Lateral preference and style of cognition.
The relationship between cognitive ability and laterality was examined in terms of the relation of intelligence test scores to lateral preference. The factor analysis was performed on the variables of 12 tasks of the intelligence scale and total lateral preference. A slight relation was found between lateral preference and figure combination task. To clarify the relationship, the mean scores of tasks were tested for subjects who preferred the right and left on each preference item. Some significant differences were found. On some items, the mean scores of subjects with left preferences were inferior to those of subjects with right preferences on the figure-combination task. The result confirmed Levy's finding (1969). But cross-validation on a large sample is required.
