How Talking to Your Baby Can Boost Their Brain Development
A team of researchers from the University of Texas at Dallas has recently uncovered conclusive evidence that says the more parents talk to their babies, the more they help their brain development. Parents who talk to their babies regularly can enhance their language skills as they grow older. Lead researcher Dr. Meghan Swanson, who is an assistant professor of psychology in the School of Brain and Behavioral Sciences, used MRIs and audio recordings to conduct the study. The research team imaged various areas of the brain’s white matter to examine the developing neurological pathways and discovered that slower white matter maturation confers a cognitive advantage.
Results of the Study Highlight the Importance of Talking to Children
The findings of the study have significant implications for cognitive scientists, pediatricians, and parents, as it underscores the importance of early verbal interaction. Early language exposure and verbal attention are crucial for early childhood development and language acquisition. Data show that children who are exposed to a higher number of words daily tends to have better intellectual skills, on average. The following section of this article examines the benefits of talking to your baby and the effects of doing so on the baby’s brain development.
Benefits of Talking to Babies
Talking to babies is an essential part of healthy brain development. It provides social interaction and emotional attachment that babies need to grow and develop into healthy adults. As infants continue to hear language through their first years, they start to internalize the sounds and patterns of language to develop their own. Here are some benefits of talking to your baby.
– It promotes early language acquisition
Studies have shown that language development can be predicted by considering the number of words that a child hears before they reach three years old. The more a child hears, the better their language development, and they tend to have higher IQ scores. Vocabulary can also be easily developed through storytelling and shared reading.
– It improves cognitive function
When parents verbally interact with their children, they enhance their cognitive function. This verbal interaction assists children in developing strong problem-solving skills and memory retention.
– It facilitates emotional and social development
When parents talk to their children, they provide input that their babies require to understand, explore, and make sense of the environment around them. It provides caregivers with an opportunity to establish emotional connections with their babies, and emotional attachment, which is essential for healthy emotional and social development.
– It enhances developmental skills
Talking to babies gives them a head start in developing the skills they need to build social and receptive language skills necessary for school readiness. By the time babies reach 18 months of age, they have the vocabulary they require to understand instructional language and develop social skills to interact better with peers.
Conclusion
In conclusion, talking to babies is an essential part of healthy brain development, and studies have shown the importance of early verbal interaction for cognitive and emotional development. Parents who verbalize with their children regularly enhance their baby’s language skills and cognitive abilities, which are crucial to their success in school and beyond. Therefore, talking to your baby is an inexpensive, yet valuable investment that all parents should make.
Summary: A team of researchers led by Dr. Meghan Swanson, an assistant professor of psychology in the School of Brain and Behavioral Sciences at the University of Texas at Dallas, has discovered that parents who talk more to their babies improve their baby’s brain development. The researchers used MRIs and audio recordings to study the impact of caregiver speech on infant brain development. The study found that babies who heard more words had lower fractional anisotropy values, indicating that their white matter structure was developing more slowly. However, the children with slower white matter maturation went on to have better linguistic performance when they began to speak.

The Importance of Talking to Your Baby and Tips for Talking to Babies to Boost Their Brain Development
Every parent wants their child to have the best possible start in life. Talking to your baby is one of the most affordable and effective ways to create a strong foundation that supports your child’s development for life. Here are some tips for talking to babies to boost their brain development.
Talk to your baby all the time
Babies don’t need to understand the words you are saying to respond to them. Even if your baby is too young to understand what you’re saying, they’re listening and trying to process the sounds they hear. Therefore, talk to your baby whenever you have a chance, about anything that comes to your mind, including descriptions of things you’re doing throughout your day, upcoming events, or memories from your past.
Use a higher-pitched voice
Babies respond better to high-pitched voices. When you talk to them using a sing-song voice, it captures their attention and keeps them engaged in the conversation. Your baby will respond with laughter and coos, leading to a delightful experience that strengthens your bond.
Use exaggerated facial expressions
Babies are drawn to faces and love to mimic the facial expressions of their caregivers. When you’re talking to your baby, ensure you’re making eye contact with them. Use exaggerated expressions, such as furrowing your brows or smiling, to encourage your baby’s engagement. This interaction will help your baby develop their emotional and social skills.
Identify Objects and Describe Them
As your baby becomes more attentive and curious, use naming techniques to identify different objects in the environment. For instance, while taking a walk, you can name the different plants or trees you come across. This identification and description technique will help your baby develop their vocabulary, and enriches their communication skills.
