Schema congruence and depression: loss of objectivity in self- and other-inferences

Depressed and nondepressed students judged the plausibility of positive and negative inferences ostensibly made either by themselves or by others. Negative self-inferences were judged by depressed students as more plausible, and positive other-inferences as less plausible. The results were in accord with Beck's (1967) theory of schema-based distortion in depression, which proposes that persons vulnerable to the development of depression are prone to make erroneous negative inferences and to then regard those inferences as plausible and correct. The results also suggested that depressed persons responded differentially depending on whether they were instructed to consider the inferences as their own or another's, whereas nondepressed persons did not.
