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)
This paper presents the results of a study conducted on the interaction of two disfluencies: repeats and word fragments. It is based on 150 repeated word fragments (e.g., " on le re-re-revendique encore une fois ") extracted from a one-million-word corpus of spoken French. Word fragments such as: " notre métier spé-spécifique " , are, like repeats (e.g., "(More)
A method is described of assessing whether or not social facilitation occurred in a troop of Guinea Baboons (Papio papio) living in an enclosure. The method did not involve the removal of individuals from the troop. The study revealed an interaction between social facilitation and the quality of social relationship involved; affiliative relationships(More)
Large annotation projects, typically those addressing the question of multimodal annotation in which many different kinds of information have to be encoded, have to elaborate precise and high level annotation schemes. Doing this requires first to define the structure of the information: the different objects and their organization. This stage has to be as(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)
Male and female rats of the inbred August and Fischer strains were reared during two months after weaning either in a standard laboratory environment (controls) or in a more complex environment (treated animals). The performance of these rats was measured afterwards in an operant conditioning situation with positive reinforcement. The multiple reinforcement(More)
