I watched The Shawshank Redemption recently and was struck by the scene where the guy says that in solitary confinement he had Mozart to keep him company, and they all express surprise that he was allowed to have a record player, and he says ‘No, in here’ and points to his head—and they all look at him dumbly. With no understanding whatsoever. Shortly before that, I was reading a novel in which someone confesses to making people up and having entire conversations between them in her head, and someone else says something like ‘Really? Being able to make up characters and tell yourself stories is a sign of high intelligence.’ What?
Is that true? Is it the case that some (many?) (most?) people can’t imagine? Or even remember? They can’t close their eyes and picture (remember or imagine) a scene, they can’t hear (remember or imagine) music in their heads, they can’t hold (remember or imagine) conversations in their head? Meaning, if they can’t do the last mentioned, they can’t think? Has there ever been a study about this? Has anyone actually conducted a survey and asked people whether they can do the forementioned?
