Document Summary
What is developmental psychology: the study of age-related changes in behavioral and cognitive processes. Issues: nature vs. nurture, genes vs. upbringing, critical and sensitive periods, stability vs. change, continuous vs. Cross sectional design: different age groups compared at one time, find differences between age groups, pros, cheaper, one shot method, cons, cohort effects, history, technology, attitude difference. Longitudinal design: the same participants are studied over time, differences over their life, pros, controls for historic change, cons, drop outs and cost. Sequential design: third design to get around some weaknesses of the two, takes more than one group over time, helps with cohort differences, but more costly. Physical developments: maturation, the programmed biological process that governs our growth, follows 2 major principles, cephalocaudal principle, proximodistal principle. Sex determination: genes stored in chromosomes, 46 total, 23 pairs, 1 of these pairs is the sex chromosome, xx = female, xy = male.
