Exam 4 Flashcards
Define Extinction-
Discontinuation of an Already Existing reinforcement for a given behavior, leading to a decrease in its frequency.
In order for the process to qualify as Extinction-
- The process must Break the Response-Reinforcer Contingency
- The behavior you’re putting on extinction must have been previously reinforced.
- Behavior no longer results in reinforcement & stops occurring in the future.
- The procedure must Actually Withhold the functioning Reinforcer.
If the bx is maintained by…
SR+?
SR-?
Automatic SR?
+SR: No longer deliver positive reinforcement
-SR: No longer terminate the ongoing event (-SR)
Auto: Modify source of stimulation so behavior no longer produces it.
Factors determining Speed of Extinction Process?
- Reinforcement history
- Response Effort
- Correlated Stimuli
- Alternate Sources of Reinforcement
Explain how Reinforcement History impacts the Speed of the Extinction Process-
The behavior will extinguish faster if:
- It has been Continuously reinforced
- It has been maintained by a Smaller Magnitude of Reinforcement
- It has been reinforced under Highly Specific Conditions
Explain how Response Effort impacts the Speed of the Extinction Process-
The behavior will extinguish faster if:
- It requires More Effort to complete (exercise)
Explain how Correlated Stimuli impacts the Speed of the Extinction Process-
The behavior will extinguish faster if:
- Discriminative stimuli are eliminated.
Explain how Alternate Sources of Reinforcement impacts the Speed of the Extinction Process-
The behavior will extinguish faster if:
- Another Response is available to receive Sr+
What are some Cautions in performing Extinction?
- Dangerous behaviors
- If you Give Up after an extinction burst, you may worsen the behavior
- There may be Multiple Reinforcers maintaining the bx.
- Spontaneous Recovery
Increases in other responses as a result of extinction?
Aggression
- Emotional Responding
- Previously Reinforced Behaviors (resurgence)
- Increased Variability
Strategies for Implementing Extinction?
- Plan to start under conditions in which a burst can be tolerated.
- Be Consistent
- Combine with Reinforcement and Prompting Strategies
Explain Shaping-
- A procedure in which one reinforces Successive Approximations toward a tx.
- Useful when you have to teach a Single behavior
- Involves the use of Differential Reinforcement
In Shaping, does the individual already have the behavior in their repertoire?
Nope. Not in the slightest.
Steps of Shaping-
- Define the Target Behavior.
- Identify the first bx to reinforce
- Identify bx to put on extinction
- Differentially Reinforce Approximations
Limitations of Shaping?
- Requires Skillful training: Attention to Detail, Experience judging approximations (Flexibility)
- Progress is not always Smooth or Predictable
- May unintentionally reinforce alternate or Harmful Behaviors
