Abstract:
In Study I, 24 children at the average ages of 41.1 and 46.1 mo. were presented dichotic digits while another 27 children were tested at average ages of 40.0, 49.6, and 54.6 mo. In Study II, 40 children were tested at average ages of 50.7 and again at 91.8 mo. No significant change in right-ear advantage (REA) appeared across 4- or 9-mo. intervals; however, significant increases were found over the 14-mo. (Study I) and 41-mo. (Study II) intervals. There were no significant effects of sex or phenotypic or family history of handedness.
