The definite account of psychologist Jean Piaget's work Jean Piaget's influence on psychology has been profound. His pathbreaking investigations and theories of cognitive development have set child psychology moving in entirely new directions. His bold speculations have provided the inspiration for the work of others. His studies have been the subject of many books and countless articles. And, significantly, his influence has spread to other disciplines and is having an ever-growing impact on the general culture at large. Here Jean Piaget, with the assistance of his long-time collaborator Bäel Inhelder, offers a definitive presentation of the developmental psychology he has elaborated over the last forty years. This comprehensive synthesis traces each stage of the child's cognitive development, over the entire period of childhood, from infancy to adolescence.

"What is most impressive about this book is its intelligence, its sophistication, and its charm. . . . This book presents Piaget's work and his person better than anything else that I know about."—David Elkind, Tufts University "The tone is one of constant movement from the most ordinary to the most abstruse. There are 14 conversations with 'le Patron,' some in 1969, some in 1975, and several more with co-workers in various fields. . . . In Mr. Bringuier's book, in a pleasant informal way, we see a sophisticated non-scientist exploring Piaget's domain with the master. Some of Piaget's best-known findings about children as explained along the way, but Mr. Bringuier has ways of bringing out the relation of this psychological work to the whole of Piaget's enterprise, and we get a good sense of the man and his work."—Howard E. Gruber, New York Times Book Review

This book deals with the origins of intelligence in children and contains original observations on young children, novel experiments, brilliant in their simplicity,which the author describes in detail. Piaget divides the growth of intelligence into six sequential stages: the use of reflexes; the first acquired adaptations and primary circular reaction; secondary circular reactions and the child's procedures for prolonging spectacles interesting to him.

In the course of their researches for Mental Imagery in the Child (1971), the authors came to appreciate that action may be more conducive to the formation and conservation of images than is mere perception. This raised the problem of memory and its relation to intelligence, which they examine in this title, originally published in English in 1973. Through the analysis primarily of the child’s capacity for remembering additive and multiplicative logical structures, and his remembrance of causal and spatial structures, the authors investigate whether memories pursue their own course, regardless of the intelligence or whether, in specified conditions, mnemonic improvements may be due to progress in intelligence. They examine the relationship between the memory’s figurative aspects (from perceptive recognition to the memory-image) and its operational aspects (the schemata of the intelligence), and stress the fundamental significance of the mnemonic level known as the ‘reconstructive memory’. This was a pioneering work at the time, presenting illuminating conclusions drawn from extensive research, together with a number of constructive ideas which opened up a fresh approach to an important area of educational psychology.

This is Volume XX of thirty-two in the Developmental Psychology series. Initially published in 1954, in Piaget’s words the study of sensorimotor or practical intelligence in the first two years of development has taught us how the child, at first directly assimilating the external environment to his own activity, later, in order to extend this assimilation, forms an increasing number of schemata which are both more mobile and better able to inter-coordinate. This study looks at the second part of evolution of sensorimotor intelligence, as the description of behavior no longer suffices to account for these new products of intellectual activity; it is the subject’s own interpretation of things which we must now try to analyze.
