Figure 7. Higher Learning Rate and Lower Sensitivity to Difference in Subjective Reward Values in Reversal Compared to Discrimination Learning.
Note. (A and B) Learning parameters and sensitivity to difference in reward values for the single-learning rate model during the discrimination (A) and reversal (B) phases. We find no significant difference in parameter values between reward probability groups during discrimination or reversal. However, we do find significantly higher learning rates and significantly lower sensitivity to difference in reward values parameters following reversal.
