Procedure Participants took part one at a time. They were invited into a quiet room, and asked to take place in front of a computer. Participants were told that they would see 50 speakers in different emotional states, and that their task was to rate the perceived state on a 7 point valence scale ranging from 1 (= very negative) to 7 (= very positive). Participants were not informed about the fact that some of the speakers were expressing incongruent emotions. The stimuli were offered in one of two random orders, to compensate for potential learning effect. They were preceded by a number displayed on the screen indicating which stimulus would come up next, and followed by a 3 s interval during which participants could fill in their score on an answer form. Stimuli were shown only once. The experiment was preceded by a short training session consisting of three speakers (for which a different sentence was used) to make participants acquainted with the stimuli and task. If all was clear, the actual experiment started, after which there was no further interaction between participant and experimenter. The entire experiment lasted approximately 10 min.
