Fig. 7.

A: black dots are the reaction times of the monkey executing a location-scene association task. EM algorithm estimates of the reaction-time curve (solid black curve) and its 95% confidence intervals (gray area) computed from the combined analysis of the reaction-time and binary data. The vertical line marks the IO(0.975) learning trial of 23 for the reaction-time-only analysis. B: EM algorithm cognitive state estimate computed from the combined analysis of the reaction-time and binary data. The gray areas are the 95% confidence intervals. The vertical line marks trial 25, the IO(0.975) learning trial computed using both the reaction-time and the binary data. C: the correct (black squares) and incorrect (gray squares) trial responses are shown at the top of this panel. EM algorithm estimate of the learning curve (solid black curve) and its 95% confidence intervals (gray area) computed from the combined reaction-time and binary data. The vertical line is the IO(0.975) learning trial of 25 for the binary-data-only analysis.
