【摘要】 本研究采用学习-测试二阶段实验范式探讨了因果关系对类别特征推理任务及典型性判断任务的影响。被试被随机分配到因果关系组及控制组,因果关系组被试学习的类别的各典型特征间具有因果关系,而控制组被试学习的类别的各典型特征间无因果关系。研究结果表明,因果关系确实会影响类别特征推理任务及典型性判断任务。因果关系之所以会影响这两类任务,根本原因在于因果关系的存在导致处于类别因果关系结构中不同位置的特征维度具有的地位不同。更多还原

【Abstract】 The present study explored the effects of causal relations on category feature inference and typicality judgement using the study-test two-phase paradigm.The subject’s were randomly assigned to the casual relation group and the control group;and the causal relation group was to learn causal relations between typical features of the category while the control group was to learn no causal relations.The results suggested that causal relations did influence category feature inference and typicality judgement,the essential reason for which was that the presence of causal relations resulted in the different status of feature dimensions located in different positions in the causal structure of category.更多还原
