关于错误记忆成因的解释主要有三种理论:建构主义理论、来源监控理论、模糊痕迹理论。建构主义理论认为对经验的记忆和对其解释的混合导致错误记忆产生;来源监控理论主张记忆来源的混淆或错误归因导致错误记忆发生;模糊痕迹理论断言当需要精确记忆却提取主旨记忆时或提取错误精确记忆时就会产生错误记忆。 相似文献

即便在相同的情形中, 每个人所做的决策也有千差万别, 导致决策个体差异的因素之一就是数学能力。文章综述了算术能力、数量表征、概率推理能力以及数学认知启发式对各种决策的影响。目前这方面的研究或者采用相关范式将数学能力作为决策的外部关联因素, 或者采用成分范式确定决策过程所需要的特定数学认知成分; 观点上的主要争论在于是一般认知能力还是数学能力在预测决策表现, 以及数学能力是否总是对决策有积极作用; 此外, 双系统模型和模糊痕迹理论有望为决策的个体差异提供理论解释。今后研究应该澄清上述争论, 确定合适的研究范式和结果解释框架, 并探讨更多提高决策能力的措施。 相似文献

个体决策后的反馈对随后的结果监控和行为调整起着至关重要的作用。事件相关脑电位研究发现, 反馈负波(feedback-related negativity, FRN)是与决策后反馈加工过程紧密相关的脑电成分。近10年来关于FRN的理论解释, 在最初经典的强化学习理论和情绪动机假说的基础上又提出了反应-结果的预测模型、奖赏正波理论以及积极情绪启动模型。未来的研究应该立足于大样本, 采用互补的研究手段和多样的分析技术来探讨FRN的心理意义; 同时考虑将FRN作为奖赏加工的脑电指标, 研究社会互动情境下的人类行为。 相似文献

在近期出版的Medical Decision Making上,Valerie V.Reyna博士对医学决策和健康决策中的模糊痕迹理论(fuzzy trace theory)做了综述性的介绍。模糊痕迹理论是Reyna等于1991年提出的认知心理学理论,其核心是信息的要点表述(gist rep-resentation)和细节表述(verbatim representation)对于认知有不同影响。 相似文献

The characteristics of mediational mechanisms based upon magnitude of reinforcement were investigated using rats. In two experiments, two-choice discriminations were trained in which selections of one lever in one external stimulus and a second lever in another external stimulus were reinforced with food. In the first experiment, it was found that the discrimination was acquired more rapidly when one choice was reinforced with a large number of food pellets and the other with a smaller number of pellets than when other configurations of reinforcement magnitude were provided. In the second experiment, reversal of a two-choice discrimination was found to be facilitated by prior exposure of the animals to the reversed relationships between the external stimuli and magnitudes of reinforcement. These results were consistent with predictions from a stimulus or associative view of anticipatory processes based upon magnitude of reinforcement. 相似文献

We describe the development, preliminary psychometric properties, and cross-validation of the Behavioral Evaluation of Disorders of Sleep (BEDS: Schreck 1997/1998). Parental reports of problem sleep behavior in elementary school aged children 5 years to 12 years were collected for two samples. With the first sample, an exploratory factor analysis of parental responses (N = 307) resulted in reports of five distinct types of sleep problems: Expressive Sleep Disturbances; Sensitivity to the Environment; Disoriented Awakening; Sleep Facilitators; and Apnea/Bruxism. Four of these factors (Expressive Sleep Disturbances; Sensitivity to the Environment; Disoriented Awakening; and Apnea) were confirmed with the new participant sample (N = 1054). These factors of problem sleep behavior were similar to findings in other studies, with the exception of the exclusion of bedtime behavior problems. 相似文献

施动感是个体在自主运动过程中对自身行为产生的主体性体验,揭示其发展过程对了解自我意识的形成具有重要意义。三阶段模式全面概括了施动感的发展过程。婴儿形成动作预测、建立动作-效果联结以及与养育者良好的人际互动对施动感的发展起着重要作用。未来施动感发展研究应从多种施动感生成理论出发,改进婴幼儿施动感的测量范式,探索施动感发展与社会认知发展、自闭症症状的关联。 相似文献

We study the structure of algebraic -closed subsets of an algebraic lattice L, where is some Browerian binary relation on L, in the special case when the lattice of such subsets is an atomistic lattice. This gives an approach to investigate the atomistic lattices of congruence-Noetherian quasivarieties.V. A.

Intolerance of Uncertainty (IU ) is a transdiagnostic vulnerability factor involved in depression and anxiety symptoms and disorders. IU encompasses Prospective IU (“Unforeseen events upset me greatly”) and Inhibitory IU (“The smallest doubt can stop me from acting”). Research has yet to explore whether subgroups or classes of people exist characterized by different profiles of IU . This study used latent class analysis to identify such subgroups and examined if different classes of IU were distinct in terms of several cognitive vulnerabilities and psychological symptoms. Data were obtained from 519 students completing a 12‐item measure of IU . Four subgroups were identified, characterized by low IU , predominantly Prospective IU , predominantly Inhibitory IU , and high IU , respectively. People in the high IU class reported cognitive vulnerabilities and depression and anxiety more than people in the low IU class. Inhibitory IU was more strongly associated with poor outcomes than was Prospective IU . 相似文献

In many cases, the formation of intermediate phases in solid-state reaction starts from nucleation, proceeds at first by lateral spreading along interface in the form of narrow layer and after that continues slow growth in normal direction. So far, the lateral growth stage was considered as something almost instant. Yet, if the emerging phase is not the first one and the already growing phase layer has high diffusivity, the lateral growth can be also kinetically suppressed due to ‘sucking out’ of atoms from the moving interface into the growing first phase layer. Criteria of such suppression are formulated and examples of real systems are discussed. 相似文献
