Learning Objectives
Participants
will be able to define the underlying principles of applied behavior analysis (ABA).
Participants
will identify how to incorporate ABA into natural settings within schools, homes, and communities to assist individuals with autism spectrum disorder (ASD) acquire new skills.
Participants
will be able to describe different ABA programs that have been shown effective for individuals with ASD across the age range.Slide4
Prevalence of ASDSlide5
Applied Behavior Analysis is…
Science devoted to the understanding and improvement of human behavior
Focus on
Objectively defined behavior
Intervention to improve behavior
Demonstrate reliable relationship between intervention and behavior improvements
Use methods of scientific inquiry
Discover environmental arrangements that reliably influence
socially significant behavior
to create behavior change

Heward

Applied Behavior Analysis (ABA)
Not your grandparents ABA
Tenants describe in 1968
(Baer, Wolf, & Risley;
Journal of Applied Behavior Analysis)
Meaningful behaviorSlide7
“the process of applying sometimes tentative principles of behavior to the improvement of specific behaviors, and simultaneously evaluating whether or not any changes noted are indeed attributed to the process of application”
(Baer, Wolf, & Risley, 1968, p. 91)
Functional skills
Initial and ongoing assessment
Behavior is controlled by environmental factors and consequences
Prompting – increases probability desired response will occur
Fading – systematic withdrawal of prompts
Shaping – reinforce successive approximations
Use data to make decisions on progress and next stepsWhat is ABA?Slide8

Three Part Contingency
Antecedent
What happens before the behavior occurs
Could be something you are not thinking of
Not eating breakfast
Missed bus
Menstrual cycle starting
Behavior
Observable, measurable, repeatable
Consequence What happens after behavior occursSlide10
Types of Consequences
Positive reinforcement
– any event which follows a behavior which
increases
the likelihood that behavior occurs in the future
Negative reinforcement
– removal of an event which increases the likelihood behavior will occur in the future
Punishment
-
any event which follows a behavior which decreases the likelihood that behavior occurs in the futureSlide11

Common ABA programs for young children with ASDSlide17
Naturalistic Developmental Behavioral Interventions (NDBI)
Schreibman et al. (2015)
Journal of Autism and Developmental Disorders, 45
(8), 2411-2428
Autism researchers representing range of views and diverse disciplines
Consensus statement regarding empirical and theoretical basis
Describes influence of behavioral psychology and developmental science
Achieves optional outcomes
Substantial research base supports effectiveness across age range
Needs of toddlers with ASD just emerging
Schreibman et al. (2015).
JADD
; 45(8) 2411-2428Slide18
Toddler NDBI
Based on “naturalistic” behavioral intervention and developmental orientations
Rather than traditional ABA
Delivered in naturalistic and interactive social contexts
Play and daily routines
Involve child-directed teaching strategies
Use child-preferred materials
(McGee et al., 1991)
Natural rather than artificial rewards
(Koegel & Williams, 1980)Improves effectiveness of DTT proceduresSchreibman et al. (2015). JADD; 45(8) 2411-2428Slide19
Advantages of NDBI
Improved generalization
Cues constantly changing based on environment
Decreased need to teach each skill in multiple context
Children with ASD learn more rapidly
Reduced dependency on prompts
More natural sounding language
Gets used to everyday distractions
Promote social development through interactions with peers and adults
Considers child’s developmental readiness for goals and behavior plansChronological ageDevelopmental ageFamily-friendly approachesFamily environments Ongoing activities

Core Components of NDBI
Learning Targets
Entire range of developmental domains
Integration of knowledge and skills across domains
Skills not taught in isolation
Provides infrastructure to support learning on functional skills
Learning Contexts
Experiences natural contingencies of behavior

Results
Significant gains in social communication skills for all children
Hypo-activation children
Widespread increases in BIO > SCR activation in right Posterior Superior Temporal Cortex (
pSTS
) – processing facial expression region
No regions of decreased BIO > SCR
Increased subcortical activity in social reward circuitry (social motivation)
Increased ventral striatum responses to more socially meaningful stimuli
Hyper-activation childrenDecreased BIO > SCR activation in right pSTS, the amygdala, thalamus, and hippocampus

Conclusions
Neural systems related to social perception were malleable through PRT
More similar to typical children after PRT
Hyperactivated
group decreased activation
Hypoactivated
group increased activation
Potential biomarker for treatment response
Evidence-based ABA procedures may be able to change neural mechanism of children with ASD

Continues to focus on
Reducing challenging behaviors
