BACKGROUND: Children of depressed mothers are themselves at elevated risk for developing a depressive disorder. We have little understanding, however, of the specific factors that contribute to this increased risk. This study investigated whether never-disordered daughters whose mothers have experienced recurrent episodes of depression during their daughters' lifetime differ from never-disordered daughters of never-disordered mothers in their processing of facial expressions of emotion. METHOD: Following a negative mood induction, daughters completed an emotion identification task in which they watched faces slowly change from a neutral to a full-intensity happy, sad, or angry expression. We assessed both the intensity that was required to accurately identify the emotion being expressed and errors in emotion identification. RESULTS: Daughters of depressed mothers required greater intensity than did daughters of control mothers to accurately identify sad facial expressions; they also made significantly more errors identifying angry expressions. CONCLUSION: Cognitive biases may increase vulnerability for the onset of disorders and should be considered in early intervention and prevention efforts.
