Abstract:
Recent studies have shown that audiovisual synchrony is recalibrated after exposure to asynchronous auditory and visual signals. This temporal recalibration has been shown only under a dual-task situation for speech signals. Here we examined whether the temporal recalibration occurs for audiovisual speech in a single-task situation using an offline adaptation method. In the experiment, participants were exposed to synchronous or asynchronous audiovisual syllables (either congruent or incongruent) for 3 min. The adaptation phase was followed by test trials, in which participants judged whether the auditory or visual stimulus was presented first. Results showed shifts in the point of subjective simultaneity and the sensitivity. Our results suggest that attention to adaptation stimuli is necessary to induce temporal recalibration for speech.

Interference: Path Lengths
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
