文摘 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,并且与其抑制和注意等执行功能有关。
其他语种文摘 This study explored the role of frontal lobe in associative perceptual priming and perceptual priming effects. Twenty-five frontal lobe lesioned patients and 18 age, gender and education matched control subjects were examined. Each patient did general basic neuropsychological tasks, then they did color naming (25 patients) , word naming (11 patients) and corresponding recognition tasks in counterbalanced order. The results demonstrated that in both speeded naming tasks, the patients did not show any facilitation on the reaction time of the old colored word relative to the recombined ones, sugges-ting their impairments both in associative priming and perceptual priming. The recognition memory of mild memory deficit patients was not significantly different from that of the controls. The correlation analysis showed that there were modest but significant correlation between associative priming, perceptual priming effects and some of frontal lobe functions. These re-sults suggest that the frontal lobe plays a role in associative perceptual priming and perceptual priming effects, probably mediated by its executive functions such as inhibition and selective attention.
