Behaviorists accept, but go beyond, Williams' notion that there is an evolutionary origin to some unlearned pain behaviors. A behavior-analytic developmental model is a better fit for explaining the totality of pain behaviors. This model focuses on respondent-operant interactions and views much pain behavior as “mands” (i.e., demands). Behaviorally based explanations from the crying and social referencing literature support this model.
