Overview and ways forward for future research.

This Special Issue of Neuropsychological Rehabilitation on errorless learning in rehabilitation of language and memory impairments includes one review and six empirical studies, which present new clinical findings evaluating the effectiveness of errorless learning as an intervention method for people whose symptoms stem from different neurological aetiologies. These studies delineate some of the critical theoretical-clinical issues through which we might optimise learning and rehabilitative efforts more fully.
