Unleashing the Power of Left-Handedness: Exploring the Advantages of Being Left-Handed

Unleashing the Power of Left-Handedness: Exploring the Advantages of Being Left-Handed

Left-handedness, a natural phenomenon that has intrigued scientists and societies for centuries, refers to the preference of using the left hand over the right hand for various activities. Approximately 10% of the global population is left-handed, making it a relatively rare trait. While left-handedness is often seen as a unique and intriguing characteristic, it has also been associated with certain advantages and disadvantages. In this article, we will delve into the advantages of being left-handed, explore its presence in different cultures, examine famous left-handed individuals, discuss its impact on sports, address the challenges and misconceptions surrounding left-handedness, explore the concept of ambidextrousness, and highlight specialized products and tools for left-handed individuals.

The advantages of being left-handed

Being left-handed can provide individuals with various advantages. One significant advantage is enhanced creativity. Studies have shown that left-handed individuals tend to have a more developed right brain hemisphere, which is associated with creativity and artistic abilities. This may explain why a significant number of artists, musicians, and writers are left-handed. Additionally, left-handed individuals often possess increased problem-solving skills and are adept at thinking outside the box, which can be advantageous in many professional fields.

Another advantage of being left-handed is improved spatial reasoning. Left-handed individuals typically have a more developed right parietal cortex, which is responsible for spatial awareness and visualization. This enhanced spatial reasoning can be beneficial in activities such as architecture, engineering, and sports that require precise coordination and understanding of spatial relationships.

Left-handedness has also been linked to better multitasking abilities. Research suggests that left-handed individuals have a higher degree of interhemispheric connectivity, allowing for more efficient communication between the brain’s two hemispheres. This enhanced connectivity enables left-handed individuals to excel in tasks that require simultaneous processing of multiple sources of information, such as driving while talking on the phone or multitasking in a fast-paced work environment.

Left-handedness in different cultures

Throughout history, left-handedness has been viewed differently across various cultures. In some cultures, being left-handed was considered taboo or associated with negative connotations, leading to discrimination and attempts to convert left-handed individuals to right-handedness. However, in other cultures, left-handedness was celebrated and considered a sign of uniqueness and special abilities.

For example, ancient Egyptians believed that left-handedness was a divine characteristic, associating it with the goddess Isis. In certain African cultures, left-handed individuals were believed to possess spiritual powers and were revered as healers or shamans. In contrast, many Western societies historically viewed left-handedness as a sign of evil or witchcraft, leading to societal pressure to convert left-handed individuals to right-handedness.

Fortunately, the perception of left-handedness has evolved over time, with greater acceptance and recognition of its natural occurrence. Today, many cultures celebrate left-handedness and highlight the advantages and unique qualities associated with being left-handed.

Famous left-handed individuals

Left-handedness has been prevalent among numerous famous individuals throughout history. From artists and athletes to politicians and scientists, left-handedness has not hindered the success of these individuals but has often contributed to their achievements. Some notable left-handed actors include Leonardo DiCaprio, Tom Cruise, and Julia Roberts, who have captivated audiences with their exceptional acting skills and charisma.

In the realm of music, left-handed musicians such as Jimi Hendrix, Paul McCartney, and Kurt Cobain have left an indelible mark on the world of music with their innovative styles and groundbreaking compositions. Their left-handedness brought a unique perspective to their craft, contributing to their iconic status in the music industry.

From a scientific standpoint, left-handed individuals such as Albert Einstein and Marie Curie have made significant contributions to their respective fields, showcasing that left-handedness is not a hindrance but rather a characteristic that can coexist with exceptional intelligence and groundbreaking discoveries.

These examples serve as a testament to the fact that left-handedness is not a limitation but rather an asset that can contribute to remarkable achievements in various domains.

Left-handedness in sports

Left-handedness can provide a competitive edge in the world of sports. In many sports, left-handed athletes possess a natural advantage due to their opponents’ relative lack of experience in facing left-handed competitors. This unexpectedness can disrupt the opponent’s usual strategies and provide left-handed athletes with a higher chance of success.

For instance, in tennis, left-handed players often have an advantage over right-handed players due to the difference in spin and angle of the ball when it is struck by a left-handed player’s racket. This can create difficulties for right-handed opponents in adjusting their shots and positioning on the court.

