Document Summary
Motives needs, and wants, desires leading to goal-directed behaviour. Humans like to be in balance; we want balance. If we get imbalance (stress), we want to cope with it: hungry (imbalance), motivates you to get food to eat. Drive motivates to engage in activities that reduce the tension. Whether or not to pursue a goal . External goal that motivates your behaviour (i. e. ice cream, juicy steak, a on an exam) Environmental factors; not very much on biological bases of human motivation. All behaviour is driven because we want to reproduce. Note: there are two types of motives: biological and social. Paraventricular nucleus: contains neurons that respond to hunger and thirst signals, large role in modulation of hunger, neuropeptide y and serotonin play important roles and some others. Glucostatic theory: measures sugar level; brain will monitor glucose levels and signal to eat, hunger is regulated by rise and fall of glucose levels.
