Unit 1 Interaction of Heredity and Environment

Heredity —> Nature

Epigenetics, predisposed characteristics, temperament, intelligence, anger/frustration

Environmental Factors —> Nurture

Experience, Family, interactions, education, preferences, and how you change/ see how people act

Evolutionary Psychology

how natural selection effects traits, need multiple generations to conduct work

Eugenics

feeling that only the strongest survive, only smart and fit people are able to reproduce, Ex: the Holocaust

Monozygotic

same DNA and same egg, splits, can differentiate the 2 from nurture

Dizygotic

• 2 eggs were born at the same time

• family studies- look at relatives and DNA, siblings

• Adoption studies- studying effects of environment, doesn’t share DNA

Longitudinal Study

track someone’s progress for years, effective, but long

Cross-sectional Study

Looking at behaviors from different age groups

Critiques

social norms have existed forever, can’t say it is evolution
