Etude neuropsychologique des rapports entre outil, geste et usage

Abstract : The investigation of object use impairement raises the question of the nature of psychological enabling the ability to use tools. It has suggested that this disorder might result from excutive deficts and/or the inability to retrieve sensory motor knowledge about object manipulation (i.e., gesture engrams). Since manufactured objects are always designed to a specific conventional purpose, it has also been assumed that patients with objet use impairemnt might suffer from detective conceptual knowledge about object function. The present thesis proposes an alternative view by suggesting the object use depends upon a specific technical, rational and implicit ability to analyse natural activity. To contribute to the discussion, we address many epistemological and theoretical issues about the definition of human tool, and report four studies with brain-damaged patients that aimed to examine the relevance of the concepts of "tool", "gesture" and "usage". In sum, the present thesis suggests that the investigation of object use impairement would gain by conceiving this disorder as a singular inability to use tools.
