UNIT 1 aos 2 - nature-nurture influences Flashcards
define genes
the basic unit of genetic material located on the chromosomes
define recessive
describes a gene whose characteristics will only be displayed if the paired gene is also recessive (not dominant)
define dominant
the gene that displays its characteristics rather than its paired (recessive) gene.
define interactionist approach
the assumption that hereditary and environmental factors interact to influence developmental change.
define nature
effect of genetic and inherited factors on the behaviour of individuals
define nurture
effect of environmental factors on the behaviour of individuals
what is the importance of twin studies
twin studies are used to determine if nature or nurture has a greater influence on development. this is because some twins are separated at birth, therefore we can blame similarities in characteristics, such as intelligence, on biological factors, so nature.
what is the importance of adoption studies
adoption studies are used to determine the effect of nurture on development. it involves children who were adopted and therefore have no genetic similarity to their adoptive parents.
