摘　　要：以额叶损伤病人为被试 ,探讨在知觉型联想启动和知觉启动中 ,额叶的作用及其内在机制。实验任务包括颜色命名和词命名任务 ,以及相应的再认任务。结果表明 ,额叶损伤病人在颜色命名和词命名任务中 ,对旧词和重组颜色词的命名时间都没有明显差别 ,联想启动和颜色启动效应受损 ,但轻度记忆损伤病人与正常对照组之间的再认成绩相似。相关分析发现联想启动和颜色启动与额叶的多项功能有中度相关。这表明 ,额叶参与了知觉型联想启动效应和知觉启动 。This study explored the role of frontal lobe in associative perceptual priming a nd perceptual priming effects. Twenty-five frontal lobe lesioned patients and 1 8 age, gender and education matched control subjects were examined. Each patient did general basic neuropsychological tasks, then they did color naming (25 pati ents), word naming (11 patients) and corresponding recognition tasks in counterb alanced order. The results demonstrated that in both speeded naming tasks, the p atients did not show any facilitation on the reaction time of the old colored wo rd relative to the recombined ones, suggesting their impairments both in associa tive priming and perceptual priming. The recognition memory of mild memory defic it patients was not significantly different from that of the controls. The corre lation analysis showed that there were modest but significant correlation betwee n associative priming, perceptual priming effects and some of frontal lobe funct ions. These results suggest that the frontal lobe plays a role in associative pe rceptual priming and perceptual priming effects, probably mediated by its execut ive functions such as inhibition and selective attention.
