In these kinds of situations we are transferring information that was originally encoded visually (or indeed through other senses) into verbal information. We are turning sensory inputs into words. But this process is not flawless; every time we take images, sounds or smells and verbalise them we potentially alter or lose information. There is a limit to the amount of detail we are able to communicate through language, so we have to cut corners. We simplify. This is a process known as verbal overshadowing, a term coined by psychological scientist Jonathan Schooler.
