DEVELOPMENT OF THE RIGHT EAR ADVANTAGE IN DICHOTIC-LISTENING TEST - COMPARISON OF THE FINDINGS BY CROSS-SECTIONAL AND LONGITUDINAL-STUDIES

The right ear advantage in dichotic listening test for VCV word pairs was investigated using both longitudinal and cross-sectional methods with children whose age ranged from four to six. The degree of a right ear advantage and the population of those who showed a right ear advantage increased with age in the cross-sectional method. In the longitudinal method, however, the above findings could not be confirmed. These results suggest that the application of dichotic listening test may be inappropriate to young children. © 1990, The Japanese Psychological Association. All rights reserved.
