Abstract

This study examines explicit memory bias for emotional information in children and adolescents with major depressive disorder (MDD). Participants were a convenient sample of 28 children and adolescents of mothers with MDD, 28 children and adolescents with MDD, and 29 healthy controls. Their age range was 11-17 years old. The groups were matched for gender ratio, mean age, and the years of educational level. They were assessed by the Recall Task. Emotional stimuli consisted of three sets of words namely sad, happy, and neutral words. Children and adolescents of mothers with MDD similar to children and adolescents with MDD recalled more sadness stimuli in comparison with the controls. In other words, they showed an explicit memory bias towards sad stimuli. Also, healthy children significantly recalled more happy words than the other two groups. There was no significant difference among the three groups for the recall of neutral stimuli. Current findings support that there is a recall memory bias for emotional information in children with MDD. These children more than healthy children recall sad words. Moreover, healthy children recall happy words more than children with MDD.
