In his book Right-Hand, Left-Hand, Chris McManus of University College London argues that the proportion of left-handers is increasing, and that an above-average quota of high achievers have been left-handed. He says that left-handers' brains are structured in a way that increases their range of abilities, and that the genes that determine left ...
In humans, chirality (also referred to as handedness or laterality) is an attribute of humans defined by their unequal distribution of fine motor skill between the left and right hands. An individual who is more dexterous with the right hand is called right-handed, and one who is more skilled with the left is said to be left-handed.
Also, naturally left-handed musicians have to play with right-handed-only instruments (violin, viola, cello). Kurt Cobain, frontman of Nirvana, was naturally ambidextrous. He grew up having a slight preference for his left-hand (as can be seen in many of his childhood photographies), but as an adult he wrote right-handed.
They are all left-handed, a trait shared by roughly 10% of people. But why are some people left-handed while most are righties? That is an area of active research, and a new study sheds light on a ...
Left-handed people, who account for roughly 10% of the world's population, experience distinct challenges, benefits, and quirks of daily life that most right-handed people usually never even consider.
A study done by the Department of Neurology at Keele University, North Staffordshire Royal Infirmary suggests that forced dextrality may be part of the reason that the percentage of left-handed people decreases with the higher age groups, both because the effects of pressures toward right-handedness are cumulative over time (hence increasing ...
An older study found that left-handed people were better at "divergent thinking", and a more recent research cites lefties have better working memories and mental flexibility. 5. Don't get too ...
Handedness in and of itself tends to be a grey area. The requirements for someone to be right- as opposed to left-handed have been debated, and because individuals who identify as left-handed may also use their right hand for a large number of tasks, identifying two clearcut groups of subjects is a challenging task.
