【摘要】 已有研究证实,刺激预存知识表征对重复启动效应具有调节作用。然而,尚无刺激特征预存知识表征和特征转换调节该效应的报道。本研究以颜色诊断性假说为依据,对颜色特征的预存知识表征进行控制,旨在考察颜色特征的预存知识表征、特征转换及重复次数对重复启动效应的影响。结果显示:诊断色和非诊断色启动条件均产生了显著的重复启动效应,后者的效应更强;诊断色启动条件下,诊断色图形反应时的启动效应显著大于非诊断色图形;启动条件、图形类型和重复次数在正确率的启动效应上存在显著的交互作用。上述结果表明,重复启动效应为颜色诊断性和特征转换所调节,具有预存知识表征的诊断色的调节作用符合自上而下的加工观。更多还原

【Abstract】 Recent research has shown that the pre-existing memory representation of stimuli contributes to repetition priming effect. However,it is uncertain whether this effect will also be modulated by color pre-existing memory representation. To address this issue,we conducted a four-factor experiment: priming condition,object type,color type and repetition times. The task of priming stage was knowledge verification task– whether the presented color is nature or not and one object verification task was constructed to make a judgment about whether the presented figure has been studied or not. The results illustrated a significant repetition priming effect both for diagnostic color and non-diagnostic color,but more pronounced for the latter. The analysis of priming effect in accuracy revealed a three-way interaction among priming condition,feature transformation and repetition times.We suggest that repetition priming effect is modulated by color diagnosticity and feature transformation.Our results are consistent with the up-down processing automatic mechanism.更多还原
