That is the field I will be pursuing after graduation. Industrial and Organizational psychology mainly deals with selection and assessment of potential or existing employees within a corporation. Organizational development of a corporation is another part of Industrial psychology. This includes employee attitude surveys, diversity management training, and organizational analysis and evaluation. This is when you analyze potential or existing programs to find out if they are beneficial to the corporation in regards to cost and benefits.
Clinical psychology is another main field of psychology.
One issue many people find confusing about clinical psychology is the difference between a psychologist and a psychiatrist. A psychologist cannot prescribe medication to the patient and is more likely to use a cognitive approach in helping a patient. Some psychologists treat individuals with mental disorders and abnormal behavior. Those who do this are usually called clinical or counseling psychologists. To be a practicing clinical or counseling psychologist, you need to have a doctoral degree plus proper licensing.
