Figure 3

The narrow-screen green ball-red ball test event used in Wilcox and Chapa (2004) and in Experiments 1 and 2. The ball seen to the left of the screen was green and to the right of the screen was red. The screen was too narrow to hide both balls simultaneously. Prolonged looking to the narrow-screen green ball-red ball test event is taken as evidence that infant's individuated the objects (i.e., used the color differences to signal the presence of two objects and recognized that both objects could not fit simultaneously behind the screen; see Wilcox & Woods, 2009 for a review of the evidence).
