Using the Verbal Behavior Approach to Teach Children with Autism Mary Lynch Barbera, RN, MSN, BCBA May 2009 Autism One Conference
My Autism Journey July 2, 1999 – Lucas was diagnosed with moderate to severe autism one day before his third birthday. September 1999 – Started 40 hours/wk ABA program with Lovaas consultant coming monthly. June 2000 – Founding President of Autism Society of Berks. December 2003 – Became a Board Certified Behavior Analyst and Lead Behavior Analyst for the PA Verbal Behavior Project. May 2005 – Published the results of a single subject multiple baseline study that I designed in The Analysis of Verbal Behavior. May 2007 –Publication of my book: The Verbal Behavior Approach: How to Teach Children with Autism and Related Disorders.
Lovaas Study Published in 1987 –59 children (3 years age or under) diagnosed with autism 19 received 40 hours/wk 1:1 ABA for 2 years 20 received 10 hours/wk 20 received standard special education classrooms/OT/speech 47% of those receiving 40 hours/wk of treatment became indistinguishable from their peers by first grade
ABA as the treatment of choice Applied Behavior Analysis (ABA) is the only scientifically validated treatment for autism and is recommended by the U.S. Surgeon General. ABA treatment became popular in the mid-1990s when Catherine Maurice, a parent of two children with autism who both recovered from autism using this approach, published two books detailing Lovaas type ABA therapy.
An Overview of ABA
Applied Behavior Analysis (ABA) Definition Applied behavior analysis is the science in which procedures derived from the principles of behavior are systematically applied to improve socially significant behavior. (Cooper, Heron, and Heward)
Basic Principles of ABA Basic Principles of ABA Behavior is defined in objective and measurable terms Examines the functional relationship between behavior and its controlling variables Analyzes socially significant behavior in need of improvement Analyzes behavior through a three term contingency
Three Term Contingency Antecedent--Behavior-- Consequences ABC Also Described As Discriminative Stimulus--Response-- Consequence MO/S D RReinf. or Punish.
Basic Behavioral Principles Antecedent - any stimulus that happens before a behavior Behavior - an observable and measurable act of an individual Consequence - any stimulus that happens after a behavior
Three (Really Four) Term Contingency Antecedent--Behavior--Consequences Motivation is now seen as playing a significant role in this model (Michael)
Examples of Three Term Contingency Touch nose – Child touches nose – receives piece of cookie Do Puzzle – Child falls to floor – Demand withdrawn
You use the principles of ABA all day long! ABA is used to: –Increase positive behaviors Language, self care skills, academic skills. –Decrease negative behaviors Tantrums, biting, kicking, crying
$1000 Activity Think of a child you know with challenging behaviors: –If I gave you $1000 for that child to have a good day with little to no problem behavior, what would you do?
Pick one or two target behaviors Select the target behavior to be reduced by examining… –The seriousness of the behavior…if could injure self or others…target these before behaviors such as hand flapping or poor attention. –The frequency of the behavior
Define Setting Event Aspects of a persons environment or daily routine that do not necessarily occur immediately before the behavior. –Medication adjustment –Medical problems (pink eye, diaper rash) –Sleep problems –Eating routines/diet –Number of people in room –Daily schedule (how predictable/how much choice)
Immediate Antecedents What triggered the behavior What happened immediately before problem behavior started: Computer was turned off Told child to hang up coat Child saw candy and wanted it
Using the principles of ABA to reduce problem behavior Define Behavior----Be Specific!! Kicking his feet against the chair, throwing books, biting his own fingers, hitting his head with his fist. NOT: Having a tough time, frustrated, irritable
Consequences Reinforcement –A consequence that results in increasing or maintaining the future rate of behavior it follows. Punishment –A consequence that results in decreasing the future rate of behavior it follows.
Consequences Any behavior that occurs repeatedly is serving some useful function and producing some type of reinforcement.
Consequences After a behavior has occurred the environment can change in several ways: 1. A neutral event can happen: if nothing happens that is relevant, the consequence will likely have no effect on the behavior. 2. Things can get better: if things get better, the behavior will likely occur again under similar conditions. This is called reinforcement. 3. Things can get worse: if things get worse, the behavior will likely not occur again under similar conditions. This is called punishment.
Things Get Better: Reinforcement Reinforcement is a change in the environment following a behavior that increases the future probability of that behavior under similar circumstances.
Things Get Worse: Punishment When things get worse following a behavior, the behavior is less likely to occur in the future under similar circumstances. This is punishment. Punishment decreases the likelihood of behavior; Reinforcement (including negative reinforcement) increases behavior.
Is Time Out a Reinforcement or a Punishment? Need to look whether time out is increasing or decreasing the frequency of the target behavior. Most people think Time Out is a punisher but it functions as a reinforcement for many children.
