Gestures and speech (Psycological investigations )
The bookexamines three major hypotheses concerning gesture and speech: First, gestures are identified with speech as a "body language" and an analysis of vocal and gestural communication is made from an ethological perspective; second, a system of "nonverbal communication" may be assumed, separate from language and specialized in the expression of affective states and interpersonal attitudes; third, gestures and speech might form two distinct but connected domains and the name of their interactions be specified
