Errorless learning in the rehabilitation of memory impairment: a critical review

This review considers the origins of the errorless learning (EL) concept, its application in memory rehabilitation, the evidence for its effectiveness, and the theoretical basis for the observed findings. The evidence suggests that EL offers valuable benefits for at least some people with memory impairments when teaching certain types of tasks. However, the benefits are not evident for all groups, some findings are equivocal, and there are some limitations associated with this approach. We discuss methodological issues impacting on these mixed findings, consider which theoretical explanations might account for the findings regarding benefits and limitations of EL, and comment on the implications for rehabilitation practitioners of the current state of evidence in this area.
