Summary
A modification of Petropavlovskii's method of studying motor defense conditioned reflexes is suggested. A seven-point scale is employed for better evaluation of conditioned-reflex activity, taking into consideration the relationship between the quantitative and qualitative indices of the conditioned motor reaction, and for comparison in graphic form of the results of experiments by the same motor method. To create more natural experimental conditions for the animal, the author suggests a system in which the animal, by raising its paw, turns off both the unconditioned and conditioned stimuli, and simultaneously turns on an illuminated translucent shield, which plays the role of a correcting signal.
