Three groups of 45 children of ages 3 to 6 were motivated to find a reward in a box which could be opened only by a key hidden in a 2d, unlocked box, in which were several irrelevant objects, and the placement of the key among them differed for each of the 3 groups. Two sets of goal boxes, separated spatially, and containing different test objects, were used. After 3 visits to each set of boxes, a test for latent learning was made by asking S to find one of the test objects. Results: The ability to locate the test objects differed significantly from chance, and latent learning was shown. The ability to locate the object increased significantly with increasing chronological age. The frequency of latent learning differed significantly, depending upon the placement of the key in relation to the test object.
