Individual reaction times in Experiment 1.

<p>Each subplot represents one individual. Six-month-olds are plotted in blue, eight-month-old in red. Dashed horizontal lines are the anticipation threshold of 200 ms. There was no systematic difference between age or gender groups. Four representative individuals were selected and ordered based on their average reaction times. (A) Very frequent anticipations. (B) Frequent ancitipations. (C) Few anticipations. (D) No anticipations.
