Abstrakt: In a family study of eight spatial ability tests the question was asked whether the number of years of schooling of the parents influenced the degree of parent-offspring resemblance on these tests, with special reference to the facets of rule-task and presence/absence of rotation. Positive correlations were found between the years of schooling of the parents and their performance. The correlations were higher for rule-inference tests than for tests of rule application. Holding constant the parents' education reduced the correlations between parents' and children's scores on the tests. However, not all tests were equally affected. The largest changes were again in the rule-inference tests, while the Shepard-Metzler rotation test appeared least affected. The data show a pronounced effect of education on analytical ability and indicate that parent-offspring correlations of such tests should be viewed with caution.
