Construction d’un modèle intégré : interactions entre émotion et production d’un mouvement volontaire de l’ensemble du corps : application à l’initiation de la marche

Abstract : The purpose of this work was to study the interactions between emotion, cognition and movement in terms of approach-avoidance emotional dimension integrated on the production of a voluntary whole body movement: the preparation and the selection of gait initiation’s motor programs. An integrative model has been built in order to articulate four theories: those relating to the cognitive control of the movement, to the biphasic organisation of emotion, to the conflict monitoring and to the perceptual load. First, results provide new insights about gait initiation: this movement has an emotional significance in terms of its approach-avoidance direction. This movement production is dependent on the emotional context (pleasant/unpleasant) in which there is provided. Moreover, this dependance is even more important than emotional influence on reaction time and on the magnitude of the motor response of the medio-lateral axis could not be modulated by the implementation of cognitive (high level of cognitive control) and perceptual (high level of perceptual load) processes. In typical button press tasks, these processes are used to modulate the interactions between emotion and movement. In addition, results obtained on the approach-movement direction demonstrated a specificity of the anteroposterior postural control, since the emotional influence on its magnitude has been modulated (attenuated) by these same cognitive and perceptual processes.
