Ch7. Motivation Theories — Content, Process, and Reinforcement Theories

Content Theories

Maslow's Hierarchy of Needs:
Physiological → Safety → Social (Belonging) → Esteem → Self-Actualization
Lower needs must be satisfied before higher needs motivate behavior.

Herzberg's Two-Factor Theory:
Hygiene Factors:  Prevent dissatisfaction (salary, working conditions, job security)
Motivator Factors: Create satisfaction (achievement, recognition, responsibility, growth)
→ Satisfying hygiene factors does NOT motivate — only motivators do.

Alderfer's ERG Theory:
Existence · Relatedness · Growth
Regression possible: frustration at higher levels can reactivate lower-level needs.

McGregor's Theory X and Theory Y:
Theory X: People are inherently lazy; need control and direction
Theory Y: People are self-directed and seek responsibility and self-actualization
→ Theory Y reflects the modern management perspective

Process Theories

Vroom's Expectancy Theory:
Motivation = Expectancy × Instrumentality × Valence

Expectancy:       Belief that effort will lead to performance
Instrumentality:  Belief that performance will lead to reward
Valence:          Personal value placed on the reward

Adams' Equity Theory:
Compares one's own input/output ratio to a reference person's
Perceived inequity → discomfort → behavioral adjustment
(reduce inputs, increase outputs, change the reference, or leave)

Goal-Setting Theory (Locke):
Specific, challenging goals → higher performance
Requires goal acceptance and feedback
SMART Goals: Specific · Measurable · Achievable · Relevant · Time-bound

Reinforcement Theory

Reinforcement Theory (Skinner):
Behavior is shaped by its consequences.

Positive Reinforcement:
Desired behavior + reward → behavior repeats

Negative Reinforcement:
Removal of an aversive stimulus → behavior repeats
(Example: completing work on time to avoid a manager's follow-up)

Punishment:
Undesired behavior + aversive consequence → behavior suppressed

Extinction:
Removing rewards → behavior fades over time

Reinforcement Schedules:
Fixed-Interval:    After a set time (weekly paycheck)
Fixed-Ratio:       After a set number of behaviors (per-unit commission)
Variable-Interval: After unpredictable time intervals
Variable-Ratio:    After unpredictable number of behaviors
Variable-Ratio = Most powerful (principle behind gambling and social media)

Key Concept Cards

Maslow: Physiological → Safety → Social → Esteem → Self-Actualization ★★★★★ : Lower-order needs must be met before higher-order needs become motivating. Memory tip: Physical, Safety, Social, Esteem, Self-Actualization

Herzberg: Salary = Hygiene, Not Motivation ★★★★★ : Raising pay prevents dissatisfaction but does not motivate. Achievement and recognition are the true motivators. Memory tip: Salary = hygiene only

Expectancy Theory: E × I × V ★★★★☆ : Expectancy × Instrumentality × Valence. All three must be non-zero for motivation to exist. Memory tip: Effort → Performance → Reward → Value

Practice Quiz

Q. When does Vroom’s Expectancy Theory predict that motivation equals zero?

If any one of the three components equals zero, total motivation equals zero. Expectancy = 0: The employee believes that no matter how hard they try, they cannot achieve the required performance. Instrumentality = 0: The employee doubts that good performance will actually lead to a reward. Valence = 0: The reward offered holds no personal value for the employee. Practical implication: HR must ensure the performance-reward link is credible and visible, and that rewards are tailored to what individual employees actually value.

Q. Why is a variable-ratio reinforcement schedule the most powerful?

Because the reward is unpredictable — the individual never knows exactly when the next reward will come — they persist longer and are most resistant to extinction when rewards stop. This is the same mechanism behind gambling and social media “likes.” In HR, surprise recognition awards or spontaneous spot bonuses leverage this principle. A fixed-ratio schedule (e.g., commission per sale) is predictable and strong, but variable-ratio produces the most sustained behavior because the anticipation itself becomes part of the motivation.
