From: Youngsters do not pay attention to conversational rules: is this so for nonhuman primates?
Playback experiments.
Visual attention (i.e. duration of looking towards the speaker in the 30 seconds ‘after’ minus 30 seconds ‘before’ playback) paid to appropriate and inappropriate vocal exchanges (respecting or not the turn-taking rule) in relation to listener's age. *P≤0.05, NSP>0.05.
