Left-handed people are more likely to be reserved, anxious, shy and embarrassed than their right-handed counterparts, according to a new study. Left-handed people are more likely to be reserved, anxious, shy and embarrassed than their right-handed counterparts, according to a new study.
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.
A recent study shows that lefties are, in fact, more easily scared. Researchers found that left-handed people displayed more classic signs of post traumatic stress disorder while watching Silence Of The Lambs than their right-handed counterparts.
According to a small study published in the Journal of Nervous and Mental Disease, lefties are more prone to having negative emotions. In addition, they seem to have a more difficult time processing their feelings. Again, this seems to be related to the brain-hand connection.
Some studies show that left-handed people showed an imbalance in processing emotions with their left and right hemispheres of their brain. Left-handed people have a higher risk of brain disorders like schizophrenia, dyslexia or hyperactivity disorders.
Why are some people left-handed? - Daniel M. Abrams
Why are lefties so special?
Lefties make up only about 10 percent of the population, but studies find that individuals who are left-handed score higher when it comes to creativity, imagination, daydreaming and intuition. They're also better at rhythm and visualization.
Similar results were also reported by a recent study that investigated left-handedness in the UK Biobank study, a large dataset with about 500,000 participants (de Kovel et al., 2019). Here it was found that in the UK, 8.6 percent of women and 10.6 percent of men were left-handed.
End of dialog window. However, results from a 2009 study by Stanford University concluded that left-handed people may indeed think different to those who are right handed, or at least, they see the world a little differently.
Results: Psychopaths reported reduced right-hand dominance, which cannot be accounted for by differences in age, intelligence, or race. Conclusions: Psychopathy is associated with an increased proportion of mixed-handedness relative to that seen in nonpsychopathic persons.
The experiment worked – and corroborated the researchers' first test of the sword and shield hypothesis using brain imaging. Strong righties who were zapped in the left hemisphere experienced a boost in positive emotions. So did strong lefties zapped in the right hemisphere.
Left-handed and ambidextrous people are more susceptible to negative emotions, including anger. A small study published last year in the Journal of Nervous and Mental Disease found that the brains of lefties process emotions differently than those of righties, with more communication between the brain's two halves.
The left hemisphere, which controls the right hand, likes rapidly-changing sounds like consonants, while the right hemisphere, which controls the left hand, likes slowly-changing sounds like syllables or intonation.
Although data suggested that right-handed people had slightly higher IQ scores compared to left-handers, the scientists noted that intelligence differences between right and left-handed people were negligible overall.
Are left-handed people more likely to be depressed?
It is found that, using three different measures, left-handers are significantly more likely to have depressive symptoms than right-handers. For example left-handers are about 5% more likely to have reported having ever experienced symptoms of depression compared to about 27% of the total sample.
According to a recent survey, lefties are 71% more satisfied in the sack than righties. Of the 10,000 people surveyed, 86% of left-handed people reported being “Extremely Satisfied” with their sex lives, compared to just 15% of righties.
Researchers found that among patients with mood disorders like depression and bipolar disorder, 11 percent were left-handed, about the same rate as in the general population. But when they examined patients with schizophrenia and schizoaffective disorder, they found that 40 percent were left-handed.
This study suggested that they were. Specifically, left-handers were found to be more fluent, flexible, original and elaborate when drawing pictures and answering questions, giving explanations, imagining consequences, and coming up with different uses for objects.
A well-publicized study in the early 1990s, for instance, reported that lefties had shorter life spans than righties, but those results have since been discredited. Subsequent research found no meaningful differences in mortality rates.
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.”
To make their handwriting slant the right way, the majority of left-handed people twist their wrists clockwise, so they're writing from above: This form of writing, known as crabclaw, leads to smeared ink (or smudged graphite), prevents the writer from seeing what's been written, and is uncomfortable.
Various surveys have found that the highest incidence of left-handedness is in Western countries. The Netherlands, the USA and Canada lead with around 13 per cent of the population being left-handed and the UK is only just behind.
Left-handedness occurs in about 8% of the human population. It runs in families and an adoption study suggests a genetic rather than an environmental origin; however, monozygotic twins show substantial discordance.
You may have heard that left-hand dominance is a sign of a learning disability. Rest assured, in most cases, left-handedness is a normal part of child development. While it is possible for left-handedness to coexist with learning disabilities or other health concerns, this is the exception and not the rule.
