Many studies have shown the benefits for long term retention of repeated retrieval during learning in verbal tasks, but few have shown its effectiveness using nonverbal materials. The aim of this study was to examine whether the retention benefits of repeated retrieval extend to preschool children performing a spatial location memory task. In this task, the children first studied where eight small toys were located in a partitioned box. Then, in the repeated retrieval condition, the children were asked to put each one of the toys in its place by themselves three times successively with feedback, whereas in the repeated study condition, they were asked to put each toy in its place with the experimenter showing them the correct location. Half of the children were then immediately tested and the remaining half tested after one day. The results showed that the 5 and 6 year old children in the retrieval condition retained location memory for the toys longer than those in the study condition in a memory task involving spatial content and enactment components. These findings have deep theoretical implications for the critical role of retrieval effort in long-term retention, and highlight the efficacy of repeated retrieval for different developmental ages and tasks.  相似文献

Deciding about people’s responsibility, intentions and need for punishment is particularly hard and it may be often associated with counterfactual thinking, which refers to the creation of mental alternatives to actual events. Ninety-three participants were asked to generate downward or upward counterfactuals regarding a given criminal event and, then, to give judgments about defendant’s predictability, responsibility, intentionality and punishment. Results showed that downward counterfactuals had led people to judge the event less intentional, the defendant less responsible and, therefore, to give him a less severe punishment (vice versa for upward). The relationship between counterfactuals and intentionality judgments was partially mediated by the perceived defendant’s predictability of the negative outcomes. Finally, downward counterfactuals were linked to a greater focus on the context (external factors), whereas upward counterfactuals on the defendant/victim’s behaviours (internal factors). Findings were discussed considering both theoretical decision-making models and applications on the judicial field.  相似文献

In this article I argue that Sartre’s notions of nothingness and “negatity” are not, as he presents it, primarily reactions to Hegel and Heidegger. Instead, they are a reaction to an ongoing struggle with Husserl’s notion of intentionality and related notions. I do this by comparing the criticism aimed at Husserl in Sartre’s Being and Nothingness to that presented in his earlier work, The Imagination, where he discusses Husserl more elaborately. Furthermore, I compare his criticism to Husserl’s own criticism of the “doctrine of immanent objects”, in order to show that Sartre’s notion of nothingness is a continuation of Husserl’s criticism, and that he turns Husserl’s own arguments against himself.  相似文献

有意遗忘是关于记忆研究的另一种实验范式,对于在实验中出现的要求遗忘的学习项目的记忆成绩差于要求记忆的项目的结果,目前主人存在着两种理论解释:基于编码的理论和基于提取抑制的理论。该实验运用单字提示方式,采用控制较为严密的补笔测验方法和加入所谓的“无关项”,对有意遗忘的心理过程进行进一步的探讨,实验表明:在单了提示方式下,被试在进行有意遗忘的过程中,既对记忆项进行了有意的复述又对遗忘项产生了提取抑制。  相似文献

采用特征-联合范式的研究发现, 面孔再认阶段可记录到明显的联合效应和特征效应; 然而, 与再认同属情景记忆的另一任务(来源提取)条件的相应效应尚未报道, 背景信息一致性对联合面孔和特征面孔提取的调节作用以及面孔不同特征对特征效应的影响也未考察。为澄清上述问题, 本文采用特征-联合范式, 并以位置为背景展开研究。实验含一个学习任务和两个测验任务(再认和来源提取)。结果显示, 再认和来源提取阶段均记录到显著的联合效应和特征效应, 且两类效应均在来源提取阶段更强; 任务类型与位置背景一致性交互影响提取绩效; 面孔外部特征和内部特征对特征效应的影响相似。表明联合效应和特征效应具有显著的任务类型敏感性, 这些效应是联合面孔和特征面孔的熟悉性较强且对源面孔的回忆加工相对较弱的结果, 且这两类面孔的提取为背景一致性所调节; 任务类型对两类效应的调节与双重加工理论模型相吻合。  相似文献

