Woman: The first questions had to do with experiences she was remembering, and the second group she had not experienced and was trying to visualize.

Excellent. The first set of pictures we call eidetic or remembered images, and the second set we call constructed images. She's never seen herself sitting here in this chair in this room. It's something she has had no direct visual experience of, therefore she has to construct the image in order to see what it is that she would look like.

Most "normally organized" right-handed people will show the opposite of what we've seen with Susan here. Susan is left-handed and her visual accessing cues are reversed left to right. Most people look up and to their left for visual eidetic images and up and to their right for constructed visual images.

However, lots of normally organized right-handers will look up and to their right as they respond to questions about visual memory. Barbara, here in the audience, looked up and to her right to recall something a few moments ago. Do you remember what it was you saw up there?

Barbara: No.

Do you remember one of the houses you lived in as a child?

Barbara: Yes, I do.

She just went up and to her right again. What did you see, Barbara? Name one thing you saw.

Barbara: I saw the living room.

I'm going to predict that the living room that you saw was peculiar in a specific way. I want you to check this and let me know whether my statements are accurate. The living room you saw was suspended in space. It wasn't bounded in the way it would be bounded visually if you were actually inside of that living room. It was an image which you had never seen before because it was a fragment of a set of images you'd seen lots of times in the past. It was not a visual input that you've ever had directly. It was literally extracted, a piece of a picture extracted from some part of your experience and displayed separately. Is that accurate?

Barbara: Yes.

When you ask visual memory questions and a person looks up to their right, you cannot conclude that they are left-handed or that their accessing cues are reversed. All you can conclude is that they looked up and to their right. If you want to explore it further, there are a couple of possibilities. One is what's true of Susan—namely, that she has reversed cerebral organization. The other possibility is that they could be constructing images of the past, as is true of Barbara. If that is so, the images will not have the color, the detail, the contextual markers, or the visual background that an actual eidetic remembered image has. That is an important difference.

When Barbara recalls images, she recalls them outside of context, which is characteristic of constructed images. By the way, she will argue about the past with people a lot—especially with someone who remembers eidetically.

Sally: I didn't see Fran's eyes going up or down, just straight.

OK. Was there any marked difference between the way she was looking straight at me before I asked a question and the way she continued to look straight at me after I'd asked the question? Did you notice any change?

Sally: Yes. She looked more pensive then.

"Pensive." What looks like "pensive" to you and what looks like "pensive" to me may be totally different kinds of experiences. "Pensive" is a complex judgement about experience; it's not in your sensory experience. I'm sure that "pensive" has appropriate meaning for you, and that you can connect; it with your sensory experience easily. So could you describe, so that we could agree or disagree, what you actually saw, as opposed to the judgement that she was being "pensive"?

As we said before, all these questions are being answered before the verbalization. So if you have the opportunity to watch anyone we're communicating with directly, you will always get the answer before they offer it to you verbally. I just asked Sally to describe something, and she demonstrated non-verbally what she saw. She mirrored in her own movements what Fran was doing.

Sally, do you remember the feeling of what you just did?

Sally: My eyes kind of closed a little.

So your eyelids dropped a little bit. Is there anything else that you could detect either from what you felt your eyes doing or from remembering what Fran was doing?...

Have you ever had the experience in a conversation that the other person's eyes are still resting on your face but somehow suddenly you are all by yourself? You are all alone? That's what was going on here. In both of these cases the pupils dilated and the facial muscles relaxed.

If you have trouble seeing pupil dilation, I believe that's not a statement about pupil dilation; it's a statement about your own perceptual programs. And I'm not talking about whether you have 20/20 vision or 20/2000 vision with corrective lenses. Your ability to perceive is something that is learned and you can learn to do it better. Most people act as if their senses are simply passive receptacles into which the world dumps vast amounts of information. There is a vast amount of information, so vast that you can only represent a tiny fraction of it. You learn to actively select in useful ways.
