摘要
本文运用ERP技术探讨老龄化对汉语因果复句加工的影响.实验结果显示,与年轻人相比,老年人在判断因果复句的合理性时,反应时更长,正确率更低.在加工因果违反句的关键词时,老年人未出现显著的N400成分,但出现了全脑范围的晚期正波,而年轻人只在大脑左侧出现了 N400成分.这表明老年人对汉语因果复句的理解能力出现了退化,本文认为这是由于老年人在加工因果复句时,加工效率下降,无法有效利用语境对词汇进行即时的预测加工,因此在关键词与语境信息不一致时,老年人未出现明显的N400效应,需要在后期进行再分析加工,从而产生了晚期正波效应.
Abstract
Using event-related potentials(ERPs),the present study explores the effects of aging on the processing of Chinese causal complex sentences.The experimental results show that older adults have longer response time and lower accuracy rate when judging the plausibility of causal complex sentences compared to younger adults.When reading critical words in implau-sible causal sentences,older adults don't show a significant N400 component but a widespread late positive complex(LPC),whereas younger adults show an N400 component only on the left brain.This finding suggests a decline in language compre-hension in the older adults when reading Chinese causal complex sentences,which may be due to the fact that the processing efficiency of older adults decreases,and that they are unable to effectively utilize the context to predict and process the critical words immediately.Thus,when the critical words are incongruent with the previous context,older adults don't show an obvi-ous N400 effect,and they must reanalyze the words at a later stage,which gives rise to an LPC effect.
