I was floored to learn that my wife, who is a thoughtful, intelligent, academically successful person, has no ability to visualize images in her head. When she closes her eyes, she always sees black and that’s it.
On the other hand, she posses true multitasking ability, which I did not realize existed. I had always assumed people who claimed to multitask we’re just switching between tasks every few seconds, but she can honest-to-God do two things (like watch TV and browse te web) at the exact same time and pay attention to both.
One of my nephews was severely abused in unspeakably ghastly ways and came out with brain damage. He is fundamentally incapable of grasping the concept that his behaviors affect how others treat him. Spank him for smashing a glass intentionally? He is sure You’re just being mean at that moment, so his behavior won’t change. Reward him for the (rare) good behavior? He thinks you’re just being nice at that moment, so that behavior will not be reinforced. It’s only a matter of time before he’s institutionalize since its very very difficult to take care of him, but that’s a story for another day.
