Test measures of the expansion in the eHRB

Tests	Task descriptions	Test measures
Boston Naming Test (BNT)	Task requiring naming 60 visually presented pictures. Semantic and phonemic cues are provided.	BNT = Number of correct answers provided spontaneously or with semantic cues
Thurstone Word Fluency	Task requiring writing down as many words as possible within one minute, first starting with the letter ‘S,’ and then starting with the letter ‘C’ and composed of four letters.	Thurstone Word Fluency = Total number of correct answers within a time limit
Letter Fluency (FAS)	Task requiring saying as many words as possible within one minute starting with the letters F, A, and then S	Letter Fluency (FAS) = Total number of correct answers within a time limit
Category Fluency (Animal)	Task requiring naming as many animals as possible within a minute	Category Fluency (Animal) = Total number of correct answers within a time limit
Paced Auditory Serial Addition Test (PASAT)	Task requiring adding the two most recent digits in a series of audio-recorded digits presented continuously and at increasing speeds	PASAT = Total number of correct answers
Digit Vigilance Test	Task requiring crossing out as rapidly as possible the number 6 in two large digit arrays.	Digit Vigilance (Time) = Completion time Digit Vigilance (Error) = Number of errors
Grooved Pegboard	Task requiring placing 25 pegs into grooves on a metallic board using first the dominant and then the non-dominant hand	Grooved Pegboard (Dominant Hand) = Completion time using the dominant hand Grooved Pegboard (Non-Dominant Hand) = Completion time using the other hand
California Verbal Learning Test (CVLT)	During this task, a wordlist is first presented in five learning trials, each time requiring immediate repetition of as many words as possible. Delayed recall of the wordlist is then assessed twice, after a short and a long delay.	CVLT (Trial 1) = Number of words recalled during the first trial CVLT (Trials 1–5) = Total number of words recalled during trials 1 to 5 CVLT (Short Delay) = Number of words CVLT (Long Delay) = Number of words
Story Memory Test	During this task, a short story is repeated until participants can repeat at least 15 out of 29 pieces of information, with a maximum of 5 allowed trials. Delayed recall is assessed 4 hr later.	Story Memory (Trial 1) = Number of pieces of information repeated after the first trial Story Memory (Learning) = Number of pieces of information learned divided by number of learning trials Story Memory (Delayed Recall) = Number of pieces of information retained
Figure Memory Test	During this task, visual designs are presented on 3 successive cards, with presentations repeated up to 5 times, until participants are able to draw the figures from memory with a 15-point accuracy level. Delayed recall is assessed 4 hr later.	Figure Memory (Trial 1) = Number of pieces of information drawn after the first trial Figure Memory (Learning) = Number of pieces of information learned divided by the number of learning trials Figure Memory (Delayed Recall) = Number of pieces of information retained
Peabody Individual Achievement Test (PIAT)	A series of tasks requiring reading a series of words aloud (i.e., reading recognition), choosing the correct spelling of a word among multiple choices, and choosing among four scenes, the one best depicting a short story previously presented in writing.	PIAT reading recognition = Number of correct answers * PIAT spelling = Number of correct answers * PIAT reading comprehension = Number of correct answers
Boston Diagnostic Aphasia Examination (BDAE) Complex Ideational Material	Task requiring answering twelve read-aloud two-part questions, including commonly known facts and brief stories.	* BDAE complex ideational material = Number of correct answers

Notes: eHRB = expanded Halstead-Reitan Battery. Test measures that are starred in this table were excluded from the factor analysis due to normative samples that were separately recruited or inadequate in size.
