The "correspondence problem" is a classic issue in vision and cognition. Frequent perceptual disruptions, such as saccades and brief occlusion, create gaps in perceptual input. How does the visual system establish correspondence between objects visible before and after the disruption? Current theories hold that object correspondence is established…

Four experiments examined the perceptual features used by 4.5- to 11.5-month olds to individuate objects involved in occlusion events. Results indicated that 4.5-month olds used shape and size features to individuate objects in occlusion events. By 7.5 months, infants used pattern, and by 11.5 months, they used color to reason about object…

Tested 160 children on a Stroop-like day-night test that involved 2 rules. Also tested for whether remembering two rules alone was sufficient to cause difficulty. Concludes that the requirement to learn and remember two rules is not in itself sufficient to account for the poor performance of younger children (under five) in the experiment. (DR)
