Unit 3C Flashcards
What types of questions interest behavior geneticists?
If our attributes are contributed to our genes or environments
Non-genetic influence from pre-natal nutrition and stuff around us
Environment
Study of relative powers and limits of genetics and environmental influences on behavior
Behavior genetics
Threadlike structures of DNA that contain genes
Chromosomes
Molecule containing genetic information making up chromosomes
DNA
Biochemical units of heredity that make up chromosomes; segments of DNA capable of protein synthesis
Genes
Complete instructions to make an organism
Genome
Describe how twin and adoption studies help is differentiate hereditary and environmental influences on behavior
Since twins are genetically identical, scientist could test if behavior is caused by genes or environment
Twins who develop from one zygote that splits into 2
Identical twins
A persons emotional reactivity and intensity
Temperament
Variation among individuals we can attribute to genes
Heritability
The effect of one factor depends on another factor
Interaction
Twins who come from separate zygotes
Fraternal twins
Things in the environment that can change us
Nature vs nurture
Study of molecular structures and functions of genes
Molecular genetics
What area of psychology interests evolutionary psychologists?
How humans are alike based on natural selection
What are some possible effects of natural selection in the development of human characteristics?
Helps us to survive and adapt
Study of the evolution of behaviors and mind using ideas from natural selection
Evolutionary psychology
Inherited trait variations that lead to an increased relate of survival and reproduction
Natural selection
Random error in gene replication
Mutation
What are some criticisms of evolutionary explanations on human behaviors?
Underestimating culture, learning. Only look at nature not morals
