Drive Reduction Theories

There are a number of drive theories. The Drive Reduction Theory grows out of the concept that we have certain biological needs, such as hunger. As time passes the strength of the drive increases as it is not satisfied. Then as we satisfy that drive by fulfilling its desire, such as eating, the drive's strength is reduced. It is based on the theories of Freud and the idea of feedback control systems, such as a thermostat.

There are several problems, however, that leave the validity of the Drive Reduction Theory open for debate. The first problem is that it does not explain how Secondary Reinforcers reduce drive. For example, money does not satisfy any biological or psychological need but reduces drive on a regular basis through a pay check second-order conditioning. Secondly, if the drive reduction theory held true we ould not be able to explain how a hungry human being can prepare a meal without eating the food before they finished cooking it.

However, when comparing this to a real life situation such as preparing food, one does get hungrier as the food is being made (drive increases), and after the food has been consumed the drive decreases. The only reason the food does not get eaten before is the human element of restraint and has nothing to do with drive theory. Also, the food will either be nicer after it is cooked, or it wont be edible at all before it is cooked.

Cognitive dissonance theory

Main article: Cognitive dissonance

Suggested by Leon Festinger, this occurs when an individual experiences some degree of discomfort resulting from an incompatibility between two cognitions. For example, a consumer may seek to reassure himself regarding a purchase, feeling that another decision may have been, in retrospect, preferable.

Another example of cognitive dissonance is when a belief and a behavior are in conflict. A person may believe smoking is bad for one's health and yet continues to smoke.

Affective-Arousal Theories

Need Achievement Theory

David McClelland’s achievement motivation theory envisages that a person has need for three things but people differ in degree in which the various needs influence their behavior: Need for achievement, Need for power, and Need for affiliation

Main article: Achievement motivation

Interests Theory

Generally people will do what interests them. If a person has a very strong interest in one an area then obtaining outcomes in that area will be very strongly reinforcing relative to obtaining outcomes in areas of weak interest. Holland Codes are used in the assessment of interests as in Vocational Preference Inventory (VPI; Holland, 1985).

Need Theories

Need Hierarchy Theory

Abraham Maslow's hierarchy of human needs theory is the most widely discussed theory of motivation. The theory can be summarized as thus:

• Human beings have wants and desires which influence their behaviour; only unsatisfied needs can influence behavior, satisfied needs cannot.
• Since needs are many, they are arranged in order of importance, from the basic to the complex.
• The person advances to the next level of needs only after the lower level need is at least minimally satisfied.
• The further the progress up the hierarchy, the more individuality, humanness and psychological health a person will show.

The needs, listed from basic (lowest, earliest) to most complex (highest, latest) are as follows:

• Physiological
• Safety and security
• Social
• Self esteem
• Self actualization

Herzberg’s two factor theory

Frederick Herzberg's two factor theory, concludes that certain factors in the workplace result in job satisfaction, while others do not, but if absent lead to dissatisfaction.

He distinguished between:

• Motivators; (e.g. challenging work, recognition, responsibility) which give positive satisfaction, and
• Hygiene factors; (e.g. status, job security, salary and fringe benefits) which do not motivate if present, but if absent will result in demotivation.

The name Hygiene factors is used because, like hygiene, the presence will not make you healthier, but absence can cause health deterioration.

The theory is sometimes called the "Motivator-Hygiene Theory."

Alderfer’s ERG theory

Created by Clayton Alderfer, Maslow's hierarchy of needs was expanded, leading to his ERG theory (existence, relatedness and growth). Physiological and safety, the lower order needs, are placed in the existence category, Love and self esteem needs in the relatedness category. The growth category contained the self actualization and self esteem needs.

Self-determination theory

Self-determination theory, developed by Edward Deci and Richard Ryan, focuses on the importance of intrinsic motivation in driving human behavior. Like Maslow's hierarchical theory and others that built on it, SDT posits a natural tendency personal growth and development. Unlike these other theories, however, SDT does not include any sort of "autopilot" for achievement, but instead requires active encouragement from the environment. The primary factors that encourage motivation and development are autonomy, competence feedback, and relatedness.

Cognitive theories

Goal-setting theory

Goal-setting theory is based on the notion that individuals sometimes have a drive to reach a clearly defined end state. Often, this end state is a reward in itself. A goal's efficiency is affected by three features; proximity, difficulty and specificity. An ideal goal should present a situation where the time between the initiation of behavior and the end state is close in time. This explains why some children are more motivated to learn how to ride a bike than mastering algebra. A goal should be moderate, not too hard or too easy to complete. In both cases, most people are not optimally motivated, as many want a challenge (which assumes some kind of insecurity of success). At the same time people want to feel that there is a substantial probability that they will succeed. Specificity concerns the description of the goal in their class. The goal should be objectively defined and intelligible for the individual. A classic example of a poorly specified goal is to get the highest possible grade. Most children have no idea how much effort they need to reach that goal. For further reading, see Locke and Latham (2002).

Psychoanalytic theories of motivation

Some psychologists believe that a significant portion of human behavior is energized and directed by unconscious motives. According to Maslow: "Psychoanalysis has often demonstrated that the relationship between a conscious desire and the ultimate unconscious aim that underlies it need not be at all direct ." In other words, stated motives do not always match those inferred by skilled observers. For example, it is possible that a person can be accident-prone because he has an unconscious desire to hurt himself and not because he is careless or ignorant of the safety rules. Similarly, some overweight people are not really hungry for food but for attention and love. Eating is merely a defensive reaction to lack of attention. Some workers damage more equipment than others because they harbor unconscious feelings of aggression toward authority figures.

Psychotherapists point out that some behavior is so automatic that the reasons for it are not available in the individual's conscious mind. Compulsive cigarette smoking is an example. Sometimes maintaining self-esteem is so important and the motive for an activity is so threatening that it is simply not recognized and, in fact, may be disguised or repressed. Rationalization, or "explaining away", is one such disguise, or defense mechanism, as it is called. Another is projecting or attributing one's own faults to others. "I feel I am to blame", becomes "It is her fault; she is selfish". Repression of powerful but socially unacceptable motives may result in outward behavior that is the opposite of the repressed tendencies. An example of this would be the employee who hates his boss but overworks himself on the job to show that he holds him in high regard.

Unconscious motives add to the hazards of interpreting human behavior and, to the extent that they are present, complicate the life of the administrator. On the other hand, knowledge that unconscious motives exist can lead to a more careful assessment of behavioral problems. Although few contemporary psychologists deny the existence of unconscious factors, many do believe that these are activated only in times of anxiety and stress, and that in the ordinary course of events, human behavior — from the subject's point of view — is rationally purposeful.
