Influence de la composition de la fratrie sur les pratiques éducatives parentales déclarées et sur la représentation de l'éducation chez les préadolescents

The aim of our study is to analyze the influence of the make up of the siblings on the parents' educational practices and also on the meaning of education to preadolescents. The results gathered from a sample of 88 preadolescents and their mothers show a difference of parental educational practices according to the make up of the siblings (relaxation of the practices with the youngest). The study of the meaning of education to preadolescents shows that only children are the most in accordance with their mothers. Children from large families imagine a future education further from mothers' educational practices.     

Psychologie, épistémologie et théorie de la représentation : fondation analogique et données séminales

Our scientific systems mirror our mental constraints: the limits of our mental representations lead us to a better reconstitution of the world by some scientific theories. Thus, the ways of representation by a mental system provide a fruitful paradigm for epistemology. To tackle this point, we start from an experiment of psychology on the impact of seed data on the representation of geography. We try to generalize the concept of seed data in the framework of the theory of analogical foundation of representations. A parallel is outlined between: 1) the integration of a piece of information into a mental system; 2) the integration of data into a scientific system. We bring up some consequences about the fonction of experimentation.
