In psychology, reinforcement is a key concept in behavior modification. B.F. Skinner demonstrated this with his experiments involving rats in what is known as a Skinner box. The rats learned to press a lever to receive food, a primary reinforcer that fulfilled their innate need for nourishment.
Effective reinforcers for humans vary depending on the individual and the context. Primary reinforcers, such as food, water, sleep, shelter, and pleasure, have inherent value and satisfy basic biological needs. For instance, promising a toy to a child for cleaning their room or giving candy to a soccer player for scoring a goal are examples of using primary reinforcers.
In contrast, secondary reinforcers derive their value through association with primary reinforcers. Praise, money, and stickers are common secondary reinforcers. Praise, such as appreciation for good grades, is valuable because it is associated with affection and social approval. Money is useful because it can be exchanged for primary reinforcers like food or secondary reinforcers like entertainment. Stickers, often used in behavior charts, gain value when they can be traded for rewards.
Token economies utilize secondary reinforcers in structured behavior management systems. Tokens, like poker chips or stars, are awarded for desired behaviors and can later be exchanged for rewards. This system is effective in various settings, including schools, prisons, and mental health facilities. For example, studies have shown that token economies can improve social behaviors and academic performance. In one study, children earned tokens for not exhibiting aggressive behaviors and could exchange these tokens for playtime.
Reinforcement can be achieved through primary reinforcers, which fulfill basic needs, and secondary reinforcers, which acquire value through association with primary reinforcers. Token economies leverage secondary reinforcers to modify behavior across diverse environments effectively.
Primary reinforcers have innate reinforcing qualities that are not learned.
For humans, primary reinforcers include food, sleep, affection, and shelter, which inherently satisfy basic needs.
Likewise, secondary reinforcers, such as praise and money, have no inherent value and only gain reinforcing qualities when linked with a primary reinforcer.
Secondary reinforcers acquire their positive value through experience and are learned or conditioned reinforcers. For instance, praise becomes reinforcing because it is associated with affection.
Similarly, money, another secondary reinforcer, is useful when buying primary reinforcers like food or secondary ones like entertainment.
Likewise, token economies use secondary reinforcers in structured systems such as schools and mental health facilities.
For example, students earn tokens for good behavior and trade them for a no-homework pass, making token economies effective in schools.
In addition, patients in mental health facilities earn tokens like coins for attending therapy sessions, which they can trade for additional recreational activities.
