Motivation

Motivation refers to the forces within an individual that affect the direction, intensity and persistence of voluntary behaviour. Theories of motivation are based in interpretations of human needs, which then result in behaviours to meet those needs. In general, motivation is considered to be what drives an individual to meet a particular goal, be it to resolve negative situations or for additional reward.

Theories of motivation are used in practice within the fields of sports psychology to achieve set goals, and more recently within human resources departments in businesses in order to improve the productivity, commitment and retention of staff.

Studies on motivation make a distinction between needs and drives. Needs are deficiences (physiological or psychological) that may trigger a voluntary behavior to reduce those deficiencies or satisfy those needs. Drives have been defined as instinctive tendencies to seek particular goals, or maintain internal stability.

Motivational theory originates from Abraham Maslow's hierarchy of needs, developed in the 1940's. Although use of the needs hierachy has been widespread in many fields since publication, further developments in motivational psychology act to address criticisms and assumptions in Maslow's original theory.

Maslow’s Needs Hierarchy

Developed in the 1940's, Abraham Maslow's needs hierarchy is at the basis of studies into motivation and is the most well-known. However, this theory has not found much scientific support.

Maslow's approach to need fulfillment is to place the human needs into a hierarchy of five basic categories: physiological, safety, belongingness, esteem, and self-actualisation. The theory posits that while we are motivated by several needs simultaneously, the strongest motivator will be the lowest unsatisfied needs at the time. Once these lower-level needs are satisfied, the individual would then be motivated to fulfil the next level of needs in the hierarchy, and would continue to be so, even if this was never fulfilled.

Subsequent theories of motivation sought to address criticisms of this theory, however it has continued to be very influential.

ERG Theory

ERG theory recategorised Maslow's needs hierachy into three basic needs: existence, relatedness and growth.

Existence needs address physiological concerns, such as hunger, shelter and self-defence. Relatedness addresses social concerns, such as developing networks and identifying with social groups. Growth needs, in this theory reached when existence and relatedness were already addressed, include further learning and self-actualisation.

The main development of the ERG theory from Maslow was that whilst the individual would continue to develop higher needs once lower needs were met, they could also regress back to needing to being motivated by their lower needs if unable to fulfil higher ones..

Theory of Learned Needs

David McLelland developed his theorory of learned needs based on the concept that needs can be strengthened through reinforcement. His research found that there are three learned needs: achievement, power and affiliation.

• Need for Achievement (nAch)

Individuals with a high nAch seek to achieve reasonably challenging goals through their own efforts, such as succeeding in competitions. They also desire clear feedback and recognition for their work. Money is a weak motivator for high nAch individuals. In contrast, individuals with a low nAch score perform better when money is used as an incentive.

• Need for Affiliation (nAff)

A high nAff score indicates that the individual is strongly motivated by approval from others, meeting external expectations, and avoiding conflict and confrontation. In practical terms, they serve as good mediators and in building long-term relationships. However, it has been found that individuals with a low nAff are more suitable for decision-making positions as their choices and actions in allocating resources are not biased by a personal desire to avoid conflict or to earn approval.

• Need for Power (nPow)

People with a high nPow seek to exercise control over other individuals, and aim to gain and maintain leadership positions. There are two types of nPow: personalised power, in which individuals want to attain power for its own sake and for status, and socialised power, where the desire for power is in order to use it to help others.
