Edwin Ray Guthrie (; January 9, 1886 – April 23, 1969) was a behavioral psychologist who began his career as a mathematics teacher and philosopher. But, he became a psychologist at the age of 33. He spent most of his career at the University of Washington, where he became full professor and then emeritus professor in psychology.Guthrie is best known for his theory that all learning is based on a stimulus–response association. This was variously described as one trial theory, non-reinforcement, and contiguity learning. The theory was:

"A combination of stimuli which has accompanied a movement will on its recurrence tend to be followed by that movement".One word that his coworkers and students used to describe Guthrie and his theories was "simple", referring to how he described complex ideas in simple terms. Some critics have considered his teaching style defective, with one claiming that "...many reviews of Guthrie in the literature have mistaken incompleteness for simplicity".
