Walter Richard Miles

Miles began working as a research scientist at Wesleyan College after receiving his PhD. He was recruited by Raymond Dodge to fill a one-year position here while Dodge left to work with F.G. Benedict at the Carnegie Nutrition Institute.[6][9] When his year was up, he replaced Dodge at the Carnegie Nutrition Laboratory in Washington, D.C., where he remained until 1922.[6][10] During his time here, much of his research focused on combined psychological and physiological measurements[6] His work was heavily influenced by the apparatus and experimental records Dodge had left behind. One notable area of research while at Carnegie was Miles' work on the reaction time of football players in collaboration with his graduate student Bernice Courtney Graves who was better known as B.C. Graves.[11][12][13] In line with Miles' love of apparatuses, the two constructed an apparatus to measure the effects of variations in signal calling on the speed at which the lineman moved in reaction to the signal for snapping the ball[9]

While at the Carnegie Nutrition Laboratory, Miles was inspired by Dodge's work and conducted a host of important research on the psychological effects of low and moderate dose alcohol. Miles created various apparatuses to test the effects of alcohol including the pursuit pendulum[14] to measure eye motion and response times of intoxicated subjects.[15][16] Psychologist C. James Goodwin reviewed Miles' work on alcohol research in a 2014 publication in the History of Psychology journal.[16] Goodwin noted that Miles published several papers and technical reports on this work. However, most notably Miles compiled a 298-page monograph in 1924 detailing five sets of studies that spanned over 10 years.[17] He first examined the effects of moderate doses of alcohol (i.e., 14%–22% by weight) on behavior and demonstrated that this impairs motor skills. Specifically, he gave five male participants moderate doses of alcohol and demonstrated that alcohol reduces typing efficiency, finger movement speed, and horizontal eye movement speed. Miles came up with a novel method of disguising placebo beverages in this study that is still used today: wiping the rim of the glass with alcohol. In the second study, Miles used similar methodology as the first study with the exception of giving participants alcohol after eating a full meal to see if food diluted the effects of alcohol. It reduced adverse effects, but still impair performance. In the third study, Miles collaborated with T. M. Carpenter to examine the effects of alcohol administered via rectal injection during sleep. Rectal injection of either alcohol or a saline solution was used to ensure the participant did not know if he was being administered alcohol or a placebo, and because it was believed that alcohol would be absorbed more quickly into the bloodstream than by oral administration. In the fourth study, Miles examined the effects of low dose alcohol on behavior by conducting a series of studies of two years with a 36-year-old male. This study lead to the fifth set of studies that further examined low dose alcohol using 8 subjects between the ages of 22 and 52. Collectively, this work gained Miles notoriety in the alcohol field and he became in expert in the field. Miles' research on the effects of alcohol in the 1920s was fitting given the debate about alcohol that led to National Prohibition.[16] In 1917 before prohibition went into effect in 1920, President Woodrow Wilson cut the grain allotment to brewers and distillers maintaining that beer be reduced so that it could not contain more than 2.75% alcohol by weight, which is about 3.44% by volume today.[16] There was much debate about this with drys saying that this was insufficient and alcohol should be banned altogether and with wets saying that small doses cannot have negative effects. Miles, who occasionally drank himself, was supportive of Prohibition and was suspicious of the wets claim. He started examining low doses of alcohol in 1919 right before prohibition went into effect.[16] Additionally, with the start of World War I, he became involved with war-related projects and, in collaboration with Dodge, designed gas masks and studied the effects of severely restricted food intake.[6][18] However, the war had severed many relations Carnegie Laboratory had with researchers in Europe. As such, physiologist/chemist Francis Benedict chose Miles to reestablish important connections across Europe.[16] As such, from April to August 1920 Miles visited 57 psychology and physiology laboratories and institutes across Europe to observe, record, and interact with researchers. The culmination of this trip was an unpublished 300-page detailed report of Miles' observations.[19] This report was made available to the Archives of the History of American Psychology at the University of Akron and in September 2010 C. James Goodwin and Lizette Royer made this work available in print.[19][20]

Although Miles was happy at Carnegie, he missed teaching and the academic environment he briefly experienced in his year at Wesleyan. Thus, when Lewis Terman offered him a position at Stanford University in Palo Alto, he readily accepted.[16] Not surprisingly, he continued researching a variety of topics and developed a range of apparatuses including the two-story rat maze while at Stanford.[21] In fact, after Miles left to take a position at Yale University, Ernest Hilgard replaced him at Stanford University and noted "I found the open laboratory space literally packed with devices ready to be operated, reminding me of a modern science museum."[6] However, Miles is probably best known for his studies on human development in later stages of life that became known as the Stanford Later Maturity Studies.[6][9][16] Indeed, this work helped him build a reputation among his peers and led to his nomination and election as president of the American Psychological Association in 1932.[16][22] This study included over 2,000 subjects from ages 6 to 95 who completed questionnaires, reaction time tasks, motor skills tests, and various anthropometric and physiological measures.[6]

Miles first came to Yale in 1930 before returning to Stanford in 1931. He came to Yale at the request of Dodge who asked Miles is there was "any possibility of inducing you to come here in a position parallel with mine with the expectation that within a few years you will take my place".[23] Dodge was suffering from Parkinson's disease and wanted Miles to take over.[6][16] In 1932 Miles made Yale his permanent place of work before reaching the mandatory retirement age over twenty years later in 1952.[6] GRAND. Although his appointment was primarily at the Department of Psychology, his affiliation with the Medical School influenced his research AJ[6] His early years at Yale were focused on publishing his findings from the Stanford Later Maturity Study.[6][24] His work published from data collected at Yale were minor and highly specialized [6][24]

However, when World War II began Miles again became involved in war-related projects. He made one of the best contributions to aviation psychology when he discovered that while waiting to be called for flights, aviators could wear red-lensed goggles. These goggles helped with dark adaptation and could be worn at night so that flyers would immediately be ready for emergency flying when calls came.[6][24]

Despite Miles' retirement from Yale, he remained active in psychology. Ernest Hilgard heard about a visiting psychologist position at the University of Istanbul and recommended this to Miles given his love of travel.[24] Miles took the position of Professor of Experimental Psychology and created and developed a laboratory there.[16] Although his wife Catharine was also offered a position,[25] she declined. Most notably, Miles supervised a dissertation of a woman who eventually accepted a position on the teaching staff there and the two edited a volume called the Istanbul Studies in Experimental Psychology.[6][24]

At the age of 72, Miles accepted a position as scientific director of the Submarine Base at New London, Connecticut, where he stayed for eight years.[6][16][24] His work here included studying problems associated with living together in cramped quarters as well as the effects of long exposures to cold.
