Q
The Purpose of a Language Assessment
A
- Determine the Operant level of a child’s verbal (and related) skills
- Compare to typical language development data
- Identify language acquisition & learning “Barriers”
- If & where to begin intervention (placement)
- Establish IEP Goals
- Design an individualized curriculum/intervention program
- Teaching Strategies
- Is the intervention prog Working? Why/why not?
- A tool to demonstrate learning, track Progress make changes, provide outcome measures
12
Q
Traditional Language Assessment
A
- Cognitive and/or biological variables seen as the primary sources of Control for verbal responses
- Based on the expressive-receptive distinction, mediated by cognitive processors
- Norm referenced & Standardized assessments
- Peabody pic vocal test
- Expressive one-word vocabulary test
13
Q
Behavioral Language Assessment
A
- The verbal operant is the functional Unit (form & function)
- Environmental variables are viewed as the relevant sources of control for verbal responses, rather than cognitive/biological variables
- Each verbal operants involves sources of control (independent variables), thus each must be Assessed
- Most verbal responses are under Multiple sources of control
- More complex VB is comprised of various Combinations of the verbal operants
- Speaker & listener as separate Repertoires
- Criterion-referenced assessment

20
Q
The Importance of Language and Social Behavior
A
- The primary focus of an intervention program for children with autism should be on the development of Effective language & Social Skills
- There clearly are several other areas in need, such self-care, visual motor skills, academics, fine & gross motor etc, but language & social skills are typically the most significant Deficits for children with autism & careful Training is the key to the most significant gains
- The failure to conduct an Appropriate assessment results in one of the biggest problems in prog that serve children with autism or other development disabilities. An appropriate Curriculum
21
Q
The Behavioral Classification of Language (Skinner, 1957)
A
- Mand: Asking for reinforcers. Asking for “shoes” because you want your shoes
- Tact: Naming/identifying objects, actions, events etc. Saying “shoes” because you see you shoes
- Listener: Following instructions/complying with the mands of others. Touching a picture of shoes when asked “Touch the shoes”
- Echoic: Repeating what is heard. Saying “shoes” after someone else says “shoes”
22
Q
The Behavioral Classification of Language
Contd….
A
- Imitation: Copying someone’s Motor movement (as they relate to sign language)
- Copying-a-text: Writing “shoes” cuz some1 else writes “shoes”
- Intraverbal: Answering ques or having conversations where ur Words are controlled by other words. Saying “shoes” cuz some1 else says “what do you need to put on ur feet?”
- Textual: Reading words. Saying “shoes” cuz you see the written word “shoes”
- Transcription: Writing & spelling words spoken to you. Writing “shoes” cuz you hear “shoes” spoken
23
Q
Problems with the ABLLS (Partington & Sundberg, 1998)
A
- A significant improvement over Spradlin 1963; Sundberg, et al, 1979; Sundberg, 1983, 87, 90
- Too many Skills to assess (476, over 1500 cell with the 1-4 criteria)
- Steps on the cells were too Small for IEP goals (Milestones are better)
- Skills not developmentally Balanced out on the grids
- Much of it is out of Developmental sequence (as I see it now)
- Core sequence of verbal skills if 26 yr old (Sundberg, 1983)
- Just a listing of skills with e.g. & a scoring criteria
- Confusing progression of skills; up/out?
