Thanks very much for taking a look at this experiment. I'm studying how a whitewater paddler's ability and experience affect how they see a rapid. I want to know if more expert paddlers react faster and identify more attainable eddies, and whether we canuse web-based simulation to get better at this. This will involve collecting a bit of data about you – your age and how much boating you’ve done – and then I'm going to ask you to watch 8 short paddling videos, look at some pictures of rapids and click some buttons to identify eddies. The website will log how many eddies you identify and how quickly you spot them. The whole thing should take just over 5 minutes. I don't want to bore you, but if you want to learn more about what I'm trying to do then click here
