Learning new face-name associations with spaced retrieval strategy on a patient with Alzheimer-type dementia

This study describes the use of the Spaced Retrieval Strategy (SRS) for learning new face-name associations in a woman with Alzheimer-type dementia (DAT). N.C. shows severe episodic memory deficits but intact implicit memory. As SRS probably relies on implicit memory, it is hypothesized that favoring implicit retrieval, rather than explicit retrieval, could allow for learning to occur. Results seem to indicate that it is the case, as N.C. only learned face-name associations under implicit memory instructions. However, additional testing revealed important proactive interference with both instructions. This could be explained by N.C.'s incapacity to inhibit irrelevant answers. It is suggested that SRS and errorless learning should be combined to optimize acquisition of new information in DAT patients.
