Note: Gender was dummy coded with female as −1 and male as 1. Trails A and Digit Symbol Substitution measured processing speed; Trails B measured executive control; Animal Fluency measured verbal fluency; Shipley Vocabulary corresponded to the Shipley Institute of Living Scale which measured crystallized intelligence. Trails A and B were timed measures, meaning that lower scores corresponded to better (faster) performance. For all other cognitive measures, higher scores indicated better performance. Personality variables (Agreeableness, Conscientiousness, Emotional Stability, Extraversion, Openness to Experience), Total System Use, and Age (years) were coded such that higher values corresponded to greater quantity. Bolding indicates statistical significance (P < .05).
