Rôle des représentations d’action et du système moteur dans la construction du soi : synthèse et perspectives

Is there any Influence of Variations in Context on Object-Affordance Effects in Schizophrenia? Perception of Property and Goals of Action

“…Patients expressed, for example, knowing how to set a table but needing to think about each step to accomplish the task. Jeannerod (2001) , Gallese (2009) , and Vandevoorde (2011) agree that it is precisely this sensorimotor simulation that not only enables the subject to anticipate an action but provides as well a “motor thought,” an automatic, almost intuitive knowledge from his surrounding world. This ability to anticipate his actions should allow the subject to act seamlessly in his environment and feel familiar with it and current social situations.…”

“…The presentation of a congruent prime would enable the preparation of motor action, resulting in the emergence of the affordance effect. Indeed, Vandevoorde (2011) showed that an efficient coupling between the perception of and action associated with an object that is perceived beneficial to the subject will facilitate the reactivation of this kinesthetic image in a similar situation by reinforcement and motor habituation. In this case, the object becomes a “visuomotor opportunity” ( Rizzolatti and Sinigaglia, 2008 ) that is identified based on its motor potentialities.…”

“…Such a view posits that cognition emerges from the cooperation and co-evolution of perceptual and motor systems that allow sensorimotor patterns to be implemented. Perception is therefore more proactive toward than reactive to the individual’s environment ( Berthoz and Petit, 2003 ; Rizzolatti and Matelli, 2003 ; Gallese, 2007 ; Barsalou, 2008 , 2009 ; Vandevoorde, 2011 ); it’s an internal simulation of action, designed for understanding the meaning of his environment ( Berthoz, 2003 ). The subject builds the world in which he lives and acts, in accordance with his perception of that environment ( Glenberg et al, 2013 ) and the actions he performs within it.…”

Troubles de la réalisation d’action et dépression avec activité suicidaire

“…De cé lè bres travaux de neurophysiologie fondé s, entre autres, sur des mé thodes neuro-phé nomé nologiques ont ré cemment fait des dé couvertes majeures dans le domaine de la production d'action, depuis l'é quipe de Rizzolatti et la dé couverte des neurones miroirs au dé but des anné es 1990 [41] aux travaux d'Alain Berthoz sur la genè se de l'action [2], de Marc Jeannerod sur la simulation motrice [25][26][27][28][29][30], de Benjamin Libet sur le rapport conscience-action [35], d'Alain Damasio sur le rô le des é motions [12], et de nombreux autres [1,4,10,22,42,45]. L'inté rêt pour l'action ne s'est pas limité à la physiologie mais a suscité des recherches dans d'autres cadres thé oriques comme la psychologie du dé veloppement avec la sensori-motricité de Jean Piaget, ou des travaux psychanalytiques sur la pensé e motrice et la construction du soi [8,9,18,19,31,32].…”
