Altered Working Memory Processing of Emotion in Adolescents with Dysphoric Symptomatology: An Eye Tracking Study.

It has been suggested that altered processing of emotion during cognitive control plays an important role in the etiology of depressive symptoms. The current study investigates the influence of emotional stimuli on working memory (WM) in adolescents with dysphoric symptomatology (DS). Twenty-five adolescents with DS and 40 adolescents with no dysphoric symptomatology (NDS) completed a memory-guided eye movement task. This task assessed the influence of irrelevant affective information on WM processes during high and low cognitive load. Latency analyses showed that, in the high load WM condition, negative distractors disturbed WM performance in adolescents with NDS, but not in adolescents with DS. Accuracy analyses revealed that adolescents with NDS had higher accuracy rates in the presence of positive distractors relative to negative and neutral distractors, and in comparison to adolescents with DS. The findings indicated altered WM performance in the context of emotional distractors in adolescents with DS and may contribute to theoretical knowledge and early prevention of youth depression.
