Describe how ivan pavlov used classical conditioning to study salivation in dogs.

Pavlov used proved his theory of classical conditioning by studying salivation in dogs. He observed an unconditioned response, the salivation, that was a consequence of an unconditioned stimulus (the meat). Then, he paired the unconditioned response with a neutral stimulus (the sound of a bell), by giving the dog the meat after ringing the bell. He found that after being conditioned, the dog salivated every time he heard the bell ring, the salivation was now a conditioned response.

countries such as spain, france and portugal colonized the region. although most of latin america was colonized by spain, the countries of portugal and france also had major influences on the region. due to war and disease, native populations were decimated.
