Behavior is what we infer motivation with. This could be any activity. Performance is some kind of evaluation of behavior judged against a standard. Ability is a determinant of behavior. It can be very broad or narrow.
Situational constraints are another determinant of behavior.

This theory states that lower order needs have to be met, such as food and shelter before higher order needs such as friendships are met. Self-esteem needs . . .
