Influential models of both category learning (concepts with discrete predicted variables) and function learning (respectively continuous; which we study here), only model predictions and thus cannot easily account for confidence judgements (Hoffmann, von Helversen, & Rieskamp, 2016;Mc-Daniel & Busemeyer, 2005).
