Document Summary

Motivation: concerns the physiological and psychological processes underlying the initiation of behaviours that direct organisms toward specific goals. Initiating factors, motives, include the thoughts feelings and sensations and bodily processes that lead to goal directed behaviour. Drive: a 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. When a drive is satisfied, the reward centres in our brains become activated. Homeostasis: the body"s physiological processes that allow it to maintain consistent internal states in response to the outer environmental. Mechanisms in our brain that take note of these changes in energy consumption and predict how much food should be consumed to account for this increased need for energy. Motivation is not only influenced by current needs, but also by the anticipation of future needs, process known as allostasis.
