序列学习中的内隐学习效应 总被引:2,自引:0,他引:2
该研究采用较为复杂的包含图形出现的位置规则和顺序规则的实验材料,通过对比被试直接测验和间接测验、内隐学习和外显学习成绩的异同,考察了序列学习中的内隐学习效应,并探讨了规则特点对内隐学习效应的影响。结果表明,在图形位置的序列学习中存在内隐学习效应,内隐学习效应的大小受规则特点的影响。 相似文献

The French molecular biologist François Jacob outlined a theory of evolution as tinkering. From a methodological point of view, his approach can be seen as a biologic specification of the relation between laws, describing coherently the dynamics of a system, and contingent boundary conditions on this dynamics. From a semiotic perspective, tinkering is a pragmatic concept well-known from the information-theoretic anthropology of Claude Lévi-Strauss. In idealized contrast to an engineer, the tinkerer has to accept the concrete restrictions on his material resources as only gradually changeable constraints on his projects. Jacobian biopragmatics examines evolution as a biologic analogue to human tinkering devoid of any projecting subjectivity. To validate this analogy, four basic principles concerning main formal aspects of evolutionary objects, agents, histories, and consistency criteria are proposed.This revised version was published online in October 2005 with corrections to the Cover Date. 相似文献

This paper introduces a technique for measuring the degree of (in)coherence of inconsistent sets of propositional formulas. The coherence of these sets of formulas is calculated using the minimal models of those sets in G. Priest's Logic of Paradox. The compatibility of the information expressed by a set of formulas with the background or domain knowledge can also be measured with this technique. In this way, Hunter's objections to many-valued paraconsistent logics as instruments for measuring (in)coherence are addressed. 相似文献

The relationship between self‐regulatory capacities and self‐esteem as well as well‐being is examined by a mediation model that views self‐regulation as promoting the development of identity achievement which, in turn, is expected to be associated with well‐being. Among secondary school students (Study 1) identity achievement mediated the association between the self‐regulatory capacity of attention control and self‐esteem. In Study 2 (university students), the mediational effect of identity achievement was found for the relationship between the self‐regulatory capacity of action control and well‐being. Explicit motives moderated this association. In sum, a firm identity enhances well‐being by lending a sense of continuity to one's life. However, explicit motives have a substitution effect by giving direction to life when lacking firm identity commitments. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

This study examines the crime patterns of 76 New Zealand serial sexual offenders in order to determine the extent to which offenders display locational consistency in their choice of crime locations. More specifically, the hypothesis was that there would be intraseries consistency in the distances travelled (spatial consistency) and the characteristics of the crime sites selected (environmental consistency) by serial sexual offenders. For spatial consistency to be tested, the distances travelled from home to offend and the criminal range for each offence series were analysed. Support was found for spatial consistency, and, in line with much overseas research, it was also found that the offenders typically did not travel very far from home to offend (median distance of 3 km). The environmental consistency measure was made up of various physical, temporal, and contextual variables that described the environmental characteristics of an offence. As hypothesised, it was found that offenders displayed intraseries environmental consistency in offence site selection beyond the level of that expected by chance. The implications of this both for understanding offender spatial decision making and for geographical profiling are discussed. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

不同的情绪在内隐态度与外显态度表现过程中塑造着不同的心理环境, 调节内隐态度和外显态度的一致性。正性情绪增加了内隐态度与外显态度的联结, 然而负性情绪对内隐态度与外显态度联结的调节作用表现并不一致。单一考虑情绪的正负效价不足以解释具体情绪影响的差异性, 情绪的确定性、情绪与直觉信任的交互作用均会对内隐态度与外显态度的联结产生影响。理论方面, 联结性-推理性评价模型及情绪-信息模型对情绪调节内隐态度与外显态度联结的内在机制进行了解释。未来研究可进一步探索特定情绪对内隐态度与外显态度联结的调节作用, 并考察情绪是否会对内隐刻板印象与外显刻板印象的联结产生调节作用, 以及采用认知神经科学技术揭示情绪调节内隐态度与外显态度联结的神经机制。 相似文献

记忆包括编码和提取两个重要阶段, 以往研究多关注内隐和外显记忆在提取阶段的脑机制分离, 那二者在编码阶段的脑机制是否不同?为探讨这个问题, 该实验采用两阶段的迫选再认方式, 把学习项目区分成三类:随后被选择且告知为见过的项目(记住), 随后被选择但告知为猜测的项目 (启动)以及随后未被选择的项目(忘记)。结果表明, 从200 ms开始的颞区负走向Dm效应为内隐记忆(启动vs忘记)所特有, 反映了对刺激的知觉加工过程, 400~500 ms前额区正走向的Dm效应为外显记忆(记住vs忘记)所特有, 反映了对刺激的精细加工过程, 而200~300 ms中央区及600 ms开始的顶区负走向的Dm效应为两种记忆类型所共有, 它们分别反映了对刺激的注意状态以及把编码后的刺激信息登记进相应记忆系统的过程。因此, 内隐记忆与外显记忆在编码阶段的脑机制既存在着分离, 也存在着重叠的现象。 相似文献

We compare two different styles of Higher-Order Unification (HOU): the classical HOU algorithm of Huet for the simply typed λ-calculus and HOU based on the λσ-calculus of explicit substitutions. For doing so, first, the original Huet algorithm for the simply typed λ-calculus with names is adapted to the language of the λ-calculus in de Bruijn's notation, since this is the notation used by the λσ-calculus. Afterwards, we introduce a new structural notation called unification tree, which eases the presentation of the subgoals generated by Huet's algorithm and its behaviour. The unification tree notation will be important for the comparison between Huet's algorithm and unification in the λσ-calculus whose derivations are presented into a structure called derivation tree. We prove that there exists an important structural correspondence between Huet's HOU and the λσ-HOU method: for each (sub-)problem in the unification tree there exists a counterpart in the derivation tree. This allows us to conclude that the λσ-HOU is a generalization of Huet's algorithm and that solutions computed by the latter are always computed by the former method. 相似文献
