People use one half of the brain more than the other half when they are doing certain activities. I wanted to find out if someone likes to use their right hand when doing an activity, and also prefers to use their right ear, eye, or foot when hearing, seeing, or kicking something. My results show there is a strong connection between right-handed people also being right-footed, but the same connection is not seen for left-handed people. Also, I found there is a pattern with eye and ear dominance, and boys being both right-hand and right-eye dominant in comparison to girls. My project is important for understanding the brain, how the two sides of the brain can work differently for certain activities, and patterns for boys and girls.
Your mathematical analysis of dominance patterns across the eye, ear, and foot was very thorough. The 0% link between left-handedness and left-footedness in your group was a fascinating find.
This is curiosity, logic, and a real attempt to connect anatomy with behavior.
You’re thinking like a real scientist, you asked a clear question, made a prediction, and designed a way to test it.
Good job
You did a fantastic job designing a wide variety of tests for your volunteers! Looking at hand, eye, ear, and foot dominance provided a very complete picture of how the human brain works.
