Feeling what you hear: auditory signals can modulate tactile tap perception.

摘要: We tested whether auditory sequences of beeps can modulate the tactile perception taps (two to four per sequence) delivered index fingertip. In first experiment, and were presented simultaneously. The number in sequence either same as, less than, or more than simultaneously sequence. Though task-irrelevant (subjects instructed focus on stimuli), stimuli systematically modulated subjects' perception; other words responses depended significantly beeps. Such modulation only occurred when similar enough. second we automatic auditory-tactile integration depends simultaneity a bias be evoked are temporal asynchrony. Audition but this effect gradually disappeared asynchrony was introduced between stimuli. These results show that provided with sensory signals likely generated by stimulus, central nervous system (CNS) tends automatically integrate these signals.
