Personal tempo, personality, cognitive speed and cognitive performance

One hundred young males filled in an untimed personality questionnaire. The time needed was taken to be the subjects' personal tempo. They also worked twice on a timed substitution test; their score on this test was taken to be their cognitive speed. It was hypothesized that personal tempo was related to personality and cognitive speed to performance on cognitive tests. The results confirmed the hypothesis. Those whose personal tempo was faster had higher Extraversion and lower Neuroticism and Lie-scores. Those whose cognitive speed was faster, however, did better on four out of five cognitive tests and had a higher Lie-score. It seems that the two speed factors, as hypothesized by Spearman, are indeed two separate and distinct factors, each correlated with different variables: cognitive and personality.
