Children Better Prepared for School If their Parents Read Aloud to Them

Young children whose parents read aloud to them have better language and literacy skills when they go to school, according to a review published online ahead of print in the Archives of Disease in Childhood.

Children who have been read aloud to are also more likely to develop a love of reading, which can be even more important than the head start in language and literacy. And the advantages they gain persist, with children who start out as poor readers in their first year of school likely to remain so.

In addition, describing pictures in the book, explaining the meaning of the story, and encouraging the child to talk about what has been read to them and to ask questions can improve their understanding of the world and their social skills.

The review brings together a wide range of published research on the benefits of reading aloud to children. It also includes evidence that middle class parents are more likely to read to their children than poorer families.

The authors explain that the style of reading has more impact on children’s early language and literacy development than the frequency of reading aloud. Middle class parents tend to use a more interactive style, making connections to the child’s own experience or real world, explaining new words and the motivations of the characters, while working class parents tend to focus more on labelling and describing pictures. These differences in reading styles can impact on children’s development of language and literacy-related skills.

The Reach Out and Read programme in Boston has improved the language skills of children in low income families by increasing the proportion of parents reading to their children.

The programme provides books and advice to the parents about the importance of reading aloud. Parents who have been given books were four times more likely to say they had looked at books with their children or that looking at books was one of their child’s favourite activities, and twice as likely to read aloud to their children at least three times a week.

Depressed Fathers ‘Hit Learning’

Children whose fathers are depressed have smaller vocabularies than those who do not, a US study suggests.

But the Eastern Virginia Medical School study of 5,000 families found language development in children whose mothers had similar symptoms seemed unaffected.

Researchers said by the age of two, children with depressed fathers used 1.5 fewer words than the average of 29.

This could be because depressed fathers spent less time reading to their children, they wrote in New Scientist.

The researchers, led by paediatric psychologist James Paulson, surveyed about 5,000 families.

When the children were nine months old, 14% of the mothers and 10% of the fathers were clinically depressed.

The researchers assessed the impact on language development by measuring what proportion of 50 common words the children were using at two years of age.

On average the children in the study were using 29 of the 50 words by the time they reached two.

‘Significant difference’

However, those children whose fathers were depressed when they were nine months old used an average of 1.5 fewer words than those whose fathers were fine.

Dr Paulson said the difference might seem small, but when scaled up across a child’s complete vocabulary it might make a significant difference.

In contrast, there was no difference in the size of the vocabulary of children whose mothers were depressed, and of those whose mothers were not.

The researchers found that depressed mothers did not reduce the amount of time they spent reading to their nine-month-old baby, but depressed fathers read on average 9% less than those who had no problem.

Dr Paulson, who presented the findings to a meeting of the American Psychiatric Association, said he hoped the study would encourage depressed fathers to seek help.

He said: “Men may not be likely to seek help for themselves but when other people who depend on them become affected, that may change the landscape.”

Ruth Coppard, a psychologist with an interest in child development, said depressed people tended to withdraw and go quiet, but that women often had no choice, but to continue with child care duties regardless.

Too Much TV for Babies Means Less Verbal Interaction with Mum

Over the last decade or so there has been mounting concern about the effect of television and videos on young children.

A huge increase in television programmes now available which are particularly aimed at young infants has occurred, despite warnings from experts that children younger than 2 years should not watch any television at all.

Along with the plethora of such programmes has come more and more evidence of the potential adverse effects of television exposure on young children.

Researchers in the U.S. are now saying because infants in low-income families are watching television or videos, with a supposedly ‘educational’ basis, their mothers rarely speak to them.

The study by researchers from New York University School of Medicine also suggests that the potential benefits from educational media may be limited.

Lead author Dr. Alan L. Mendelsohn says many of the programmes marketed as educational have limited data to support such claims and these claims were even less so if no co-viewing with a parent took place.

Dr. Mendelsohn and his colleagues set out to measure the verbal interaction between mother and infants associated with media exposure and maternal co-viewing; to do so they carried out an analysis of 154 low socio-economic status mothers-infant pairs who were taking part in a long-term study on early child development.

It was revealed that over one 24-hour period, 149 of 154 mothers reported that their 6-month-old infants had a total of 426 exposures to television or videos.

These included 139 exposures to educational programs for young children; 46 to non-educational programs for young children; 205 to programs for school-aged children, teenagers or adults; and 36 to unknown programs.

