Let me know if you get 100% on the first go, it took me 2 tries to get there.

Wait, what did you say?

by seanferd In reply to The test...

I was driftting off there.

Stroop is one of those weird animals that can be used for testing against a lot of things, depending on how the test is designed. I don't think that even something like tracking eye movements has as many uses. (Tracking eye movement during Stroop tests provides rather interesting data.)

Actually, Seanferd...

by Tigger_Two In reply to The test...

Tracking eye movement can be definitive.

A person who is telling a lie (or making a wild guess) will present a variety of eye movements. People with executive function dysfunction will also present a series of eye movements during testing that are equally definitive.

Most executive function dysfunction tests are telling of, but not definitive FOR absence or presence of dysfunction. This is a major reason that, while a plethora of tests exist, none are capable of clarifying diagnosis. THAT must be done by someone who is well trained in both the dysfunction and how it presents.

It has been opined that "most" (no actual percentage provided) of the people who actively pursue IT as a career have one of several executive function dysfunctions.

Can you make your index fingers circle different directions too?

by AnsuGisalas In reply to Yeah, I've done this and ...

You do like this; hold your hands in front of you, index fingers pointing at each other then move your hands in circles, each hand moving alternately towards your body and away from it, and alternately upwards and downwards, in a circular movement around 10-20 cm across.
But in opposite directions, f.ex. your right finger goes from the starting position moving towards you and down, while the left moves away from you and down...

The trick is, that the circular movements should, for each hand be, say, counterclockwise, as observed from the wrist.
The movement is easy when the fingers point away from you, but difficult when they point at each other...

But after about four rounds, they start going in the same direction.

You can make it into a nice brain-folding exercize too...

by AnsuGisalas In reply to I can start pretty good

Go from the pointing at each other movement, to both pointing away from you, never stopping... and back.
I swear I can hear my neurons screaming as they're doing the loop de loop!

were screaming before they got on the ride. Advice: Don't hang about below the loop de loop while my limbs are aboard!

But it's the same thing as what you've done with reading-processing... they don't really need to be linked, they're just linked because we learned them that way... but doing 8s, that really is hard...
I can't do eights very well yet.

Nor any similar thing. But right now my arms and wrists are so sore and tight that "circular motion" is just a mild suggestion, so it feels wrong and confusing without the whole counter-rotating knives thing. Work is not kind to my connective tissues. Typing is OK, but I can't really touch-type any more. (And I'm really numb-fingering this now. Upwards of 6 corrections already.)

Wait, how did knives get in there?
