摘　　要：本研究探讨了不同案件类型、不同性别及给予不同的事件后信息对目击证言的影响,征集了男女大学生被试101名,进行了实验研究,研究结果如下:(1)以主体信息的记忆成绩为因变量,性别、案件类型和事件后信息为自变量,得出案件类型主效应显著,事件后信息的主效应显著,性别主效应以及各因素的交互作用都不显著;(2)以情境信息的记忆成绩为因变量,性别、案件类型和事件后信息为自变量,得出事件后信息主效应显著,案件类型和事件后信息之间交互作用效应显著;(3)不同性别、接受不同案件信息的被试对不同信息记忆的确信程度有所不同。The experiment was designed as 2 （type of event） × 2 （gender） × 2 （postevent information）, with 101 participants in it. The main results were： （1）With the memory performance of subject information as a dependent variable, and the gender, type of event, post-event information as the independent variables, we found the type of event had a main effect, and the post-event information also had a main effect. The main effect of gender and interaction between gender and other factors were not found ; （2） With the memory performance of context information as a dependent variable, and the gender, type of event, post-event information as the independent variables, we found the post-event information had a main effect. The interaction effect between the type of event and the post-event information reached a significant level; （3）Participants who were different in gender, and received different typs of events had different degrees of accuracy concerning memory of different kinds of information.
