Poverty in American Schools: What Educators Can Do

• January 17, 2012 by Norene Wiesen

 

Many children from poverty arrive in schools with a host disadvantages, including low self-esteem, unstable relationships, and brain differences.  But with support, encouragement and the right interventions, every child can maximize their ability to learn and succeed.

Learn more about "teaching with poverty in mind" in our on-demand webinar by Eric Jensen, full of actionable ideas for getting the most from learning time with students, building learning capacity, accelerating the learning process, and getting better buy-in from educators and students.

Creating Safe Learning Environments: How Classroom Management Influences Student Performance

• November 15, 2011 by Sherrelle Walker, M.A.

Think back to your grade school days. Did you ever experience a class where a bully ruled the roost? Were you ever bullied yourself?  Did you ever have a teacher who frightened you or who made you feel bad for underperforming? Or was there simply a disruptive class clown who constantly broke the classroom rhythm the teacher was trying so hard to create?

To varying degrees, all of the above situations can create what we might consider an unsafe learning environment. The teacher must take unquestionable ownership of the classroom, but do so in a positive, caring, constructive manner. The class succeeds or fails on his or her decisions and management of the entire learning experience.

Why is managing that classroom and creating that safe environment where learning can happen so essential? In her article on the value of safe learning environments, Lora Desautels, Ph.D., reminds us that during adolescence, the part of the brain that controls emotional responses—the amygdala—develops faster than other centers of the brain while the prefrontal cortex, a center for logical thought and rational response, develops later. Thus, our students are more effectively wired for emotion than logic. Their systems are primed to react to situations with feelings and they have not yet fully developed the ability to apply logical thinking to keep those feelings in check.

It follows that the stimuli within and surrounding the learning environment can have great effects on these emotional responses and can serve to either support or impair the learning process. The bully, the clown, and the teacher can all have a profound effect on how well a student learns.

So what can we as educators do to bring down the levels of stress in our classrooms and make sure that our learning environments are safe places where optimal learning can take place? How can we create spaces that keep the emotional responses as positive and free of stress and anxiety as possible so that we can most effectively engage fresh young minds?

Rebecca Alber has written a wonderful list of twenty ways to create a safe learning environment for Edutopia, which I highly recommend. Her advice for educators includes building community, setting clear boundaries, smiling and laughing a lot, and getting to know each individual student, as well as allowing them to get to know something personal about you. She says we should sit with our students. We should keep our expectations for student performance and behavior high. And we should incorporate art and music into the day.

I agree with Alber’s top twenty. I find it wonderful that she strikes a balance between creating a space that is fun and welcoming and full of laughter, but also one where expectations are set and failures become learning opportunities. All of them can do wonders when it comes to creating a space where students can let go of their stresses and anxieties and free their minds to absorb all the wonderful learning we have in store for them.

In the end, the responsibility for implementing these kinds of principles and removing the stressors that can impair learning lie with us, the educators. Creating that safe learning environment is a multifaceted challenge that, when done well, allows students to flourish.

Toddler Vocabulary Development: Shopping With Your Child

• October 11, 2011 by Martha Burns, Ph.D

There is no better time to teach your toddler the names of things than when you go out shopping together. The wonderful thing about shopping with your child at a grocery store or clothing store is that he can sit in a shopping cart and interact with you while pointing to all the interesting colors, shapes and objects around him.

Never mind that as he gets closer to two years old he may want you to focus on the candy aisle, or buy everything fuzzy or toy-like.  Use the time to provide names for all the wonderful objects you can see.

 “Wow!  Look at these oranges today—they are so big. They look like big balls don’t they?”

“Hey, those peppers are green and red and yellow, just like Christmas lights—what fun!”

“I see blue shirts and white shirts. What color do you like?”

As you talk about all the shapes and colors, your tot will begin to want you to tell him more names. If he can’t ask you “What is that?” yet, he will start to point to objects he wants you to name or let him touch. (Of course you don’t want him touching fresh food items or knocking down items on shelves, but there is no harm in letting him feel a soft cloth or looking more closely at the funny picture on a box of cereal.)

