IAT效应在不同目标概念水平上的差异研究

采用IAT实验设计，考察大学生对不同概念词的内隐态度之间的差别。结果发现，八组实验材料都产生了显著的IAT效应；不同性别的测验材料的IAT效应间不存在显著差异，不同喜好程度的测验材料的IAT效应间存在显著差异，且两个因素存在显著的交互作用。研究表明，IAT效应既可在上位概念水平上产生，亦可在下位概念水平上产生。

The Difference of IAT Effects on Different Levels of Target Concept

This study examined the difference of students' implicit attitudes toward different lists of words representing the same pair of targettconcepts (the old/the young). The result showed that (1) all the eight sub-concepts as a whole generated significant I AT effect, (2) while no discrepancy was found between I AT effects of different genders, there did exist significant difference between IAT effects of different valence, and moreover, there was interaction between gender and valence. The conclusion drawn from this study is that IAT effect can be generated both on the concept level and on the sub-concept level.
