Psychology is the study of human and animal behavior (normal and abnormal) and the psychological, social, and biological processes related to that behavior. Psychology has three main facets. It is a discipline: a major focus of study most often in colleges and universities. It is also a science: methods of conducting research, quantitative and qualitative analyses of data, and understanding and interpreting research findings. Psychology is also a profession: a calling that requires one to apply special knowledge, abilities, and skills in an effort to solve many individual and societal concerns and problems.
