The relationship between demographic variables and NART performance in normal subjects.
British Journal of Clinical Psychology, 27(2) pp. 181–182.
The relationship between NART performance and demographic variables was examined in a group of subjects free of neurologic or psychiatric disorder (n = 201). NART estimated IQ was significantly correlated with education, social class and age. The correlation between age and NART IQ was no longer significant after partialling out either education or social class. There was no evidence of a curvilinear relationship between age and NART performance. There was no significant sex difference in NART performance. Nelson's (1982) report of a high split-half reliability was confirmed.
