个体需要将亲身经历的核心事实信息及其发生的时间、空间等背景信息绑定起来形成情景记忆,绑定加工能力的发展是儿童情景记忆发展的基础。目前,儿童情景记忆绑定加工研究的主要范式有要素绑定范式和配对关联学习范式。绑定加工在儿童期的发展表现出项目-空间绑定记忆优于项目-时间绑定记忆,复杂任务的绑定加工水平较低的特点。儿童情景记忆绑定加工的发展依赖于编码和提取能力的发展、执行功能认知灵活性的提高以及内侧颞叶和前额叶皮层的发育。未来可以对情景记忆绑定加工的发展开展纵向研究、采用VR技术提高绑定加工研究的生态效度、加强对情景记忆绑定加工神经机制的探讨等。  相似文献

流畅性是个体做学习判断(Judgements of Learning, JOLs)时的重要线索,主要包括加工流畅性和提取流畅性。实验采用联想字对作为实验材料,把做JOLs的时间分为即刻JOLs (Immediate:I)(学习完一个项目立即判断),短时延迟JOLs(Delay condition: D1)和长时延迟JOLs(D2),考察不同JOLs时间条件下,流畅性线索对学习不良儿童和一般儿童的JOLs的不同预测模式。被试为普通小学五年级学习不良和一般儿童各20名,结果发现,一般儿童在I条件下主要利用加工流畅性,在D条件下主要利用提取流畅性做JOLs,而学习不良儿童无论在I还是D条件下均主要利用提取流畅性线索做JOLs。加工流畅性在I条件下效度较高,提取流畅性在D条件下效度较高  相似文献

摘 要 本研究将经典情绪启动范式和学习-再认范式相结合,探讨学习时启动与目标的情绪一致性对目标再认的影响。在记忆编码阶段,以情绪面孔图片为启动刺激、一般情绪图片为目标刺激,要求被试对目标图片的效价进行判断;在提取阶段向被试呈现一般情绪图片,要求被试判断是否在前一阶段见过。结果表明,编码阶段的加工背景对记忆提取产生了显著影响。一致启动促进了认知加工与记忆编码,提高了再认正确率。ERP结果也表明,在目标刺激呈现后300-500ms,编码时的情绪一致性对再认阶段消极目标诱发的ERP产生了显著影响。  相似文献

生存加工比控制条件有更好的记忆表现,产生稳定的记忆优势,这就是记忆生存优势.已有研究多采用行为学实验验证了此现象的存在,但没有确定该优势发生在记忆的何种阶段.本研究采用ERP技术和“间接学习-再认”实验范式,比较被试在生存情境、迁徙情境和愉悦判断中对词汇编码和提取过程的记忆加工,结果发现:在500-700ms时间段,生存情境的相继记忆效应显著大于迁徙情境和愉悦判断:在400-600ms时间段,生存情境的新旧效应显著大于迁徙情境和愉悦判断.表明生存加工具有编码和提取双重优势.  相似文献

配对词组的难度对策略使用效果的影响   总被引:3,自引:1,他引:2  
探讨人工合成配对词组的难度对精加工策略使用效果的影响。材料为26对根据其联想程度高低分为两组的配对名词组。各分为4组的一、三、五年级学生采用不同策略学习上述材料。研究结果表明:策略确实提高了被试的总体学习成绩;被试学习难度低的材料与难度高的材料相比,策略的促进效果更明显。该结果说明,材料难度极大地影响对策略的使用效果。  相似文献

协作抑制是指小组提取的信息量比等量个体单独提取的信息总量要少。对于协作过程降低小组成员提取潜能的机制解释,不同研究之间仍有争论。本研究实验1使用经典的生存加工范式,实验2使用联想记忆训练法,分别考察编码加工方式和编码相似性对协作提取成绩的影响,从而检验提取抑制和策略破坏机制是否能分别影响协作抑制。研究结果表明,被试在生存和非生存(愉悦度和自我经历)加工条件下都出现协作抑制现象,而生存加工条件下的协作抑制量显著小于非生存加工条件;在使用联想记忆训练法之后,相同学习顺序组没有出现协作抑制,而不同学习顺序组出现了经典的协作抑制。本研究结果为协作抑制的可能存在的多机制解释提供了证据。  相似文献

