A team of researchers from Rice University and University of Maryland, College Park argue that it is more productive from a developmental perspective to describe spoken language as a special type of music. A review of existing studies presents a compelling case that musical hearing and ability is essential to language acquisition. In addition, we challenge the prevailing view that music cognition matures more slowly than language and is more difficult; instead, the researchers argue that music learning matches the speed and effort of language acquisition, and indeed, that "it is our innate musical intelligence that makes us capable of mastering speech." They conclude that music merits a central place in our understanding of human development.

The researchers of this study advance the idea that spoken language is introduced to the child as a vocal performance, and children attend to its musical features first. Without the ability to hear musically, it would be impossible to learn to speak. In addition, they question the view that music is acquired more slowly than language (Wilson, 2012) and demonstrate that language and music are deeply entangled in early life and develop along parallel tracks. Rather than describing music as a "universal language," they find it more productive from a developmental perspective to describe language as a special type of music in which referential discourse is bootstrapped onto a musical framework. Newborn infants' extensive abilities in different aspects of speech perception have often been cited as evidence that language is innate (e.g., Vouloumanos and Werker, 2007). However, these abilities are dependent on their discrimination of the sounds of language, the most musical aspects of speech. Music has a privileged status that enables us to acquire not only the musical conventions of our native culture, but also enables us to learn our native language. Without the ability to hear musically, we would be unable to learn language.

The key takeaways: 1. Ensuring rich, socially-contextualized language exposure in both languages. Pediatricians advise non-English-speaking parents to read aloud and sing and tell stories and speak with their children in their native languages, so the children get that rich and complex language exposure, along with sophisticated content and information, rather than the more limited exposure you get from someone speaking a language in which the speaker is not entirely comfortable. 2. Exposure has to be person-to-person; screen time doesn't count for learning language in young children - even one language - though kids can learn content and vocabulary from educational screen time later on. 3. It does take longer to acquire two languages than one, says Dr. Erika Hoff, a developmental psychologist who specializes in early language development. "A child who is learning two languages will have a smaller vocabulary in each than a child who is only learning one; there are only so many hours in the day, and you're either hearing English or Spanish," Dr. Hoff said. The children will be fine, though, she said. They may mix the languages, but that doesn't indicate confusion. "Adult bilinguals mix their languages all the time; it's a sign of language ability," she said. 4. If exposed to the target languages at a younger age, children generally will sound more nativelike. On the other hand, older children may learn more easily. Gigliana Melzi, a developmental psychologist and associate professor of applied psychology, states, "The younger you are, the more head start you have," she said. "The older you are, the more efficient learner you are, you have a first language you can use as a bootstrap."

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.

Word "edges" are important for language acquisition. Children start to learn the sound of words by remembering the first and last syllables. A new study sheds light on the information the infant brain uses during language acquisition and the format in which it stores words in its memory. Infants start to learn words very early, during the first months of life, and to do so they have to memorise their sounds and associate them with meanings. The study by Silvia Benavides-Varela (now at the IRCCS Fondazione Ospedale San Camillo in Venice, but at SISSA at the time the study was performed) and Jacques Mehler, neuroscientist at SISSA, revealed the format in which infants remember their first words. In particular, the two scientists saw that infants aged about seven months accurately encode the sound and position of the first and last syllable, whereas they have difficulty retaining the order of syllables in the middle.

Without understanding the 'referential function' of language (words as 'verbal labels', symbolizing other things) it is impossible to learn a language. Is this implicit knowledge already present early in infants? Marno, Nespor, and Mehler of the International School of Advanced Studies conducted experiments with infants (4 months old). Babies watched a series of videos where a person might (or might not) utter an (invented) name of an object, while directing (or not directing) their gaze towards the position on the screen where a picture of the object would appear. By monitoring the infants' gaze, Marno and colleagues observed that, in response to speech cues, the infant's gaze would look faster for the visual object, indicating that she is ready to find a potential referent of the speech. However, this effect did not occur if the person in the video remained silent or if the sound was a non-speech sound. "The mere fact of hearing verbal stimuli placed the infants in a condition to expect the appearance, somewhere, of an object to be associated with the word, whereas this didn't happen when there was no speech, even when the person in the video directed the infant's gaze to where the object would appear, concludes Marno. "This suggests that infants at this early age already have some knowledge that language implies a relation between words and the surrounding physical world. Moreover, they are also ready to find out these relations, even if they don't know anything about the meanings of the words yet. Thus, a good advice to mothers is to speak to their infants, because infants might understand much more than they would show, and in this way their attention can be efficiently guided by their caregivers."

An infant's mother tongue creates neural patterns that the unconscious brain retains years later, even if the child totally stops using the language, (as can happen in cases of international adoption) according to a new joint study by scientists at the Montreal Neurological Institute and Hospital. The study offers the first neural evidence that traces of the "lost" language remain in the brain and suggests that early-acquired information is not only maintained in the brain, but unconsciously influences brain processing for years, perhaps for life -- potentially indicating a special status for information acquired during optimal periods of development. This could counter arguments not only within the field of language acquisition, but across domains, that neural representations are overwritten or lost from the brain over time.