Similarly, in combat sports such as boxing or martial arts, left-handed fighters, known as southpaws, often pose challenges for their right-handed opponents. The reversed stance and different angles of attack can catch right-handed opponents off guard and require additional adaptation and strategy.

Left-handedness can also be advantageous in team sports such as basketball or soccer. Left-handed players can provide a unique playing style and contribute to the team’s tactical diversity. Their left-handedness can create unpredictable situations for the opposing team, as they are accustomed to defending against right-handed players.

Challenges and misconceptions about left-handedness

Despite the advantages associated with being left-handed, there are also challenges and misconceptions that left-handed individuals may encounter. One common misconception is that left-handed individuals are less intelligent or more prone to certain health conditions. However, scientific research has debunked these myths, reaffirming that left-handedness is simply a natural variation in human development with no inherent disadvantages.

One challenge that left-handed individuals may face is the lack of left-handed products and tools in a right-handed dominant world. Many everyday objects, such as scissors, can openers, and desks, are designed for right-handed individuals, which can make certain tasks more challenging or uncomfortable for left-handed individuals. However, with increasing awareness and demand, there has been a growing availability of specialized products and tools designed specifically for left-handed individuals, alleviating these challenges to some extent.

Ambisinistrousness: The ability to use both hands equally well

While left-handedness is often associated with a preference for using the left hand, some individuals possess the unique ability to use both hands equally well. This phenomenon is known as ambisinistrousness. Ambisinistrous individuals are not strictly left-handed or right-handed but have a high degree of ambidexterity.

Ambisinistrousness can be advantageous in various situations. Individuals with this ability can effortlessly switch between hands, allowing them to adapt quickly to different tasks and situations. This flexibility can be particularly beneficial in activities that require fine motor skills or coordinated movements.

Ambisinistrous individuals often excel in musical instruments that require both hands, such as piano or guitar, as they can seamlessly navigate the keys or strings with either hand. Additionally, ambisinistrousness can be advantageous in sports that demand bilateral coordination, such as fencing or archery.

Left-handed products and tools

Recognizing the unique needs of left-handed individuals, there has been a growing market for specialized left-handed products and tools. From left-handed scissors with reversed blades to left-handed keyboards and computer mice, these products are designed to provide comfort and ease of use for left-handed individuals.

Left-handed desks and writing instruments with a slant towards the left are also available, enabling left-handed individuals to write without smudging the ink or experiencing discomfort. Additionally, specialized kitchen utensils, such as left-handed can openers and peelers, have been developed to facilitate food preparation for left-handed individuals.

The availability of these specialized products and tools has significantly improved the overall experience for left-handed individuals, allowing them to navigate a right-handed dominant world with greater comfort and efficiency.

Tips for left-handed individuals

If you are left-handed, here are a few tips to enhance your experience and make daily tasks more manageable:

  1. Embrace your left-handedness: Recognize that being left-handed is a unique and valuable trait that contributes to your individuality. Embrace it with pride and celebrate your differences.
  2. Seek out left-handed products and tools: Invest in specialized left-handed products and tools that cater to your needs. This will make everyday tasks more comfortable and efficient.
  3. Develop ambidexterity: Practice using your non-dominant hand to improve your ambidexterity. This can be done through simple activities such as brushing your teeth or writing short notes.
  4. Be aware of your surroundings: Pay attention to the layout of objects and tools in your environment. Make adjustments, if necessary, to ensure optimal comfort and functionality.
  5. Educate others: Inform friends, family, and coworkers about the challenges that left-handed individuals may face. By raising awareness, you can help create a more inclusive and accommodating environment for all.

Embracing and celebrating left-handedness

Left-handedness is a fascinating characteristic that has both advantages and challenges. It is important to recognize and celebrate the unique qualities that left-handed individuals bring to the world. By understanding the advantages of being left-handed, appreciating its presence in different cultures, acknowledging the accomplishments of famous left-handed individuals, and addressing the challenges and misconceptions surrounding left-handedness, we can create a more inclusive and supportive society for all individuals, regardless of their dominant hand. So, let us embrace and celebrate the power of left-handedness.

Edinburgh Napier’s Repository – a home for the university’s research

Edinburgh Napier’s repository – a home for the university’s research

A repository is a kind of digital archive for storing all the research outputs created by a university’s academics and researchers. Most importantly, it also makes much of this research publicly available for everyone to read and download. The Edinburgh Napier Research Repository is the home for Edinburgh Napier’s research. We moved to the current repository platform earlier this year, so it might look a little different now if you were familiar with the old one.

