Two important personality theories are the biological theory and the humanistic theory. The biological theory is based on the premise that all people inherit their characteristics from their family. This theory basically contends that people do not have control over their behaviors because they are genetically pre-determined. The humanistic theory, on the other hand, is based on the premise that each person has free will to control their actions. This theory does not go along with the idea that behaviors are pre-determined by genetics, but chosen by the individual. These two theories have created debates between psychologists for many yearsHans j. Eysenck, Ph. D., D.Sc., who developed the biological theory, is one of the world's most cited psychologist. He is a pioneer in the use of behavior therapy as well as research in personality theory and measurements. The biological theory has to do with his findings that individual differences in personality are biology based.

Maslow's hierarchy of needs: Self-actualisation, S...This was based on his theory that there are three dimensions of personality (super factors). These dimensions of personality were extraversion-introversion, neuroticism, and psychoticism. Eysenck also went a step farther in pointing out the results of many studies indicating that genetics play an important role in deciding the amounts of which of the three personality dimensions one might possess. I agree with this theory because even most psychologists will admit that it is getting increasingly harder to ignore the obvious link between our genetic makeup and certain inherited behaviors. I disagree with this theory because it is difficult to test in actual experiments. Another reason I disagree with this theory is that while genetics play a role in certain behaviors, it does not excuse or justify certain actions. Lastly, this theory offers us very little in the area of personality change.
