  1. Values are means ± standard deviations for Stroop Word, Color, and Word-Color tests. MANOVA analysis revealed overall Wilks’ Lambda treatment (p < 0.001), time (p < 0.001), and treatment x time (p < 0.001). Greenhouse-Geisser univariate p-levels of interaction (treatment x time) are reported above. * represents p < 0.05 difference from baseline. a denotes a significant difference from PLA. b denotes a significant difference from PWS. c denotes a significant difference from PWS + S
