Research from Concordia University in Montreal reveals a new perk visible in the problem-solving skills of bilingual toddlers. The study assessed the vocabularies of 39 bilingual children and 43 monolinguals when they were aged 24 months, and then again at 31 months. During the second assessment, the researchers also had the young participants perform a battery of tasks to test their cognitive flexibility and memory skills. While overall, there was little difference between the bilingual and monolingual toddlers, bilingual children performed significantly better on the conflict inhibition tasks than did their monolingual counterparts. Conflict inhibition refers to the mental process of overriding a well-learned rule that you would normally pay attention to. These were the two tasks: 1. Reverse categorization -- participants were told to put a set of little blocks into a little bucket and big blocks into a big bucket. Then the instructions were switched -- big blocks in the little bucket and little blocks in the big bucket.
2. Shape conflict -- participants were shown pictures of different sized fruit and asked to name them. Then a new series of images was shown, with a small fruit embedded inside a large one. Toddlers were asked to point to the little fruit.
Crivello, one of the lead researchers, commented that "Language switching underlies the bilingual advantage on conflict tasks. In conflict inhibition, the child has to ignore certain information -- the size of a block relative to a bucket, or the fact that one fruit is inside another. That mirrors the experience of having to switch between languages, using a second language, even though the word from a first language might be more easily accessible."
Responsive interactions are the key to toddlers' ability to learn language, according to a new study. Researchers studied 36 two-year-olds, who learned new verbs either through training with a live person, live video chat technology such as Skype, or prerecorded video instruction. Children learned new words only when conversing with a person live and in the video chat, both of which involve responsive social interactions, thus highlighting the importance of responsive interactions for language learning.
(Jump to point 3). Children learn language through hearing, so making sure they have lots of things to listen to is critical. Toddlers whose mothers talked with them have bigger vocabularies.
The more parents talk to their children, the faster those children's vocabularies grow and the better their intelligence develops. The problem seems to be cumulative. By the time children are two, there is a six-month disparity in the language-processing skills and vocabulary of toddlers from low-income families. Toddlers learn new words from their context, so the faster a child understands the words he already knows, the easier it is for him to attend to those he does not.
Dr Anne Fernald, of Stanford, found that words spoken directly to a child, rather than those simply heard in the home, are what builds vocabulary. Plonking children in front of the television does not have the same effect. Neither does letting them sit at the feet of academic parents while the grown-ups converse about Plato.
The effects can be seen directly in the brain. Kimberly Noble of Columbia University studies how linguistic disparities are reflected in the structure of the parts of the brain involved in processing language. Although she cannot yet prove that hearing speech causes the brain to grow, it would fit with existing theories of how experience shapes the brain. Babies are born with about 100 billion neurons, and connections between these form at an exponentially rising rate in the first years of life. It is the pattern of these connections which determines how well the brain works, and what it learns. By the time a child is three, there will be about 1,000 trillion connections in his brain, and that child's experiences continuously determine which are strengthened and which pruned. This process, gradual and more-or-less irreversible, shapes the trajectory of the child's life.And it is this gap, more than a year's pre-schooling at the age of four, which seems to determine a child's chances for the rest of his life.
"They are making the inference - not consciously - that when someone has difficulty making a word they are most likely referring to an object that is rare," says Aslin.
This article essentially describes how research has shown that 18-24 months of age is the prime time to help their verbal communication skills in later years.
A new study, conducted by Dr. Catherine Birken, a pediatrician and scientist at the Hospital for Sick Children in Toronto, Ontario, revealed the following: the more time children between the ages of six months and two years spent using handheld screens such as smartphones, tablets and electronic games, the more likely they were to experience speech delays.
In the study, which involved nearly 900 children, parents reported the amount of time their children spent using screens in minutes per day at age 18 months. Researchers then used an infant toddler checklist, a validated screening tool, to assess the children's language development also at 18 months. They looked at a range of things, including whether the child uses sounds or words to get attention or help and puts words together, and how many words the child uses. Twenty percent of the children spent an average of 28 minutes a day using screens, the study found. Every 30-minute increase in daily screen time was linked to a 49% increased risk of what the researchers call expressive speech delay, which is using sounds and words.
Commenting on the study, Michelle MacRoy-Higgins and Carlyn Kolker, both speech pathologists/therapists and co-authors of "Time to Talk: What You Need to Know About Your Child's Speech and Language Development," offered this advice: interact with your child. The best way to teach them language is by interacting with them, talking with them, playing with them, using different vocabulary, pointing things out to them and telling them stories.
Children aged four and younger who speak two languages or are learning a second have more rapid improvements in inhibitory control, a study by the University of Oregon has said. Inhibitory control is the ability to stop a hasty reflexive response in behaviour or decision-making and use higher control to react in a more adaptive way.
