The duties of a cognitive psychologist vary with the work environment. In some positions, you focus primarily on the study and research of human behavior. You conduct studies that center on gaining a better understanding of perception, cognition, memory, or other brain processes for the development of algorithms to explain and predict them. You then publish your findings in a scientific journal and share them with your colleagues at conferences. Other cognitive psychologists work to diagnose and treat mental health issues in a clinical setting. You can find employment with schools where you provide counseling to students or in private practice. In some positions, you have management responsibilities that require you to supervise team members.
