The role of uncertainty in cognitive change.

Cognitive change was hypothesized to be related to level of S's feeling of uncertainty. Judgments of a photographic stimulus under varying conditions of feedback and quality of stimulus were elicited. The results indicated that change in judgment (cognitive change) is associated with change in level of uncertainty, and the conditions of cognitive change were similar to the Lewinian conceptualization of social change.