This seminal longitudinal study, conducted by Goodwyn, Acredolo and Brown (2000), evaluated the benefits of purposefully encouraging hearing infants to use simple gestures as symbols for objects, requests, and conditions. Researchers measured the receptive and expressive language abilities of 103 babies via standardized language tests at the age of 11, 15, 19, 24, 30, and 36 months. Their findings suggest that symbolic gesturing does not hamper children's early verbal development, and may even facilitate it. The possible reasons underlying the results: increases in infant-directed speech, infant-selected topic selection, and scaffolding that encourages communication.

This article talks about how sleep plays an active role in language and brain development and the role it plays in early language acquisition.

A new study conducted by the University of Pennsylvania has shown that children as young as two understand basic grammar rules when they first learn to speak and are not simply imitating adults. The study also applied the same statistical analysis on data from one of the most famous animal language-acquisition experiments -- Project Nim -- and showed that Nim Chimpsky, a chimpanzee who was taught sign language over the course of many years, never grasped rules like those in a two-year-old's grammar. "When you compare what children should say if they follow grammar against what children do say, you find it to almost indistinguishable," Professor of Linguistics Charles Yang said. "If you simulate the expected diversity when a child is only repeating what adults say, it produces a diversity much lower than what children actually say." As a comparison, Yang applied the same predictive models to the set of Nim Chimpsky's signed phrases, the only data set of spontaneous animal language usage publicly available. He found further evidence for what many scientists, including Nim's own trainers, have contended about Nim: that the sequences of signs Nim put together did not follow from rules like those in human language. Nim's signs show significantly lower diversity than what is expected under a systematic grammar and were similar to the level expected with memorization. This suggests that true language learning is -- so far -- a uniquely human trait, and that it is present very early in development.

In this TED-Talk, Dr. Naja Ferjan Ramirez, linguistics professor at the University of Washington and a specialist in the brain processes of children 0-3 years, lays out the benefits of bilingualism, tells how to optimize language learning to achieve better acquisition, and dispels some common concerns about the cons of creating a bilingual child. No surprises here: start early, and create conditions where babies are exposed to the desired target languages-this will enable babies to process the sounds of dual languages, not just one. Ideally, babies will have frequent, social interactions with fully-competent, fluent speakers of the target languages. Ramirez also mentions a major cognitive benefit to bilingualism: a strengthened prefrontal cortex: the area of the brain that deals with task-switching and flexible thinking.

New research suggests it's how parents talk to their infants, not just how often, that makes a difference for language development. Infants whose mothers had shown "sensitive" responses--verbally replied to or imitated the babies' sounds--showed increased rates of consonant-vowel vocalizations, meaning that their babbling more closely resembled something like real syllables, paving the way for real words. The same babies were also more likely to direct their noises at their mothers, indicating that they were "speaking" to them rather than simply babbling for babbling's sake. "The infants were using vocalizations in a communicative way, in a sense, because they learned they are communicative," study author Julie Gros-Louis, a psychology professor at the University of Iowa, said in a statement. In other words, by acting like they understood what their babies were saying and responding accordingly, the mothers were helping to introduce the concept that voices, more than just instruments for making fun noises, could also be tools for social interaction.

This study looks at how age of acquisition affects second language learning and how it can influence cognitive processing. Bilingual Spanish and English speakers appear to have an advantage over monolingual individuals, with bilingualism shaping word learning and memory capacity. Specifically, early bilinguals performed better than monolingual individuals and late bilingual learners. There were two mechanisms discussed at the end of the study. The first is based on the critical-period-based phenomenon. The second is based on longer exposure to the two languages, which contributes to bilingual advantages.

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.

The LENA System measures the early language environment of children birth to 48 months. It consists of a compact digital recorder with clothing so a child can wear it comfortably; software that turns the recording into data; and a cloud-based system for managing the data. Feedback from LENA helps parents and caregivers increase the quantity and quality of interactive talk. While words are important, "conversational turns" are even more so - times when an adult says something and the child responds, or vice versa. Turns measure interactions, and according to research, they're a very powerful predictor of brain growth. LENA devices were mentioned in "In the Beginning Was the Word" article from _The Economist_.

Hawaii put forward a plan Tuesday, 1/17/2023, to make preschool available to all 3- and 4-year-olds by 2032, which if successful would put the state in a rarified group of states managing to provide pre-kindergarten education to most of its children. Hawaii's leaders have aspired to universal pre-K for decades but have found it elusive. A recent analysis found the state was moving so slowly toward that goal that it would take 47 years to build all the public preschool capacity Hawaii needed. The state expects it will need 465 new classrooms to serve the additional students. Lt. Gov. Sylvia Luke, who has been tasked by Gov. Josh Green to lead the state's efforts, said only half of Hawaii's 35,000 3- and 4-year-olds attend preschool, either by paying expensive tuition for private schools or obtaining one of the few spots in publicly-funded pre-K programs. The state estimates there are about 9,200 children whose parents want to send them to preschool but aren't able. It's targeting its plans at this group.
