In four experiments mood was measured before and after complaining or affirmation. Participants complained or affirmed either themselves or listened to such communications of another person. Mood decreased after complaining and increased after affirmation - a 'saying is experiencing' (SIE) effect. This effect was found also in the cognitive load condition suggesting that automatic mood contagion underlies the SIE effect rather than mechanisms based on self-perception or self-awareness. Appropriateness of a topic for complaining appeared a boundary condition of the SIE effect: When a topic was considered by participants the most appropriate for complaining, the act of showing dissatisfaction with the topic led to mood improvement.
