15. Industrial-organizational psychology 
Industrial-organizational psychology takes place in the workplace. It's the study of how 
employees feel influenced or motivated at work, how employers can increase the productivity of 
their team, the ways companies may be able to retain employees and increase their job 
satisfaction. Many businesses use industrial-organizational psychologists to develop tests that 
serve as a screening tool for specific positions within the company. 
16. Military psychology 
Military psychologists work in military settings and with military personnel to provide services 
like therapy for mental illness. They may also acclimate soldiers to civilian life and help those in 
the military handle stress. Many military psychologists assist with the development of recruiting 
strategies and help leaders understand how to motivate soldiers and work with those who may be 
experiencing emotional distress. 
17. Neuropsychology 
Neuropsychology is the study of the brain and how it affects our behaviors and psychological 
thoughts. A neuropsychologist may work with patients who have experienced a brain injury or 
illness, like a stroke or dementia, to understand how their diagnosis impacts their behavior. They 
may also work with other health care professionals to develop treatment plans. 
18. Personality psychology 
Personality psychology is the study of an individual's personality and how it can affect their 
behavior. These psychologists may seek to understand what factors, if any, influence the 
personalities we have, how our personalities may affect our decision-making skills and if there 
are personality traits that are connected to specific disorders. 
19. Psychometric psychology 
The field of psychometric psychology focuses on developing psychological tests and assisting in 
their administration to specific people or groups. These tests can be helpful for understanding 
employees, customers, patients or children.
