This study tested the validity of the depressive realism versus the negativity hypotheses by investigating the relation between confidence and accuracy in clinically depressed, dysphoric and control participants when performing decision tasks. In Experiment 1, depressed and dysphoric recovered depressed patients showed systematic PTPE underconfidence across several tasks regardless of performance accuracy but displayed item-by-item overconfidence equivalent to that of controls on tests of general knowledge and object recognition. In Experiment 2, control participants demonstrated both item-by-item overconfidence and PTPE underconfidence on a newly developed self-relevant adjective recognition task, thus enabling a stronger contrasting test of the two hypotheses in subsequent experiments.
