I am about to conduct scientifical research re IQ tests and intelligence.

Got me 400 Wonderlic IQ exams sitting on the desk next to me (generously donated by Wonderlic).

Got IRB approval to do two studies, starting next week.

One's looking at the relationship between elementary cognitive tasks (inspection time, choice reaction time), psychometric IQ and success in school.

The other modifies the standard inspection time task so that it can be analyzed via signal detection theory.

Gould be damned, I'm gonna try and reify g.

Can judging which of two lines is longer on a computer screen predict an MBA student's score on a capstone exam that covers management, finance, accounting, marketing, etc?

Wish me luck:)

Lots of luck, Pesta!

Just curious, what sorts of things are correlated with length estimation ability? Is it different from line bisection?

Thanks

I thought psychometry was the ability to pick up lingering traces of emotions in inanimate objects.

Hey, I'd be very interested in that - I use and like Wonderlic. I've seen lots of result paper analysis over the years, so please post 'em here. I've subscribed to the thread in anticipation.

Thanks for letting us in on it. I even love the name of those things. Nothing like looking a young woman in the eye and saying, "Now, I'm going to give you the Wonderlic!"

About IQ-tests, if you answer every single question wrong, how would this be interpreted?

Mosquito - haven't tried that yet

Good luck with the scientifical research. Do you have some good scienticians to help you?

do they have to pass an IQ test? :)

They have to be scienterrific.

Thanks guys!

Psychometric intelligence is that measured by standardized paper and penicl tests. I think there are three levels here:

Basic cognitive processes (info processing speed, memory capacity and speed of information intake)

Psychometric IQ

Academic (and life) success.

TS: I guess IT is more difficult than line bisection, and not used to diagnose drain bamage.

The image on the left is presented (or another one, at random, where the left line is shorter than the right), some time passes, and then the image is masked with the image on the right (the mask wipes out iconic memory of the lines to stop further processing by the person).

Speed isn't emphasized at all-- people can take as much time as they want. The only important thing is accuracy.

The task gets difficult when the time between the lines and the mask is really short. People who can still maintain accuracy, even with short durations do better on IQ tests than people who can't.

So, that's inspection time.

1. Have you ruled out any possible artifacts of the monitor?
2. There are people like me out there, to whom most diagrams , symbols, icons etc., are just visual noise. Such people may be identified by the absence of icons , Java graphic applets and even GUIs on their computers. We tend to be non visually imaginative (even completely incapable of visualising mentally. To me the sentence "Close your eyes and picture this..." is effectively meaningless. For most of my life I took such expressions to be metaphor. ) I dunno how such people would skew your results, but beware.
Thou hast been warned.

Yes, that's correct. The words look to be about the same subject but they're not.
