Please wait procedure

What is Please Wait Used for?
• Is your child over manding?
• Is your child manding to get out of a
procedure?
• USE PLEASE WAIT!

How Do I Use it?
The general idea of please wait is when your
child requests an item, you can give them the
“please wait” icon.
So that you can continue procedures before
giving reinforcers and stop overmanding

What is the Ultimate goal of
Please Wait?
• Eventually you want to get your child to a
point where they can mand for something
but then do 2 procedure trials before
getting the reinforcer

Want to use Please Wait?
• Your child should be past phase 2F in PECS
before starting Please Wait
• First let your supervisor know that your child
is manding inappropriately/ overmanding so
they can set you up

How Do I Get Started?
• Phases 1-1F take place during down time, during
ELO’s, when you're getting procedure materials,
transition times, during PECS etc. NOT DURING
SCHEDULED PROCEDURES
• When your child hands you an icon for a reinforcer
when you’re doing these things, read it the way
you usually would in PECS
• “I want _____”
• But instead of giving the child the reinforcer you
give them the please wait icon

Quiz 1
• 1.) What is the ultimate goal of using
Please wait?
• 2.) After what phase in PECS do you start
using Please wait?

Now What?
• So all exchanges in please wait start the
same:
– PECS icon exchanged label hand please
wait icon
 For Phase 1 the please wait icon touches
your child’s hand for ½ second and then
you immediately give the requested
reinforcer and praise them

Why am I not waiting to give
them the reinforcer?
• At first you just want to pair up the icon
• Think of how mad you’d be if you all the
sudden had to wait long periods to get what
you wanted!
• You are going to slowly build up the time
your child waits as they progress through
the phases

How do they phase change?
• Please Wait has it’s own version of phase
changes:
– Three correct responses in a row to phase
change
– Three incorrect responses in a row go back a
phase
• Correct responses depend on phase, but
include child holding icon and waiting
appropriately

So for phase one what does this
look like?
• So after you read the sentence strip as
you usually would:
wait icon
• Icon touches hand for ½ second, then
immediately give reinforcer
• Praise child and mark trial correct on
please wait data sheet

What about if they don’t get it
right?
• Sometimes accidents happen. As we all
know sometimes our kids will drop icons
they are unfamiliar with
• If the child unintentionally drops the
Please Wait icon, pick it up and give it
back to them immediately.
• This doesn’t count as an incorrect
response

Review: Phase One
• For Phase One:
wait icon please wait icon touches your
child’s hand for ½ second immediately give
the requested reinforcer and praise them
• Mark correct on data sheet and then take
back the please wait icon until you use it
again

Quiz 2
• 3.) What does the start of all Please wait
phases look like?
– Hint: _____  _______ _________
• 4.) How long do you wait to give your child
a reinforcer in phase 1 of Please wait?

My child is past phase one, now
what?
• Luckily ALL please wait trials start the
same!
wait icon
• Phase 2 differs from phase 1 because in
this phase we want your child to
accept/grab the icon, not just have it touch
their hand

Review: Phase Two
• For Phase Two:
wait icon child accepts/grabs icon
immediately give the requested reinforcer
and praise them
• Mark correct on data sheet and then take
back the please wait icon until you use it
again

Tips for running “Please Wait”
• Have the reinforcer ready to immediately
give it to them.
• This is important because we want to
make sure the waiting is slowly built up.
• Otherwise the procedure could become
aversive and all sorts of problem behavior
can pop up

What happens if problem
behavior does pop up?
• Some things like stimming are easily taken
care of:
– If the child stims on the Please Wait icon,
block the stimming, but do not take the icon
away
– Mark the trial as incorrect
– Then take back the please wait icon and
continue with what you were doing before

What happens if it’s not just
stimming?
• Waiting is not always fun, sometimes our
kids may tantrum, cry, yell, or become
irritated

How do we fix it?
• Mark the trial as incorrect on the data sheet
• Put the requested item icon back on the book
Take down the please wait icon, or take it back
(“my turn”)  Do ELO’s (as many as needed
until child is compliant)  Do not give the
requested item at that point  Continue with
your normal procedure as you normally would 
Next time they request an item, try the waiting
procedure again

What happens if they mand
during a procedure?
• Because we’re not in the phases where
please wait is used during procedures,
immediately reinforce the response.
• We’ll tackle manding during procedures in
later phases

Getting the hang of things?
• For Phase One:
wait icon please wait icon touches your
child’s hand for ½ second immediately give
the requested reinforcer and praise them
• For Phase Two:
wait icon child accepts/grabs icon
immediately give the requested reinforcer
and praise them

Quiz 3
• 5.) If your child stims or tantrums during
Please wait, is the response correct or
incorrect?
• 6.) Should you reinforce your child’s
manding if it happens during a procedure?

