Ambidextrous refers to the ability to use both hands with equal skill and dexterity. This rare trait is present in only about 1% of the population, which equates to approximately 80 million people worldwide. While most individuals have a dominant hand (either right or left) that they prefer for tasks requiring fine motor skills, ambidextrous people can perform such tasks equally well with either hand. This ability extends beyond just writing and can include activities like throwing, eating, or using tools. It’s important to note that true ambidexterity is different from mixed-handedness, where a person may prefer different hands for different tasks. Some ambidextrous individuals may have developed this skill through practice or necessity, such as left-handed people adapting to right-handed tools, while others may have a natural predisposition towards using both hands equally.
Types of Ambidexterity
It generally refers to the ability to use both hands with equal skill. However, in a broader context, especially in organizational and cognitive sciences, ambidexterity can be categorized into several types:
1. True Ambidexterity
True ambidexterity refers to the rare ability of an individual to use both hands with equal skill and dexterity. This form of ambidexterity is often considered innate and is not commonly found in the general population. Genetic studies have shown that true ambidexterity is associated with specific genetic variants, although these are distinct from those linked to left-handedness. True ambidexterity can be advantageous in various fields, such as sports and surgery, where the ability to perform tasks with either hand can enhance performance and efficiency.
2. Learned Ambidexterity
Learned ambidexterity is the ability to use both hands proficiently, developed through practice and training rather than being an innate trait. This type of ambidexterity is particularly relevant in professions requiring high levels of manual dexterity, such as neurosurgery and laparoscopic surgery. Studies have shown that with consistent practice, individuals can improve their non-dominant hand’s skills, leading to better overall performance in tasks requiring bilateral coordination. This acquired skill can be crucial in situations where reliance on a single hand is not feasible or optimal.
3. Ambilevous
Ambilevous, also known as cross-dominance or mixed-handedness, refers to individuals who do not have a strong preference for one hand over the other and may switch hands depending on the task. Unlike true ambidexterity, ambilevous individuals may not have equal proficiency with both hands but can use either hand for different activities. This trait is less about equal skill and more about flexibility in hand usage. Research indicates that ambilevous individuals may have unique neural pathways that allow for this flexibility, although it is not as well understood as other forms of handedness.
4. Cross-Dominance (Mixed-Handedness)
Cross-dominance, or mixed-handedness, is characterized by the use of different hands for different tasks, without a clear dominant hand. This form of ambidexterity is relatively common and can be seen in individuals who might write with one hand but perform other tasks, such as throwing a ball, with the opposite hand. Studies suggest that cross-dominance may be linked to specific genetic and environmental factors that influence hand preference and motor skills. This trait can be advantageous in various activities that require diverse hand movements and coordination.
5. Cultural or Situational Ambidexterity
Cultural or situational ambidexterity refers to the ability to use both hands proficiently due to cultural practices or specific situational demands. In some cultures, individuals are encouraged to develop ambidextrous skills from a young age, leading to a higher prevalence of ambidexterity in those populations. Additionally, certain professions or activities may necessitate the use of both hands, prompting individuals to develop ambidextrous abilities. This form of ambidexterity highlights the role of environmental and cultural factors in shaping hand preference and dexterity.
Causes of Ambidextrous
These factors can be broadly categorized into genetic influences, environmental conditioning, and neurological development. Below are some of the primary causes of ambidexterity:
1. Environmental and Cultural Influences
Environmental and cultural factors play a significant role in the development of ambidexterity. Research indicates that organizational culture, particularly one that supports alignment and adaptability, is crucial for fostering ambidexterity within firms. For instance, a study found that environmental munificence strengthens the relationship between ambidextrous organizational culture and contextual ambidexterity, leading to improved innovation outcomes. Additionally, the gestational environment, such as birth season, has been shown to influence lateral dominance, suggesting that environmental factors during early development can impact ambidexterity.
2. Developmental Factors
Developmental factors, including early life experiences and educational environments, significantly influence ambidexterity. Studies have shown that individual ambidexterity is affected by personal skills in handling work stress and building trust, which are developed over time through various experiences. Furthermore, the relationship between lateral dominance and birth season highlights the impact of developmental timing on ambidexterity, suggesting that the conditions during gestation and early childhood can shape an individual’s ability to use both hands effectively.
3. Genetic Factors
Genetic factors are also crucial in determining ambidexterity. Some researchers argue that cerebral dominance and laterality are genetically determined, similar to traits like eye color and blood type. This genetic predisposition can influence whether an individual is right-handed, left-handed, or ambidextrous. However, the interplay between genetic and environmental factors is complex, and both contribute to the development of ambidexterity. For example, while genetic factors set the foundation, environmental influences during gestation and early life can modify these genetic predispositions.
4. Brain Hemisphere Connectivity
The connectivity between brain hemispheres is a fundamental factor in ambidexterity. Effective communication between the left and right hemispheres of the brain is essential for coordinated use of both hands. Research on cerebral laterality suggests that both genetic and environmental factors influence this connectivity, impacting an individual’s ability to develop ambidextrous skills. Enhanced inter-hemispheric communication can lead to better integration of motor functions, thereby facilitating ambidexterity.
5. Neurological and Physical Factors
Neurological and physical factors, including brain structure and motor skills, are critical in the development of ambidexterity. Studies have shown that organizational trust and formalization can influence ambidexterity by affecting neurological and physical responses to tasks. Additionally, individual skills in handling work stress and building trust are linked to better performance and ambidextrous behavior, indicating that neurological resilience and physical adaptability are important for ambidexterity. These factors collectively contribute to an individual’s ability to use both hands effectively in various tasks.
