Developmental psychology is primarily concerned with the changes that occur during childhood and adolescence. Topics studied range from the control of movements, the acquisition of language, math and musical abilities, the formation of the self and the identity, the formation of emotional attachments, moral judgments and the development of problem solving and reasoning skills. More recently, the time span examined and compared within developmental psychology has expanded across the lifespan and now includes in some cases the changes associated with aging, even into the elderly years. Social psychology focuses on interpersonal behavior, how people (alone or in groups) think, act, feel, believe or behave based on social situations. This includes situations where they are actually being observed and interacting with others as well as when they are isolated and the observation and interaction with others is imagined or implied. Experimental psychology traditionally encompasses a wide variety of both human and animal research concerned with the general processes of sensation, perception, learning and memory. It does not necessarily concern itself with any underlying biological, chemical or neural mechanisms which support those processes and may not address those mechanisms. Physiological psychology, however, is concerned with the underlying biologically and chemically based mechanisms underlying psychological phenomena. The emphasis on function of the nervous system and hormones is so great that the term behavioral neuroscience has largely replaced the term physiological psychology. However, there is a difference between a strict neuroscientist and a behavioral neuroscientist/physiological psychologist. A neuroscientist's primary interest in the biological or chemical mechanisms of brain function at a cellular or molecular level with often little direct interest in how these cellular or molecular functions influence larger scale phenomena such as memory or…
