The eye and the hand may sample different properties of the same stimulus, with the properties most salient to one being different from those most salient to the other. This possibility is confirmed by asking children in kindergarten and second grade to judge which of two changes to a figure, both discriminable, leave the figure least changed. Visually, a change in curvature is highly significant, but a change in orientation is not. The reverse is usually true haptically. The haptic response appears based on the way the hand and its activity offer reference points for determining a change in a focal part of the figure.