- No Content on wat constitutes Mands, Tacts, Intraverbals etc
- No Content on what constitutes Mands, Tacts, Intraverbals etc
- No content/text on how to Conduct a VB analysis
24
Q
Problems with ABLLS
Partington & Sundberg, 1998
A
- Not a “curriculum” for language intervention “curriculum Guide”
- Originally, the ABLLS was designed to Accompany the “Teaching Language to Children with Autism” book (The ABLLS was not designed to serve as a stand alone product)
- Not enough info in the individual cells to explain the skill being assessed & the relevant sources of control (e.g. noun-verb tacting, mands for info, multiply controlled intraverbal bx)
- No VB analysis of language & learning barriers (a major component of assessment)
- No Placement system (e.g. when to start IV)
- No Transition assessment
25
An assessment based on VB assesses:
a) All of the elementary verbal operants & other language related skills such as matching, social Bx, play skills & listener skills
b) Only the verbal operants
c) The linguistic structure of English
d) Expressive & receptive language
a) All of the elementary verbal operants & other language related skills such as matching, social Bx, play skills & listener skills
26
The failure to adequately assess a child's language & related skills, & his language & learning barriers often results in:
a) Self-injurious or aggressive Bx
b) An inappropriate language & social skills curriculum
c) The need for more extensive services
d) A less expensive program
b) An inappropriate language & social skills curriculum
27
Verbal Behavior Milestones Assessment and Placement Program:
The VB-MAPP

VB Milestones Assessment and Placement Program:
The VB-MAPP Barriers Assessment
- Imp to find out what child can do, but also Can't do & why?
- VB-MAPP barriers assessment is a tool designed to Identify & score 24 different learning & language acquisition barriers
- 1ce specific barrier identified - detailed FA required
- many ways Verbal repertoire/related skill can become Defective & individualized analysis necessary to determine nature of prob for specific child & wat intervention prog might be appropriate
51
Verbal BX Milestones Assessment and Placement Program:
The VB-MAPP Barriers Assessment
Defective Verbal BX
- A descriptive Functional Analysis of VB
- A bx analysis of words, phrases & sentences emitted by children with autism
- Same basic principles of bx as Nonverbal bx
- What is source of control?
- These sources of control often reveal wat appears to be correct response in Form is actually incorrect in function
- Might not be the same source of control observed in a typically developing child
- Each verbal operant can be susceptible to Unwanted sources of control
52
Verbal BX Milestones Assessment and Placement Program:
The VB-MAPP Barriers Assessment
- Defective Mands
- Defective tacts
- Defective Intraverbals responses
- The Bx analysts must determine wat the correct source of control should be, & how tht source can be established
- The FA of VB is on-going
- The failure to conduct such an analysis may result in rote/defective Verbal repertoires tht can become difficult to Change
- This is hoe Bx analysis is different this is wat we do as BX analysts
53
Verbal BX Milestones Assessment and Placement Program:
The VB-MAPP Barriers Assessment
*Common Learning & Language Acquisition Barriers
- Instructional control (Escape/avoidance)
- Bx problems
- Defective mand
- Defective tact
- Defective motor imitation
- Defective motor imitation
- Defective Echoic
- Defective matching-to-sample
- Defective listener repertoires
- Defective intraverbal
- Defective play & Social skills
- Scrolling responses
- Failure to make conditional discrimination
- Failure to generalize

54
Verbal BX Milestones Assessment and Placement Program:
The VB-MAPP Barriers Assessment
*Scoring the VB-MAPP Barriers Form
- Rate the child on the VB-MAPP Barriers Assessment Form using a Likert-type scale 0-4
- A score of 0 or 1 would indicate that there are no Significant barriers & a formal intervention plan may not be required
- A score of 2-3 or 4 would indicate that there is a barrier tht probably should be addressed as part of intervention
- For some children the immediate focus of intervention prog is on removing a particular barrier, rather then lang instruction
- most common immediate barriers to remove involve instructional control prob or other BX prob
55
The VB-MAPP Barriers Assessment uses a Likert Scale designed to identify:
a) Potential language & learning problems that are preventing a child from making greater gains
b) How long it takes to acquire new skills
c) Expressive & receptive language barriers
d) How to transition a child to a less restrictive env
a) Potential language & learning problems that are preventing a child from making greater gains
56
Once a barrier has been identified on the Likert scale the next step is to:
a) Write a report
b) Conducting the VB-MAPP transition Assessment
c) Design a punishment procedure for the most intrusive barrier
