The Oto Monitor
There is a new product called Oto – “the First Monitor for Your Baby’s Healthy Brain Development”. (Learn about it at https://www.oyalabs.com/)
They’re electronic monitors you place around your home. The website says they use AI and Natural Language Processing to tally how many words a child hears, how many engaged, back-and-forth exchanges you have with your child, and the quality of your language including the ratio of positive to negative words.
If this were an academic study that I’d been asked to participate in with my child, I would absolutely say yes, because it would be fascinating to participate and see the research results!
But I’m a little troubled by the marketing of the device. It says “These indicators are proven to be critical for their IQ and emotional development.” The implication is that this device is essential for helping you ensure your child reaches their full potential. They also say “The number of words you speak to your child daily is a core metric – the more language, the better child’s outcomes.”
I worry that the parents who purchase this device would then become anxious, feel guilty when they weren’t talking, and become overly focused on talking and talking and talking to their child. This onslaught of words would be exhausting for me to produce as a parent and exhausting for a child to hear and may totally miss the point of how children most effectively learn language.
Bronson and Merryman (source) say “For years, the advice has been that the way to kick-start a child’s language learning was to simply expose kids to massive amounts of language. However, as we explain in our book NurtureShock, the newest science has concluded that the central role of the parent is not to push massive amounts of language into the child’s ears. Rather, the central role of the parent is to notice what’s coming from the child and respond accordingly.”
Let’s look more at what we know about language learning.
Can there be too little language in a child’s world?
There are definitely “linguistically poor” households, and this can absolutely lead to significant “vocabulary gaps.” In general, children from households with lower income and lower family education know fewer words. (source of chart above) Some examples from research:
- A child in a low income home will hear an average of 616 words in an hour, a child in an average professional home will hear 2153. (source)
- In one year, children from poor families hear 250,000 utterances at home, while children from wealthy families hear 4,000,000. (source)
- By age four, middle and upper class children hear 15 million more words than in working-class families, and 30 million more than in families on welfare. (source)
- By second grade, a middle income child will know ~6020 words. A low income child will know ~4168. (source)
- By 18 months, toddlers from disadvantaged families are already several months behind more advantaged children in language proficiency. (source)
- 5-year-old children of lower SES score two years behind on language tests. (source)
- When 18 month olds were shown two objects, then one was named aloud, higher SES toddlers could identify the right object in 750 milliseconds, lower SES toddlers were 200 milliseconds slower to respond. That slower mental processing speed means they have a harder time keeping up with teacher’s words. (source)
Not only are there fewer words spoken in a lower income household, the discussions that do happen are likely to be focused on daily life, such as what to eat, work schedule, and other practical topics. They are less likely to have wide-ranging discussions around the dinner table on a variety of topics. The parents may also work multiple jobs, which means less opportunity for reading bedtime stories. This may lead to the same words being used a lot, and fewer novel words that broaden the child’s vocabulary.
Also, in single parent households or homes where one partner is away at work, it may be more likely that the television is on in the background much of the time, which leads to less engagement and conversation between parent and child. (Source)
A child who understands fewer words and has slower processing speed when they begin school will not just start behind – they’ll stay behind. As the teacher talks and some kids understand all the words and all the concepts, and some kids can’t even understand the words used, they get lost before reaching the concepts. (source for graph below)
So yes, if there are too few words being used in a child’s environment, that child can be word poor. And yes, that will create academic challenges. But, that doesn’t necessarily mean the answer is to just talk a lot more…
What Is Responsive Language?
Imagine two scenes.
- A toddler is sitting and poking at her cheerios and poking at her spoon so it rattles on the table. The parent, wanting to be sure the child is receiving mental stimulation, talks about their day: “As soon as you’re done with your breakfast, we’re going to put your new red shoes on and we’re going to go for a walk, and maybe we’ll see some butterflies again. Remember, the last time we went to the bakery to buy bread and we saw two blue butterflies?” The child keeps poking at her food as the parent talks. “I’m going to get a book now – we can read it together.”
- As the toddler pokes, she looks up at the parent for their reaction. The parent sits with the child and says “you’re poking your cheerios with your finger. You pushed them all into a big pile on that side of your dish.” As the parent speaks, they point at the big pile. The child pushes a few more cheerios into the pile. “Now there are five more cheerios in the pile.” Then the child pats the spoon. “You’re using your hand to pat the spoon. The spoon makes a fun noise, doesn’t it?” The parent pats the spoon and says “It’s going rattle, rattle.” The toddler rattles the spoon some more, parent says “rattle, rattle” again. Then the child holds up the spoon to show it to the parent. “You picked up the spoon – can you use it to pick up some cheerios?”