Here are some tips for making shopping both fun and educational for your child:

• Color, shape, and size: Notice colors, shapes, and sizes as you shop the fruit and vegetable aisle with your toddler. Tell your child that bananas are “long and yellow,” and that oranges, apples, limes and lemons look like “orange, red, green and yellow balls.” At the clothing store, “big pants” may be for “big daddy” and tiny shoes may be “just the right size” for your child.
• Texture and touch:  Clothing stores are all about touch. PJ’s are usually “soft,” and raincoats are “smooth and stiff,” while some coats may be “furry.” Your child will love feeling all the different textures.
• Questions: Note that celery has “leaves” and broccoli has “flowers.” Ask questions, “Why do you think cauliflower is named that way?” Point out that potatoes have “eyes” and wonder aloud, “Why do they have so many and we have only two?”
• My shopping cart: Some grocery stores have begun offering small grocery carts for young children to push around. You may want to wait until your tot is two or a little older, but it can be fun to let him choose apples, oranges or boxed cereals and push them in his own cart. At home you can use empty boxes to “play store” on a rainy day.

You might hear yourself saying, “not today” or “not now” as your child wants you to add everything to your basket (or his), but giving him the opportunity to explore the world around him is a valuable experience for both of you.  You get to cross a few items off your to-do list, while your toddler works on vocabulary development through conversation and play, with his favorite person—you.

Separating Brain Fact from Brain Fiction: Debunking a Few Neuroscience Myths

• September 1, 2011 by Bill Jenkins, Ph.D.

The brain is one of the most mysterious and misunderstood organs in the body. It represents the seat of our judgment, our senses, perceptions and our creativity.  More than any other aspect of our anatomy, the uniqueness of our brains is at the core of what makes us truly human.

While neuroscience advances every day, there are a number of myths about the brain that are accepted by many people as fact. As a scientist, I and my colleagues have worked to uncover the brain’s truths.  So what are some of these myths – and what are the true stories behind them to the best of our scientific knowledge?

Fiction: We use only a small percentage of our brains.

Fact: General thinking is that we use only about 10% of our brains. Nothing could be further from the truth. Brain scans such as MRI and PET scans show that we regularly use all parts of our brains. Certainly, different areas of the brain are activated during different types of tasks, and some parts of the brain are less critical to support vital functions than others. But as even small brain injuries can show, every part of the brain performs essential functions in how we process, communicate with, and move through the world around us. Read more at http://www.scientificamerican.com/article.cfm?id=do-we-really-use-only-10.

Fiction: The wrinkles on the surface of the brain appear and become more pronounced as we learn.

Fact: The ridges and crannies – more correctly, the gyri and sulci – on the surface of the brain actually all appear by the time a fetus is 40 weeks old. As the human brain evolved, gyri and sulci appeared as a result of the brain having to fold in upon itself as it grew larger to fit inside a correctly proportioned skull. While the gyri and sulci do not change as we learn, the brain itself – as we know from research in brain plasticity --  does continue to change throughout our lives.

Fiction: Brain damage is permanent.

This is an interesting myth, in that it is the result of ambiguous language. The brain is made up of a collection of neurons – brain cells – that are all networked together. When the brain suffers trauma and neurons are destroyed or damaged, those neurons cannot regenerate. In that sense, the damage to them is permanent. That said, those neurons are linked together at synapses to form complete networks. While a single neuron cannot be repaired, the pathways and connections throughout the brain can rewire themselves and form new pathways. If a connection is lost due to injury, we can reestablish that connection if the damage is not so acute that the entire network cannot be rewired. For a scholarly treatment of how the brain recovers from injury, see http://web.uvic.ca/~skelton/Teaching/General%20Readings/Robertson%20Murre%201999.pdf.

Fiction: A person is either “left-brained” or “right-brained.”

The theory goes that left-brained people are more logical and right-brained people are more creative. Certainly there are asymmetries associated with locations of certain brain functions. For example, mathematical computation and the grammar and vocabulary aspects of language seem to be controlled in most people in the left brain, while numerical approximation and comparison, along with interpretive aspects of language like prosody and intonation, appear to be controlled in the right.  These ideas date back to original research done in 1861 by French physician Pierre Paul Broca. Today, through MRI and PET imaging techniques, we have a much more complex view of the way the brain’s hemispheres control functions and interact with one another. The two perform a complex dance of information exchange that gives rise to our abilities. For a look at results of some of these MRI tests in children, see http://www.ncbi.nlm.nih.gov/pubmed/8780075.

Fiction: There are five senses: sight, smell, hearing, taste and touch.