The researchers found that of those 426 television and video exposures, mothers talked to their infants during only 101 of them.

They say their findings support their hypothesis that interactions were most commonly reported in association with educational content, especially programs that had been co-viewed; however half of the exposures consisted of programs not intended for young children.

Even when they were intended for young children they did not involve frequent interactions when they were co-viewed.

The researchers say the findings are important, because parent-infant interactions are associated with long-term developmental-behavioural outcomes and they say verbal exchanges happen more often with reading and playing with toys.

The researchers say given the large amount of media exposure and low verbal interaction, more research is called for to determine whether such media exposure is of benefit to young children.

They say programs with educational content were no more likely to be co-viewed than were other programs and the research does not support the development of infant-directed educational programmes on the basis that they increase co-viewing and interaction.

The study is published in the current issue of the Archives of Pediatrics & Internal Medicine.

Research Sparks Push for Earlier Schooling

A tide of recent research on early childhood development is inspiring prominent scientists and politicians to argue for an unprecedented investment in schooling that begins virtually at birth.

But as decades of academic studies on brain development start to land in the real world, experts are divided on whether to focus new funding on infants and toddlers, or conventional preschool. Many now think some policies popular with politicians and the public, such as universal prekindergarten, may fail to reach at-risk kids at a young enough age.

The scientific controversy also is spilling into the presidential contest, where the Democratic candidates have taken divergent positions on universal preschool and other early childhood issues.

Studies have suggested that intervening before children start preschool improves academic outcomes for low-income kids and may reduce the risk that they will end up in prison. Such interventions stem from the theory that experiences in the first five years of life set a lifelong course for brain development.

Chicago has become a national proving ground for schooling during the first three years and is home to prominent advocates such as Nobel Prize-winning economist James Heckman of the University of Chicago, who said reaching kids before preschool could offer the best long-term economic return.

Even at age 4 or 5, you may be starting too late,” Heckman said. “I wouldn’t say it’s hopeless to help kids after those early years, but it’s extremely expensive.”

Backers of universal preschool say the evidence for even earlier intervention is not yet solid and offering conventional prekindergarten to everyone would help build popular support for early education.

In theory, starting to intervene soon after birth should help kids more because that’s when experience starts to shape their brains, many experts said.

Children’s brains change more between conception and kindergarten than at any other time. University of Chicago neuroscientist Peter Huttenlocher showed in studies over the last 30 years that connections between cells in most brain areas peak by age 3, then decline gradually as experiences mold the brain’s circuitry.

The zero-to-3 period is not necessarily a magical and irreplaceable window for teaching children. But studies show that babies raised in poverty get fewer of the early experiences that spur vocabulary growth and good social judgment, making it harder for them to catch up later.

For example, toddlers whose parents speak more words to them develop bigger vocabularies than children who hear less speech, studies have found. One University of Kansas study concluded that kids from upper-income backgrounds hear 30 million more words by age 3 than those from poor families.

Early intervention with enrichment programs can narrow that gap, researchers and advocates say.

“The basic science of brain development says you need to start as early as possible for kids in the greatest danger to get the best outcomes,” said Jack Shonkoff, director of the Center on the Developing Child at Harvard University.

Bruce Fuller, a professor of education and public policy at the University of California-Berkeley, said he feared focusing on universal prekindergarten — making preschool a middle-class entitlement — could divert help from low-income families that need it most.

“Why would we use scarce public dollars to subsidize all families if we know the biggest impact is with poor kids?” he said.

Five Things New Parents Need to Know

Parents have some homework to do, according to new findings presented at the Pediatric American Society meeting in Honolulu, Hawaii, this weekend.

The research shows that 31% of U.S. parents know very little about the pace of a typical infant’s development, whether it’s when a child should start talking or begin potty training. The data is based on an analysis of the Early Childhood Longitudinal Study’s Birth Cohort, a nationally representative sample of more than 10,000 9-month-old babies and their primary caregivers. Parents were asked to answer 11 questions, where those who got four or fewer correct were considered to have low-level knowledge.

While it may not sound like a big deal, experts say that this lack of knowledge can negatively affect parents’ interactions with their babies.

We asked study author Dr. Heather Paradis, a fellow in pediatrics at the University of Rochester Medical Center, why so many parents don’t know what to expect after expecting and what they need to know about their babies’ development.

Why do so many parents lack knowledge about infant development?

