What is the idea around evolutionary approach?
Instinct that requires a sign stimulus. Focus on sexual behaviors and competition.
Instinct

Sign stimulus
Something in the environment that turns on a fixed pattern of behavior.
Drive Reduction Theory
Another way to think about motivation is through the constructs of drive and need. As a drive become stronger, we are motivated to reduce it. The goal is homeostasis.
Drive
An aroused state that occurs because of a physiological need.
Need
A deprivation that energizes the drive to eliminate or reduce the deprivation.
Homeostasis
The body’s tendency to maintain an equilibrium, or a steady state or balance.
Optimum Arousal Theory
Suggests that there should be a level of arousal that is ideal for facilitating goal attainment.
Arousal
Feelings of being alert or engaged.
Yerkes-Dodson Law
