In 1981, neuroscientist Roger W. Sperry was awarded the Nobel Prize in Physiology or Medicine. His discovery revealed that the brain's hemispheres function differently and are responsible for distinct aspects of bodily control and cognitive processing. Roger W. Sperry's theory states that the left and right hemispheres of the brain control the body's organs in a bilaterally symmetrical manner: the left brain right brain theory also suggests that certain personality traits and specific abilities are governed by different hemispheres.
Understanding the Left Brain vs. Right Brain Theory
Research on the functional specialization of the brain's hemispheres has shown that each person has strengths and weaknesses depending on which hemisphere is dominant. Looking at a left brain vs right brain characteristics chart, you will notice that the left hemisphere is responsible for logic and analytical thinking, while the right hemisphere is associated with intuition, emotions, and creativity.

If both hemispheres function equally, a person falls into the category of middle-brained or whole-brained thinkers, possessing a balanced blend of analytical and creative thinking. According to this theory, people naturally have a dominant side, making them either more structured, analytical, and logical or more creative, visually oriented, and intuitive. To determine whether you are left-brained or right-brained, simply look at the table above and compare which traits are more dominant in your thinking style.
Left Brain Versus Right Brain: Debunking the Myths
The left brain versus right brain theory gained immense popularity over the years. The idea that the left hemisphere controls the right side of the body and vice versa has been supported by evidence from stroke cases, where damage to one hemisphere affects the bilaterally symmetrical side of the body. However, neuroscientists didn’t stop there. In 2023, researchers revisited the left brain versus right brain theory, publishing a study in Trusted Source based on MRI scans of 1,000 participants.
The MRI results revealed that the human brain does not prefer one side over the other. Instead, nerve fiber bundles form extensive pathways between the hemispheres, meaning they work together. Both hemispheres function simultaneously; you never use only one. While it was previously believed that the left brain handled mathematical problems, new research indicates that the right hemisphere also activates when spatial awareness is required during complex calculations.
-
Myth: Each part of the brain is responsible for a specific function.
-
Truth: The human brain is a complex, harmonious system where no region functions in isolation. Both hemispheres interact through neural fibers, particularly the corpus callosum, which connects them. Every healthy individual who underwent research uses both hemispheres equally. Whether performing logical reasoning, engaging in creativity, analyzing data, or making decisions, both hemispheres are actively involved. Logical thinking does not occur exclusively in the left hemisphere, just as creativity is not solely a right-brain function.
While some specialization exists (for example, the left hemisphere is more involved in language, whereas the right hemisphere plays a bigger role in spatial awareness and emotional processing), most cognitive processes engage both hemispheres simultaneously.
The connection between hemispheric dominance and analytical or creative thinking remains unproven. Neither hemisphere is superior or inferior, nor is one more or less developed. Skills and abilities are the result of effort and practice.
When discussing left brain versus right brain, it’s essential to focus on harmoniously developing both hemispheres, fostering a well-rounded individual. Ultimately, we are all whole-brained thinkers from childhood. The real question is how to maximize the potential of both hemispheres.
Left Brain Versus Right Brain: How Montessori Develops Both Hemispheres
So, in the left versus right brain debate, there are no winners. Until newer research provides conclusive evidence on whether hemispheres determine talents, parents should focus on balanced development, fostering both creativity and analytical skills. The Montessori method takes a holistic approach to education, valuing logic and creativity, organization and abstract thinking.
Montessori Practices for Left Brain Development
Since left-brain cognitive style is characterized by analytical thinking, logic, rationality, and critical reasoning, Montessori exercises target these specific skills:
-
Montessori math manipulatives (number rods, abacus, counting beads, and math boards) help children understand numerical concepts.
-
Montessori puzzles, busy boards, and classification games (e.g., shape sorters) strengthen logical reasoning.
-
Magnet games and simple physics experiments provide hands-on opportunities to explore cause-and-effect relationships.
Montessori Practices for Right Brain Development
Right-brain development, which governs imagination, creativity, artistic expression, and empathy, is encouraged through:
-
Clay modeling
-
Painting and drawing
-
Sensory play
-
Pretend play
-
Music and rhythm activities
Montessori Brain-Boosting Activities
The key feature of Montessori education is that each activity nurtures both analytical and creative thinking. This inter-hemispheric learning is the most effective way to develop new skills because it engages multiple cognitive functions simultaneously.

Practical Tips for Parents and Educators
What can you do with what you have just learned about the left brain vs. the right brain? Quite specific things:
Create a Balanced Learning Environment
In the article "Child Brain Development," you can find detailed information about the milestones of brain development that every child goes through from birth to school age. Understanding these stages and a child’s readiness for certain tasks is more important than trying to "train" the left or right brain. Instead, it is better to create an environment that supports the development of all cognitive functions according to age.
Encourage a Variety of Age-Appropriate Activities
Numbers can be drawn, colored, and cut out on paper. While climbing a ladder, a child can count the steps, learn colors, or solve riddles. When playing in the sand, sensory activities can be combined with practical skills—such as sifting sand through a sieve or scooping and pouring it. Try integrating logic with creativity, active play with learning—this ensures a well-rounded approach and harmonious development.
Learning Through Play
This is one of the key ideas of Montessori education. She observed that children learn best when the process is engaging, fun, and playful. This applies to both children who may later excel in math and those who will write poetry or create artistic masterpieces. Play also encourages both logic and creativity to work together, promoting comprehensive development.
Final Thoughts
The Montessori approach does not aim to categorize children or determine a "winner" in the left brain vs. right brain debate. It is based on the idea of holistic development and recognizes that play, physical activity, music, rhythm, and hands-on experiences significantly enhance learning and information processing. Montessori activities, tailored to a child's age, provide a balance between left- and right-brain learning. Ultimately, this allows children to unlock their full potential in both logical and creative areas without limitations.
