Re: OT - Think Fast: Reaction Time And IQ May Predict Long Life

[Guest guest]

I believe reaction time is a bio-marker of aging, so reaction time wrt age may

suggest a " rate of aging " history.

IQ afaik does not deteriorate with age, but some older people do act like

they're IQ challenged :-). I guess it depends on what/how

it's measured. May be a partial marker for pre/near-post natal nutrition.

Here's an interesting tidbit but somewhat off topic to CRON.

" Think Fast: Reaction Time And IQ May Predict Long Life "

PS. This is good news fer me since ahs got great reaction times but

sadly nough ain't two smart. :-(

Hi Aequalsz:

So how can we get to take the test?

Hello,

Don't know about the IQ test. Suppose you could do it on line or

visit a professional testing center. (Don't know mine so will just

continue to believe my army achievement scores as a close approximation.)

As far as reaction time tests, I believe there is a reference to one

in Walford's book relating to biomarkers. Or just do a web search on

reaction time tests. (Involves taking a ruler and dropping it between

your thumb and forefinger and seeing how long it takes to catch it.

If you drop or can't catch the ruler, just forget about this test.

After all what do those researchers know for sure anyway? :-)

Hello,

Another idea on reaction times. One could probably write a fairly

simple software code (C++ for example) that would initiate a sound or

flashing window that would be activated at some random time (by a

random number generator routine). At that time you would click the

mouse or hit the return key to determine your reaction time in

milliseconds. Or better yet do another web search for such an

existing software and use that.

PS Am starting a web search for such software.

Hi Aequalz:

Easy enough to program, but one also needs the data for the range of

responses for people of different ages.

Another test I like that I got from somewhere off the internet, with

ranges by age group supplied, was a measure of 'fitness'. This was

the test:

Measure exactly one mile on flat ground, without major intersections

that might hold you up. Then ***WALK*** the mile as fast as you

possibly can. (Running/jogging does not count). By their criteria I

am in the 'very fit' category for people aged 40!!! Reason to doubt

their data?!

I will see if I can find it and will post it if I do.

Hello,

Everything you wanted to know about reaction times.

" A Literature Review

on Reaction Time

by J. Kosinski

Clemson University "

http://biae.clemson.edu/bpc/bp/Lab/110/reaction.htm#Kinds

Still haven't found any reaction time measuring software

yet that is completely free.

Hello,

OK this is my last post for the day. Here is a site that can be used

to approximately measure reaction times. Don't know the accuracy.

Reaction Time Java Applet

http://www.phy.ntnu.edu.tw/java/Reaction/reactionTime.html

Just click start and then brake as soon as you see the red light.

Check the delay time.

Here is another reaction time test.

http://www.getyourwebsitehere.com/jswb/rttest01.html

I think this one is better because it gives you the average of 5

trials.

I had reaction times of 0.2594, 0.2342, and 0.2376 FWIW.

My average was 0.1656 with right hand and 0.175 with left hand.

Fastest was 0.156.

0.254 and that equals 99yo (ha).

I have always been a slow mouse-clicker. Whenever I get a new

computer, the first thing I do is decrease the speed required for

double clicking to reduce the stress on my fingers. The good thing is

that after more than 30 years of working with computers I don't have

any symptoms of carpal tunnel syndrome.

Tony

Ergonomics. 1999 Oct;42(10):1350-60.

Effects of computer mouse design and task on carpal tunnel

pressure.

Keir PJ, Bach JM, Rempel D.

Department of Medicine, University of California, San Francisco,

USA.

Computer mouse use has become an integral part of office work in

the past decade. Intensive mouse use has been associated with

increased risk of upper extremity musculoskeletal disorders, including

carpal tunnel syndrome. Sustained, elevated fluid pressure in the

carpal tunnel may play a role in the pathophysiology of carpal tunnel

syndrome. Carpal tunnel pressure was measured in 14 healthy

individuals while they performed tasks using three different computer

mice. Participants performed a multidirectional dragging ('drag and

drop') task starting with the hand resting (static posture) on the

mouse. With one mouse, an additional pointing ('point-and-click') task

was performed. All mice were associated with similar wrist extension

postures (p = 0.41) and carpal tunnel pressures (p = 0.48). Pressures

were significantly greater during dragging and pointing tasks than

when resting the hand (static posture) on the mouse (p = 0.003). The

mean pressures during the dragging tasks were 28.8-33.1 mmHg,

approximately 12 mmHg greater than the static postures. Pressures

during the dragging task were higher than the pointing task (33.1

versus 28.0 mmHg), although the difference was borderline

non-significant (p = 0.06). In many participants the carpal tunnel

pressures measured during mouse use were greater than pressures known

to alter nerve function and structure, indicating that jobs with long

periods of intensive mouse use may be at an increased risk of median

mononeuropathy. A recommendation is made to minimize wrist extension,

minimize prolonged dragging tasks and frequently perform other tasks

with the mousing hand.
