context_page_description: John Ridley Stroop, better known as J. Ridley Stroop, was an American psychologist whose research in cognition and interference continues to be considered by some as the gold standard in attentional studies and profound enough to continue to be cited for relevance into the 21st century. However, Christianity was the real passion of his life; psychology was simply an occupation.
context_section_description: Stroop did the rest of his academic study at George Peabody College in Nashville while also teaching courses at Lipscomb. He received his B.S. degree in 1924 and his M.S. in 1925.
  His doctoral studies at Peabody were focused on Experimental Psychology with a minor in Educational Psychology. His research at the Jesup Psychological Laboratory and his dissertation were under the direction of Joseph Peterson. Stroop's research was built on studies in the early 1880s by Cattell under the direction of Wilhelm Wundt to measure mental processes involving naming objects as well as reading object names. The elegance of Stroop's research was to apply experimental rigor and a clarity of explanation that led to identification of the tested processes with his name. He developed a color-word task to demonstrate interference between reading an object's name and naming an object, and explained some of its psychological characteristics, which were later named the Stroop effect. Soon after producing his dissertation on the color-word task to obtain his Ph.D, he left experimental psychology. He only produced two other papers related to the color-word task.
  After obtaining his doctorate, he worked briefly for the Tennessee Educational Commission and also for the Tennessee Polytechnic Institute, now Tennessee Technological University. He soon returned to David Lipscomb College, where he served as Registrar for eleven years, and then as chair of the Psychology Department from 1948 to 1964. He continued to teach psychology and Biblical studies until he retired in 1967. He served one year as dean of Ohio Valley College in Parkersburg, West Virginia before returning to Lipscomb as Emeritus Professor of Biblical Studies until his death on September 1, 1973.
