Question

Quizplus · Accepted Answer

A case study involves in-depth investigation and analysis of a single individual or case, which is exactly what the psychiatrist is doing with the client with multiple personalities. A controlled experiment and single-blind study involve manipulating variables and comparing outcomes between different groups, which is not relevant to this scenario. Psycho-history refers to studying the psychological factors that have influenced historical events or people, which is also not applicable here.
