目标和干扰刺激不同步的情绪冲突效应研究

摘要

An affective priming paradigm is used to explore whether emotional conflict effect will be induced by asynchronous target and distractor and what special effects will occur in such condition .The results show that asynchronous target and distractor can also induce emotional conflict effect .Besides the classical “conflict adaptation effect” ,a special sequential effect ,namely the congruency effect of consecutive trials ,also occurs in the asynchronous emotional conflict . Whether these conflicts will occur is associated with the presentation duration of target stimulus . The present study demonstrates the crucial role of the stimulus presentation duration in emotional conflict .%采用情绪启动范式，考察了目标和干扰刺激不同步的情况下是否会出现情绪冲突，以及可能造成的特殊效应。结果发现：1）“不同步”的情绪刺激也能导致情绪冲突效应；2）除了情绪冲突现象中存在经典的“冲突调整效应”外，还发现了一类特殊的序列调整效应---试次（trial）间的一致性效应；3）上述效应的出现与否与目标刺激的呈现时间密切相关。该结果表明，刺激的呈现时间是情绪冲突现象中一个重要的变量。
