汉字内隐记忆的实验研究(Ⅱ):任务分离和反应倾向 总被引:9,自引:0,他引:9
在实验I的基础上,操纵学习时的呈现时间(250ms,500ms,750ms)和注意变量(目标和非目标字),运用任务分离方法及间接证明逻辑,比较了再认测验和整字偏好测验在不同条件下的辨别力(A′)和反应倾向(B″)。结果:(1)双向功能分离的出现表明再认测验和偏好测验存在本质差异。根据“过程纯净”假设,可以推证内隐记忆存在于偏好测验中。此时,匹配比较法的标准未满足。(2)偏好测验中,500ms呈现目标字时,有显著正向启动效应:750ms呈现非目标字时,有显著负向启动效应。(3)内隐记忆和外显记忆发生时,都具有稳定的心理状态。但是前者的报告标准较松宽,而后者的较严格。 相似文献

内隐记忆研究的实验方法探索:启动效应计量方法的改进思路及其实验研究 总被引:2,自引:0,他引:2
以实验鉴定了常规的启动效应计量方法的有效性程度,并为客观地计量启动效应,创用了“超意识广度法”、“二次比较法”等.结果发现:(1)如被试数量较少,以不同补笔率为“基线值”所求得的启动效应之间发生显著差异的可能性存在;(2)超意识广度法能克服“阈下呈现刺激法”“分散注意法”的不足,为内隐记忆提供有利的识记情境;(3)“二次比较法”能为正常人内隐记忆的存在提供更为直接、可靠的证据,并能客观、精确地计量启动效应。 相似文献

Repetition priming is a mnemonic phenomenon that has attracted considerable attention from neuropsychologists and cognitive scientists. In an attempt at elucidating the putative mechanisms of priming, the present review draws on evidence from both domains. The review is restricted to verbal priming of visually presented stimuli—an area that accounts for the majority of empirical studies of priming. A number of theoretical accounts are presented. The interim conclusion is that neither multiple systems nor unitary system-multiple process theories can adequately explain the data on priming, although both contain many valid components. An integrative model is proposed to improve the explanation of the empirical evidence. The central assertion of the proposed model is that repetition priming depends on perceptual processes that can be mapped on specific neural systems. It is postulated that individual differences in perceptual processing ability predict variability in memory performance. It is proposed that data-driven priming of verbal stimuli critically depends on the activity of primary and secondary visual cortices in the right hemisphere, whereas conceptually-driven priming is hypothesized to rely on the activities of higher order tertiary association cortices in language areas and more anterior neocortical areas. 相似文献

It is difficult to gain unambiguous evidence on the use of concepts by infants. Many results can be accounted for in terms of action-based strategies. The evidence reported here fulfils the minimal criteria for the operation of working concepts in infants. Search tasks are used with a filled interval which forces memory-search, and the object is hidden in containers which fulfil their customary job or violate it. Infants treat an upright cup as a more reliable location marker than an inverted one. A series of experiments probes the phenomenon. The results indicate that the infants have a working concept of containment which can be triggered by the provision of containers in their canonical orientation. Even “object permanence tasks” lead infants to access their knowledge of the relationships into which things typically enter in the world outside the laboratory. 相似文献

It is a common task to give children a picture containing implicit depth cues and to require them to extract depth information from it. The cues are always selected from the adult repertoire; little is known about children's production of their own cues. In this experiment, 5- to 10-year-old children were required to draw one object behind another in a situation in which adults invariably produce the further object partially occluded by the nearer. The results were an age-related decline in the tendency to segregate the objects and an increase in the tendency to group the objects using partial occlusion, with a cross-over at 8 years. At all ages some children drew one object inside the boundary of the other. It is argued that the results are composed of two tendencies, a gradual mastery of discrete scaling phenomena (e.g., “up” on the page means “further”) within a given style, and a set of decisions to be made between incompatible styles. 相似文献

The temporal characteristics of auditory memory were investigated using a reaction time paradigm. The study attempted to determine whether or not there are functionally distinct left and right hemisphere components of auditory memory with different capacities for the retention of nonlinguistic information, such as fundamental frequency, over the course of several seconds. The results indicated that fundamental frequency information in auditory memory remains substantially unchanged over the course of 2 sec. No evidence was found for the existence of separate left and right hemisphere components of auditory memory with different temporal characteristics. The implications of this finding for the organization of auditory memory in the brain are discussed. 相似文献

中小学师生的校园暴力内隐观研究 总被引:3,自引:0,他引:3
本研究用自编问卷对2386名中小学生和504名中小学教师进行了调查,结果表明,中小学师生普遍认可比较严重的身体攻击和性骚扰为校园暴力,不太认可言语攻击为校园暴力。学生的内隐观存在性别、城乡和年级差异,教师的内隐观基本不受性别、城乡、年级和学历影响。教师比学生更认可身体攻击为校园暴力,而学生比教师更认可言语攻击、财产破坏和一般性的体罚为校园暴力。 相似文献

Basic research on avoidance by Murray Sidman laid the foundation for advances in the classification, conceptualization and treatment of avoidance in psychological disorders. Contemporary avoidance research is explicitly translational and increasingly focused on how competing appetitive and aversive contingencies influence avoidance. In this laboratory investigation, we examined the effects of escalating social-evaluative threat and threat of social aggression on avoidance of social interactions. During social-defeat learning, 38 adults learned to associate 9 virtual peers with an increasing probability of receiving negative evaluations. Additionally, 1 virtual peer was associated with positive evaluations. Next, in an approach–avoidance task with social-evaluative threat, 1 peer associated with negative evaluations was presented alongside the peer associated with positive evaluations. Approaching peers produced a positive or a probabilistic negative evaluation, while avoiding peers prevented a negative evaluation (and forfeited a positive evaluation). In an approach–avoidance task with social aggression, virtual peers gave and took money away from participants. Escalating social-evaluative threat and aggression increased avoidance, ratings of feeling threatened and threat expectancy and decreased ratings of peer favorableness. These findings underscore the potential of coupling social defeat and approach–avoidance paradigms for translational research on the neurobehavioral mechanisms of social approach–avoidance decision-making and anxiety. 相似文献
