Apprentissage procédural moteur et mémoire procédurale dans le trouble développemental de la coordination : études comportementales, en électroencéphalographie et en imagerie par résonance magnétique

Abstract : Developmental Coordination Disorder (DCD) is characterized by impaired motor skills. While the motor control deficit is unambiguous, studies testing motor procedural learning are few and lead to contradictory results. The main objective of this work is to understand the conditions under which children with DCD demonstrate a procedural learning and procedural memory deficits. Four studies were conducted to compare the motor procedural learning of children with and without DCD. We tested various learning behavioural tasks such as learning a new bimanual coordination, learning perceptual-motor sequences and learning rhythmic motor sequences in different conditions. We investigated the associated functional and structural brain correlates, using electroencephalography and magnetic resonance imaging. The results indicate some behavioural and brain differences during learning tasks, revealed by specific variables. In addition, some experimental conditions have improved the procedural learning and procedural memory of children with DCD. These results suggest that conditions in which procedural learning and memory of children with DCD are improved could contribute to better therapeutic interventions.
