The brain is an incredible organ and probably one of the most complex structures around. Earning an associate degree focused on psychology can help you unravel the mysteries of the brain. Once you have the basics down from Introduction to Psychology, your options are endless. Learn how the brain developes throughout your entire life, or focus on specific times such as childhood, adolescence or adulthood. If more complex issues about the brain interest you, you may want to take a course in abnormal psychology, and business majors may be interested in taking industrial/organizational psychology.
