Document Summary
Single and multiple causes (ie; why we eat) Emotion (why motivation theorists today are interested in understanding feelings) Negative feelings can and often do undermine goal directed behaviour while positive feelings can and often do sustain goal-directed behaviour. They are inherited impulses that result in specific pattern of behaviour. We can change in order to be able to deal with environmental pressures more efficiently. Biologists use the word instinct to refer to the belief that there is an innate or biological basis for adaptive behaviour. Psychologists have largely abandoned it-didn"t help predict what will happen next. Mcdougal was important in development of initial instinct theory. Said that we are constantly going under biological structural changes as a result of environmental pressures. Principle of variation: trait variation within a population. Principle of natural selection environment selects trait that aids survival. Darwin"s contribution was not the discovery of evolution, it was that natural selection is the mechanism by which evolution occurs.
