Chapter 1: Basic Principles
Chapter 1: Slide 3
Chapter 1: Slide 4Copyright © 2011 by Springer Publishing Company, LLC
Basic Principles
What is wrong with traditional interpretations about problem behavior?
Is the role of environmental/context variables trivialized?
Chapter 1: Slide 5Copyright © 2011 by Springer Publishing Company, LLC
The Cornerstone for Understanding Why: Maintaining Contingencies
Behavior serves a function. He does it (tantrum) because he has
autism, negates an analysis of contextual factors.
Chapter 1: Slide 6Copyright © 2011 by Springer Publishing Company, LLC
Two Types of Contingencies
Positive reinforcement operations Negative reinforcement operations
There are 2 ways of producing either of these contingencies:
Directly or Indirectly (socially mediated)
Chapter 1: Slide 7Copyright © 2011 by Springer Publishing Company, LLC
Direct Access (DA) Behaviors
With a direct access behavior, the client's behavior immediately produces access to positive reinforcement
In other words, the behavior produces the positive reinforcer
Chapter 1: Slide 8Copyright © 2011 by Springer Publishing Company, LLC
Socially Mediated Access (SMA) Behaviors
Other behaviors achieve their effect through the behavior being mediated by someone else.
These behaviors produce the desired positive reinforcer through the efforts of someone else.
Chapter 1: Slide 9Copyright © 2011 by Springer Publishing Company, LLC
Direct Escape (DE) Behaviors
Behavior can also produce direct termination of existing environmental events, serving a direct escape function.
Such behavior is strengthened in its ability to terminate such events when those events are present.
Chapter 1: Slide 10Copyright © 2011 by Springer Publishing Company, LLC
Socially Mediated Escape (SME) Behaviors
Escape behaviors can often achieve their effect of removing or postponing an aversive condition through the behavior of someone else.
Chapter 1: Slide 11Copyright © 2011 by Springer Publishing Company, LLC
EO’s: The Antecedent Context
MO’s for behaviors maintained by positive reinforcement
MO’s for behaviors maintained by negative reinforcement

Conducting a Functional Target Behavior Assessment (FBA)
Methods
Chapter 2: Slide 14Copyright © 2011 by Springer Publishing Company, LLC
The Purpose of an FBA
To determine environmental function(s) of target behavior(s).
When function of target behavior is determined, a functional treatment can be designed.
Behavioral function cannot solely be gleaned from rate of occurrence or duration data.

Preview of FTBA Data Collection Methods
Behavioral interviewing Scatter plot data A-B-C descriptive analysis Analogue assessment (aka FAB) In-vivo hypothesis testing
Chapter 2: Slide 16Copyright © 2011 by Springer Publishing Company, LLC
Behavioral Interviewing
Attempts to discern controlling variables, both antecedent and consequent, by interviewing direct line personnel or care providers
Uses possible hypotheses about target behavior as basis for questions to staff persons or parents, e.g., if you thought the behavior might be maintained by tangible reinforcers, how would you frame interview questions?
Chapter 2: Slide 17Copyright © 2011 by Springer Publishing Company, LLC
Four Questions to Consider in Evaluating Behavioral Interview Data
Does the problem behavior appear to reliably produce the hypothesized contingency?
Is the problem behavior more efficient and effective at producing such a contingency in contrast to other behaviors?
Chapter 2: Slide 18Copyright © 2011 by Springer Publishing Company, LLC
Four Questions to Consider in Evaluating Behavioral Interview Data (continued)
In the case of positive reinforcement contingencies, does the behavior usually occur in the absence of the target behavior? (note this is the EO involving deprivation)
In the case of negative reinforcement contingencies, does the target behavior usually occur in the presence (or advent) of the aversive, undesired event or object? (EO involving presentation of aversive stimuli)
Chapter 2: Slide 19Copyright © 2011 by Springer Publishing Company, LLC
Did You Ask These Questions?
Why does she or he behave that way? Why does she or he do that?
Chapter 2: Slide 20Copyright © 2011 by Springer Publishing Company, LLC
Scatter Plot Data
Target behavior(s) as a function of context
Chapter 2: Slide 21Copyright © 2011 by Springer Publishing Company, LLC
What is a Scatter Plot?
Plots frequency of target behavior as a function of: time context activities
Chapter 2: Slide 22Copyright © 2011 by Springer Publishing Company, LLC
To Use Scatter Plot Data
Examine frequency of problem behavior across days of the week and look for: patterns of high frequency or occurrence patterns of low frequency or non-occurrence see sample scatter plot data in next slide

