Behavior Change Procedures Flashcards
Premack Principle
A principle statement to engage in high-probability behavior contingent upon the occurrence of low probability behavior will function as a reinforcer for the low probability behavior
First /then
Do this /then you can
Response Deprivation Hypothesis
Model 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
4 Behavior-Environment Relations That Functuonally Define Imitation
F MIC Formal Similarity Model Immediacy Controlled Relation
Formal Similarity
The model and the behavior must have formal similarity- must physically look alike
Model
Any physical movement may function as a model for imitation
Immediacy
An imitative behavior must immediately follow the model
CRITICAL
Controlled relation
Model must be the controlling variable for an imitative behavior
2 Types of Models
Planned- Prearranged
Unplanned- Everyday
5 Steps for Imitation Training
Assess and teach any pre-req before training Select models for training Pretest Sequence training Implement training
Shaping
A process involving systematically and differentially reinforcing successive approximation to a terminal behavior
Teaches novel behavior
Differential Reinforcement
Reinforcing those responses within a response class that meet a criterion and placing all other on extinction
Successive Reinforcement
Sequence of new response classes that emerge during the shaping process as a result of differential reinforcement
Each successive approx is closer to form behavior
Response Differentiation
A behavior change produced by differential reinforcement
2 Types of Shaping Methods
AW
Across Response Topographies
Within Response Topographies
Shaping Across Response Topographies
Topography of behavior changes during shaping
Still members of same response class
Shaping Within Response Topographies
Topography of behavior remains constant
Another measurable dimension of behavior is changed
Shaping Vs. Fading
Shaping by changing response requirements
Fading by changing antecedent stimuli
Guidelines For Shaping
Assess Terminal Bx and Resources Select the Terminal Bx Determine Criterion for Success Analyze the Response Class Identify First Bx to Reinforce Eliminate Interfering and Extraneous Stimuli Proceed in Gradual Stages Limit # of Approx. Continue Reinforcing When Bx is Achieved
Behavior Chain
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
When the components are linked together they produce outcome
Conditioned reinforcer >SD>Response
3 Important Characteristics of a Bx Chain
Performance of a specific set of discrete responses
Performance of each response changes the environment in such a way that it produces conditioned reinforcement for preceding response of an SD for the next response
Response in the chain must be completed in the correct order usually close in time
Behavior Chain With a Limited Hold
The chain must be performed correctly and within a certain time
Accuracy and rate are essential dimensions to limited holds
Behavior Chaining Vs. Chaining
Bx Chain- specific sequence of Bx that lead to reinforcement
Chaining- Various methods for linking specific sequences of stimuli and responses to form new performances
Benefits of Chaining
Increases independent living skills so that individuals can function more independent in society
Elaborates an individual’s current behavioral rep.
Task Analysis
Required to implement the chaining procedure
Breaking skills into smaller steps
