Information processing in everyday life: emotion-congruent bias in mothers' reports of parent-child interactions.

The authors examined the role of emotions in mothers' perceptions of the parent-child relationship. Ninety-nine mothers completed a measure of trait affect and then interacted with their preschool children under low- and high-stress conditions. After each interaction session, mothers rated their mood states and positive and negative aspects of parent-child behavior. To control for differences in the quality of dyadic interaction, observers also rated behavior. Across sessions, mood was a more robust predictor of mothers' perceptions than was trait affect. When trait effects did occur, they were mediated by mood states. Results suggest that when emotionally congruent information processing occurs in real-life situations, emotions generated by the interactions play a preeminent role in the immediate interpretation of the exchange.
