Description of neurobehavioral tests and functions for BARS

Test Description	Function	Variables
Finger tapping (TAP) Right and left hand taps for 20 seconds; 2 trials/hand	Response speed and coordination	Average number of taps each hand*
Divided attention (DAT) Tap while reciting nursery rhyme (Chang song)	Divided attention	Average number of taps each hand while singing*
Purdue pegboard (PEG) Number of small pegs placed in holes during two 30 second trials each hand Preferred, non-preferred, and both hand trials	Dexterity	Average number of pegs placed: preferred, non-preferred, both*
Visual motor integration (VMI) Copied line drawing	Hand-Eye coordination	Total score for correct segments*
Digit span (DST) •Spoken presentation of number sequences ◦Forward and reverse recall	Memory and attention	raw score forward, backward, total*
Object memory test (OMT) Show and name 16 objects Immediate and delayed recall Recognition of target and non-target items	Recall and recognition memory	Immediate recall; delayed recall; recognition*
Symbol-Digit (SDT) ◦Match number and symbol from key	Information processing speed	Average latency (ms) of response for correct match#
Match-to-Sample (MTS) •15 stimuli shown for 3 seconds •Identify target from 3 choices ◦Delay between presentation and choice varies from 1 to 8 seconds	Visual memory	Average latency (ms) for correct choice# Number correct*
Continuous performance (CPT) Different shapes shown rapidly for 4 min in original version and 7 min in alternate version Press key when target (original = circle; alternate = triangle) shown	Sustained attention	Percent correct* Average latency (ms) for correct response (hit)# Average latency (ms) for false alarms# D-Prime*