Read with your Baby
Reading, especially picture and storybooks, is an excellent way to expose babies to new and diverse vocabulary. Reading regularly with babies can enhance their cognitive, language, and listening skills, as it helps them develop their imagination, creativity and vocabulary.
Final Thoughts
Talking to your baby is an essential part of developing a strong and healthy bond between you and your child. Apart from the emotional aspect, verbal interaction helps foster healthy cognitive, social, and emotional development, which supports a baby’s growth into a healthy adult. Therefore, talking to babies regularly is essential for healthy development, and parents should take advantage of it.

A team led by a neurodevelopmental researcher at the University of Texas at Dallas has uncovered some of the most conclusive evidence yet that parents who talk more to their babies improve their babies’ brain development.
The researchers used MRIs and audio recordings to show that caregiver speech is associated with infant brain development in ways that enhance language progress over the long term. Dr. Meghan Swanson, an assistant professor of psychology in the School of Brain and Behavioral Sciences, is the corresponding author of the study, which was published online April 11 and in the June 2019 print issue. Developmental Cognitive Neuroscience.
“This paper is a step toward understanding why children who hear more words have better language skills, and what process facilitates that mechanism,” Swanson said. “Ours is one of two new papers that are the first to show links between caregiver speech and how the brain’s white matter develops.”
White matter in the brain facilitates communication between various gray matter regions, where information processing takes place in the brain.
The research included 52 infants from the Infant Brain Imaging Study (IBIS), a project of the Center of Excellence for Autism funded by the National Institutes of Health involving eight universities in the US and Canada and clinical sites in Seattle, Philadelphia, St. Louis, Minneapolis, and Chapel Hill, North Carolina. Home language recordings were collected when the children were 9 months old and again six months later, and MRIs were performed at 3 months and 6 months, and at ages 1 and 2.
“This home recording moment was chosen because it straddles the emergence of words,” Swanson said. “We wanted to capture both this pre-linguistic, babbling time frame and a point after or near the emergence of speech.”
It has long been known that an infant’s home environment, especially the quality of the caregiver’s speech, directly influences language acquisition, but the mechanisms behind this remain unclear. Swanson’s team imaged various areas of the brain’s white matter, focusing on developing neurological pathways.
“The arcuate fasciculus is the fiber tract that everyone learns about in neurobiology courses and is essential for producing and understanding language, but that finding is based on adult brains,” Swanson said. “In these children, we also saw other potentially significant fiber tracts, including the uncinate fasciculus, which has been linked to learning and memory.”
The researchers used the images to measure fractional anisotropy (FA). This metric for the freedom or restriction of water movement in the brain is used as an indicator of the progress of white matter development.
“As a fiber track matures, water movement becomes more restricted and brain structure becomes more coherent,” Swanson said. “Because babies are not born with highly specialized brains, one might expect the networks that support a given cognitive ability to start out more diffuse and then become more specialized.”
Swanson’s team found that babies who heard more words had lower FA values, indicating that their white matter structure was developing more slowly. The children went on to have better linguistic performance when they began to speak.
The study results align with other recent research showing that slower white matter maturation confers a cognitive advantage.
“As the brain matures, it becomes less plastic: networks settle into place. But from a neurobiological point of view, childhood is unlike any other time. A baby’s brain seems to depend on a prolonged period of plasticity to learn certain skills,” Swanson said. “The results show a clear and striking negative association between FA and childhood vocalization.”
Sharnya Govindaraj, co-author of the paper, a doctoral student in cognition and neuroscience and a member of Swanson’s Baby Brain Lab, said she was initially surprised by the results.
“Initially we didn’t know how to interpret these negative associations that seemed very counterintuitive. The whole concept of neuroplasticity and absorbing new knowledge had to fall into place,” he said. “What ability we’re seeing is also very important, because something like vision matures long before language.”
As the parent of a young child in a bilingual home, Swanson was curious about how this relationship works for babies exposed to more than one language.
“Raising a bilingual girl, it’s remarkable how she doesn’t get confused by languages and knows who she can use which language with,” Swanson said.
Swanson said she has also gained a deeper level of appreciation and gratitude for what she, as a researcher, asks parents to do in her studies.
“When participants sign up, I ask them to commit to a year and a half,” he said. “Because of the commitment of all parents in previous studies, I and others have the knowledge that allows us to communicate with our children in a way that supports their development.”
Swanson said the bottom line is that parents have the power to help their children develop.
“This work highlights fathers as change agents in their children’s lives, with the potential to have enormous protective effects,” Swanson said. “I hope that our work equips parents with the knowledge and skills to support their children to the best of their ability.”
