Method
Participants
Ninety undergraduate students at the University of California Santa Barbara were recruited to participate in Experiment 2. Thirty participants were trained with the 1D-Width category structure (Fig. 1, top left), 30 participants were trained with the information-integration category structure (Fig. 1, bottom left) and the remaining 30 participants were trained with the conjunction rule (Fig. 1,bottom right). Each participant was given credit for participation as partial course requirement. None of the participants took part in Experiment 1.
