Event-related potentials evidence for long-term audiovisual representations of phonemes in adults.

ABSTRACT: The presence of long-term auditory representations for phonemes has been well-established. However, since speech perception is typically audiovisual, we hypothesized that long-term phoneme representations may also contain information on speakers' mouth shape during articulation. We used an audiovisual oddball paradigm in which, on each trial, participants saw a face and heard one of two vowels. One vowel occurred frequently (standard), while another occurred rarely (deviant). In one condition (neutral), the face had a closed, non-articulating mouth. In the other condition (audiovisual violation), the mouth shape matched the frequent vowel. Although in both conditions stimuli were audiovisual, we hypothesized that identical auditory changes would be perceived differently by participants. Na
