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，表明儿童运动技能发展受损（或发育协调障碍- DCD）的基础是差异复制（或前馈计划）缺陷。该项目的目的是通过在大样本中纵向检验这一假设来推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、认知缺陷表现的变化，以及表现随年龄的变化。我们预测，差异拷贝的缺陷将解释大多数儿童偏离正常运动技能发展的原因。我们还预测意象训练将改善这一缺陷。

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.
