RELATIONSHIPS AMONG AGE, SEX, AND LATERAL DOMINANCE FOR 3- TO 6-YEAR-OLD CHILDREN PERFORMING UNILATERAL STANCE

The connection between lateral dominance and force of handgrip was investigated by means of a repeated-measures design. 521 children participated. Performance on a paper-and-pencil task and force of handgrip were measured at the beginning of the first year at school and at the end of the first and of the second years at school. On the paper-and-pencil task 84% of the children were classified as right-handers, 8% as left-handers, and 8% as ambidexterous. About 2% of children classified as right-handers at the beginning of the first year at school were classified as left-handers at the end of the second year at school while 18% of left-handers shifted to right-handedness. 52% of children attained their best performance on handgrip with the right hand and 39% with the left hand. No differences could be found either for the right or for the left hand in force of handgrip between right- and left-handed and ambidexterous children. For right-handers, however, the more skilled hand showed superior performance in force of handgrip. These results indicate that left-handers are less strongly handed than right-handers.

The literature suggests that schizophrenics exhibit reduced or reversed cerebral lateral dominance relative to normal control subjects. An hypothesis which predicted reduced or reversed cerebral laterality for schizophrenics was tested on 60 young, familially right-handed males, with 20 men in each of the following three groups: schizophrenic inpatients, nonschizophrenic psychiatric inpatient controls, and normal controls. The subjects were administered a battery of seven measures of cerebral laterality. The application of multivariate statistical techniques showed groups did not differ significantly in the degree or the direction of their cerebral lateral dominance. Also there were no significant correlations between the measures of laterality. The findings suggest that cerebral lateral dominance is not necessarily altered concomitantly with psychopathology but rather that it is a complex phenomenon which may not be reliably determined on the basis of simple behavioral characteristics.
