Document Summary
Developmental psychology - the study of age-related changes in behavioural and cognitive process. Stage changes - is our development linear or in stepping blocks? (continuous vs. discontinuous beliefs) Research designs: cross-sectional design: different age groups compared at one time (what is the difference between the age groups?) Cons: cohort effects - differences that can occur between subjects (e. g. history, technology, attitude: longitudinal design : the same participants are studied over time (what is the difference over this person"s lifespan?) Cons: those involved could drop-out, cost, very time consuming. Third design gets around the weaknesses of cross-sectional and longitudinal designs: sequential designs - takes more than 1 group overtime, mixing both of the previous designs. Prenatal development: germinal (first 2 weeks) - when the zygote moves and attaches to the uterus wall (endometrium, embryonic (2-8 weeks) - placenta and umbilical cord formation.
