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

Answer: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.
