口头和手动Stroop冲突性质区别的新证据

使用斯特鲁普任务变式,利用汉字音、形、义三维度来研究口头和手动斯特鲁普任务加工机制的差异.研究发现:口头斯特鲁普任务的干扰效应主要来自反应输出阶段的反应冲突,而手动斯特鲁普任务的干扰效应既来自语义编码阶段的语义冲突,又来自反应输出阶段的反应冲突,但以语义冲突为主.因此,口头和手动斯特鲁普任务的加工机制的差异是由于干扰效应产生于不同的编码阶段以及不同的冲突类型引起的.

A New Evidence of the Distinction of Vocal and Manual Stroop Tasks in Conflicting Types

In the present study,the phonological,morphological and semantic dimensions of Chinese characters were used in Stroop-like tasks to research the distinction between the vocal and manual Stroop tasks.The results revealed that the response conflict which occurred in response output led to the Stroop interference effect in the vocal Stroop task,whereas the interference effect in the manual Stroop task was attributed to the semantic conflict occurring in semantic encoding and the response conflict at the stage of response output,the semantic conflict being the primary factor.It is,therefore,concluded that the differences in the processing mechanisms of vocal and manual Stroop tasks originate from the fact that their Stroop interference effects occur at different encoding stages and are of different conflict types.