Take Data To Identify the A, B, and C Without taking baseline date and identifying the antecedent, behavior, and consequence, it is not wise to implement a behavior reduction strategy
Functions of Problem Behavior To obtain something desirable (Attention, Tangibles, Sensory Stimulation). To avoid or escape something undesirable (Task avoidance).
Antecedent Interventions Changing the environment before the behavior occurs to prevent the behavior. Focus on pairing/manding 8 positives to every negative Reconfigure class layout or ratio Give more or less time at a center Get more sleep at night or nap Eat breakfast or serve snack earlier Provide transition warnings
Reactive Interventions Interventions implemented after problem behavior occurs. Some examples: –Count and Mand (use for attention only) –Planned Ignoring (use for attention only) –Time Out (use for attention only) –Work through Demand (use for escape only)
Count and Mand Explained in Chapter 2 of my book Used for access to tangibles/attention only! Can also use count and give choice, count and R+, or count and give attention. Steps: 1.Stop the problem behavior (hands down, be quiet, no kicking) 2.Silent count to 3, 5, or 10if problem behavior resumes, return to # 1. 3.Prompt the mand cookiechild echoes cookie Right…how do you ask?…child responds cookie….deliver R+.
Combined Approach Spend 95% of your time preventing problem behavior When negative behaviors do occur, use reactive intervention consequences at the moment. –Count and Mand –Planned Ignoring –Time Out –Work Through Demand
If you find yourself using reactive interventions frequently You need to continue to take data or re- start data taking to determine setting events, antecedents and functions of target behavior Your demands might be too high and/or reinforcement might be too low The environment might need to be changed
Three things that matter no matter what the age or functioning level!! 1.Problem behaviors at or near 0 2.Ability to request wants and needs to an unfamiliar adult 3.Independent toileting ****2-minute activity****
Case Studies Case Study # 1 Amys mother reports that Amy is a poor sleeper. Each Monday morning she arrives to daycare and begins to play. When she is called to circle, Amy cries and throws herself to the ground. The staff tries to find something less aversive to Amy and usually tries bouncing Amy on the ball to get her calm. Amy does usually quiet down on the ball.
Case Study Questions What might be a setting event? What is the immediate antecedent? What is the behavior? What is the consequence? Does the consequence serve as a Reinforcer or Punishment?
Case Study #1 (cont.) Will the behaviors likely go up or down? What is the most likely the function of Amys behavior? What are some interventions you would recommend to help reduce Amys negative behavior
Using ABA and Verbal Behavior (VB) to Increase Positive Behaviors Increasing language and learning skills using the principles of ABA and B.F. Skinners Analysis of Verbal Behavior
What is Verbal Behavior? Behavior that is reinforced through the mediation of another persons behavior
Dual Path of Applied Behavior Analysis Research LOVAAS (UCLA) ABA Research Plus Discrete Trial Training (structure) MICHAEL (WMU) ABA Research Plus Discrete Trial Training Plus Skinners Analysis of Verbal Behavior (function)
Common terms for the Verbal Operants Mand = request Tact = label Intraverbal = conversation, answering a question, responding when someone else talks Echoic = repeating what someone else says Receptive or Listener Responding = following directions
What is Coffee??????? Is it a… MAND? TACT? INTRAVERBAL?
MAND TACT (FFC) RECEPTIVE (FFC) INTRAVERBAL ECHOIC
Verbal Operants Verbal Operant AntecedentBehaviorConsequence MandMotivative Operation (wants cookie) Verbal behavior (says cookie) Direct reinforcement (gets cookie) TactSensory Stimuli (sees or smells cookie) Verbal behavior (says cookie) Non-specific reinforcement (gets praised, for instance) IntraverbalVerbal stimulus (someone says:What do you eat? Verbal behavior (says cookie) Non-specific reinforcement (gets praised, for instance) EchoicVerbal Stimulus (someone says cookie) Verbal behavior: repeats all or part of antecedent (says cookie) Non-specific reinforcement (gets praised, for instance) Receptive (actually not a verbal operant) Verbal stimulus (someone says touch cooke)* Non-verbal behavior (child touches cookie) Non-specific reinforcement (gets praised, for instance)
Verbal Behavior Activity As a result of:One has a tendency to:This is a: Seeing a grapeSaying grape Hearing a hornSaying truck Someone saying what says moo?Saying cow Wanting a push on the swingSaying push Being told to stand upStanding up Someone winnie theSaying pooh Someone says pottySaying potty Seeing a strangerSaying whats your name? Seeing a treeSaying tree
Two other related skills: Imitation: Given another persons motor action in the antecedent condition, the child performs the same action. Match to Sample: matching activities involving either identical or non- identical items. (This is a very simplistic definition for a very critical skill area also referred to as conditional discriminations.)
