This article shows new evidence which suggests that language is learned in circuits that are used for many other purposes, instead of the common claim that language acquisition occurs in a specific part of the brain dedicated to the purpose. How good we are at remembering vocabulary relates to how good we are at declarative memory, which is used to remember shopping lists or people's faces. Grammar in children, on the other hand, correlates most strongly to procedural memory which is used for driving or playing an instrument.

This paper discusses how the gene FOXP2 is related to certain speech and language disorders, such as apraxia, or difficulty coordinating parts of the mouth to form speech. This research is important when placed into the wider debate of Nature Vs. Nurture, as it demonstrates that genetics may have the capacity to influence language acquisition.

This article talks about second language acquisition, and a higher efficacy rate in those who are fully immersed in the language they're learning. The study concluded that those in bilingual immersion programs or study-abroads exhibit higher levels of motivation to learn the language due to a desire to assimilate.

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.

This article focussed on how the covid lockdown had affected the language acquisition of children, ranging from about 1 to 3 years old. It talked about how screen use was shown to lower the amount of words learned during the same periods of time as compared to face to face interaction with another person.

Geared for laypeople, this article briefly explains what immersion schools are and reviews research pertaining to language immersion schools, as well as the benefits of teaching general academic content using the target second language.

An article that discusses how much dogs are able to understand human language, and why their understanding is limited.

Elise Piazza, lead author and a postdoctoral research associate with the Princeton Neuroscience Institute, said, "Motherese contains exaggerated pitch contours and repetitive rhythms that help babies segment the complex noises around them into building blocks of language." She added that the speaking style also helps parents capture the attention of their babies and engage them emotionally.

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.

Translanguaging: the act performed by bilinguals of accessing different linguistic features or modes of languages to maximize communicative potential. Dr. Ofelia Garcia, a scholar of multilingualism, argues that past models of bilingual education are insufficient for highly linguistically-diverse populations. Multilingual education should not only enable the acquisition of multiple languages, but also recognize the actual linguistic practices and language blending employed by teachers and students.

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.

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 longitudinal study, led by Mary E. Brushe, a researcher at the Telethon Kids Institute at the University of Western Australia, gathered data from 220 families across South Australia, Western Australia and Queensland with children who were born in 2017. Once every six months until they turned 3, the children wore T-shirts or vests that held small digital language processors that automatically tracked their exposure to certain types of electronic noise, as well as language spoken by the child, the parent or another adult. The researchers were particularly interested in three measures of language: words spoken by an adult, child vocalizations and turns in the conversation. They modeled each measure separately and adjusted the results for age, sex and other factors, such as the mother's education level and the number of children at home. Researchers found that at almost all ages, increased screen time squelched conversation. When the children were 18 months old, each additional minute of screen time was associated with 1.3 fewer child vocalizations, for example, and when they were 2 years old, an additional minute was associated with 0.4 fewer turns in conversation. The strongest negative associations emerged when the children were 3 years old - and were exposed to an average of 2 hours 52 minutes of screen time daily. At this age, just one additional minute of screen time was associated with 6.6 fewer adult words, 4.9 fewer child vocalizations and 1.1 fewer turns in conversation.

This article explains a study conducted to analyze how modern technology affects linguistic education. Based on data from 1990 to 2015, it concluded that technology interventions support language learning.

This study looks into how cultural learning can affect or improve second language acquisition, specifically looking into mandarin-speakers acquiring english.

"In recent decades, the study of language acquisition and instruction has increasingly focused on "chunking": how children learn language not so much on a word-by-word basis but in larger "lexical chunks" or meaningful strings of words that are committed to memory ... A native speaker picks up thousands of chunks like "heavy rain" or "make yourself at home" in childhood, and psycholinguistic research suggests that these phrases are stored and processed in the brain as individual units."

Good find, Ryan! I also took the video link and embedded it into our moodle page.

This review considers speaking in a second language from the perspective of motor-sensory control. Previous studies relating brain function to the prior acquisition of two or more languages (neurobilingualism) have investigated the differential demands made on linguistic representations and processes, and the role of domain-general cognitive control systems when speakers switch between languages.
