Many experiments in cognitive psychology and other domains ask for confidence ratings (e.g., on a 0-100 scale, 100 meaning "I'm sure I experienced this stimulus"). What accounts describe how these decisions are made?

Review papers of this issue would be particularly helpful.

Maybe look at the question about forced decisions, and my answer about evidence accumulation: . I guess, but do not know, that confidence is an estimate of how quickly you accumulated evidence for one of the decisions, and how much evidence there is for the other. The process is subconscious though, so how one would make the result conscious and verbalize this, I don't know. Perhaps an actual estimate of how quickly you knew. – Robin Kramer Apr 22 at 19:15
Have a look at this recent Neuron article, it's not a review but might give you a good -though not simple- starting point – elisa Apr 24 at 14:53