I think that parents get parenting information from a variety of sources, from reading magazines and books … most importantly, parents look for information from their child’s doctors.

There’s a lot of information that’s out there about what to expect when people are pregnant, but I don’t know that there is quite as much information on what to expect about how your child grows and develops in the first years of life, and there’s a tremendous amount of change. This study was surprising in just how many parents don’t have knowledge of normal infant development.

Do you have a sense as to whether this is a new trend?

I think that a lot of emphasis in the past has been placed maybe on what we would call “high-risk” parents–those with a lower education, lower socioeconomic status. But one of the surprising things that this study showed is that it’s not only those parents we should be targeting, but it’s something we should expand to the general population of parents. Everyone could benefit.

What was one of the most surprising things the study revealed in terms of parents’ confusion?

The most surprising thing to me was not necessarily what knowledge they did or didn’t have, but how that knowledge translated into actual behavior, or observed interaction with the child. That connection is something lacking in previous studies. This study showed that parents who have higher knowledge of normal infant development were shown to have higher (quality) observed interactions with their children.

The other thing is that we looked at not only parent/child interaction but parents’ reports of frequency of what I would call enrichment activities, such as reading books with a child, singing songs. We know early enrichment activities with kids leads to higher IQs, earlier reading, better school preparation. The parents with the higher knowledge of normal infant development also had a significantly higher reported frequency of doing those enrichment activities with their kids.

What are the potential negatives?

Parents who have unrealistic expectations could misinterpret a child’s normal behavior and could respond inappropriately. An example would be like a mom who expects an 18-month-old child to sit still during an appointment. Eighteen-month-olds are normally curious. I would expect them to be wandering around the room. If parents are expecting a child to sit still on a chair for an entire appointment, they may take normal curiosity and interpret it as intentional defiance, rather than the normal curiosity it is. That could lead to inappropriate harsh discipline or the withdrawal of affection.

I think quite often parents maybe underestimate a child’s ability to pick up language skills. A lot of parents don’t think that it’s worthwhile to read a book to their infant, to their 2-month-old, and they definitely should be doing that, even if it’s to look at pictures and let the child hear the normal qualities of voice. They might not understand the words the parent is saying but they definitely understand what’s going on and the interaction going on between the two of them.

How should parents go about educating themselves?

Certainly, I think it’s an opportunity for pediatricians that, even during our brief office encounters with parents, we can potentially do something that can have a large impact on the way that parents and children interact. I do think that getting information from reputable sources, asking a child’s doctor for recommendations on books and Web sites to get high-quality information, is something parents could do.

Pay Parents to Stay at Home, Says School Head

Parents should be paid to spend time with their children to stop toddlers as young as two being sent to schools and nurseries, a leading head teacher has said.

Clarissa Williams, the new president of the National Association of Head Teachers, said that parents were being separated from their children too early.

Why do we feel the need to send children into an education environment at the age of two? Are parents so distrusted that we want to separate them from their children at the earliest opportunity?” asked Ms Williams, the head of Tolworth Girls School in Surrey.

Speaking at the NHT annual conference in Liverpool, the head said parents should be rewarded financially for staying at home, playing with their children, reading to them and bringing them up well.

“There needs to be a contract between the receiver of the benefits that if they stay at home to do quality things with their children, they will be rewarded.

Lots of mothers stay at home and deal with a single income and we should respect that.

Ms Williams said some young children reacted badly to intuitional settings, echoing research that suggests that putting toddlers in nurseries for a long amount of time can lead to aggression.

Lots of children react well to nurseries, others are more anxious and that manifests itself in their behaviour, said Ms Williams.

The head suggested that child allowance as well as benefits should reflect the effort parents put in with their children.

The proportion of working mothers has risen steadily over the last decade.

Thousands of babies are now looked after by nurseries. Government vouchers giving free child care places to 3 and four year olds have also led to a rise in the number of children in pre-school settings.

Children in the UK also start formal education at age 5, much earlier than the rest of Europe where 6 or 7 is the norm.

In her speech Ms Williams also criticised school admissions.

She said choice was limited “mostly to those able to exercise it.” She suggested that allocating secondary school places by lottery could be fairer.

The controversial distribution of school places by ballot has been adopted by Brighton and Hove, several schools in Hertfordshire and a few in London.

Mums Can Improve Kids Academic Performance by Reading

Mums can improve their kids academic performance by encouraging them to read more, says an expert.

