Based on the statistical decomposition of the variance in the Raven’s Advanced Progressive Matrices (APM), the present study attempted to examine whether impulsivity relates to a purified measure of intelligence or is more related to systematic method variance associated with the item-position effect in the measurement of intelligence. A sample of 232 undergraduates was administered the APM, the UPPS-P Impulsive Behavior Scale, and the Barratt Impulsiveness Scale-11 (BIS-11). The results showed that impulsivity, measured by either the UPPS-P or the BIS-11, was significantly related only to the position-specific component of the APM. These results suggest that the relationship between impulsivity and intelligence is a spurious relationship due to the use of similar items in the assessment of intelligence.

Many studies have shown that impulsivity is negatively and significantly related to performance on intelligence tests (Lozano et al., 2014, Russo et al., 2008 and Schweizer, 2002). However, the question arises whether impulsivity is truly related to intelligence or only prevents individuals from performing on intelligence tests according to their true intelligence. In order to address this issue, it should not be overlooked that scores on intelligence tests not only reflect intelligence, but also method variance that may distort the estimation of the relationship between theoretical constructs (Carlstedt et al., 2000 and Kubinger et al., 1991).
