This paper uses the Process Dissociation Procedure to explore whether people can acquire unconscious knowledge in the serial reaction time task [Destrebecqz, A., & Cleeremans, A. (2001). Can sequence learning be implicit? New evidence with the Process Dissociation Procedure. Psychonomic Bulletin &Review, 8, 343-350; Wilkinson, L., & Shanks, D. R. (2004). Intentional control and implicit sequence learning. Journal of Experimental Psychology: Learning, Memory, and Cognition, 30, 354-369]. Experiment 1 showed that people generated legal sequences above baseline levels under exclusion instructions. Reward moved exclusion performance towards baseline, indicating that the extent of motivation in the test phase influenced the expression of unconscious knowledge. Experiments 2 and 3 revealed that even with reward, adding noise to the sequences or shortening training led to above-baseline exclusion performance, suggesting that task difficulty and the amount of training also affected the expression of unconscious knowledge. The results help resolve some current debates about the role of conscious awareness in sequence learning. 相似文献

Treadmill exercise enhances passive avoidance learning in rats: the role of down-regulated serotonin system in the limbic system 总被引:1,自引:0,他引:1
Chen HI Lin LC Yu L Liu YF Kuo YM Huang AM Chuang JI Wu FS Liao PC Jen CJ 《Neurobiology of learning and memory》2008,89(4):489-496
While serotonin (5-HT) may impair learning and memory, exercise has been reported to improve them. Whether chronic exercise can facilitate fear memory via regulating the serotonin system is unknown. We examined the effects of 4-week treadmill exercise training on levels of 5-HT and its metabolite 5-hydroxyindoleacetic acid (5-HIAA), the protein expression of its receptor 5-HT1A and transporter in the amygdala, hippocampus and prefrontal cortex of male Sprague–Dawley rats. Our results demonstrated that treadmill exercise (1) improved the passive avoidance learning performance; (2) decreased the 5-HT level in the hippocampus; (3) decreased the expression of 5-HT1A receptor in the amygdala without altering the transporter expression. Moreover, pretreatment with 0.1 mg/kg 8-hydroxy-di-n-propylamino tetralin, a selective 5-HT1A receptor agonist, impaired the passive avoidance performance and completely abolished the exercise-enhanced fear memory. Our results suggest that down-regulation of the 5-HT system in the limbic system, i.e., the reduction of the hippocampus 5-HT content and the amygdala 5-HT1A receptor expression, may be involved in the exercise-enhanced fear memory. 相似文献

The contingent-orienting hypothesis states that attentional capture by a task-irrelevant stimulus is contingent on whether that stimulus shares a feature property that is critical to the task at hand [Folk, C. L., Remington, R. W., & Johnston, J. C. (1992). Involuntary covert orienting is contingent on attentional control settings. Journal of Experimental Psychology: Human Perception and Performance, 18, 1030-1044]. Studies supporting this hypothesis have mostly used set size four displays throughout the experiment and thus constrict its ecological validity, since conclusions drawn from experiments using fixed set-size displays may not be generalized to other conditions with different set sizes. We used a spatial cueing paradigm in which a non-informative onset or color cue preceded an onset or a color target, and manipulated set size as a within- or between-subject factor. In four experiments, the original finding of Folk et al. (1992) was replicated only when a fixed set size (four) was used throughout. When both set-size four and eight were used in an experiment, stimulus-driven capture by onset in search of a color target was found even for set-size four displays. These results raise doubts as to the generality of the contingent-orienting hypothesis and help to delineate the boundary conditions on this hypothesis. 相似文献

