Four groups of children (N=80; C.A. 6.6. to 12.5; M.A. 7.9 to 14.7) were tested for ability to reproduce five-element two- and three-dimensional patterns. Significant interaction and main effects were found. Three-dimensional pattern performance increased with age; all ages performed well on two-dimensional patterns. (Author/DB)
