Case studies can therefore assist psychology by illustrating how a theory could be applied to a person or events and by assisting with the development of hypotheses for more systematic testing, e.g., Piaget’s case studies of the cognitive development of his three children. Observational Research: Accounts of the natural behavior of individuals or groups in some setting. Unless the observation is unobtrusive, there may be some subject reactivity to being observed. This often decreases with time, a process called habituation. Observers cannot usually observe all behaviors all of the time. They may use a behavioral checklist and may also use time sampling or event sampling procedures. It is important to assess observer bias by the use of interobserver reliability. Observational research may also pose ethical problems. These can arise when the behaviors being observed are not public behaviors and when the observer joins a group in order to observe the members’ behavior – participant observation. Survey Research:
