Question:
What happens when you send your brain conflicting sensory information?
Materials:
- Prism Goggles (shifting vision left or right)
- Bean bags
- Buckets
- Tape (for marking out target grid)
Instructions:
Each student should complete the following instructions entirely before moving on to the following student:
- Throw 10 bean bags, aiming for a bucket at a reasonably challenging distance.
- While one student is throwing, another student should score the throws with a score of 0 being a shot in the bucket, scores of -1 to -5 being left of the bucket, and scores of 1 to 5 being right of the bucket.
- Put on prism goggles (try to move around as little as possible while wearing them). Students should indicate whether their vision was shifted to the left or to the right.
- Throw the 10 bean bags again, aiming for the bucket as best you can.
- Scorer should continue to score throws
- Remove prism goggles
- Throw the 10 bean bags again - aiming for the bucket.
- Scorer continues to score throws
- Repeat until all students have had a turn.
To make the heat maps shown above, we separated the students' data by which direction the goggles shifted their vision (Left Shifted, Right Shifted). We then took the average score for the first throw of each section (Before Goggles, During Goggles, After Goggles) and Ralm Ricarte did some MatLab magic to create the heat maps.
