Answer:
Most of the training of animals is learned from conditioned response.
Explanation:
A conditioned response is a learned response to a previously neutral stimulus. This is achieved by pairing a neutral stimulus with an unconditioned stimulus, which doesn't require any conditioning to cause a reaction.
For example, the smell of food is an unconditioned stimulus that causes the feeling of hunger. This type of response to food is an unconditioned response. If we paired another stimulus, for example, the sound of a whistle, with the smell of food, this stimulus on its own would eventually start causing hunger. This makes the sound of the whistle the conditioned stimulus and feeling hungry after hearing the sound of the whistle the conditioned response.
Most of the animal training is based on this principle.
