Flexible use of source information: Processing components of the inconsistency effect in person memory

The impact of social expectancies on person memory is investigated in two experiments using a source-recognition paradigm. Multinomial model analyses disentangled effects on item-memory, source-memory, and heuristic reconstructive guessing processes. Cognitive load and retention interval were manipulated. In two pilot studies and Experiment 1, participants were presented equal numbers of consistent and inconsistent statements about two stereotyped targets. Source-memory showed an inconsistency effect that is restricted to conditions with load at encoding and longer retention interval. Consistency biases in reconstructive guessing of statement-person associations emerged under load. Item-memory exhibited only a small inconsistency effect in conditions without load and short retention interval. Experiment 2 yielded similar results, although expectancies were induced on-line via the distribution of positive and negative behaviors across non-stereotyped targets. Findings support a model of flexible use of source information, demonstrate the importance of source memory, and of assessing it separately from item recognition and reconstructive guessing.
