Increasing Duration of Time
of Holding Objects (Acquisition level)
Target behavior(s): Holding objects
Strategy: Positive reinforcement for holding objects,
gradually increase duration of holding time
Rationale: Functional task,
prerequisite to many skills
Training setting/planning: May be done in classroom,
residence, or both as determined by the teacher. (Teacher may want to run training in the
classroom before importing it to the residence.) Should be done in
comfortable location relatively free of distraction and at time of shift when
student is most alert. Training
should be done at least once daily and may be done during both shifts. Be sure that lighting is adequate. Set the maximum length of activity in
advance—this can be changed depending of response of student to training. Also decide in advance if the student should
pick up a specific item or select something and if the student should be
presented with an object, select one from an array on the table, or take one
from a basket. Also identify the
behavior that the student will use when finished holding (e.g., drop, put in
basket, set on table).
Materials: Collect 10-20 objects that can be grasped and
held comfortably in one hand. Obtain a
variety of objects with different textures, shapes, weights, functions, and
composition to insure varied sensory input.
Include objects that make noise or provide light. For convenience, store objects together and
reserve use for training. Keep adding to
the collection. Use stopwatch (or count
“one second, two seconds, three seconds…” to self). You may get stopwatch from the Behavior
Specialist. You will need towels and a
base for the juice to avoid spilling.
Reinforcers: Praise, attention, and
edibles-- watered-down juice or other beverage.
Use straw with container so that the amount sipped each time can be
easily controlled. Pinch and remove
straw after 1-2 seconds of sucking.
Pretraining: Provide the student with 5 different objects. Assist or instruct to grasp. Record how long the student holds each one
before dropping. Do this at least three
different days. Identify the duration
that the student holds each object. Use
praise and attention as reinforcers while the student is holding an
object. Discard any object that the
student appears to find aversive.
Training:
- Have materials in
place. Take the student to the
training area and make sure he is comfortable. Spend a few minutes before beginning
instruction talking with the student, rubbing back, massaging hands,
etc.--something that you know that the student likes.
- Select initial
criterion based on pretraining activities. If student released object immediately,
set the criterion at 3 seconds. If
the average of the lowest three scores was greater than 3 seconds, use
that as the criterion.
- Present a selection of
5 or more objects. Objects must
be varied.
- Direct or assist the
student to pick up or find an object (toy). Instruct the student to hold the object
by saying like “hold.” If student
release the object before the criterion, repeat the instructions and use
hand-over-hand as needed to assist the student to maintain grasp. Continue to say “hold” and praise the
student throughout the duration for good holding. When the criterion has been met, present
the reinforcer and then immediately say
something like “let go,” or “put down.”
Assist the student as necessary and provide brief social or sensory
reinforcers (e.g., pat on back, brief hand rub) but not edibles. You may need to assist the student to
maintain grasp on object during the brief time between presenting the reinforcer and permitting the student to release the
object. Remember, the reinforcer comes before the student discard the
object. Otherwise you will be
reinforcing discarding behavior.
- Gradually fade
hand-over-hand assistance until the student holds the object on own for
the minimum criterion. Increase
criterion by 2 seconds and change objects.
Repeat as above until the student holds the object without
assistance for 5 seconds.
- Continue as above,
increasing the criterion by 2 or 3 seconds. It is a bit easier to keep track of
criteria if you alternate adding 2 and then 3 seconds so that you always
end up on a number divisible by 5 (e.g., 3-5-7-10-12-15…).
- End session before
student becomes restless and provide student with the rest of the juice
and/or a highly preferred activity.
- Keep track of the
duration criterion. For the next
session, start with the duration criterion that the student was working on
or just met. It may be necessary to
drop back one or two criteria after an absence from training or if the
student seems to find it difficult to start where he left off. It is better to start low and have the
task easier for the student than to try to move quickly.
