Study Notes
Behavior Chain
- Sequence of interrelated behaviors where each behavior cues the next.
- The final behavior leads to a reinforcer.
- Requires a specific order; the first antecedent is typically a motivating operation (MO).
Temporal Continuity
- Refers to behaviors being linked in a specific order over a short time frame.
Chaining
- Involves reinforcing successive components of a behavior chain.
- Each step acts as a cue for the next step, often relying on automatic reinforcement.
Forward Chaining
- Training starts with the first element of the chain, progressing sequentially.
- Must master each step before advancing to the next; this includes practicing the entire sequence gradually.
- Consistency in teaching method is essential.
Research Example
- Objective: Enable a person with severe disabilities to walk to school.
- Method: Used backward chaining and operant conditioning principles.
- Process: Started practicing near the school, praised for successes over three trials, gradually increased distance.
- Resulted in independent walking to school after 10 days and 17 sessions.
Rules
- Clearly define the target behavior; understanding the end goal is essential.
- Identify all necessary sequential steps for the behavior chain.
- Observe existing methods utilized by caregivers and the client’s current abilities.
- Adjust instruction based on client capabilities, potentially breaking tasks into smaller segments.
Reinforcing Successive Approximations
- Once steps are identified, reinforcement is necessary to encourage each step in order.
- Initial behavior may require shaping to emerge.
- Automatic reinforcement can be enhanced by adding external reinforcement methods.
Monitor Results
- Avoid reinforcing incorrect behavior; practice the chain in a uniform manner.
- Leverage existing skills of the individual to promote effectiveness.
- It may be beneficial to teach specific behaviors before integrating them into the overall chain, such as teaching how to zip before a dressing sequence.
Chaining vs. Shaping Similarity
- Both approaches aim to establish a target behavior that is not currently occurring.
Chaining vs. Shaping Difference
- Shaping progresses continuously with each new approximation being reinforced.
- In chaining, reinforcement usually occurs only at the end of the behavior chain.
- Backward chaining is a specific technique where training starts with the final step and works backward.
Backward Chaining
- Begins training with the last element of the chain and moves toward the first step.
- Closer temporal reinforcement for the last step enhances effectiveness, despite potential training difficulties.
