    Study Notes

    Heritability and Personality

    • Heritability is the percentage of variance in a trait due to genetics.
    • It helps understand how much personality differences are genetic vs environmental.
    • It provides insights into the biological basis of personality, linking it to other traits.

    Genetic and Environmental Influences

    • Genetic influences: Inherited predispositions towards traits like extroversion, etc.
    • Environmental influences:
      • Upbringing, social interactions, and life experiences.
      • Shared Environments: Aspects common to siblings within a family.
      • Non-shared Environments: Unique experiences that differentiate siblings.
        • Plays a larger role in shaping personality differences between siblings.

    Gene-Environment Correlations

    • Passive: Children inherit both genes and environment from parents.
    • Reactive (Evocative): Genetic traits influence how others interact with them.
    • Active: Individuals actively choose environments based on genetic predispositions.

    Dangers of Studying Behavioral Genetics

    • Genetic Essentialism: Genes solely determine behavior.
    • Discrimination: Based on genetic predispositions.
    • Privacy Concerns: Regarding genetic data.
    • Social Stigma: Attached to certain genetic variations.
    • Misuse of Research: For eugenics.
    • Overlooking Environmental Factors: Which significantly influence behavior.

    Gender and Sex Differences in Personality

    • Women are more sensitive to relevant information provided in decision-making contexts.
    • Factors influencing gender differences:
      • Cultural Background.
      • Gender-specific roles.
      • Evolutionary Account: Gender differences arose from different adaptive challenges faced by men and women.

    Gender Differences Across the Lifespan

    • Gender differences tend to become more pronounced with age.
    • Early Life: The largest gap in life expectancy usually starts during adolescence.
    • Midlife: Women generally have better health outcomes and lower mortality rates.
    • Later Life: Women are more likely to experience chronic diseases, men heart diseases and cancer.
    • Factors contributing to gender differences:
      • Biology: Hormones, genetics, immune system functions.
      • Lifestyle behaviors: Men tend to engage in risky behaviors.
      • Social Expectations: Influence health-seeking behaviors and healthcare access.
      • Healthcare Access: Women often have better access to preventive healthcare.

    Physiology of Personality

    • Neurotransmitters regulate mood, motivation, and behavioral responses to stimuli.
    • Dopamine: Linked to novelty-seeking and reward-driven behavior.
      • High levels: More extroversion, sociability, and openness.
      • Low levels: Decreased motivation, lethargy, and potential for depression.
    • Serotonin: Associated with mood stability and harm avoidance.
    • Norepinephrine: Related to alertness and arousal.
      • May impact traits like extroversion, neuroticism, and conscientiousness.

    MAO and its Relevance to Behavior

    • Monoamine Oxidase (MAO) is an enzyme that breaks down neurotransmitters like dopamine, norepinephrine, and serotonin.
    • Low MAO activity: Linked to higher levels of these neurotransmitters, possibly associated with traits like sensation-seeking, impulsivity, and aggression.
    • High MAO activity: May be related to more cautious, introverted personalities.

    Culture and Personality

    • Cultures: Shape values, beliefs, and behaviors individuals learn through socialization.
      • Transmitted Culture: Learned practices passed down through generations.
      • Evoked Culture: Behaviors triggered by environmental factors across cultures.
    • Moral Judgments: Differ across cultures due to varying social norms, values, religious beliefs, and historical contexts.
    • Moral Foundations Theory:
      • Five key foundations:
        • Care/Harm, Fairness/Reciprocity, Loyalty/Betrayal, Authority/Respect, and Purity/Sanctity.
      • Weighted differently depending on the culture.

    Eastern vs Western Cultures

    • Western Cultures: Tend to be more individualistic.
    • Eastern Cultures: Tend to be more collectivist.
    • Social orientation affects reasoning and other fundamental aspects of behavior.
