Personality psychologist (source code)

= Personality psychologist

A <personality psychologist> studies relatively persistent patterns of <behavior>, <emotion> and <cognition>, together with differences between people and variation across situations. Repeated observations help distinguish a stable tendency from a response to one unusual setting. Comparing <self-report> with observed <behavior> can test whether a trait measure predicts more than another report using the same method. Stability does not imply that <behavior> is identical in every context. <APA Dictionary of Psychology by the American Psychological Association>[personality psychology entry]{ref}
