Latency (in seconds) data as a function of retention interval

	1 h	4 h	24 h	48 h	CON	2-MIN
Sample	6.4 ± 0.4	8.1 ± 0.3	7.5 ± 0.5	8.3 ± 0.5	NA	NA
Test	6.9 ± 0.4	8.3 ± 0.6	6.5 ± 0.5	8.7 ± 0.6	7.3 ± 0.5	5.9 ± 0.6

Means ± SEM. All data are expressed in seconds. Data shown are from performance at 12 months of age. Mean latencies during long-delay test trials (1–48 h), control (CON), or 2 min (2-MIN) test trails were not significant [long-delay test trials (RM-ANOVA, F_(3,63) = 1.12, p > 0.25); CON vs 2-MIN trial (paired t test, p > 0.20)].
