Method for the rehabilitation of memory disorders, particularly in patients with dementia of Alzheimer's type, allowing the acquisition of new information (Camp, 1989). The principle of the method is as follows: the subjects' memory is evaluated by gradually increasing the retention interval between two tests. When a retrieval failure occurs, the retention interval is reduced to the previous interval that resulted in a correct recall. Then the interval is increased again until a correct recall occurs. The procedure is therefore adapted according to the performance of the subjects.