Sharon Darling, president and founder of the National Centre for Family Literacy has suggested that incorporating a daily reading habit is essential for childrens future academic success.

Many moms wonder what they can do to help their children be successful in school. The answer is surprisingly simple, said Darling.

Many of the things parents do with their children as they work, play, read and talk together have an impact on the skills needed to become a confident and competent student.

Singing songs, making up silly rhymes, talking about what you see, pointing out letters and words in the environment and reading together are just a few activities parents can do, she added.

Parents can support their childrens learning with talking at the dinner table, playing games together, sharing household chores or while riding in the car.

It could also be done by making reading a daily habit of the family. Everyone should have a library card and teach children that reading is fun.

Creating reading rituals by setting aside a special time and place every day so that they enjoy stories without interruptions.

Moreover, cuddling closely with your child to foster a sense of security can actually eliminate stress that scientists believe produce hormones, which blocks learning.

Mealtimes can be the best opportunity to enhance learning skills.
Various programs have shown success in incorporating mealtime with literacy. In Southern California, the McDonalds Family Mealtime Literacy Nights have resulted in parents using its strategies and materials at home to improve literacy skills.

You can talk to your kids while driving across town or on vacation and looking for signs with words that begin with the same letters as childs name. Each person remembers what the other items were and adds an item that begins with the next letter of the alphabet.

Make up rhymes using words or items you see as you drive along or alliteration statements where all the words begin with the same sound. See how long you can keep the rhyme or alliteration statement going; and

Use techniques for reading that have been proven to increase effectiveness in reading time, providing sound effects to capture their attention, making connections between the spoken and written word because hearing sounds in words is a basic skill needed for reading, talking about the story to reinforce comprehension and memory skills and reading again and again as it helps children recognize and remember words.

Study Captures Brain’s Activity Processing Speech

Research is First to Describe How Neurons Interpret Different Words

You might be able to hear the difference, but to many children and adults, these words sound exactly the same. The problem isn’t that they can’t hear the sounds. The problem is that they can’t tell them apart.

One in 20 children in kindergarten has difficulties understanding speech that are not related to hearing or problems with their ears. The reason is that speech discrimination is a problem solved in the brain, not in the ear. How does the brain process speech sounds? Very little was known, until now.

Enter Dr. Michael Kilgard and Crystal Engineer. Kilgard is a neuroscientist in the School of Behavioral and Brain Sciences at the University of Texas at Dallas. His lab is one of the few in the world that studies how individual neurons process speech stimuli. Engineer is one of Professor Kilgard’s doctoral students. Together they conducted a study to provide the first-ever description of how speech sounds are processed by neurons in the brain. This insight may offer a new approach to treating children with speech processing disorders.

Now that we’ve cracked the door on this important problem, we should be able to understand the neural basis of many common speech processing disorders and use this information to develop new treatments,” said Dr. Kilgard.

The study is part of Engineer’s dissertation, “Cortical activity patterns predict speech discrimination ability,” and will be published in the May issue of Nature Neuroscience, the top research journal in the field of neuroscience. The advance, online publication of the study is now available on the Nature Neuroscience Web site.

This research is groundbreaking for a number of reasons. Prior studies have used a synthetic voice and tested the response to only a few words. Engineer and Kilgard had a much broader scope. They tested all the consonant sounds in the English language using a human voice. Microelectrodes inserted into a rat’s auditory cortex enabled the researchers to capture the patterns of neural activity generated by each consonant with incredible precision. Recording techniques that can be used with human subjects (such as MRI and EEG) lack the precision to track the activity of individual neurons.

The recordings showed that contrary to prior belief it’s not the quantity of neurons that fire in response to a speech sound that is important. It is which neurons are firing and exactly when they are firing – down to the millisecond – that is critical.

Based on the patterns of activity shown in the neural recordings, Kilgard and Engineer believed they could predict the rats’ ability to discriminate the speech sounds. They hypothesized that speech sounds that generate similar patterns of neural activity would be impossible for the brain, and thus the rat, to tell apart. In contrast, speech sounds that generate dissimilar patterns would be easy for rats to tell apart.

To test their theory, they trained rats to press a lever in response to some speech sounds and not others. Although rats can’t talk and certainly don’t have language, the new study reveals that rats can easily hear the difference between most speech sounds. The auditory system in rats and many other animals are surprisingly similar to humans’.