Scatter Plot Data: Tantrums (T) & Property Destruction (PD) Descriptive Analysis
Done in real time, soon after the behavior has occurred
Trained observer makes it more reliable, although not as reliable as analogue assessment or in-situ hypothesis test
For infrequent behaviors, a trigger analysis can be conducted, making antecedent conditions more specific
Examine data for patterns of socially mediated contingencies following behavior, or if direct result of behavior seems plausible

Experimental methods analogue assessment in-situ assessment
Chapter 2: Slide 29Copyright © 2011 by Springer Publishing Company, LLC
FAB Protocol, Iwata et. al. (1982)
Implemented in clinic setting Four conditions; mimic hypothesized
contingency demand (escape function) attention (attention function) play/enriched environment (control condition) alone (sensory function)
Chapter 2: Slide 30Copyright © 2011 by Springer Publishing Company, LLC
FAB Protocol, Iwata et. al. (1982) (continued)
Quick switching of test conditions; alternating treatments (multielement) design
Mimic controlling contingency variable in each of the experimental conditions
Consistent and distinctive higher rates in one condition (e.g., demand) indicate probable function (e.g., escape) in non-clinic setting (i.e., real life)
Chapter 2: Slide 31Copyright © 2011 by Springer Publishing Company, LLC
Analogue Assessment: Testing a Hypothesis
Using the function-based diagnostic classification system in Cipani & Schock, it is possible to test a specific hypothesis
For example, let’s say we strongly suspect that a student’s target problem behavior is a function of instruction which is relatively long
Design analogue test that measures behavior under two conditions
Chapter 2: Slide 32Copyright © 2011 by Springer Publishing Company, LLC
Analogue Assessment Testing for Escape/Avoidance of Instruction-Task Duration Diagnosis
Conduct 8 mini-sessions, length up to 50 minutes
Get Same (or similar) materials that are used in class
For 4 sessions, present assignments that last an entire 50 minutes (full=F), i.e., student keeps working until 50 minutes is up. If s/he finishes they get another assignment (or more of the same)
Chapter 2: Slide 33Copyright © 2011 by Springer Publishing Company, LLC
Analogue Assessment Testing for Escape/Avoidance of Instruction-Task Duration Diagnosis (continued)
For 4 sessions, present short assignments that last only 10-15 minutes (short=S). Once assignment is finished, end session, and go to an entertaining activity.
Escape contingency: each time the problem target behavior occurs in either short or full sessions, give the student a 1-2 minute break from the assignment.
Compare rates of problem behavior and on-task behavior between two conditions (compute rate per block of time to equate S and F conditions); higher rates of problem behavior during full condition point to this variable as producing escape (see data next slide).

Analogue Assessment Testing for Escape/Avoidance of Instruction-Task Difficulty Diagnostic
Conduct 8 brief, 20 minute sessions. For 4 sessions – present difficult (D) tasks
(those at grade level). For 4 sessions - present easy (E) tasks (tasks
several grade levels below, make sure student can perform such before test).
Escape contingency: each time target problem behavior occurs, give the student a 1-2 minute break during either test condition.
Compare rates of problem behavior and on task behavior (see next slide).

