9 Functional analysis Flashcards
Often Used for protection. May also prevent the individual from engaging in an alternative activity such as skill acquisition and may also result in physical damage such as shortened tendons due to immobility and adverse Side effects of medication.
Physical and chemical restraints before the use of functional assessments.
Even This approach relied on problematic intervention such as punishment as a way to change her behavior.
Behavior modification
This has resulted in a change in our focus away from those chemical and physical restraints and also away from the use of punishment and allowed us to use more reinforcement procedures.
Functional assessment
Data on the selections of behavioral interventions revealed a gradual decrease in the use of punishment across the years and a dramatic increase in reinforcement based procedures.
Primary benefit of using functional analysis has been to increase the Percision and resulting effectiveness of reinforcement-based interventions
Kahng, Iwata and Lewin 2003
.Reviewed 396 articles from 63 journals, 1965 - 2000.
Around 1990, experimental FA dominates assessment.
the dependant Variable of interest was human behavior and the independent variable was some environmental event of which human behavior was a function
He introduced the Term functional analysis to label the process through which one might go about identifying the independent variables that are functionally related to human behavior. Called
Skinner
Very often when assessing problem behaviors, many of the same environmental events are manipulated. But remember the functional analysis means manipulating an independent variable to measure to measure the effects on behavior. And that can be done in many different ways.
The Standard Functional analysis
Used as part of the process of assessing and treating what’s called behavior disorders
Functional analysis
Catch -all category That simply indicates the repeated occurrence of problematic or maladaptive behaviors
Behavior disorders
If we are going to use this as an assessment tool, there are important assumptions about behavior problems that we have to subscribe to :
First, as behavior analysts we presume that most of our behavior is learned behavior. It’s sensitive to contingencies of reinforcement, and punishment and that stimuli in the environment, like discriminative stimuli, come to influence our behavior through a history of pairing with reinforcement and punishment.
Second, all of our behavior whether it is adaptive or maladaptive is learned through the same sort of consequences. Given that some individuals engage in some behavior that is undesirable, it behooves us to ask WHY are they doing that. That’s what a …….. does. It sets out to answer that question.
Functional analysis
What a behavior looks like tells us nothing about……
Why the behavior is happening
Can tell us the conditions under which the behavior is likely to occur and the conditions under which the behavior is unlikely to occur.
As a result of conducting a functional analysis, leads to improvement in the development of treatment through the identification of antecedent conditions that produce behavior problems., the source of reinforcement to be eliminated, reinforcers that can be used for behavioral replacement and irrelevant or Counter therapeutic treatment.
Functional analysis – FA
The systematic manipulation of environmental variables to determine the effects on behavior began in the late 1960s with research on self injurious behavior or SIB during this time several different researchers examined examined single functions of SAB to determine environmental variables that were associated with higher levels of self injury.
In 1965 Lovass and Colleagues found that SIB increased when it was followed by sympathetic statements, that is Social positive reinforcement in the form of attention increase SIB.
Follow up in 1969. Examine three conditions.
Non-contingent attention- decrease SIB
Contingent attention. -Increased. SIB
Ignore —-Eliminated. SIB
These data suggest that for this child, not only was SIB maintained by attention but it also could be decreased with the use of extinction that is by ignoring it and also reduced by delivering attention for free.
Early functional analysis studies: controlled by a single contingency (SR+)
Carr , 1976, 1980 examined the rate of SIB and aggression under conditions where the man’s were issued and under conditions where demands were not issued.
No programed consequences for SIB in either condition. That is, SIB occurred it was ignored.
Carr found That SIB and aggression were higher in conditions were demands were issued . These studies indicate that problem behavior can be occasioned by demands suggesting that the behavior may be maintained by Social negative reinforcement in the form of escape from demands.
It was suggested because he did not actually provide a scape so can’t know for sure if behavior was maintained by escape because a scape was never delivered.
Early functional analysis studies: controlled by a single contingency (Sr-)
Berkson and Mason. 1963, 1965
Examination of stereotypy
Environment with activities versus environment with no activities.
Stereotopy higher in an impoverished environment
Suggesting that it was not maintained by Social reinforcement, and thereby was likely maintained by automatic reinforcement
When dealing with automatic reinforcement or more loosely, Sensory consequences, we cannot manipulate those consequences because they are directly produced by the behavior itself. Because we can’t manipulate the consequences, we cannot definitively say that a behavior is maintained by automatic reinforcement we can simply say that a behavior is not maintained by Social reinforcement, at least not the ones we tested. Then by default it’s probably maintained by automatic reinforcement That’s why we say a certain pattern of behavior “ suggests” Automatic reinforcement rather than “indicates”automatic reinforcement
Early functional analysis studies: controlled by a single contingency (Auto SR)
In summary these series of studies all demonstrated controlled by a single contingency.
Lovaas SIB increased when followed by sympathetic statements, positive reinforcement.
Carr SIB hire under demand versus no demand conditions.
Berkson mason Sterotypy Higher in impoverished environment compared to when they were in an environment with other activities to do.
