Differential Reinforcement Study Notes

Differential Reinforcement Overview

  • Differential reinforcement is a behavioral technique used to reinforce desired behaviors while withholding reinforcement for undesired behaviors.

Key Concepts

  • Reinforce behaviors that are functional or socially appropriate, such as asking for a break, while withholding reinforcement for problematic behaviors like screaming.
  • The goal is to increase the appropriate behavior and decrease the concerning behavior.

Types of Differential Reinforcement

  • Different types of differential reinforcement strategies can be implemented based on the desired outcomes.

Reinforcement of Alternative Behavior (DRA)

  • Definition: Reinforcing a specific behavior (alternative or replacement skill) while withholding reinforcement for the undesired behavior.
  • Example: If a student screams for attention, reinforcing them when they ask for a break instead of screaming.

Reinforcement of Other Behavior (DRO)

  • Definition: Reinforcing any behavior that is not the problem behavior, often referred to as zero behavior in some texts.
  • Example: A student is rewarded (e.g., a movie treat) for not using their phone during an online class, but this does not teach productive behavior.
  • Implications: This method may not be effective long-term as it doesn't teach the individual what they should do instead, just what not to do.

Reinforcement of Incompatible Behavior (DRI)

  • Definition: Reinforcing a behavior that cannot occur simultaneously with the undesired behavior.
  • Example: A coach reinforces a runner by giving them a break only when they are running; they do not get a break while walking.
  • Challenges: While behaviors may seem incompatible, they may not serve the same function, complicating the effectiveness of DRI.

Differential Reinforcement of Low Rates (DRL)

  • Definition: This approach involves reinforcing behaviors that occur infrequently, aiming to reduce the frequency without eliminating the behavior entirely.
  • Example: A student who typically raises their hand 20 times during a lesson might be reinforced for reducing that to 5 times.
  • Purpose: Allow continued behavior but at reduced frequency.

Differential Reinforcement of High Rates (DRH)

  • Definition: This method focuses on reinforcing high rates of a desired behavior when the learner shows the ability but is currently not engaging enough in that behavior.
  • Example: A teacher reinforces less frequent classroom participation by rewarding a student who raises their hand more often throughout the day.

Implementation Strategies

  • Positive Reinforcement: Adding a pleasurable stimulus (e.g., giving a banana for saying the word correctly).
  • Negative Reinforcement: Removing an unpleasant stimulus (e.g., no homework for well-behaved class).

Schedules of Reinforcement

  • Continual reinforcement is used initially to teach new skills, while fading into intermittent reinforcement is used for sustained improvement.
  • The initial reinforcement should be consistent to encourage engagement with the new behavior.

Ethical and Practical Implications

  • Using differential reinforcement without teaching replacement behaviors can lead to alternative problematic behaviors developing as individuals seek the reinforcement they desire.
  • Long-term reinforcement strategies should always aim for skill development rather than just behavior suppression.

Special Considerations

  • Distinguishing between reinforcement strategies like DRA and DRO can guide educators in addressing classroom disruptions effectively.
  • Behavior functions must be analyzed to implement suitable reinforcement strategies effectively and ethically.
    • Tangible Reinforcement: Students often seek tangible items or activities, highlighting the importance of identifying the function behind disruptive behaviors.

Conclusion

  • Understanding and implementing various types of differential reinforcement can lead to meaningful change in behavior and skill acquisition. It is essential to focus not only on eliminating undesirable behaviors but also on teaching and reinforcing appropriate, functional behaviors.

Upcoming Assignments

  • Students are reminded about upcoming quizzes on functions of behavior and schedules of reinforcement, due on specific dates. Discussion topics regarding extinction will be covered in future classes, with a focus on its complexities and potential consequences.
