纯粹接触效应是指个体接触一个刺激的次数越频繁,个体对该刺激就越喜欢的现象。本文通过两个实验考察刺激的呈现次数与位置对纯粹接触效应的影响。实验1讨论了纯粹接触效应与刺激呈现次数之间的关系,发现刺激的偏好程度和再认成绩在不同的刺激呈现次数水平上都具有显著性差异。实验2讨论了纯粹接触效应与刺激呈现位置之间的关系,结果发现不同呈现位置上刺激的偏好程度不具有显著性差异,而再认成绩之间具有显著性差异。 相似文献

20世纪, 许多心理学家从“厄运与苦难”视角研究人晚年遭遇的身体、认知和情绪衰老, 但是近年的理论与实证研究从“老化悖论”——老年人情绪加工的积极效应——视角挑战这一“定论”。积极效应指老年人认知加工过程中比年轻人更偏好正性而非负性材料的现象。第二代社会情绪选择理论包括积极效应理论、认知控制假说和强弱整合模型3个关于认知和情绪功能年龄差异的理论模型, 特别强调了认知控制在老年人积极情绪加工中的潜在作用, 而自动化加工与控制性加工的区分则取决于注意资源配置。因此, 认知控制在老年人对积极情绪的注意加工中起重要作用。此外, 注意偏向的时间进程也是影响老年人情绪注意中积极效应的关键因素。最后, 综合以往研究构建出认知控制对老年人积极效应发生作用的注意阶段模型。未来研究可从中国老年人情绪注意加工模式、不同认知控制子成分的作用机制、提高研究生态学效度和注意的治疗品质几个方面继续探索。 相似文献

纯粹接触效应指刺激的重复呈现能增加个体对该刺激的喜好。该研究考察中性和负性情绪的非新异刺激能否产生纯粹接触效应。首先评定挑选出本身不使人产生偏好倾向的中性和负性词对。实验一、二分别以所选中性词和负性词为材料, 每个词阈下呈现6次或1次, 后进行偏好判断和再认判断。结果发现, 对多次接触的中性词,偏好分数显著高于随机水平, 再认成绩与随机水平无显著差异; 对多次接触的负性词, 偏好分数和再认成绩均与随机水平相比无显著差异。研究表明, 在阈下呈现的条件下, 中性的非新异刺激能产生经典纯粹接触效应, 而负性非新异刺激则无此种效应。负性情绪材料纯粹接触效应的这一特异性可用加工水平模型解释。 相似文献

前瞻记忆是指现在对将来某一段时间要做的行为的记忆。采用情绪图片作为诱发材料,研究了在情绪刺激下前瞻记忆任务以及前瞻记忆TAP效应的影响。结果表明:不同情绪效价主效应显著,正性情绪组成绩显著高于中性情绪组和负性情绪组; 前瞻记忆TAP效应在正性情绪和中性情绪下显著,负性情绪下部分显著; 在不同情绪效价影响下,语义—语义组、语义—知觉组、知觉—知觉组以及知觉—语义组的前瞻记忆成绩差异均存在统计学意义。 相似文献

视觉工作记忆中(VWM)已稳定存储的表征,依然会受内部注意选择的影响,说明内部注意选择对VWM发挥重要作用。本文首先阐述该领域主要的研究方法,然后对VWM中内部注意选择的效果和四个特性:时程、对象、容量和可持续性,以及其背后可能的理论机制和神经机制进行分析和总结。并据此从VWM的存储结构、内部注意的产生机制和处理方式等方面,为未来研究提出方向和建议。 相似文献

Mere ownership effect is the phenomenon that people tend to value what they own more than what they do not own. This classic effect is considered robust, yet effect sizes vary across studies, and the effect is often confused for or confounded with other classic phenomena, such as endowment or mere exposure effects. We conducted a pre-registered meta-analysis of 26 samples published before 2019 (N = 3024), which resulted in psychological ownership on valuing effect of g ∼ 0.57 [0.46, 0.69]. Suggestive moderator analyses supported the use of replica as the strongest moderators. Mere ownership effects were different from the null across all moderator categories and in most publication bias adjustments. We consider this as suggestive evidence that psychological owning leads to valuing, yet caution that much more research is needed.

