Lesson 3 Flashcards
Nature and nurture: The debate continues
person’s biological inheritance
Nature
units of hereditary informaƟon;
genes
act as blueprints for cells to reproduce themselves and
manufacture proteins that maintain life
genes
a person’s environmental experiences
nurture
includes all surrounding physical and social conditions and influences that affect the
development of living things
environment
Interaction between nature and nurture:
3rd layer of pyramid - universal ad inherited
human nature
Interaction between nature and nurture:
2nd layer of pyramid - specific to group or category and learned
culture
Interaction between nature and nurture:
1st layer of pyramid - specific to individuan and inherited and learned
personality
the study concerned with the transmission of
traits that give rise to patterns of behavior or
the study of the relative influence of genes and environment on behavior
behavior genetics
the genetic endowment that an individual
inherits
genotype
the ways in which an individual’s genotype
is expressed in observable and measurable
characteristics
phenotype
Basic assumptions of behavior genetics
genetic effects
shared environmental effects
non-shared environmental effects
Basic assumptions of behavior genetics:
the extent to which observed phenotypic variation in a trait arises from
genetic differences among people.
genetic effects
Basic assumptions of behavior genetics:
extent to which people are similar, independent of
genetic effects, because they grew up in the same household.
shared environmental effects
Basic assumptions of behavior genetics:
the extent to which family members are different,
in spite of sharing genetic material and growing up together.
non-shared environmental effects
