PSY 113 Lecture Notes - Lecture 5: Nikolaas Tinbergen, Greylag Goose, Konrad Lorenz
Document Summary
Developmental psychologists study changes in behavior, attitudes, and mind--- as a function of time (both quantitative and qualitative changes) What causes these changes: genetic inheritance, environmental factors. The european ethologists (e. g. , k. lorenz & n. tinbergen)- nature, animals in natural habitat. Universal and stereotypical, therefore said to be due to nature !! E. g. , monozygotic twins reared in different homes but adopted children may not be representative of the larger population : compare concordance rates for co-twins- quiz. E. g. , if concordance rate of mz twins is higher than dz twins, then there is a strong genetic influence on development but mz twins look alike. In general, teasing apart the relative influences of gen. & env. requires multiple methods!! Fertilization- if all goes well, cell division results in a 100-trillion cell person. Identical in every cell of the body, expect sperm & ova which have half of genetic material.