Goldberg (Goldberg, L. R. (1999). A broad-bandwidth, public-domain, personality inventory measuring the lower-level facets of several five-factor models. In: I. Mervielde, I. Deary, F. De Fruyt, & F. Ostendorf (Eds.), Personality psychology in Europe (Vol. 7, pp. 7-28). Tilburg, The Netherlands: Tilburg University Press) has argued that the commercialization of personality measures limits the range of questions investigated in empirical research. We propose that the commercialization of interest measures has had a similar effect on research in vocational psychology. Following Goldberg’s example of developing public-domain personality markers, we also propose that the development of public-domain interest markers would facilitate new directions in career-related research. The present study outlines the development and validation of a set of public-domain Basic Interest Markers (BIMs) that are freely available on a website. Using Day and Rounds’ (Day, Susan. X, & Rounds, J. (1997). A little more than kin, and less than kind: Basic interests in vocational research and career counseling. Career Development Quarterly, 45, 207-220) basic interest taxonomy, 343 items and 31 BIM scales were generated. Validity evidence is presented from correlations with the General Occupational Themes and Basic Interest Scales of the Strong Interest Inventory (Harmon, L. W., Hansen, J. C., Borgen, F. H., & Hammer, A. L. (1994). Strong Interest Inventory applications and technical guide. Stanford, CA: Stanford University Press). Discriminant validity is demonstrated by the capacity for the BIMs to differentiate major field of education or training. Implications for research and use in applied settings are discussed. 相似文献

中学力学问题表征体系的动态特征 总被引:3,自引:0,他引:3
基于McDenott和Larkin的基本假设,该文提出了力学问题的表征体系,并用口语报告分析法实证研究了力学问题表征体系的动态特征。结果表明:问题解决者在解决力学问题过程中一般将建立4个不同层次的表征,并且在物理和数学表征层次所占时间显著多于在文字和朴素表征层次的时间。 相似文献

以初中一至三年级学生为对象,采用自尊量表(SES)和帮助行为调查问卷进行测查,以探讨自尊、受助者特征对其亲社会行为的影响。结果表明:(1)在社会道德认知和自我意愿层面上,大多数初中生能表现出积极的亲社会性助人趋向,部分学生的行为决策判定具有不一致性;(2)初中生的自尊程度不影响对他人需要的注意、归因以及行为方式的选择,但与帮助行为的价值取向、行为意愿等认知、情感因素有关,能直接影响自主性的亲社会行为;(3)初中生有关潜在受益者特征的某种认知结果及其相应的情感体验,对帮助型亲社会行为趋向有重要影响;(4)初中生的自尊及其所知觉的潜在量益者特征在亲社会行为趋向中交互作用不显著。 相似文献

自我控制是欺骗识别中一种重要的动机线索。但无论是在识别欺骗中, 自我控制扮演的动机线索角色, 还是在欺骗行为中, 自我控制扮演的监管机制的角色, 其认知机制和神经基础还不完全清楚。自我控制能力与自我控制资源对欺骗的影响也是不一样的, 而这些影响的神经基础也还没有完全破解。因此, 有必要结合行为、事件相关电位(ERP)及功能性磁共振(fMRI)等多种技术手段来考察识别欺骗和欺骗行为中自我控制能力和自我控制资源在欺骗中的作用及其心理机制。旨在探求在识别欺骗中是识别他人自我控制能力, 还是识别他人自我控制资源在起主要作用; 欺骗行为中是自我控制能力, 还是自我控制资源在起主要作用; 自我控制资源对欺骗行为的影响是符合能量耗竭观, 还是符合能量保存观。 相似文献

因果力比较范式下对效力PC理论的检验 总被引:3,自引:2,他引:1
在用图形方式集中呈现信息的条件下,用因果力大小比较的实验范式检验效力PC理论。233名大学生被试对不同化学药物影响动物基因变异的能力做大小比较判断。结果发现,对单一因果关系因果力大小的比较判断具有以下3个特点:(1)不对称性:在预防原因条件下的因果力判断一般符合效力PC理论,而在产生原因条件下的因果力判断一般不符合效力PC理论;(2)在同时变化协变值DP和结果基率P(E|~C)的产生原因条件下,多数被试使用DP规则。这与概率对比模型的预测相一致,而不支持效力PC理论;(3)在固定协变值DP而只变化结果基率P(E|~C)的产生原因条件下,多数被试使用变异比RP规则。这是目前所有的因果推理理论都不能解释的现象。 相似文献
