When a stimulus has no natural capacity for serving as a reinforcer, but acquires reinforcing properties as a function ofbeing paired with a primary reinforcer, we call that stimulus a or "conditioned reinforcer."

Secondary reinforcer

Explanation:

The secondary reinforcer can be explained or described as a situation whereby a stimulus is known to strengthen or support a behavior which has been initially associated with the primary reinforcer.

The secondary reinforcer is also known as a conditioned reinforcer, while the primary reinforcer is also known as the unconditioned reinforcer.

Some of the examples of secondary reinforcer include  money, grades in schools, and tokens, while that of primary reinforcer are food, drink, and pleasure.

In conclusion, the secondary reinforcer has acquired a reinforcing function through pairing with an unconditioned or primary reinforcer.
