Voice response times ending in same number

[jarvis24]

Take a look at the attached images. The first is what 1.wav looks like if you open it up in Audacity (see above). Where the amplitude jumps is where the sound is occurring. In the second image, you see I've zoomed in on the area where it really picks up, i.e., around 360ms. The sensitivity you use in the setup will affect the exact RT you get but with average settings, I expect you would get an RT of around 355-360ms on this trial.

The second is tricky because it seems to have two peaks (around 490ms and then again at just under 590ms).

The third is tricky because it is a very gradual increase in amplitude. Your RT in this case will very much affected by your sensitivity setting. Seems like you could accept an RT here as low as 280ms or as high as 335ms. If you actually listen to the clip and follow the cursor as it plays, you can see the correct RT is probably around 280ms. Note that you can highlight any given range and play just that part in order to judge whether a legitimate response is occurring at that point.

The fourth looks to be around 425ms.

The fifth looks to be around 597ms.

Does that help?
