  1. Values are means ± standard deviations. Word, Color, and Word-Color counts were analyzed by MANOVA. MANOVA analysis revealed overall Wilks’ Lambda group (p = 0.83), time (p < 0.001), and group x time (p = 0.17). Greenhouse-Geisser time and group x time (G x T) interaction p-values are reported with univariate group p-values. q represents quadratic effect and l represents linear p-value from univariate ANOVA. * represents p < 0.05 difference from baseline. ^ represents p < 0.05 difference from wk 4. arepresents p < 0.05 from PLA. brepresents p < 0.05 from PWS. crepresents p < 0.05 from PWS + S
