Nineteenth-century developmental psychologist Jean Piaget examines the child's notions of reality and causality at various stages of development.

This classic examines the child's notions of reality and causality.

Our encounters with the physical world are filled with miraculous puzzles-wind appears from somewhere, heavy objects (like oil tankers) float on oceans, yet smaller objects go to the bottom of our water-filled buckets. As adults, instead of confronting a whole world, we are reduced to driving from one parking garage to another. The Child's Conception of Physical Causality, part of the very beginning of the ground-breaking work of the Swiss naturalist Jean Piaget, is filled with creative experimental ideas for probing the most sophisticated ways of thinking in children. The strength of Piaget's research is evident in this collection of empirical data, systematically organized by tasks that illuminate how things work. Piaget's data are remarkably rich. In his new introduction, Jaan Valsiner observes that Piaget had no grand theoretical aims, yet the book's simple power cannot be ignored. Piaget's great contribution to developmental psychology was his "clinical method"-a tactic that integrated relevant aspects of naturalistic experiment, interview, and observation. Through this systematic inquiry, we gain insight into children's thinking. Reading Piaget will encourage the contemporary reader to think about the unity of psychological phenomena and their theoretical underpinnings. His wealth of creative experimental ideas probes into the most sophisticated ways of thinking in children. Technologies change, yet the creative curiosity of children remains basically unhindered by the consumer society. Piaget's data preserve the reality of the original phenomena. As such, this work will provide a wealth of information for developmental psychologists and those involved in the field of experimental science. Jean Piaget (1896-1980) is known for investigations of thought processes. He was professor at Geneva University (1929-1954) and director of the International Center for Epistemology (1955-1980). He is the author of The Language and Thought of the Child, Judgment and Reasoning in the Child, The Origin of Intelligence in Children, and The Early Growth of Logic in the Child. Jaan Valsiner is professor of psychology at Clark University, and a recognized authority on the life and work of Piaget.

This book was first published in 1970.

However unthinkable child-soldiers may be within a generalized conception of childhood, they are not imaginary figures; rather, they are a constant in almost every armed conflict around the world. The participation of children in wars may question the idea of childhood as a "once-upon-a-time story with a happy and predictable ending," disrupting the (natural) idea of a protected and innocent childhood and also eliciting fear, uncertainty, revulsion, horror, and sorrow. Using the perspectives of both childhood studies and critical approaches to international relations, Jana Tabak explores the constructions of child-soldiers as "children at risk" and, at the same time, risky children. More specifically, The Child and the World aims both to problematize the boundaries that articulate child-soldiers as necessarily deviant and pathological in relation to "normal" children and to show how these specific limits participate in the (re)production and promotion of a particular version of the international political order. In this sense, the focus of this work is not on investigating child-soldiers' lives and experiences per se but on their presumed threatening feature as they depart from the protected territory of childhood, disquieting everyday international life.
