Figure 11

In the top panel, two z-ROC functions for responses preceded by an “old” response or a “new” response. The bottom panels show how the model accounts for this. For the confidence categories, “−−−” is high-confidence new, “+++” is high-confidence old, and the other symbols represent lower confidence responses. ZHit = hit rate z-score; ZFA = false-alarm rate z-score.
