Answer:
c) identifying the bell as a neutral stimulus; identifying food as the unconditioned stimulus; repeatedly presenting the sound of the bell followed by food; presenting the sound of the bell to produce saliva.
Explanation:
Russian physiologist Ivan Pavlov was studying salivation in dogs during the 1890s and comes up with the theory of classical conditioning in which a neutral stimulus was closely associated with the unconditioned stimulus to obtain a particular conditioned response. the theory involves learning to combine an unconditional stimulus that has already given rise to a specific response with a new stimulus so that the new stimulus results in the same response.
