Topic 24 Reinforcers

Behavior and Reinforcement
- Behavior is learned or maintained by the consequences it produces in the environment.
- Every behavior is followed by a stimulus change immediately afterward, termed the consequence.
- If the consequence is beneficial, the behavior is more likely to remain or increase in frequency.
Reinforcement
- Defined as the process that strengthens or increases the likelihood of a behavior occurring again in the future based on a beneficial consequence.
- Successful reinforcement requires observing an increase in behavior post-consequence.

Classification of Reinforcers
- There are two main types of reinforcers:
- Conditioned Reinforcers
  - Requires a learning history involving interaction with the consequence to understand its benefits.
  - Examples include:
  - Money
  - Tokens
  - Toys
  - Trophies
  - Stickers
  - Certificates
  - Words of praise
  - Importance of learned associations with specific stimuli.
- Unconditioned Reinforcers
  - Do not require prior experience to recognize their benefits.
  - Universally desired items, such as:
  - Food
  - Water
  - Sleep
  - More complex unconditioned reinforcers can include:
  - Tactile sensations (pleasant touches)
  - Certain food smells or sweet scents
  - Relief from discomfort (heat, cold, or pain).
  - Individual differences in preferences exist, but basic sensory preferences are inherent to all individuals.

Role of RBT (Registered Behavior Technician)
- Responsible for delivering conditioned or unconditioned reinforcers to clients.
- Some clients may need unconditioned reinforcers (like food/drink) in their therapy programs.
- Can be incorporated naturally during activities (e.g., cooking and eating a meal).
- Alternatively, contrived situations can be used (e.g., earning goldfish crackers for task completion).
Transition from Unconditioned to Conditioned Reinforcers
- Important to fade unconditioned reinforcers over time.
- Short-term usage of unconditioned reinforcers might be necessary when clients lack a history with conditioned reinforcers.
- Example:
- Typically developing children find adult praise reinforcing, necessitating a history of learning.
- For clients with less learning history, pairing unconditioned (e.g., edible) with conditioned reinforcers (e.g., verbal praise) is vital.
- Process for pairing includes:
- Start by providing verbal praise immediately followed by a small piece of food (e.g., cracker).
- Gradually reduce the frequency of food reward while consistently offering praise until only praise is provided.
Long-Term Goal
- Aim for naturally occurring reinforcement:
- Gradually phase out unconditioned reinforcers, replacing them with conditioned reinforcers.
- Eventually shift to a natural schedule of reinforcement.

Concerns about Reinforcement vs. Bribing
- Reinforcement is fundamentally different from bribery.
- Reinforcement aims to enhance behaviors or skills beneficial to the learner.
- Bribery is self-serving, intending to coerce someone into illegal or unethical actions.
- Reinforcement is a natural part of daily life for all individuals and should be approached as a tool for positive growth.
