Although Howard Scott Liddell is not among the leading figures of American Psychology, his contributions to the study of conditioned reflex and experimental neurosis were significant. Under the influence of the Scottish endocrinologist Sutherland Simpson, Liddell started to study maze learning in sheep and goats without thyroids gland. These experiments did not find significant differences in learning between thyroidectomised and normal animals. Therefore, Liddell turned to the conditioned reflex method, and in 1924 he founded and directed one of the first American laboratories dedicated to the study of conditioned reflex in ruminants. In this paper, we will explore Liddell’s experiments and his ideas about the traumatizing nature of this technique. Finally, we will show that Liddell’s use of reflex conditioned method did not commit him to endorse Pavlov’s physiological ideas. On the contrary, Liddell’s ideas were based on the theory defended by W. B. Cannon.
