Experimental Psychology Its Scope and Method: Volume VUpplaga 1

First published in English in 1968, Joseph Nuttin contributes the first chapter, on Motivation. He discusses various aspects of the motivational process. Such as incentives, conflict, social motivation, and negative motivation, and describes the mechanism of the process. The second chapter, by Paul Fraisse, is on the Emotions. Fraisse examines the nature of the emotions, both on the behavioural and on the neurophysiological levels, and goes on to define and discuss moving situations. He shows the different types of expression an emotional reaction may take, and discusses the causes of hyper-emotionality.

Richard Meili writes on the Structure of the Personality, showing the importance of the idea of trait in the psychology of personality. He describes the use of the factorial method in the analysis of personality, and gives an account of the beginnings of personality, as well as the different parts, known as instances, of the total organization of personality.
