CH24 - Functional Behaviour Assessment Flashcards
Functional behavior assessment (FBA)
enables hypotheses about the relations among specific types of environmental events and behaviors.
Behaviors can be strengthened by either “_________” or “____________”
Positive Reinforcement “Getting something”
Negative Reinforcement: “Getting out of something”
These functions can be:
• Socially mediated
• Non-socially mediated (automatic)
Problem Behavior maintained by Positive Reinforcement
Positive Reinforcement
1. Social
• ATTENTION from others
• ACCESS to TANGIBLE stimuli
- Automatic
• Physical STIMULATION
Problem Behavior maintained by Negative Reinforcement
Negative Reinforcement
1. Social
• ESCAPE from aversive or difficult TASKS
- Automatic
• Escape from aversive stimulation
When the function of problem behavior has been identified, intervention can consist of:
Altering antecedent variables
Altering consequent variables
Teaching alternative behaviors
To alter antecedent variables:
Change and/or eliminate
• Motivating operation for problem behavior
• Discriminative stimuli that trigger problem behavior
To altering consequent variables:
Place problem behavior on extinction
• Withhold identified reinforcer when problem behavior occurs
When teaching alternative behaviors:
- Select appropriate behaviors that serve the same function.
* Provide the reinforcer that previously maintained problem behavior contingent upon the new, alternative behavior
FBA can decrease reliance on _______ ____________ and contribute to more effective interventions in several ways
Default technologies
Default technologies
Caregivers might resort to increasingly intrusive, coercive, or punishment-based interventions.
FBA methods can be classified into three types:
(a) functional (experimental) analysis,
(b) descriptive assessment, and
(c) indirect assessment.
Functional analysis:
Antecedents and consequences are arranged so that their separate effects on problem behavior can be observed and measured
Often referred to as ANALOG
• SIMILAR to what is occurring in NATURAL ROUTINE, but more systematic
Typical FA Conditions
- Contingent attention
- Contingent escape
- Alone
- Control (e.g., “free play”)
The primary advantage of functional analysis is its:
Ability to yield a clear demonstration of the variable(s) that relate to the occurrence of a problem behavior.
In a functional analysis graph, If problem behavior occurs frequently in all conditions (including the play condition), or is variable across conditions, responding is considered?
Undifferentiated
Descriptive functional behavior assessment encompasses?
Direct observation of behavior
Three variations of descriptive analysis:
- ABC (antecedent- behavior-consequence) continuous recording
- ABC narrative recording
- Scatterplots.
An observer records occurrences of the targeted problem behaviors and selected environmental events in the natural routine during a period of time.
ABC Continuous Recording
A __________ ___________is the likelihood that a target problem behavior will occur in a given circumstance.
conditional probability
in ABC narrative recording,
(a) data are collected only when behaviors of interest are oberved, and
(b) the recording is open-ended
ABC narrative recording may be less ____-_______
time-consuming
In, ___ _________ _________, the targeted environmental events (antecedents and consequences) are recorded “whenever they occur”, regardless of whether problem behavior occurred with it.
ABC continuous recording,
In, ___ _________ _________, data are recorded “only when the target behavior occurs”.
ABC narrative recording
A procedure for recording the extent to which a target behavior occurs more often at particular times than others
Scatterplots
