Data represent mean ± S.E.M. for the frequency of headpoke and rearing behaviors during 10-min open field test in rats differentially housed for 3 or 50 days.

↵5-150 Indicate a significant difference from singly housed group (p = .05).
↵5-160 Indicates significant difference from 3-day group (p≤ .05).
