Personality Psychology Notes

  • Explores why people are the way they are.

  • Asks why individuals are the way they are.

  • Considers people in their entirety as individuals and complex beings.

  • Seeks to find order and meaningful connections out of complexity.

What Does Personality Mean?

  • Everyday Meaning (Laypeople):

    • Describes specific characteristics (e.g., outgoing, shy).

    • Describes specific people (e.g., friend, flatmate).

  • Psychologists’ Meaning:

    • Abstract construct.

    • Applies to all people.

    • Definable, measurable, applicable.

    • Consistent across situations.

Why Do We Conceptualize Personality?

  1. Conveys a sense of consistency or continuity over time, place, and person.

  2. Suggests internal origins of thoughts, feelings, and behaviors.

  3. Helps predict and understand behavior.

  4. Captures a sense of personal distinctiveness – a person’s prominent characteristics.

Sources of Influence on Personality

  • Personality is influenced by the situation, thoughts, and feelings, these all combine to influence behaviour.

Definition of Personality

  • Personality is a dynamic and organized set of characteristics possessed by a person that uniquely influences their cognitions, motivations, and behaviors in various situations (Ryckman, 2004).

Key Features of the Definition

  • Personality:

    • Has an organized structure.

    • Involves active processes.

    • Has psychological and physiological components.

    • Helps determine how people relate to the world.

    • Demonstrates patterns and consistencies.

    • Manifests itself across a range of thoughts, feelings, and behaviors.

Two Fundamental Themes

  1. Individual Differences:

    • Represent differences between people.

    • Examples: level of aggression, sociability, optimism.

  2. Intrapersonal Functioning:

    • Stable processes that underlie thoughts, feelings, behaviors.

    • Examples: goals or motives.

    • Create continuity and consistency within the person, even if they act differently in different circumstances.

  • Uniqueness vs. process.

Why Do We Need Theories of Personality? What Is Their Purpose?

  • Theories provide a general principle or set of principles about a class of events.

  • Theories of personality are a systematic effort to discover and explain regularities in thought, feeling, and behavior.

    • To explain what we know – e.g., why do children often act or react similarly to their parents? (social learning theory).

    • To predict possibilities that have not been examined – e.g., similar personalities between biological parents and their children (biological theories).

Theory and Research: Interconnected

  • Theory makes predictions.

  • Research tests theory:

    • Verifies.

    • Suggests changes.

What Makes a Theory Good?

  1. Explains what is known – organizes existing data.

  2. Predicts what will happen – testable, points to the discovery of what is not currently known.

  3. Comprehensive - encompasses and accounts for a wide variety of data.

    • How many different kinds of phenomena can be explained?

    • Are these central and important to understanding human behavior?

  4. Parsimonious – simple and internally consistent.

  5. Research relevance – useful or not; leads to hypotheses that can be tested.

  6. Personal and intuitive appeal.

  7. Interesting.

  8. Provocative.

    • Subjective – needs to be appealing, or no one bothers to study them!

Metatheory

  • Focus and examples:

    • Dispositional: Stable qualities in people.

    • Biological: Biological processes as influence of behavior.

    • Psychoanalytic: Competition and conflict among internal psychic forces.

    • Neoanalytic: ‘Ego’ development and social relationships.

    • Learning: Systematic behavior change resulting from experience.

    • Phenomenological: Subjective experience and tendency toward self-actualization.

    • Cognitive self-regulation: Patterns in behavior arising from cognitive processes.

Central Aspects of a Personality Theory

  1. Structure – basic units of personality.

  2. Process – dynamic aspects.

  3. Development and growth – develop into unique individuals.

  4. Psychopathology – adaptive or non-adaptive functioning.

  5. Change – how and why we change (or not).

1. Structure

  • Stable and enduring aspects of personality.

  • Traits – consistency of an individual’s response across situations, e.g., conscientiousness, introversion.

  • Type – the clustering of many traits, e.g., adaptive and resilient; inhibited; uninhibited.

  • Personality theories differ according to the types of structural units/concepts:

    • Complex systems with many components linked in various ways.

    • Simple systems with a few components.

    • Some theories are structured hierarchically.

    • Some units are higher order and control the function of other units.

2. Process

  • Theories can be compared with respect to the dynamic, motivational concepts used to account for behavior.

  • Pervin (1996) maintains there are three major categories of motivational concepts used by personality psychologists:

    1. Pleasure or hedonic.

    2. Growth or self-actualization.

    3. Cognitive motives.

3. Development and Growth

  • A profound challenge for personality psychologists: accounting for individual differences.

  • Nature-nurture – personality is determined by:

    • Genetic determinants.

    • Environmental determinants.

3. Development and Growth: Genetic Factors

  • More important for intelligence and temperament.

  • Less important for values and beliefs.

  • Evolutionary heritage.

  • Patterns of behavior shared with other species.

  • Genes influence our similarities and differences.

3. Development and Growth: Environmental Factors

  • Cultures.

  • Social groups.

  • Families.

  • Peer groups.

  • Time and place.

Genetic vs. Environmental Determinants?

  • Personality development is the result of ongoing interactions between genes and environments.

  • Gottesman (1963) – heredity fixes a number of possible outcomes, but the environment determines which.

  • Reaction range – genes define limits, e.g., talent for music or sport.

  • However, there is an active ongoing relationship between nature and nurture, e.g., a child with easy vs. difficult temperament.

4. Psychopathology

  • Theories should explain why some people cope with stress and challenges (adaptive) and others experience more difficulties (maladaptive).

  • Personality disorders - covered in PSYC601 next semester.

5. Change

  • How and why do people change, or resist change?

  • How can maladaptive behavior (and emotional and thought patterns) be changed? (Psychological interventions, therapy).

Individual Theories of Personality

  • Attempt to describe human nature.

  • Have different orienting assumptions.

  • May be grouped by metatheoretical perspectives.

  • May have overlapping connections.

  • May be (intentionally) limited in scope.
