Psychology Concepts Quiz

What does evolutionary psychology focus on?

• How families influence children’s learning

• How society teaches moral values

• How natural selection has shaped human behavior and traits

• How memories are stored in the brain

What is natural selection?

• Traits that help survival and reproduction get passed on

• Random changes in DNA across generations

• Traits passed down only from the mother’s side

• Traits that people choose to adopt

What does behavior genetics study?

• How organisms evolve across generations

• How society changes over time

• How brain chemicals affect learning

• How environment and genes influence behavior

What does “environment” mean in psychology?

• The genetic code inside an individual

• Family rules and expectations only

• Only the natural world, like forests and rivers

• Every external influence, such as prenatal nutrition and culture

What are genes?

• Traits caused only by the environment

• Units of heredity made of DNA that make up chromosomes

• Complete DNA instructions for making an organism

• Structures that process information in neurons

What is a genome?

• The ability of genes to mutate

• The full set of genetic instructions for an organism

• A single chromosome segment

• Random collection of traits from parents

What are identical (monozygotic) twins?

• Twins that share 50% of their genes

• Twins raised in the same environment but not biologically related

• Twins developed from one fertilized egg that splits, genetically identical

• Twins that come from separate eggs, like siblings

What are fraternal (dizygotic) twins?

• Twins who share the same personality

• Twins raised in different environments

• Twins from separate eggs, no more alike than siblings

• Twins from the same egg, genetically identical

What do twin studies compare?

• Random children from different countries

• Adopted children with their adoptive parents

• Siblings and cousins raised together

• Identical and fraternal twins to study heredity vs. environment

What do adoption studies compare?

• Identical twins raised apart

• Parents with grandparents

• Genes with epigenetic changes

• Adopted children with biological and adoptive parents
