De quoi parlons-nous quand parlons de psychosociologie?

Psychosociology, as knowledge and practice, is often evasive because of numerous theoretic references and models of intervention. This article, from the concept of the project by George Canguilhem, wants to identify psychosociology as action/research on the processes through which the social reality is created in its organized forms. The author underlines particularly the independence which characterizes these processes. The article presents a case of formation in a sanitary contest, which shows the complex combination of different elements (organized aims, conscious and unconscious fantasy, knowledge, techniques… ) through which the organized life takes form.
