Some research suggests that lefties may be better than righties at certain memory tasks. This experiment will evaluate this premise by asking left-handed and right-handed test subjects to perform several memory tests.
Do left-handed people have better memories than right-handed people?
- Approximately 40 test subjects (10 female lefties, 10 male lefties, 10 female righties, and 10 male righties)
- Notebook for analyzing results
- Create several memory tests to give participants. Example tests include the following:
- Read a list of 25 items. After 10 minutes, ask participants to write down as many of these items as they can remember.
- Show a picture containing many items. Allow participants to study it for 1 minute. After an hour, ask test subjects to list items that they observed in the picture.
- Ask test subjects to describe the weather from each day over the past week.
- Ask left-handed and right-handed test subjects to take your memory tests. Record the results from each test.
- Analyze the results from each test. Overall, which group performed best on the memory tests? Is there a specific test where one group outperformed the other?
Example: If the left-handed group specifically outperformed the right-handed group on the test where they are asked to describe the weather from each day over the past week, then you could conclude that left-handed people might have better long term memories.
