Abstract
A model is proposed that describes how people choose multiple-choice answers and deal with subsequent feedback. Central to the model is the construct of likelihood, a signal that: (1) indexes the match between task demands and what is known, (2) gives a basis for decisions, and (3) is estimated by response confidence ratings. In two experiments, subjects answered an item, rated confidence, and studied feedback (for 100 items), and then answered the items again. All predictions of the model were confirmed. Specifically, for right/wrong feedback messages, feedback study intervals were longer after correct than incorrect choices (for correct choices, these intervals decreased as confidence increased). Also, there was no relation between the probability of correcting errors and level of confidence. For feedback messages that consisted of an item with correct alternative marked, there was a positive relation between probability of correcting errors and level of confidence.
