This study investigated implicit self-control dispositions—implicit approach tendencies towards low-caloric food rather than towards high-caloric food—in dieters. Action tendencies were assessed and trained using the Approach-Avoidance Task (AAT). Additionally, positive/negative affective associations [Brief Implicit Association Test (BIAT)], approach/avoidance associations (BIAT), and attentional biases [Dot Probe Task (DPT)] were assessed before and after training. Before training, dieters showed a more negative affective association with high-caloric food than non-dieters (positive/negative BIAT), consistent with the presence of self-control dispositions. On the AAT, all participants, not just dieters, showed more approach of low-caloric food than of high-caloric food. Results of neither the approach/avoidance BIAT nor the DPT showed any indication of implicit self-control dispositions. This study also investigated whether implicit self-control dispositions interfered with AAT training effects. This did not seem to be the case, as action tendencies could be strengthened even further. Moreover, training effects generalized to the DPT.
