Neonatal novelty exposure enhances both short-term (10 min) and long-term (24 hr) social recognition memory. a, Novel and Home rats did not differ in baseline social investigation (D1S1). b, Novel rats showed significantly greater reduction in social investigation than Home rats after 10 min ITI (STH). c, Novel rats showed significantly greater reduction in social investigation than Home rats after a 24 hr delay (LTH). d, Interference effect from a single exposure to a new conspecific: LTH in the Novel but not Home rats was significantly reduced by the exposure to a new conspecific. *p < 0.05; **p < 0.025; ***p < 0.01.
