Questions and Answers

Why did many psychologists resist the notion of biology playing a role in human personality?

  • Biology was not considered a relevant factor in shaping human personality until recent years.
  • Psychologists did not have enough knowledge and resources to understand the biological aspect of personality.
  • The 'blank slate' view of humankind was appealing, allowing for the molding of an individual's personality through experiences. (correct)
  • Personality traits such as low self-esteem, pessimism, and neuroticism were difficult to eliminate through biological factors.

    • What was one reason for psychologists' reluctance to accept the role of biology in shaping human personality?

  • Insufficient research on the biological aspects of personality
  • The lack of understanding about genetic heritability
  • The belief that personality could be formed exclusively by experiences (correct)
  • The difficulty in quantifying the impact of biology on personality traits

    • What was the appeal of the 'blank slate' view of humankind?

  • The understanding of genetic heritability in forming personality traits
  • The recognition of biological influence on extraversion-introversion traits
  • The acknowledgment of evolutionary personality theory in mate selection
  • The potential to mold an individual's personality through experiences (correct)

    Study Notes

    • Genetics play a role in the formation of adult personalities, as shown by studies comparing the personalities of adopted children with those of their biological mothers and adoptive parents.

    • The children resemble their biological mothers more than their adoptive parents in terms of personality scores.

    • However, the relationship between genetics and personality formation is weaker than suggested by twin-study data.

    • Twin studies using methods such as separating twins at birth and raising them in different households provide additional evidence for genetic influence on personality.

    • Identical twins, even when raised apart, tend to be similar in personality.

    • Researchers making assumptions in twin-study research include the accurate identification of MZ and DZ twins and the assumption of equal environments for both types of twins.

    • Adoptions are not random events and may introduce similar environmental influences on personality for twins.

    • Parents may treat identical twins as one unit and emphasize their differences, potentially skewing the environmental comparison between MZ and DZ twins.

    • Other procedures used to study the influence of genetics on personality also rely on questionable assumptions.

    • Extraversion-Introversion (E-I) is a prominent personality dimension, often easily identified after a short interaction with someone.

    • Extraversion is the most heritability-studied personality trait.

    • Twin studies suggest a higher genetic influence on personality than other methods due to nonadditive gene effects.

    • MZ twins share identical genes and identical combinations of genes influencing personality, while DZ twins may not.

    • Nonadditive gene effects show up in identical twins but not fraternal twins.

    • Extraversion-Introversion is linked to heritability research, specifically in relation to Hans Eysenck's theory of preference for arousal.

    • Online researchers have found that extraversion is the most accurately perceived personality dimension.

    • Eysenck's theory of preference for arousal suggests introverts require less stimulation to reach optimal arousal levels than extraverts.

    • A question addressed in the text is whether introverts or extraverts are happier.

    • Eysenck advocated that genetics plays a significant role in determining whether someone is introverted or extraverted.

    • Introverts and extraverts may receive advice to act differently from others based on their personality type.

    • The text implies that a person's E-I status can't be easily changed, and parents might have different expectations for adopted children.

    • Researchers are using new methodological and technological developments to uncover connections between DNA markers and personality traits.

    • Despite ongoing research, the influence of genetics on adult personalities is still an open question.

    • Extraverts generally experience more happiness than introverts (Srivastava, Angelo, & Vallereux, 2008; Diener, 1984).

    • Extraverts tend to have more social contacts and interact with them more frequently (Srivastava, Angelo, & Vallereux, 2008).

    • Social contact is closely linked to feelings of well-being, as it satisfies many basic needs such as social competence and worthiness (Smillie et al., 2015).

    • Friends serve as a buffer against stress and help extraverts cope with problems better than handling situations alone (Amirkhan et al., 1995; Zelenski et al., 2012).

    • Extraverts are more sensitive to rewards and enjoy the pursuit of rewards more than introverts (Oerlemans & Bakker, 2014; Rusting & Larsen, 1998; Smillie et al., 2012).

    • Extraverts are more likely to seek out tasks that make them happy and find rewards in situations where introverts don't see them (Tamir, 2009; Noguchi et al., 2006; Rusting, 1999).

    • Extraverts are linked to problems with alcohol and impulsivity (Fairbairn et al., 2015; Grekin et al., 2006; Hill et al., 2000; Emmons & Diener, 1986).

    • Acting impulsively can lead to problem behaviors and poor decision-making (Emmons & Diener, 1986).

    • Research indicates that the correlation between extraversion and happiness is higher in cultures where acting extraverted is consistent with the cultural norm (Fulmer et al., 2010).

    • High levels of extraversion are related to higher levels of overall psychological well-being (Kokko et al., 2013).

    • Measuring participants' extraversion at age 16 and again at age 26 predicted higher levels of well-being and life satisfaction when contacted decades later (Gale et al., 2013).

    • The higher the average extraversion score in a country, the higher the average citizens' sense of well-being (Steel & Ones, 2002).

    • Extraverts experience more positive moods and happier feelings overall compared to introverts (Larsen & Kasimatis, 1990).

    • Research on men's and women's preferences for romantic partners suggests men tend to prefer younger and physically attractive women, while women look for a partner with material resources for child-rearing.

    • However, causal relationships are difficult to test due to limitations in manipulating variables like gender and physical attractiveness.

    • Alternative explanations for these findings include differences in maturity levels between men and women and the impact of cultural norms.

    • Evolutionary personality psychologists argue for the influence of instincts, but findings from studies often contradict their predictions.

    • Instincts may not be the sole determinant of romantic partner preferences, as mutual love and affection and gender equality can also play a significant role.

    • Exceptions to the rule exist, and the analysis does not apply to all individuals or sexual orientations.
