In 2 experiments, we tested the prediction that perceptions of sarcasm are influenced critically by 2 factors: the size of the situational disparity between speakers' beliefs, desires, or expectations and actual outcomes; and the memory cues presented by the ironic utterance that directs perceivers' attention to the situational disparity. Experiment 1 verified the prediction that the perception of sarcasm increases with an increase in the size of situational disparity. Experiment 2 investigated the relation between situational disparity and another cue to speakers' sarcastic intentions, echoic mention. The experiment found additive effects of the magnitude of situational disparity and the memory cueing capability of the utterance, suggesting that the factors make independent contributions to the perception of sarcasm.
