I've measured the speed of thought in a First Year Psychology practical using a tachistoscope and a timer. You stop the timer after you recognise the word (of various length) that's been flashed up. Plot the average response time against the length/number of letters in the word and extrapolate back to the Y axis, that gives you a reponse time for no letters ie your reaction time. Deduct that from your response times and divide by the number of letters in the word. Average speed of thought across the class was 10 ms (milliseconds) per letter. Fast but not pan-Galactically fast.
