A sample population of 139 fifth grade students, ranging in age from nine years to twelve years eleven months, was drawn from a data pool created from test results collected from four elementary schools in a south central Kentucky municipality. Tests used in the study were the Wechsler Intelligence Scale for Children – Revised (WISC-R) and Cattell’s Children’s Personality Questionnaire (CPQ).

These data were examined to determine the relationship of extraversion to performance on a standardized intelligence test.

Correlations for the experimental variables and extraversion ranged from .12 to .51.

The results indicated that extraverts had higher Performance, Verbal and Full-Scale I.Q.’s. No significant differences were found on extraversion scores for males vs. females.

Overall the general hypothesis that extraversion was positively correlated to performance on the WISC-R was supported by the data.
