The development of feedforward mechanisms of motor control: The role of efference copy in motor skill development.

我们的工作提供了初步的证据，在传出复制（或前馈计划）缺陷的基础上受损的运动技能发展的儿童（或发展协调障碍- DCD）。本项目的目的是通过在大样本中纵向检查这一假设，来促进我们对正常和异常运动发育的理解。 我们将研究不同亚型中笨拙表现的变化、认知缺陷以及表现随年龄的变化。我们预测，缺陷的传出复制将解释偏离正常的运动技能的发展，在大多数儿童。我们还预测，意象训练将改善赤字。

Our work provides preliminary evidence that deficits in efference copy (or feedforward planning) underlie impaired motor skill development in children (or Developmental Coordination Disorder - DCD). The aim of this project is to advance our understanding of normal and abnormal motor development by examining this hypothesis in a large sample, longitudinally. We will examine variations in the presentation of clumsiness, cognitive deficit(s) in different subtypes, and changes in presentation with age. We predict that deficits in efference copy will explain departures from normal motor skill development in most children. We also predict that imagery training will ameliorate the deficit.
