Temporal binding window of Audio-Visual Speech Stimuli in Infants

Order Similar Paper

This study explores multisensory perception in infants, specifically the
temporal binding window of Audio-Visual Speech Stimuli.

The experiment focuses on the effect of changes in gender congruency of
face/voice stimuli on the detection of changes in temporal synchrony
between audio and visual components of stimuli during Multisensory
Binding of Audio-Visual Speech Stimuli in 8-10 month old Infants.

To test this we plan to employ a habituation paradigm similar to that
use by Lewkowicz (1996) to measure infants’ perception of
auditory-visual temporal synchrony.

Temporal binding window of Audio-Visual Speech Stimuli in Infants

Before the actual test trials, the infants will be habituated with a
synchronous face-voice pairing that will be either matched for gender or
mismatched.

We will then show 8-10-month-old infants video clips of faces and voices
which will be presented either synchronously or asynchronously, and we
will measure their looking time to the videos.

Finding out whether infants’ temporal binding window is also affected by
congruency effect between the face and the voice of the speak might shed
light into the amount of experience needed with multisensory stimuli in
order to detect top-down effects on perception.
