Content theories are theories about the internal factors that motivate people. They typically focus on the goals that people aim to achieve and the needs, drives, and desires that influence their behavior. Content theories contrast with process theories, which examine the cognitive, emotional, and decision-making processes that underlie human motivation. Influential content theories are Maslow's hierarchy of needs, Frederick Herzberg's two-factor theory, and David McClelland's learned needs theory.

McGregor's Theory X and Theory Y Douglas McGregor proposed two different motivational theories. Managers tend to believe one or the other and treat their employees accordingly. Theory X states that employees dislike and try to avoid work, so they must be coerced into doing it. Most workers do not want responsibilities, lack ambition, and value job security more than anything else.

McGregor personally held that the more optimistic theory, Y, was more valid. This theory holds that employees can view work as natural, are creative, can be self-motivated, and appreciate responsibility. This type of thinking is popular now, with people becoming more aware of the productivity of self-empowered work teams.

ERG theory ERG Theory was introduced by Clayton Alderfer as an extension to the famous Maslow's Hierarchy of Needs. In this theory, the existence or physiological needs are at the base. These include the needs for things such as food, drink, shelter, and safety. Next come the Relatedness Needs, the need to feel connected to other individuals or a group. These needs are fulfilled by establishing and maintaining relationships.

At the top of the hierarchy are Growth Needs, the needs for personal achievement and self-actualization. If a person is continuously frustrated in trying to satisfy growth needs, relatedness needs will re-emerge. This phenomenon is known as the frustration-regression process.

Herzberg's Motivation-Hygiene theory (Two-factor theory) Frederick Herzberg felt that job satisfaction and dissatisfaction do not exist on the same continuum, but on dual scales. In other words, certain things, which Herzberg called hygiene factors, could cause a person to become unhappy with their job. These things, including pay, job security, and physical work environment, could never bring about job satisfaction. Motivating factors, on the other hand, can increase job satisfaction. Giving employees things such as a sense of recognition, responsibility, or achievement can bring satisfaction about.

Need theory David McClelland proposed a context for understanding the needs in people, which holds significance in understanding their motivations and behaviors. It is subdivided into three categories: the Need for Achievement, the Need for Affiliation, and the Need for Power.

The Need for Achievement refers to the notion of getting ahead and succeeding. The Need for Affiliation is the desire to be around people and be well received socially. It also includes the desire for being a member in a group and conformity. The Need for Power is the desire for control over others and over yourself. It confers the need to be able to exercise direction in the world surrounding you, and cause things to happen. Individuals who have high needs for achievement will tend to engage in competitive activities in order to fulfill this desire. Individuals who need to feel affiliated will tend to join clubs, groups and teams to satiate that want. Individuals who have the need for power will seek activities which likewise satisfy this need, such as, running for high positions in organizations and seeking opportunities to exercise that dominance.

This is not to say that one person cannot have needs spanning all three categories. A person may have the need for affiliation at the same time they have the need for power. While this may initially seem contradictory, there are instances where both needs can be fulfilled. Also, timing may connote different strengths of needs at different moments. So, while a person may strongly feel the need to affiliate during times of loneliness, they may at another time feel the strong need for power when instructed to organize an event. Needs may arise and change along with a change of context.

Maslow's hierarchy of needs

Content theory of human motivation includes both Abraham Maslow's hierarchy of needs and Herzberg's two-factor theory. Maslow's theory is one of the most widely discussed theories of motivation. Abraham Maslow believed that man is inherently good and argued that individuals possess a constantly growing inner drive that has great potential. The needs hierarchy system is a commonly used scheme for classifying human motives.Pardee, R. L. (1990). The basic concept behind the hierarchy system is that it's like a food pyramid. Everybody starts at the bottom of the pyramid and is motivated to satisfy each level in ascending order to work our way to the top of the pyramid, and those levels (needs) are categorized into two main groups with five different sections which are explained below. Motivation Theories of Maslow, Herzberg, McGregor & McClelland. A Literature Review of Selected Theories Dealing with Job Satisfaction and Motivation.

The American motivation psychologist Abraham H. Maslow (1954) developed the hierarchy of needs consisting of five hierarchic classes. According to Maslow, people are motivated by unsatisfied needs. The needs, listed from basic (lowest-earliest) to most complex (highest-latest) are as follows:

Physiology (hunger, thirst, sleep, etc.) Safety/Security/Shelter/Health Social/Love/Friendship Self-esteem/Recognition/Achievement Self actualization/achievement of full potential

The basic requirements build upon the first step in the pyramid: physiology. If there are deficits on this level, all behavior will be oriented to satisfy this deficit. Essentially, if a person has not slept or eaten adequately, he or she will not be interested in their self-esteem desires. Subsequently, we have the second level, which awakens a need for security. After securing those two levels, the motives shift to the social sphere, the third level. Psychological requirements comprise the fourth level, while the top of the hierarchy consists of self-realization and self-actualization.

