本研究采用2X2两因素(自变量分别为“心理模型数量”和不同“内容性质”)重复测量拉丁方实验方法,在范畴三段论推理题的内在结构为“形式正确”,且“推理者已经掌握相应的形式逻辑推理规则”的前提条件下,对西方学者提出的“心理模型”与中国学者提出的“推理题和推理者的推理知识双重结构模型”这两种理论模型再次进行了实验比较研究。结果表明,对于“正确形式—正确内容”和“正确形式—错误内容”两种不同结构的推理题,若按照形式逻辑规则来判定推理者“对各推理题的结论能否从两个前提中推论出来的推论结果”是否正确,则有:(1)当推理题含有错误内容的情况下,即使该推理题只是由“一个心理模型”所构成,也会使推理者降低对其结论判定为“正确”的可能性;(2)当推理题是由正确内容所构成时,即使该推理题是由三个心理模型所构成,对其结论判定为“正确”的可能性也要比“单模型——错误内容”构成的推理题的可能性更高。由此得到的比较结论是:在本实验条件下,“推理题和推理者的推理知识双重结构模型”对实验结果所做的解释要比“心理模型”理论所做的解释更为贴切。 相似文献

Whether valence change during evaluative conditioning is mediated by a link between the conditional stimulus (CS) and the unconditional stimulus (US; S-S learning) or between the CS and the unconditional response (S-R learning) is a matter of continued debate. Changing the valence of the US after conditioning, known as US revaluation, can be used to dissociate these accounts. Changes in CS valence after US revaluation provide evidence for S-S learning but if CS valence does not change, evidence for S-R learning is found. Support for S-S learning has been provided by most past revaluation studies, but typically the CS and US have been from the same stimulus category, the task instructions have suggested that judgements of the CS should be based on the US, and USs have been mildly valenced stimuli. These factors may bias the results in favour of S-S learning. We examined whether S-R learning would be evident when CSs and USs were taken from different categories, the task instructions were removed, and more salient USs were used. US revaluation was found to influence explicit US evaluations and explicit and implicit CS evaluations, supporting an S-S learning account and suggesting that past results are stable across procedural changes. 相似文献

Many of our cognitive capacities are shaped by enculturation. Enculturation is the acquisition of cognitive practices such as symbol-based mathematical practices, reading, and writing during ontogeny. Enculturation is associated with significant changes to the organization and connectivity of the brain and to the functional profiles of embodied actions and motor programs. Furthermore, it relies on scaffolded cultural learning in the cognitive niche. The purpose of this paper is to explore the components of symbol-based mathematical practices. Phylogenetically, these practices are the result of concerted organism-niche interactions that have led from approximate number estimations to the emergence of discrete, symbol-based mathematical operations. Ontogenetically, symbol-based mathematical practices are associated with plastic changes to neural circuitry, action schemata, and motor programs. It will be suggested that these practices rely on previously acquired capacities such as subitizing and counting. With these considerations in place, I will argue that computations, understood in the sense of Turing (1936), are a specific kind of symbol-based mathematical practices that can be realized by human organisms, machines, or by hybrid organism-machine systems. In sum, this paper suggests a new way to think about mathematical cognition and computation. 相似文献

摘要:群体共情是指群体成员内化和间接体验另一群体成员的认知和情绪情感的过程。群体共情与个体共情不同,表现在身份感、共情偏好和文化影响的差异等方面。群体共情对群际关系具有促进作用,有助于减少群际冲突,促进群际亲社会行为。共情动机和文化框架转换是分析群体共情对群际关系促进机制的两个视角。未来研究可以探索群体共情与个体共情神经机制的差异,建立群体共情对群际关系影响的综合模型,探索群体共情在群际关系改善中的作用机制。 相似文献

There is limited understanding of the relation between insomnia and aspects of eating among college students though available data suggest salient clinical relationships. The present study explored a potential transdiagnostic mechanism in the relation between insomnia symptoms and eating expectancies. Participants were a racially/ethnically diverse sample of 1589 college students (80.4% females; Mage = 22.2 years, SD = 5.27) from an urban university. Primary analysis included three regression-based models of eating expectancies. Insomnia symptoms served as the predictor, and emotion dysregulation served as the indirect (mediator) variable in all models. Results indicated that insomnia symptoms yielded a significant indirect effect through emotion dysregulation on expectancies of eating to help manage negative affect, alleviate boredom, and lead to feeling out of control. Students experiencing insomnia symptoms may be at higher risk for experiencing dysregulated emotions and consequently maladaptive eating expectancies compared to good sleepers. 相似文献
