High-ability Jamaican students in grades one, three, five, seven, and nine were asked to draw five three-dimensional objects (cuboid, pyramid, cylinder, cone, cube) from memory, and with the object visible; later they were asked to select the best sketch of each solid from among several presented. Drawings and selections were scored for primitiveness on a five-point scale, and scores on the three tasks were compared. The two drawing scores were combined; reliabilities computed were .93 (combined drawing) and .53 (selection). Developmental trends, sex differences, and correlations of these scores with spatial tests, illusion tests, and background variables were examined. (SD)
