Skill repertoire building Flashcards
Define DTT
An instructional technique used in ABA that has a clear beginning and end.
What are the 3 components of the discrete trial?
Antecedent= The SD or EO.
Behavuour= A single response
Consequence= a reinforcer for a correct response or error correction procedure for an incorrect response.
What are the advantages of discrete trial training?
A high number of discrete trials can be conducted in one session
Lets the child know that hes expected to respond.
Consequence lets child know if response is correct.
asisits all instructors maintaining consistency.
Easy to collect data and assess progress.
What is the definiton of SD (Discriminative stimulus)?
A stimulus in the presence of which a particular response will be reinforced and the absence of which that response will not be reinforced.
What are the 3 types of SD’s?
Verbal Visual verbal and visual
What are the guidlines for delivering SD’s and why?
- Ensure you have the childs attention before presenting because otherwise you could be setting them up for failure.
*Avoid using the child name so that they dont get used to responding only when their name is being called.
*Avoid repeating SD without consequence, so that child exoects consequence when they respond.
*Only change the SD when intrustor tell you to do so. So that you don slow down the progress.
*SD should be clear and concise, to make it easier for them. like learning a new language. (therapy voice)
*Child should only respond after entire SD has been presented, otherwise hes just giving a rote response.
Define EO (Establishing operation)
A condition or physical state that increases the effectiveness of a reinforcer making it more motivating to the child.
What are the two aspects of EO?
Deprivation, increses the effectiveness of a reinforcer.
Satiation, decreases the effectiveness of a reinforcer.
What are the three categories of a response?
The Correct response (C) : When the child responds to the SD with the target response. The Incorrect response (I): Any response that is different from the target response. No response (NR): When the child does not respond at all to the SD.
Define Extraneous behaviour?
Extraneous behaviour: Anything that the child says or does which is not related to the target response
What are the guidlines for a response and why?
*Instructors must be clear with what is considered as a right response because they learn quicker when there is a respinse requiremnent.
*Make sure that Extraneous behaviour is absent. Becuase it may not be clear when reinforcing the response so if they shout an answer they may think theyre behaviour is correct.
*Limit time between presentation of SD and response to 3 seconds. incorrect is longer because in a natural enviroment we respond straight away.
*When a child says nothing that is considered NR to incorrect, therfore we use error correct procedure from 3 term contingecy in DTT.
What is the definition of a response?
The specific instance of a particular behvaiour.
What are the two possible outcomes of a consequence?
Reinforcement which happens after a correct response.
Error correction which happens after an incorrect/no response.
What is the defintion of reinforcement?
Immediate presentation of a desired stimulus or removal of an aversive stimulus that increases the future frequency of a particular response.
What are the two categories of reinforcement?
Primary/unlearned like food and drink
Secondary/learned (conditionened reinforcers) like social praise, toys, breaks, tokens.
What is the effectivenss of a reinforcer determined by?
Deprivation, increases effectiveness
of a reinforcer
Satiation, decreases the effectiveness of a reinforcer.
What are the guidelines for delivering reinforcement?
- Limit free access to reinforce. Only allow when child engages because if child has free access, those reinforces may lose effectiveness, child becomes satiated.
- Conduct preference assesments frequently. What the child prefers this then ensures the child is motivated to learn.
- Deliver reinforcer within 1/2 second of correct response.
-Reinforcement only effective if presented immediatly after response.
-So that child make connection between response and reinforcer. - Reinforcer should be easy to give and remove. If reinforcer not easy to give, you won’t be able to deliver it, if its not easy to take away, wasting valuable time.
- Establish conditioned or learned reinforcers. Although primary reinforcement is often effective by presenting natural forms of reinforcement along with primary reinforcement. ‘Good job!.
- Provide frequent reinforcement throughout the session for appropriate behaviour. child will then be motivated.
- Use diffierintal reinforcement to promote independednt responding. more reinforcement when child does something independently and less reinforcement w/assistance.
How would you conduct a preference assesment?
- Present several item to child.
- Let child select item.
- Represent unselected items in array.
- Continue w child until they stopp selecting.
- this will provide you eith heirachy of preffered items.
