FOK与情节记忆、语义记忆和内隐记忆关系的研究   总被引:3,自引:0,他引:3  
刘耀中 《心理科学》2001,24(2):184-187
实验采用R/K判断和PDP测量技术,研究了FOK判断与情节记忆、语义记忆和内隐记忆关系及其监测强度.实验结果表明FOK判断的准确性程度为R判断>K判断,即对情节记忆监测的准确性要大于对语义记忆监测的准确性.FOK对于自动加工的预测准确性差异不显著,说明FOK监测对内隐记忆的作用是微弱的,由此推测无记忆是意识最高层面的活动.对记忆监测水平强度是由意识--无意识逐渐减弱的.FOK判断对意识性水平较高的记忆活动监测的准确性较强.  相似文献

This study examined the association between support/interference from the best friend and closest parent to women's (a) satisfaction with the parent–daughter relationship, (b) satisfaction with the friendship, and (c) love for the romantic partner. The respondents (n = 162 females; 84% Caucasian, 1% Asian American, 10% Hispanic, 4% African American, and 1% Multiracial) completed a questionnaire packet to assess each of the factors. Results revealed that romantic love was unrelated to friend support, friend interference, or parental interference, but positively related to parental support. Parent support was a significant correlate of parent satisfaction, and a similar pattern emerged between friend support/friendship satisfaction. Further, best friend support moderated the relationship between friend interference and friendship satisfaction, such that interference was negatively related to satisfaction in low support conditions. Overall, the results suggested that network reactions to romance played a limited role in romantic affection, but were more strongly associated with network satisfaction.  相似文献

通过2个实验, 考察了语义类标记在中国手语词汇识别和语义提取中的作用。实验1采用手语词汇判断任务, 比较了有、无语义类标记的手语词汇识别。实验2采用语义决定任务, 探讨了语义类标记对手语词语义提取的影响。结果表明, 语义类标记影响聋生对手语词的识别和语义提取。聋生识别有语义类标记的手语词显著快于识别无语义类标记的手语词。当语义类标记与手语词的语义一致时, 能够促进聋生对手语词的语义提取; 当语义类标记与手语词的语义不一致, 会干扰聋生对手语词的语义提取。中国手语词语义类标记效应的发现, 丰富了中国手语词词汇认知的理论, 对聋人的语言教学和概念教学具有重要的启示。  相似文献

一种混合型前瞻记忆的加工机制   总被引:1,自引:0,他引:1       下载免费PDF全文

通过两个实验, 对以往研究忽略的一种基于事件进行反应、且具有时间线索的混合型前瞻记忆的加工过程进行考察。结果表明, 这种混合型的前瞻记忆可以通过控制加工或自动加工提取, 还可能两种加工交替存在, 被试在执行过程中, 根据时间信息, 有选择地、动态地将注意资源投入于不同时间段, 现有理论不能解释这种现象。对多重加工理论进行补充, 使之能够解释这种混合型前瞻记忆的加工机制。  相似文献

作者用以大学生为被试的实验考察, 基本条件句语义关系表达形式(充分关系、必要关系和析取关系表达形式)和作为心理模型外显建构的可能性判断任务对条件推理的可能影响。实验结果发现, 条件推理的语义关系表达形式效应显著, 条件句语义关系表达形式对被试条件推理有显著的影响, 条件推理成绩随条件句语义关系表达的外显程度增加而增加; 被试在可能性判断任务中对条件句所含心理模型的外显建构并没有明显改善条件推理的成绩; 在有可能性判断任务条件下, 被试外显心理模型建构的成绩变化模式并不能一致地预测条件推理成绩的变化模式。这些结果说明, 人们的条件推理可能并不是完全基于心理模型建构, 而是还受对条件句前后件之间语义关系理解的影响; 条件句表达形式中语义关系的外显内隐模式影响对条件句语义关系的知觉理解难易, 从而影响相应条件推理的成绩。  相似文献

