Instincts- specific, inborn behavior patterns characteristic of an entire species. Critique- na ve-not everybody is trying to be the best person they can be. Intrinsic motivation- desire to perform a behavior that stems from behavior performed (sports, video games) Extrinsic motivation- desire to perform a behavior to obtain an external reward or avoid punishment.
