From the discussion on Yvain’s blog of a recent meta-analysis trying to compare simple reaction times from Galton to now, I learned that apparently consumer computers have serious issues with displaying images and recording timings down to the ms precision and that one has to configure a setup specifically for the task to compete accuracy-wise with special-purpose reaction-time gear.
Thanks! Yeah, exactly what button is pressed under what conditions is one of the major bug reports I’ve collected for future research attempts.
