To test this negative perceptual frequency effect hypothesis, we invited 18 skilled and 18 novice volleyball players to predict shot directions of left- and right-handed attacks in a video-based visual anticipation task. In accordance with our predictions, and with recent reports on laterality differences in visual perception, the outcome of left-handed actions was significantly less accurately predicted than the outcome of right-handed attacks. In addition, this left—right bias was most distinct when predictions had to be based on preimpact i. Left-handed opponents present an interesting obstacle to many athletes in interactive sports. One explanation for this phenomenon is the negative frequency-dependent selection hypothesis proposed by Faurie and Raymond They supposed that the superiority of left-handed athletes in interactive sports is the result of players having less experience with left-handed opponents. The lack of familiarity with the playing techniques and tactical strategies of left-handed competitors therefore disadvantage a player to act the same as when faced with a right-hander e. As a result, the inexperience of those players ultimately creates an advantage for their left-handed opponent cf. Although a left-handed action may seem to be simply a horizontally inverted version of a right-handed action, assuming that interpreting left- and right-handed actions does not involve different cognitive processes may be misleading. Neuropsychological and psychological evidence suggest that the horizontal orientation is an important part of perceiving human motion.

The journal Biology Letters published a study that suggests that being a lefty is a big advantage in sports which rely heavily on reactions where time pressures are particularly severe, such as table tennis, cricket and baseball. The reason for this is because right-handers are far more overrepresented and common in all walks of life so their movements are a lot more familiar compared to those of the underrepresented left-handers, thus giving them less time to adjust. This could be a reason for why Mitchell Johnson has had so much success in the Ashes in the past.

The first time you picked up a crayon as a small child, you probably felt more comfortable and more natural drawing with one of your hands than the other one.

That uneven split has had some historic downsides for lefties.
They’ve had to use scissors, desks, knives and notebooks that were designed with righties in mind.

They’ve been discriminated against and eyed with suspicion, as evidenced in the language used to describe lefties. While the stigma against left-handedness has faded in most places, scientists are still confounded by the righty-lefty divide.
Researchers are still trying to understand what makes people prefer one hand over the other and why righties dominate. On an individual level, handedness might be determined at the earliest stages of development. Scientists reported in i n the journal Neuropsychologia that fetuses will show a hand preference in the womb by sucking the thumb of one hand , a proclivity that continues after they’re born.
While there’s no righty or lefty gene, DNA does seem to play a role in handedness. Three out of these four regions were involved in brain development and structure.

One way to look at the contrast between lefties and righties, according to psychologist Yvonne Thomas, PhD, is how they approach problem solving. While those on the right might apply logical solutions to an issue, she explains that lefties have the innate ability to come up with several options, as opposed to just one black-and-white route.
Reznick has experienced this personally, explaining she often sees or feels the general idea of the task at hand, rather than needing to break down an issue into specific, tangible parts. This is juxtaposed with her right-handed sister who will make logical points that form the basis for her opinions, decisions, and behavior.

The study is a fascinating one, using thousands of brain scans and hundreds of thousands of sequenced genomes to look for associations between genes, brains and hands. It found that, in left-handers, the left and right hemispheres had stronger links in the regions associated with language, which could correlate with greater language ability.
Left-handedness runs in families and identical twins are more likely to have the same hand dominant than are fraternal twins and siblings.
