A person rattles the box of dog's biscuits before giving the biscuit to dog. As the person rattles the box the dog begins to salivate. Thus rattling of box is _____; and the salivation of dog is a kind of _______.

  • A.CS ; CR
  • B.CS ; UCR
  • C.UCS ; CR
  • D.UCS ; UCR

Answer: A

The rattling of the box is a conditioned stimulus (CS), and the salivation of the dog is a conditioned response (CR). The rattle has been repeatedly paired with the biscuit, which is the unconditioned stimulus, and now produces salivation by itself.

The unconditioned stimulus would be the biscuit itself, and salivation to the food would be the unconditioned response. Since the response here is to the rattle, the first option is correct.