当人们与搭档组成社会群体一起协作讨论某些已经发生的事件或经验时, 该社会群体中的成员关系对协作提取成绩的影响仍不明确。本研究通过两项实验, 分别使用语词词单和情景故事作为实验材料, 考察成员关系(包括关系类型和关系时长)对协作提取成绩的影响。研究结果表明, 当记忆的材料为语词词单时, 青年陌生组出现了协作抑制; 而当记忆的材料为情景故事时, 青年夫妻和老年夫妻组均出现了协作促进。此外, 老年夫妻在协作提取情景故事的过程中使用的有效交流策略更多, 且这些有效交流策略的使用与更高的协作提取成绩有关。该结果支持了具有长时亲密关系的老年夫妻之间的“交互记忆系统”对协作促进的关键作用, 为理解成员关系对协作提取成绩的影响提供了全面的证据。  相似文献

提取练习效应指相比同等时间的重复学习,对所学材料进行提取练习(即使无反馈)可使被试在之后的回忆测验中表现更好。早期研究从编码或提取单维度地对提取练习效应进行了描述性解释,新近以来,研究者整合了编码和提取在提取练习效应中的作用,从记忆加工全过程的角度考察了提取练习效应的产生机制,并得到诸多研究证据的支持。论文梳理了提取练习效应产生机制的各类假说,并重点分析比较了精细提取假说和情景背景假说,指出后者在解释提取练习效应上的优势。未来研究可结合认知神经科学的研究技术为情景背景假说提供更直接的证据,有关提取练习对于短期和长期记忆促进效果的争议也有待进一步解释厘清,同时如何在揭示其原理的基础上将其更高效地加以应用亦有待实践探索。  相似文献

该研究采用ECM实验范式,操纵被试编码阶段加工方式,分析被试情绪状态与记忆成绩之间关系。情绪电影片段诱发被试高兴或悲伤情绪后,要求被试在学习情绪词时进行有意记忆或熟悉判断或结构判断,完成分心任务后进行自由回忆。结果发现:高兴组和悲伤组采用三种加工方式学习情绪词时均出现ECM;在高兴或悲伤状态下,被试进行结构判断学习情绪词时ECM效应量大,进行有意记忆和熟悉判断学习情绪词时ECM效应量小。  相似文献

本研究以93个学前儿童为研究对象,考察了配对联想学习能力和语音意识在汉字阅读和词汇发展中的作用及其相互关系,其中,配对联想学习分为假词、非词、符号三种形式。结果发现,语音意识是解释汉字阅读的最重要变量,配对联想学习能力对词汇发展具有独特贡献;不会阅读者在假词和非词学习中比初学阅读者差,而在非语言的符号学习中没有差异。  相似文献

The present study explored self-initiated object-location memory in ecological contexts, as aspect of memory that is largely absent from the research literature. Young and older adults memorized objects-location associations they selected themselves or object-location associations provided to them, and elaborated on the strategy they used when selecting the locations themselves. Retrieval took place 30 min and 1 month after encoding. The results showed an age-related decline in self-initiated and provided object-location memory. Older adults benefited from self-initiation more than young adults when tested after 30 min, while the benefit was equal when tested after 1 month. Furthermore, elaboration enhanced memory only in older adults, and only after 30 min. Both age groups used deep encoding strategies on the majority of the trials, but their percentage was lower in older adults. Overall, the study demonstrated the processes involved in self-initiated object-location memory, which is an essential part of everyday functioning.  相似文献

时间顺序信息作为记忆项目之间的重要联结要素之一, 易受到情绪的干扰。本研究通过3项实验探究编码方式与叙事连贯性是否以及如何调节情绪对于时间顺序记忆的干扰。实验1采用2 (编码方式:叙事编码/离散编码) × 3 (情绪类型:正性/负性/中性)的混合实验设计, 其中编码方式为被试间变量, 探究编码方式是否能调节图片材料中情绪信息对时间顺序记忆的干扰。结果显示, 在离散编码组, 负性情绪条件下的时间顺序记忆正确率显著比其他两种条件低; 相反, 在叙事编码组, 三种情绪类型下的时间顺序记忆没有显著差异。实验2采用两种情绪类型(中性和负性)的词语刺激, 检验编码方式对时间顺序记忆的影响是否跨材料具有普适性。实验3通过操纵项目之间的叙事连贯性程度, 进一步探究上述效应是否依赖于项目间连贯性程度。结果显示, 上述叙事编码效应仅在项目之间具有高连贯性时出现。本研究不仅发现了叙事编码对于情绪记忆中时间信息的保持机制, 还指明了叙事编码效应中连贯性程度的重要性。  相似文献

