The term behavioral sciences encompasses the various disciplines and interactions among organisms in the natural world. It involves the systematic analysis and investigation of human and animal behavior through the study of the past, controlled and naturalistic observation of the present, and disciplined scientific experimentation. It attempts to accomplish legitimate, objective conclusions through rigorous formulations and observation. Examples of behavioral sciences include psychology, psychobiology, anthropology, and cognitive science plus many others. Generally, behavior science deals primarily with human action and often seeks to generalize about human behavior as it relates to society. 
The term behavioral sciences is often confused with the term social sciences.Or even engineering sciences Though these two broad areas are interrelated and study systematic processes of behavior, they differ on their level of scientific analysis of various dimensions of behavior.
Behavioral 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, social neuroscience ethology, and cognitive science.
In contrast, social sciences provide a perceptive framework to study the processes of a social system through impacts of social organisation on structural adjustment of the individual and of groups. They typically include fields like sociology, economics, public health, anthropology, demography and political science.
Many subfields of these disciplines cross the boundaries between behavioral and social sciences. For example, political psychology and behavioral economics use behavioral approaches, despite the predominant focus on systemic and institutional factors in the broader fields of political science and economics.
Behavioural sciences includes two broad categories: neural -- Information sciences and social -- Relational sciences.
Information processing sciences deals with information processing of stimuli from the social environment by cognitive entities in order to engage in decision making, social judgment and social perception for individual functioning and survival of organism in a social environment. These include psychology, cognitive science, psychobiology, neural networks, social cognition, social psychology, semantic networks, ethology, and social neuroscience.
On the other hand, Relational sciences deals with relationships, interaction, communication networks, associations and relational strategies or dynamics between organisms or cognitive entities in a social system. These include fields like sociological social psychology, social networks, dynamic network analysis, agent-based model and microsimulation.
Insights from several pure disciplines across behavioural sciences are explored by various applied disciplines and practiced in the context of everyday life and business. These applied disciplines of behavioural science include: organizational behavior, operations research, consumer behaviour and media psychology.
