An inherent component of tool‐use actions is the transformation of the user's operating movement into the desired effect. In this study, the relevance of this transformation for young children's learning of tool‐use actions was investigated. Sixty‐four children at the age of 27–30 months learned to use levers which either simply extended (compatible transformation) or reversed (incompatible transformation) their operating movements. Data revealed a compatibility effect as well as transfer effects originating from the two different types of transformations. Furthermore, results suggest that young children's tool‐use learning is not a uniform process, but has to be regarded individually depending on the type of transformation. [ABSTRACT FROM AUTHOR]
