According to vroom's model, which psychological force answers the question, "how great a reward will there be if my performance is exemplary? "

I believe the correct answer is: Valence.

According to Vroom's model of expectancy theory, the psychological force which answers the question: "how great a reward will there be if my performance is exemplary?” or “"How serious a punishment do i expect if i under-perform?" is: valence.

Vroom defines valence as “one-dimensional value assigned to an object, situation, or state that can usually be positive or negative”. Valence represents the importance that the individual places on the expected outcome of a situation.
