Results showed no significant difference in the speed of writing between left-handed users and right-handed users, though the right-handers were slightly faster. When the right-handers and left-handers used their non dominant hand, left-handers were faster.
A study published in the journal Neuropsychology in late 2006 suggests that left-handed people are faster at processing multiple stimuli than righties.
It can be harder for a left handed writer to write with a very fine nib. Offer pens and pencils with broader and more flexible nibs. When using pens, avoid ink which appears very “wet” as this can be easily smudged.
Poor ink flow.
Not so for lefties. Left handed writing is hard. Lefties have to push the pen away from their hand while simultaneously creating legible loops and slants, crossing 't's and dotting 'i's. Pushing means it's more likely that the pen tip skips and the line gets broken.
Because writer movement is from left to right, the right handed writer has advantage of being able to see the writing as it is being executed. The left-handed writer must adjust his or her hand to compensate for the fact that the hands covering the line of writing assist it being executed.
Although the percentage varies worldwide, in Western countries, 85 to 90 percent of people are right-handed and 10 to 15 percent of people are left-handed. Mixed-handedness (preferring different hands for different tasks) and ambidextrousness (the ability to perform tasks equally well with either hand) are uncommon.
Studies suggest that approximately 10% of people are left-handed. Ambidexterity refers to having equal ability in both hands. Those who learn it still tend to favor their originally dominant hand. This is uncommon, with about a 1% prevalence.
3) Left-handers have messier handwriting
Apparently you are more likely to have messy handwriting if you are left-handed. Sarah-Jane says: “Languages that are written left-to-right, like English, are physically challenging to write with the left hand.”
If two parents are right-handed, their offspring has a 10% chance of being left-handed. However, if one or both parents are left-handed, the chance of their child being left-handed becomes higher at 18 to 22% and 27%, respectively.
Research suggests that between ten and twelve percent of the world's population is left-handed. Even though being left-handed might mean struggling with right-handed scissors from time-to-time, there are plenty of reasons being a lefty is pretty cool!

In fact, the difference is 90:10. This means that dyslexia may be more commonly found in left-handed people but the relationship is not necessarily causal. There is also the question of whether or not it is more common in boys than girls.
Why? A lefty's curveball can be a nasty pitch against right-handers, but it can also throw lefties off too. The curve can head straight for the batter then break at the last second, causing the hitter to instinctively back off. Left-handed hitters can have a particularly hard time with lefty pitchers throwing sidearm.
Many right handed kids can figure it out just fine but because positioning is a bit trickier for lefties, they may be more likely to develop bad habits that will make it harder for them to grasp and control the pencil as they get older and the writing demands increase.
Overall, individuals with ADHD had a 27.3 percent chance of being either left-handed or mixed-handed compared to 18.1 percent in the general population. So the results suggest that the effects are smaller than for the autism spectrum, but generally go in the same direction.
Abrams, which adeptly breaks down a mathematical explanation for why the rate of left-handed people has remained steady—about 10% of the population—for the last 500,000 years. The reason boils down to two words, “competition” and “cooperation,” and how the balance between those forces plays out in human societies.
Lefties--or at least relatives of lefties--may be better than right-handed people at remembering events, according to a new study. Since the mid-1980s, scientists have known that the two brain hemispheres of left-handers are more strongly connected than those of right-handers.
'If a lefty writes with his right hand it's bad, because we're changing the hand but not the leading eye or the leading foot. ' So a child who has had his hand changed is more prone to distraction; he absorbs information more poorly. As a result, he can become more irritable.
Approximately 10% of all children are left-handed: about 11% of boys and 9% of girls. These statistics are consistent with findings in the literature on handedness.
Often, the hand smears the ink or pencil as the child writes across the page. The hand also gets in the way of reading directions and examples in the left-handed margin. Because of these challenges, we often see children who will “hook” their left wrist to get their hand and wrist out of the way.
More specifically Orme (1970) found that left-handers reported themselves to be more introvert and shy than right-handers, Hicks and Pellegrini (1978) reported that left- and mixed-handers were significantly more anxious and Davidson and Schaffer (1983) reported higher trait anxiety levels in left-handers.
Take a look at their work desk. You should be able to spot the daily items such as notepad, pens, hole puncher and stapler, on his/her desk. A true blue lefty will definitely have these items set on the left side of the table for easy access.
McManus which found that the Netherlands has one of the world's highest prevalences of left-handedness at 13.23 percent. The United States isn't far behind with a rate of 13.1 percent while neighboring Canada has 12.8 percent. Elsewhere, rates of left-handedness are far lower and China is a good example.
Sex – slightly more boys than girls are left-handed. This suggests to some researchers that the male hormone testosterone has an influence on right and left-handedness. Fetal development – some researchers believe that handedness has more of an environmental influence than genetic.
One biological effect on hand preference is known to be sex, with males more likely to be left-handed than females2,14. For example, in a U.S. dataset aged 10–86 years, the proportion of non-right-handers among 664,114 women was 9.9%, versus 12.6% among 513,393 men2.
