1
Q

What is ASD?

A
  • Etiology remains unknown to date
  • A neurobiological disorder of development; thought to be present at birth
  • Most likely the result of multiple etiological factors
  • Not the result of bad parenting
  • Comorbidity with other conditions (e.g., Down syndrome, fragile-X syndrome, other) can occur.
    -Strong genetic influences
    -higher incidence in siblings
    -social-affective symptoms in other family members
  • Structural brain abnormalities have been found
  • This area of research is mushrooming & changing rapidly with too many areas implicated to attribute ASD to a single structural abnormality
  • Abnormal EEGs in 33-50%

24
Q

1: Antecedent Package

A

Antecedent – BEFORE
Events or things (environmental stimuli or modifications)
Actions of people (prompts) that precede behavior.
Prompting: A prompt(cues, support, or hints) is is help given to a child which assists the child in performing (demonstrating) a skill.
* Prompting forms include:
* Verbal assistance
* Modeling & Gestures
* Physical assistance
Verbal Prompt (Assistance): An adult helps the child complete the targeted skill by telling them what to do or how to do it
Model Prompt: An adult demonstrates or shows the child
the correct sequence or action of the skill by completing
the action or skill themselves when they have the child’s attention.
Gestural Prompt: An adult provides a visual cue for the child to complete a skill (pointing).
Physical Assistance: An adult helps the child complete the actions of the skill by touching and
physically guiding the child to complete the target skill
Full Physical Assistance: An adult helps the child complete the actions of a skill by physically guiding the child through the ENTIRE sequence of the skill
Partial Physical Assistance: An adult helps the child complete the actions of a skill by physically guiding the child through part of the sequence of the skill
Time Delay: A prompting strategy where the instructor starts by immediately providing the child with the prompt necessary to complete the behavior right after he gives the discriminative stimulus. After the child responds correctly with this level of prompting, the instructor systematically increases the amount of time between the discriminative stimulus and the prompt, giving the child more time to respond independently, until the child responds independently without a prompt

25
Q

2: Behavioral Intervention Package

A

Discrete Trial Training (DTT): distinct, repetitive responses following a specific stimulus that result in reinforcement.
* A discrete trial is a single cycle of instruction that may be repeated several times until a skill is mastered
A discrete trial consists of 5 main parts:
1. An initial instruction – ex. “Touch your nose.”
2. A prompt or cue given by the provider to help the child respond correctly – ex. Provider points to child’s nose.
3. A response given by the child – ex. Child touches their nose.
4. An appropriate consequence, such as correct responses receiving a reward designed to motivate the child to respond correctly again in the future – ex. “Nice job touching your nose,” teacher gives child a sticker.
5. A pause between consecutive trials – waiting 1 – 5 seconds before beginning the next trial.
Positive Behavior Interventions and Supports (PBIS):
A values-based AND empirically-valid approach for resolving problem behaviors and helping people lead enhanced lifestyles by simultaneously impacting the targeted behaviors and teaching the child new replacement skills to use.
1. Establishing a Team
2. Conducting Functional Assessment
3. Developing the Intervention Plan (Reducing targeted behaviors + Teaching new (replacement) behaviors)
4. Implementation
5. Evaluations

26
Q

3: Joint Attention

A
  • Parent and child engaging in mutual interest or showing attention to the same object, Activity or Experience
  • Example: Child looking at an item, shifting gaze to a person and then returning gaze to the item.
27
Q

4: Modeling

A
  • Adult or peer provides demonstration of the target behavior
  • Usually combined with prompting and reinforcement
28
Q

5: Naturalistic Teaching

A

Naturalistic Teaching Strategies:
- Present learning opportunities in the child’s natural environment
- Utilize child selected materials/activities
- Utilize the child’s natural motivation and reinforcers
- Used in teaching a variety of socially relevant behaviors
- Expand on individuals use of language
- Incorporate use of commenting about child’s behavior
- Focus on TEACHABLE MOMENTS
Incidental Teaching - Steps
1. Set up the environment
2. Approach - Look/Pause
3. Provide a talk up
4. Withhold access
5. Use general prompt “What do you want?”
6. Use specific prompt
7. Repeat prompt
8. Back up to easier prompt
9. Provide immediate access
10.Provide behavior specific praise

29
Q

6: Peer Training Package

A

Necessitates the presence of typical peers
* Instruction on social skills provided to typical peers
* Addition focus on key components of social interactions (4 turns in a social interaction + Reciprocity)
* Thoughtful Planning of Social situations (Use of social toys and materials)

30
Q

7: Pivotal Response Treatment

A

PRT is based on the idea of teaching FUNDAMENTAL behaviors that lead to generalized gains across a variety of domains.
Key features of PRT include:
* Multiple Cues
* Motivation and,
* Self-management
1. Responsivity to Multiple Cues
* Using a variety of materials for discrimination learning
* Teaches generalization
2. Motivation
* Child choice
* Interspersing maintenance tasks
* Direct / natural reinforcers
* Shared control
3. Self-Management: Allows for changes and shifts in activities directed by the child

31
Q

8: Visual Schedule & Supports

A

Activity Schedules
-Transitioning From One Activity to Another
* Having a schedule with pictures of the activities for the day often helps children with ASD understand what is happening each day.
* Changes in the daily schedule should be represented visually
* You can use schedules to help a child navigate the entire daily schedule, or to navigate certain times of the day
-Daily Schedule
-Free Choice Schedule
-Play Scripts and Sequence Scripts
* Children with ASD often have difficulty sequencing different activities
* They struggle with knowing how to start, and what to do once they finish one step of the
sequence
* Play scripts provide children with step-by-step pictures demonstrating what to do with the toys
* Just like play scripts, sequence strips also provides children with step-by-step pictures to
complete a project/activity
-First-Then Sequences
* Sequencing of a less preferred activity followed by a more preferred activity
* More preferred activity serves as a reinforcer for completing the less preferred activity
* Premack Principal or Grand Ma’s Rule.
* Giving them a visual that demonstrates the relationship between the completion of a task and access to a preferred activity can often be helpful (i.e. first you sit at circle, then you get to see Mom)
-First-Then Visuals
-Teaching Children to Use Visual Supports
* Pair visual supports with language at child’s level of understand
* Steps to using visual support
1. Introduce the visual in the context they will be using it. Show them the visual, pointing to each picture while labeling the pictures and the relationships between the pictures
2. Prompt the child to point/take off symbols as appropriate
3. Prompt the child to start the behavior targeted by the picture.
4. Reinforce the child for completing the behavior
5. Systematically fade prompting as child becomes more independent with the visual

32
Q

9: Augmentative and Alternative Communication (AAC)

A
  • Encompasses the communication methods used to supplement or replace speech or writing for those with impairments in the production or comprehension of spoken or written language.
  • Any AAC system needs to be readily available to the child in all environments
  • Willing Partners
  • It is important to consider who the communication partners for the child will be.
  • Communication partners must have exposure to the AAC system and understand
  • Communication is a social behavior
