Adaptation to audiovisual asynchrony modulates the speeded detection of sound

摘要: The brain adapts to asynchronous audiovisual signals by reducing the subjective temporal lag between them. However, it is currently unclear which sensory signal (visual or auditory) shifts toward other. According idea that auditory system codes information more precisely than visual system, one should expect find some shift of vision audition (as in ventriloquism effect) as a result adaptation signals. Given gives exact estimate time occurrence distal events (due fact arrival regarding an external event always closer at this occurred), opposite could also be expected. Here, we demonstrate participants' speeded reaction times (RTs) (but, critically, not visual) stimuli are altered following stimuli. After receiving "baseline" exposure synchrony, participants were exposed either auditory-lagging asynchrony (VA group) auditory-leading (AV group). results revealed RTs sounds became progressively faster (in VA slower AV increased, thus providing empirical evidence responses influenced asynchrony.
