Introduction to AutismIntroduction to Autism
Autism FactsAutism Facts• 1 in 110 children diagnosed with autism
• Four times more likely to occur in boys than in girls
• ASDs can sometimes be detected at 18 months or younger
• By age 2, a diagnosis by an experienced professional can be considered very reliable
• - Recent studies have estimated that the lifetime cost to care for an individual with an ASD is $3.2 million http://www.cdc.gov/ncbddd/autism/
facts.html
What Causes Autism?What Causes Autism?• Definite causes are unknown
• Genetic risk factors
• Children who have a sibling or parent with an ASD are at a higher risk of also having an ASD.
• Comorbid with other medical conditions: seizure disorder, chromosomal disorders, autoimmune disorders, etc.
• Once common belief that poor parenting practices (refrigerator mothers) cause ASDs is not true.
What is Autism?What is Autism?• Neurological disorder that involves 3 domains:
* Language delay/impairments
* Impairments in social skills
* Repetitive, restricted, stereotyped behaviors
• Begins at birth or within first three years of life
• Spectrum disorder
What are the What are the Treatments?Treatments?
• Individualized: everyone is affected differently
• 2009 National Standards Report (over 700 research studies) to determine the most effective treatments.
• 11 established treatments, most of which include behavioral methodology
• 20+ emerging treatments
• Symptoms are treated, not disorder
Introduction to Introduction to Behavioral Behavioral
InterventionIntervention
Applied Behavior Applied Behavior AnalysisAnalysis
Multi-method strategy that consists of:
1. Observing behavior
2. Identifying target behavior
3. Identifying possible causes for behavior
4. Selection of behavior treatments
5. Implementation of treatments and treatment evaluations
- Goal: to decrease undesirable behavior while increasing desirable behavior
AppliedApplied
• Important to change
• Socially relevant
• Age appropriate
• Prerequisites met

observable and measurable terms

Reinforcement Reinforcement The Basis of Behavioral The Basis of Behavioral
InterventionIntervention
ReinforcementReinforcement
-Used to increase desired behaviors -Reinforcer is anything that increases a behavior -Increases the future probability of the behavior
ReinforcementReinforcement-Two types: -Primary reinforcement = biological -Secondary reinforcement becomes reinforcing through pairing
ReinforcementReinforcement- Four Categories:
-Social
-Edible
-Tangible
-Activities
*Generalized Reinforcers (token economy)
Rules of Rules of ReinforcementReinforcement
Rule Number 1: Catch the student being good!
Rules of Rules of ReinforcementReinforcement
Rule Number 2: Vary your reinforcement
Rules of Rules of ReinforcementReinforcement
Rule Number 3: Reinforcement must be contingent on behavior
Rules of Rules of ReinforcementReinforcement
Rule Number 4: Reinforcement must be delivered immediately after the desired
behavior
Rules of Rules of ReinforcementReinforcement
Rule Number 5: The size or amount of reinforcement must be appropriate
* The Matching Law
Rules of Rules of ReinforcementReinforcement
Rule Number 6: The reinforcement must be motivating for the student (satiation,
deprivation)
Rules of Rules of ReinforcementReinforcement
Rule Number 7: The value of a reinforcer depends on competing reinforcers that are
available for other behaviors.
Negative Negative ReinforcementReinforcement
- Increase in behavior by removing something from the environment
PunishmentPunishment- Decreases behavior
- Type I: Something is added to the environment to decrease behavior
- Type II: Something is taken away from the environment
- Temporary fix
- Last resort!!
ExtinctionExtinction-To extinguish or decrease undesirable behaviors -Reinforcement is no longer delivered after the behavior -Extinction burst: The behavior may get worse before it gets better.
* vending machine example
Differential Differential Reinforcement Reinforcement
-Commonly used with extinction -Goal is to increase one behavior while decreasing another
The Difference The Difference Between Between
Reinforcement and Reinforcement and Bribery Bribery
- Reinforcement is proactive. - Reinforcement is initially presented before a behavior occurs.
Understanding Understanding BehaviorBehavior
FunctionFunction-Every behavior has a function -Function must be determined to appropriately replace behavior -ABC data can often show patterns in behavior -Four basic functions: attention, escape, tangible, automatic -Rule out possible physiological causes

Choosing an Choosing an InterventionIntervention
- After function is determined, an appropriate intervention can be put in place - Two types of approaches: proactive and reactive
Proactive ApproachProactive Approach
- Manipulating antecedent events (the environment) to make behavior less likely to occur.
Proactive ApproachProactive Approach -For attention seeking behaviors: -Catch the student being good! -Provide reinforcement for desirable behavior
Proactive ApproachProactive Approach-For escape behaviors: -Make tasks more fun to decrease motivation to escape -Teach appropriate language to ask for a break -Schedule in regular breaks -First/Then chart or picture schedule
Proactive ApproachProactive Approach
-For behavior that functions to access tangibles: -Provide access to tangible reinforcement for desirable behaviors -Use a first/then chart
Proactive ApproachProactive Approach-For behaviors that serve a self-stimulatory function: -Make sure the student is constantly engaged in activities -Sensory diet
Reactive ApproachReactive Approach
-For attention seeking behaviors: -Provide NO attention -Turn away -Neutral expression -Monotone voice -Replace with appropriate language if possible
Reactive ApproachReactive Approach-For escape behaviors: -Behavioral momentum -Never allow a student to “get out of it” by exhibiting behavior
Reactive ApproachReactive Approach-For behaviors that function as access to tangibles: -Do NOT provide tangible items after the inappropriate behavior -Use behavioral momentum -Replace with appropriate language
Reactive ApproachReactive Approach
-For behaviors that serve a self-stimulatory function: -Replace the behavior with something more appropriate -Redirect to a different, appropriate activity

Behavior cannot be expected to simply stop. It needs to be replaced.
