Previous work indicates that mice of different genotypes reared in enriched environments show differential increases in performance on a food‐seeking task. In this study 2 experiments examined the effects in selected mice strains of short exposures to such enrichment. Experiment 1 indicated that 48 hr of exposure to enriched cages was sufficient to produce results found previously when subjects were reared from birth in enriched cages. Experiment 2 indicated that as little as 6 hr of exposure to an enriched cage was sufficient to produce almost maximal enrichment effects in C57BL/10J mice.
