Auditory speech appears to be linked to visual articulatory gestures and orthography through different mechanisms. Yet, both types of visual information have a strong influence on speech processing. The present study directly compared their contributions to speech processing using a novel word learning paradigm. Native speakers of French, who were…

Purpose: This study aimed to test whether (and how) somatosensory feedback signals from the vocal tract affect concurrent unimodal visual speech perception. Method: Participants discriminated pairs of silent visual utterances of vowels under 3 experimental conditions: (a) normal (baseline) and while holding either (b) a bite block or (c) a lip…

THROUGH PHOTOGRAPHS, CHARTS, AND ILLUSTRATIONS, THE DIFFICULTIES OF COMMUNICATION ARE PRESENTED IN THIS BOOK. TOPICS CONSIDERED FIRST ARE THE RECEIVING AND EVALUATING OF SENSORY EXPERIENCE, AND THE TRANSLATING OF THIS EXPERIENCE INTO SYMBOLS, INTO THE SILENT LANGUAGES OF TIME, COLOR, AND SPACE, AND INTO COMMON WORDS. THE EMPHASIS IS THEN SHIFTED…
