Maslow's Theory says that he believes that humans strive for an upper level of capabilities and humans seek the limit of creativity, the highest level of consciousness and wisdom. Maslow has set up a hierarchic theory of needs. All of his basic needs are instinctual, equivalent of instincts in animals. Humans start with a very weak outlook that is then shaped as the person grows. If the environment is right, people will grow straight and beautiful, realizing the potentials they have inherited. If the environment is not "right" they will not grow tall and straight and beautiful. One must satisfy lower level basic needs before progressing onto meeting the higher-level growth needs. Once these needs have been reasonably satisfied they may be able to reach the highest-level called self-actualization. The steps of this pyramid starting from the bottom include: Physiological needs, Safety needs, Belonging needs, Esteem needs and finally Self-actualization. I agree with him on the his pyramid because I think that you can not go on to the next subject or "level" until the one you are currently on is completed. Different people have different levels of completeness.
Rokeach's Theory was about open and closed mindedness about beliefs, attitudes and values. He had a system that he followed about beliefs, attitudes and values that were as follows: Beliefs vary in centrality: the more central, the more resistant to change. Change in central Beliefs lead to overall change in belief system. Changes in peripheral Beliefs lead to less change in overall system. Value is the most important conception in understanding behavior. Values have two functions: Instrumental (day to day) and Terminal (ultimate aims).
