Empirical Evaluation Of The Effectiveness Of Eye Tracking-based Search Performance Diagnosis And Feedback MethodsCarroll, Meredith 01 January 2010 (has links)
In today's complex combat environments, troops are often faced with increasingly challenging tasks different from those experienced in the past. Warfighters must be trained in adaptive perceptual skill sets, such as search strategies that enable them to detect threats across any number of environmental, cultural, and situational conditions. The goal of the present study was to explore how advanced technology, specifically eye tracking, can be used to increase understanding of perceptual processes such as search and detection and provide tools that can be used to train search skills. Experiment 1 examined a method of diagnosing perceptual performance in order to be able to identify the perceptual root cause of target detection deficiencies and how these impact overall target detection performance. Findings indicate the method can be used to pinpoint where in the perceptual process a target miss originated, whether due to ineffective search strategy, inability to detect the subtle cues of the threat or inability to recognize these cues as indicative of a threat. Experiment 2 examined the training effectiveness of providing trainees with process level tailored feedback which incorporates elements of expert and trainee scan patterns. Findings indicate that providing trainees with elements of either expert or trainee scan patterns has the ability to significantly improve the search strategy being employed by the trainee. This work provides strong support for the use of eye tracking based perceptual performance diagnosis methods and training strategies in improving trainee search performance for complex target detection tasks.

Le sentiment d'employabilité des cadres seniors, secteur privé français : définition, opérationnalisation et déterminants. / Self-perceived employability of french senior executives and managers, private business sector : definition, operationalization and determinantsDeacken, Nadia 16 December 2015 (has links)
La notion de Sentiment d’Employabilité est imbriqué dans le concept de l’employabilité et est peu évoquée au niveau des pratiques managériales modernes. Les travaux académiques sur le sujet sont limités à l’heure où les individus, évoluant sur le secteur privé, connaissent des difficultés de repositionnement en avançant dans l’âge. Cette situation se vérifie aussi pour les cadres. Une revue de littérature étayée des concepts permet de livrer une conceptualisation en lien, à la fois, avec l’individu, les variables socio-démographiques et le marché du travail. Une étude qualitative a été menée auprès de plus d’une trentaine d’acteurs. Ensuite, sur la base de plusieurs échelles validées portant sur l’employabilité et la perception individuelle de l’employabilité (et de nouveaux items issus de la recherche exploratoire), nous avons bâti un questionnaire. L’étude quantitative a ainsi permis d’opérationnaliser le Sentiment d’Employabilité comme un construit avec six dimensions : Compétence, Formation Continue, Sentiment d’Efficacité Personnelle, Réseau , Techniques de Recherche d'Emploi, Connaissance de la Réalité du Marché. L' outil montre l’influence du Sentiment d’Employabilité sur la situation professionnelle. Le modèle montre que le fait d’être en activité a aussi une influence sur ce sentiment. Cette étude a vocation à être transposée à d’autres publics (les juniors) et à d’autres contextes culturels / Self-perceived employability as an integrated element of employability…nor has it been really mentioned in modern-day managerial practices. Academic research on the topic is quite limited. It’s almost non-existent when individuals are confronted with difficulties in changing jobs: a tricky context when they get older. An extensive literature review backs up these concepts and delivers an operationalization of the idea linked to the individuals versus socio-demographic variables and employment status. The suggested results are from a qualitative study carried out on more than 30 people. The results then led to a quantitative research on the operationalization of Self-perceived employability. Based on several confirmed scaled (with items linked to employability, and to a lesser extent, Self-perceived employability…and new items from the exploratory research), we built a questionnaire keeping in mind that this way could contribute to a new and innovative measurement of employability. The streamlined scale leads to a new construct with six statistical dimensions: Skills, Training, Sense of Self Efficacy, Networking (internal and external), Job Search Tools and realistic knowledge of the job market. All in all, the research offers a way which could forecast professional situations and allows a realistic evaluation of Self-perceived employability. This study also suggests that self-employability is linked to professional status (ie to be hired). This research could be used for other vulnerable groups (like junior workers) and also on different cultural contexts
