Matrix reasoning	52.5 (± 1.8) (n = 13)	50.9 (± 1.1)	0.44
Vocabulary	48.9 (± 2.9)	44.0 (±2.3) (n = 20)	0.19
CVLT-II
Short term recall	42.1 (± 3.1)	44.5 (± 1.6)	0.47
Short-delay free recall	45.4 (± 2.6)	48.1 (±2.3)	0.45
Long-delay free recall	45.0 (38.8–51.3)	50.0 (35.0–50.0)	0.93
D-KEFS CWIT
Inhibition completion time	45.8 (± 2.7) (n = 13)	42.1 (±2.3) (n = 20)	0.31
Inhibition/switching completion time	47.0 (43.0–49.3) (n = 12)	43.0 (30.0–50.0) (n = 17)	0.41

Mean and standard errors with t-test p values and median and interquartile range with Wilcoxon rank sum test p values are presented for parametric and non-parametric values, respectively
