Abstract
Speakers of all languages gesture, but there are differences in the gestures that they produce. Do speakers learn language-specific gestures by watching others gesture or by learning to speak a particular language? We examined this question by studying the speech and gestures produced by 40 congenitally blind adult native speakers of English and Turkish (n = 20/language), and comparing them with the speech and gestures of 40 sighted adult speakers in each language (20 wearing blindfolds, 20 not wearing blindfolds). We focused on speakers' descriptions of physical motion, which display strong cross-linguistic differences in patterns of speech and gesture use. Congenitally blind speakers of English and Turkish produced speech that resembled the speech produced by sighted speakers of their native language. More important, blind speakers of each language used gestures that resembled the gestures of sighted speakers of that language. Our results suggest that hearing a particular language is sufficient to gesture like a native speaker of that language.
