Relationships Between Language and Gesture in Normally Developing and Late-Talking Toddlers

Abstract

Seventeen toddlers with specific expressive language delay (14 boys and 3 girls between 18 and 33 months of age) were compared to two control groups, one matched for language production and the other matched for age and language comprehension, on measures of spontaneous and imitated gesture production. Late talkers performed like age/comprehension-matched controls on all experimental measures of gesture production and on production of later appearing, more symbolic gestures as reported by parents. Late talkers performed like language-matched controls on earlier appearing communicative gestures and gestural routines as reported by parents. All three groups produced more gestures in canonical imitation conditions than spontaneously. Results are discussed in the contexts of the Local Homology Model and characteristics of toddlers with specific expressive language delay.
