Who trained dogs to salivate at the ring of a bell?
Ethology stimulus. The first studies of associative learning were made by Russian physiologist Ivan Pavlov, who observed that dogs trained to associate food with the ringing of a bell would salivate on hearing the bell. Imprinting enables the young to discriminate the members of their own species, vital for reproductive success. This important type of learning only takes place in a very limited period of time. Lorenz observed that the young of birds such as geese and chickens followed their mothers spontaneously from almost the first day after they were hatched, and he discovered that this response could be imitated by
Meta-communication had learned that the ringing of the bell signaled "food is on the way" in his experiment in which dogs were trained to salivate upon hearing a bell ring. This was accomplished by ringing a bell just prior to feeding the dogs. After repeating this procedure for some time it was found that the dogs would salivate after hearing the bell - without the need for food being presented. Something that is not often discussed in context with this experiment is the fact that the dogs would not salivate unless they were wearing a special harness. When exposed to the
