Case Study
A case study is an observational research method involving an in-depth, and often longitudinal, examination of an individual, social unit, or event. In psychology, case studies typically provide a detailed qualitative description and analysis of a single individual, frequently one who has a rare condition, unusual disorder, or specific brain damage. While they primarily rely on qualitative tools like interviews and naturalistic observation, case studies can also incorporate quantitative data such as psychological testing or physiological measurements.

To judge which approach provides the necessary intensive, multi-dimensional profile required for this rare scenario, the researcher should select a(n) _____, as naturalistic observation would fail to provide the exhaustive depth of detail needed to understand such a unique case.
The two primary types of observational research in psychology are clinical (or case) studies and _____ observation.
A developmental psychologist is deciding between conducting a naturalistic observation of children's play patterns on a public playground or a clinical/case study of a child with a newly identified genetic mutation affecting social development. If the psychologist needs to analyze these methods to maximize ecological validity (the extent to which findings generalize to real-world settings), naturalistic observation is the appropriate choice because it examines behaviors in their natural environment without researcher intervention, whereas a clinical/case study typically focuses in-depth on an individual, sacrificing generalizability for detail.
