Personality Psychology: Understanding Individual Differences

Study Notes

Personality psychology is a branch of psychology that focuses on the study of personality and individual differences.
It aims to understand individual characteristics, such as thoughts, feelings, and behaviors, that shape a person's unique personality.

Trait Theory: proposes that personality is composed of stable, enduring patterns of behavior, thought, and emotion.
- Examples: Big Five personality traits (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism)
Psychodynamic Theory: suggests that personality is shaped by unconscious thoughts, feelings, and experiences from early childhood.
- Developed by Sigmund Freud
Humanistic Theory: emphasizes the role of personal growth, self-actualization, and subjective experience in shaping personality.
- Developed by Carl Rogers
Biological Theory: proposes that personality is influenced by genetic and neurobiological factors.
- Examples: genetics, neurotransmitters, brain structure

Self-report measures: ask individuals to rate their own personality traits or behaviors.
- Examples: personality questionnaires, surveys
Observer-report measures: ask others to rate an individual's personality traits or behaviors.
- Examples: peer ratings, parental ratings
Behavioral measures: observe and record an individual's behavior in controlled or naturalistic settings.
- Examples: laboratory tasks, observational studies

Nature vs. Nurture debate: the relative influence of genetic (nature) and environmental (nurture) factors on personality development.
Stability and change: personality traits can be relatively stable across adulthood, but can also change in response to life experiences.

Clinical psychology: understanding personality can inform the diagnosis and treatment of mental health disorders.
Industrial-organizational psychology: applying personality psychology to improve workplace performance and selection.
Education: understanding personality can inform teaching strategies and student learning outcomes.
