Rapid visual engagement in neural processing of detailed touch interactions.

ABSTRACT: Touch perception is an inherently multisensory process in which vision plays an essential role. However, our understanding of how vision encodes sensory and emotional-affective aspects of observed touch, and the timing of these processes, remains limited. To address this gap, we investigated the neural dynamics of visual touch perception using electroencephalographic (EEG) recordings from participants who viewed videos depicting detailed tactile hand interactions from the Validated Touch-Video Database. We examined how the brain encodes basic body cues, such as hand orientation and viewing perspective, in addition to sensory aspects, including the type of touch (e.g., stroking vs. pressing; hand vs. object touch) and the object involved (e.g., knife, brush), as well as emotional-affective
