摘要
分类及类别特征推理是类别知识的两大重要功能。研究表明,两种任务之间存在本质差异。因此,探讨类别特征推理的认知及神经机制对于拓展类别相关理论非常重要。已有研究发现,类别标签、典型性程度以及类别特征间的因果关系都会影响类别特征推理任务,而且,类别特征推理任务与分类任务的神经基础不同。未来研究方向应当关注类别标签以及类别特征间的因果关系分别与典型性程度之间的交互作用,在未来神经机制方面的进一步研究应当设计更符合自然情境下的特征推理任务范式。
Categorization and category-based feature inference are two important functions of category knowledge.Results from previous studies suggest that there are essential difference between categorization and category-based feature inference.Therefore,it was highly important to explore the cognitive and neural mechanisms of category-based feature inference for widening the theories relative to category.Previous studies have shown that category label,typicality level and causal relations between category features affect category-based feature inference tasks.Moreover,it has been found that the neural basis of category-based feature inference and categorization are different.Feature behavioral researches should focus on the interactions between category label and typical level as well as causal relations and typical level.In addition,feature researches on neural mechanisms should design the experiment paradigms in accordance with the tasks in natural situations.
