MOTOR SKILLS: DEVELOPMENT, IMPAIRMENT, AND THERAPY
Authors: A. M. Keane
Abstract: The often held view that motor control occurs largely as the final stage of cognitive processing is something that still needs to be dispelled. Granted that while there is a final level of motor control, all-be-it a lower level of motor control, this is only one level in the motor control hierarchy. Some inroads have been made in clarifying the different stages of motor control and its lateralization, however there is still a way to go with regards to delineating the various levels of motor control from the very highest or early inception/goal level to the final level of movement execution, as well as how each of these levels contributes to bimanual control, hand preference, hand proficiency and overall motor skill. Also, how exactly posture figures within the motor control hierarchy and its influence on final motor skill needs to be taken into account. Motor control is not separate from cognitive functioning, the two are intimately linked, and so the challenge within this area and one of the main directions for future research is the need to find the cognitive and language functioning associated with each respective level of motor control, thus clarifying the cognitive – motor skills link.
