Competition Effects in Visual Cortex Between Emotional Distractors and a Primary Task in Remitted Depression.

ABSTRACT:

Background

Attentional biases, particularly difficulty inhibiting attention to negative stimuli, are implicated in risk for major depressive disorder (MDD). The current study examined a neural measure of attentional bias using a continuous index of visuocortical engagement (steady-state visual evoked potentials [SSVEPs]) before and after a negative mood induction in a population at high-risk for MDD recurrence due to a recently remitted MDD (rMDD) episode. Additionally, we examined working memory (WM) capacity as a potential moderator of the link between rMDD and visuocortical responses.

Methods

Our sample consisted of 27 women with rMDD and 28 never-depressed women. To assess attentional inhibition to emotional stimuli, we measured frequency-tagged SSVEPs evoked from spatia
