Final answer:
A secondary reinforcer is a stimulus or event that gains reinforcing qualities when linked with a primary reinforcer. Examples include praise and money. Secondary reinforcers are important in behavior analysis and can be used in behavior modification programs like sticker charts.
Step-by-step explanation:
A secondary reinforcer is a stimulus or event that has no inherent value but gains reinforcing qualities when linked with a primary reinforcer. For example, praise can serve as a secondary reinforcer when linked with primary reinforcers like affection. Similarly, money is a secondary reinforcer because its value lies in its ability to be used to obtain primary reinforcers or other secondary reinforcers.
In the context of behavior analysis, secondary reinforcers play a crucial role in shaping and maintaining behavior. They are often used in behavior modification programs, such as sticker charts where stickers serve as secondary reinforcers. These charts rely on the association of the stickers with the primary reinforcer of praise or rewards.
