Selective Breeding
Family Studies
Twin Studies
Dream Analysis
Advocates of the eugenics movement believed…
Genes and environment are equally important
Human traits could be improved by selective reproduction
Adoption was the best way to study heritability
Twin studies were unreliable
Monozygotic twins share what percentage of their genes?
25%
50%
75%
100%
Which is a limitation of adoption studies?
Adoptive families are not representative of the population
Identical twins cannot be separated at birth
Children rarely share environments with their parents
Genes cannot be measured directly
The DRD4 (D4DR) gene is associated with which trait?
Aggression
Sensation seeking/novelty seeking
Anxiety
Memory
Electrodermal activity (EDA) measures…
Heart rate
Skin conductance/sweat
Brain waves
Blood sugar levels
Eysenck’s revised theory of extraversion states…
Extraverts have lower resting arousal
Introverts are more reactive to stimulation
Extraverts are more sensitive to punishment
Introverts seek less stimulation because they are under-aroused
The Behavioral Inhibition System (BIS) is most responsive to…
Rewards
Punishments
Novelty
Memory
According to Hebb’s optimal arousal theory, people…
Avoid stimulation at all costs
Always seek maximum stimulation
Prefer low levels of arousal
Seek a balance of stimulation
Which of the following is an example of an adaptation?
A belly button
Fear response to predators
Hairline shape
Junk food cravings
Intersexual selection occurs when…
Members of one sex compete with each other for mates
Traits evolve because they aid survival
Mates are chosen based on preferences
Children inherit random mutations
According to jealousy research, which statement is correct?
Men are more distressed by emotional infidelity
Women are more distressed by sexual infidelity
Men are more distressed by sexual infidelity, women by emotional
Both men and women are equally distressed by both types
Hamilton’s Inclusive Fitness Theory says…
Helping family members increases the survival of shared genes
People always act selfishly to maximize their own reproduction
Genes only matter when expressed in personality traits
Aggression ensures reproductive success
A child is naturally shy. Teachers give the child fewer opportunities to present in class, and peers stop inviting them to group activities, reinforcing the shyness.
Passive genotype-environment correlation
Reactive genotype-environment correlation
Active genotype-environment correlation
Shared environment
Sarah and her identical twin sister were adopted by different families at birth. Researchers compare their personalities later in life. This design best illustrates…
The eugenics movement
Family study limitation
Ideal behavioral genetics study
Non-shared environment study
John’s parents both smoke, and he inherits genes that make nicotine especially rewarding. His parents also leave cigarettes around the house. John begins smoking at an early age.
Passive correlation
Active correlation
Genotype-environment interaction
Shared environment
During a stressful math test, a student’s blood pressure and heart rate increase sharply. This is an example of…
Electrodermal activity
Cardiac reactivity
BAS activation
Optimal arousal
Two people both have the same resting arousal levels. But one feels overwhelmed and distracted in noisy environments, while the other thrives in them. This supports…
Eysenck’s original theory of extraversion
Eysenck’s revised theory of extraversion
Hebb’s theory of optimal arousal
Sensory deprivation studies
Maria takes big risks because she gets highly motivated by the possibility of winning rewards, but punishment doesn’t affect her much. This reflects…
BIS dominance
BAS dominance
High neuroticism
Low sensation seeking
A participant is placed in a soundproof room with no visual input. After a few hours, they report strong discomfort and even hallucinations. This study demonstrates…
BIS vs BAS differences
Shared vs non-shared environment
Human need for sensory input
Optimal arousal
A man gets into a physical fight with another man over access to a potential mate. This illustrates…
Intersexual competition
Intrasexual competition
Natural selection
Proximate explanation
Women (on average) report being more distressed by their partner forming an emotional bond with another woman than by a one-night stand. This finding supports…
Inclusive fitness theory
Evolutionary perspective on jealousy
Discord in modern society
Proximate explanation
People today crave sugary, fatty foods because these cravings helped our ancestors survive in food-scarce environments. In the modern world, this mismatch is called…
Adaptation
Byproduct
Random variation
Discord
A belly button is an example of…
Adaptation
Byproduct of adaptation
Random variation
Ultimate explanation
Why are men (on average) more likely to engage in aggressive behavior than women, according to evolutionary theory?
Men have higher BIS activity
Men are more likely to inherit the aggression gene
Historically, aggression increased reproductive success
Men have lower optimal arousal thresholds
