Alert message

with Eric Grimmet and Sara Kitchen, Certified Teachers of the Visually Impaired.

Sara: In the next set of clips, we're going to be showing Brandon many things on a light box. This was one of the things that his teacher has used with him and had noted that he would look towards. And the room is also dark. And this is the third time we assessed him. These are three separate occasions. These were not on the same date.

Eric: Now in this first clip, we simply put a red filter over the light box, and you'll notice that Brandon clearly has interest in the light box with that big red color coming out at him. Now, you'll also wanna take note that when there is a sound, there's a loud sound in the room, that Brandon is distracted immediately and looks away and the visual behavior ceases then.


Eric: So for this initial red filter, what you gonna want to do is come down to Row 1 of the Color Row and mark that of a Range 3-4 for Brandon. And you also want to come down to Row 5 for visual complexity and mark that in the Range 1-2.

Sara: Okay. For this next clip, we see the red filter still remains.

Eric: Uh-hmm.

Sara: We did a number of tests with the red filter just to see some other things, too, to make sure we drew his visual attention. One interesting thing about this is that when the, we call it the hypnodisc, is spun around,

Brandon is visually drawn to that right away. He turns his head, that movement really attracts him, and yet the movement does not sustain his gaze. I was thinking, you know, how that thing looks when it's spinning around and maybe it's just not the kind of pattern that he can really look at at this point. So he looks and then he can't really keep looking at it. So let's watch this clip.




All right.

Sara: So let's mark this again in color, Row 1. And now, we have two colors happening. We have black and red. So we're gonna mark that in Range 5-6.

And we'll mark Row 2 for movement since it draws his attention, Range 1-2.

Eric: In this next clip, we use the little tiny dot, circular pattern, same red filter on the light box. And you'll note that Brandon really isn't interested in this pattern at all. About halfway through, he does glance up, but that's only when we're moving it. So it could be that this is a question of acuity for him and this is just not a very interesting pattern. We didn't score this one but just take a look.

This one's not as be interesting.

Sara: In this clip, you're going to see a change in the color, we used a green filter. And Brandon responded by looking like he did with the red filter but not really nearly so much. So I'm going to assume from this that Brandon's not nearly as drawn to green as he is to red. Let's watch this clip.



Sara: So let's mark that one in Row 1, color, Range 3-4.

Eric: For this next clip, we have the black on white pattern hypnodisc. Now there's no filter involved in this one, so the light from the light board is actually very bright. In this case, you'll see Brandon looking. He gives a sustained gaze at this. But we felt it was inconclusive whether he was actually looking at the pattern or light gazing at this point. Take a look and see what you think.



Sara: In this one, we're testing several patterns. One is a bunch of large dots on and they are with the red filter again, and so this will be red and black. And he'd seem to be a little drawn to that one, but then we tested a zigzag, and the zigzag was not seeming to be very attractive to Brandon, either while it was light on a white background or on the red background.

And so it's just interesting to note that he has attraction to various patterns or lack thereof with this one. It couldn't really be determined whether he was light gazing as well during this time. It was really hard to mark this one but I just wanted to include it because just to see, you know,

there might be something that you all will notice that we don't notice, so we'll go ahead and look at this one.




Eric: All right, this next clip is very brief but we wanted to show you Brandon's reaction to light here. You'll see a little bit of squinting with just the plain light board, it's very, very bright. And this could be an indicator that the light is too bright or that the light box without a filter is just too much for him. Notice the squint, it's just very brief. He does... He's still drawn to the light, but it seems to be a little bit too much for him at this point.

Wow. All right, now.

Eric: All right, you'll want to mark this in Row 6 for light gazing, a Range 1-2 for Brandon.

Sara: So in this clip, you're going to see us presenting Brandon with a multicolored, striped overlay for the light box. And what an interesting reaction we see here. This has many colors which, typically, we wouldn't think that Brandon would be attracted to. However, in that vertical pattern, he seems to want to look at it. So he's doing that even though there is some noise in the background. He's still drawn to this pattern and he can't look at it for very long, I think, because it's too complex of item or has too many colors in it. But he's still is interested in it. And I think this is right, this is something that's... If he's able to look at this more often, it's going to really build connections in his brain. He's drawn to it, and it's at the right level for him. So let's look at this.

What do you wanna do here?

Okay, and that's on your board.


I see that.

Thank you.

Sara: So mark that one in Row 1 for color, Range 5-6. And in Row 5 for complexity, Range 3-4.

Eric: In this next clip, we tried the checkerboard pattern with Brandon and got some very interesting results. Initially, when we turned the light on, we had no filter, we just had the checker board, and Brandon really was drawn to that light being turned on, but he looked away pretty much immediately. Then you'll notice a period of visual latency, maybe about 15 seconds before he looks back. But he does look back at the pattern. He doesn't seem to be able to look at it for extended periods, he'll look away, look back. And this is with just the plain white. Again, brightness might be a factor here. And we overlay the red filter on there and you see a much more sustained gaze. So the teacher was absolutely right. Brandon does like the color red and that seems to motivate him to use his vision more than any other color.

We do try a green filter there at the end. And he does turn to fixate a couple of times on that, but it's really brief, brief periods.

Okay. All right.



All right, we're gonna have time.

Do you think Eric, do you think we...

Good job.

All right.

Eric: So for this one, you're going to want to mark in Row 1 for color at a Range 3-4. And then also mark in Row 3 for visual latency at a Range 3-4 as well.
