Two studies on developmental trends in dichhaptic lateralization for nonlinguistic stimuli were conducted on school-aged children. Study 1 included 60 students in Grades 1, 5, and 9. Study 2 included 200 students from Grades 2, 4, 6, 8, and 10. Both studies showed significant age-related increases in over-all dichhaptic accuracy. In Study 2 a significant left-hand advantage for all subjects as well as an over-all advantage for boys were noted. Significant interactions indicated different developmental trends for boys and girls but did not show clear patterns in the development of lateralization.
