Two hundred participants, 50 in each of 4 age ranges (19-29 years, 30-49 years, 50-69 years, 70-90 years) were tested for short-term working memory, speed of processing, and online processing of 3 types of sentences in which an initially assigned syntactic structure and/or semantic interpretation had to be revised. Self-paced reading times were longer for the segments that signaled the need for revision; there also were interactions of age and sentence type and speed of processing and sentence type, but not of working memory and sentence type on reading times for these segments. The results provide evidence that working memory does not support the processes that revise the structure and interpretation of sentences and discourse.
200名参与者,分为4个年龄组(19 - 29岁、30 - 49岁、50 - 69岁、70 - 90岁),每组50人,接受了短期工作记忆、处理速度以及对3种类型句子的在线处理测试,这些句子需要对最初指定的句法结构和/或语义解释进行修改。对于表明需要修改的部分,自定步速阅读时间更长;在这些部分的阅读时间上,还存在年龄与句子类型、处理速度与句子类型之间的交互作用,但工作记忆与句子类型之间不存在交互作用。结果表明,工作记忆并不支持修改句子和语篇结构及解释的过程。
