Document Summary
Types of correlational and true experiments: takes groups and follows them overtime as they develop, collecting data from the same people at different times, the only way to actually glimpse and examine development without confounding variables, drawbacks: You need lots of patience to wait until the children actually grow and develop. You may lose participants throughout the study: cross-sectional, separate age groups at the same point in time. Behavioral genetics- focuses on influences that genes have on behavior. Such as iq, athletic ability: nature- genetics, nurture- environment. Includes microsystems: heritability- individual differences due to genes. Genotype- what your genes spell out for you with a set range wiggle room . Phenotype- how a trait is expressed in our life: trait= heritability + environment. 0% = no genetic influence, and all environmental. 100% = environmental influence, and no genetic: genetic influences: Twin studies: type 1- monozygotic twins (identical) reared apart.
