### Temperament
Temperament refers to the **innate, biologically based** patterns of emotional, motor, and attentional reactivity and self-regulation that appear early in life (often observable in infancy). It is largely **genetic and hereditary**, relatively stable across the lifespan, and forms the foundational "style" or "how" of an individual's behavior.
Key characteristics:
- Present from birth or very early childhood.
- Influenced primarily by biology (e.g., nervous system, neurotransmitters, genetics).
- Consistent across situations and relatively resistant to change.
- Focuses on basic emotional and behavioral tendencies, such as activity level, rhythmicity, mood, adaptability, and intensity of reactions.
Classic examples come from models like:
- Thomas and Chess's nine dimensions (e.g., easy, difficult, slow-to-warm-up temperaments).
- Rothbart's model emphasizing reactivity (positive/negative affect) and effortful control.
In essence, temperament is the **raw emotional and behavioral wiring** you're born with.
### Personality
Personality is a broader, more comprehensive construct that describes the **enduring patterns of thoughts, feelings, and behaviors** that characterize an individual and distinguish them from others. It emerges over time and is shaped by both innate factors and environmental influences.
Key characteristics:
- Develops gradually through childhood, adolescence, and adulthood.
- Influenced by temperament **plus** life experiences, culture, socialization, learning, and environment.
- More flexible and malleable than temperament (though core traits remain fairly stable in adulthood).
- Encompasses not just emotional reactivity but also cognitive styles, values, motives, attitudes, and social behaviors.
Common frameworks include:
- The Big Five (OCEAN): Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism.
- Other models like Myers-Briggs or trait theories.
Personality is the **full, integrated pattern** of who a person is, including how they think, relate to others, and pursue goals.
### Main Differences
| Aspect | Temperament | Personality |
|---|---|---|
| Origin | Primarily biological/genetic | Biological + environmental/experiential |
| Onset | From birth/infancy | Develops over time (fully matures in adulthood) |
| Stability | Highly stable across life | Relatively stable but more changeable |
| Scope | Narrow: basic emotional/behavioral style | Broad: includes cognition, values, social patterns |
| Changeability | Difficult to change (core wiring) | Can evolve with experiences, therapy, etc. |
| Relationship | Forms the core foundation of personality | Builds upon temperament + learned elements |
### How They Relate
Temperament is often seen as the **biological substrate** or "building block" of personality. For example:
- A highly reactive temperament (e.g., intense negative emotions) may predispose someone to higher Neuroticism in the Big Five personality model.
- However, environment can moderate this: supportive parenting might help a difficult-tempered child develop better self-regulation, leading to a more adaptive personality.
In short, temperament is the **inborn emotional tone**, while personality is the **full symphony** that develops from that tone plus life's experiences. Psychologists generally agree that temperament contributes significantly to personality but does not fully determine it.
