| Abstract | This study was designed to mvestigate differences in the degree of manual latemlization between right-handed and left-handed nmmal boys. Sixtythree 5, 7, and 9 year olds were tested on the Minnesota Rate of iVlanipulation Test (displacing subtest and turning subtest), the Finger Tapping Test, the Purdue Pegboard (placing subtest and assembly subtest), and the Southern Californza Motor Accuracy Test-Revised. Significant differences between rightand lefthanded subjects were obtained on two of the six measures, and a third measure approached significance, with less lateralization among the left handen than among the rzght handeTS Subsequent analyses indicated that differences in lateralization were significant or near-significant in the 5 and 7 )Iear' olds. By 9 yeaTS of age, rightand left-handed subjects no longer differed 1n the degree of laterality. Differences in degree of laterality, or the lack of such differences, between young nghtand left-handed boys might be a function of the nature of thl' fine motor task or a function of the child's previous experienCf with the task. |
