Fig. 3.

Baseline-corrected alpha power in C4 (left) and P4 (right) electrode clusters over time at 6.5 months (dashed line) and 9.5 months (solid line) during the scrambled (red), congruent (green), and incongruent (blue) conditions. Time zero is the start of the adult actor’s head turn. The vertical dashed lines indicate the end of the observed head turn, which was followed by a static period of adult gaze towards the object. Error bars represent +/− standard error (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article).
