The locus of the benefits of repetition-lag memory training

Abstract

The repetition-lag training procedure developed by Jennings and Jacoby (2003 , Neuropsychological Rehabilitation, 14, 417) has been shown to improve older adults' performance in the recognition memory task used for training, and to improve performance in a variety of other memory and executive function tasks ( Jennings, Webster, Kleykamp, & Dagenbach, 2005 , Aging, Neuropsychology, and Cognition, 12, 278). The present study examined the effects of concurrent interference tasks during the study or test phases of training to localize the source of gains. Overall, the results suggest that training is resilient and resistant to interference, but also that the processes used during the test phases of training are more important to the gains seen in the primary task and in the transfer tasks than those used in the study phases.
