Experimental Psychology Its Scope and Method: Volume VII

First published in English in 1969, the book opens with a chapter by Pierre Oléron on intellectual activities. It describes typical methods and essential results obtained by relevant experiments.
There are two chapters by Jean Piaget and his collaborator Bärbel Inhelder. The first, on mental images, breaks new ground: it describes original experiments carried out by Piaget and associates with children of various ages. The second chapter is on intellectual operations and Piaget gives a summary of the main findings of a number of his earlier books.
In the last chapter, Pierre Gréco discusses learning and intellectual structures.