Gotoh, F., Kikuchi, T. &Olofsson, U. (2010). A facilitative effect of negative affective valence on working memory. Scandinavian Journal of Psychology, 51, 185–191. Previous studies have shown that negatively valenced information impaired working memory performance due to an attention‐capturing effect. The present study examined whether negative valence could also facilitate working memory. Affective words (negative, neutral, positive) were used as retro‐cues in a working memory task that required participants to remember colors at different spatial locations on a computer screen. Following the cue, a target detection task was used to either shift attention to a different location or keep attention at the same location as the retro‐cue. Finally, participants were required to discriminate the cued color from a set of distractors. It was found that negative cues yielded shorter response times (RTs) in the attention‐shift condition and longer RTs in the attention‐stay condition, compared with neutral and positive cues. The results suggest that negative affective valence may enhance working memory performance (RTs), provided that attention can be disengaged. 相似文献

To evaluate the role of emotional valence on the impact of mind wandering on working memory (WM) and sustained attention, we reanalyzed data from three independently conducted studies that examined the impact of stress on WM (Banks & Boals, 2016; Banks, Welhaf, & Srour, 2015) and sustained attention (Banks, Tartar, & Welhaf, 2014). Across all studies, participants reported the content of their thoughts at random intervals during the WM or sustained attention task. Thought probes in all studies included a core set of response options for task-unrelated thoughts (TUTs) that were negatively, positively, or neutrally emotionally valenced. In line with theories of emotional valenced stimuli on capture of attention, results suggest negatively valenced TUTs, but not positively valenced TUTs, were related to poorer WM and sustained attention in two studies. Neutral TUTs were related to poorer WM but not sustained attention performance. Implications for models of mind wandering are discussed. 相似文献

自我参照范式是探索自我认知发展的重要范式,找到一个可靠方法获得一份稳定结果一直是儿童研究的重点和难点。研究以3岁至5岁儿童作为研究对象,通过所有权参照进行编码、图片再认和源判断进行检测。为了结果的稳定可靠,每位儿童需要参加4次测验。结果显示,图片再认上4岁、5岁儿童出现自我参照效应,源判断上3岁、4岁儿童出现自我参照效应。对源判断结果分析发现,自我参照成绩在各年龄组间保持不变、他人参照成绩随年龄增长逐渐提高,二者发展趋势的差异是5岁儿童源判断上没有自我参照效应的主要原因。以上结果说明,3~5岁儿童普遍存在自我参照效应,但测验方法会影响该效应的表现年龄;其次,自我源判断能力的发展早于他人,3~5岁之间他人源判断能力是在持续提高的;另外,4次测验间的比较证明,源判断测验较之再认具有更好的稳定性。 相似文献

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

采用项目法定向遗忘研究范式,在两个实验中分别使用情绪性语词和图片材料,考察主观努力程度影响情绪材料定向遗忘的心理机制。研究采用2(语词或图片情绪效价:正词/负词)×2(指示符:记住/忘记)×3(努力程度:20%/60%/100%)的被试内设计,因变量为情绪性语词或图片的再认率和定向遗忘效应。结果表明,正效价词在三种努力程度忘记条件的再认率无差别,而越努力去忘记负效价词,反而越能记住;正负效价的图片材料都呈现出越努力去忘记反而越能记住的特点。以上结果表明,语词与图片分别适合有意识加工和无意识加工,记住指令导致对情绪性语词和图片的选择性复述,符合选择性复述/被动衰退理论,而不同努力程度的忘记指令又引发了对情绪性语词和图片的主动抑制,符合注意抑制/执行控制理论。 相似文献
