The scientific study of all forms of human and animal behaviour, sometimes concerned with the methods through which behaviour can be modified is collectively known as psychology. Various psychologists in different parts of the world propounded their theories, counter-theories after painstaking research and experiments. And thus, gradually psychology developed as a discipline in leaps and bound. Now psychology is not relied upon by educationists only but social scientists, judicial and police officials, industrial/business organisations and even politics and international relations also heavily depend on psychology. The present work covers all prominent psychologists from different countries of the world. Alphabetically arranged with names, their short biorgraphical sketch, research and theories propounded, major published works and an analytical note on their theories are the salient features of this encyclopaedic work which provides instant information about the world great psychologists. This will prove an asset to researchers, academics, psychologists, psychiatrists .and other educational scientists besides the general readers inclined to study human(animal) behaviour in different perspectives.
