TL;DR
A general theory of skill acquisition will only result from consideration of the ramifications of a multi-level process-oriented description of skilled performance.
Abstract
The analysis of skilled performance must proceed at many levels. As illustrated in the two experiments presented here, what we observe in human skilled behavior is the rich intermingling of these various levels of control as a function of the task demands, the state of learning of the subject and the constraints imposed on the task and the subject by the environment. While we should be interested in the neurophysiological correlates of such behavior we still have a long way to go even to understand what to expect in terms of the behavior itself. The job of the researcher is different depending on the level of analysis at which he is interested, but a general theory of skill acquisition will only result from consideration of the ramifications of a multi-level process-oriented description of skilled performance.
