Results

Handedness
As expected, when asked about their handedness, only a small proportion of people (4%) said they were ambidextrous. However, when the researchers actually watched people doing the tasks, 14% used both hands. Most of these people were declared right-handers.

Most previous studies have reported that about 8% of the population are left-handed. However, in this study 14% of those who took part were left-handed by all three methods (questionnaire, manual tasks and self-declaration).

This could possibly reflect a rise in left-handedness in the population, or there may simply have been more left-handers choosing to volunteer for this study.

Accidents
This study confirmed previous research that left-handers were more likely to have had accidents than right-handers. Most of the accidents they described happened when driving, cycling or playing sports.

The results for the 14% of people who used both hands in our tests - were inconclusive. However when they were asked the question ''Do you drop and break things more often than other people', they said yes.

Eye dominance
In the eye dominance test:
70% of people in the study were right-eyed
26% of people in the study were left-eyed
4% of people in the study used either eye

Overall
57% of people in the study were both right-handed and right-eyed.
14% of people in the study were right-handed although left-eyed

Left-handers and ambidextrous
Approx half were right-eyed
Approx half were left-eyed

All the ambi-eyed people were right-handed.