Maslow's hierarchy of needs theory can be summarized as follows:

Human beings have wants and desires which, when unsatisfied, may influence behavior. Differing levels of importance to human life are reflected in a hierarchical structure of needs. Needs at higher levels in the hierarchy are held in abeyance until lower-level needs are at least minimally satisfied. Needs at higher levels of the hierarchy are associated with individuality, humanness, and psychological health.

Sex, Hedonism, and Evolution

One of the first influential figures to discuss the topic of hedonism was Socrates, and he did so around 470–399 BCE in ancient Greece. Hedonism, as Socrates described it, is the motivation wherein a person will behave in a manner that will maximize pleasure and minimize pain. The only instance in which a person will behave in a manner that results in more pain than pleasure is when the knowledge of the effects of the behavior is lacking. Sex is one of the pleasures people pursue.

Sex is on the first level of Maslow's hierarchy of needs. It is a necessary physiological need like air, warmth, or sleep, and if the body lacks it will not function optimally. Without the orgasm that comes with sex, a person will experience "pain," and as hedonism would predict, a person will minimize this pain by pursuing sex. That being said, sex as a basic need is different from the need for sexual intimacy, which is located on the third level in Maslow's hierarchy.

There are multiple theories for why sex is a strong motivation, and many fall under the theory of evolution. On an evolutionary level, the motivation for sex likely has to do with a species' ability to reproduce. Species that reproduce more, survive and pass on their genes. Therefore, species have a sexual desire that leads to sexual intercourse as a means to create more offspring. Without this innate motivation, a species may determine that attaining intercourse is too costly in terms of effort, energy, and danger.

In addition to sexual desire, the motivation for romantic love runs parallel in having an evolutionary function for the survival of a species. On an emotional level, romantic love satiates a psychological need for belonging. Therefore, this is another hedonistic pursuit of pleasure. From the evolutionary perspective, romantic love creates bonds with the parents of offspring. This bond will make it so that the parents will stay together and take care of and protect the offspring until it is independent. By rearing the child together, it increases the chances that the offspring will survive and pass on its genes themselves, therefore continuing the survival of the species. Without the romantic love bond, the male will pursue satiation of his sexual desire with as many mates as possible, leaving behind the female to rear the offspring by herself. Child-rearing with one parent is more difficult and provides less assurance of the offspring's survival than with two parents. Romantic love therefore solves the commitment problem of parents needing to be together; individuals that are loyal and faithful to one another will have mutual survival benefits.

Additionally, under the umbrella of evolution, is Darwin's term sexual selection. This refers to how the female selects the male for reproduction. The male is motivated to attain sex because of all the aforementioned reasons, but how he attains it can vary based on his qualities. For some females, they are motivated by the will to survive mostly, and will prefer a mate that can physically defend her, or financially provide for her (among humans). Some females are more attracted to charm, as it is an indicator of being a good loyal lover that will in turn make for a dependable child-rearing partner. Altogether, sex is a hedonistic pleasure-seeking behavior that satiates physical and psychological needs and is instinctively guided by principles of evolution.

Self-determination theory

Since the early 1970s Deci and Ryan have developed and tested their self-determination theory (SDT). SDT identifies three innate needs that, if satisfied, allow optimal function and growth: competence,White, R. W. (1963). Ego and reality in psychoanalytic theory. New York: International Universities Press. relatedness, and autonomy.deCharms, R. (1968). Personal causation. New York: Academic Press. These three psychological needs are suggested to be essential for psychological health & well-being along with behavioral motivation. There are three essential elements to the theory:

Humans are inherently proactive with their potential and at mastering their inner forces (such as drive and emotions). Humans have an inherent tendency towards growth, development, and integrated functioning. Optimal development and actions are inherent in humans but they do not happen automatically.

Within Self-Determination Theory, Deci and Ryan distinguish between four different types of extrinsic motivation, differing in their levels of perceived autonomy:

External regulation: This is the least autonomous of the four and is determined by external punishment or reward. Introjected regulation: This form of external motivation arises when the individuals have somewhat internalized regulations but do not fully accept them as their own. They may comply for self-esteem reasons or social acceptability - essentially internal reasons but externally driven. Identified regulation: This is more autonomously driven - when the individuals consciously perceive the actions as valuable.
