AP, Adjusted Number of Pumps on BART (Lejuez et al., 2002); P, Total Points on BART; E, Number of Explosions on BART; WMS-III, Wechsler Memory Scale—Third Edition (Wechsler, 1997); NAART35, Short Version of North American Adult Reading Test (Uttl, 2002).

^aInitial risk perception is calculated such that higher values denote lower initial risk perception.

^bGender was encoded as female = 1, male = 0.

^cNAART Vocabulary is scored such that higher scores are related to poorer performance. For all other neuropsychological tests, higher scores indicate better performance.

^†p < 0.10,

^*p < 0.05.