Teaching the Mand
Why Teaching Mands is Important It helps children avoid frustration in communicating their needs and wants It is relatively easy to do because you are using the childs own motivation as a tool It is a natural first step in teaching communication
The Mand (Requesting) All mands have one thing in common: in the antecedent condition, there is a Motivative Operation (or motivation) in place. A= thirst (MO) B= I want juice C= student gets juice If a child does not want the item, you cannot teach them to mand for it.
Examples of contriving an MO Holding up an M&M within eyesight of the child Giving the child a bottle with a tight lid. In the bottle is his favorite toy. Giving the child a bowl of cereal with no spoon. Giving the child a toy that requires batteries but withholding the batteries Briefly turning on his or her favorite video. Giving a bit of his or her favorite snack to another child.
When Negative Behaviors Occur During Mand Training Do not reinforce whining/crying or other negative behaviors Count and Mand Child has to learn that crying will not get them anything….appropriate manding will!
Keep Number and Effort of Demands Low at First Carefully assess skills Gradually fade in more difficult tasks Avoid escape oriented behaviors: effort and demands should always be outweighed by easy responding Make demands low at first: deliver reinforcement much more often than you ask the child to perform

Recommendations for Mason 1/5/05 Matching Identical Objects/Pictures (F/3) Increase Verbal Imitation using Mand Work on Fill-ins with songs Baseline Labels Set up Mand Sessions (2) 10-minute sessions/day Keep demands low (VR 3 or 4)
Recommendations for Mason 2/25/05 Puzzles/easy toys (shape sorter) Matchingstart categories –make sure he knows tacts of exemplars Prompt him to request actions and missing items Baseline labels (buy flash cards) Mix 80% easy to 20% hard w/VR 3 Continue teaching songs Play doh and coloring RFFC to TFFC to IFFC with item as answer Count and Mand for access to tangibles
Recommendations for Lucas Intensive teaching and NET sessions VR 15 (with 80% easy/20% hard) Teach prepositions/pronouns Teach manding for attention/information Edmark reading program Teach coin and time identification Leisure and self care skills
Thirteen Intervention Tips Thirteen tips based on the science of ABA and BF Skinners analysis of Verbal Behavior that you can start using immediately with all children and adults with language delays and disorders
# 1 – Be Positive 1.Be Positive! Use 8 positives for every negative. Dont overuse the childs name especially when saying no or placing a demand
#2 Pairing 2. Pair yourself and the environment with reinforcement by giving the child lots of reinforcement with no effort required.
# 3 Giving Directions 3. When giving a child a direction Simplify the language Make sure you are close enough and loud enough for him to hear. Get down to childs level to get childs attention Only give directions you can make the child do Give the instruction only once and, if no response, prompt the child to complete the task. Dont give the child a direction youre not willing to follow through with
#4 Reinforcement 4. Look for things that reinforce the child. Set up high interest activities: bubbles, water play, balls, wind up toys to see if any of these are motivators. Put these things out of reach so the child needs you to get them.
#5 Mand Training 5.Teach the child to communicate his needs and wants…first by pulling, reaching…then by using sign language, pictures, or words. Teach 3-5 signs at a time.
#6 Matching 6.Teach the child to match items and pictures. Label the item instead of using the command match or put with same.
# 7 Imitation 7. Teach imitation skills. –With objects/toys. –Gross motor….Pick 2 or 3 movements to target at the same time. Provide as much prompting as needed to ensure the child is successful.
# 8 Receptive Skills 8. Teach receptive skills. Touch body parts, items or pictures…pick 2 or 3 receptive skills… provide as much prompting as needed to ensure the child is successful.
#9 Give Directions You Can Prompt 9. Since you cant force a child to speak, do not use say______ if the child cannot speak or if this is a hard skill. (Say cookie, cookie, cookie as you deliver a small piece of cookie)
# 10 Teach Fill-ins to Songs 10. Use music and familiar nursery rhymes…leave the last word of each line blank to see if child fills it in.
# 11 Sabotage Daily Life # 11 Sabotage Daily Life 11.Sabotage daily life to see if child notices/indicates/or requests: Give cup without juice. Cereal without spoon. Coming upstairs, do not turn off music. Spill milk…dont clean it up immediately. Go a different route in the mall.
# 12 Do Not Reinforce Problem Behavior 12. Do not respond whining, kicking, screaming and other negative behaviors. For problem behavior related to access to attention/tangibles: Walk away, Ignore, or use the Count and Mand procedure For escape related problem behavior: Ignore problem behavior and continue demand
# 13 Prevent and Correct Errors throughout the day! # 13 Prevent and Correct Errors throughout the day! Instructor: Points to an apple and says What is it? Child: bird. Instructor: What is itapple Child: echoes apple Instructor: Right, what is it? Child: apple Instructor: Presents 2-3 easy demands and then what is it? Child: apple
Some Take Home Points for Use With All Children (and Adults) Pairing Manding Once the child can mand for items, ease in demands gradually Prevent and Correct Errors throughout the day Dont reinforce problem behaviors