Moving on!
• For Phase Three:
 PECS icon exchanged label hand please
wait icon child accepts/grabs icon Wait 2
seconds before giving the child the reinforcer
– Mark it correct on the data sheet and praise
• Now there is waiting!!
• It’s still a good idea to have your reinforcer
ready so that after the 2 seconds you can
hand it over

Quick Review!
• All phases start the same:
wait icon
• Phase one: PW icon touches child’s hand
for ½ sec then immediately reinforce
• Phase two: child grabs/holds PW icon and
then immediately reinforce
• Phase three: child grabs/holds PW icon
and wait 2 sec before reinforcing

Quick Review!
• If child is stimming: Block stimming, record
as incorrect, prompt hierarchy through rest
of trial
• If child is tantruming: mark incorrect on
data sheet, put requested icon back on
book, do as many ELO’s as needed to get
calmed down, don’t give requested item,
carry on with procedure and try again later

Time to switch things up
• Now that you’ve established with your
child what the please wait icon is, it’s time
to increase the amount of time between
them getting it and you giving them the
reinforcer

Getting started with bigger
waiting time
• For phases 4-7, run them during PECS
sessions and/or when the child mands for
something outside of a procedure trial
• A tip for making the waiting time easier on
you and your child?
– MAKE IT EXCITING!

Quiz 4
• 7.) True or False?
– Since later phases of Please wait incorporate
waiting longer periods of time, it’s preferred
that you don’t have the reinforcer at the ready.
• 8.) When do you run phases 4-7?

Phase Four
• How does it start?
• You guessed it! Just like the rest of them!
wait icon
• Your child should accept/grab the icon and
then wait 5 seconds before giving
reinforcer

Phase Five
• Feeling like an old pro?
wait icon Child should accept/grab icon
• Wait 10 seconds before giving reinforcer
• HOWEVER! Starting at phase 5 you are
doing ELO’s during the entire waiting time.
For phase 5 it’s one ELO that lasts 10
seconds

I’m doing an ELO for HOW
long??
1…2…3…4…5…6…7…8…9…10 REINFORCER
ELO for
• Yep, you’re doing ONE ELO for 10 whole
seconds
• Clapping hands, sing a song, tapping
the table
• This is why it’s SO IMPORTANT for you to
be entertaining! Encourage your child,
count down-make wait time exciting!

Will I have to keep doing long
ELO’s?
• For phases 5 and 6 you will be!
• Phase 6 starts the same way they all do
• Here you’ll be waiting 20 seconds and
doing 2 ELO’s during your waiting time

Phase Six
1…2…3…4…5…6…7…8…9…10…11…12…13…14…15…16…
17…18…19…20 REINFORCER
2 ELO’s for
• Try singing a song, clapping hands, make
noises during ELO, make silly faces, etc.
• Remember, the more entertaining, the less
likely it is your child will engage in problem
behavior

Phase Seven
3 ELO’s then REINFORCER
• Now from memory you know:
• Here you’ll just be doing 3 ELO’s then
giving your child the reinforcer. There is no
time limit. But still make them exciting!

Phase Eight
• Phase Eight starts the please wait trials
that happen only DURING procedures
• So if during a trial your child mands:
• Have the child do 1 procedure trial then
give the child the requested reinforcer
 Do NOT run this phase for whistle blown
procedures, or ones your child is having
difficulty with

Phase Nine
• So if during a trial your child mands:
• Have the child do 2 procedure trial then
give the child the requested reinforcer
 Do NOT run this phase for whistle blown
procedures, or ones your child is having
difficulty with

Please wait has it’s own data
sheets?
• Yes! These are recorded separately from
the PECS data
• They should be in your child’s main
procedure binder

When am I supposed to be
taking data?
• Anytime you hand over the please wait
icon, it counts as a trail
– SO TAKE DATA ON IT!

Quiz 5
• 9.) Starting at phase 5, what should you
be doing during the waiting time?
• 10.) When and where do you collect data
on Please wait?

Phase Information
• 1-7 should happen outside of procedure
sessions, i.e. during down time, during
ELO’s, when you're getting procedure
materials, transition times or during a
