词汇的概念义和情绪义加工的时间进程研究

The Time Course of Conceptual Semantic and Affective Semantic Processing of Words

目的:对词汇的概念义和情绪义加工的时间进程进行直接的对比研究。方法:以50名健康大学生为被试,采用一种特殊的词汇——双意义情绪词,通过设置不同的SOA条件(50毫秒和300毫秒),同时考察了词汇的语义启动和情绪启动效应,要求被试进行词汇判断任务。结果:在短SOA(50毫秒)条件下,词汇的语义启动效应和情绪启动效应均显著,且两者之间无显著差异;在长SOA(300毫秒)条件下,词汇的语义启动效应显著,但未发现情绪启动效应。结论:词汇概念义的加工同时包括了自动化和控制性的加工过程,而情绪义的加工只包含了自动化的加工过程,表明词汇的概念义和情绪义加工具有不同的时间进程。

Objective： To directly compare the time course of the conceptual semantic and affective semantic process- ing of words using the comparative approach. Methods： Fifty healthy college students participated in the experiment. A special type of words, named dual-meaning words, which had both conceptual meaning and affective meaning, were used, We adopted simultaneously the semantic priming and affective priming paradigm with a short （50 ms） and long （300 ms） SOA （stimulus onset asynchrony）. The subjects were asked to perform a lexical decision task. Results： At the short SOA condition, there were both significant semantic and significant affeetive priming effects. But at the long SOA condition, on- ly significant semantic priming effect was found. Conclusion： These findings suggest that conceptual semantic processing of words contains both automatic and controlled processes, but affeetive semantic processing is more an automatic one, in- dicating different time courses of the conceptual and affective semantic processing of words.
