Psychology is both an applied and academic field that studies the human mind and behavior. Research in psychology seeks to understand and explain how we think, act and feel. As most people already realize, a large part of psychology is devoted to the diagnosis and treatment of mental health issues, but that///'s just the tip of the iceberg when it comes to applications for psychology. In addition to mental health, psychology can be applied to a variety of issues that impact health and daily life including performance enhancement, self-help, ergonomics, motivation, productivity, and much more.
