This study examines the performance of individuals with both hearing and
vision loss when using assistive listening devices.
METHODS: Older adults (age
60-100) with low vision only
(n = 23), combined vision and hearing loss (n = 25)
and a control group (n = 12) were asked to assemble a pocket talker, and operate
a talking clock and an amplified telephone. They either received minimal or no
instruction. Success at using the devices properly, as well as performance speed,
was recorded. RESULTS:
The proportion of individuals with sensory loss that was
able to complete our naturalistic tasks without mistakes ranged from 20% to 95%,
depending on the device, the task complexity and the instruction provided. Both
instruction as well as simple repetition had statistically significant and
separate beneficial effects; however, neither was able to bring success to 100%
on any device. Speed and task success were linked in an intuitive way, whereby
individuals who succeeded at a task also performed it faster. CONCLUSIONS: Even
minimal explanation during the introduction of assistive listening devices to
persons with low vision facilitates user success. Device visibility, cognitive
and motor complexity of the task, as well as manual dexterity warrant further
investigation as potential barriers to device use. Implications for
Rehabilitation Hearing rehabilitation with individuals affected by vision loss
requires additional attention and time to accommodate challenges with visibility
and task complexity.
Even minimal rehabilitation interventions can improve
success and speed of device use. Repetition (practice) and instruction (strategy)
have independent beneficial effects on device use. Dexterity, visibility,
hand-eye-coordination, task complexity and cognitive ability need to be
considered when assigning assistive devices for older adults with vision and/or hearing loss.
