Question: From what university did the person McGeoch studied under at the University of Chicago graduate? Passage 1:McGeoch was born on October 9, 1897 in Argyle, New York. He received his bachelor's degree from Westminster College in 1918, and a master's degree from Colorado College in 1919. His master's thesis, titled "The Present Status of Psychology", is a review of the history of the field of psychology and how the role of psychology was viewed in the early 20th century. He then studied under Harvey A. Carr at the University of Chicago. He studied a variety of topics while at the University of Chicago, including suggestibility and intelligence in delinquents, time perception, neuropsychological and vocational testing, and the reliability and validity of the Pressey X-O test. His doctoral dissertation was titled "A study in the psychology of testimony." Following the completion of his dissertation, McGeoch’s work primarily focused on human learning and memory. Harvey Carr significantly influenced McGeoch’s work, and provided feedback on the McGeoch's introductory textbook on human learning, The Psychology of Human Learning, which was published after Carr’s death in 1943. McGeoch completed his PhD while he was a faculty member at the University of Washington. He accepted a full Professor position 2 years later at the University of Arkansas. In 1930 he moved to the University of Missouri where he became the chair of the department of psychology. He held this position for 5 years before moving to Wesleyan University, where he was also chair of the department from 1935–1939 and was awarded an honorary degree in recognition of his accomplishments as a lecturer and administrator. In 1939, McGeoch moved to the University of Iowa, where he also chaired the department. He died in Iowa City on March 3, 1942 from a cerebral hemorrhage.
 Passage 2:There was one driver change heading into the race. Having been in one of the Aguri cars since the first round of the season in Beijing, António Félix da Costa missed the ePrix because of a Deutsche Tourenwagen Masters commitment at the Red Bull Ring and was replaced by endurance racing driver René Rast. The deal was confirmed in the week before the race and was originally slated to be World Endurance Championship driver Adam Carroll but the agreement fell apart. It marked Rast's first participation in single-seater machinery since the Formula BMW ADAC in 2004 and practised on the team's simulator to familiarise himself with the car. Oliver Turvey was set to be replaced by the Formula Renault 3.5 driver Ben Hanley because of a Super GT commitment at the Autopolis circuit, but that race was postponed because of the Kumamoto earthquakes, and his Formula E seat was reinstated.
