Integration of compatible or incompatible emotional valence and semantic information is an essential aspect of complex social interactions. A modified version of the Implicit Association Test (IAT) called Dual Valence Association Task (DVAT) was designed in order to measure conflict resolution processing from compatibility/incompatibly of semantic and facial valence. The DVAT involves two emotional valence evaluative tasks which elicits two forms of emotional compatible/incompatible associations (facial and semantic).
Behavioural measures and Event Related Potentials were recorded while participants performed the DVAT.
Behavioural data showed a robust effect that distinguished compatible/incompatible tasks. The effects of valence and contextual association (between facial and semantic stimuli) showed early discrimination in N170 of faces. The LPP component was modulated by the compatibility of the DVAT.
Results suggest that DVAT is a robust paradigm for studying the emotional interference effect in the processing of simultaneous information from semantic and facial stimuli.
整合相容或不相容的情感效价和语义信息是复杂社会互动的一个重要方面。为了测量语义和面部效价的相容性/不相容性对冲突解决处理的影响,设计了一种称为双效价联想任务(Dual Valence Association Task,DVAT)的内隐联想测验(Implicit Association Test,IAT)的修正版。DVAT 涉及两个情感效价评价任务,引发两种形式的情感相容/不相容联想(面部和语义)。
参与者在执行 DVAT 时记录了行为测量和事件相关电位。
行为数据显示了一种强大的效应,可以区分相容/不相容的任务。效价和上下文关联(面部和语义刺激之间)的影响在 N170 中对面部表现出早期区分。LPP 成分受 DVAT 的兼容性调节。
结果表明,DVAT 是一种强大的范式,可用于研究同时处理来自语义和面部刺激的信息时的情绪干扰效应。