Open Access

Making research open access in the repository benefits researchers whose work can be more widely read and cited. It’s also great for students who can access research much more easily. Almost every university has a repository now.  so you can use aggregator services like CORE to find research from around the world. CORE includes the 20,000+ outputs from Napier’s repository and millions more as well. Take a look at our open-access LibGuide with more tips for finding open-access research.

WorkTribe

For Edinburgh Napier academics and researchers who want to curate their own profile or add new research outputs to the repository, just log in to Worktribe using your usual university credentials. If you need any help, check out the support pages on the intranet or feel free to email repository@napier.ac.uk with any questions about open access – including publishing open-access journal articles using one of the library’s publisher deals.

The repository is not just for academic staff though. In fact, Research students can be set up with a profile if they have publications to share. Furthermore, all postgraduate theses awarded by Edinburgh Napier are made available in the repository and then included in the British Library’s national thesis collection for anyone to read.

And that’s what repositories are all about. Making it easier for everyone to find and share the knowledge our universities create.

National Insect Week 2022

National Insect Week 2022

Love them or loathe them, insects are an important part of the earth’s ecosystem. Furthermore, they are a vital source of food for birds, fish and animals. In addition, they pollinate crops and plants and break down plant and animal matter. Over one million species of insects have been discovered and described, but it is estimated that there may be as many as 10 million species on earth. Scientists estimate that insects make up to 90% of all species of animals on the planet and more than half of all living things.

All insects have:

  1. Six legs.
  2. Three body sections (head, thorax and abdomen)
  3. Pair of antennae.
  4. Compound eyes.
  5. Most have wings.
  6. Three or four stage life cycle (egg, larva or nymphs, pupa and adult)

Insects can be found in every habitat on earth from hot deserts to snow-covered mountains, some such as termites and ants live in large colonies. Others, like the praying mantis and some bees and wasps, are solitary only coming together to mate.

Insects in trouble

It has been well documented in recent years that insects are under pressure due to loss of habitat, climate change and chemicals used in farming. It is estimated that every minute an area of rainforest the size of a football pitch is being cleared, displacing the insects that occupied it. In addition, Insects are also being killed by pesticides and herbicides designed to increase crop yields.

To reduce the impact scientists are trying to develop disease-resistant crops. This will lessen the need for harmful chemicals. Also farmers are being encouraged to develop wildlife strips to try to boost insect numbers.

Honey bees are also under threat from the varoa mite . It attaches to the body of the bee and sucks out fat bodies and also feeds on the larvae in bee hives. Moreover, these mites are a vector for at least five different debilitating bee viruses contributing to the current higher levels of bee losses worldwide.

How can you help this National Insect Week 2022?

You may think that there’s little you can do to help the insects’ plight, but there are some simple and cheap things you can try at home. Should you have a garden, you can leave a wild area where you don’t cut the grass, let weeds and nettles flourish and leave tree branches where they fall. This provides shelter and dedicated space for insects to thrive. Also, you can try planting flowers and shrubs which are good for insects in your flower beds or planters.

Don’t have a garden? You could plant up a window box with bee-friendly flowers such as cornflowers, cosmos and pot marigolds. These can be bought for a relatively small price.

Bug hotels are a fantastic way to provide shelter and a breeding spot for insects. They can be purchased at garden centres and online, but you may like to try making your own. There are several tutorials on YouTube and it’s a great way of recycling old materials and garden waste which you might have lying around.

Alternatively, you could take part in citizen science projects to help scientists better understand how insects are coping and if their populations are in decline or expanding.

Examples of citizen science projects are:

Garden butterfly survey- https://gardenbutterflysurvey.org/

UK ladybird survey-https://www.coleoptera.org.uk/coccinellidae/home

A future food source?

In some countries, insects are seen as delicious snacks. Walk around a market in many parts of Asia and you will almost certainly come across fried grasshoppers and mealworms on the menu. This concept seems very alien to us in Scotland, but some scientists believe that there is a need for us to start using insects as a food source. The ever-increasing global population and events such as wars put pressure on food commodities. This can cause shortages, which if they were long-term, could mean that we must consider some more unusual sources to feed the world’s population.

Edinburgh Napier has lots of books and articles about insects available at Sighthill campus library and online. Use Library Search to find them.
