Test	Function assessed	Units
Continuous performancea	Sustained attention	m/s
Digit-symbola	Visual scanning and processing	seconds
Finger tapping, dominant hand	Motor speed	avg # of taps (4, 10-second trials)
Grooved pegboard, dominant handa	Fine motor coordination	seconds
Auditory verbal learning total recall	Verbal learning and memory	# correct (0-36)
Auditory verbal learning delayed recall	Memory	# correct (0-12)
Auditory verbal learning recognition	Memory	true positives - false positives (−12−12)
Sequences A latencya	Motor speed and scanning	seconds
Sequences B latencya	Motor speed and scanning	seconds

^aHigher score indicate poorer performance.