These five are simply the ones that we are most aware of in our conscious minds, but we perceive and sense the world in a great many other ways. For example, “proprioconception” describes how our bodies are oriented in the world. “Nociception” is how we perceive pain. We sense changes in temperature. We sense balance. We feel thirst and hunger. We sense the passage of time. For a quick and easy description of the senses – in humans as well as other species – see http://en.wikipedia.org/wiki/Sense.

As scientists continue our search for the facts, there is much we don’t know; we are expanding our knowledge of the brain’s truths every day. As new discoveries are made, it is natural for facts to become distorted and reinterpreted with each new telling.   As educators and scientists, we should take the time to explain the truths about the brain and rectify any misunderstandings we may hear others repeat. The brain is amazing, and communicating the truths about it will further society’s understanding as a whole.

Still the Write Stuff: Why We Must Continue Teaching Handwriting

• August 23, 2011 by Sherrelle Walker, M.A.

When it comes to lost arts, we could argue that none is getting lost faster than handwriting. Since the personal computer and now the telephone have become the primary methods for recording our ideas, we simply do not write – I mean with an actual writing implement like a pen or pencil – as much as we used to.

So, we must ask ourselves, is this really a problem? Sure, one could argue that receiving a handwritten letter is more meaningful than getting one that is typed, but that’s an emotional opinion; it’s not a scientific argument. And aren’t professionals in all fields using more computers, tablets and handhelds to communicate, record and share ideas? So, what is the real value of learning handwriting skills versus being able to type 100 words per minute on a QWERTY keyboard?

At Indiana University, Dr. Karin Harman James, assistant professor in the department of psychological and brain sciences, focuses her research on how motor stimuli can influence our visual recognition, and how the brain changes as we have different experiences. This research provides a basis for a scientific argument for the continued instruction of handwriting.

In a 2008 study published in the Journal of Cognitive Science, adults were shown new characters as well as a mirror image of these characters after reproducing them through writing and keyboarding. When quizzed afterward, subjects were shown to have a “stronger, longer lasting recognition” of the characters’ correct orientation when they had written them by hand versus produced them by matching them to a keyboard button. This suggests that engaging the motor nerves to create the shapes by hand helped solidify the ability to identify such shapes.

In another study, James’ team took this idea to the next level to see what was actually going on inside the brain during these activities. They used a functional MRI to map brain activity in children as they looked at letters before and after letter-learning instruction. Their results showed that those who practiced writing the letters showed more brain activity than those who only looked at the letters. In addition, according to a 2010 report on the research in the Wall Street Journal Online, James said that after four weeks of training, the children who practiced writing skills showed brain activation similar to an adult’s.

Between these two studies, we see excellent examples of brain plasticity at work. James’ work demonstrates a clear connection between how engaging more of the brain in the activity of writing improves how letters are committed to memory. Given that letter recognition is an essential step for early readers, it’s easy to see why practicing writing letters is an essential component of the groundwork for later success.

Certainly, with limited time, schools try to maximize student achievement, and give them a baseline of skills that will allow them to continue to develop to optimize their success throughout life in an increasingly technology-based society. That said, based on James’ research, it’s quite clear that penmanship has an important place in the classroom, and not just as an important traditional skill.  In actually applying pen to paper, we allow our students to engage their brains in ways that typing on a keyboard cannot. And whether such an activity is done with pen and paper, a stylus and a tablet PC or chalk on a blackboard, it is in every student’s best interest to practice the “write” stuff.

Connecting the Dots Between Infant Temperament and Future Success

• August 18, 2011 by Martha Burns, Ph.D

What factors will ultimately determine a child’s ability to succeed in life? While measures like socioeconomic status might allow a child to start off on the right foot, current research is delving into the nature of temperament and how that affects a person’s ability to successfully navigate life’s many challenges.   If temperament is pre-determined, there’s not much a parent can do, but if nurture plays a role, then how can parents help their child have the best quality of life?

While temperament has long been thought of as something innate, recent research has demonstrated that only some aspects are genetic, while others are environmental.

On the genetic side, as any parent will agree, much of an individual’s personality manifests very early on in the infant’s life. Parents with more than one child often note that one of their children seems easygoing from day one, but another child is demanding. One child may be outgoing and social, while their sibling may be more shy or withdrawn.

As we consider how these seemingly innate traits develop, we cannot ignore the fact that the environment – from parental attention to nutrition – exerts a strong influence on a child’s personality development. Current research tells us that a pregnant mother’s iron levels can affect the disposition of her child. Emerging data gleaned from animal research indicates that the quality of maternal parenting styles, such as the way a mother nurses her infants or the amount of maternal grooming, affects the temperament of her offspring.

