Table 5. Immediate recall and intrusion errors.

	Early group	Late group	Early vs. late		Control group
Test	X (SD)	X (SD)	t test	P value	X (SD)
WMS, immediate recall of stories (%)	29.5 (9.56)	15.0 (4.64)	3.25	0.013	40.9* (14.40)
WMS, trial 3 of paired associates, (/10)	6.7 (1.51)	4.6 (0.55)	3.12	0.018	9.6* (0.73)
WMS, digit span, forward	6.3 (0.52)	5.2 (1.79)	1.49	0.169	6.6* (1.21)
CAVLT-2, total intrusions	19.5 (8.31)	5.8 (3.11)	3.46	0.007	(range, 0-4)†

Scores are means (X) and SDs (or range where indicated). (Digit Span forward is listed here because late, but not early, group differed significantly from control group. See Neuropsychology Results.)

^*Normal controls (n = 36, mean age = 14 years, range 12-17 years).
