Visual bodily signals and conversational context benefit the anticipation of turn ends - Experiment 2

Experiment 2 from ter Bekke et al. (2024, Cognition). One core ingredient to turn coordination is the anticipation of upcoming turn ends so as to be able to ready
oneself for providing the next contribution. In this pre-registered follow-up experiment, we manipulated the visibility of the speaker’s head, eyes and
upper body (i.e. torso + arms). Participants were better able to anticipate turn ends when the speaker’s upper body was visible, suggesting a role for manual gestures in turn end anticipation. Preprocessed data and analysis scripts can be found here: https://osf.io/4gtw5/wiki?wiki=sn49k
