Beschreibung:
Originally published in English in 1976, the book draws on and extends our knowledge of the process of learning. The subject of the study is the general stage in a child's development that comes between his successful performance of an activity without knowing how he did it - that is, what he had to do in order to succeed - and the times when he becomes aware of what went into that action.
