Walter Samuel Hunter

Walter Samuel Hunter (1889-1954) was an American psychologist who pioneered behaviorism by emphasizing the observation of animal behavior over subjective mental processes. He earned his Ph.D. from the University of Chicago in 1912 with a thesis on delayed reaction in animals and children, held key positions at Clark University and Brown University, and founded Psychological Abstracts in 1927. Hunter advanced psychology as a science through experimental work on learning, memory, and genetic psychology.
