Rapid recalibration to audiovisual asynchrony.
To combine information from different sensory modalities, the brain must deal with considerable temporal uncertainty. In natural environments, an external event may produce simultaneous auditory and visual signals yet they will invariably activate the brain asynchronously due to different propagation speeds for light and sound, and different neural response latencies once the signals reach the ...
متن کاملOn the audiovisual asynchrony of speech
The temporal synchrony of auditory and visual signals is known to affect the perception of audiovisual speech. Several papers have discussed the asymmetry of acoustic and visual timing cues. These results are usually based on subjective intelligibility tests and the reason is remained obscure. It is not clear that the observation is perception or production origin. In this paper the effect of a...
متن کاملAudiovisual asynchrony detection in human speech.
Combining information from the visual and auditory senses can greatly enhance intelligibility of natural speech. Integration of audiovisual speech signals is robust even when temporal offsets are present between the component signals. In the present study, we characterized the temporal integration window for speech and nonspeech stimuli with similar spectrotemporal structure to investigate to w...
متن کاملAudiovisual asynchrony detection for speech and nonspeech signals
This study investigated the “intersensory temporal synchrony window” [1] for audiovisual (AV) signals. A speeded asynchrony detection task was used to measure each participant’s temporal synchrony window for speech and nonspeech signals over an 800-ms range of AV asynchronies. Across three sets of stimuli, the video-leading threshold for asynchrony detection was larger than the audio-leading th...
متن کاملPutative mechanisms mediating tolerance for audiovisual stimulus onset asynchrony.
Audiovisual (AV) speech perception is robust to temporal asynchronies between visual and auditory stimuli. We investigated the neural mechanisms that facilitate tolerance for audiovisual stimulus onset asynchrony (AVOA) with EEG. Individuals were presented with AV words that were asynchronous in onsets of voice and mouth movement and judged whether they were synchronous or not. Behaviorally, in...
