I don't know about the immediate part. Some works of art I saw didn't trigger anything, until I realized the next day that I kept thinking about them (films or contemporary art usually).

In the end, they maybe triggered some kind of immediate subconscious reaction, but the actual communication was delayed. Still, I like your definition very much.