An interesting question arises: How do these early manifestations play out as the child matures? For example, will an infant who is able to self-calm herself in stressful situations by turning away from aversive stimuli or sucking her thumb, for example, continue to exhibit self-regulatory behaviors as she gets older?

Considering the interplay between innate versus cultivated aspects of temperament, what actions can a parent take to affect the development of a child’s personality to give that child the best chance at personal satisfaction, academic achievement and successful relationships later in life? As the above research – and our own parental gut instincts – suggest, we can set them up by providing:

• Excellent nutrition
• Logical, predictable rules for living with others
• Optimal environments and schedules for sleep
• Lots of interactive play with family and friends
• Less screen time
• Lots and lots of parental love and affection

 

With parents providing these positive factors for their children, every child – from shy to outgoing, from tense to easygoing – will have the best chance at developing a balanced temperament as they mature.

Building a Foundation for School Readiness for Low Income Children

• August 16, 2011 by Bill Jenkins, Ph.D.

As educators with experience in child development, we understand the essential nature of being responsive to a child. Children who do not receive enough attention do not develop in the same way as those who receive consistent nurturing and feedback. Research has demonstrated how, at a physiological level – their brains simply wire themselves differently as they develop. This deficit in early childhood experiences often manifests itself as developmental delays across a wide spectrum of behaviors. These behavioral delays appear in parallel with delays in brain development.

Imagine a child growing up in a home where sensitive, responsive caregiving is rare. Maybe mom and/or dad work more hours and are simply not available. Maybe they come home too tired to read or play or simply snuggle with the child. Or, this is an environment where sensitive, responsive nurturing is not valued very highly. While it is not the case in every situation like this, at its extreme, the parent or parents may be truly neglecting the child’s needs at this early stage. Even moderate differences in these important parent-child interactions have important longer-term consequences for development.

Research has shown that in these situations a child’s brain development quickly gets derailed. Children who do not receive enough of what is known as “sensitive-response caregiving” and cognitive stimulation do not develop executive function skills as readily as their counterparts in more caring, stimulating environments. (Lengua et al., 2007; Li-Grining, 2007) In other words, children may not be encouraged to be aware of and interact with the world around them (cognitive stimulation). They also may not be encouraged to engage or develop planning, decision-making or troubleshooting skills (executive function).

Executive functions, also known as “domain-general” functions, are those called upon in various types of learning opportunities; these include such functions as working memory, regulation of emotions and attentional control. On the other hand, a “domain-specific” cognitive process is one that represents a specific skill or skill area, such as reading or counting.

But what are the implications as children grow and enter school? Recently, a team of researchers led by Janet Welsh at Penn State studied readiness for school in a group of Head Start children and how certain cognitive processes were associated with the development of certain skills. Specifically, they studied the relationship between domain-general and domain-specific cognitive processes in these low-income pre-kindergartners, and tracked them through kindergarten.

Welsh‘s study showed that skills scaffolded consistently from one level to the next, and these skill levels represented good indicators of how well the child would develop the next set of skills. In other words, good working memory and attention control predicted the development of early literacy and numeracy skills, and these skills were predictors of later math and reading achievement.

Whether through experience in the home, great work in the pre-kindergarten classroom and/or support from computer-based learning exercises, it is clearly essential that we support the early development of domain-general cognitive skills as early and as strongly as possible.

While this may seem obvious, Welsh’s research underscores the essential nature of laying a foundation in those executive functions, those domain-general cognitive abilities, for each and every student – but especially for those at an economic disadvantage if we are to close the gaps and truly offer the same opportunities to every student.

Left vs. Right: What Your Brain Hemispheres Are Really Up To

• July 12, 2011 by Martha Burns, Ph.D

In the 1980’s, brain researchers viewed the two sides of the brain as dichotomously opposed: the right hemisphere was seen as a gestalt processor, good at “seeing the big picture,” while the left hemisphere was attributed with detail processing skills. Other views at that time attributed the left hemisphere with being more logical and analytical while the right hemisphere was considered more intuitive.^[i]

Some went so far as asserting that men and women exhibited different right vs. left preferences: men were attributed with stronger left hemisphere skills and women better right hemisphere skills. Although this male-female distinction was never empirically verified through research, the somewhat “pop-psychology” view that the right hemisphere is important for skills like music and art, predominated. In fact, there were books written instructing individuals on how to “draw with the right hemisphere” or how to “teach to the right hemisphere”.^[ii]

