Rôle des afférences proprioceptives dans le développement de l’imagerie motrice chez l’enfant.

Abstract

To which extent is motor imagery (MI) development, commonly observed between the ages of 5 and 9, related to the increasing ability to integrate proprioceptive afferences for the control of action? This question was addressed in a study evaluating MI performance of 108 children aged 5, 7 and 9 years old. A mental chronometry paradigm based on a walking task was used. Integration of proprioceptive information was evaluated by comparing MI performance when children held an external load (5 % of the children weight) to when they did not. Results revealed that the external load affected MI performances of the 5 year olds. In 7 years old, MI performances remained unchanged whether they held an external load or not. At 9 years, holding an external load improved MI performances. Taken together, these results reveal that MI development could be linked to proprioceptive acuity refinement during childhood. These results are discussed according to the relation between MI, proprioceptive development and development of internal models of action during childhood. (PsycINFO Database Record

Action representation deficits in adolescents with developmental dyslexia

“…Indeed, according to developmental studies, forward models are acquired by learning during childhood through the repetition of sensorimotor experiences. The acquisition of a systematic relation between the motor commands, the environment, and the sensory feedback generated by the movement execution will progressively allow the formation of an accurate action representation or mental movement simulation (Caeyenberghs, Tsoupas, et al ., 2009; Caeyenberghs, Wilson, et al ., 2009; Crognier et al ., 2013; Guilbert, Molina, & Jouen, 2016; Molina, Tijus, & Jouen, 2008). Therefore, the general proprioceptive dysfunction identified in DD (Quercia et al ., 2020; Quercia et al ., 2005, 2007) could be one of the origins for the action representation deficit.…”

Digital touchscreens as a media for creativity during adolescence

“…Studies investigating motor imagery sustain this proposal. Indeed, it has been demonstrated that the easiness to simulate motor action in children is clearly linked to the richness of the afferent set of information children (Guilbert, Jouen, Lehalle, & Molina, 2013;Guilbert, Molina, & Jouen, 2016) and adolescents (Choudhury, Charman, Bird, & Blakemore, 2007) can refer to although they are not enrolled in a real action. This process of simulation has been recently proposed to give account for creativity, a cognitive process based on sensorimotor prediction.…”
