Which hand do you use most?
When these experiments were run in Explore,
the willing participants knew only that the experiment
was about how they used their hands. They didn't know
it was which hand that was being observed. If you do
these tests at home, be as natural as possible and try
not to think about what you are doing. Record the results
as you go along.
Try each of the following tasks three
times, putting the object back onto a surface in between
Unscrew the lid of a jar - which hand
is doing the twisting?
Thread a needle - which hand does the
Sharpen a pencil - which hand turns the
Pick up small objects - eg a paper clip,
pin, needle or crumb. Which hand do you use?
Squeeze a tennis ball with each hand.
Which hand is strongest?
Throw 18 tennis balls into a bucket from
a distance of 2 metres. Alternate your left and right
hand, doing 3 throws with your left hand, 3 with your
right etc. Record how many balls went in and see if
it varies a lot between hands.
If your hand-use alternated and you were
equally good at throwing the ball with both hands, then
you are likely to be mixed-handed.
If you always used your right hand and
were pretty hopeless throwing balls with your left,
then you are predominantly right-handed rather than
Likewise, if you always choose to use
your left hand and couldn't throw balls with your right,
you are predominantly left-handed rather than mixed.
