1. Ibos, Guilhem. Orientation volontaire de l’attention visuelle chez l’homme et le macaque Rhésus : Voluntary orientation of visual attention in human and macaque monkeys.

Degree: Docteur es, Neurosciences, 2009, Université Claude Bernard – Lyon I

L’attention visuelle est un phénomène primordial pour la perception visuelle de notre environnement. Elle correspond à l’ensemble des mécanismes qui permettent la sélection d’information visuelle dans le but de la traiter en particulier. Lorsque volontaire, son orientation est considérée comme lente, contrairement à l’orientation de l’attention visuelle involontaire, qui est rapide et réflexive. Grâce à une étude de psychophysique humaine, nous montrons que le déplacement volontaire de l’attention est rapide mais qu’un ensemble de processus cognitifs ont jusqu’à présent masquer ce phénomène.Au niveau cérébral, l’orientation de l’attention visuelle est sous tendue par un réseau d’aires,impliquant le champ oculomoteur frontal (FEF) et l’aire latérale intrapariétale (LIP). En enregistrant l’activité unitaire des neurones de ces 2 aires de 2 macaques Rhésus impliqués dans une tâche de détection de cible nécessitant l’orientation volontaire de l’attention visuelle,nous montrons que ces 2 aires jouent un rôle différent. Ainsi FEF semble impliqué dans l’orientation des capacités attentionnellles et représente également la sélection de l’objet important. LIP n’est pas impliqué dans l’orientation de l’attention visuelle, en revanche, ses neurones présentent une réponse cognitive spécifique de la détection de la cible. Nos résultats suggèrent que FEF contrôle l’orientation volontaire de l’attention visuelle alors que LIP sert à la détection de la cible.Qui plus est, nous montrons l’existence dans FEF d’une nouvelle classe de cellules impliqués dans le contrôle exécutif des fonctions cognitives et notamment attentionnelles

Visual attention is a critical process to a correct perception of our visual environment.This term includes all mechanisms involved in the selection of information in order to processit in priority. It is generally proposed that voluntary orientation of attentional capacity is a220slow and sustained process, while unvoluntary orientation is fast. We show here by apsychophysical study that voluntary orientation is in fact a rapid process that is easely maskedby others cognitiv process of general engagement.This phenomenon is sustained by a large network of cerebral areas, including the Frontal Eye Field (FEF), and the Lateral IntraParietal area (LIP). We recorded neuronal activity of 2monkey’s FEF and LIP neuronal activity while they were engaged in a attentional task. Weshow here that these 2 areas play 2 crucial differents roles. Contrary to FEF, that is highlyinvolved in attentional orientation and engagement, LIP neuronal activity present few attentional modulations. LIP and FEF cells present large cognitive activities selectives to selection of the important event of the task. We hypothesis that FEF controles the voluntary orientation of visual attention while LIP detects the target.More over, we highly the existence of a new FEF’s cell category involved in the executive control of cognitives function (as attentional).

2. Senez, Bertrand. Le discernement d'une reconversion professionnelle congruente source de satisfaction durable.

Degree: 2020, Université de Sherbrooke

Abstract: The profound changes in the world of work in recent decades have led to a change in professional careers and correlated with the way in which career guidance is envisaged. In an increasingly changing world, the possibility of lasting satisfaction is now being questioned. The present research is concerned with the decision of occupational bifurcation of persons who could have continued their professional activity, but who decided to change it, and proved to be sustainably satisfied. Going back to the moment of discernment of their new professional orientation, it was a matter of understanding what these people were attentive to in making their decision. Several theoretical contributions have been mobilized to apprehend this professional discernment. A review of the points of attention, that is to say of what a person who orients oneself is attentive to make his decision, has been carried out on the basis of both research on career guidance and research on job satisfaction. The general analysis of voluntary choice at Aristotle was also useful in identifying the components of a career choice. A qualitative approach was chosen to understand, from the point of view of the discerning subject, what enabled him to make a congruent decision, source of lasting satisfaction. The phenomenological analysis of the interviews of six participants revealed the appropriateness of a three-dimensional congruence as a guarantee of lasting satisfaction, this being understood as eudemonic well-being. The purpose of work, the nature of the activity and the working environment constitute these three dimensions and make it possible to renew the understanding of the concept of congruence in a factor-based approach, and at the same time to consider the adaptability advocated by the constructivist approach. On the other hand, discernment has appeared as a dynamic process that brings together objective characteristics estimated by the subject and a variety of appetites that are considered and explained by the same subject. This process leads, in various ways, to the formation of an object-end which constitutes the concrete professional activity chosen by the subject. The Aristotelian analysis of the voluntary choice used was confirmed but also supplemented. In particular, discernment has appeared not only as the search for a means suitable for an end, but also as a process that allows an end to emerge and that corresponds to a person who is always singular. Finally, this research sketches a personalist approach to guidance that integrates the concerns of the traits-factors approach and the constructivist approach. This personalist approach tries to discover references in order to discern, in a more moving and unstable contemporary context, an orientation that makes it possible to find and reveal oneself in one’s professional activity. It makes it possible to better understand, from the point of view of the person himself, what allows a congruent decision source of lasting satisfaction of adults in voluntary vocational retraining.
