When study is spaced across sessions (versus massed within a single session), final performance is greater after spacing. This spacing effect may have multiple causes, and according to the mediator hypothesis, part of the effect can be explained by the use of mediator-based strategies. This hypothesis proposes that when study is spaced across sessions, rather than massed within a session, more mediators will be generated that are longer lasting and hence more mediators will be available to support criterion recall. In two experiments, participants were randomly assigned to study paired associates using either a spaced or massed schedule. They reported strategy use for each item during study trials and during the final test. Consistent with the mediator hypothesis, participants who had spaced (as compared to massed) practice reported using more mediators on the final test. This use of effective mediators also statistically accounted for some – but not all of – the spacing effect on final performance. 相似文献

The SPoARC effect (Spatial Positional Associated Response Codes) has only been observed in working memory (WM) using closed sets. It is interpreted as showing that individuals spatialise to-be-remembered items in a left-to-right fashion, using spatialisation as context. Given that context is crucial for episodic memory (EM), we tested if this effect could be observed in EM by using 15-word lists taken from an open set. After each list, 30 probes were sequentially displayed to test recognition. The left/right-hand key assignment for yes/no answers was varied. No SPoARC effect was observed. However, as all previous SPoARC experiments had used short lists and closed sets, it was not possible to know if this absence of SPoARC was due to the open set feature or the length of the lists. A second experiment was thus run using open sets and short 5-word lists, which do not necessitate EM to be remembered. A SPoARC effect was observed indicating that Experiment 1 result was due to the involvement of supra-span lists and that SPoARC effects do not extend to EM with open sets. Experiment 2 also enabled us to generalise the SPoARC effect to open sets in WM for the first time. 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

想/不想范式(Think/No-think,TNT)是基于go/no-go范式提出来的用于研究动机性遗忘过程的实验范式,主要过程是指个体对于记忆的提取抑制可以导致随后该记忆的遗忘。近年来TNT范式的大量行为学研究都一致性地发现记忆提取抑制可以产生负性控制效应,验证了在实验室情境下对动机性遗忘进行研究的可行性。其中,负性控制效应指的是压抑条件的项目相对于基线条件的项目的回忆量有显著降低。关于动机性遗忘发生的神经机制的探讨已积累了大量的研究证据,总结脑电(EEG)和功能核磁共振(f MRI)两个模态的研究,我们提出了动机性遗忘发生的多模态功能网络模型。最后,在该模型的基础上,我们展望了TNT范式未来的研究方向,其中特别注意到同步EEG-f MRI技术的应用有望为我们揭示出记忆提取抑制导致的动机性遗忘发生的动态过程。 相似文献

以大学生为被试,采用投射测验法分离出两类不同性质的内隐人格观,然后通过效价匹配实验和错觉关联实验,初步探讨了内隐人格观对他人知觉的信息加工模式的影响。研究结果表明:(1)跨性格、能力等不同人格属性有共通一致的内隐观;(2)固存观的反面就是渐变观,它们是同一维度的两极;(3)与渐变观者相比,固存观者更易以一种评价性方式知觉他人信息;同时,渐变观者不像固存观者那样对他人特质作出静态判断,而是集中注意力于理解他人行为发生的动态过程。 相似文献

采用眼动记录技术和恋人概念威胁启动范式探讨自我和恋人面孔优势效应的产生和维持过程。结果发现:与概念非威胁启动条件下相比,概念威胁启动条件下,被试搜索恋人面孔时的兴趣区个数和搜索自我面孔时的平均眼跳次数与搜索陌生人面孔时比差异变得不显著;恋人面孔与陌生人面孔在兴趣区内总注视时间上的差异变得不显著。结果表明,自我与恋人面孔存在注意的优先捕获和维持优势,恋人概念的威胁启动会减少对恋人的关注,证明了建立恋人的积极概念是恋人面孔优势效应产生和维持的重要原因。 相似文献

A Below‐Average Effect with Respect to American Political Stereotypes on Warmth and Competence 下载免费PDF全文
The “above‐average effect” is the phenomenon that people tend to judge themselves above average on desirable traits. Based on social identity theory, we propose that a “below‐average effect” may arise when individuals rate themselves and the average ingroup member on traits stereotypically associated with the ingroup. In two studies, Republican and Democrat participants rated themselves and the average political ingroup member on possession of desirable traits related to warmth and competence. Current political stereotypes in America associate the former dimension with Democrats and the latter with Republicans. Consistent with our hypothesis, the above‐average effect was moderated by political group and dimension in interaction. In particular, Democrats rated themselves below the average Democrat on warmth and Republicans rated themselves below the average Republican on competence. 相似文献

This study investigated differential item functioning (DIF) mechanisms in the context of differential testlet effects across subgroups. Specifically, we investigated DIF manifestations when the stochastic ordering assumption on the nuisance dimension in a testlet does not hold. DIF hypotheses were formulated analytically using a parametric marginal item response function approach and compared with empirical DIF results from a unidimensional item response theory approach. The comparisons were made in terms of type of DIF (uniform or non‐uniform) and direction (whether the focal or reference group was advantaged). In general, the DIF hypotheses were supported by the empirical results, showing the usefulness of the parametric approach in explaining DIF mechanisms. Both analytical predictions of DIF and the empirical results provide insights into conditions where a particular type of DIF becomes dominant in a specific DIF direction, which is useful for the study of DIF causes. 相似文献
