Crossmodal Direct Priming between Vision and Touch

概要

This study examined whether a letter prime presented in one modality facilitate a subsequent response to the same letter target presented in the other modality. A prime and a target were presented either in vision or touch. The task was a go/no-go task, in which subjects were required to press a key as quickly as possible if the target was either the letter L or T (go trials) and refrain from responding if the target was a 5-dot pattern (no-go trials). Results from two experiments showed facilitatory priming effects in both vision-touch (VT) and touch-vision (TV) modality pairs at both short and long target onsets. This suggests that the visuotactile crossmodal priming effects endure for a certain period of time and that tactile stimuli take time to be processed.
