title: Choice and goal-directed behavior in preschool children.
abstract: Preschool children (3-4 years old) were trained to perform two actions to gain different outcomes, in the form of video clips from different cartoons, before one of these outcomes was devalued by noncontingent exposure. The effect of outcome devaluation was subsequently assessed in an extinction test by giving children the opportunity to perform both actions in the absence of any outcomes. When the two actions were trained concurrently, performance during the test was modulated by outcome value and children showed a preference for the action trained with the currently valued outcome. By contrast, when each action was trained separately on different trials, test performance was insensitive to outcome devaluation. These effects of the training schedules are interpreted in terms of dual-process theories of action control.
