摘要
采用计算机快速系列视觉呈现技术,以反应时为指标,利用命名法,从工作记忆容量个体差异的角度,探讨汉语句子阅读中的语境效应。将句子的语境效应分为两个来源:一个是自动激活扩散的词汇之间的语义启动,另一个是相互作用的句子水平的主题启动。结果表明:词汇间的语义启动不受工作记忆容量的影响,并且不易受到无关记忆任务的干扰。句子水平的主题启动会受到工作记忆容量的影响:工作记忆广度较高的读者能出现主题水平的语境效应,但是在无关记忆任务的干扰下,句子主题水平的语境效应消失;低广度的读者在无外部记忆负荷和有外部记忆负荷两种条件下都没有出现主题水平的语境效应。工作记忆容量对那些需要较多认知资源的加工过程产生显著的影响,实验结果符合工作记忆容量限制理论。
This study investigated the context effect during Chinese sentence reading. Naming task was used via rapid serial visual representation with reaction time as index. Context effect comes from two sources： the lexical semantic priming and the sentential thematic priming which were investigated separately here. The results indicated that （ 1 ） The lexical semantic priming was found from all the subjects under the two conditions ; （2） there was thematic priming in high-span readers except under the interference condition, but never in low-span readers. It supports the theory of working memory capacity constraint that the cognitive processes depending on abundance resources are constrained by working memory capacity.
