All Flashcards
Define 'Nature' in the context of psychology.
Innate qualities, including genetic predispositions, inherited from parents.
Define 'Nurture' in the context of psychology.
Environmental factors that influence development, including family, culture, and experiences.
Define 'Natural Selection'.
The process where traits that enhance survival and reproduction are passed on to future generations.
Define 'Adaptive Behaviors'.
Behaviors that increase chances of survival and reproduction in a specific environment.
Define 'Eugenics'.
A flawed and unethical idea that selective breeding can 'improve' the human race.
Define 'Heritability'.
The proportion of variation among individuals in a group that we can attribute to genes.
Define 'Twin Studies'.
Research that compares traits and behaviors of identical and fraternal twins.
Define 'Family Studies'.
Research that examines how traits are shared among genetically related individuals.
Define 'Adoption Studies'.
Research that compares adopted children to their biological and adoptive families.
Define 'Evolutionary Psychology'.
A branch of psychology that studies the evolutionary roots of behavior and mental processes.
Give an example of how a fear can be explained through evolutionary psychology.
A fear of snakes may have evolved because it helped early humans avoid venomous bites, increasing survival.
How can twin studies be used to understand the heritability of schizophrenia?
If identical twins are more likely to both have schizophrenia than fraternal twins, it points to a genetic component to the disorder.
How can adoption studies be used to understand the heritability of intelligence?
If adopted children's IQ scores are more similar to their biological parents' scores, it suggests a genetic component to intelligence.
How might altruism be explained from an evolutionary perspective?
Altruism may have evolved because helping others in a group could increase the group's survival and thus the individual's genes being passed on.
How does the concept of nature vs. nurture apply to the development of musical talent?
A child might have a genetic predisposition for musical talent (nature), but without exposure to instruments and lessons (nurture), that potential may go unrealized.
How can understanding evolutionary psychology help us understand mate selection?
Mate selection preferences may have evolved to maximize reproductive success, such as preferring partners with traits indicating health and fertility.
How can evolutionary psychology explain aggression?
Aggression may have evolved as a way to compete for resources, protect territory, or defend oneself and offspring.
How can family studies help understand the genetic basis of depression?
If depression runs in families more than would be expected by chance, it may have a genetic basis.
How can eugenics be applied in real life?
Eugenics has been used to discriminate against marginalized groups and justify atrocities like forced sterilization.
How can the understanding of nature vs. nurture be applied to education?
Understanding that both genes and environment play a role in learning can help educators tailor instruction to individual needs and provide enriching experiences.
What is the effect of shared genes in identical twins on psychological traits?
Identical twins often exhibit more similar psychological traits compared to fraternal twins, suggesting a genetic influence.
What is the effect of environmental factors on genetically predisposed behaviors?
Environmental factors can either enhance or suppress the expression of genetically predisposed behaviors.
What is the effect of natural selection on human behavior?
Natural selection has shaped human behavior by favoring traits that enhance survival and reproduction.
What is the effect of adopting a child on their development?
Adoption provides a different environment which can influence the child's development, potentially leading to different outcomes compared to their biological family.
What is the effect of eugenics on society?
Eugenics has been used to discriminate against marginalized groups and justify atrocities like forced sterilization.
What is the effect of a genetic predisposition for a mental disorder?
A genetic predisposition increases the likelihood of developing the disorder, but environmental factors also play a crucial role in whether it manifests.
What is the effect of early childhood experiences on brain development?
Early childhood experiences can significantly shape brain development, influencing cognitive and emotional functioning.
What is the effect of cultural norms on behavior?
Cultural norms can influence behavior by providing guidelines and expectations for how individuals should act in different situations.
What is the effect of social isolation on mental health?
Social isolation can have negative effects on mental health, leading to increased risk of depression, anxiety, and other psychological problems.
What is the effect of chronic stress on physical and mental health?
Chronic stress can have detrimental effects on physical and mental health, increasing the risk of various diseases and psychological disorders.