For example, the neural responses for the words dad and sad are very different. (See video.) As expected, rats can easily distinguish between these two words. The neural responses for the words rad and lad are very similar. Not surprisingly, rats, like many children, find it very difficult to differentiate between these two words.

The neural patterns explain the rats’ ability to differentiate between different speech sounds. “Our study is the first to tie the perception of speech sounds to the neural response of the same sounds,” said Engineer.

So, they’ve cracked the code, now what? The implications are huge. The perception of speech sounds is important because these are the acoustic building blocks of language. Scientists couldn’t begin to isolate the problems with speech and hearing disorders until they understood how speech sounds are normally processed in the brain.

Already, one of the most cited researchers in the world on neuroplasticity, the brain’s ability to change, Kilgard has big plans for his UT Dallas students and lab. He not only tackles ambitious topics in neuroscience, but in the process, he creates hands-on opportunities for his students at every level to get involved. This is what inspired Engineer to pursue her Ph.D.

“Dr. Kilgard encourages undergraduates to follow their interests. They have the rare opportunity to initiate and run their own projects and publish in prestigious journals. If it weren’t for these opportunities, I wouldn’t have gone on to graduate school,” said Engineer. She has worked with Kilgard since 2003, as an undergraduate, and expects to complete her Ph.D in August.

The emphasis on student involvement is illustrated by the number and diversity of the authors listed on the Nature Neuroscience study. Engineer and Kilgard’s research team included master’s students Claudia Perez and Helen Chen; undergraduates Ryan Carraway and Kevin Chang; and Ph.D. students Amanda Reed, Jai Shetake and Vikram Jakkamsetti.

“This paper in Nature Neuroscience is a great testimony to the level of graduate education students receive at UT Dallas. Dr. Kilgard is a wonderful mentor who helps students develop into independent researchers,” said Dr. Bert Moore, dean of the School of Behavioral and Brain Sciences. “We are proud of both Crystal and Mike for this exciting research.”

Guide Child to Manage Emotions, Word Use

Q: My almost 5-year-old daughter occasionally does a Dr. Jekyll and Mr. Hyde thing, sweet and cooperative, then terrible and tantruming.

If I, my son or husband don’t tell a story just right, don’t understand what she’s saying, or we simply can’t hear her, she will scrunch her face in disgust, stomp her feet and say, “I hate you,” “Go away” or “You’re stupid.”

I’m not sure how to react. If I tell her to go to her room she freaks out — usually screams and fights further. Usually I just walk away and let her cry and get over it. But I feel like I’m “allowing” her to say these horrible things. Any ideas?

A: Parents today seem to be raising children who speak freely, expressing their ideas and feelings. The “seen but not heard” generation disappeared long ago. Kids today are seen and heard, sometimes over and above their parents. Some children like yours are able to control the emotional thermometer in the family. If they’re mad, sad, happy or frustrated, the entire household feels it.

Children blurt out shocking words mainly because doing so gets everyone’s attention and because they have limited language skills to say in a refined way what’s on their minds. Then, unfortunately, it becomes a part of their behavior repertoire; an unfortunate habit.

While it’s fine for children to express their ideas and feelings, parents hope that their children will learn to do so in a way that’s respectful. Your task is to teach your child to manage her emotions and refine her language skills.

So when you are telling a story and to your daughter’s mind you’re not telling it just right, and she gets emotional, yelling “I hate you,” say what would be appropriate in this situation and include a line about her emotions, “You’re frustrated that I forgot the part of the story about the dog barking.” By doing so you’re providing her with words to communicate respectfully her feelings about not hearing the story as she expected.

You can also add, “You’re angry that I forgot the part about the barking dog, but I know that you don’t hate me. It’s not OK to say ‘hate.’ ”

If your daughter says “go away” when you don’t understand her, again say what would be appropriate in that situation. Something like, “You’re frustrated when I can’t understand you. Please say what you said again.” Therefore, in time, your daughter will learn to say, “I get frustrated when you don’t understand me.”

It’s also important to include, “It’s not OK to tell me to go away. I know that you really don’t want me to leave.”

If you can’t hear what your daughter says and she screams and stomps while saying “You’re stupid,” say for her what would be appropriate: “You’re frustrated because I can’t hear you.” In time she’ll be able to say, “I get so frustrated when people can’t hear me.”

It’s also important to add, “I’m not stupid, and it’s not OK to say so to me or anyone.”

Here are additional lines that parents can use when children speak disrespectfully:

“Please say that again but in a way that’s nice and respectful.”

