摘　　要：类概念是日常生活的重要组成部分,类概念可划分为上位水平、基本水平和下位水平。根据"oddball"范式,该课题使用国内省份、城市、景点以及少量动物和植物为实验材料,用传统的行为研究技术为实验手段,设计了语义启动任务,试图探讨启动范式下不同的类概念层级与信息提取之间的关系,研究提问线索对信息检索粒度的影响以及不同层次概念提取的差异,观察基本层加工优势的存在。实验结果表明,类概念层级间的优先加工会受到任务范式的影响,不同类概念水平之间的语义启动具有方向性。Class concept is an important part of our daily life, and it can be divided into three levels, the superordi- nate level, the basic level and the subordinate level. According to the ＂oddball＂ paradigm, traditional behavior meth- od is explored by using domestic provinces, cities, scenery spots and a few animals and plants as experimental mate- rials. In the present study, the relationship between different class concepts and information retrieval is attempted to be discussed. The preference processing of the basic level is checked, k is found that preference processing features between the class concept hierarchies will be affected by different task paradigms and the semantic priming between class concept hierarchies has direction.
