section 8 Flashcards
Prepackaged principle
Aka
Grandmas law
Theory of reinforcement
Response deprivation hypothesis
Created by Timberlake and Allison 1974
Built
On Premack principal
Restricting access to the behavior creates deprivation that serves as an EO which makes the restricted behavior a very strong form of reinforcement
4 behavior environment relations that functionally define imitation
Formal similarity
Model
Immediacy
Controlled relation
Formal
Similarity
The model and the behavior must physically look alike and be in the same sense mode
Model
The stimulus that is presented in an effort to evoke the imitative behavior
Immediacy
An imitative behavior must immediately follow the model within just a few seconds it is critical
Controlled relation
The model must be the controlling variable for the imitative behavior.
Two types of modes
Planned and unplanned models
Planned models
Pre-arranged antecedent stimulus that help learners acquire new skills
Example video models
Unplanned models
Occurs in every day social interactions
Five steps of imitation training
- Assess and teach any pre-requisite skills for imitation training
- Select models for training
- Pretest
- Sequence models for training
- Implement imitation training
Shaping
A process involving systematically and differential lay reinforcing successive approximations to a terminal behavior
Shaping teaches novel behaviors
Differential reinforcement
Reinforcing those responses within a response class that meet a specific criterion along some dimension (frequency, magnitude, etc…) and placing all other responses in the class on extinction
Successive approximations
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 that the response class it replaces
Response differentiation
A behavior change produce for differential reinforcement
Overall result = a new response class
Reinforced members of the current response class occur with greater frequency and unreinforced members occur less frequently because they are on extinction
Two types of shipping methods
AW
Across
Within
Shaping across
Shaping across response topographies
Topography of behavior changes during shaping
Behaviors are still members of the same response class
Shaping within
Shaping within response topographies
Topography of behavior remains constant
Example duration of time spent practicing piano increases via shaping
Shaping versus fading
Both change behaviors gradually
Shaping by changing response requirements
Fading by changing antecedent stimuli
Guidelines for shaping
Assess the terminal behavior abs avaiable resources
Select the terminal behavior
Determine criterion for success
Analyze the response class
Id the first behavior to reinforce
Eliminate interfering abs extraneous stimuli
Proceed in gradual stages
Limit the number of approximations at each level
Continue reinforcement when the terminal behavior is achieved
Behavior chain
A specific sequence of discreet responses each associated with a particular stimulus condition where each response and the associated stimulus condition serve as an individual components of the chain
Three important characteristics of a behavior chain
Performance of a specific set of discrete responses
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 in time
Behavior train with limited hold
The chain must be perform correctly and within a certain time
Example when dialing the phone number on a traditional phone if you did not dial the number within a certain timeframe the phone would go to the busy signal
Behavior chain versus chaining
Behavior chain is a specific sequence of behaviors that lead to reinforcement
Chaining is various methods of linking specific sequences of stimuli and responses to form a new performance
Task analysis
Breaking down complex skills into smaller teachable units
Chaining steps
Create and confirm the task analysis
Assess baseline level of mastered steps
Decide on behavior chaining methods
Single opportunity method for chaining
Access is an individual’s ability to perform each behavior in the task analysis in the correct sequence
Multiple opportunity method for chaining
Evaluates individuals baseline level of mastery across all behaviors in the task analysis
If I step is performed incorrectly out of sequence or the time limit for the staff has exceeded the behavior analyst completes that step for the individual and then prompts to learner to do the next step
4 behavior training methods
FB BLAT
Forward
Backward
Backward with leaps ahead
Total task
Forward chaining
Behaviors identified in the task analysis are taught in their naturally occurring order
Total task 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
Technically, it is considered a variation of forward chaining
Backward chaining
A procedure in which the trainer completes all the initial steps except for the last step at which the individual is taught the last step
Once the get the last step, they then do the last two steps etc…
Backward chaining with Leap a heads
Same protocol
As the backward chain but not every step in the task analysis is trained.
Some
Steps are simply probed.
Interrupting and breaking behavior chains
Aka
Unchaining
Disrupting a chain
Unlinking a chain
Method designed to unlink one element of the chain so that the next link doesn’t serve as discriminative stimulus for the next link-
So we know how to make a cake - we start that chain but then switch over the making muffins- some similar links but now we add more to the chain
Breaking an inappropriate chain
Re-examine the Sd and the response
Determine whether similar Sd’s cue different response
Analyze the natural setting to id relevant and irrelevant Sds
Determine whether Sds in the natural setting differ from training Sds
Id the presence of novel stimuli in the setting
Factors affecting the performance of behavior chain
Completeness of the task analysis
Length or complexity of the chain
Schedule of reinforcement
Stimulus variation
Response variation
Differential reinforcement
Reinforcement contingent on the occurrence of a behavior other than the challenging behavior and challenging behavior occurs at a reduced rate
Withhold reinforcement for the challenging behavior as much as possible
Six types of differential reinforcement
HI LOAD
DRH- Turn she’ll reinforcement of high rates of responding
DRI- Differential reinforcement of incompatible behavior
DRL- Differential reinforcement of low rates of responding
DRO- Differential reinforcement of other behavior
DRA- Differential reinforcement of alternative behavior
DRD- Differential reinforcement of diminishing rates of responding
DRI
A procedure in which behavior cannot be omitted simultaneously with a challenging behavior or that it’s incompatible
Example an individual cannot refuse to eat food and eat food at the same time
Dual effect of weakening problem behavior and strengthening acceptable behavior
DRA
The procedure in which one reinforces the occurrence of behavior that provides a desirable alternative to the problem behavior but not necessarily behavior that’s incompatible with it
Dual effect of weakening problem behavior and strengthening acceptable behavior
Example coworkers are bickering so employer gives them an assignment to work as a team the bickering decreases as they work on the assignment
