Numerous studies have indicated that the brain structure of individuals with high IQs differs markedly from those of average intelligence, and this extends beyond just structure to include cognitive processes.
Recent research suggests that the brains of these individuals often exhibit superior development in certain regions, such as the prefrontal cortex, which is directly linked to complex thinking, planning, and decision-making abilities.
While traditional notions from the past associate physical traits with high IQ in children, such as bright eyes and a high forehead, modern understanding recognizes that brain development and intelligence are far more complex.
Broad Forehead
People with broad and full foreheads often convey a sense of health and intelligence. John Medina, a neuroscientist, noted that “20% of the difference in IQ between individuals is linked to brain size, particularly the size of the prefrontal cortex.”
The prefrontal cortex is considered the command center for thinking processes in the brain, responsible for problem-solving, emotion recognition, future planning, and creative thinking.
Thus, it can be said that, to a certain extent, the development of the forehead region may be associated with an individual’s intelligence.
The brain functions on the principle of “use it or lose it,” and it possesses a degree of plasticity, especially during childhood. Therefore, to enhance brain development, stimulation of the prefrontal cortex is key.
For instance, displaying empathy towards children, providing timely responses, and encouraging them to take on tasks within their capabilities are all stimulants.
For 2 to 3-year-olds, allow them to arrange picture books, read, and put away toys. For preschoolers, encourage them to dress themselves, fold clothes, put dirty laundry in the hamper, and organize dishes and cutlery.
In summary, as children grow and take on more household chores, their prefrontal cortex is effectively exercised. Additionally, reading before bedtime is an excellent way to boost brain development.
Bright Eyes
The phrase “bright-eyed and bushy-tailed” is often used to describe intelligent and quick-witted individuals. In reality, the eyes and the brain work in tandem.
Approximately 80% of the information that enters the brain is visual, and this visual data is then transmitted to the occipital lobe for processing.
For instance, when we look at an apple, the images captured by the left and right eyes differ slightly. It is only when these images are simultaneously sent to the brain and processed in the visual center that we can clearly perceive the three-dimensional, red apple.
If a child has well-developed visual recognition and reaction skills, their observations will be accurately and swiftly transmitted to the brain.
Superior visual cognitive abilities give children greater confidence in their learning and other activities. They can easily translate their imagination into drawings, write with precision, and quickly grasp the main ideas and author’s intent when reading.
In summary, excellent visual capabilities offer numerous benefits to a child’s life and learning experiences.
The most significant development of the occipital lobe typically occurs before the age of four. Encouraging activities such as paper folding, block building, chess, puzzles, and educational games within the first six months after birth can help foster the development of “bright eyes” and also stimulate the prefrontal cortex.
Ever-Present Smile
It is often said that children who smile frequently are not only lucky but also tend to be more intelligent.
Within the brain, there is an almond-shaped structure called the amygdala, which regulates emotions such as happiness, anger, and sadness. When we experience happiness, this area becomes active, stimulating the adjacent anterior cingulate cortex (ACC), resulting in a smile.
When we feel excited, the ACC is also activated, releasing beta-endorphins that soothe emotions, maintain emotional stability, and induce a sense of happiness.
Therefore, a smile not only fosters a positive attitude in children but also contributes to their overall well-being.
Additionally, our brains contain mirror neurons that enable us to empathize and behave similarly to those around us.
When a child smiles at someone, it not only indicates that the caregiver is also happy but also signifies bonding and friendship between them. This demonstrates that the caregiver has created a safe and comfortable environment for the child, fostering a sense of security and satisfaction.
The human brain prioritizes survival above all else. When children feel secure and are not burdened by negative emotions, they can freely explore their surroundings, venture into new domains, develop skills, and enhance their intelligence.
While physical traits may provide some indication of a child’s intelligence, it is essential to recognize that intelligence is influenced by a multitude of factors, including educational environment, nurturing, and life experiences.
