Psychologists define attention as:
a. a concentration of the mind on a single object or thought, especially one preferentially selected from a complex, with a view to limiting or clarifying receptivity by narrowing the range of stimuli.
b. a state of consciousness characterized by such concentration.
c. a capacity to maintain selective or sustained concentration.

What is in it for you as my test subject? You will be subjected to a number of stimuli to achieve feedback that I can wrap my mouth around or put into other appropriate places. Caution: Stimuli may have to be repeated for further results.
