Simon效应及其反转现象作用机制的研究

研究运用任务干扰的实验范式,试图从探讨刺激出现的空间位置与反应效果之间的关系来推测Simon效应及其反转现象的作用机制。结果表明:(1)当相关刺激-反应匹配不相容时,颜色刺激在左、右位置呈现,当明显标记反应键时,出现Simon效应的反转。(2)当手指遮住反应键的标记时,没有反转。(3)当颜色刺激在中央位置,声音在左、右耳发生时,没有反转。说明显示-控制排列对应性是产生Simon效应反转的最重要因素,逻辑再编码只起到次要的作用。

A Research on the Functional Mechanism of the Simon Effect and Its Reversal

This research adopted the task interference experimental paradigm in exploring the relationship between stimulus spatial location and response result in order to infer the functional mechanism of the Simon effect and its reversal.The results indicate that the reversal of the Simon effect occured when the response keys were visibly labeled,but not when the fingers covered the labels.Moreover, even with visible labels,no reversal was evident when the colored stimuli were centered and tones occured in the left or right ear.It is suggested that,displaycontrol arrangement correspondence was the primary cause of the reversal of the Simon effect with logical recoding playing only a secondary role.
