We propose that the benefits of directed forgetting are explained by the differences in recall arising from individual strategy choices used to encode List 2. In Experiment 1, inducing participants to encode both lists using the same strategy (either shallow or deep) led to significant costs of directed forgetting but abolished the benefits. In Experiment 2, inducing a shallow encoding on List 1 and a deep encoding on List 2 produced similar results, abolishing the benefits but not the costs. Reanalysis of Sahakyan and Kelley's (in press) Experiment 2 showed that the costs of directed forgetting could be detected irrespective of participants' strategy choices. However, the benefits of directed forgetting are best explained by a more frequent use of deeper encoding of the second list by the forget group participants.
