Child psychology is additionally referred to as kid development, the study of the psychological processes of kids and, specifically, however these processes dissent from those of adults, however they develop from birth to the top of adolescence, and the way and why they dissent from one kid to ensuing. Child psychology studies the interaction of some main areas of development: Physical Development, Cognitive development, Emotional Development, Mental illness in kids, Mental disorder in kid’s square, Anxiety, Depression, Bipolar Disorder, Schizophrenia, Autism Spectrum Disorder. Child psychology is a curious hybrid as far as theory building is concerned because it is a part of the general area of comparative psychology on the one hand and a part of the area of developmental psychology on the other. Child psychology is interested in building a theory about the behavior of children. We wish to be able to predict how a child will behave in any specified stimulus situation. Since children behave differently from adults in many of the same situations, an adequate theory of human behavior must contain concepts and parameters which will enable it to encompass the behavior of children. One task of child psychology is to contribute to such a behavior theory by comparing and contrasting the behavior of children and adults, children of different age levels as weIl as children of different background, racial origin, etc., when they are placed in the same situation. The findings of such comparative studies pose problems for behavior theory, and child psychologists are in a position to contribute to their solution. Thus we must assess research in the field in terms of its contributions to a theory of human behavior, especially to a theory of the behavior of children. This is the role of child psychology as a part of comparative psychology. As an area in developmental psychology, child psychology is concerned with different phenomena. Here it must make its contribution to a theory of change of behavior. We want to know not only how children behave but also how they become adults. We are interested in situations both as stimuli to behavior and also as antecedent conditions which change a child's personality. We must therefore look at research in child psychology from two points of view, as a contribution to behavior theory and as a contribution to developmental theory.
