follow-up, t (9) = 2.355, p < 0.05, d = 0.78 (see Table 3 ).There was a marginally significant main effect of Session for coefficient of variation of SART response times at baseline vs. follow-up, F (1,15) = 4.279, p < .06, η p 2 = 0.222 , that was accounted for by the GMT group, t (9) = 2.410, p < 0.04, d = 0.993 (see Table 3 ; Figure 1 , top right).