It now appears that some of these notions need to be revised.  A current view is that, for the majority of us, the right hemisphere is a pattern recognizer that may develop before the left. From this perspective, the right hemisphere enables a child to attend to and appreciate the gist of a sensory experience within each cognitive domain. For example, in acquisition of mathematical concepts, the right hemisphere may enable a young child to appreciate quantities in terms of more vs. less prior to assigning numerical values to the quantities (which would involve left hemisphere skills). There is research demonstrating that babies can discern a group of dots in terms of general aspects of quantity.^[iii]

Patricia Kuhl at University of Washington in Seattle has shown that typically developing infants show an interest in human voices over other environmental sounds like a car horn or doorbell, and direct their attention to human voice when it conveys information that is interesting.^[iv] Ultimately this may lead to an understanding of how the melody of a voice is used to convey a person’s intent.  In other words, recent research suggests that the right hemisphere may be best at processing patterns like voice contour, facial expression, aspects of size and quantity, gestalt aspects of the world which, from a developmental perspective, represent the way children begin to learn about cognitive areas like music, art, mathematics or language.

Considering the cognitive domain of music, for example, the right hemisphere appears to have a fundamental preference for recognizing melody, which allows a young infant to be interested in and ultimately reproduce early nursery songs. In the realm of visual processing, the right hemisphere has been shown to be better at perceiving the form or outline of an object than the details contained within the object.^[v]. And, similarly, although many people regard the left hemisphere as dominant for language, newer research has shown that the right hemisphere is superior at processing information like vocal inflection (prosody), and perhaps going directly from word to meaning, especially in very familiar phrases like idiomatic expressions (eg., “it is raining cats and dogs”) while the left hemisphere is more important for processing aspects of language that depend on analyzing the specific sequence of the sounds and words which are essential for understanding grammatical form of language and perceiving internal details of words.^[vi]

Several neuroscientists have accordingly revised and expanded the early right-left dichotomy to see the right hemisphere as preferential in processing form, structure, and perhaps, direct links to emotion,^[vii]  while the left hemisphere handles complex, rapidly changing stimuli, in which discerning the specific sequential order is critical to perception (as in speech perception, for example, where one must discern and order very rapidly changing complex acoustic events very quickly.)^[viii]

Another revision to the older view of right versus left hemisphere complements the view that the right hemisphere is preferential for pattern analysis, and comes from developmental neuroscience which has reported research that supports the contention that for most cognitive skills the right hemisphere matures before the left.^[ix] This certainly seems to the case when one looks at the early stages of neuronal development and migration in the fetal brain,^[x] and also the building of early axonal superhighways, as well as the research on myelination.^[xi] In fact, it may be that when this typical right to left maturation does not occur, developmental neurological abnormalities result. For example, there is some early research evidence that Autism Spectrum Disorders may represent one example of developmental deviations in this typical right-to-left developmental hierarchy.^[xii]

Although it may seem somewhat of a stretch from the early research in this area, one can observe how this organization might be reflected in early childhood development in the stages children pass through in the gradual mastery of skills. For example, when a child first begins to enjoy music, the observant adult notices that the child moves his or her whole body to the musical rhythm. For nursery songs, like “Twinkle Twinkle Little Star” the child often begins by humming the melodies. In both cases, this may represent right hemisphere processing.

In most cases, it will be a few years before the child will be able to read musical symbols which would presumably involve more left hemisphere skill. We do have research that shows that when three month old babies are first listening to oral language, the right hemisphere is much more active than the left.^[xiii] Patricia Kuhl has shown that mothers instinctively seem to match their speech to babies’ early developing perceptual preferences by exaggerating melodic inflection with young babies, probably reflecting their intuitive knowledge that they need to exaggerate the language cues (intonational contour and vocal inflection) that the right hemisphere seems to process preferentially while deemphasizing the production of the speech sounds themselves (left hemisphere preferences).^[xiv]

How Learning and Literacy Enhance Our Brains

• June 30, 2011 by Bill Jenkins, Ph.D.

Reading is a recent cultural invention. It is not a skill we are naturally programmed to develop like walking or vocalizing. It is a relatively recent development in human history estimated to be only about 6000 years old. The development of oral language in humans is believed to be nearly 300,000 years old.  Oral language is thought to have co-developed with the use of tools as both require complex motor control.

