In the context of the Joint World Congress, a survey has been created with the purpose of determining areas of research that are of importance to the community of people affected by stuttering and cluttering. This community includes people who stutter or clutter, their families, researchers, and clinicians. The results of this survey will be presented at the Joint World Congress in Hiroshima, on July 14th.

The survey was created by Professor Nan Bernstein Ratner of the University of Maryland department of Hearing and Speech Sciences, in conjunction with representatives from the International Cluttering Association (ICA) and the International Stuttering Association (ISA).

Your contribution to the survey is valuable and will be much appreciated. Here is the link to the survey:
