Pre-lecture discussion: why are you here? (as in what did you wake up today to attend class) --> but actually all motives involve more of both. Need (e. g. food, water) ---> drive (hunger, thirst) ---> drive-reducing behaviors (eating, drinking) Calling your parents to make them happy. Increase in ghrelin (hormone that produced in stomach lining when empty) Bypass surgery (which connects a smaller pouch of the stomach directly to the small intestine) to reduce stomach lining in diabetic people as a drastic measure. But, even without a stomach (through surgery, etc), hunger still exists. When stimulated, animals would eat less or more slowly. V = voracious and very large [see hyperphagic rat] Presence of eating cues (marketers harness this) The tendency to maintain a balanced or constant internal state. Genetics (and history) determine a stable weight. R = 0. 74 mz twins reared apart (genetically identical twins and correlation to genetic factors)
