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 McGeoch's introductory textbook on human learning, The Psychology of Human Learning, which was published after Carr's death in 1943.
