Whereas infants and apes both pointed more frequently towards the other side when the reward was located there (Wilcoxon signed-ranks test; infants: T + = 45.0, N = 9, p = .004; apes: T + = 59.5, N = 11, p = .018), only infants exhibited a marginal trend to direct more pointing gestures towards the other side when the experimenter was attentive (Wilcoxon signed-ranks test; infants: T + = 39.0, N = 9, p = .051; apes: T + = 40.0, N = 11, p = .544).
