Reciprocal cross-fostering of mice was carried out between an inbred strain (C57 BL/6) in which the female showed a particular form of aggression toward lactating female intruders, and a strain (C3H/He) which proved to lack totally this type of attack. In adulthood, cross-fostered females of the 2 strains and their controls were submitted to a series of(More)

Learning through observation or vicarious learning has been systematically studied in a variety of animal species for only 20 years. Demonstrating in animals a capacity to benefit from a conspecific's experience, this type of acquisition was first thought to require superior cognitive processes and thus to be restricted to primates, if possible at all in(More)
Environmental preference of male rats reared during 2 months after weaning either in a complex and changing environment (EC) or in empty laboratory cages (SC) was assessed in 4 different experiments. For 2 weeks after differential rearing, rats were placed in groups of 6 in testing cages which were divided into 2 compartments with communicating holes. One(More)
