Characterizing the Impact of Category Uncertainty on Human Auditory Categorization Behavior
Figure 6
Predictions of the Bayesian model with different categorization behaviors.
(a) Predicted psychometric functions for the model with objective priors during each of the three prior-probability conditions. The predictions assuming probability-matching (MATCH) behavior are on the left, whereas those of the MAP decision strategy are on the right. (b) Predicted psychometric functions for the model with subjective priors. Example predictions are plotted for three selected values of for MATCH (left) and MAP (right). Line colors distinguish MAP versus MATCH and color shade denotes the three prior probabilities. For all model predictions,
was fixed to the mean discrimination threshold across all subjects.
