Behavior Change Procedures Flashcards
Created by David Premack, 1959
- A principle that states that making the opportunity to engage in High-probability behavior (something you are more likely to do) contingent upon the occurrence of Low-probability behavior (something you are less likely to do) will function as a reinforcer for the low-probability behavior.
AKA: Grandma’s Law; Relativity Theory of Reinforcement
-Usually stated as, “first_____, then_____.”
Premack Principle
Created by Timberlake and Allison, 1974
-Built on the Premack Principle
-A model for predicting whether contingent access to one behavior will function as reinforcement for engaging in another behavior based on whether access to the contingent behavior represents a restriction of the activity compared to baseline.
Restricting access to the behavior creates deprivation that serves as an EO, which makes the restricted behavior a very strong form of reinforcement.
Response Deprivation Hypothesis (RDH)
- Formal Similarity
- Model
- Immediacy
- Controlled Relation
Four Behavior-Environment Relations that Functionally Define: _____________
Imitation
The stimulus that is presented in an effort to evoke the imitative behavior. Any physical movement may function as a _________ for imitation.
\_\_\_\_\_\_\_\_ = Stimulus Imitation = Behavior ( of imitating the \_\_\_\_\_\_ stimulus)
Model
The model and the behavior must physically look alike and be in the same sense mode.
Formal Similarity
An imitative behavior must immediately follow the model within a few seconds.
- __________ IS CRITICAL, or it not considered to be imitation.
Immediacy
The model must be the controlling variable for the imitative behavior. The model must serve as the Sd for the imitative behavior.
- Best evidenced when the model is novel and still evokes an imitation. Sometimes called, Generalized Imitation.
Controlled Relation
Pre-arranged antecedent stimuli that help learners acquire new skills.
Ex. Video modeling
Planned Models
Unplanned models
Occur in everyday social interactions.
Ex. Watching people out in public and copying the behavior; copying a behavior from a movie
2 Types of Models:
- Planned Model
2. Unplanned Model
The goal is to teach individuals to “ do what the model does”.
Imitation Training
A behavior change produced by differential reinforcement.
- Reinforced members of the current response class occur with greater frequency and unreinforced members occur less frequently (because they are on extinction)
Overall result = A new response class.
Response Differentiation
Five (5) Steps of Imitation Training (Developed by Striefel):
- Assess and teach prerequisite skills for imitation training
- Select models for training
- Pretest
- Sequence models for training
- Implement imitation training
- Attending skills (e.g., staying seated, keeping hands in lap, etc.)
- Gross and fine motor skills required for tasks.
- If challenging behaviors interfere with teaching, they may need to be reduced or eliminated first.
Assess and teach any prerequisite skills for imitation training
Choose about 25 behaviors as models (including gross and fine motor, movement of body parts, and manipulation of objects).
Present 1 model at a time; present complex sequences later.
Selects models for training
Pretest
Assesses the individual’s ability to imitate any models already.
Sequence models for training
Using the pretest results, models are arranged from easiest to most difficult.
Pre-Assessment:
-Assesses the individual’s current performance level and determines progress in learning to respond to a model.
Training:
-The teacher repeatedly presents the models used in pre-assessment.
Post-Assessment:
-Assesses how well the individual performs previously and recently learned behaviors.
Probes for Imitative Behavior:
-Assess if the individual is developing an imitative repertoire.
Implement Imitation Training
- Keep training sessions active, short (10-15 minutes, a couple times a day).
- Reinforce both prompted and imitative responses.
- Pair verbal praise and attention with tangible reinforcers.
- If progress breaks down, back up and move ahead slowly.
- Fade out prompts.
Guidelines for Imitation Training
Teaches novel behavior.
Clicker training is an application of: ___________.
Shaping
A process involving systematically and differentially reinforcing successive approximations to a terminal behavior.
Shaping
The sequence of new response classes that emerge during the shaping process as a result of differential reinforcement. Each successive approximation is closer in form to the terminal behavior than the response class it replaces.
Successive Approximations
Reinforcing those responses within a response class that meet a specific criterion along some dimension (e.g., frequency, magnitude, etc.) and placing all other responses in the class on extinction.
Differential Reinforcement
Two (2) types of Shaping: AW
- Shaping ACROSS Response Topographies
2. Shaping WITHIN Response Topographies
Topography (form) of behavior remains constant.
Another measurable dimension of behavior is changed (e.g., duration of the behavior).
Shaping Within Response Topographies
Topography of the behavior changes during shaping.
Behaviors are still members of the same response class.
Shaping ACROSS Response Topographies
Both Change Behavior Gradually:
- _________ by changing response requirements.
- _________ by changing antecedent stimuli.
Shaping
Fading
- ) Assess Terminal Behavior and Available Resources
- ) Select the Terminal Behavior
- ) Determine Criterion for Success (Specify accuracy, speed, duration, magnitude, etc. of the terminal behavior).
- ) Analyze the Response Class (Identify the approximations that might be emitted during shaping).
- ) Identify the First Behavior to Reinforce (Some degree of the behavior should already be occurring in the individual’s repertoire; the behavior chosen should be a member of the targeted response class).
