Motivation derived from the Latin word movere, meaning to move. Motivation is defined as “an inferred process in a person or animal that causes movement either toward a goal or away from an unpleasant situation.” (Wade Tavris Garry, 421) Motivation takes many forms. There are, however, four main areas of human motivation: food, love, sex, and achievement. The human mind is designed with the innate ability to achieve anything. The interesting part is how we all use different triggers and motivators to get us going. These motivations then generate search behavior to meet these needs and desires. Say no to plagiarism.

Get an original essay While reading Psychology 11th Edition by Wade, Tarvis and Garry, I realized that there are two classes of factors that influence a person's motivation. ; intrinsic factors and extrinsic factors. Intrinsic factors are also called motivators and are linked to satisfaction. Extrinsic factors are hygiene factors and are linked to dissatisfaction. Motivation factors lead to satisfaction because a need for growth and fulfillment and hygiene factors lead to dissatisfaction because unpleasantness must be avoided. Motivation can also take four main forms, as mentioned earlier. The first being food, which, if available, the hypothalamus receives information about hunger hormone levels. There are many triggers that cause you to eat, besides the sight and smell of food, stress can increase the production of ghrelin, which increases your appetite. The second form is love. We are motivated to attract or please a person with whom we are in a relationship. The brain releases dopamine, a neurotransmitter essential for rewarding motivated behavior. For example, by successfully attracting our partner, this is released. The third form is sex. There are 4 stages in the sexual response cycle: desire, arousal (excitement), orgasm and resolution. Leonore Tiefer – sex researcher and therapist – states that for humans, “sex is not a natural act, sex is more like dancing than digestion, something that happens learning rather than a simple physiological process.” Sociocultural influences have also been shown to affect sexual motivation, particularly in women. The final area is achievement, this is an individual's need to achieve realistic goals, receive feedback, and experience a sense of accomplishment. Another interesting point of this book is the humanist theory of Abraham Maslow. His theory concluded that human motivation is based on a hierarchy of needs. He identified that there is a hierarchical relationship between a person's different needs and the basic needs that must be met before higher levels of needs can act as behavioral motivators. Different people from different cultural backgrounds and in different situations may also have different hierarchies of needs. The core of this theory is that when a need is satisfied, its strength decreases and the strength of the next level increases. He is the opposite of Sigmund Freud. Freudian theory of motivation suggests that unconscious psychological forces, such as hidden desires and motivations, shape an individual's behavior. According to Freud, most human behavior is the result of desires, impulses.
