Abstract
The ultimate purpose of this study is to clarify the structural relationships between ‘knowing that’ and ‘knowing how’ in performance in sport.
In the part 1, the purpose is to consider the structure of cognitive system, and the limits of language and seeing in the cognitive system.
The results are as follows:
As to the structure of cognitive system;
1) There are various kinds of ‘knowing that’ levels.
2) ‘knowing how’ is a kind of ‘knowing that’, and it is nothing else but sensorimotor cognition which can be bodily understood.
3) The synthetical knowledge concerned with the cognitive system or the motor system can not be essentially verbalize. Tried to verbalize the synthetical knowledge, it will change to the analytical knowledge.
As to the limit of language in the cognitive system;
1) We can not verbalize the tacit knowledge because of a synthetical knowledge.
2) When we are trying to express any object by language, we can not express all features but can do only some distinctive features.
As to the limits of seeing in the cognitive system;
1) The cognition only by seeing leads to misunderstand both phenomenal and conceptual knowledge.
2) Models or demonstrations which are far from performer's experience, do not help to develop his capacity of movement-sympathy because he can not unify sensually with the models or demonstrations.