Working memory and episodic memory decline with age. However, as they are typically studied separately, it is largely unknown whether age-associated differences are similar. A task design was developed in which visual working memory and episodic memory performances were measured using the same stimuli, with both tasks involving context binding. A 2-back working memory task was followed by a surprise subsequent recognition memory task that assessed incidental encoding of object locations of the 2-back task. The study compared performance of younger (N=30; Mage=23.5, SDage=2.9, range=20-29) and older adults (N=29; Mage=72.1, SDage=6.8, range=62-90). Older adults performed worse than younger adults, without an interaction effect. In younger, but not in older adults, performance on the two tasks was related. We conclude that although age differences (Young>Older) are similar in the working memory and incidental associative memory tasks, the relationship between the two memory systems differs as a function of age group.  相似文献

Reconsolidation theory states that memories are labilized through reactivation, making them prone to change, before being re-consolidated. When information in memory requires updating, reconsolidation theory therefore predicts that reminders of previously learned information should facilitate updating of that information and should thus improve memory for the updated information. In two experiments, we tested this prediction by investigating memory for word pairs over a short time-scale. Participants studied word pairs (A–B), some of which were subsequently updated with word pairs that shared the first word (A–C). Half of the A–C pairs received a pre-study reminder of the first word in the pair so as to reactivate and labilize A–B memory. In a recognition memory test targeting the A–C list, reminders by and large had no effect on memory. Results thus failed to support the predictions of reconsolidation theory.  相似文献

Object-location memory (OLM) enables us to keep track of the locations of objects in our environment. The neurocognitive model of OLM (Postma, A., Kessels, R. P. C., & Van Asselen, M. (2004). The neuropsychology of object-location memory. In G. L. Allen (Ed.), Human spatial memory: Remembering where (pp. 143–160). Mahwah, NJ: Lawrence Erlbaum, Postma, A., Kessels, R. P. C., & Van Asselen, M. (2008). How the brain remembers and forgets where things are: The neurocognition of object-location memory. Neuroscience & Biobehavioral Reviews, 32, 1339–1345. doi:10.1016/j.neubiorev.2008.05.001) proposes that distinct brain regions are specialised for different subprocesses of OLM (object processing, location processing, and object-location binding; categorical and coordinate OLM; egocentric and allocentric OLM). It was based mainly on findings from lesion studies. However, recent episodic memory studies point to a contribution of additional or different brain regions to object and location processing within episodic OLM. To evaluate and update the neurocognitive model of OLM, we therefore conducted a systematic literature search for lesion as well as functional neuroimaging studies contrasting small-space episodic OLM with object memory or location memory. We identified 10 relevant lesion studies and 8 relevant functional neuroimaging studies. We could confirm some of the proposals of the neurocognitive model of OLM, but also differing hypotheses from episodic memory research, about which brain regions are involved in the different subprocesses of small-space episodic OLM. In addition, we were able to identify new brain regions as well as important research gaps.  相似文献

编码与提取是记忆的两个重要加工阶段, 虽然多数研究认为记忆的编码与提取过程是重叠的, 但也有一些研究结果证实了二者之间存在着差异性。这些研究主要从行为和神经成像两方面探讨编码与提取的非对称性关系, 并通过双加工模型及记忆两阶段神经生理学模型加以解释。综合以往研究, 编码与提取加工之间可能存在着多重复杂的关系。  相似文献

The ability to recognise past events along with the contexts in which they occurred is a hallmark of episodic memory, a critical capacity. Eye movements have been shown to track veridical memory for the associations between events and their contexts (relational binding). Such eye-movement effects emerge several seconds before, or in the absence of, explicit response, and are linked to the integrity and function of the hippocampus. Drawing from research from infancy through late childhood, and by comparing to investigations from typical adults, patient populations, and animal models, it seems increasingly clear that eye movements reflect item–item, item–temporal, and item–spatial associations in developmental populations. We analyse this line of work, identify missing pieces in the literature and outline future avenues of research, in order to help elucidate the development of episodic memory.  相似文献
