To examine functional asymmetry in children's manipulation, 103 right-handed subjects (4, 5 and 6-year-olds) were given the unimanual task which included both sequential and spatial factors. The main results were as follows: (a) Subjects performed better with their right hands for the sequential factor, and with their left hands for the spatial factor. (b) Left-hand predominance was observed in correct responses of both sequential and spatial factors. (c) Though all subjects were right-handed, different performances were shown by the groups of latent handedness measured by the Crossing-arms test. These results were interpreted as a reflection of functional asymmetry of the brain, and it was suggested that the developmental process of manipulation was different from that of handedness.
