Correlations among ambiguous figures, curiosity, and spatial ability.

For 29 college students (6 men, 23 women) who passively viewed in each of 6 blocks both the Schroeder stair and the Necker cube for 3 min. apiece with one 3-min. rest between viewings, their frequency of reversals, sex, GPA, scores on the Wechsler Adult Intelligence Scale Information subtest, the two-dimensional Test 8, and the three-dimensional Test 9 of the Multiple Aptitude Test, measuring spatial ability, and three curiosity measures--the Which-to-Discuss Test, the Maze test, and the Ontario Test of Intrinsic Motivation--were not significantly correlated by Pearson's method with the number of ambiguous figure reversals.
