In some places, Pavlov refers to an electric bell as a different stimulus than a buzzer. Maybe like a doorbell rather than a hand bell, but this fretting about "bell" has alway seemed silly.
>>> Rick Froman <[email protected]> 11/18/2014 4:32 PM >>> I believe the point of the author in saying that no *bells* were used (and this is not contradicted by either of the examples cited below), was that there were none of the prototypical handbells you always see pictured in textbooks. A proper translation would be to refer to the bells as electronic buzzers (and in fact that is the image given by a reading of the examples provided below). Maybe this is a regional thing and there are places where the word *bell* evokes the sound of an electric buzzer but most of those hearing *bell* seem to interpret it as the metallic object with a clapper in the middle that is moved to produce a sound. The author*s point was that the discrete sound of a handbell would not have been to Pavlov*s purpose of making a continuous sound for the most effective CS. The use of the word *bell* can still lead to some confusion today on that point. People imagine a dog hearing a bell once and then sometime later tasting the food. Pavlov*s buzzer CS, on the other hand, would actually continue to buzz until the food was delivered (delayed conditioning) instead of being a discrete one time stimulus (even in trace conditioning, the CS would probably last longer than the single ring of a bell).

There are more. "I shall describe first an experiment conducted by Dr. Frolov illustrating the development of a secondary conditioned reflex: A [p. 34] dog has two primary alimentary conditioned stimuli firmly established, one to the sound of a metronome and the other to the buzzing of an electric bell. . ," >>> "Michael Scoles" <[email protected]> 11/18/2014 2:39 PM >>> Bells were used, at least in attempts to produce backwards conditioning. "With another dog the loud buzzing of an electric bell set going 5 to 10 seconds after administration of food failed to establish a conditioned alimentary reflex even after 374 combinations, whereas the regular rotation of an object in front of the eyes of the animal, the rotation beginning before the administration of food, acquired the properties of a conditioned stimulus after only 5 combinations." Conditioned Reflexes (1927) Hard to believe that was the only time a bell was used. Michael T.
