Notes on Personality and The Self

Learning Objectives

  • Compare and contrast the psychodynamic, humanistic, trait or Big Five, and social–cognitive theories of personality.
  • Debate the validity of self-report inventories versus projective tests as measures of personality.
  • Differentiate distinct aspects of self (self-concept, self-awareness, self-esteem, self-regulation) in terms of content, sources, and implications.
  • Analyze evidence for biological bases of personality and self.
  • Distinguish between personal and interpersonal self and relate them to cultural differences in individualistic vs. collectivistic self-concepts.

Personality as Adaptation

  • Different traits and personalities can be better suited for different environments, similar to how specific traits like a moth's color can enhance adaptation.
  • Examine the role of culture in shaping personality traits, and conversely, how groups of personalities can affect their cultural environment.
Genetics and Personality
  • The serotonin transporter gene (5-HTTLPR) has two variants, short (S) and long (L).
  • Individuals with the SS genotype react more negatively to bullying compared to other genotypes.
  • Distribution of alleles varies globally, indicating potential cultural and evolutionary influences.
  • Cultural tightness (strict social norms) relates to genetics; individuals with the S allele may help develop tight cultures through enhanced threat perception.

Cultural Influences on Personality

  • Cultural configurations vary between tight (strict social norms) and loose cultures (more tolerance for deviance).
  • Tight cultures tend to emerge in response to ecological threats; loose cultures adapt when threats are minimal.

Major Theories of Personality

Psychodynamic Theory (Freud)
  • Personality comprises id (primitive urges), ego (practical self), and superego (morality).
  • Defense mechanisms are used by the ego to protect against anxiety, e.g., sublimation redirects negative energy into socially acceptable actions.
  • Five psychosexual stages of development influence personality formation, through conflicts between id and reality.
Humanistic Approaches
  • Focus on intrinsic goodness and the individual's potential for growth.
  • Maslow: Developed the concept of self-actualization, identifying traits of exceptional individuals.
  • Rogers: Proposed genuineness and unconditional positive regard as vital for development towards a healthy self.
Trait Theories
  • Personality traits represent stable characteristics; the Big Five: Openness, Conscientiousness, Extroversion, Agreeableness, and Neuroticism (OCEAN).
  • Early approaches involved identifying traits through lists and refining them using statistical methods like factor analysis.
The Big Five Theory
  • Openness: Creativity; curious individuals seek new experiences.
  • Conscientiousness: Reliability; organized behavior leads to stability in tasks and responsibilities.
  • Extraversion: Sociability; extroverts are often energetic and assertive.
  • Agreeableness: Compassionate and cooperative towards others; low levels can indicate being disagreeable.
  • Neuroticism: Emotional stability vs. instability; high neuroticism correlates with anxiety and stress.

Social-Cognitive Theories

  • Emphasize the interplay between individual traits and situational factors.
  • Locus of Control: Differentiates between internal (own actions impact outcomes) and external factors (luck influences outcomes).
  • Reciprocal Determinism (Bandura): The mutual influence of the person and their environment on behavior and personality development.

Biological Bases of Personality

  • Biological theories examine genetics, temperament, and brain structure, linking them to personality traits.
  • Studies show a heritability factor of around 0.50 for the Big Five traits; genetics interact with environments to shape personality.

Assessing Personality

  • Personality assessments vary, including observation, interviews, and standardized tests (e.g., MMPI, Big Five Inventory).
  • Self-report inventories may lack the ability to capture implicit aspects of personality, potentially skewed by social desirability bias.
  • Advances in technology, including social media analysis, offer new methods for more accurate personality assessments.
Conclusion
  • An understanding of personality requires integrating multiple theoretical perspectives along with cultural and biological insights.
  • Continuous research into both genetic predispositions and environmental influences impacts the understanding and assessment of personality.
