The term behavioural sciences encompasses all the disciplines that explore the activities of and interactions among organisms in the natural world. It involves the systematic analysis and investigation of human and animal behaviour through controlled and naturalistic observation, and disciplined scientific experimentation. It attempts to accomplish legitimate, objective conclusions through rigorous formulations and observation (E.D. Klemke, R. Hollinger & A.D. Kline, (eds.) (1980)). Examples of behavioural sciences include psychology, cognitive science, and anthropology.
The term behavioural sciences is often confused with the term social sciences. Though these two broad areas are interrelated and study systematic processes of behaviour, they differ on their level of scientific analysis of various dimensions of behaviour.
Behavioural sciences abstract empirical data to investigate the decision processes and communication strategies within and between organisms in a social system. This involves fields like psychology and social neuroscience, among others.
