Document Summary
Arousal is a general term that can encompass many things: changes to our autonomic nervous system, etc. Whatever motivates behavior and helps us do what we want to be satisfied. As we get hungrier, our arousal gets higher, and we get motivated to get our food. This is maslow"s hierarchy, which is very popular and seems to sum up things very well. It is not only our internal drives that guide our behavior: we eat when a food tastes good! Cultural beliefs and personal experience are really important in determining what kind of foods we eat. We like sweet things, we avoid bitter things - because lots of poisons and things we don"t eat are bitter. There"s no reason not to. It just has to do with cultural norms. Religious observances largely determines diet too (pork or cow). We all tend to get hungry roughly at the same times. We just associated that time with lunch time.
