    Abstract

    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 investigated in 4- vs. 11- month-olds’ cross-modal perception of native (English stops) and nonnative (Tigrinya ejectives) consonant contrasts. The 4- month-olds showed an articulator-congruency preference for both native and nonnative consonants, but it was constrained by trial order. The 11-month-olds’ more complex cross-modal responses differed for native vs. nonnative speech, suggesting an effect of increased native language experience. Results are at odds with associative learning and perceptual narrowing, but consistent with experiential tuning of amodal perception for two distinct articulators.
