The Roots of a Verbal Behavior Assessment
• Skinner’s analysis of verbal behavior (1957) • Happy 50th Anniversary!• Jack Michael, teacher of Skinner’s analysis of verbal behavior
(starting in 1955)• Joseph Spradlin, applications to the developmentally disabled• “The Parsons Language Sample” (1963)
The Purpose of a Language Assessment
The Purpose of a Language Assessment
The Purpose of a Language Assessment
The Purpose of a Language Assessment
The Purpose of a Language Assessment
• Determine the operant level of a child’s verbal (and related) skills• Compare to typical language development data• Identify language acquisition and learning “barriers”• If and where to begin intervention (placement)• Establish IEP goals• Design an individualized curriculum/intervention program• Teaching strategies (e.g., AC, DTT-NET, inclusion, in-home)• Is the intervention program working? Why or why not?• A tool to demonstrate learning, track progress, make changes,
provide outcome measures
Behavioral Language Assessment
• The verbal operant is the functional unit (form and function)• Environmental variables are viewed as the relevant sources of
control for verbal responses, rather than cognitive or biological variables
• Each verbal operant involves separate sources of control (independent variables), thus each must be assessed
• Most verbal responses are under multiple sources of control• More complex verbal behavior is comprised of various
combinations of the verbal operants• Speaker and listener as separate repertoires• Criterion-referenced assessment
Verbal Behavior Milestones Assessment and Placement Program:
The VB-MAPP
• Based on Skinner’s (1957) analysis of verbal behavior• Based on typical language development milestones • By identifying milestones, as opposed to a task analysis of
individual skills, the focus can be sharper, and the direction clearer• Field test data from approximately 60 typically developing children• Field test data from over 100 children with autism• The body of empirical research that provides the foundation of
Behavior Analysis• Empirical research on Skinner’s analysis of verbal behavior
Verbal Behavior Milestones Assessment and Placement Program:
The VB-MAPP
• There are four components of the VB-MAPP • The VB-MAPP: Skills Assessment contains 165 verbal behavior
milestones across 3 developmental levels (0-18 mos., 18-30 mos., 30-48 mos.), and 16 different verbal operants and related skills
• The VB-MAPP: Skills Task Analysis provides a further breakdown of the 16 different skill areas in the form of a checklist for skills tracking
• The VB MAPP: Barriers Assessment examines 22 common learning and language barriers faced by children with autism
• The VB-MAPP: IEP Goals provides over 200 IEP objectives directly linked to the skills and barriers assessments, and verbal behavior intervention program (Sundberg, in preparation)
Verbal Behavior Milestones Assessmentand Placement Program:
The VB-MAPP Skills Assessment
• The assessment is designed to identify the child’s existing language and related skills
• An assessment should probe a representative sample of a repertoire• Typical verbal milestones can provide the frame for the sample• Typical verbal milestones can help to avoid focusing on only minor
steps• Typical verbal milestones can help to avoid targeting skills for
intervention that are developmentally inappropriate• IEP goals can match the milestones, not individual skills
Verbal Behavior Milestones Assessmentand Placement Program:
The VB-MAPP Skills Assessment
• The 16 skills assessed on the VB-MAPP include:• The elementary verbal operants (e.g., echoic, imitation, mand, tact,
intraverbal) • The listener skills• Vocal output• Play and social skills • Visual perceptual skills, and matching-to-sample• Grammatical and syntactical skills• Group and classroom skills• Beginning academic skills
Verbal Behavior Milestones Assessmentand Placement Program:
The VB-MAPP Skills Assessment
• The milestones are broken into three developmental levels• Level 1: 0-18 months• Level 2: 18-30 months• Level 3: 30-48 months• The scores for each skill are approximately balanced across each
level • There are 5 items and 5 possible points for each skill area
VB-MAPP Level 1: Tact
Verbal Behavior Milestones Assessment and Placement Program:
The VB-MAPP Barriers Assessment
• It is important to find out what a child can do (The VB-MAPP Skills Assessment), but also important to know what they can’t do, and analyze why they can’t do it
• The VB-MAPP Barriers Assessment is a tool that is designed to identify and score 22 different learning and language acquisition barriers
• Once a specific barrier has been identified, a more detailed descriptive and/or functional analysis of that problem is required
• There are many ways that a verbal repertoire or related skill can become defective, and an individualized analysis will be necessary to determine what the nature of the problem is for a specific child, and what intervention program might be appropriate
Verbal Behavior Milestones Assessment and Placement Program:
The VB-MAPP Barriers Assessment
• Common Learning and Language Acquisition Barriers
• Instructional control (Escape/avoidance) • Behavior problems• Defective mand• Defective tact• Defective motor imitation• Defective echoic (e.g., echolalia)• Defective matching-to-sample
Verbal Behavior Milestones Assessment and Placement Program:
The VB-MAPP Barriers Assessment
• Common Learning and Language Acquisition Barriers
• Defective listener repertoires (e.g., LD, LRFFC) • Defective intraverbal• Defective play and social skills• Prompt dependent, long latencies• Scrolling responses• Defective scanning skills • Failure to make conditional discriminations (CDs)• Failure to generalize
Verbal Behavior Milestones Assessment and Placement Program:
The VB-MAPP Barriers Assessment
• Common Learning and Language Acquisition Barriers
• Weak or atypical MOs• Response requirements weakens the MO• Self-stimulation• Articulation problems• Obsessive-compulsive behavior• Reinforcement dependent • Does not attend to people/materials
