Memory performance of patient E.P.

	Diagram recall	Paired associates			Word recall (%)	Word recognition (%)	Words (50)	Faces (50)
E.P.	0	0	0	0	24	65.3	24	28
Controls	20.6	6.0	7.6	8.9	71.0	97.4	48.4	41.9

The diagram recall score is based on the delayed (12 min) reproduction of the Rey–Osterrieth figure (Osterrieth, 1944; maximum score, 36). For copying the figure, patient E.P. obtained a normal score (27; controls, 26.7; Kritchevsky et al., 1988). The paired-associates score is the number of word pairs recalled on three successive trials (maximum score, 10/trial). The word recall score is the percentage of 15 words recalled across five consecutive study-test trials (Rey, 1964). The word recognition score is the percentage of words identified correctly across five successive study and test trials (yes–no recognition of 15 new words and 15 old words). Note that the scores on the recall test are above zero because on this test of immediate recall, several items can be retrieved from immediate memory, which is intact in E.P. The scores for words and faces are based on a 24 hr recognition test of 50 words and 50 faces (modified from Warrington, 1984; maximum score, 50; chance, 25). The mean scores for the controls (n = 8) are from Squire and Shimamura (1986).
