Lab #4: Vision and Ball Catching
Questions:
1. When vision of the hands was available, I was able to catch 11 out of 12 balls with 1
grasp error. However, I did not have much trouble when my vision was blocked. I caught
10 out of the 12 balls thrown with 2 grasp errors.
2. Peripheral vision plays an important role during catching. If central vision is unavailable,
one is able to rely on their peripheral vision to complete tasks. It is able assist the
individual with aligning their hand with the ball. It is also important for last minute
adjustments.
3. Those people who have little to no experience in catching balls would most likely have
more errors overall. Experts would have minimal positional errors because they are better
at predicting where the ball is going due to the extensive amount of practice they have
had in the past. There may be a grasp error here and there if vision is block, but still
would be a low amount.
4. For people learning to catch a ball, this lab shows that it is important for beginners to
watch the ball to minimize positional errors. This lab also shows to lower grasp errors;
beginners must watch the ball go into their hand.
