APPARATUS FOR EQUATING MOTION AND CONSEQUENT VISUAL FEEDBACK FOR A SELF-PROPELLED (A) AND A TRANSPORTED (P) KITTEN
Physical Therapy, May 1972, Elizabeth J. Davies, Ed.
All of the animals in both A and P conditions were observed daily for the presence of certain visually controlled responses, known to be absent when dark-reared kittens are first brought into light.
One test determined whether an eye blink occurred when the experimenter's hand was brought swiftly toward the kitten's head; a behavior observed in normally reared animals.
A second test consisted of carrying the kitten obliquely downward toward a laboratory table at a slow rate.
