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.
