Answer:
In classical conditioning terms, rattling the box is a stimulus and your dog's salivation to the rattling is a response.
Explanation:
According to classical conditioning theory, first researched and developed by Russian psychologist Ivan Pavlov (1849-1936) in the 19th century, we learn to behave in certain ways by associating a given stimulus to a particular response through repetition. Since conditioning can be used to shape the behavior of both human beings and animals, it was an important contribution to the field of behavioral psychology.
