⩥ What is heritability and what information does heritability gives us?
Answer: - Heritability is the percentage of variance that is genetic ranges
from 0 to 1, the percentage of differences between people that can be
explained by genetic differences
-
⩥ How do you calculate heritability? Answer: (h) = 2 x (rMZ-rDZ)
⩥ What are the major research designs that are used to assess
heritability? What are the strengths? Answer: - Twin studies, have a
common shared environment, but identical twins may be treated
differently than fraternal twins which violates shares environment
assumptions
- Adoption studies, does not equal biological gender, children are nor
randomly assigned to families, and adoptive parents are different than
general population
⩥ What is a gene-environment interaction and how do these interactions
affect behavior/personality? Answer: -A gene-environment interaction
(G×E) happens when the effect of your genes depends on the
,environment you're in, OR the effect of your environment depends on
your genes.
-Can explain why people respond differently to the same environment,
they show why genes are not destiny
⩥ Evocative person-environment Answer: A child's genetically
influenced traits evoke certain responses from the environment
⩥ Active person-environment Answer: People seek out environments
that match their genetic tendencies.
⩥ Reactive person-environment interaction Answer: The child's
genetically influenced traits evoke reactions from others.
⩥ What is the equal environment assumption? Answer: Identical (MZ)
and fraternal (DZ) twins experience equally similar environments.So any
extra similarity between MZ twins must be due to genetics, not the
environment.
⩥ Epigenetics Answer: The study of how the environment can change
the way genes are expressed without changing the DNA sequence itself.
⩥ Can heritability be individualized? Answer: Heritability estimates are
strongly determined by particular group being studied, so heritability
, estimates apply to groups, not individuals, estimates also vary according
to assessment method
⩥ How are genes showed through behavior? Answer: Genes —->
Heritable Traits (Neuroticism, Traditionalism, Impulsivity, Dominance)
—> Behavior (overeating, voting, divorce)
⩥ What was the result of the study of borderline personality disorder in
lecture? Answer: - Adolescent female twin pairs from Minnesota, ages
14 to 24, self reported measures of BPD
-As we get older, we start to choose our own environments, hobbies,
activities, friends, relationships which allows genetic tendencies to
express themselves more clearly
-Shared environment decreases, nonshared environment is the biggest
factor
-BPD deacreases as people age
-rank-order stability is high
⩥ What was the Nurture Assumption? Answer: -Challenged effects of
parenting (shared environment)
-Parenting studies don't account for genes
-Adoption studies show few parenting effects
-Stressed nonshared environment (peers, neighborhoods)
-Shared environment effects are small
