Sequence learning: Role of action observation and action

点击翻译按钮获取中文摘要

While the performance and learning of movement sequences has received a good bit of experimental attention, little if any focused attention has been directed at participants* ability to observational practice and sequence learning. This is a critical practical issue because performers often observe the movement sequence that will be performed afterwards. Observational practice and sequence learning are also of considerable theoretical interest because observing how performers acquire a movement sequence without physical practice should provide valuable insights into the fundamental ways in which movement sequences are structured, stored, and executed. The primary purpose of the present proposal is to identify the conditions under which and the process by which observational practice improves movement sequence learning. These questions will be investigated in the first two experimental series. The second purpose is to record the eye movement during observation of a sequence performed by a model. We want to determine whether predictive eye movements are displayed during the observation of a sequence movement as displayed in visually guided actions. The question of eye movements will be investigated in experimental series 3.January 09 - December 09: Experiments 1A - 1CJanuary 10 - December 10: Experiments 2A & 2BJanuary 11 - December 11: Experiments 3A &
