Figure 2.

(A) The results from Experiment 1a, in which the interaction partner could either follow the gaze of the participant to engage in joint attention (JA) or avert his/her gaze to the other object to engage in non-joint attention (NJA). (B) In Experiment 1b the interaction partner always engaged in JA, only the latency of the gaze reaction is varied. For better comparability, the joint attention data of Experiment 1a (JA in the context of NJA as another option to act) are plotted together with the data from Experiment 1b (JA only).