In-situ Hypothesis Test
Presence of “real life” context variables. Test a hypothesized functional
intervention’s effectiveness in comparison to baseline (i.e., absence of functional treatment).
If intervention results in decrease in target behavior relative to baseline, diagnostic basis of intervention is on more solid ground.
Chapter 2: Slide 38Copyright © 2011 by Springer Publishing Company, LLC
In-Situ Hypothesis Test forFour Diagnostic Categories in School Settings
Baseline Treatment Condition
Teacher attention hypothesis
Baseline condition Teacher attention for replacement behavior
Peer attention hypothesis
No contingency Group contingency (peers) for absence of target behavior
Tangible reinforcer hypothesis
Baseline condition Access to item/activity contingent upon replacement behavior
Escape from instruction-task difficulty
Baseline condition Easy interspersed tasks, 3:1 ratio
Chapter 2: Slide 39Copyright © 2011 by Springer Publishing Company, LLC
Parameters of In-situ Hypothesis Testing
Alternate sessions of baseline vs. treatment.
Conduct data collection in abbreviated session length, not over the entire program.
Collect data on target behavior and replacement behavior across all sessions.

Characteristics of Function-Based Classification System
Diagnoses behavior, not client Provides for prescriptive differential treatment,
utility of classification is in identifying a treatment that matches function
Assesses context variables Assessment phase concludes with a differential
diagnosis

Chapter 4: Functional Treatment that Addresses Functional Diagnosis
Chapter 4: Slide 49Copyright © 2011 by Springer Publishing Company, LLC
Making a Replacement Behavior a Replacement Behavior
Why is this not a functional treatment? A referral is made for a client who hits people
on the shoulder while sitting on the couch and watching TV. The program designer decides that the replacement behavior would be putting his hands in his pockets.

Appendix A: Diagnostic Classification System or the Replacement Behavior (DCS-RB)
3 Major Categories
Appendix A: Slide 55
Appendix A: Slide 56Copyright © 2011 by Springer Publishing Company, LLC
Diagnosing the Strength of the Replacement Behavior
Function-based system identifies why target behavior occurs frequently
Why is alternate (replacement) behavior not occurring at an acceptable rate?
Why is it not functional in the person’s social environment?
Appendix A: Slide 57Copyright © 2011 by Springer Publishing Company, LLC
Diagnosis: Mis-directed Contingencies
Rate of reinforcement is low relative to rate of reinforcement for target behavior, replacement behavior is in repertoire of client/child, but fails to produce desired contingency under specific motivational operation.
Appendix A: Slide 58Copyright © 2011 by Springer Publishing Company, LLC
Treatment for Mis-directed Contingency Diagnosis
Simple differential reinforcement contingencies Disable current target behavior function, enable
replacement behavior function. Not necessary to teach replacement behavior
(unlike next diagnostic category), simply alter the functional reinforcer delivery to be heavily in favor of replacement behavior (enable function) and markedly lower for target behavior (disable function).
Appendix A: Slide 59Copyright © 2011 by Springer Publishing Company, LLC
Diagnosis: Inept Repertoire
Replacement behavior is non-existent (or infrequent) in client’s repertoire, or fluency of response is not adequate to produce reinforcement.
Functional reinforcement contingences are available for such a behavior if it occurred, unfortunately it does not.
Appendix A: Slide 60Copyright © 2011 by Springer Publishing Company, LLC
Treatment for Inept Repertoire Diagnosis
Differential reinforcement alone would be insufficient.
Shaping of alternate behavior required In many functional assessments, writer is
required to specify teaching strategy for developing alternate replacement behavior, not needed for mis-directed contingency diagnoses, but definitely needed here.
Appendix A: Slide 61Copyright © 2011 by Springer Publishing Company, LLC
Diagnosis: Faulty Discrimination
Replacement behavior occurs under a few antecedent contexts (probably due to reinforcement) but not in others that require such a behavior.
