There are many fascinating issues that biopsychologists are dealing with today. For example, the question of localization of function asks whether each physical part of the brain is responsible for performing a specific job, or if the brain works as a whole using all of its parts to do every job. Along those same lines, there is the question of the mind-body problem. Many psychologists are asking how mental and physical events interact. Many biopsychologists are specially trained in areas that deal with the study of the brain itself.
Psychology is divided up into different areas that psychologists often call perspectives.
The number and names of these perspectives differ depending on who you ask, but there are certain major ones that stand out. For example, there are behavioural psychologists who think that behaviour is learned. They think that human and animal minds work like machines which, given a certain input, give a certain output. There are also cognitive psychologists who think that behaviour is a result of information processing, like that of a computer. The brain is the structure of the computer and the mind runs software in the brain.
