This experiment used event-related potentials (ERPs) to study the tactile-visual information conflict processing in a tactile-visual pairing task and its modulation by tactile-induced emotional states. Eighteen participants were asked to indicate whether the tactile sensation on their body matched or did not match the expected tactile sensation associated with the object depicted in an image. The type of tactile-visual stimuli (matched vs. mismatched) and the valence of tactile-induced emotional states (positive vs. negative) were manipulated following a 2 × 2 factorial design. Electrophysiological analyses revealed a mismatched minus matched negative difference component between 420 and 620 ms after stimulus onset in the negative tactile-induced emotional state condition. This ND420-620 component was considered as a sign of the cross-modal conflict processing during the processing of incongruent tactile-visual information. In contrast, no significant mismatched minus matched negative difference component was found in the positive tactile-induced emotional state condition. Together, these results support the hypothesis that a positive emotional state induced by a positive tactile stimulation improves tactile-visual conflict processing abilities.

本实验使用事件相关电位（ERP）研究触觉-视觉配对任务中的触觉-视觉信息冲突处理及其受触觉诱发的情绪状态的调节。要求18名参与者指出其身体上的触觉与图像中描绘的对象相关的预期触觉是否匹配。触觉-视觉刺激的类型（匹配与不匹配）和触觉诱发的情绪状态（正与负）的效价按照2×2因子设计进行操作。电生理分析显示，在负触觉诱发的情绪状态下，在刺激开始后420到620毫秒之间，负匹配的负匹配负差成分不匹配。ND420-620组件被认为是在处理不一致的触觉-视觉信息期间进行跨模式冲突处理的标志。相反，在正触觉诱发的情绪状态条件下，未发现显着的失配减去匹配的负差异成分。总之，这些结果支持这样的假说，即由积极的触觉刺激引起的积极的情绪状态改善了触觉-视觉冲突处理能力。
