Table 1

Cognitive domains.

Domain	Measures and brief description
Working memory	Digit Span: measure of auditory attention and working memory from the WAIS-III, with both forward and backwards components, dv = forward span, and backwards span scores
Episodic memory	Hopkins Verbal Learning Test-𝑅, Form 1 (HVLT-R): 12 item word list learning task with 20 minute delay; dv = # items recalled after 20′ delay
	Logical Memory Stories II (WMS-III): story memory measure, dv = # units recalled after 30 min delay
Language	Boston Naming Test (BNT): confrontation naming of line drawings of objects/animals; dv = total items correctly named
Executive function	Trail Making Test, Part B (TMT-B): speeded alternating search of letters and numbers (set-shifting), dv = total time
	Stroop Color-Word Test (Golden version): measure of cognitive inhibition of over learned automatic reading response; dv = number items within 45 sec on color-word trial
	Controlled Oral Word Association Test (COWA): a letter fluency task involving production of words beginning with target letters during 60 second trials; dv = number words produced
Processing speed	Stroop Single Word Reading (golden version): timed reading of single words denoting red, green, or blue; dv = number words read in 45′′
	Trail Making Test, Part A (TMT-A): speeded search of letters displayed on a page; dv = total time

Note: WMS-III: Wechsler Memory Scale-Third Edition; WAIS-III: Wechsler Adult Intelligence Scale-Third Edition; dv: dependent variable. References for individual tests are in Lezak et al., (2012) [16].
