When To Use

What is psychology?

Psychology is the study of the mind, mental processes, and behaviors of humans and animals.The term psychology is used to describe many specific areas of study. Generally, psychology is interested in the brain and, more specifically, why we think the way we do.Because the mind is so complex, psychology is a very wide field with many subdivisions and branches of study. A few of the major areas of psychology include:

• clinical psychology, which involves diagnosing and treating personality and behavior disorders;



• cognitive psychology, which studies mental processes such as memory, language, and perception; and



• developmental psychology, which studies how our mental processes change as we age and experience more of life.

Both psychiatry and neuroscience are often confused with psychology. Like psychology, psychiatry also diagnoses and treats mental disorders but treatments are different. A psychiatrist is a medical doctor who can prescribe medicine for mental illnesses. A psychologist doesn’t often have a medical degree and instead treats patients with counseling and therapy, a process known as psychotherapy.On the other hand, neuroscience is focused on the actual neurons, tissues, and synapses that physically make up the brain as an organ, rather than with how we think about things, as psychology is.Even if they don’t know the specifics, most people are aware that psychology is a study of the mind and thinking. For this reason, the word psychology is often used to refer generally to a person’s thought process or mental state, as in In order to really know what happens during war, you need to understand a soldier’s psychology.
