The field of psychology can be defined as the science of the mind. Psychology encompasses the methods and processes through which psychologists study the mind. Psychology is also defined as the scientific study of the way people behave, think and feel.
Since psychology is classified as a social science and is defined as the science of the mind, the data that is collected and analyzed is data on human behavior. Psychologists then interpret this data to form theories, methods and techniques for altering those behaviors. Since the mind is such a complex organic machine, the field of psychology has many branches, including clinical, cognitive, developmental, evolutionary, forensic, health, neuropsychology, occupational and social psychology. The goal of each of these branches is to determine how the mind works and how it directs behavior. Each of these branches relies on scientific methods, experiments, and quantitative and qualitative data.
