Thank you Rena! -Pavlov's dog

Rena sent us a mail about Pavlov's dog as follows.
Thank you!

i'm 2nd year psychology student.I think the dog was salivating without a food because the dog was adapting the sound of a bell. The dog was influence of the things around it.but finally the realize that when the bell sound there's no food at all.
