This study examined the relationships between extraversion, neuroticism, and non-verbal intelligence in a combined group of 159 West Indian college and university students of both sexes. The only significant correlation was that between extraversion and neuroticism, (p <.05), which is negative.
Partial correlation coefficients were low and negative. The F test for testing departure from linearity of the relationships between each of the personality dimensions, extraversion and neuroticism, and non-verbal intelligence did not reach statistical significance. The overall results do not support significant personality-intelligence relations, positive or negative, nor do they support significant curvilinearity of these relations. Furthermore, the results do not fully confirm the findings of an earlier study done elsewhere.
