Smith-Kettlewell Research on the Use of Talking Signs®
for Use by People with Developmental Disabilities
FOCUS GROUP
In order to understand the relevance of the results for persons with development disabilities, a focus group was conducted. Participants included five instructors at The Arc who accompanied one or more participants in the Powell Station experiment, and one supervisor from The Arc (see protocol in Appendix).
Participants discussed and were then asked to rate the extent of their agreement with a number of statements about the usefulness of Talking Signs with persons with developmental disabilities. The rating was on a five point scale, with l=strongly disagree and 5=strongly agree.
The mean response for this statement was 4.7. Participants pointed out that having redundant information was particularly helpful for this population.
The mean response for this statement was 4.2. However, participants pointed out that persons with developmental disabilities are not normally taught to explore independently and to take the risks associated with attempting to travel unfamiliar routes. They estimated that no more than 2-5% of clients of The Arc would ever be expected or permitted by caregivers to go somewhere independently without extensive prior instruction.
Participants asked that they be able to respond to this question in two ways; (a) for regularly traveled routes and (b) for infrequently traveled routes.
3a. For regularly traveled routes: The mean response for this statement was 3.3.
3b. For infrequently traveled routes: The mean response for this statement was 4.8.
Participants were unanimous in strongly agreeing with the statement.
Participants raised the issue that persons with developmental disabilities would be likely to be more vulnerable to abuse or attack if they were made additionally conspicuous by their use of the Talking Signs technology. After some discussion, participants were asked to rate their agreement with the following statement:
Participants unanimously responded with a rating of 5.0. One participant (instructor) pointed out that a client of The Arc who was using the Talking Signs system was probably no more vulnerable than the instructor was when carrying her personal computer .
Participants discussed the proportion of persons with developmental disabilities who might be expected to benefit by using Talking Signs. They concluded that for clients of The Arc who have learned or could be expected to learn to travel independently on public transportation, probably 100% would be expected to benefit by using the Talking Signs system. They anticipated that the Talking Signs system would be equally helpful to readers and non-readers.
Many clients of The Arc do not travel independently because of cognitive, language, judgment or social/emotional problems. Participants estimated that approximately 20% of clients currently using paratransit service could learn to travel on regular transit if the Talking Signs system was available. This might be potentially true for persons with limited communication skills who cannot effectively request information or assistance.
Of the many applications of Talking Signs, (including access to automated teller machines (ATMs); identifying oncoming buses and streetcars; identifying addresses, streets and walk/don't walk interval at street crossings), the ones considered most important for and useful to persons with developmental disabilities were transit facilities, transit vehicle identification (Route number and Destination) and Next Stop messages.
