Study Notes
Evolutionary Theories on Personality
- Darwin's theories of natural selection and sexual selection are the foundation for modern evolutionary psychology
- Two major types of struggles identified by Darwin:
- Struggle for existence: Competition for survival in a world with limited resources
- Struggle for mates: Competition for reproductive success through mate choice and same-sex competition
- Evolutionary psychology expanded on Darwin's ideas:
- Identifying new struggles such as within-family conflicts and conflicts between the sexes
Struggle for Existence
- Species produce more individuals than can survive leading to competition
- Organisms must adapt to environmental pressures like food scarcity, harsh weather and natural disasters
- Evolutionary psychologists have discovered adaptations in humans that help them survive:
- For example, women have better spatial memory for food locations linked to ancestral foraging
Struggle with Other Species
- Humans compete with predators and parasites; many common fears are evolutionary adaptations
- Some plants developed chemical defenses; children's aversion to certain vegetables is explained by this
Struggle with Other Humans
- Human-on-human competition exists, particularly in tribal societies, where successful warriors tend to have more wives and children
- DNA evidence shows historical conquerors' influence on modern populations
- Human psychology has adaptations for both aggression and self-defense, shaped by conflicts
Struggle for Mates
- Darwin considered traits like the peacock's tail that seem to hinder survival, but explained that it attracts mates
- Male competition (intrasexual selection):
- Men compete physically and in social status, finances and dominance displays
- They take higher risk when competing for mates (e.g., reckless behaviors)
- Female mate choice (intersexual selection):
- Women prefer men with resources, status, ambition and protection abilities
- Female preferences change based on ovulation cycles
- Women seek faithfulness and emotional commitment
Struggles Not Considered by Darwin
- Within-family conflicts
- Parent-offspring conflict: Children try to extract more resources from parents than parents are willing to give.
- Sibling rivalry: Siblings compete for parental attention and resources
- Stepchildren face higher rates of abuse and neglect
- Battle of the sexes (sexual conflict):
- Men deceive women by feigning long-term commitment to secure short-term sex
- Women deceive men by falsely signalling sexual interest to extract resources
- Coercion as well as sexual deception may evolve as sources of conflict
Evolutionary Psychology: Fulfilling Darwin's Vision
- Evolutionary psychology is realizing Darwin's prediction that psychology will be based on evolutionary foundations
- The field has revolutionized understanding of human mating, social conflicts, and cognitive adaptations
- It explains sex differences in behaviors related to reproduction
- Darwin's theories are expanded by modern research into kin selection, game theory and life history strategies
Future Directions
- Evolutionary psychology highlighted aggression, competition, and deception
- Less focus on cooperation and altruism
- Future research should investigate friendship, alliances and prosocial behaviors
Testing Predictions From Personality Neuroscience
- This research explores how brain structure correlates with personality traits
- MRI scans are used to test a biological theory of the Big Five personality traits
- Extraversion, Neuroticism, Agreeableness, Conscientiousness, Openness/Intellect
- Key findings:
- Extraversion linked to medial orbitofrontal cortex, a region for reward processing
- Neuroticism associated with dorsomedial prefrontal cortex & hippocampus, linked to self-evaluation & emotional regulation
- Agreeableness linked to superior temporal sulcus and posterior cingulate cortex, regions involved in understanding others' emotions and intentions
- Conscientiousness correlated with lateral prefrontal cortex, a region responsible for planning and impulse control
- Openness/Intellect has no strong associations with specific brain regions but some connection to parietal cortex, relevant to working memory and attention control
Voxel-Based Morphometry (VBM)
- A neuroimaging technique measuring gray matter volume in different brain regions
Medial Orbitofrontal Cortex
- Involved in reward processing, linked to Extraversion
Dorsomedial Prefrontal Cortex (dmPFC)
- A region involved in self-evaluation and emotional regulation, linked to Neuroticism
Superior Temporal Sulcus
- A brain area linked to social cognition and understanding others' intentions, associated with Agreeableness
Lateral Prefrontal Cortex
- Involved in planning, impulse control, and goal-directed behaviour, and related to Conscientiousness
Openness/Intellect
- One of the Big Five traits, linked to abstract thinking, creativity, and curiosity
