The Early Growth of Logic in the Child.
Inhelder, Barbel; Piaget, Jean
Analyzed are the processes of classification and seriation which form the child's ability to reason, based upon the results of eight years of experimental work with over 2000 children. The authors have found that there is a very close relation between the development of logical actions and that of sub-logical operations and actions. The fact that classificatory unions and subdivisions reach back to a primitive origin in actions means that the child has a very long way to go from the early and ill-differentiated functional aggregates to arrive at true classificatory concepts. The logical development of the child occurs in three stages. The first stage is characterized by a lack of differentiation between the logical and the sub-logical. At stage II, there is partial differentiation; at stage III they are completely differentiated, and the child has arrived at true classificatory concepts and is able to perform reversible operations. Logical operations (i.e. in particular, classification and cross-classification, and seriation and multiple seriation) are closely linked with certain actions which are quite elementary: putting things in piles, separating piles into lots, and making alignments.
