Final answer:
Psychoanalysts, unlike other groups of psychologists, did not develop their theories primarily in academic and laboratory settings, but through clinical practices such as in-depth interviews and case studies.
Step-by-step explanation:
The group of psychologists who did not develop their ideas primarily in academic and laboratory settings were the psychoanalysts. Psychoanalysis, as a discipline, is closely associated with Sigmund Freud, who developed his theories through in-depth interviews and case studies, often in clinical settings. This is distinct from behaviorists, cognitive psychologists, and humanistic psychologists, many of whom formulated and tested their theories within more controlled academic and laboratory environments. Behaviorists like Pavlov, Watson, and Skinner conducted experiments to study conditioned responses and behavior. Cognitive psychologists are interested in understanding how people think and process information, and humanistic psychologists like Maslow and Rogers focused on personal growth and potential, often in more applied, real-world settings compared to laboratory studies.
