Motivation: concerns the physiological and psychological processes underlying the initiation of behaviours that direct organisms toward specific goals. Drive: biological trigger that tells us we may be deprived of something and causes us to seek out what is needed, such as food or water. Homeostasis: body"s physiological processes that allow it to maintain consistent internal states in response to the outer environment: needing more food to keep your energy up when you are stressed. Allostasis: motivation is not only influenced by current needs, but also by the anticipation of future needs. Glucose: sugar that serves as a primary energy source for the brain and the rest of the body. Satiation: point in a meal when we are no longer motivated to eat: caused by cholecystokinin, cck. Unit bias: tendency to assume that the unit of sale or portioning is an appropriate amount to consume: the never-ending soup bowl.
