Figure 1.

Test trial sequence for adults and children. Participants were instructed to locate either the half-circle segmentation target (highlighted here by the red solid circles) or the empty-space integration target (indicated by the solid blue circle). The segmentation target is visible only to the extent that Displays A and B are visually segmented, and the integration target is visible only to the extent that Displays A and B are visually integrated. An ISI separated Displays A and B, directly influencing the likelihood of integrating or segmenting the displays and thereby driving the detectability of the respective targets. In each trial, two AB pairs were presented.
