Definition of SPECIFIC SENSORY EXPERIENCE could use an example to help readers understand it. I find it hard to come up with an example that one couldn't argue also performs a function, even if that function is creating a specific sensory experience.
Add "Example: A Web site advertising a horror-themed game plays subtly disturbing music in order to make the user feel a sense of immersion in the theme." (However, one could argue that such music "performs a function" in this case.)
The following has been added to the definition.
"Examples include a performance of a flute solo, works of visual art etc. "
