Sensory perception in animals is a major preoccupation in the psychology laboratories of the University of Rochester. There young John Warkentin, by recording the eye movements of animals placed inside a striped, revolving cylinder, has tested visual acuity in such difficult subjects as snakes, frogs, toads, turtles, alligators, gophers, Gila monsters. Some months ago Rochester's psychology department chairman, Dr. Leonard Carmichael, left to become president of Tufts College. He was replaced by trim, twinkly, soft-spoken Elmer Augustine Kurtz Culler, formerly of the University of Illinois, who has made profound studies of the "conditioned response" and whose specialty...
...method of testing animals' eyesight is to train them to respond to certain visual stimuli. This is laborious, and in the case of some refractory creatures, such as snakes, frogs and Gila monsters, virtually impossible. At the University of Rochester a promising, extravagantly polite young scientist named John Warkentin is investigating animal eyesight with a more efficient technique which requires no training, last week made public some of his findings...
...progressively diminished until the animal stops turning its eyes- thus showing that its threshold of vision has been reached. For sharp-eyed creatures which can easily follow the the 1/16th inch stripes, a further refinement is achieved by using slender threads, the finest of which were especially woven for Warkentin's experiments. The cylinder technique was used in Germany 15 years ago, but only to study reflex eye movements and not to test acuteness of vision. Its adaptation to Warkentin's purposes was suggested by his departmental superior. Dr. Karl Ulrich Smith. Since Mr. Warkentin's animals...
...John Warkentin was born 25 years ago in Hamburg, Germany, son of a Russian Mennonite preacher and teacher who took a Ph.D. at the University of Chicago and is now a professor of German literature at Bethel College. The elder Warkentin is currently trying to have the Supreme Court pass on his application for citizenship, which has been refused because, abiding by the tenets of his religion, he will take no oath to bear arms. Son John will take no such oath either. He studied at Brown University under Dr. Leonard Carmichael, went along with Carmichael to the University...
