SD: standard deviation; SMT: Simple Choice Movement Time (milliseconds); SRT: Simple Choice Reaction Time (milliseconds); CMT: Five Choice Movement Time (milliseconds); CRT: Five Choice Reaction Time (milliseconds); DSST: Digit Symbol Substitution Task (# of filled boxes correct); FTT: Finger Tapping Task (mean # of taps); Trails A (seconds);
Normative standards for Movement and Reaction Time values are presented as Z scores relative to the normative mean
