Case Studies and Small-n Experimental Studies
Chapter 10 of our text (Shaughnessy, Zechmeister, & Zechmeister, 2009) focuses on a SPECIFIC type of methodology. It uses only one participant (case study) or one subject (small-n single-case experimental study).Whereas the case study is a descriptive design, small-n studies study one subject (usually) but within experimental design methodology.
This means case studies are a description of something (they are qualitative research because they do not attempt to analyze data with numbers). Single case experimental designs, on the other hand, are a regular experimental design BUT using only one subject or a small number of subjects or one group that is treated as one subject.
To illustrate this, how about going to the library in one of the psychological databases (e.g. Proquest, PsycINFO, etc.) or going to Google Scholar and finding an article that reports on either a case study or a small-n experimental design study?
Share with us a brief synopsis of the article and a reference so we can all look it up if it’s of interest, or a link to the article.
What was the value of the study? How did it help the field of psychology and its knowledge base?
I hope some of you at least will choose to do this little project so we can use them as starting points for discussions about these two methodologies.
