). Results from both tasks revealed faster recognition times for high- compared to low-arousing words, and for positive compared to negative or neutral words. These findings indicate a recognition advantage for emotionally positive and highly arousing stimuli that persists even when visual word recognition is hampered and participants are encouraged to make more active, semantic inferences to generate the meaning of the emerging word. 相似文献

评价性条件反射(Evaluative Conditioning, EC)指通过将一个中性刺激和一个情绪性刺激重复配对, 使中性刺激获得情绪性刺激的情感性评价。条件联结觉察(Contingency Awareness)指被试觉察到中性刺激和情绪性刺激的配对规律。当前, 条件联结觉察在EC中的作用尚存争议。一些研究证明, 条件联结觉察独立于EC, 甚至阻碍了EC; 另一些研究则表明, 条件联结觉察促进EC的发生; 还有些研究发现条件联结觉察在EC中的作用受其他变量的调节。因此, 在将来的研究中, 需发展出更准确的觉察测量、检验其他变量的调节作用、加强多感觉通道的EC研究、探索EC的加工机制。 相似文献

检验了情绪的效价和确定性评价对个体的信息加工策略选择的影响及其心理机制。结果表明,情绪效价对个体的信息加工方式的影响会受到情绪确定性评价的调节。高确定评价的情绪中,积极情绪的被试更倾向于采用启发式加工,消极情绪的被试更倾向于采用系统式加工。积极情绪中,高确定评价情绪的被试更倾向于采用启发式加工,低确定评价情绪的被试更倾向于采用系统式加工。当个体对自己产生情绪的原因进行合理归因后,情绪效价和确定性评价对个体信息加工方式的影响效应都消失了,说明情绪的效价和确定性评价均以信息的方式对对个体信息加工策略的选择产生影响。 相似文献

用设置故事情景的方法对儿童对他人情绪与过去经验的关系的认知进行了实验研究。研究表明,4~7岁儿童能够认知他人情绪与过去经验的关系,认知能力随年龄的增长不断提高。情绪效价和情绪情景的匹配性影响儿童对他人情绪与过去经验关系的认知。4、5岁儿童更能认识到正性情绪情景条件下体验到负性情绪的他人情绪与过去经验的关系,其得分显著高于其它情绪情景故事和行为故事。 相似文献
