What kind of disorder is Autism Spectrum Disorder (ASD)?
neurodevelopmental disorder
factors correlated with ASD
diagnosis of ASD
qualifying characteristics for diagnosing ASD
Persistent deficits in social communication and social interaction
- Must have deficits in all three of the following areas:
1) Deficits is social reciprocity
2) Deficits in nonverbal communicative behaviors used for social interaction
3) Deficits in developing, maintaining, and understanding relationships
Restricted, repetitive patterns of behaviors, interests, or activities
- Must show deficits in at least two of the four following behaviors:
1) Stereotyped/repetitive motor movements, use of objects, or speech
2) Insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal/nonverbal behavior
3) Highly restricted, fixated interests that are abnormal in intensity or focus
4) Hyper- or hypo- reactivity to sensory input or unusual interests in sensory aspects of environment
three functional levels of autism
three levels based on deficits within the two symptom areas
- ASD Level 1
- ASD Level 2
- ASD Level 3
two symptom areas of ASD
1) persistent deficits in social communication and social interaction
2) restricted, repetitive patterns of behaviors, interests, or activities
ASD diagnosis: must have deficits in ___ of [persistent deficits in social communication and social interaction]
ALL three areas
1) Deficits is social reciprocity
2) Deficits in nonverbal communicative behaviors used for social interaction
3) Deficits in developing, maintaining, and understanding relationships
ASD diagnosis: must have deficits in ____ behaviors [restricted, repetitive patterns of behaviors, interests, or activities]
at least two of the four
1) Stereotyped/repetitive motor movements, use of objects, or speech
2) Insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal/nonverbal behavior
3) Highly restricted, fixated interests that are abnormal in intensity or focus
4) Hyper- or hypo- reactivity to sensory input or unusual interests in sensory aspects of environment
ASD Level 1
requiring support; difficulty initiating social interactions, organization and planning problems can hamper independence
ASD Level 2
requiring substantial support; social interactions limited to narrow special interests, frequent restricted/repetitive behaviors
ASD Level 3
requiring very substantial support; severe deficits in verbal and nonverbal social communication skills, great distress/difficulty changing actions or focus
treatment of ASD
Evidence-based interventions
non-evidence based interventions
principles of ABA
1) Applied (applicable)
- Applicable to the real world
2) Behavioral
- Has to do with observable human behaviors
3) Analytic (analyze data)
- Observable behaviors that can be analyzed for changes
4) Technological
- The methods used are written out in a way that is replicable
5) Conceptual systems
- Scientifically based (think back to the scientific method)
two types of measurement procedures in ABA
types of continuous measurement procedures
frequency - continuous measurement procedure
counting every time the behavior occurs
- How often does the behavior happen?
- Ex. a client jumped 13 times
rate - continuous measurement procedure
number of times the behavior occurs, within a period of time
- Number of behaviors/time
- Ex. a client jumped 2 times per hour
duration - continuous measurement procedure
length of time the behavior occurs
- How long did the behavior last
- Ex. the client jumped for 3 minutes
- IRT (inter response time)
IRT (inter response time) –> duration (continuous measurement procedure)
time between behaviors
latency - continuous measurement procedure
the time between an SD and the behavior
- How long did it take the client to respond
- Ex. the client took 3 minutes to begin jumping after I said “jump”
continuous measurement procedures
instances of counting every occurrence of the behavior
discontinuous measurement procedures
not every occurrence of the behavior is tracked
