marginally significantp = 0.06
Using Pillai’s trace, the multivariate statistics revealed a main effect of WTC on cognitive functioning, F (3,31) = 3.32, p = 0.03, η 2 = 0.24, as well as a marginally significant interaction between WTC and leisure time activity, F (3,31) = 2.79, p = 0.06, η 2 = 0.21, but no main effect of leisure-time activity, F (3,31) = 1.48, p = 0.24, η 2 = 0.13, and voluntariness in WTC, F (3,31) = 2.03, p = 0.13, η 2 = 0.16.
