SOCIAL ROLES AND UTILITIES IN REASONING WITH DEONTIC CONDITIONALS

A set of experiments is reported in which a new formulation of deontic thinking is tested. This is that people represent subjective utilities inherent in conforming to or violating deontic statements, along with the social dynamics of these statements. The experiments used Wason's selection task and tested people's understanding of conditional permission. In the first two experiments, familiar scenarios referring to family interactions were used. In the third, an imaginary business content was used. In both cases it was apparent that people's thinking depended on their representation of the utilities associated with the agent of a permission statement (the party who lays down the rule) and the actor (the party whose behaviour is its target). The results are discussed as favouring an explanation in terms of mental models, rather than the schema theories which have dominated this field hitherto. © 1991.
