Abstract

There has been an increase in the ethnic/cultural diversity in the word. For example, in the United States in the twentieth century the Hispanic population has more than doubled since 1980, and since 1990 the population of non-white and non-black races has increased from 7.7% of the population to 12.5%. Such diversity has lead some to claim that traditional tests of cognitive ability do not provide an accurate assessment because of their heavy reliance on language. Therefore the use of nonverbal measures of intelligence has become increasingly important and prevalent.

This study is one of few studies done to date on the validity of the CTONI-2's scores, despite is being published for over 6 years. The results showed that the subtest scores appear to be one-dimensional and that the subtests appear to measure a single construct that is related to other measures of intelligence, moderately related to measures of academic achievement, and minimally related to measures of personality. Nonetheless, caution should be used in interpreting the scores, especially with high-ability adults, as the majority of the test's items appear to be most appropriate for respondents with average or lower cognitive ability
