Document Summary
Research methods review: observational: watch natural life, naturalistic observation: observe behavior in the natural environment, without going in with a hypothesis. Just describe behavior: correlational: have a specific idea about 2 variables, so predict behavior based on the relationship between 2 variables and observe this relationship (cid:894)(cid:272)a(cid:374)"t e(cid:454)plai(cid:374) relationship, experimental: manipulate variables. Having more resources will cause preschoolers to share more: design of experiment: one day, give child large number of blocks. Next day, give child small number of blocks, and see how amount of sharing changes. Identifying variables: a researcher wants to know if a new phone app can help people read faster.

More active brain areas usually have more oxygen levels.
