Section G Flashcards
Premack Principle
- A strategy that uses behavior as SR
- Hi-P request sequence
AKA: Relativity Theory of SR; Grandma’s Law
Premack Principle AKAs
- Relativity Theory of SR
- Grandma’s Law
Response Deprivation Hypothesis (RDH)
Takes Premack to the next level
- Restricts the behavior to create an EO, making the behavior a powerful SR
Antecedent Interventions
- Implemented prior to and NOT contingent on behavior
AKA: Antecedent Procedures; Antecedent Control; Antecedent Manipulation
Antecedent Intervention AKAs
- Antecedent Procedure
- Antecedent Control
- Antecedent Manipulation
Antecedent Intervention (Methods)
- Manipulating MOs
- Decreasing required response effort
- Teaching alternative behaviors
- Using differential consequences
- Limiting opportunities to emit the challenging behavior
- Increasing opportunities to emit the desired behavior
Types of Antecedent Interventions
- Contingency-Dependent
- Contingency-Independent
Contingency-Dependent Antecedent Interventions
- SDs (Stimulus Control)
- Differential consequences for correct/ alternative behaviors vs challenging behaviors
Contingency-Independent Antecedent Interventions
- Intervention bases on MOs
- Interventions that do not depend on consequences for target or alternative behaviors
- EO/AO manipulations create evocative and abative effect on behavior
3 Antecedent Interventions
- NCR
- High-P Instructional Sequence
- FCT
Noncontingent Reinforcement (NCR) (Definitions)
An Antecedent Intervention
- Clients are reinforced on a time-based schedule independent of the target behavior
- Reinforcers that maintain challenging behavior are delivered on a fixed or variable time schedule creating an AO for that behavior
- Must know the function to determine whether to use positive, negative, or automatic SR
NCR (Uses)
For decreasing challenging behavior proactively in a non-aversive manner
- NCR SR+ = Time-based access to attention or tangible
- NCR SR- = Time-based escape from demands
- NCR Auto = Time-based access to sensory feedback
NCR (Pros)
- Easy to implement because you don’t have to monitor all the time
- Creates a positive learning environment
- Can be used in treatment packages
- Unintended pairing of desired behavior and the NCR reinforcers may strengthen and maintain those desirable behaviors
– NCR + EXT - Effective for reducing EXT induced burst
– NCR+ DRO - Can decrease the chance that challenging behavior will contact SR
NCR (Cons)
- Decreased motivation to engage in appropriate behavior because of free access to NCR stimuli
- Unintended pairings of challenging behavior and the reinforcers may reinforce challenging behavior
- Doesn’t teach new behaviors
- Can be distracting in the instructional setting
What’s the difference between FT/VT and FI/VI?
FT/VT schedules are NCR
vs
FI/VI schedules are dependent on the passage of time AND the correct behavior
High-Probability Instructional Sequence
An Antecedent Intervention
- Used to increase compliance and reduce escape-maintained behaviors
- Has an abative effect on low probability / compliance behaviors due to SR being given to hi-p responses
- Has a differential SR effect: The low probability / compliance is placed on extinction and compliance is differentially reinforced
AKA: High-P; High-Probability Request Sequence; Interspersed Request; Pre-Task Requests; Behavioral Momentum
High-Probability Instructional Sequence AKAs
- High-P
- High-Probability Request Sequence
- Interspersed Request
- Pre-Task Requests
- Behavioral Momentum
Functional Communication Training (FCT)
An Antecedent Intervention
- Carr and Durand
- Trains clients to use communicative behavior to replace challenging behavior evoked by MOs
- DRA: Must be functionally equivalent to the challenging behavior
Conditioned Reinforcers Considerations
- They allow us flexibility to appeal to more than one client at a time
- Important to consider what natural SR will look like
- Must be assessed and used in every program that aims to increase desired behaviors or replace challenging behavior
Prompts
- Additional antecedent stimuli added to help evoke the correct response
- Used prior and during response
- Should be faded as quickly as possible
Prompt Dependence
Failure to transfer control of the behavior to the SD from the prompt
2 Types of Prompts
- Response Prompts
- Stimulus Prompts
Response Prompts
- Operate on the client’s behavior to hint towards the correct response
- Do not change the task or stimuli
3 Types: Verbal, Model, Physical
Verbal Instructions
Response Prompt
- Vocal and non-vocal (written, spoken, pictures, etc.)
- Useful in all learning contexts
Modeling
Response Prompt
- A demonstration of the correct behavior
- Effective for learners who can imitate
Physical Prompt
Response Prompt
- Trainer guides throughout the behavior
- Used with younger and severely disabled clients
Cons:
- Most intrusive
- Tough to fade
- Not all clients respond well to physical touch
Fading Response Prompts
Transfer stimulus control to from the prompt to the SD
4 Ways to Fade:
- Most to Least Prompting
- Least to Most Prompting
- Graduated Guidance
- Time Delay Prompting
Most to Least Prompting
- Steadily guide client through the entire response, systematically reducing the amount of physical assistance
- Typically goes from physical guidance to less intrusive prompts, such as visual guides, verbal instructions, and then the actual SD
Least to Most Prompting
Trainer allows client an opportunity to respond within set period of time independently, increasing prompts contingent on incorrect responding
