Objective: Driving is a complex task that requires a seamless interaction of motor and cognitive abilities. This study looks at the relationship between WAIS-IV IQ Indices to performance using a driving simulator. Method: Participants included 92 males and 109 females, with an average age of 29.42 years (SD = 12.45), average Full Scale IQ of 113.88 (SD= 11.69), and average education of 15.42 years (SD = 2.13). Participants with a history of neurological and psychological problems were excluded. Results: Pearson's correlations were conducted to identify the relationship between various indices on the WAIS-IV (i.e., Verbal Comprehension, Perceptual Reasoning, Processing Speed, Working Memory) and the total number of collisions, tickets, and adverse driving events as indicated by a driving simulator. Analyses revealed significant indirect relationships at the alpha = .01 level between VCI and total tickets (r = −.193), PSI and total tickets (r = −.198), and PSI and total adverse events (r = −.213). No significant relationships were found between the WMI and PRI and the aforementioned variables. Conclussion: These results suggest that higher scores on WAIS-IV indices of Verbal Comprehension and Processing Speed are associated with lower levels of tickets received and adverse events on a driving simulator. The data indicated that processing speed deficits is associated with an increase in driving collisions presumably because of slow reaction and decision-making . The results imply that individuals who exhibit stronger verbal skills and faster processing speed are less likely to engage in risky driving behaviors because they exert stronger cognitive control. Future studies should examine this association in a sample of lower cognitive ability.
