For AVG, Cz, and LM modes, the lifetime MDD by condition interaction again emerged (AVG F(2, 603) = 10.5; Cz F(2, 603) = 12.0; LM F(2, 603) = 8.3; all p < .001), indicating that the withdrawal condition, but not the approach condition, differentiated lifetime MDD+ and MDD− groups more robustly than the rest condition (see Figure 5). Specifically, the lifetime MDD+ group displayed relatively less left frontal activity than the lifetime MDD− group during the withdrawal condition (AVG: p < .001 and d = .48; Cz: p < .001 and d = .56; LM: p < .001 and d = .49) but not the rest condition for LM (p > .15). Although the groups differed during the rest condition for AVG (p < .05 and d = .25) and Cz (p < .05 and d = .24), the pattern of means was again in the unpredicted direction, with the lifetime MDD+ group exhibiting higher relative left frontal activity than the lifetime MDD− group. The approach condition, although replicating the pattern of means evident in the main results (wherein the