- ) Eliminate Interfering and Extraneous Stimuli
- ) Proceed in Gradual Stages
- ) Limit the Number of Approximations at each Level (If too many trials occur at a certain approximation, the behavior may become too firmly established).
- ) Continue Reinforcement when the Terminal Behavior is Achieved
Guidelines for Shaping
A specific sequence of discrete responses, each associated with a particular stimulus condition, where each response and the associated stimulus condition serve as an individual component of the chain.
Behavior Chain
When the components of an behavior chain are linked together, they produce a: ________ _________.
Terminal Outcome
Each Response in a Behavior Chain produces a stimulus change that simultaneously serves 2 functions:
- A conditioned reinforcer for the response that produced it and
- An Sd for the next response in the chain.
The first and last response of a behavior chain serves as either an:
Sd or Conditioned Reinforcer
- ) Performance of a specific set of discrete responses (each response has a clear beginning and an end)
- ) The performance of each response changes the environment in such a way that it produces conditioned reinforcement for the preceding response and an Sd for the next response.
- The response in the chain must be completed in the correct order, usually close to time.
Three (3) Important Characteristics of a Behavior Chain
The chain must be performed correctly and within a certain time.
Accuracy and rate are essential dimensions to limited holds.
Behavior Chain With A Limited Hold (LH)
- _________ __________ is a specific sequence of behaviors that lead to reinforcement.
- ___________ are various methods for linking specific sequences of stimuli and responses to form new performances.
Behavior Chain VS Chaining
- Increases independent living skills so that individuals can function more independently in society.
- Increases an individual’s current behavioral repertoire.
- Can be combined with other strategies in a treatment package to teach complicated repertoires.
Benefits of Chaining
- Required to implement the chaining procedures.
- Breaking complex skills into smaller, teachable units, the product of which is a series of sequentially ordered steps.
- Individualized to the person according to age, skill, level, disability, and prior experience.
Task Analysis
Chaining Steps:
- Create and Confirm the Task Analysis
- Assess Baseline Level of Mastered Steps
- Decide on Behavior Chaining Methods
Mastery is assessed to determine which components of the task analysis a person can perform independently.
- Two (2) Methods
1. Single Opportunity Method
2. Multiple Opportunity Method
Assess Baseline Level of Mastered Steps
To determine the sequence of behaviors that are necessary and sufficient to complete a given task efficiently.
- Three (3) Methods:
1. Observe a component individual perform the task.
2. Consult with experts or persons skilled in performing the task.
3. Perform the task yourself.
Create and Confirm The Task Analysis
Assesses an individual’s ability to perform each behavior in the task analysis in correct sequence. A (+) or (-) is scored for each correct or incorrect behavior emitted. Once the individual scores a minus, all subsequent steps are also scored (-) and the assessment immediately stops.
Single Opportunity Method
Evaluates the individual’s baseline level of mastery across all behaviors in the task analysis. If a step is performed incorrectly, out of sequence, or the time limit for the step is exceeded, the behavior analyst completes that step for the individual and then prompts the learner to do the next step.
WARNING: The teacher should not help the individual with any of the steps.
Multiple Opportunity Method
- More conservative of the 2 methods.
- Provides less information to the teacher once instruction is initiated.
- Quicker to conduct
- Reduces likelihood of learning taking place during assessment.
Single Opportunity Method
- Each step performed correctly is scored as correct, even if the learner erred on the previous steps. Total correct responses are scored even though out of sequence.
- Takes more time to complete.
- Provides information about steps the individual has mastered or with what exactly he/she needs additional help.
- Increases the likelihood of learning taking place during the assessment.
Multiple Opportunity Method
Four (4) Behavior Chaining Methods: FB BLAT
- Forward
- Backward
- Backward With Leap Aheads
- Total Task
- Behaviors identified in the task analysis are taught in their naturally occurring order.
- Training the 1st link first, the 2nd link second, the 3rd link third, etc. and joining all trained links together.
- The individual will not proceed to step 2 until the 1st step is mastered; once the first step is mastered, the learner will be required to complete step 1 & 2 to earn reinforcement.
- This continues until all steps in the task analysis are completed by the individual correctly.
Forward Chaining
AKA: Total-Task Presentation; Whole-Task Method; Concurrent Chaining
- A procedure in which EVERY STEP in the task analysis is taught to the individual during EVERY SESSION.
- Is considered a variation of forward chaining
- Each step the individual is unable to perform independently is trained until he/she is able to perform all the responses in the correct order. If necessary, graduated guidance or physical prompting is used.
Total-Task Chaining
- It can be used to link smaller chains to larger ones.
- It is relatively easy, so teachers are likely to use it in the classroom.
Forward Chaining
- A procedure in which the trainer completes all the initial steps except for the last step, at which point:
1. The individual is taught to complete the last step, and
2. Once the individual has mastered the last step, then he/she is required to complete the last two steps in order to receive reinforcement. - This continues until the learner is able to complete all the steps in the task analysis.
