Anthropology
Anthropology is the study of humankind (see genus Homo). It is holistic in two senses: it is concerned with all humans at all times, and with all dimensions of humanity. Central to anthropology is the concept of culture, and the notion that human nature is culture; that our species has evolved a universal capacity to conceive of the world symbolically, to teach and learn such symbols socially, and to transform the world (and ourselves) based on such symbols. 
Law
According to Western liberal political theory, a body of law attempts to balance individual rights and social control, which are viewed as being inversely related, and is enforced by a system of criminal justice. Many social scientists use the term more broadly, to refer both to formal and informal systems of social control. In most political and legal theory, however, it refers specifically to a formal system administered and enforced by a government, and more generally to include all aspects of governmental decision making and maintenance of social order.
Sociology
Sociology studies the social rules and processes that bind -- and separate -- people not only as individuals, but as members of associations, groups, and institutions.
Political Science
Political science is the study of politics. It involves the study of structure and process in government - or any equivalent system that assures safety, fairness, and closure across a broad range of risks and access to a broad range of commons for its human charges. Accordingly, political scientists often study trade unions, corporations, churches or other forms of collective intelligence that are not "political" in the sense of influencing law or executive decisions - but have structure and process approaching that of government in complexity and interconnection.
Psychology
Psychology is the science of human behavior, the mind, and mental processes in humans and animals as they interact with each other and the environment. As a practice, psychologists focus on diagnosing, assessing, and delivering preventive and therapeutic services directly to individuals.
