Chapter 12 Psychology Notes:
Major issues and methods
o Are you the same person now than age 14?
o How will you be 5 years from now?
o Developmental psychology- how do we change over our lifespan
o Our ability from changing from a zygote, to other development of walking and running
o EXAM QUESTION- the difference between a critical period and a sensitive -====
o Nature vs. Nurture
o Twin studies- figure out how much is genetics, and how much is environments
o Critical – around puberty have to be exposed vs, sensitive- optimal range of time to learn
o Language acquisition
o How these things change over time, whether it is continuous- increase in ability? or
change all of a sudden, does it happen all of a sudden? Crawling to walking?
Developmental functions- how processes change
o No change
***see graph in text book****
o Patterns of various forms of developmental functions
o Cohort- group born at the same time
o Cross sectional- compare different ages at same time
o Longitudinal- test same cohort at different times- usually doesn’t work, far too time
o Sequential- test several cohorts as they age.
Research Designs Pros And Cons
o Cross sectional
These people didn’t go through the same things in their lives. So visual acuity,
we can test people at teen ages