实验采用“学习-测验”范式, 考察在编码或提取中分别附加的干扰任务对内隐测验或外显测验中获得的ERP新旧效应产生的影响。结果表明, 在内隐测验中, 编码干扰对随后测验中的ERP新旧效应没有产生影响, 而提取干扰却改变了300~500ms新旧效应的脑区位置, 破坏了500~700ms新旧效应; 与之相反, 在外显测验中, 编码干扰破坏了500~700ms新旧效应, 而提取干扰对这一效应没有产生影响, 即编码与提取干扰对内隐或外显测验中的ERP新旧效应都产生了非对称性的影响, 但又存在着差异, 从而为两种记忆在编码与提取加工的关系上存在的分离现象提供了神经生理方面的证据。  相似文献

Current perspectives on the mechanism underlying the Subject Performed Task (SPT) effect have not yet reached a consensus. This study investigated whether the association between motor and verbal information is a key factor that explains the SPT effect. Experiment 1 and 2 tested whether motor and verbal retrieval memory performance were different when the association level was varied. Results showed that when subjects used low association learning materials, memory performance in either motor or verbal retrieval condition was significantly better than performance in the combined retrieval condition. Experiment 3 examined whether the level of association between motor and verbal information affects the SPT effect. Results revealed that the SPT effect disappeared when low association learning materials were used. Our findings imply that the high association level between motor and verbal information enables mutual activation of the two information types, leading to improved memory performance.  相似文献

The medial temporal lobe has been implicated in studies of episodic memory tasks involving spatio-temporal context and object-location conjunctions. We have previously demonstrated that an increased level of practice in a free-recall task parallels a decrease in the functional activity of several brain regions, including the medial temporal lobe, the prefrontal, the anterior cingulate, the anterior insular, and the posterior parietal cortices, that in concert demonstrate a move from elaborate controlled processing towards a higher degree of automaticity. Here we report data from two experiments that extend these initial observations. We used a similar experimental approach but probed for effects of retrieval paradigms and stimulus material. In the first experiment we investigated practice related changes during recognition of object-location conjunctions and in the second during free-recall of pseudo-words. Learning in a neural network is a dynamic consequence of information processing and network plasticity. The present and previous PET results indicate that practice can induce a learning related functional restructuring of information processing. Different adaptive processes likely subserve the functional re-organisation observed. These may in part be related to different demands for attentional and working memory processing. It appears that the role(s) of the prefrontal cortex and the medial temporal lobe in memory retrieval are complex, perhaps reflecting several different interacting processes or cognitive components. We suggest that an integrative interactive perspective on the role of the prefrontal and medial temporal lobe is necessary for an understanding of the processing significance of these regions in learning and memory. It appears necessary to develop elaborated and explicit computational models for prefrontal and medial temporal functions in order to derive detailed empirical predictions, and in combination with an efficient use and development of functional neuroimaging approaches, to further the understanding of the processing significance of these regions in memory.  相似文献

This article addresses theoretical and methodological problems in the study of aggression in infants and toddlers. It is argued that the occurrence of aggressive behavior in very young children must be considered against the background of their developing social competence. As a result, evidence for the infants' capacities to act with specific intentions and the infants' knowledge of the other as a distinctive individual having his own plans and goals are reviewed. Studies of early social interactions in humans are then examined with special emphasis on cognitive development and social cognition. Finally, the problem of dominance in very young children's groups is considered.  相似文献

测验效应指提取比同等时间的重复学习,在随后的记忆测验中有更好的成绩。多数理论从提取角度解释该现象。近些年,精细提取理论得到诸多研究支持,但2014年,Karpicke等人提出的情景背景理论,对测验激活语义关联信息的解释提出质疑,认为被试在提取模式中对先前时间背景信息的复原是测验效应形成的关键。本文比较了测验效应研究的最新理论,结合提取加工的研究方法和成果,从提取模式、提取方向的角度解释了测验效应的内在机制。  相似文献
