Figure 5.

Comparing Experiments 2 and 3 testing phase responses. Participants in Experiment 3 did not complete initial supervised trials. Therefore, they tended to start from a default category boundary that was much lower in anger as compared to the 50% boundary taught to participants in Experiment 2 in the supervised learning phase. Despite this main effect of removing the supervised trials (illustrated by the dashed Experiment 3 lines being further to the left), Experiment 3 participants nonetheless learned distinct category boundaries for each of the three actors.
