HL motivational theories

McClelland's Acquired Needs Theory

A motivational theory stating that people develop three needs over time through life experiences, upbringing, and culture — nAch, nAff, and nPow — which drive their behaviour and choices

nAch (Achievement Need)

The desire to excel, achieve challenging tasks, and set/meet personal goals. People with high nAch seek success, take calculated risks, enjoy problem-solving, and are driven by accomplishment

nAff (Affiliation Need)

The desire to form positive relationships and feel happy in the workplace. People with high nAff seek approval/social interaction, avoid conflict, and prioritise harmony and collaboration

nPow (Power Need)

The desire to influence and control others or organisations. McClelland identified two types: Personal Power (controlling others) and Institutional Power (shaping organisations/systems)

McClelland — Strengths

Easy to understand and apply; recognises that people have varying needs; backed by extensive cross-cultural research; helps managers create more effective motivational strategies

McClelland — Weaknesses

Oversimplifies human behaviour; people often have a mix of all three needs; limited evidence that these three are the primary drivers of behaviour; doesn't account for personal/environmental complexity

Deci and Ryan's Self-Determination Theory

A motivational theory explaining why people do what they do, based on three basic psychological needs — Autonomy, Competence, and Relatedness — that must be met for intrinsic motivation and personal growth

Autonomy (Deci & Ryan)

The need to have control and make choices in work and personal life. Met in business by giving employees flexibility and decision-making power

Competence (Deci & Ryan)

The need to feel capable and effective in what you do, inside and outside of work. Met by providing training, development, and achievable challenges

Relatedness (Deci & Ryan)

The need to connect with others and feel a sense of belonging. Met in business through teamwork, inclusive culture, and positive workplace relationships

Deci & Ryan — Strengths

Adaptable across cultures and situations; widely applied in business, education, healthcare, and sport; backed by extensive research; recognises individual differences in motivation

Deci & Ryan — Weaknesses

Rooted in Western psychology so may not apply universally; overemphasises intrinsic motivation and downplays financial incentives; difficult to measure the three internal needs objectively

Adams' Equity Theory

A motivational theory by John Adams stating that employees compare their inputs (effort, time, commitment) to their outputs (pay, recognition, status) and want this ratio to be fair compared to colleagues

Under-reward (Equity Theory)

When an employee feels they give more than they receive compared to colleagues. Leads to frustration, dissatisfaction, and reduced effort

Equity (Equity Theory)

When an employee perceives a fair balance between their inputs and outputs compared to colleagues. Results in satisfaction and contentment

Over-reward (Equity Theory)

When an employee believes they receive more than they give. Can lead to guilt, discomfort, and a desire to restore fairness (e.g. working harder)

Restoring Equity

Employees may renegotiate terms, adjust effort levels (work more or less), or seek new opportunities where the input-output ratio feels fairer

Equity vs Equality

Equity = fairness (different pay for different skills/experience is fair). Equality = same pay for all regardless of competence (not necessarily fair). Do NOT confuse the two

Adams' Equity Theory — Strengths

Easy to understand as most people grasp fairness intuitively; recognises individual differences in perception; highlights the importance of social comparison in the workplace

Adams' Equity Theory — Weaknesses

Highly subjective — fairness is perceived differently by each person; ignores other influences like personal values and organisational culture; oversimplifies complex real-life workplace scenarios

Vroom's Expectancy Theory

A motivational theory stating that motivation depends on three factors working together: Expectancy, Instrumentality, and Valence. People choose behaviours based on expected outcomes

Expectancy (Vroom)

The belief that effort will lead to successful performance. If a worker believes hard work will result in achieving a goal, they are motivated to put in that effort

Instrumentality (Vroom)

The belief that successful performance will be rewarded. If a worker is confident that good performance leads to a desirable outcome, they are motivated to perform well

Valence (Vroom)

The value or desirability of the reward/outcome. The more appealing the outcome, the more motivated the worker is to achieve it

How Managers Use Expectancy Theory

Improve training to boost Expectancy; build trust by keeping promises to boost Instrumentality; widen reward packages to boost Valence; address the weakest component to raise overall motivation

Vroom's Expectancy Theory — Strengths

Accounts for personal differences in motivation; provides a clear, logical three-part framework; emphasises involving employees in goal-setting; flexible and applicable to many situations

Vroom's Expectancy Theory — Weaknesses

Based on subjective perceptions so cannot always accurately predict behaviour; individuals' values and perceptions vary widely; provides a framework rather than precise, testable prediction
