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?
