Altering the balance of recollection and familiarity influences the revelation effect

The revelation effect occurs when recognition test probes are more likely t o be called "old" if they are preceded by a verbal processing task. Two exp eriments examined the role of familiarity and recollection in producing thi s effect. Each experiment tested the hypothesis that decreasing recollectio n would heighten the magnitude of the revelation effect. In Experiment 1, t he revelation effect increased by delaying the recognition Lest. In Experim ent 2, the revelation effect increased when the presentation rate of the st udy words was reduced. These results are discussed in terms of the variable s that produce the revelation effect in episodic and nonepisodic memory jud gments.
