Description des données d'observation continue du comportement par une technique d'analyse de textes. 2. Comparaisons...

This study illustrates the use of multifactorial analysis to perform comparisons between different genotypic groups, based on behavioral profiles. Maternal behaviour of C57BL/6 mice and of two reciprocal F2 was precisely described by continous observation. Unpolished data were directly analysed by a textual analysis technique using correspondences analysis. Strains were clearly different according to the relative frequencies of the different acts. These differences seemed to be related to grand-maternal effects, as previously shown in the same strains. Pups age related variation between day 2 and day 6 was very low when compared to maternal styles of the three strains.
