Impaired Multidimensional Motor Sequence Learning
Inability to learn a dimension of movement with practice in response to specific task demands during a motor task requiring serial, patterned movement. The three primary dimensions are: (1) motor (movement command), (2) spatial (movement in space), and (3) temporal (timing of a movement).
Learning motor skills involves integrating many elements of a movement in an environment in order to successfully perform the desired response consistently over time. Most “real-life” skills involve sequential movements to complete a task. In a controlled laboratory setting, these elements are usually tested in isolation making it difficult to deduce which elements are most salient to acquisition of a given skill. Every movement dimension (motor, spatial, and temporal) requires a certain level of precision for successful skill production. For example,...
