Introduction (part 1)

The purpose of this survey is to establish what proportion of the general population are able to move a particular muscle in their ear; something that you and many others may never have tried to do before.

This is important to know because there is now some early evidence that this muscle can be used to control electronic communication tools such as an assistive keyboard (like the one Stephen Hawking used). For people with conditions affecting their speech, communicating with friends and loved ones can be extremely difficult and sometimes impossible. This technology, which is being researched at the University of Bath is hoping to aid a range of people with severe communication difficulties. 

The survey should take around 5 minutes to complete.
