Document Summary
Psya02 lecture 8 sex & eating. Biological influences: hypothalamic centers in the brain monitoring appetite, appetite hormones, stomach pangs, weight set/ settling point, attraction to sweet and salty tastes, adaptive wariness toward novel foods. Psychological influences: sight and smell of food, variety of foods available, memory of time elapsed since last meal, stress and mood, food unit size. Social-cultural influences: culturally learned taste preferences, responses to cultural preferences for appearance. Stomach contractions (pangs) send signals to the brain making us aware of our hunger. A feedback system between eating and insulin levels maintains homeostatic control of nutrition. Memory plays an important role in hunger. Due to difficulties with retention, amnesia patients eat frequently if given food. (rozin et al. , 1998) Suggests that part of knowing when to eat is our memory of our last meal. Body chemistry and environmental factors influence not only when we feel hunger but what we feel hungry for.
