Depuis 40 ans, plusieurs milliers de recherches sont consacrées à l’amélioration de la compatibilité entre les situations d’apprentissage scolaire et les contraintes exercées par la mémoire de travail. L’objectif de cet article est de présenter quelques-uns de ces travaux. Nous montrons que quatre modèles successifs de la mémoire de travail ont lar...

Learning at school requires cognitive effort. Optimizing these efforts is one of the keys to academic learning achievement. Many controlled experiments, for example within the cognitive load theory framework, have identified the factors that impact this optimization. The temporal dimension of this optimization was evoked in 2018: certain academic l...

Objective For selection practitioners, it seems important to assess the level of mental resources invested in order to perform a demanding task. In this study, we investigated the potential of pupil size measurement to discriminate the most proficient pilot students from the less proficient. Background Cognitive workload is known to influence lear...

For a long time, Cognitive Load Theory has considered working memory models as tools to advance research on learning. It has used working memory capacity models, where working memory is viewed as being composed of a discrete number of slots (i.e., chunks) that can be kept active. However, recent results have shown that for a fixed quantity of infor...

Cognitive workload is of central importance in the fields of human factors and ergonomics. A reliable measurement of cognitive workload could allow for improvements in human machine interface designs and increase safety in several domains. At present, numerous studies have used electroencephalography (EEG) to assess cognitive workload, reporting th...

Verifying that a face is from a target person (e.g. finding someone in the crowd) is a critical ability of the human face processing system. Yet how fast this can be performed is unknown. The ‘entry-level shift due to expertise’ hypothesis suggests that - since humans are face experts - processing faces should be as fast – or even faster – at the i...

La théorie de la charge cognitive (CLT) permet de décrire l’investissement des ressources cognitives lors d’apprentissages scolaires. Cependant, elle présente deux limites, théorique et méthodologique. D’un point de vue théorique, la CLT utilise des modèles de la mémoire de travail (MdT), pour décrire les ressources cognitives utilisées lors des ap...

In this pilot study, we address the feasibility of coupling eye-tracking and electroencephalography to measure EEG rhythms associated with the processing of specific visual Areas of Interest. This method could provide new insights on cognitive processes in multitasking environments. 22 participants performed a multitask experiment embedding 4 concu...
