Behavioural psychology emphasises an experimental-clinical approach to the application of behavioural and cognitive sciences to understanding human behaviour and developing interventions to enhance the human condition. Behavioural psychologists engage in research, education, training, and clinical practice regarding a wide range of problems and populations. The distinct focus of behavioural psychology is twofold: (a) its strong reliance on an empirical approach; and (b) its theoretical grounding in learning theories, broadly defined, including respondent conditioning, operant learning, social learning, cognitive sciences, and information processing models. This book presents new international research in this important field.
