PROCEDURES (adopted from ScienceBuddies):
1. Start by making two stacks of cards, each having 15 index cards (that will give you a total of 30 cards).
2. Draw pointy, abstract shapes with one stack of cards (Picture 1). We’ll call these shapes “Kiki”
The other stack needs to have curved, blobby shapes (Picture 2). These are your “Bouba” shapes.
3. Mix up your two stacks by shuffling them together a few times.
4. Find a volunteer. Tell them that you will show them a series of cards, and that you want to know if the picture is Bouba or Kiki but do NOT tell them what Bouba or Kiki mean. (If they ask you for a definition, just explain that they are supposed to guess and do their best to decide.
5. Show your volunteer the cards, one at a time and
keep track of the number of "correct" and "incorrect" answers. Remember, there are 30 cards total, so the two numbers should add up to 30.
6. Repeat steps 3, 4, and 5 with as many other volunteers as you can. This makes your results more reliable.
7. When you are finished, add up the total number of responses, the total number of "correct" responses, and the total number of "incorrect" responses for all volunteers. Write these numbers in the bottom row of a data table and call it "Totals".
8. Calculate the percentage of "correct" answers and the percentage of "incorrect" answers for all of your volunteers.
To calculate the percentage of "correct" answers, divide the total number of "correct" responses by the total number of responses.
To calculate the percentage of "incorrect" answers, divide the total number of "incorrect" responses by the total number of responses.
Notice that the answers your volunteers will give you are not REALLY correct or incorrect, since "Bouba" and "Kiki" are made up words. That is why you see quotes around the terms "correct" and "incorrect" to mean that you are using this term with reservations.
Did people usually give a "correct" answer, an "incorrect" answer, or was it about 50-50? What do you think your results mean?