To quote from the recent book Reading in the Brain (Dehaene, 2009): "At this very moment, your brain is accomplishing an amazing feat­—reading. Four or five times per second, your gaze stops just long enough to recognize one or two words.  You are, of course, unaware of this jerky intake of information.  Only the sounds and meanings of the words reach your conscious mind.  But how can a few black marks projected onto your retina evoke an entire universe?"^[i]  

In 2010, Stanislas Dehaene, et al. published a study which evaluated whether learning to read improves brain function, and also whether there are tradeoffs for such learning.^[ii] In other words, does learning to read “occupy” a space in the brain that could or would be used for something else in our evolutionary past?

Dehaene and his research team have used functional magnetic resonance imaging (fMRI) to measure how the brain responded to various stimuli, including spoken and written language, visual faces, houses, tools, and checkers in a group of literate and illiterate adults. Ten were illiterate, 22 learned to read as adults, and 31 learned to read as children.

In the end, their studies generated a number of fascinating conclusions. Literacy—no matter at what point in life the skill is acquired, in youth or as an adult—enhances brain response in three ways:

1. It boosts the organization of the visual cortex. Located toward the back of the brain, this is the area that processes visual information.
2. It allows the area of the brain responsible for spoken language—the planum temprale—to be activated by written sentences.
3. It refines how the brain processes spoken language.

Granted, there is much more detail to understand behind these conclusions, and I certainly invite you to read the entire article. Still, for us as educators, these conclusions hold useful insights.

In being aware of how literacy is related to these other skills, such as speaking and visual processing, we can use this information as yet another tool to help us better understand what we can expect from our students, no matter their ages. If they come into our classroom able to read, we know that we can expect them to have greater capacity for speech. If they come in with fewer or no reading skills, we might want to be aware that they might have challenges in processing visual input. 

Given these conclusions, the more we can continue to develop technology solutions that can teach while detecting deficiencies and adapt to student needs “on the fly,” the better we will be able to individualize instruction, fill in gaps in learning and strengthen essential skills.

As these scientists continue their investigations and the research sheds more light on how reading affects brain processing, we as educators will continue to increase our abilities to make better targeted instructional decisions that will help every individual student achieve optimal success.

Bilingual Babies: Language Delay or Learning Advantage?

• May 3, 2011 by Cory Armes

Over the years, many people have speculated about the advantages and disadvantages of exposing an infant to a second language.  On one hand, it sounds great to think that children could be proficient in two languages by the time they go to school but, on the other hand, there is the concern that adding a second language could cause confusion and even delay language development in very young children. 

Fortunately, Janet Werker, a psychologist at Vancouver's University of British Columbia, and her colleagues discovered that learning two languages simultaneously does not cause confusion and, in fact, can give young children cognitive advantages over their monolingual peers.  It now appears that bilingual children develop enhanced visual sensitivity to language as well as the auditory sensitivity that we would expect.

Most people in other countries speak multiple languages and researchers have not found real evidence of language confusion in children who learn more than one language at a time.  Of course, infants and toddlers who grow up in bilingual homes often will mix the two languages and that ‘mixing’ even has a name: code-switching.  By the time these babies are three years of age, they will move back and forth between the languages but they also naturally learn to follow rules that govern that movement. For example, if one parent is not bilingual, they stick to the dominant language for that parent but will code-switch with the bilingual parent. 

The study[i] also tested visual-language discrimination with four, six and eight month-olds and found that at the two earlier ages, infants can distinguish between two spoken languages when looking at a video of a person speaking with the sound muted, even if they are only familiar with one of the languages.  By eight months of age, the babies’ brains can even discriminate between two unfamiliar languages simply by watching someone speak. Further studies will determine how long this ability is maintained in childhood but it does appear that there is a lasting influence from early exposure to additional languages. 

Research also indicates that babies growing up in a bilingual environment are better able to attend to perceptual cues such as a change in voice tone or facial expression, in both languages and can apply this ability to distinguish things in the world as well.  Additional research [ii] suggests that bilingual children also could have more flexibility in learning.  

So, if you speak two languages fluently, share them with your babies from day one.  Expanding infancy with a second language could provide stronger cognitive skills, more perceptive social skills and better learning in general.  Don’t worry about videos, flash cards or other fancy options for teaching babies a second language - just talk and read together!
