| Sumario: | Subjective confidence reports are used in numerous research paradigms to examine the extent to which participants are aware of their performance in a task. By examining the discrepancy between objective performance and subjective confidence ratings, inferences can be made about the conditions in which participants have greater explicit knowledge of the representations and processes used to complete a task. In the current study, we examined the effects of prior knowledge on subjective assessments of performance using a categorisation task wherein lists of features that defined exemplars shared latent feature associations on the basis of prior knowledge or had no prior associations. Using 2 methods for computing confidence, we demonstrate the strengths and limitations of these measures of subjective awareness. Whereas our findings replicated the effect of prior knowledge on learning, our results challenge the role of explicit and implicit knowledge suggested by previous research using a similar paradigm.
