What shapes individual behaviour
Biology, psychology and environment, acting together.
Can two people with the same skills react differently to the same deadline?
Behaviour depends on the person and the situation together: biological, psychological and environmental factors.
Two probationary officers join the same public-sector bank branch on the same day, after the same training. At the first quarter-end, one treats the deposit target as a game to win; the other is anxious for weeks. Same job, same rules, different behaviour.
In plain wordsIndividual behaviour is what a person does, says and feels at work, and the reasons behind it.
Exam definitionA standard textbook definition: individual behaviour is the way a person acts, thinks and responds, shaped by internal traits, learned experience and the surroundings.
Understanding it helps a manager explain people's reactions, and improve how the organisation works. Kurt Lewin put the idea as a formula in 1936:
Neither part works alone. The same person behaves differently in a different setting, and the same setting draws different behaviour from different people. The factors fall into three groups.
| Factor | What it includes | At work |
|---|---|---|
| Biological | Age, gender, health, heredity | Physical and emotional abilities; adaptability and handling of stress may vary. |
| Psychological | Personality, perception, attitude, beliefs | An optimistic employee may see a deadline as a challenge rather than a threat. |
| Environmental | Culture, family, peers, workplace | Collectivist cultures stress teamwork; individualist cultures stress personal success. |
Back to the bank branch. The two officers are of the same age and in good health, so biology explains little here. Psychology explains more: the first officer is optimistic and sees the target as a challenge. The environment adds the rest: perhaps she grew up in a family business where targets were dinner-table talk. Both work under the same branch manager, whose style also shapes them.
Don't confuse behaviour with personality. Personality is the stable pattern of traits a person carries; it is one psychological factor. Behaviour is what the person actually does in a given situation, and it depends on the setting too.
Where it breaks. The three groups act together, so their effects can rarely be separated. Factors that are easy to see, such as age and gender, tempt managers to stereotype; reviews of the research find few consistent differences between men and women in job performance. Culture labels such as "collectivist" describe averages across a country, not any one person.
In practice. A manager cannot change a person's heredity or upbringing, but can change the environment: the job, the team, the targets and the rewards. So the useful question is which part of the situation to change.
For exams. Know the three groups of factors with their examples, and Lewin's B = f(P, E). Individualism and collectivism come from Hofstede's work, covered in Workforce Diversity and Cross-Cultural Behaviour.
1. Culture, family, peers and the workplace are which kind of factor?
Not quite. The answer is “Environmental”. They are the person's surroundings, so they are environmental. Personality and perception are psychological; age, gender, health and heredity are biological.
2. Two new officers with the same training work in the same branch under the same manager. One sees the quarter-end target as a challenge, the other as a threat. What best explains the difference?
Not quite. The answer is “Psychological factors, such as optimism”. They share the same branch and manager, so the environment explains little of the difference. How each one sees the target is a matter of personality and perception, which are psychological.
3. What does Lewin's formula B = f(P, E) imply for a manager?
Not quite. The answer is “The same person may behave differently if the situation changes”. Behaviour depends on the person and the environment together. "Fixed by personality alone" ignores the E in the formula, and the environment is the part a manager can change.
“Which of the three factors has shaped your own behaviour at work or study the most?”

- Lewin: B = f(P, E). Behaviour depends on the person and the environment together.
- Biological: age, gender, health, heredity.
- Psychological: personality, perception, attitude, beliefs.
- Environmental: culture, family, peers, workplace. Collectivist cultures stress teamwork; individualist ones, personal success.
