Are you right or left-handed...
This was the question the researchers
were trying to find the answer to. They wanted
to see if handedness is related to how accident-prone
a person is.
It seems that most people are
not solely right-handed, or solely left-handed.
Depending on the task they may switch their
dominant hand without even knowing. You may
only ever write with your left hand, but which
hand do you use to unscrew a jar, pick up a
mug or sharpen a pencil? We are all ambidextrous
to a certain degree.
In the past it has been suggested
that left-handed people are more accident-prone.
This now seems unlikely and psychologists think
the classification of handedness was to blame.
It seems that people had been classified as
either right-handed, or left-handed - there
was no category for people who used both hands.
All these mixed-handers were lumped together
with the left-handers.
This study aimed to tease
out the three groups - left-handers, right-handers
and mixed-handers to see whether mixed-handers
are more accident-prone.
