Document Summary
Motives needs, wants, desires leading to goal-directed behaviour. We behave because we are motivated to behave because of imbalances. We can explain things through achievement and success. Need to belong, need to connect (in order to mate and survive) People are motivated by a wide range of needs, which can be divided into two broad classes: biological motives and social motives. The list on the left (adapted from madsen, 1973) shows some important biological motives in humans. The list on the right (adapted from murray, 1938) provides examples of prominent social motives in humans. The distinction between biological and social motives is not absolute. Lateral(on) and ventromedial hypothalamus (front base of the brain) involved in regulating hunger. Arcuate nucleus neurons (brain cells) use neurotransmitters to communicate messages to each other (hormones) neuropetide y, serotonin, and ghrelin in stomach. Glucostatic (blood sugar) theory decrease in blood sugar= hunger. Insulin(pancreas) increase =hungry and leptin (fat cells) increase in leptin = satisfied.