- The first behavior the individual performs independently produces the terminal reinforcement.
Backward Chaining
- Same protocol as the backward chain, but not every step in the task analysis is trained.
- Some steps are simply probed.
- If the step is already in the individual’s behavioral repertoire, it does not need to be trained and you can simply LEAP AHEAD over that step.
Backward Chaining With Leap Aheads
Advantage
- On each trial, the individual comes into contact with the terminal reinforcer for the chain.
Disadvantage
- The potential passive participation of the individual in earlier steps.
- Can slow down the learning process especially if the individual has mastered some of the steps in the chain.
Advantages and Disadvantages of Backward Chaining
Purpose of this is to decrease total training time needed to learn the chain.
Backward Chaining With Leap Aheads
AKA: Unchaining; Disrupting a Chain; Unlinking a Chain
-A method designed to lesson behavior by unlinking one element of the chain from the next so that one link no longer serves as a discriminative stimulus for the next link, nor as a conditioned reinforcer for the prior link.
- Unchaining can occur with desirable and undesirable behaviors.
- Inappropriate chains can be broken by determining the initial Sd and substituting another Sd for an alternate behavior or by extending the chain and building in time delays.
Interrupting and Breaking Behavior Chains
- Relies on an individual’s ability to perform the critical steps of the chain independently, but the chain is interrupted at a predetermined step so that another behavior can be emitted.
- Effective strategy for increasing speech and language abilities.
Behavior Chain Interruption Strategy (BCIS)
Steps to Breaking An Inappropriate Chain:
- Reexamine the Sd and the response
- Determine whether similar Sds cue different responses
- Analyze the natural setting to identify relevant and irrelevant Sds
- Determine whether Sds in the natural setting differ from training Sds.
- Identify the presence of novel stimuli in the setting
Factors Affecting the Performance of A Behavior Chain
- ) Completeness of the task analysis
- ) Length or complexity of the chain
- ) Schedule of Reinforcement
- ) Stimulus Variation
- ) Response Variation
-An extremely popular and effective strategy.
Involves 2 parts:
- Reinforcement contingent on:
- The occurrence of a behavior other than the challenging behavior.
- Challenging behavior occurring at a reduced rate. - Withholding Reinforcement (extinction) for the challenging behavior as much as possible
Differential Reinforcement
Six (6) Types of Differential Reinforcement: (HI LOAD)
- Differential Reinforcement of High Rates of Responding (DRH)
- Differential Reinforcement of Incompatible Behavior (DRI)
- Differential Reinforcement of Low Rates of Responding (DRL)
- Differential Reinforcement of Other Behavior (DRO)
- Differential Reinforcement of Alternative Behavior (DRA)
- Differential Reinforcement of Diminishing Rates of Responding (DRD)
- A procedure in which behavior cannot be emitted simultaneously with the challenging behavior (incompatible).
- The behavior being differentially reinforced and behavior on extinction are mutually exclusive response class.
- Technically, ______ is a sub-type of DRA.
DRI
AKA: Alt-R
- A procedure in which one reinforces the occurrence of behavior that provides a desirable alternative to the problem behavior; not necessarily behavior incompatible with it.
- Alternative behavior and challenging behavior are NOT incompatible.
- Alternative behavior and challenging behavior are part of the same response class, meaning that the alternative behavior will result in the same consequence as the challenging behavior and thus will compete successfully because it makes the challenging behavior ineffective.
DRA
DRA & DRI are very similar. They both share:
A dual effect of weakening problem behavior and simultaneously strengthening acceptable behavior.
Differential NEGATIVE Reinforcement of Incompatible/Alternative Behavior (DNRI/DNRA)
Terms that are sometimes used to refer to differential reinforcement procedures that specifically involve escape as the reinforcer.
- ) Select Incompatible/Alternative Behavior: (Already in individual’s repertoire; requires equal or less effort than the challenging behavior; is being emitted at a frequency that will provide sufficient opportunities for reinforcement before intervention; Likely to be maintained in the individual’s natural environment over time).
- ) Select Reinforcers that are Powerful and can be Delivered Consistently: (The magnitude of reinforcement is less important than its consistent delivery and control).
- ) Reinforce Incompatible/Alternative Behavior Immediately and Consistently
- ) Withhold Reinforcement for the Challenging Behavior
- ) Combine DRI/DRA With Other Procedures: (Combine with response blocking, time-out etc. to produce a more potent intervention for behaviors that are destructive, dangerous, etc.)
Guidelines for Using DRI/DRA
AKA: Differential Reinforcement of zero Responding; Omission Training
- A procedure in which reinforcement is contingent on the absence (omission) of the challenging behavior.
- Reinforcers are received when challenging behavior has NOT been displayed during or at certain certain time periods.
- Delivery of reinforcement is determined by how the omission requirement is implemented and scheduled.
DRO
Four (4) Sub-Types of DRO
- Fixed-Interval DRO (FI-DRO)
- Variable-Interval DRO (VI-DRO)
- Fixed Momentary DRO (FM-DRO)
- Variable Momentary DRO (VM-DRO)
