Means (medians) ± standard deviations for the group demographics for participants with aphasia (PWA) and control participants and the Western Aphasia Battery–Revised Aphasia Quotient (WAB-R AQ) and subtest scaled scores.

Variable	PWA	Control
n	30	18
Age	62 (64) ± 10	63 ± 9
Gender (female)	3	10
Education in year	15 ± 3	16 ± 4
Months postonset	41 (26) ± 40
Lesion volume (cm3 )	93 (64) ± 74
AOS severity	3 (2) ± 2
PALPA Word Minimal Pairs	0.8 ± 0.2
WAB-R AQ	66.8 (71.6) ± 25
Spontaneous Speech	12.8 (14) ± 5
Content	7 (8) ± 3
Fluency	5.8 (5) ± 3
Auditory Comprehension	8.3 (9) ± 2
Repetition	6.4 (7) ± 3
Naming and Word Finding	7.1 (8) ± 3

Note. The groups did not differ significantly for age, U = 225.5, p = .84, or education, U = 285.5, p = .22. There were more females in the control group than in the PWA group, χ²(1, N = 48) = 10, p = .002. AOS = apraxia of speech; PALPA Word Minimal Pairs = Psycholinguistic Assessments of Language Processing in Aphasia Same–Different Discrimination Using Word Minimal Pairs subtest.
