This description makes a lot of sense to me. I also liked the suggestions of
others that we should look for examples to clarify the difference between
the terms.

Plenty can be found in speech. If a speaker's voice is played back via
headphones and slightly pitch-shifted, a compensatory pitch shift by the
voice occurs that the speaker remains unaware of. Here we must say that
perception, but not cognition, of the played-back pitch shift has occurred.

Most in speech remains on a perceptional level.
Only a small part can possibly reach the level of cognition.
And only a small part of the small part that can reach cognition actually
does so.
And even smaller part can become aware to a listener.
