错误记忆具有可植入性。植入性错误记忆常常与真实记忆发生混淆, 成为个体经验的一部分, 进而影响人们的思想、态度和行为。植入错误记忆的范式主要有错误反馈技术、想象膨胀、照片修改范式以及盛情-欺骗范式。研究表明, 植入性错误记忆发生在饮食、消费以及攻击行为等活动中。植入性错误记忆与真实记忆的辨别主要包括结果、情绪、持续性以及生理机制四个方面。植入性错误记忆的解释主要有联结观和多阶段模型。目前研究存在许多问题, 包括要求特征、认知反应、范式选取以及实验伦理等。未来研究需要对植入错误记忆方法的有效性、个体特征与错误记忆植入的匹配、植入性错误记忆行为结果的测量以及实际应用等进行探讨。 相似文献

时间压力是现代社会中人们经常面对的重要问题。以往研究认为时间压力只会产生消极影响, 然而现有研究发现时间压力也会产生积极影响。总结以往研究, 介绍了时间压力的概念和测量方式, 分别阐述了时间压力的损耗作用和促进作用, 并用注意焦点理论、激活理论、维生素模型和挑战?阻碍模型等理论解释时间压力的双刃效应。未来研究应该进一步关注:(1)基于时间心理账户开展时间压力的分类研究; (2)时间压力促进作用的动机和情绪双路径机制; (3)探寻有效缓解时间压力损耗作用的机制。 相似文献

采用事件相关电位技术和三类刺激的经典oddball范式,以内隐的方式探讨内倾特质个体的自我参照加工程度效应及其神经机制。实验发现,在P2的波幅上,在电极前部、前中部和中部位置高自我相关的刺激比其它刺激诱发了更大的P2波幅。在P2的潜伏期上,在电极前部、中部、和中后部位置高自我相关的刺激比其它刺激诱发了更短的潜伏期。在N2的波幅上,高自我相关名字比其它刺激在左脑所诱发了更大的P2的波幅;对比内倾型被试,中间型被试的高自我相关名字比其它刺激诱发了更大的N2的波幅。在N2的潜伏期上,高自我相关的刺激在全脑都比其它刺激诱发了更短的N2潜伏期,且中后部电极位置的潜伏期最短;两类人格被试的高自我相关名字比其它刺激诱发了更短的N2潜伏期,但中间型人格被试的潜伏期最短。在P3平均波幅上,高自我相关的刺激在全脑都比其它刺激诱发了更大的P3波幅,其中中部脑区效应最大。研究结果表明内倾特质个体的自我参照加工具有程度效应,但对比中间型个体,内倾特质个体的自我参照加工的程度效应更弱。 相似文献

Eight pigeons responded in a concurrent-chains procedure in which terminal-link schedules changed pseudorandomly across sessions. Pairs of terminal-link delays either summed to 15 s or to 45 s. Across sessions, the location of the shorter terminal link changed according to a pseudorandom binary sequence. On some terminal links, food was withheld to obtain start and stop times, measures of temporal control. Log initial-link response ratios stabilized within the first half of each session. Log response ratio was a monotonically-increasing but nonlinear function of programmed log terminal-link immediacy ratio. There was an effect of absolute terminal-link duration on log response ratio: For most subjects, preference for the relatively shorter terminal-link delay was stronger when absolute delays were long than when absolute delays were short. Polynomial regressions and model comparison showed that differences in degree of nonlinearity, not in sensitivity to log immediacy ratio, produced this effect. Temporal control of stop times was timescale invariant with scalar variability, but temporal control of start times was not consistent across subjects or terminal-link durations. 相似文献

Evaluating mediation and moderation effects in school psychology: A presentation of methods and review of current practice 总被引:2,自引:0,他引:2
Third variable effects elucidate the relation between two other variables, and can describe why they are related or under what conditions they are related. This article demonstrates methods to analyze two third-variable effects: moderation and mediation. The utility of examining moderation and mediation effects in school psychology is described and current use of the analyses in applied school psychology research is reviewed and evaluated. Proper statistical methods to test the effects are presented, and different effect size measures for the models are provided. Extensions of the basic moderator and mediator models are also described. 相似文献

Most theoreticians believe that reading habits explain why Western adults associate small numbers with left space and large numbers with right space (the SNARC effect). We challenge this belief by documenting, in both English and Hebrew, that SNARC changes during reading: small and large numbers in our texts appeared near the left or right ends of the lines, positioned either spatially congruent or incongruent with reading habits. In English, the congruent group showed reliable SNARC before and after reading and the incongruent group’s SNARC was significantly reduced. In Hebrew the incongruent reading condition even induced a reverse SNARC. These results show that SNARC is a fleeting aspect of number representation that captures multiple spatial associations. 相似文献

When primed by backward-masked, target-like stimuli, discrete responses (e.g. button presses) to simple visual targets can be slower when prime and target match (compatible) than when they do not (incompatible). The current study investigated the nature of the stimulus–response mapping underlying this negative compatibility effect (NCE). Discrete left–right responses to arrow targets were primed with arrows oriented in one of 16 directions. Responses were either a standard button press or a 10 cm movement on a graphics tablet. Both tasks showed an identical NCE; importantly, reaction times in both tasks decreased smoothly as the angular distance between prime and target increased (i.e. as compatibility decreased), with the largest NCE evident between the extreme cases (prime-target distances of 0° and 180°). Primes exerted an effect on the required response in proportion to the amount of overlap (reflecting population vector coding). The mapping between the priming stimulus and response is continuous, not categorical. 相似文献

时间情景模型提取过程的实质初探:激活与抑制 总被引:1,自引:0,他引:1
采用扇效应技术和负启动实验范式探讨时间情景模型提取过程的实质。实验材料为18个"某人在某时间做某事"的句子,结果发现,实验条件下目标句的反应时显著长于控制条件下目标句的反应时,而两种条件下启动句的反应时无显著差异,出现了显著的负启动效应。这表明,在时间情景模型提取过程中,不仅激活了目标情景模型和与之相关的情景模型,而且对同时激活的相关的情景模型进行了抑制,支持长时记忆提取的抑制观。 相似文献

In six experiments, we tested four explanations for the better/worse-than-average effect (B/WTA) by manipulating the number of items comprising the target or referent of direct comparison. A single-item target tended to be rated more extremely than a single-item or a multi-item referent (Experiments 1–3). No B/WTA was obtained, however, when a multi-item target was compared with either a single- or multi-item referent (Experiments 4 and 5). A bias favoring a multi-item target was found only if cohesiveness among the items was increased through instructions (Experiment 6). The Unique-Attributes Hypothesis generally provided the best explanation the findings; the focalism explanation also demonstrated some empirical viability. The results suggest that important preferential decision-making outcomes can be affected by both the number of items and whether items are strategically manipulated to serve as targets or referents of comparison. 相似文献
