Relative effect of father's education and "psychoticism" on some measures of aptitude in Iran.

This paper compares differences in mean test scores of contrasting groups formed in terms of parental education and psychoticism. Subjects were 747 male and 239 female Iranian university applicants. Psychoticism was measured by a Persian adaptation of Eysenck's test. Mean differences between groups with very high and very low psychoticism scores on tests of general intelligence and Persian language are larger than those between groups with college-educated versus illiterate or semiliterate fathers. The reverse is found on a test of English language.
