Left-handed children struggle with a world built for right-handers, facing challenges in writing (smudging, awkward grip/hook), using tools (scissors, can openers), fitting in desks, and sometimes experiencing confusion with fine motor tasks, leading to potential frustration, poor handwriting, or even academic issues if not properly supported. They often have to adapt to left-to-right writing, which is counterintuitive, and deal with cultural biases, but with the right tools and techniques, these hurdles can be overcome.
Is it just me… or is it a left-handed thing?
One potentially important determinant of a child's cognitive development is the preference for using the left or right hand. Left- or mixed-handedness has been associated with atypical cognitive abilities, which can have both disadvantageous and advantageous outcomes (Heilman 2005).
If a left-handed child is only permitted to write with the left hand but not taught how to write, the child may develop a needlessly uncomfortable, inefficient, slow, messy way of writing that will be a lifelong hardship.
Left-handed students had a probability of suffering from ADHD 2.88 greater than right-handers. ANOVAs on standardized scores indicated that the ADHD students exhibited higher number of errors and higher variability of reaction times as compared to the controls.
Studies have consistently found a higher proportion of left-handedness among autistic individuals compared to the general population. This connection might stem from shared neurological pathways. Both autism and left-handedness involve unique patterns of brain lateralisation, which could explain the overlap.
The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
Let x be the number of left-handed people who leave the room. The resulting room will have 100 – x people and 99 – x left-handers. So the percentage that is left-handed is (99 – x)/(100 – x). The answer is surprisingly 50 left-handers have to leave, which is half of total people in the room!
things lefties find difficult
There do seem to be significantly higher births of lefthanders in July and August than expected from the normal overall trends. There is also a smaller but still significant-looking peak for lefthanders in January and February.
Taylor is a righty. I did all sorts of research and she does everything right handed.
A 2022 Psychology Today article reported an excess of gifted children among individuals who are left-handed, higher scores on verbal-reasoning tests being one indication. It has been found that left-handers often exhibit good skills in communicating through language, and many of them are very creative people.
When the Bible refers to left-handed people, it speaks of left-handedness as an advantage, not a weakness. While it is not as honorable as sitting at someone's right hand, sitting at the left hand is still a position of honor. In many religions, including Christianity, the right hand of God is the favored hand.
Key Takeaways
Left-handedness and increased risk of traumas
Many studies have indicated that left-handedness is associated with increased risk of different types of injuries. Lefties are six times likelier to die in an accident, and four times likelier to die while driving than righ-handers.
5 Fun Facts About Lefties
Barack Obama (January 20, 2009 – January 20, 2017) is left-handed.
Q: What do Steve Jobs, Bill Gates and Mark Zuckerberg have in common (besides the obvious)? A: All three belong to a community comprising about 10 percent of the population—the community of the left-handed. And they're far from the only business luminaries who are members.
Famous lefty super geniuses include Albert Einstein, Aristotle, Charles Darwin, Friedrich Nietzsche, Benjamin Franklin, and Sir Isaac Newton, according to lefthandersday.com.
Previous behavioral and scanning studies have suggested that handedness is associated with differences in brain morphology as well as in anatomical and functional lateralization.
Among the countries with relatively high rates of left- handedness: • Netherlands (~13.2 %) Statista+2LeftyFretz+2 • United States (~13.1 %) Statista+1 • Belgium (~13.1 %) LeftyFretz • Canada (~12.8 %) Statista+1 • United Kingdom (~12.24 %) LeftyFretz Rates in many Asian countries are much lower (e.g. China ~3.5 %) — ...
The ADHD "2-Minute Rule" suggests doing any task taking under two minutes immediately to build momentum, but it often backfires by derailing focus due to weak working memory, time blindness, and transition difficulties in people with ADHD. A better approach is to write down these quick tasks on a separate "catch-all" list instead of interrupting your main work, then schedule specific times to review and tackle them, or use a slightly longer timeframe like a 5-minute rule to prevent getting lost down "rabbit holes".
Increase stress relief by exercising outdoors—people with ADHD often benefit from sunshine and green surroundings. Try relaxing forms of exercise, such as mindful walking, yoga, or tai chi. In addition to relieving stress, they can teach you to better control your attention and impulses.