d) Conduct a descriptive or functional analysis of the problem
d) Conduct a descriptive or functional analysis of the problem
57
Many children with autism:
a) Are effected by 1 or 2 barriers
b) Are not affected by barriers
c) Maybe affected by 5 or more barriers
d) Are affected by all the barriers
c) Maybe affected by 5 or more barriers
58
The main task in identifying the nature of a barrier is to:
a) Determine the child's intentions
b) Conduct a psychological test
c) Identify the sources of antecedent & Consequent control
d) Obtain content for a written report
c) Identify the sources of antecedent & Consequent control
59
Barriers are common for children with language delays & often:
a) Only the tact is affected by barriers
b) Only matching-to-sample is affected by barriers
c) Removing the barrier should be the immediate focus of the intervention prog
d) The barrier will go away by itself
c) Removing the barrier should be the immediate focus of the intervention prog
60
An impaired many maybe demonstrated by:
a) The same word or sign (e.g. more) being used for all sources of motivation
b) A mand that is only controlled by motivation
c) A mand that occurs spontaneously
d) A mand that does not stop until it gets reinforced
a) The same word or sign (e.g. more) being used for all sources of motivation
61
An impaired matching-to-sample repertoire maybe related to:
a) Defective cognitive processing
b) A low IQ
c) Apraxia
d) The failure to scan the visual array
d) The failure to scan the visual array
62
An impaired tact repertoire maybe due to:
a) Failing to teach matching-to-sample repertoire
b) Teaching verbs, adjectives and prepositions before tacts of nouns are well established
c) Poor cognitive processing
d) Aphasia
b) Teaching verbs, adjectives and prepositions before tacts of nouns are well established
63
The VB-MAPP Transition Assessment
- A common Goal for many educators & parents of children with special needs is to integrate the child into a mainstream setting
- There are many diff levels of integration and the Transition Assessment was designed to identify the skills tht increase the probability tht a child will be successful in less restrictive setting
- No single skill will be good determiner of success but a collective body of skills can help educates & parents make decisions
- The VB-MAPP Transition Assessment provides a tool to help determine if a child has necessary prerequisite skills to learn in less restrictive classroom env
- There are 18 skill areas on the Transition Assessment
64
The VB-MAPP Transition Assessment was designed to:
a) Determine if a child can move well btw teaching sessions
b) Be used in litigation & fair hearings
c) Provide some data for making decisions regarding the type of educational prog that might best benefit a child
d) Determine if a child need VB training
c) Provide some data for making decisions regarding the type of educational prog that might best benefit a child
65
The VB-MAPP Transition Assessment covers:
a) Only the summed scores from the Milestones & the Barriers Assessment
b) Scores for 18 different skill areas
c) A summation of all assessments from a 3-yr evaluation
d) A functional analysis of Bx problems
b) Scores for 18 different skill areas
66
The VB-MAPP
Task Analysis & Skills Tracking
- The Milestones can be considered floors in a building, & the task analysis contains the Steps btw each floor
- There are 170 milestones & approx 900 total tasks in the VB-MAPP task analysis
- The task analysis form also allow for more Detailed skills tracking
- Building a whole Repertoire not just Individual skills (e.g. mand. tact, M-T-S repertoire)
67
The VB-MAPP Transition Assessment is scored by using:
a) A Likert type scale
b) Converted IQ scores
c) The results of a functional analysis
d) The results of a speech & language evaluation
a) A Likert type scale

a) The class teacher along with a Board Certified Bx Analyst
b) School district administrators
c) The child's parents
d) The IEP team as a whole
d) The IEP team as a whole
70
Verbal Behavior Milestones Assessment and Placement Program:
IEP Goals and Placement
- The results of the VB-MAPP Skills and Barriers Assessment provide Guidance for the development for an Intervention prog
- Specific IEP Goals are provided for each milestone & barrier
- The assessment Corresponds with the VB intervention prog
71
What is Intraverbal BX?
- is a type of VB where Form of the response is under the Functional Control of antecedent verbal discriminative stimulus (Sd) & some type of generalized conditioned RX
- The verbal stimulus & the verbal do no Match each other
72
Intraverbal BX
- A young Child Early intraverbal BX maybe relatively simple such filling in the words of songs for Fun activities
- These responses maybe Multiple controlled (e.g. MO)
- But intraverbal BX soon becomes quite Complex & a significant part of a developing child's daily VB
73
How is the Intraverbal Different from the Mand, Tact & Echoic?
