the Nelson Adult Reading Test (AMNART), as an estimate of premorbid IQ (Grober et al., 1991). The following 9 domains, and their component tests, were included in the final analyses for neuropsychological performance: (1) Attention (Stroop Color, MC Numbers Forward, MC Numbers Reversed, MC Alphabet, MC Word List 1), (2) Verbal Processing (COWAT), (3) Abstraction/Cognitive Flexibility (Short Categories, Stroop interference score, Trail Making Test B, MC Analogies, MC Object Match A), (4) Psychomotor (Trails A, Symbol Digit), (5) Immediate Memory (MC Story immediate recall, Rey immediate recall, MC Word List 2), (6) Delayed Memory (MC Story delayed recall, Rey delayed recall), (7) Reaction Time (MC Timers simple and cued), (8) Spatial Processing (MC Tic Tac, MC Clocks, Block Design), and (9) Auditory Working Memory (PASAT at delays of 2.4, 2.0, 1.6, and 1.2 seconds). Normative scores derived from a nationally representative sample of adults are available for each test, either from the creators or distributors of the tests.
