Alterations in audiovisual simultaneity perception in amblyopia
Amblyopia is a developmental visual impairment that is increasingly recognized to affect higher-level perceptual and multisensory processes. To further investigate the audiovisual (AV) perceptual impairments associated with this condition, we characterized the temporal interval in which asynchronous auditory and visual stimuli are perceived as simultaneous 50% of the time (i.e., the AV simultan...
متن کاملThe development of the perception of audiovisual simultaneity.
We measured the typical developmental trajectory of the window of audiovisual simultaneity by testing four age groups of children (5, 7, 9, and 11 years) and adults. We presented a visual flash and an auditory noise burst at various stimulus onset asynchronies (SOAs) and asked participants to report whether the two stimuli were presented at the same time. Compared with adults, children aged 5 a...
متن کاملDynamic Perceptual Changes in Audiovisual Simultaneity
BACKGROUND The timing at which sensory input reaches the level of conscious perception is an intriguing question still awaiting an answer. It is often assumed that both visual and auditory percepts have a modality specific processing delay and their difference determines perceptual temporal offset. METHODOLOGY/PRINCIPAL FINDINGS Here, we show that the perception of audiovisual simultaneity ca...
متن کاملRecalibration of audiovisual simultaneity in speech
Recent studies have shown that the audio-visual synchrony is recalibrated after adaptation to a constant timing difference between auditory and visual signals (i.e. temporal recalibration). Here we investigated whether the temporal recalibration occurs for audio-visual speech using an off-line adaptation method. After 3 minutes of lag observation, the audio-visual synchrony is recalibrated towa...
متن کاملBayesian Calibration of Simultaneity in Audiovisual Temporal Order Judgments
After repeated exposures to two successive audiovisual stimuli presented in one frequent order, participants eventually perceive a pair separated by some lag time in the same order as occurring simultaneously (lag adaptation). In contrast, we previously found that perceptual changes occurred in the opposite direction in response to tactile stimuli, conforming to bayesian integration theory (bay...
