Narrowing of intersensory speech perception in infancy.

The development of face perception in infancy: intersensory interference and unimodal visual facilitation.

Although research has demonstrated impressive face perception skills of young infants, little attention has focused on conditions that enhance versus impair infant face perception. The present studies tested the prediction, generated from the intersensory redundancy hypothesis (IRH), that face discrimination, which relies on detection of visual featural information, would be impaired in the con...

Cross-Modal Matching of Audio-Visual German and French Fluent Speech in Infancy

The present study examined when and how the ability to cross-modally match audio-visual fluent speech develops in 4.5-, 6- and 12-month-old German-learning infants. In Experiment 1, 4.5- and 6-month-old infants' audio-visual matching ability of native (German) and non-native (French) fluent speech was assessed by presenting auditory and visual speech information sequentially, that is, in the ab...

The influence of infant-directed speech on 12-month-olds' intersensory perception of fluent speech.

The present study examined whether infant-directed (ID) speech facilitates intersensory matching of audio-visual fluent speech in 12-month-old infants. German-learning infants' audio-visual matching ability of German and French fluent speech was assessed by using a variant of the intermodal matching procedure, with auditory and visual speech information presented sequentially. In Experiment 1, ...

Developmental Psychology The Development of Face Perception in Infancy: Intersensory Interference and Unimodal Visual Facilitation

I can see what you said: infant sensitivity to articulator congruency between audio-only and silent-video presentations of native and nonnative consonants

We examined infants’ sensitivity to articulatory organ congruency between audio-only and silent-video consonants (lip vs. tongue tip closure) to evaluate three theoretical accounts of audio-visual perceptual development for speech: 1) learned audio-visual associations; 2) intersensory perceptual narrowing; 3) amodal perception of articulatory gestures. Effects of language experience were invest...
