Case study

Definition: An in-depth study of one person. Much of Freud's work and theories were developed through individual case studies. In a case study, nearly every aspect of the subject’s life and history is analyzed to seek patterns and causes for behavior. The hope is that learning gained from studying one case can be generalized to many others. Unfortunately, case studies tend to be highly subjective and it is difficult to generalize results to a larger population.


Replication
Definition: A term referring to the repetition of a research study, generally with different situations and different subjects, to determine if the basic findings of the original study can be generalized to other participants and circumstances.
