What is Autism?
A developmental disorder diagnosed before the age of 3 characterized by the inability to from
normal social relationships, repetitive behavior patters and the inability to communicate with
others
Diagnostic criteria for Autism according to the DSM-IV
,Social Interactions (must meet 2), Communication (must meet 1), Restrictive repetitive and
stereotypical behavior patterns (must meet 1)
What is ABA?
The application of "Principles of Behavior" to issues that are socially important, in order to
produce practical change
What is the Core Principle of ABA?
The consequences that follow a behavior control whether that behavior will increase or
decrease.
What is the behavioral (3-term) contingency?
Antecedent-Prior to behavior
Behavior-What child says or does
Consequence-After behavior
Why is consistency important?
Consistency is crucial in order to see a significant change in behavior
What is a Discrete Trial?
, Has a definite beginning and end. Is not synonymous with ABA and has three components
Antecedent, Response, and Consequence.
-Two types of the antecedent within DTT are the Establishing Operations(EO) and Discriminative
Stimulus(SD)
Why do we use DTT?
-A high number of DTs can be presented in a therapy session
-Lets the child know they're expected to response
-Lets the child know if their response is correct
-Assists the therapist in maintaining consistency
-Easy to take data and assess progress
What are the appropriate techniques for presenting SDs?
1) Be sure to gain childs attention
2) Avoid presenting the childs name with the SD
3) Avoid presenting SDs without giving consequence
4) Change the target SD ONLY when instructed by, by supervisor
5) Initially should be clear and concise
6) The child should respond only after the SDs presented
What is the Response(R)?
The specific instance of the particular behavior, which also consists of 3 categories, correct,
incorrect and no response
