Bechterev was a reflexologist who also sought a completely objective psychology. Unlike Pavlov, who studied internal reflexes such as salivation, Bechterev studied overt behavior. Bechterev believed that his technique was superior to Pavlov’s because it required no operation, it could be used easily on humans, it minimized unwanted reactions from the subject, overt behavior could be easily measured, and satiation was not a problem. The type of reflexive behavior later studied by U.S. behaviorists was more like Bechterev’s than Pavlov’s.
