Abstract	Previous studies failed to find evidence for rational action selection in children under 2 years of age. The current study investigated whether younger children required more training to encode the relevant causal relationships. Children between 1 1/2 and 3 years of age were trained over two sessions to perform actions on a touch-sensitive screen to obtain video clips as outcomes. Subsequently, a visual habituation procedure was employed to devalue one of the training outcomes. As in previous studies, 2- and 3-year-olds chose actions associated with an expected valued outcome significantly more often during a subsequent choice test. Moreover, analysis of children's first responses in the post-devaluation test revealed evidence of rational action selection even in the youngest age group (18-23 months). Consistent with dual-process accounts of action control, the findings support the view that the ability to make rational action choices develops gradually. (Contains 3 figures and 2 tables.)
