Authors provided normative data for the age-range 18–40 years for the Verbal Judgment Test (VJT), which underpins abstract reasoning on the basis of four subtests:
“Differences”, “Proverbs”, “Absurdities” and “Classifications”. 554 participants (280 males and 274 females) were recruited and the following data were provided: means and standard deviations divided by gender, educational level (8, 13 and 18 years) and age group (18–20 years, 21–25 years, 26–30 years, 31–35 years and 36–40 years) for each subtest and the total score; percentiles for each subtest, divided by age group, and, when appropriate, educational level and/or gender; Rho correlations between age group, gender, educational level, intelligence and VJT scores.
Results showed that age and education positively affected performance in the subtests of Differences, Proverbs and Classifications, which are mostly based on previous knowledge, experience, and crystallized intelligence, but did not affect performance in the Absurdities subtest, which encompasses to some extent fluid intelligence.
