Units 1-6 Flashcards
Type of work conducted in early behavior analysis
Topography based behavior modification/management
Populations served in early behavior analysis
Prisoners, severe autism, mental retardation, schizophrenia
Conducted the early applications of behavior analysis
Behavioral experimental psychology graduates
Used by ABA pioneers to evaluate effectiveness in the real world
Early applications of EAB
Year ABA was formalized
1968
Caused the drift to behavior modification and management
Institutional need for “behavior modifiers”
Approach used by behavior modifiers
“Topography based” behavior reduction
Focuses only on problem behavior
Behavior management
4 characteristics of behavior modification/management
- Cook-book approach
- Topography-based
- Technologist
- Procedures at the core
4 characteristics of behavior analysis
- Individualized
- Function-based
- Analysts
- Basic principles at the core
4 characteristics of problem behavior
- Minimizes achieving meaningful outcomes
- Minimizes access to reinforcers
- Maximizes contact with punishers
- May result in restricted access to community
5 parameters of problem behavior
- Rate (too high)
- IRT (too short)
- Duration (too long)
- Severity/intensity (too high)
- Wrong place, situation, or . time
Model for treating problem behavior based on form of the behavior
Topography-based treatment model
3 characteristics of topography-based treatment procedures
- Delivered aversive and restrictive punishers
- Used artificial and arbitrary reinforcers
- Used thinned reinforcement schedules
“One-size fits all” approach
Cook-book approach
Taught non-functional incompatible behavior
Topography-based DRI
Alternative behavior benefited caregivers and not client
Topography-based DRA
3 limitations of the topography-based treatment model
- Contingent relations not broken
- Behavior did not maintain or generalize
- Problem behavior hidden under tight stimulus control
Model for treating problem behavior based on the function
Function-based treatment model
An appropriate form of communication is taught to replace problem behavior
Functional Communication Training (FCT)
FCT-stage 1
Conduct a functional assessment or analysis
FCT-stage 2
Train and differentially reinforce communicative response
FCT-stage 3
Transfer control to real-life settings and persons
More specific words taught and results in a larger speaker repertoire
Mand training
3 strategies for promoting generalization in FCT
- Incorporate multiple trainers and settings
- Include all stimuli
- Sequential modification
Is our subject matter behavior alone?
No; includes operants, respondents, contingencies, functional relations
Are the “functions of behavior” only “attention, tangibles, escape and automatic reinforcement”?
No; typical statements about function are oversimplifications
Should antecedents have only a first name?
No; antecedents only exist in relation to consequences (last name)
Can we neglect context?
No; behavior changes in relation to context
Are we effective if we only change behavior?
No; change real-world contingencies to achieve meaningful outcomes
Manipulation of a stimulus produces a reliable and predictable change in a response
Functional relation
4 characteristics of functional relations
- Probabilisitic
- Nonlinear
- Complex
- Allows for predictions
Not cause and effect or deterministic
Functional relations are probabilistic
Compared to non-linear equations in calculus
Functional relations are non-linear
Functional relations change with respect to context
Functional relations are complex
What an organism “does” and “why’
Everyday usage of the term function
A mathematical relation between stimulus classes and response classes
Scientific usage of the term function
Problem with using the “everyday definition of function”
Practitioners use teleological explanations
One event depends on another
Contingency
Derive effects on behavior from a past history of differential availability with a consequence
Discriminative Stimuli
Derive effects on behavior from their value altering effect on consequences
Motivating operations
Consequence leads to the development of that discriminative stimulus
Last name of discriminative stimuli
The consequence whose value is being altered
Last name of motivating operations
2 or more simultaneous, but independent schedules for different responses
Concurrent Schedules
Distribution of bx on concurrent schedules of SR+ to predict response allocation
The matching law
4 other variables influencing response allocation (choice)
- Response effort
- Response quality
- Reinforcer delay
- Reinforcer magnitude/duration
Amount of effort to complete a response
Response effort
Time it takes to deliver a reinforcer
Reinforcer delay
Overall value of a reinforcer
Reinforcer quality
Amount of reinforcer provided
Reinforcer magnitude
Length of access to a reinforcer
Reinforcer duration
A previously reinforced behavior no longer produces reinforcement
Operant Extinction (EXT)
Contingency between the response and reinforcer is broken
Underlying mechanism of extinction
Withhold all attention following the response
Extinction procedure for behavior maintained by attention
Deny access to item following the response
Extinction procedure for behavior maintained by access to tangibles
Mask the sensory consequences of the response
Extinction procedure for behavior maintained by sensory effects (automatic)
Continue the demand following the response until task is completed
Extinction procedures for behavior maintained by escape
Unwanted effects of extinctions x4
- Extinction burst
- Extinction-induced aggression
- Behavioral contrast
- Spontaneous recovery
Brief increase in response variabilitiy following extinction
Extinction burst
Violent acts directed at the previous source of reinforcement
Extinction-induced aggression
Increase responding in settings uncorrelated with EXT
Behavioral contrast
Random reoccurrence of previously reinforced behavior
Spontaneous recovery
3 strategies for minimizing the unwanted effects of EXT
- Combine with other procedures
- Switch to CRF schedule for problem behavior
- Identify response class hierarchies
3 strategies for mitigating unwanted effects of EXT:
- Inform caregivers of unwanted effects
- Provide caregivers with procedures
- Withhold reinforcer if spontaneous recovery occures
3 other factors to consider when using EXT
- Length of reinforcement history
- Baseline schedule of reinforcement
- Baseline parameters of reinforcement
Two effects of differential reinforcement
- Differentiation
2. Discrimination
R1 = SR R2 = EXT
Differentiation
S1 - R1 = SR
S2 - R1 = EXT
Discrimination
Reinforcement is delivered at the end of a time interval for absence of target behavior
DRO
DRO Interval Criterion
50% to 80% below the average baseline IRT
3 general types of DRO schedules
- Interval DRO
- Momentary DRO
- Progressive DRO
Reinforcement is delivered at the end of the interval if no target behavior at that exact moment
Momentary DRO
Reinforcement is delivered at the end of the interval contingent on zero occurrences of the target problem behavior during the entire interval
Interval DRO
Progressively greater amount of reinforcement is delivered for each interval criterion met
Progressive DRO or DRO-P
9 common DRO mistakes
- DRO for low rate of behavior
- DRO interval above average IRT
- Failing to reset timer if problem behavior occurs
- Inconsistent and extra criteria for problem behavior
- Accidentally reinforcing other problem behavior
- Reinforcing “dead person’s” behavior
- Failing to select a competing reinforcer
- Using the same reinforcer to satiation
- Failing to use EXT for problem behavior
Reinforcement is delivered for a response physically incompatible with the target behavior
DRI