Antecedent -> BX-> Consequence
* MO -> Mand -> Specific RX
* Nonverbal Sd -> Tact -> Generalized RX
* Verbal SD (with match) -> Echoic -> Gen RX
* Verbal Sd (w/o match) -> Intraverbal -> Gen RX
74
Common Intraverbal Problems Experienced by Children with Autism
- Absent/weak intraverbal Bx, despite strong mands, tacts & listener skills
- Rote intraverbal responses
- Difficulty ans que --esp Complex ques
- Excessive rote Scripting
- No Conversational skills
- Echolalia with intraverbal ques
- Poor Peer intraverbal interaction
- Irrelevant intraverbal Bx
- Self as a listener with overt intraverbal Bx
75
Why the Intraverbal Repertoire maybe Absent, Weak or Impaired
* There are many potential Causes of intraverbal prob. Here are a few:
- Child has not received formal Intraverbal training
- Child is given training but it's too Early to focus on intravervals
- Are not in child's repertoire
- Single Verbal stimuli & single verbal responses has been Over conditioned
- The intraverbal curriculum is out of Developmental sequence
- The child doesn't have sufficient training on Verbal conditional discriminations
76
Conditional Discriminations
- "What the nature or extent of operant control by a stimulus condition Depends on some other stimulus condition:
- One discriminative stimulus or MO alters the evocative effect of a second stimulus & establishes the second stimulus as an Sd or MO & they collectively evoke a response
77
Verbal Conditional Discriminations (VC)
- What Constitutes a Verbal conditional discrimination & an intraverbal response?
- 2 components of a verbal stimulus where one verbal stimulus alters the evocative effect of the second verbal stimulus & collectively they evoke a differential intraverbal response
- Skinner calls this a "compound verbal stimulus" but does not use the term "verbal conditioned discrimination"
78
Verbal Conditional Discriminations (VCd)
*Antecedent -> Intraverbal Response
*Some e.g include:
- Big animal -> Lion
- Little animal -> Mouse
* VCd = VSd alters the Evocative effect of Vid or vice versa
* A correct response is Dependent on VC btw words, if individual words are the source of control errors will occur
79
Teaching Intraverbal BX to Children with Autism
- Many children with autism have a difficult time acquiring intraverbal bx bcuz beyond Simple intraverbals, most intraverbal responses are part of a VCdS
- For e.g. What's you cat's name?, What's my cat's name? What did the cat chase?
80
Most intraverbal Bx requires:
a) Extensive auditory processing
b) Verbal conditional discriminations
c) A strong motivate variable
d) A nonverbal env to talk about
b) Verbal conditional discriminations
81
A verbal conditional discrimination involves:
a) Both a verbal stimulus & a verbal response
b) A nonverbal response that is evoked by two verbal stimuli
c) A verbal stimulus that is part of a matching to sample discrimination
d) A verbal stimulus that alters the evocative effect of another verbal stimulus
d) A verbal stimulus that alters the evocative effect of another verbal stimulus
82
Two main reasons why why intraverbal Bx might be problematic for a child with autism are that:
a) The related tact skills are not strong in the child's repertoire, & he may not have an MO to learn intraverbals
b) There is not enough teaching time spent on intraverbal Bx, & it is incompatible with the standard DTT format
c) Intraverbal training is often not part of the intervention prog, or the intraverbal curriculum used is out of a developmental sequence
d) Staff are unaware of how to teach intraverbal bx, & the child can not learn it due to autism
c) Intraverbal training is often not part of the intervention prog, or the intraverbal curriculum used is out of a developmental sequence
83
Many children with autism:
a) Fail to acquire much significant intraverbal Bx
b) Demonstrate an intra verbal repertoire commensurate with their typically developing peers
c) Acquire intraverbal bx before Manding
d) Acquire intraverbal bx through reading
a) Fail to acquire much significant intraverbal Bx
84
The interaverbal needs to be assessed separately from the Mand, Tact & Echoic because:
a) The intraverbal is controlled by a completely different set of antecedent variables
b) The intraverbal is much harder for children with autism
c) The intraverbal is controlled by nonverbal stimuli
d) The intraverbal is controlled by motivational variables
a) The intraverbal is controlled by a completely different set of antecedent variables
85
Typical children begin to emit intraverbal bx when they are about:
a) 1 yr old
b) 2 yr old
c) 3 yr old
d) 4 yr old
b) 2 yr old
86
Current Study
- Is there a general Sequence of increasingly complex verbal stimuli & VCdS that can be used for assessment & intervention?
