Hand-Eye Coordination. (A–D) Each individual is represented by a circle. The group mean is represented by the solid line, and the standard error is represented by the dotted lines. (A) Groups did not differ in the proportion of time acting upon a toy that they spent looking to the target toy (B) or to another toy. (C) Groups also did not differ in the duration of looks to the acted upon toy (D) or to the duration of looks to a non-in-hand toy while acting on a different toy.
