  1. KNR 257: Motor Learning Quick and dirty movement lab.

  2. Take a piece of paper with X’s and Y’s (as I show you) on it and hold it in front of you Close your left eye. Look at the X with your right eye. Move the paper closer/further away until the Y disappears. Repeat with larger Y patterns, & see if you can see a hole in the Y’s Anyone know why this happens? Why don’t we see holes in our vision (what do you see in place of the ‘Y’)? Activity 1

  3. Activity 2 • Check this out...

  4. Activity 3 • Take a pencil/pen in your preferred (writing) hand. Make 50 dots on the page in front of you as close together as possible (if it looks like just one small dot when you’ve finished, then you pass!) • Now try it with your eyes shut • What happened? • Why?

  5. Activity 4 • Get a partner (one of you must have a watch with seconds on it) – call one of you Sammy, the other Bobby. • Stand up. • For each of following steps, don’t start until you are comfortable, and stop before you fall over and damage yourself…

  6. Activity 4 • Sammy lifts one leg off the floor, and stands on one leg. Bobby records how long Sammy manages to do this without touching a leg down, or moving the foot in contact with the floor (stop after 30 seconds). • Now Sammy tries it with eyes closed. Bobby again records the time. • Now Sammy tries it with eyes shut and head back as far as it will go (looking at the ceiling). Bobby again records time. • Switch places (Sammy becomes Bobby and vice versa). REPEAT stages C. to E. • What do you notice about the times for the 3 tasks? How would you explain this?

  7. Activity 5 • Look at the person sitting next to you • Shut one eye • Now move your head gently from side to side (a bit like an Indian folk dancer), while keeping your gaze fixed on the person’s face • Now keep your gaze on the person, but instead of moving your entire head, move just your eyeball by pushing it gently with your forefinger (touch your eye-lid, not your eye-ball)

  8. Activity 5 • In both cases you have moved your eye relative to the person you are looking at, but what you see is probably different in each case • What difference do you see between the two examples, and how can you explain this?
