Psychology is a scientific field focusing on the mind and behavior. It is a relatively new science, with most of the advancement and contributions to this arena occurring within the past 150 to 200 years. When psychology first became a widely studied field, psychologists spent their time looking for cause and effect relationships, to ascertain the underlying mental processes involved in behavior.
Today, psychology still uses a cause-and-effect approach, but psychologists now understand that many factors influence behavior. If you choose to study psychology, you will have the option of exploring a number of subfields within psychology.
