Psychology: Understanding Temperament

Study Notes

Temperament refers to the unique personality traits and characteristics that influence an individual's behavior, emotions, and interactions with others.
It is a relatively stable and enduring aspect of an individual's personality, present from early childhood.
Temperament is often seen as a biological or genetic component of personality, shaped by an individual's genetic makeup and early life experiences.

Thomas and Chess's Theory: Proposes three main temperamental categories:
- Easy temperament: adaptable, calm, and regular
- Difficult temperament: sensitive, moody, and irregular
- Slow-to-warm-up temperament: cautious, slow to adapt, and reserved
Kagan's Theory: Focuses on the role of emotional reactivity and regulation in temperament, proposing two main categories:
- Inhibited temperament: shy, anxious, and cautious
- Uninhibited temperament: outgoing, bold, and impulsive

Emotional Reactivity: The ability to regulate and manage emotions, including emotional intensity, sensitivity, and reactivity.
Activity Level: The level of energy, enthusiasm, and movement an individual exhibits in their daily activities.
Sociability: The tendency to seek out and engage in social interactions, including the desire for social contact and responsiveness to others.
Regulatory Capacity: The ability to regulate and control one's behavior, including self-control, impulsivity, and persistence.

Genetics: Temperament is influenced by genetic factors, with heritability estimates ranging from 20% to 60%.
Environment: Early life experiences, parenting styles, and cultural influences can shape an individual's temperament.
Brain Structure and Function: Research suggests that temperament is linked to specific brain regions and systems, including the amygdala, prefrontal cortex, and dopamine system.

Developmental Outcomes: Temperament can influence developmental outcomes, such as social skills, emotional well-being, and academic achievement.
Mental Health: Temperament can contribute to the risk of mental health disorders, such as anxiety and depression.
Interpersonal Relationships: Temperament can affect interpersonal relationships, including romantic relationships, friendships, and family dynamics.
