From: Love withdrawal predicts electrocortical responses to emotional faces with performance feedback: a follow-up and extension

Figure 2

Grandaverage ERPs at Cz, averaged across electrodes 31, 53, 54, 55 (CPz), 61, 62 (Pz), 78, 79, 80, 86, and Cz, illustrating the LPP. A: ERPs to feedback stimuli, averaged across all four categories and across tasks, for participants reporting high and low love withdrawal. Participants were divided into groups for displaying purposes only. B: Scalp voltage distribution of the color effect on LPP amplitude (green-red). C: ERPs to green (correct) and red (error) feedback stimuli recorded during the flanker task. D: ERPs to green (correct) and red (error) feedback stimuli recorded during the time-estimation task. Participants reporting higher maternal use of love withdrawal showed a less positive response to the feedback stimuli between 400 and 800 ms after stimulus onset (LPP), F(1,17) = 4.65, p < .05, η2 = .22. More positive amplitudes were observed during the time-estimation compared to the flanker task, F(1,17) = 21.60, p < .01, η2 = .56, and in response to green compared to red stimuli, F(1,17) = 8.85, p < .01, η2 = .34. ERPs were low-pass filtered at 15 Hz for displaying purposes only. The time-window used for analyses of LPP amplitudes is marked with a rectangle.
