Letter Number Sequencing from the Wechsler Adult Intelligence Scale – 4th edition, Spatial span from the Wechsler Memory Scale – 3rd edition. CWIT, Color-Word Interference Test; TMT, Trail Making Test, these and the Tower all from the Delis-Kaplan Executive Function System. P-values estimated using Satterthwaite’s method.
*p 0.05 after application of control for false discovery rates.
§Hypothesized increase in scores from pre-assessment, remaining measures are hypothesized to decrease.
