Abstract:
Spontaneously occurring speech is often seamlessly accompanied by hand gestures. Detailed observations of video data suggest that speech and gesture are tightly synchronized in time, consistent with a dynamic interplay between body and mind. However, spontaneous gesture-speech synchrony has rarely been objectively quantified beyond analyses of video data, which do not allow for identification of kinematic properties of gestures. Consequently, the point in gesture which is held to couple with speech, the so-called moment of “maximum effort”, has been variably equated with the peak velocity, peak acceleration, peak deceleration, or the onset of the gesture. In the current pre-registered report, we provide novel evidence from motion-tracking and acoustic data that peak velocity is closely aligned, and shortly leads, the peak pitch (F0) of speech. We propose to replicate this in a more comprehensive sample, so as to provide a rigorous quantification of gesture-speech synchrony. ...
