Nature - Nurture Issue
The longstanding controversy over the relative contributions that genes and experience make to the development of psychological traits and behaviors. Today’s science views traits and behaviors as arising from the interaction of nature & nurture
Natural Selection
The principle that the inherited traits enabling an organism to survive and reproduce in an environment (in competition with other trait variations) most likely be passed on to succeding generations. Ex: Survival of the BEST PREPARED.
Evolutionary Psychology
The study of the evolution of behavior and the mind, using principles of natural selection.
Behavior Genetics
The study of the relative power and limits of genetics and environmental factors influencing behavior
Mutation
A random error in gene replication that leads to a change
Environment
Every nongenetic influence, from prenatal nutrition to our experiences of the people and things around us.
Heredity
The genetic transfer of characteristics from parents to offspring
Genes
The biochemical units of heredity
Genome
The complete instructions for making an organism
Identical Twins (monozygotic)
Individuals who developed from a single fertilized egg that split in two, creatin two genetically identical organisms.
Fraternal Twins (dizygotic)
Individuals who developed from separate fertilized eggs. They are genetically no closer than ordinary siblings, but they shared a prenatal environment.
Interaction
The interplay that occurs when the effect of one factor (such as environment) depends on another factor (such as heredity)
Epigenetics
“above” or “in addition to” (api) genetics the study of the molecular mechanisms by which environments can influence genetics expression (without a DNA change) Ex. non expressed traits being later shown E.h. Schizophrenia
