Influences

During Crozier’s time at Harvard, students became interested in him and his work, particularly in the general physiology lab. This helped Cozier gain more lab support. Crozier was exploring the ways in which different environmental forces could have an effect on an organism's behaviour, which he and Skinner both understood as the study of reflexes. Skinner studied entire unharmed organism's behaviours instead of studying their reflexes by opening the organism and viewing mechanisms separately. He was influenced by Loeb who always talked about studying organisms without surgically harming them, and instead looking at them in their entirety. Skinner was able to go through with his studies on this topic by being under the watch of William John Crozier. and influenced B.F. Skinner and the field of psychology. Crozier's research also spanned to the United Kingdom where the British Journal of Ophthalmology published an obituary highlighting his research having influenced the Institute of Ophthalmology in London.
