THE RELATIONSHIP BETWEEN INTELLIGENCE, PERSONALITY AND INSPECTION TIME

This study investigates the relationship between intelligence test per formance, a test of visual inspection time (IT) and personality and te mperament dimensions. Howe's (1990) hypothesis that IT and IQ are empi rically related because of personality or temperament variables is eva luated and rejected. IT and performance IQ (PIQ) were significantly re lated independent of personality or temperament variables. IT and verb al IQ (VIQ) mere unrelated. Robinson's (1989) hypothesis that ambivert s (moderate extraversion) perform significantly better on IQ tests was examined and supported. Ambiverts performed significantly better on v erbal and performance measures of the Wechsler Adult Intelligence Scal e-Revised (WAIS-R) and on the Raven's Advance Progressive Matrices (AP M). Mobility from the Strelau Temperament Inventory (STI) was also rel ated to performance IQ (PIQ) and Raven's test scores. These results su ggest an important role for the concepts of arousal and/or arousabilit y in a biological model of intelligence. Implications for intelligence assessment are discussed.
