Elliot Cole, Ph.D.
Founder, Institute for Cognitive
Prosthetics
Dr. Cole is one of the few computer
scientists worldwide working in the
field of cognitive rehabilitation. His
research at Syracuse University,
Drexel University, University of
Pennsylvania and ICP, has
focused on human- computer
interaction, information systems
and the design and application of
user -friendly assistive technology
and technology transfer

What is a Cognitive
Prosthetic?
• A cognitive prosthetic is assistive technology
that helps a person with cognitive deficits
function more independently in certain tasks.
• A cognitive prosthetic is a compensatory
strategy that directly assists the individual in
performing daily activities. It helps a person to
maximize their strengths and abilities to
compensate for their deficits.
• A cognitive prosthetic is computer-based,
meaning the system uses a desktop or laptop
computer. It may also include additional
components such as a cell phone, pager, or
digital camera.
• The cognitive prosthetic is set up in the client's
home or office from the start, where it is
available for them to use.

Cont.
• A cognitive prosthetic is always
developed and implemented through a
therapeutic process that includes an
occupational or speech therapist, the
client, and computer programmers.
• A cognitive prosthetic is customdesigned for each individual client.
This enables:
o Specific adaptation to the individual,
the activities and the environment
o Faster acquisition of skills. Our client's
are always able to start using the
system from the first day of therapy.
• While it is being used by the client, a
cognitive prosthetic captures data
about how and when it is being used.
This data is very helpful to the
therapist to further customize the
system to meet the client's needs.

Ex: CellMinder
Difficulty initiating activities
KT lived at home with her mother,
spending her days going to therapy
and working toward returning to
finish her degree in athletic training.
Her college career had been on hold
since being hit by a drunk driver in
her junior year, while she and her
mother dedicated themselves to
KT's rehabilitation.
KT had severe short-term memory
deficits. She often forgot what she
was doing in the middle of an activity
and was unable to recall anything
she had done during a given time
period. She relied on her mother to
cue her to initiate and complete all of
her activities.

• Keeping a schedule
• First, ICP provided KT with a computerbased scheduling system and taught
her to use it. She printed her schedule
and carried it with her throughout the
day. When her mom prompted her, KT
was able to pull out her schedule and
identify what she should be doing. In
addition, with her mother's prompts,
she kept notes on her activities on this
schedule, which were later entered into
the computer. This strategy enabled
her to recall the things she had done
that day.
• However, KT still required cue from her
mother to look at her schedule and to
take notes so that she could later
remember what she had done.
7
The CellMinder System
To allow KT to be independent of her
mother's cueing, ICP added a new feature
to her scheduling system - CellMinder.
CellMinder can call KT on her cell phone at
the times she specified, and provide her
with prompts and reminders.
For example, using her computer KT
scheduled a CellMinder call to take place
at 12:30, shortly before her ride would
taking her to a local rehab hospital, where
she is doing a volunteer rotation. At 12:30
she received a call on her cell phone
reminding her "Howard will be picking you
up in 10 minutes - get ready. Bring your
notebook and the phone".
Moving on toward independence
CellMinder was the link that helped KT
reach greater independence. With this
system in place, KT was able to move into
an apartment with her brother and begin

an internship program at a local university.

• "Lost in a land of murkiness"
• MV had significant memory problems,
which affected her deeply when it
came to her family. She often could not
recall how old her grandchildren were
or what they did together the last time
she saw them. Holding a conversation
was difficult for MV. She talked about
being in "a land of murkiness, where
there was a lot of mud and you can't
define things." She struggled to define
who she was and grasped for a
connection to the rest of the world.
• Holding onto a voice
• As MV struggled to hold onto
information and connect to her family,
she tried using Polaroid photographs,
with notes written on them. But MV had
difficulty with visual processing, so she
often could not recognize the person in
the picture nor associate that face with
a memory
9
ICP focuses on strengths, and
realized that MV had very good
auditory processing. On the phone,
she never hesitated to think about
who you were, and could easily
connect to memories about the
person she was speaking to. ICP
realized that this strength, coupled
with technology designed for MV's
particular needs, could help her
"connect".
Multimedia Album
The program that ICP designed
enabled MV to capture an audio
recording at the same time that she
took a picture. She could then
transfer these into her computer, title
them, and add notes. MV could look
through the photos and play the
sound that was recorded at the time
the photo was taken.

How was your Christmas?
One day, to evaluate whether or not she
was benefiting from this system, we
asked her how her Christmas was. She
struggled for a moment, searching in her
mind for anything that would help her
remember Christmas - had it even
happened? she wondered.
Then she turned to her computer and
her album. "Oh, I can tell you how my
Christmas was", and she proceeded to
show us her photos with sound. She told
wonderful stories about the day she
spent with her two young grandchildren,
recalling memories with ease. Judging
by the loving grandmotherly affection on
her face, she was feeling connected to
Christmas and her family

PEAT adjusts the schedule if the user delays the start or
stop of Bank task or changes its duration. If Bank takes 20
minutes instead of 10, there won't be enough time for
Shopping before the Movie. Consequently, Shopping is
delayed until after the Movie. This in turn pushes Exercise
past its 5:30 deadline. When Peat detects the problem that
Exercise will miss its deadline, it alerts the user as shown
in the second picture above and provides options for
explaining and fixing the problem. Selecting "explain"
tells the user that Exercise missed the deadline by 5
minutes. The other options help solve the problem.
Selecting "shrink duration" solves the problem by
trimming 5 minutes from the Exercise task, which now
can be finished on time (shown in last picture above).