“That’s disrespectful talk. In our family, it’s not allowed.”

“I’m willing to discuss that topic with you but not when you’re out of control and speaking disrespectfully. The conversation is over for me.”

Most important, speak to your children modeling respectful language. Children are mimics. They copy language that is both hurtful and helpful, kind and unkind. While you can’t control the language that children pick up at school and in the media, you can model respectful language that’s used and expected at home.

A final note: When children are emotional, isolating them often makes the child’s emotional state escalate. Therefore, stay near your child when she is distraught with emotion.

Impairments in Language Development Can Be Detected in Infants as Young as 3 Months Old

Uncover how the brains of infants distinguish differences in sounds and it may become possible to correct language problems even before children start to speak, sparing them the difficulties that come from struggling with language.

New studies conducted by Professor of Neuroscience April Benasich and her Infancy Studies Laboratory at Rutgers University in Newark are revealing new and exciting clues about how infant brains begin to acquire language and paving the way for correcting language difficulties at a time when the brain is most able to change.

Benasich and her lab were the first to determine that how efficiently a baby processes differences between rapidly occurring sounds is the best predictor of future language problems. Using methods developed by Benasich and her lab, it can be determined as early as three to six months whether a baby will struggle with language development.

Benasich’s research is now focused on uncovering in specific detail how the developing brain processes and distinguishes acoustic differences that arrive in rapid succession. The ability to differentiate those sounds, such as the difference between “ba” and “da,” is critically important because decoding language requires us to process tiny auditory differences occurring as quickly as 40 milliseconds. During the first months of life, the baby’s developing brain also is involved in constructing an acoustic map of the sounds of his or her native language. That map allows the baby to efficiently acquire language. Apparently, however, in some infants the process seems to go awry.

About 5 to 10 percent of all children beginning school are estimated to have language-learning impairments (LLI) leading to reading, speaking and comprehension problems, according to Benasich. In families with a history of LLI, 40 to 50 percent of children are likely to have a similar problem. Many of these children go on to develop dyslexia.

Using several novel methods, including dense array EEG/ERP recordings, Benasich and her lab are able to analyze EEG, ERPs and the proportion of gamma power in infant brains. The dense sensor array allows the researchers to gently measure a full range of brain activity. Those measurements are obtained by placing a soft bonnet of sensors, resembling a hairnet with lots of little sponges, on a baby’s head and then having the infant listen to different series of rapid tone sequences.

We are finding that children who have difficulty processing rapid auditory input are not just showing a simple maturational lag, but are actually processing incoming acoustic information differently,” says Benasich.

Specifically, the research shows that babies who struggle with rapid auditory processing appear to be using different brain areas (as shown by neural patterns) and perhaps different analysis strategies to accomplish that task than children who do not have such difficulties. Included among their initial findings, the researchers have found less left hemisphere activity in the brains of children who struggle with rapid auditory processing as compared with matched control children. By pinpointing the exact differences in how the brain handles incoming acoustic information, it may become possible to guide the brains of babies at risk of developing language problems to work more efficiently before the children even begin to speak.

We can predict with about 90 percent accuracy what a baby’s language capabilities will be just by their response to tones,” says Benasich. “Our hope now is that we will be able to gently guide the brains of infants who are at the highest risk for language learning impairments to be more efficient processors so they can avoid the difficulties that result from struggling with language.”

To shed additional light on how inefficiencies in rapid auditory processing might be corrected, Benasich and her team have developed a Magnetic Resonance Imaging (MRI) protocol for scanning naturally sleeping healthy babies. This technique will allow better localization of active brain areas. To solve the challenge of imaging the brains of young children who typically are unable to lie still for extended periods in a scanner, Benasich’s team conducts the scans in the evening and asks the parents to go through their child’s normal bedtime routine, such as reading their infant a story, nursing them, rocking and snuggling. Once the child is asleep, headphones providing a steady stream of lullabies and an acoustic foam bonnet are placed on the baby’s head to reduce the sound of the MRI.

Our goal is not only to develop training techniques to correct rapid auditory processing problems, but to identify the period during infant development when the brain is most “plastic,” or most able to change through learning,” explains Benasich.

The lab’s work is funded by several sources, including grants from the Solomon Center for Neurodevelopmental Research, the Don and Linda Carter Foundation, the National Institute of Child Health and Human Development, and a new $460,000 grant from the Ellison Medical Foundation.
