Stratton began his career working in a philosophy department, teaching philosophy courses, but branched into experimentation soon after. He tackled problems of sociology and international relations later in his career.
Wundt's lab and the inverted-glasses experiments Stratton went on to become a first-generation experimentalist in psychology. Wundt's lab in Leipzig, with experimental programs bringing together the fields of
evolutionary biology, sensory physiology and nervous-system studies, was a part of the career of most of the first generation. It was the exposure there, added to the graduate work at Yale, that influenced Stratton into becoming a psychologist. It was there that he started his binocular vision experiments as well. In these experiments, he found himself adapting to the new perception of the environment over a few days, after inverting the images his eyes saw on a regular basis. For this, he wore a set of
upside down goggles, glasses inverting images both upside-down and left-right. Stratton wore these glasses over his right eye and covered the left with a patch during the day, and slept blindfolded at night. Initial movement was clumsy, but adjusting to the new environment took only a few days. Stratton tried variations of the experiment over the next few years. First he wore the glasses for eight days, back at Berkeley. The first day he was nauseated and the inverted landscape felt unreal, but by the second day just his own body position seemed strange, and by day seven, things felt normal. A sense of strangeness returned when the glasses were taken out, though the world looked straight side up; he found himself reaching out with the right hand when he should have used the left, and the other way around. Then he tried the experiment outdoors. He also tried another experiment disrupting the mental link between touch and sight. There he wore a set of mirrors attached to a harness as shown in
the figure allowing, and forcing, him to see his body from above. He found the senses adapted in a similar way over three days. His interpretation was that we build up an association between sight and touch by associational learning over a period of time. During certain periods, the disconnect between vision and touch made him feel as if his body was not where his touch and
proprioceptive feeling told him it was. This out-of-body experience, caused by an altered but normal sensory perception, vanished when he attended to the issue critically, focusing on the disconnect.
Berkeley psychology department Back at Berkeley from Johns Hopkins, Stratton stayed in the philosophy department as its second faculty member and first psychology specialist until the psychology department broke off in 1922. The new department started with four people: Stratton as chair;
Edward Chace Tolman, with a Harvard degree, and an initiator of rodent experiments soiling the rooms of the philosophy department and hastening the split of the psychology division; Brown, Stratton's earlier student and Berkeley faculty member from 1908 onward; and
Olga Bridgman, the first Berkeley psychology PhD awardee, albeit from the philosophy department. Before the split Stratton had set up Berkeley's first psychology lab in the philosophy department and taught psychology courses with Brown. The courses included sensation, perception, emotion, memory, and applications of psychology to professions such as law, medicine, schooling and clerical work by priests. Stratton continued his experiments on perception, branching into studies on
pseudoscopic vision,
stereoscopic acuity, eye movements, symmetry and visual illusions, how people perceive depth seeing surroundings either one-eyed or two-eyed, acuity and limits of
peripheral vision, apparent motion, afterimages impressed on the eye when a person stares at an object for long and then looks away, and problems with sight in half the visual field (
hemianopsia). He both reviewed earlier studies on motion and conducted two of his own, concluding perceiving movement was more than the sum of seeing successive sequential images. He also surveyed and reported in reviews in the
Psychological Bulletin experiments at various labs, including those in Europe, on matters related to sensation and perception. • Philosophical Union: "The import of psychological experiments" (series), 1899–1900 •

Philosophical and educational psychology and sociology Stratton was exposed to multiple influences through his life. As an undergraduate student of Howison, he learned about philosophy and religion. At Yale and later at Wundt's lab, he switched to experimental psychology and studied perception, memory and emotion. His exposure to World War I, serving in the Army then, focused his mind on issues of war and peace and international relations. Stratton's later work reflected these elements of his experience. He was also a scholar of the classics and translated some Greek philosophers. Stratton saw humans not as machines to be analyzed mechanistically, but also as seating will, emotion and drives, all of which had to analyzed as scientifically as the traditional psychological concepts of sensation, perception and memory. He also believed in a supreme actuality behind the world registered by our senses. This was the theme of his last published book,
Man-Creator or Destroyer, completed in 1952 when he was eighty-seven years old. His book
Developing Mental Power was a foray into educational psychology, addressing the question of general versus specific training in terms teachers could understand and use. Stratton aimed at this goal via a simple and generally applicable look at the basic workings of mental life.
John F. Dashiell, writing in the
Journal of Abnormal Psychology, found this a failure. Dashiell saw the path from the psychological concepts—emotion, intelligence, and will—to teaching methodology, not clearly described in the book. Stratton also applied psychological concepts to figure out how to avert war. He was optimistic it was possible to harness the creative and destructive facets of individuals to get nations to coexist peacefully. He saw nations as consisting of ethnicities and races which had to coexist in harmony. In line with the prevailing view in his field, he did not see the races as inherently equally intelligent.
Psychology of religion and emotions Stratton also contributed to the psychological study of religion. Along with other founders of the
psychology of religion, he saw religion as including both personal faith and historical traditions. He used religious texts as supporting data. In
The Psychology of the Religious Life he explored the epics and
sacred texts of a large set of ethnicities to understand the traditions and rituals symbolizing the concrete parts of faiths to understand the goals and concept of religion as a whole. His psychology sought to explain how our need to grasp, accept and live with conceptual opposites such as the sublime and the devilish, the humble and the proud, and the docile and the energetic, led us in the direction of religion. He also tied human emotions, especially anger and pugnacity, to religious faith. To understand the linkage, Stratton collected data on religious writings and the rites and traditions of civilizations then considered not as advanced. In
Anger: Its Religious and Moral Significance he listed exhaustively and studied the major religions of the world and classified them into three categories. The combative religions, such as
Islam, per him, glorified anger, while those such as
Buddhism were "unangry".
Christianity he saw as an example of an anger-supported-love–based religion. He concluded
Western civilization was trending toward denying rage as good and accepting love and goodwill as desirable, but cautioned anger was at times needed to fight evil. As a professor at Berkeley, Stratton visited
Philippines,
China,
Japan, and
Hawaii, coordinating with the
University of the Philippines to study the psychology of both races and
oriental religions. He also explored anger and emotions in animals. He was one of the scientists who were invited to attend, and confirmed attendance, at a conference to discuss human emotions and feelings. The conference, scheduled for October 21–23, 1927, at
Wittenberg College was to focus on the experimental psychology of religion. Stratton articulated his own beliefs about religion as well. He did not subscribe to the view religious feeling was primarily a social need, believing it to be a need for seeing a cause and logic to the world along with a harmony to things. A believer in
dualism, he held the theory of a separate biological psyche and something beyond it. To him the most important aspects of the psyche lay beyond objective science, at least in his time. He sought to explore those boundaries where the methods of science had to stop and declare what was beyond as unknown, limited by the tools of the times. In
The Psychology of the Religious Life he laid out his definition of religion as an appreciative feeling toward an unseen entity marked the best or the greatest. Stratton suggested music had healing powers. In an address on the "Nature and training of the emotions" delivered to a group of nurses at the Baltimore hospitals, he predicted music would be used to treat the sick in the future, and held that nurses had to know how to sing to patients under their care. == Books ==
