Autism

  • Developmental disability that includes delays in:
    • Social interactions
    • Skill acquisition
    • Communication

4 of 24

Child

  • 3 years old
    • Diagnosed with autism
    • Robust skill acquisition
    • Interacts with adults and peers
    • Poor communication skills
      • Defective requesting skills (manding)
      • Difficult to understand

Manding

  • A behavior analytic term for “requesting”
    • i.e. deMAND, comMAND
  • Can include many topographies
    • Vocal
    • Picture Exchange
    • Signing

“Cupcake”

Manding

  • Manding is controlled by
    • A state of deprivation or aversive stimulation
      • i.e. you haven’t had a drink of water in a while
      • i.e. pain
    • Usually specifies it’s reinforcer
      • i.e. “can I have some water, please.”

For Example

“Boy, it’s hot out. I’m thirsty.”

“Lemonade, Please!!”

Pivotal Response Model

  • Pivotal Response Model:
    • Use natural learning environment
    • Create learning situations
    • Results in improved social and communication skills

What is a Pivotal Response?

  • Pivotal Response:
    • Mastered behaviors that evoke positive changes
    • Allow contact with other learning situations
    • Examples:
      • Motivation
      • Self-management
      • Self-initiations

Pivotal Response Training

  • Over 14 years of evidence-based research
    • Model developed by Drs. Robert and Lynn Koegel
    • Comprehensive program
    • Based on the principles of behavior

Teaching Manding - Procedure

  • Daily seven-minute sessions
  • Led by child in a preferred play area
  • Access to preferred items (toys, activities) were dependent on a vocal mand
  • Shaping was used to establish approximations
    • Accepted approximations
    • Slowly increased difficulty

12 of 24

Targeted Mands

  • Grocery Cart (Cart)
    • “ca”, “car”
  • Puzzle
    • “puh”, “puh-puh”

13 of 24

Pre-test/Baseline

  • Seven-minute session
  • Led by child in preferred play area
  • Access to preferred items/activities blocked
  • Asked “What do you want?”
    • Scored 0%, no correct responses

14 of 24

Pre-test/Baseline

“What do you want?”

“DA!”

15 of 24

Mand Training

  • Daily seven-minute sessions
  • Led by child in preferred play area
  • Access to preferred items/activities blocked
  • Asked “What do you want?”
    • Provided an immediate verbal prompt

16 of 24

Mand Training

“What do you want?”

“CART!, CART, CART”

“CA!”

17 of 24

Mand Training Cont.

  • Correct Response (+)
    • Child vocalizes or approximates name of item
      • Within five seconds of the verbal prompt
    • Approaches and interacts with requested item
  • Incorrect Response (-)
    • Child doesn’t vocalize or approximate name of item
      • Within 5 seconds
    • Doesn’t interact with requested item

18 of 24

Mand Shaping

  • Once approximations occurred reliably
    • 2 sessions at 90% or 3 sessions at 80%
  • Increased difficulty of approximation
    • i.e. (“puh” to “puh-puh”)

Discussion

  • Procedure was effective
    • Child learned targeted words
  • Manding generalized to other tutors
  • Observed non-targeted mands

22 of 24

Maintenance

  • Procedure into daily schedule
    • December 2012
  • Faded prompts and question

23 of 24

Future Directions

  • Recently diagnosed with Apraxia
    • Oral/Motor speech disorder
    • Difficult to understand
  • Increase amount of vocal/verbal procedures
  • Requiring vocal mands for items throughout day
