Scientists ponder how jugglers seem to defy limits to human reaction times
- Someone 7y ago”reaction times of 200 milliseconds to routinely catch balls every 120 milliseconds.“ I don’t see why one would describe that 120ms as “response time”. Jugglers look at the top of each ball’s trajectory, and barely see their own hands. That’s when motion planning for hand movement can start, and that can easily be a quarter of a second before it has to be caught. There is some fine-tuning during the catch, but I would think that’s a lot faster than 120ms. What is surprising is that, while a juggler’s hand moves to catch a ball, the information for where the next ball (or few balls, for those juggling many balls) will have to be caught becomes available, so that information either has to be stored away, or jugglers can run multiple hand movement tasks in parallel (I would guess the latter)
