    Study Notes

    Lexical Methodologies

    • Terms used to distinguish people based on their behavior
    • Terms that describe common behaviors (e.g., walking, digesting) are excluded
    • Four categories of terms:
      • Censorial and evaluative (e.g., insignificant, acceptable, worthy)
      • Metaphorical (e.g., red-headed, lean)

    Problem of Lexical Accounts

    • Lexical accounts of personality describe traits, but don't explain them
    • Questions to be answered:
      • Why do we behave in and experience the world as we do?
      • What is the source of individual differences in behavior and experience?

    Psychobiological Methodologies

    • Hans Eysenck: 'Father' of modern biological approaches to personality
    • Assumptions:
      • Personality develops through the interplay between:
        • Cognition (memory, perception, thought, language, intelligence)
        • Temperament (characteristic, biologically-based reaction patterns)
        • Constitution or physiology (neurology, endocrinology, genetics, etc.)
        • Environment (both human and physical)
      • Personality is dimensionally and hierarchically arranged

    Two Main Trait Taxonomies

    • Lexical taxonomy (e.g., Big-5):
      • Seeks to identify personality trait-descriptors in natural language
      • Five dimensions:
        • Neuroticism: emotional stability
        • Extraversion: social/interpersonal impact
        • Agreeableness: quality of social/interpersonal impact
        • Conscientiousness: responsibility, dutifulness, and will to achieve
        • Openness: artistic tendencies, intellect, and acceptance of new ideas or change
    • Psychobiological taxonomy (Eysenck's Big-3):
      • Seeks to identify biological/genetic markers of personality traits
      • Three dimensions:
        • Neuroticism (related temperament: emotionality): predisposition to mood and anxiety disorders
        • Extraversion (related temperament: activity): predisposition to accidents, injuries, and substance abuse
        • Psychoticism (tough- vs. avoidance)

    Assumptions of the Trait Approach

    • Common assumptions:
      • The personality space is made up of dimensions
      • These dimensions are finite
      • We can discover these dimensions by categorizing lexical evidence and biological data
      • These dimensions are linear and independent from each other

    Dimensionality: Linearity and Independence

    • Dimensionality: linearity is assumed, but in reality, dimensions are likely oblique and non-linear
    • Independence: examined whether extraversion (E) and neuroticism (N) are independent except amongst high N scorers

    Contributions of the Trait Approach

    • Scientific theories that are evidence-based
    • Clear-cut and reliable predictions
    • Testable and probabilistic
    • Cross-cultural (also gender/age) validity
    • Direct applications to occupational/educational psychology, psychopathology, and evolutionary psychology
    • Contributions to criminal profiling and adaptive interrogation techniques

    Limitations of the Trait Approach

    • Can't manage complex, dynamic interactions between elements of personality
    • Statistical methods of analysis assume linearity and independence
    • Lexical approach can't identify what personality traits are
    • Biological approach is generally unreliable
    • How to account for changes in personality traits through adulthood?
    • Theoretically weak
