Does Early Talking or Late Talking Indicate a Higher IQ in Children?

The Two “Language Factories” in the Brain

The brain has two regions, Broca and Wernicke, akin to language factories. While Broca is responsible for sentence construction (the motor language center), Wernicke handles comprehension (the sensory language center).

However, what we may not realize is the significant difference in the “opening hours” of these two regions. Some children form complex sentences like “Mommy, carry me to see the flowers” as early as 18 months old.

In contrast, others may not grasp complete grammar until they are 3 years old (in some special cases, children may not call their parents until this age or speak fluently until they are 4). This gap spans 18 months.

The secret lies in the “insulation” of neurons. Just as electrical wires need rubber insulation, the myelin sheath of brain neurons determines the speed of information transmission.

For some, the Broca region starts “insulating” right from birth, while for others, it may not develop rapidly until after age 2. It’s like some factories invest in assembly lines first, while others stockpile raw materials, simply different strategies.

Using DTI imaging technology, researchers found that for late talkers, the “highway” (tract) connecting language regions in the brain could be quietly expanding to eight lanes in both directions. Although these children’s current output is slow, their future information integration capabilities may be stronger.

The “Superpower” Battle Between Early and Late Talkers

Take the example of a set of twins. The older brother could say “mommy” and “daddy” at 10 months, but the younger one didn’t speak until he was 2.

By age 5, the older brother could vividly describe exciting kindergarten events, but he struggled to assemble shapes according to instructions when playing with Lego. Conversely, the younger brother, a late talker, used few words but could swiftly assemble a complex warship by merely looking at the design blueprint. This is not a coincidence.

In fact, brain scientists have discovered that:

Early Talkers Often Have

– A Super-Strong “Language CPU”: The left brain’s language region completes specialized division of labor early on, akin to installing a grammar acceleration program.

– Enhanced Memory: They can quickly store heard words in their “brain hard drive” (hippocampal activity is 23% higher).

– Potential Social Expertise: As early as 18 months, they use eye contact and speech to attract adult attention.

Both early and late talkers have their unique strengths and weaknesses.

Late Talkers May Possess

– Spatial Abilities: The dorsal visual region seems equipped with 3D modeling software, and their spatial skills may surpass their peers.

– Logical Thinking: When solving problems, their frontal lobes use more sensory information, akin to playing a real-life version of the “Escape Room” game.

– Observational Skills: They are more sensitive to subtle changes in facial expressions (15% higher activation in the insula than early talkers).

Thus, each child has their unique strengths. Parents can act like gardeners, nurturing each child’s “roots” and “turning the soil” regularly, allowing them to flourish naturally.

Misunderstanding Late Talkers as Having Issues

In reality, the brain has a super-intelligent “compensation mechanism.” When the language region develops slowly, other brain regions temporarily form a team to provide support. The brains of late talkers undergo these wondrous changes:

– The Visual Region Becomes a “Temporary Translator”: It directly converts visual information into understanding. Hence, late talkers often have a strong sense of direction.

– The Motor Region Engages in “Body Coding”: They use actions instead of verbal output, excelling in gestures.

– The Brain’s Default Network Activates “Background Learning”: It automatically organizes language materials during silent periods (one day, this may lead to a vocabulary explosion).

However, note that if a child is over 3 and doesn’t understand simple instructions (like “Give the ball to mommy”), lacks eye contact or gestures, or reacts slowly to sounds, consult a doctor to rule out any underlying issues.

The Brain Naturally Levels Out Over Time

Each child has their unique strengths and weaknesses. Parents can customize an educational plan based on their child’s language development type.

For Early Talkers

– Play Interactive Games: Start a story with “Once upon a time, there was a mountain”, and ask your child to continue with “There was a big white rabbit on the mountain”.

– Practice Retelling: Encourage your child to be the “little anchor” after watching cartoons or listening to stories, retelling them in their own words.

However, focus on depth of understanding and avoid overdeveloping their memory skills.

Customize educational plans based on your child’s language development.

For Late Talkers

– Invent “Body Codes”: For instance, clapping represents an apple, and jumping means going out to play.

– Play the “Guess the Toy” Game: Hide a toy behind your back and have your child guess it through gestures.

– Use Visual Aids More Often: Combine reading and writing skills with real objects, building a “picture-vocabulary” bridge, seamlessly integrating spatial structure with language input.

For example, if your child uses Lego blocks to build a red house, say, “You want to build a red house? So, what should we do with the blue blocks?” Research shows that this method increases late talkers’ vocabulary by 40%.

According to other studies, regardless of early or late talking, by age 7, the brain network’s efficiency naturally levels out. The differences that once caused concern are resolved thanks to the brain’s remarkable adaptability.

Each child evolves through distinct neural development paths, the smartest survival strategy. Some flowers bloom in spring, while others bloom in autumn. Some develop language first, while others hone observation skills to detect dangers. It’s all part of the wisdom embedded in our DNA.

So, if your child talks later than their peers, don’t fret. Brain development is not a sprint but a marathon with varying paces. Your role as a parent is to provide abundant love and patience, letting each “flower” bloom in its own time.
