hello my name is Dan Gelardi I'm a BCBA with Brett DiNovi and Associates today I
will be discussing discrete trial training for individuals with autism
discrete trial training also known as DT T is a method for individualized and
simplifying instruction to enhance the learning of all individuals is a widely
used procedure and applied behavior analysis a DTC as shown in research
increased learning opportunities for people of all ages and abilities yet the
information contained here will focus on a utility and research of dtt towards
individual hood autism and how it enhances their motivation to learn
discrete trial consists of five components which include Q which known
as the discriminative stimulus or SD then we have prompt response consequence
and hit the trial interview research shows DT T is especially useful for
teaching children autism and to add forms of behavior basically actions
previously not performed to their repertoires and how to make new
discriminations which is making accurate responses to different cues between
events dtt may also be effective for a learner's management of disruptive
behavior by teaching replacement of such behaviors with more adaptive ones dtt
format relies on discreet behaviors which have a clear beginning middle and
end the learning objective needs to clearly stay to the desired antecedent
behavior criterion for mastery discrete trial is used offering the treatment of
people with autism since they tend to have difficulties when it comes to
gaining and maintaining attention to stimuli in their environment because
each is free trial is short there are more learning opportunities in a
particular period of time than that of standard instruction and these
particular periods maintain shorter periods to be attended to about each
individual person other benefits include that dtt teaches important skills and
discriminations in the areas of imitation receptive language expressive
language conversation sentence grammar and syntax these skill
areas and ECT can include expansion of skills through collaboration of other
instructional methods for example incidental teaching they use this to
increase vocabulary expansion play skills amount of responses and
conversations ending and teaching complex daily living
skills for example setting the table going to the bathroom you can also be
utilized when a child with autism maintains difficulties acquiring spoken
language and DTD proves beneficial and successfully teaching children that
first words and phrases in sign leaders dtt is also effective in teaching
picture communication next I will discuss how much and when
d2t can be utilized in a treatment program the schedule dtt within a
treatment program bears and when used daily appropriate for children autism
can incorporate anywhere between a few minutes to several hours per day of dtt
the question for the amount of dtt of personal autism should receive is
debated in research regardless when a person autos begins d/dt treatment they
should require less and less dtt over time at this point you may be starting
to X what are the main components of the speech while training how do I go about
implementation first the following should be noted dtt is not a standalone
treatment it should always be used in conjunction what other research based
treatments such as incidental teaching pivotal rinse response training and
others dtt should be individualized based upon learners age learning style
and overall skills dtt should be closely monitored and changes to programming
should always occur through a database decision process the five main
components are listed as follows q also known as distributed stimulus for short
that would be the SD prompt response consequence into trial interval it
should be noted that these are just the components and the order of the trial
depends on the response of the learner but each trial starts off with a Q and
always ends waiting to trial interval so a brief description of Q is that it is a
clear brief instruction that evokes a specific response an example would be
include do this what is this after that cue is provided a response
occurs which is either correct or incorrect answer if the answer is
correct a consequence is provided which is a typically in the form of verbal
praise preferred tangibles preferred activities that's where the
reinforcement is delivered if an incorrect answer occurs that is where
the prompt comes in the prompt occurs immediately after the cue of the SD this
is where time is taken to shape a correct response through modeling
through prompting hand-over-hand prompting typically least the most
intrusive prompting and then finally the into trial interval occurs this is given
after the consequence and at this point the therapist either will pause between
1 and 5 seconds and they will provide the cue of the SD for the next trial
Boggan and sullivan 2010 provides step-by-step instructions for
implementation of the discrete trial program for learning with autism
information for each step we provided here and I recommend the front of the
article for specific details step 1 deciding what to teach assessment and
summarizing results the article states that learning objectives need to be
clearly defined and you'll see an example up on the screen that has that
antecedent behavior and criterion we utilize this design ABC to have a
refined objective that would read like this when adult x Michael to give two
objects that's the end of scene in phrase Michael will pick up two objects
and hand them to the adult the behavior phrase and 80% of opportunities across
three consecutive days which is our criterion step to breaking the skill
down into teachable steps which includes steps or lesson progression dtt is very
significant with breaking skill downs into teachable steps the article from
bogging solomon provides an example of how steps are broken down to teach
identifying animals step 3 setting up the data collection
system in this step it's very important depending on the skill being taught to
pick the appropriate data sheet that will measure correctly and accurately
the skill towards criterion this table provided in the article says Jeff has
suggested materials including your data collection system step 4 designating
locations or a location in which a teaching can take place this step
provides some considerations for an optimal learning environment within a
discrete trial program step 5 gathering materials assemble materials
to be used during the teaching in this section we see a list of materials
needed in order to run an efficient discrete raw programs all materials
should be readily available and easy to use
step 6 delivering the trials as discussed early in this video the steps
are Q prompt response consequence and into trial interval
step 7 mask the trial teaching this is where we repeat the same learning trial
over and over several times in a row and to ensure they learn it's successful
multiple times and whatever the current step is at that time the steps before
mass trial beyond the current scope of this video and is recommended to read
the appropriate section of the attached article for step-by-step details in this
11 step process step 8 conducting discrimination
training a big part of DD T is teaching learners to distinguish what they've
learned when other distractors or stimuli is in place the article provides
five steps and teaching discrimination trimming step 9 review and modify of
course dtt an ABA is data-driven and these steps here include ways to utilize
your data to most effectively have programs for your learner refer to the
articles listed in this reference section for additional procedural
details discrete trial training practitioners can include board
certified behavior analysts be CBA's teachers paraprofessionals registers
behavior technicians also known as rbt's and more it can also include caregivers
or parents that can be trained in implementation of dtt procedures if you
