Twenty-four male wister rats were reared from weaning either alone (isolation reared) or in groups of five (socially reared) for 6 weeks.

Under high light in unfamiliar conditions isolation reared rats spent significantly more time in aggressive interactions (P<O.05) and high levels of aggressive behaviour compared to the socially reared rats (P<O.05).Isolation reared rats had spent less time in the open arms than the socially reared rats in the maze test…
