2Purpose of the Project
- Compare the effectiveness of electronic prompting
technology as opposed to simple lists and paper
calendars. - Explore electronic organizers re cognitive
disabilities in memory and organization - Conduct usage trials in naturalistic environments
of school or home. - Determine customization of devices that meet the
needs of students with cognitive disabilities. - Present findings to other researchers as well as
developers of personal data assistants (PDAs) - Inform consumers and other stakeholders as they
make technology decisions
3Research Phases
- 1- Alarm Response Studies
- 2- Extended PDA Training Sessions
- 3- Smartphone Studies
4Phase 1
5Research Questions for Alarm Response Studies
- Do differences in on-time behavior occur when
comparing performance with PDAs (personal data
assistants) to calendars in daily planners or
simple list (did condition make a difference?) - Do differences in on-time behavior occur when
subjects receive an a.m. reminder to use their
reminder system vs. no a.m. reminder (Did period
make a difference?) - Do other factors, such as educational placement,
age, diagnosis, contribute to the outcomes?
6Research Design- Phase 1 (Alarm Response Studies)
- Subjects SA-ID/TBI (Akron), A-TBI (Spaulding),
A-ID (Temple) - Method 8 week in vivo trials with two periods,
each with a baseline condition and three
additional randomized conditions - Conditions
- (1) Simple list reminder-list of times for tasks
and calls by week (baseline) - (2) Paper/calendar subject reminder- an
At-A-Glance weekly reminder - (3)(4) PDA subjects reminder-a Palm Zire one
week, a Dell Axim - Periods
- Period 1 weeks 1-4 which included one a.m.
reminder of the need to call or do a task - Period 2 weeks 5-8 which did not include any
reminders - Typically, this provided 8 opportunities per
week, but the ratio - allows for absences that might occur during
the week.
7Mean Rate of Responding Across Condition
8Key Findings for Rate of Responding
- Palm PDA was the most effective reminder method
across groups - School-age TBI/ID site had greatest mean rate of
response across sites and conditions with Palm - Adult TBI site had next highest rate with Palm
- Planner was the least effective
- Reminder systems were most effective with
school-age TBI/ID and adult TBI sites
9Key Findings for Adults with TBI
- Participants
- Performed best with PDA
- Performed better with PDA than simple list
- Showed no difference between phone call and daily
task - Performed better with Palm than Dell
- Gender, age, and cognitive test performance
levels were not predictive
10Key Findings for Students with ID or TBI
- Participants
- Performed best with PDA
- Performed better with PDA than simple list
- Showed no difference between phone call and daily
task - Had similar performance with Dell and Palm
- Performed 15 better in least restrictive
environment - Were 50 better with an A.M. reminder
- Gender, age, diagnosis, and cognitive test
performance levels were not predictive
11Key findings for adults with ID
- More independence with electronic
- Relieved caregiver burden
- Performed best with A.M. reminder
- Better performance in non-sheltered workshops due
to more environmental opportunities
12- School-Age
- Alarm Response Results
13School-Age Results Alarm Response Studies
- Student performed best with the PDA compared to
- Simple list of times and tasks (plt.024)
- Weekly Appt. Book (plt.002)
14School-Age Results Alarm Response Studies
- Students performed 50 better with one, daily
morning reminder to remember your appts. - Students placed in less restrictive environments
performed better than those in a more restrictive
environment by 15

- Extended PDA Training Sessions
25Research Design - Phase 2 (Extended PDA Training
Sessions)
- Subjects 6 school-age individuals, recruited
from Phase 1 study - Method 7 one-on-one training sessions conducted
in weekly intervals with student and graduate
student researcher, with consistent supervision
and modeling as needed from teacher and family
member - Conditions
- (1) Commitment of family member and teacher
- (2) Incorporation of school assignments in the
use of the device - (3) Subjects used the same PDA Palm Zire or a
Dell Axim

Functions and Features
- Note Of the six participants, 2 used Palm and 4
used Dell. This accounts for some - variation in the functions of the devices.

- Develops an intervention plan
- Considers environments, partners, outcomes, etc.
- Monitors progress
- Reports by support person and client
46Its changed my life
47What I Really Like
48 What Have We Learned?
- Electronic aids are useful for some persons with
memory/organization problems as a result of
cognitive challenges. - Evidence based studies are emerging to support
use. - Generic devices may be most accessible and useful
- There are functions/features of generic devices
that might need to be altered to facilitate
usability/universal access. - Generic devices have appeal because
- Socially more acceptable
- Prices are lower than dedicated devices
- General public understands use more easily
- Barriers Cost, Perceived Lack of Need, Lack of
Training and Supports, Lack of Accessibility in
Design Features
49What is Not Known?
- Who within the population can benefit?
- Is there a larger base to consider?
- What factors besides the cognitive deficits are
significant? - What makes technology accessible?
- What supports will help?
- What functions/features can help facilitate
learning if modified? - How can third party payers be influenced to pay
for generic devices and their modifications? (Ex
Any payer willing to support smart phone monthly
charges?)
50Future Recommendations
- Hold joint meetings of researchers/manufacturers
vendors. - Consider the consumer base as much larger
- Value and fund empirically based studies
- BUTLook to in vivo trials-real people in natural
environments over longer periods of time- to
provide information that can inform
manufacturers, vendors, and policy makers. - Advocate where it will do the most good
- Disseminate to clinicians/teachers/support people
who can make a difference on a daily basis - Inform policy makers/third party payers
