The results of the study are consistent with self-perception theory, which proposes that people infer their attitudes and emotions from their behavior. In this study, the participants who made a pained expression when they saw the shocks being delivered inferred that they must have felt more distressed or anxious than those who did not make such an expression. This inference was supported by the physiological measures of increased perspiration and faster heart rates.