为了探讨内隐记忆提取干扰效应是否敏于注意资源的变化,该实验沿用前期经典的“学习-测验”范式,通过在提取阶段同时设置两种不同刺激类型的干扰任务:箭头干扰和汉字干扰,以此来探讨内隐记忆提取干扰效应的本质所在。结果发现,不同提取干扰条件对内隐记忆产生不同程度的影响,汉字干扰对内隐记忆的影响比箭头产生的干扰更大。结果表明,干扰刺激类型会调节内隐记忆提取干扰效应的大小,证实内隐记忆提取干扰敏于注意资源的变化。  相似文献

Recent research indicates that individuals with nonthalamic subcortical (NS) lesions can experience difficulties processing lexical ambiguities in a variety of contexts. This study examined how prior processing of a lexical ambiguity influences subsequent meaning activation in 10 individuals with NS lesions and 10 matched healthy controls. Subjects made speeded lexical decisions on related or unrelated targets following homophone primes. Homophones were repeated with different targets biasing the same or different meanings on the second presentation. The effects of prime-target relatedness, interstimulus interval (200 or 1250 ms), and same vs. different meaning repetition were examined. Both the patient and control groups showed priming when the same homophone meaning was biased on repetition. When a different meaning was biased on the second presentation, no priming was evident in the controls, while facilitation remained present for the NS group, consistent with aberrant meaning selection and deactivation processes. These findings are discussed in terms of age and task-related repetition effects and current conceptions of frontal–subcortical involvement in cognition.David Copland is supported by the Australian Research Council  相似文献

An abnormal facilitation of the spreading activation within semantic networks is thought to under-lie schizophrenics' remote associations and referential ideas. In normal subjects, elevated magical ideation (MI) has also been associated with a style of thinking similar to that of schizotypal subjects. We thus wondered whether normal subjects with a higher MI score would judge "loose associations" as being more closely related than do subjects with a lower MI score. In two experiments, we investigated whether judgments of the semantic distance between stimulus words varied as a function of MI. In the first experiment, random word pairs of two word classes, animals and fruits, were presented. Subjects had to judge the semantic distance between word pairs. In the second experiment, sets of three words were presented, consisting of a pair of indirectly related, or unrelated nouns plus a third noun. Subjects had to judge the semantic distance of the third noun to the word pair The results of both experiments showed that higher MI subjects considered unrelated words as more closely associated than did lower MI subjects. We conjecture that for normal subjects high on MI "loose associations" may not be loose after all. We also note that the tendency to link uncommon, nonobvious, percepts may not only be the basis of paranormal and paranoid ideas of reference, but also a prerequisite of creative thinking.  相似文献

工作记忆与复杂认知任务之间的关系已成为工作记忆研究领域的热点问题。大量研究表明,工作记忆广度不仅是评价工作记忆能力的一种指标,而且也是衡量一个人的高级认知能力的预报因子。本文从工作记忆的本质以及工作记忆与一般流体智力之问的关系人手,分析了干扰不仅是影响工作记忆容量个体差异的关键因素,而且也在工作记忆与一般流体智力的关系中起着重要的影响作用。  相似文献

The pervasive use of distributional semantic models or word embeddings for both cognitive modeling and practical application is because of their remarkable ability to represent the meanings of words. However, relatively little effort has been made to explore what types of information are encoded in distributional word vectors. Knowing the internal knowledge embedded in word vectors is important for cognitive modeling using distributional semantic models. Therefore, in this paper, we attempt to identify the knowledge encoded in word vectors by conducting a computational experiment using Binder et al.'s (2016) featural conceptual representations based on neurobiologically motivated attributes. In an experiment, these conceptual vectors are predicted from text-based word vectors using a neural network and linear transformation, and prediction performance is compared among various types of information. The analysis demonstrates that abstract information is generally predicted more accurately by word vectors than perceptual and spatiotemporal information, and specifically, the prediction accuracy of cognitive and social information is higher. Emotional information is also found to be successfully predicted for abstract words. These results indicate that language can be a major source of knowledge about abstract attributes, and they support the recent view that emphasizes the importance of language for abstract concepts. Furthermore, we show that word vectors can capture some types of perceptual and spatiotemporal information about concrete concepts and some relevant word categories. This suggests that language statistics can encode more perceptual knowledge than often expected.  相似文献
