Objectives. This study (N= 139) explored whether two measures that capture non-reflective processing (viz. a self-report measure of impulsivity and a behavioural measure of implicit self-control) would contribute to the prediction of dietary behaviour over and above cognitive predictors specified by the theory of planned behaviour (TPB). Methods. Four dimensions of impulsivity were measured at Time 1. Implicit self-control was measured at Time 2, alongside TPB predictors relating to the avoidance of high-calorie snacks. At Time 3, participants reported their snacking behaviour over the previous 2 weeks. Results. Results revealed that both impulsivity and implicit self-control significantly contributed to the prediction of snacking behaviour over and above the TPB predictors. Conclusions. It was concluded that the predictive utility of models such as the TPB might be augmented by the inclusion of variables that capture non-reflective information processing
