Miranda notices that her cat salivates as soon as her cat hears the sound of the electric can opener. In this example, the sound of the can opener is the .a. primary stimulus. b. positive reinforcer. c. conditioned stimulus. d. secondary reinforcer. e. tertiary reinforcer.

Option C, conditioned stimulus

Explanation:

A conditioned stimulus is a neutral stimulus which can be associated with a unconditioned stimulus to produce a conditioned response. In case of Miranda, opening sound of can serves as a conditioned stimuli, memories associated with food item’s taste and smell is an unconditioned stimuli and salvation is a conditioned response which occurs when the cat hear  sound of can opening. Salvation is termed as conditioned response because salvation tends to be the response associated with food (unconditioned stimuli) and not with a sound (conditioned stimuli)
