Abstract : The development and use of schemata in decision making is examined. Subjects are trained to evaluate alternatives by calculating expected outcomes. In subsequent tests, subjects are required to select the best alternative without being given enough time to compute outcomes. Under these conditions subjects adopted a hybrid decision strategy employing both schemata and approximations to outcome calculation. The schemata were organized around a prototype. They specify a judgement associated with the prototype and also contain feature oriented data useful for accommodating differences between observed situations and the situation prototype. There was no evidence for other memory reference structures examined. These included indicator/counterindicator features and wholistic schemata that could entirely replace the learned outcome calculation procedure. There was also no support for memory structures that define discriminator boundaries between different types of judgements or decisions.
