Examines the interrelationships of task performances and developmental changes of 4-, 6-, and 8-year-olds. Significant developmental changes were observed on transposition, cue interference, and spatial memory. The pattern of intercorrelations between tasks suggested a high degree of correspondence across tasks. (ST)
