Dr. peterson teaches a lab course on applied behavior modification in which students teach chickens. the student's first assignment involves observing the chicken's behavior. after a hungry chicken exhibits a target behavior, its student makes a click with a clicker and follows the click with food. soon the chickens associate the clicker with food and will repeat any behavior followed by a click. the click sound now serves as:
select one:
a. a primary reinforcer
b. an conditioned response
c. a secondary reinforcer
d. a discriminative stimulus

c. a secondary reinforcer

Explanation:

Secondary Reinforcement a behaviour is reinforced by a stimulus which is related to a previous primary reinforcer or stimulus that is based on our survival instinct.

Secondary reinforcer is meant to either assist us or do the opposite of that such as clicking for a chicken at first the chicken hears this and see that you doing it to give them food now when they hear clicking they associate it with food so clicking becomes a secondary reinforcer associated with primary reinforcer.

Clicking doesn't directly fulfill your hunger but it's a means to get the food hence it's secondary reinforcer.