- When are typically developing children successful at these tasks?
- A Revised version of the 80-item intraverbal subtest of the VB-MAPP was designed with increasingly complex intraverbal tasks, This version was modified as Function of previous field-test data
- This is 3rd large-scale administration of the VB-MAPP IV subject
87
Results and Error Analysis for the Typically Developing Children
1-2 yr old
- 1 1/2 yr old: 20-30 mands & tacts, IV Assessment scores: Less than 5, Generally no IV bx
- 2 yr olds 100-200 range, IV Assessment scores 10-30 range, Some Intraverbal bx, can do fill in songs, animal sounds, common fill on, limited WH ques, lots of echoic repose
88
Results and Error Analysis for the Typically Developing Children
21/2 yr olds
- 200-400 mands & tacts
- IV Assessment scores: 20-40 Range
- Some Simple intraverbal bx, getting some easy WH ques, minimal VCds
- Frequent Echoic responding or "What" "I don't know" "Things" when some intraverbal Control was demonstrated often simple IV relation minimal verbal conditional discriminations, the Last or prominent word usually the Source of stimulus control
- What goes on ur head? Shoulders
- What helps a flower grow? UP
89
Results & Error Analysis for the Typically Developing Children
3 yr olds
- 500-1000 mands & tacts
- IV Assessment scores: 40-60 range
- Well Established basic intraverbal repertoire, 100s of IV relations
- But verbal conditional discrimination Errors were prevalent
- "What grows on ur head? Planta
- Many of WH ques cause prob
- Where do you wat? ...Food
- ROTE response were equal: What day is today? "Rainy" (it was sunny)
90
Results and Error Analysis for the Typically Developing Children
3 yr old (Contd....)
- Problems with prepositions, adjectives, adverbs in VCdS
- Wat's under a house? Roof
- What is something that is Sharp? Giraffe
- What's something you can't wear? "shirt"
- 3 causes of errors: VCdS, Complexity of the different parts of speech & meanings of individual words
91
Results and Error Analysis for the Typically Developing Children
3 1/2 Yr olds
- 500-1200 mands & Tacts
- IV Assessment scores 50-70 range
- Verbal Conditional discrimination errors were still common
- What grows on ur head? "Hat"
- Name some clothing.... for the body
- Negation still a major major prob
- Still having prob with, prepositions, adjectives, adverbs in VCDs
- Still problems with Time concepts
- Still emitted Echoic responses when no intraverbal occurred
92
Results and Error Analysis for the Typically Developing Children
-4 Year olds
- 800-1800 mands and tacts
- IV Assessment scores: 50-75 range
- Verbal conditional discrimination errors were still Common
- What do you smell with? ..."A skunk"
- But VCDs are clearly getting stringer
- What's above a house? An airplane & stuff that's on the roof"
- Negation time concepts, preposition & adjectives in a VCDs contd.. to be a prom for many children
- Specific words and concepts like "different" "btw "take" "how" and why? caused prob
93
Results and Error Analysis for the Typically Developing Children
5 yr olds
- 1000-2500 mands and tacts
- IV assessment Scores 55-76 range
- They get it! They are much better at VCDs
- "What's in a balloon?" ...Helium, Air
- However, they still have Problems with negation time concepts and prepositions
- Many Children Missed "What day is today?" "What day is before Tuesday?" "What's ur last name?"
