Dr. Okawa is interested in studying the effect that neurological trauma can have on short-term memory. First, he collects detailed information from a small number of individuals who have experienced brain damage. Then, using information provided by medical records, interviews, and observations, Dr. Okawa attempts to create an in-depth portrait of each individual. What type of research method was used in this study?

The answer is case study.

Explanation:

A case study is a research method that focuses on a single person, group of people or event. These in-depth observations can be generalised to similar cases, which are useful to predict future outcomes.

The greatest advantage of case studies is that they are often inexpensive and highly reliable. For this reason, they are especially convenient for social sciences such as sociology and anthropology, although they are often used in medicine and psychology.