"Inhibitory control and executive function are important skills for academic success and positive health outcomes and well-being later in life," said Atika Khurana, the study's co-author and a professor in the Department of Counselling Psychology and Human Services and scientist at the UO's Prevention Science Institute. "The development of inhibitory control occurs rapidly during the preschool years," she said. "Children with strong inhibitory control are better able to pay attention, follow instructions and take turns. "This study shows one way in which environmental influences can impact the development of inhibitory control during younger years."
Sound symbolism is a non-arbitrary relationship between speech sounds and meaning. We review evidence that, contrary to the traditional view in linguistics, sound symbolism is an important design feature of language, which affects online processing of language, and most importantly, language acquisition. We propose the sound symbolism bootstrapping hypothesis, claiming that (i) pre-verbal infants are sensitive to sound symbolism, due to a biologically endowed ability to map and integrate multi-modal input, (ii) sound symbolism helps infants gain referential insight for speech sounds, (iii) sound symbolism helps infants and toddlers associate speech sounds with their referents to establish a lexical representation and (iv) sound symbolism helps toddlers learn words by allowing them to focus on referents embedded in a complex scene, alleviating Quine's problem. We further explore the possibility that sound symbolism is deeply related to language evolution, drawing the parallel between historical development of language across generations and ontogenetic development within individuals. Finally, we suggest that sound symbolism bootstrapping is a part of a more general phenomenon of bootstrapping by means of iconic representations, drawing on similarities and close behavioural links between sound symbolism and speech-accompanying iconic gesture.
This source talks about different experiments done on toddlers who were bilingual and not. The underlying findings:
- Being bilingual doesn't confuse children, they are able to understand that the languages are separate.
- Being bilingual actually has longterm effects (especially with cognitive development).
This month, the journal Pediatrics published a study that used functional magnetic resonance imaging to study brain activity in 3-to 5-year-old children as they listened to age-appropriate stories. The researchers found differences in brain activation according to how much the children had been read to at home.
Children whose parents reported more reading at home and more books in the home showed significantly greater activation of brain areas in a region of the left hemisphere called the parietal-temporal-occipital association cortex. This brain area is "a watershed region, all about multisensory integration, integrating sound and then visual stimulation," said the lead author, Dr. John S. Hutton, a clinical research fellow at Cincinnati Children's Hospital Medical Center.
This region of the brain is known to be very active when older children read to themselves, but Dr. Hutton notes that it also lights up when younger children are hearing stories. What was especially novel was that children who were exposed to more books and home reading showed significantly more activity in the areas of the brain that process visual association, even though the child was in the scanner just listening to a story and could not see any pictures.
"When kids are hearing stories, they're imagining in their mind's eye when they hear the story," said Dr. Hutton. "For example, 'The frog jumped over the log.' I've seen a frog before, I've seen a log before, what does that look like?"
The different levels of brain activation, he said, suggest that children who have more practice in developing those visual images, as they look at picture books and listen to stories, may develop skills that will help them make images and stories out of words later on.
"It helps them understand what things look like, and may help them transition to books without pictures," he said. "It will help them later be better readers because they've developed that part of the brain
"...for many Swedes, gender equality is not enough. Many are pushing for the Nordic nation to be not simply gender-equal but gender-neutral. ... Just days after International Women's Day a new pronoun, hen (pronounced like the bird in English), was added to the online version of the country's National Encyclopedia. ... critics believe it can be psychologically and socially damaging, especially for children ... toddlers cannot weigh arguments for and against linguistic interventions and they do not conceive of or analyze gender roles in the way that adults do ... One Swedish school got rid of its toy cars because boys 'gender-coded' them and ascribed the cars higher status than other toys."
"...scientists found that different toddler sounds - or "vocalizations" - emerge and fade in a definite rhythm in the course of a tantrum. "We have the most quantitative theory of tantrums that has ever been developed in the history of humankind" ... where one age-old theory of tantrums might suggest that meltdowns begin in anger (yells and screams) and end in sadness (cries and whimpers), Potegal found that the two emotions were more deeply intertwined. ... The trick in getting a tantrum to end as soon as possible, Potegal said, was to get the child past the peaks of anger. Once the child was past being angry, what was left was sadness, and sad children reach out for comfort. The quickest way past the anger, the scientists said, was to do nothing."
Researchers have found they can go far in predicting which children with autism will eventually develop language and which will not - based on differences in brain activity when the children are infants and toddlers. The findings represent a potential breakthrough in tailoring future early intervention programs to improve communication and language even before a diagnosis of autism is possible at 18 to 24 months.
