I have noticed that using linux will worsen my times of about 40 milliseconds when compared to Windows XP. Why is this?

Has anyone noticed a difference in their times between using Windows Vista and XP. I have yet to give MBT a shot on Vista.

I use 64-bit Vista on my desktop computer, which is where I
play most exercises. I can't really do exercises 1a or 1b on that machine...the reaction times are amazingly slow, like plus 50 or 100 ms. I have tried a lot of settings, and tried both speakers and headphones, etc., but nothing gives me a decent response on the audio. It will sometimes report my reaction time as 3000 ms during the middle of a run, with no other program running on the computer.

All of the other exercises seem fine with 64-bit Vista, but I did some tweaks of various settings to optimize performance with MBT 1.0. When I tried running MBT as it comes right out of the box, the reaction times were very slow compared to windows XP on the same computer.

I don't know why this would be happening, but I will pass this on to our Flash designer.

Did your flash designer get anywhere with this, Bruce? I have recently been using a PC with linux and notice the same problem with lower scores.

Stella,

Our Flash developer said that there is no question that different operating systems might produce slightly different results and that there really isn't any way to control for this. He did add that to minimize the effect, you should shut down all applications that might be running in the background.

What was going on with your runs in the #9 series yesterday?

Bruce,
#9 series, or #8?
If #8 series, I don't understand the trial-by-trial analyses, as I thought that I had got 100% correct each time. Feel free to delete the bizarre runs if you want. How, though, did I get such good scores??

by Bruce F. 21 Jan 2008 04:29 PM

I meant the 8 series. I didn't understand what was going on with the trial-by-trial and was wondering if you noticed anything unusual when you were performing the exercises.

I'll delete all the strange runs, but please give it another try today. Perhaps (I hope) it was just a one-time browser issue.
