Gestures of six young adults were transcribed from videotaped narrations. Iconic, or imitative, gestures were found to have a tendency to depict whole scenes, and to correlate positively with motions implied in accompanying verbs. Gestures were found to be marked for such contrasting grammatical features as agent and patient, and transitive and intransitive. "Beats," or imprecise gestures, were not found to have the correlations characterizing iconic gestures. Furthermore, iconics correlate positively and beats negatively with handedness. Many metaphoric gestures, which iconically depict the vehicle of a metaphor, were identified. The sum of the evidence shows a close connection between the form of gestures and the organization of speech. This is interpreted to mean that concrete conceptual representations (or models) are involved at different levels of speech organization. (JB)
