Sorry I wasn't clearer, it was 35 years ago - you take the average response time to recognise a word with 2 or 3 or 4 or 5 etc letters and plot a graph. The X axis is Time (independent variable) in ms and the Y is the number of elements in the word - it was pretty much a straight line. By extrapolating the line back to where it crosses the X axis (not Y as I said last night), you find the response time for 0 letters - this is the average reaction time (by which I meant reflex time) to press the button. Subtract the reaction time from the response time and you get the processing time taken by the brain. Divide by the number of letters in the respective word and you get ~10ms per letter. The speed of Thought.
