A patient with organic anterograde memory disorders was previously reported as having a dissociation between recall and clustering on categorical effects (normal recall and lower clustering) in an incidental learning situation. To further study the recall-clustering relationship in the amnesic patient, the present experiment was conducted in an intentional learning. In order to compare with the incidental learning, the same words used in the previous experiment were presented. It was discovered that recall and clustering of the patient were significantly lower than those of normal controls. The comparison between the learning situations showed that while clustering was substantially facilitated due to the intention to learn, recall was not elevated. The results confirmed the dissociation of recall and clustering in the patient. The role of clustering in a free recall was discussed.