94
Error Analysis for the Children with Autism
- The children with autism made the Same Types of errors as typical children who scored at their level
- Verbal conditional discriminations were hard for All children esp those involving "WH" eyes & the different parts of speech
- Rote responding was more obvious & more Firmly established
- Echoic responses were more Frequent
- Neg Bx was higher with increasing complexity of the verbal stimulus
95
The VB-MAPP intraverbal subtest contains:
a) 200 questions that all begin with "WH" words
b) The core part of most IQ tests
c) A cognitive processing probe
d) A sample of 80 intraverbal tasks are developmentally sequenced
d) A sample of 80 intraverbal tasks are developmentally sequenced
96
The primary goal of the VB-MAPP intraverbal subtest is to:
a) Meet the requirements for standardized tests
b) Trick the child with hard ques
c) Determine a child's intraverbal level as compared to typically developing children in order to develop an appropriate intraverbal intervention prog
d) Determine a child auditory processing errors
c) Determine a child's intraverbal level as compared to typically developing children in order to develop an appropriate intraverbal intervention prog
97
The grids on the VB-MAPP Task Analysis:
a) Puts all the skills from a specific skill area together on a single bar chart
b) Breaks up the skills into tree developmental levels, & frames them by the Milestones
c) Cannot provide any visual info on the balance of the skills
d) Do not allow for developmental comparisons across skills
b) Breaks up the skills into tree developmental levels, & frames them by the Milestones
98
Errors Made by Typically Developing Children & Children with Autism scoring at the Same Level
- IV Assessment Score of 0-19
- Typically developing children & children with autism who autism scored at this level emitted similar errors
- Gave an Echoic response to the ques
- Gave no Ans
- Gave a Standard single ans like "yeah" or "yes"
- Pointed at something or pointed in some location (listener Bx)
- Neg Bx was Higher for children with autism (Avoidance & Escape)
99
Implication for Intraverbal Intervention Programs
- Use the acquisition of intraverbal Bx of typically developing children as a Guide for an intraverbal curriculum
- Assess a target child's existing intraverbal repertoire using a tool like the one presented here
- Look for Balance across the scores of the VB-MAPP
- Assess the Corresponding Mand, Tact & Listener repertoire & be assured they are present prior to intraverbal training
- Carefully Sequence the intraverbal tasks
100
Implication for Intraverbal Intervention Programs
- Typically developing 3-yr olds emit 1000s of intraverbal responses a Day thus there needs to be many trials for language delayed children
- Don't move from the nonverbal context too Quickly
- Don't be in a rush to move up the Curriculum
- There is a need for Massive verbal stimulus & response Generalization
- Use LRFFC as a stepping stone to IV
- Always analyze Errors & the sources of control. Back Down the curriculum sequence if necessary
- Mixed & rotated VB trials on one topic mimic general conversation & provide a bridge to the Natural use of the skill
101
Implicati
| on for Intraverbal Intervention Programs
- Respect the complexity of verbal Conditional discriminations (VCDs)
- Establish a strong repertoire of Simple intraverbal relations prior to moving to VCDs & WH ques
- Be aware tht a (rote) Correct ans to a ques may occur when the VCDs element is removed. Mixed and rotated VB trials can solve tht prob
- Be assured that the Individual words evoke generalized intraverbal response prior to combining them in a VCDs talk
102
Conclusions
- The intraverbal BX of typically developing children can serve as an imp Guide for an inter verbal Curriculum for children with autism autism/other development disabilities
- The primary Behavioral relation relevant to intraverbal Bx almost Always involved a Verbal conditioned discrimination
- Children with autism made the Same intraverbal errors as typical children who scored at their level
- A behavioral analysis of these verbal Errors can help us better understand the errors made by children with autism & Avoid those errors by better sequencing the curriculum tasks & by providing the necessary instruction esp on VCDAs
103
Conclusions (Contd...)
- There is very Little behavioral Research on VCDs & their relation to intraverbal Bx
- Existing conditional discrimination research can serve as a guide for VCSintraverbal research
104