In the first example, the parent’s voice is mostly background noise for the child whose attention is focused on the cereal and the spoon. There is also the chance of “criss-cross labeling” where if every time the child touches the spoon, the parent happens to talk about butterflies, the child could get confused about whether the thing they’re touching is called butterfly.
In the second example, the parent closely observed the child’s actions and where the child’s attention was focused, then talked about that. This gives the child the words for what they are experiencing in the moment with all their senses. This builds a much stronger connection between the words and their meaning. When you talk about a spoon later, the child can remember this moment and remember what the spoon felt like in their hand and the noise it made on the table.
To some parents, it may seem like talking about cheerios and a spoon is boring. They may feel like they need to jazz up the child’s learning with talking about bigger ideas. But slowing down to your toddler’s pace and tuning in to what they are in the process of exploring offers a meaningful connection for their learning.
There are three characteristics of responsive language: it’s prompt (happens within seconds of the child’s behavior, it’s contingent (related to the behavior) and it’s appropriate (parent responds in a positive and meaningful way). (source)
So, if a child showed a parent a ball, the parent would quickly respond, “Oh, you have a ball in your hand!” If the child said “ba”, the parent would say “Ball. Yes, it’s a green ball.”
Does responsive language increase learning?
- One study showed that when parents were more responsive, their children would reach all these milestones sooner: imitating parent’s words, first words, speaking 50 words, combining words to make a “sentence” and talking about the past.
- A parenting style that includes parental warmth, high expectations and clear routines is associated not just with language ability but also better memory and higher achievement. When parents use a lot of negative strategies, their children have more limited language skills. (Source)
- Children who hear more child-directed speech – not just overheard speech – process language faster and learn words more quickly. (source)
Here is a summary of other research:
In the second year, when infants begin to understand and produce words and simple phrases, responsiveness predicts the sizes of infants’ vocabularies… the diversity of infants’ communications… and the timing of language milestones… Infants of high-responsive mothers (90th percentile) … achieved language milestones such as first words, vocabulary spurt, and combinatorial speech, 4 to 6 months earlier than infants of low-responsive mothers… Toddlers of low-responsive fathers were 5 times more likely to display cognitive delays than were toddlers of high-responsive fathers… fathers’ responsiveness to their 2- and 3-year-olds predicted toddlers’ cognitive and language abilities within and across time… (source – includes citations for all studies)
How can you use responsive language?
Dr. Dana Suskind, author of Thirty Million Words recommends three steps for parents and caregivers to expand a child’s vocabulary:
- Tune In by paying attention to what your child is focused on
- Talk More with your child using lots of descriptive words
- Take Turns with your child by engaging in his or her conversation. (source)
- The Hanen Centre says that step 1 is OWL: “Observe Wait Listen. The parent needs to give the child the opportunity to take that first turn, so that the parent has something to respond to.” (Learn more about OWL – Observe, Wait, Listen.)
- Their next step is follow the child’s lead: imitate what the child says, interpret (what the child would say if they had the words), comment (giving the child words to describe what they are doing) or join in child-directed play. (Learn more.)
- Use parentese – that sing song higher voice parents use to talk to babies.
- Use motion – point to things as you talk about them, touch them, shake them. All this helps the child focus their attention while you label the objects.
- Talk about what they want to talk about (what they are doing or are paying attention to in the moment). Don’t change topics quickly.
- Don’t interrupt their attempts to communicate with you. Wait for them to get their thought out. Look at their face to show you are listening.
- Children also benefit from hearing lots of different people speak – at different pitches, tempos, and with different accents and facial expressions. So take them out in the world, so they have an opportunity to interact with diverse people.
- Reading to your child is also a huge influence on language learning. Learn about how to read to a child and lots of other literacy topics.
Don’t feel like you have to talk all the time
For brain development in general, children need three things: novelty (new experiences), repetition (the chance to explore something over and over to learn about it in depth from all angles), and down time (restful periods without lots of input when they can process all that they’ve seen and heard). This is true of language too.
Children need new words, they need to hear the same ones over and over in different contexts, and they also need quiet time for their inner thoughts to unfold. It is fine to have long periods of silence at home too. Even if you choose to have an Oto monitor listening in.
