In 21 essays on communicative gesturing in the first two years of life, this vital collection demonstrates the importance of gesture in a child’s transition to a linguistic system. Introductions preceding each section emphasize the parallels between the findings in these studies and the general body of scholarship devoted to the process of spoken language acquisition. Renowned scholars contributing to this volume include Ursula Bellugi, Judy Snitzer Reilly, Susan Goldwin-Meadow, Andrew Lock, M. Chiara Levorato, and many others.
