This article looks at Finnish language and talks about how verbal repetition of new words helps with vocabulary development, and can cause the brain to have neural response enhancements. This response also indicated how well they were able to retain the vocabulary. The language background of this study's participants was observed, and they found that those who had learned more languages earlier had greater brain flexibility to acquire new phonology.
This article describes a recent study in which scientists were able to use CT scans to generate 3-D models of Neanderthal ear structures. In the past, attempts to determine whether Neanderthals used language hinged on the hyoid bone, a single piece of the Neanderthal vocal tract. However, these scientists took a different approach by looking at the ears of Neanderthals to give clues about Neanderthal language. By running the ear models through computer programs, scientists were able to determine that the Neanderthal ear's "sweet spot" included higher frequencies characteristic of consonant production, and therefore human language. This is exciting because it gives scientists another piece in the puzzle of early human language development.
In 2017, Jonathan Harrington, University of Munich linguist, studied a group of British scientists isolated for four months in Antarctica, and found that their pronunciation of key words began becoming more phonologically similar. These findings lend credence to a phenomenon observed by linguists regarding how new languages evolve. Isolation leads to subtle accent changes, followed by the development of dialects, and eventually over a broad timespan, whole new tongues.
Outlines the importance of early children's language development. It highlights the importance of the four main components to early language development: Phonology, Semantics, Grammar and Pragmatics. This article shows the critical period of first 5 years in development as this is the time that baby's nerve connections are being made and those for speech/communication need to be built early on so that they're inherent to learning.
Dr. Mitsuhiko Ota, a linguist in the University of Edinburgh Language Sciences department, was the lead researcher in a 2018 study (Ota, Davies-Jenkins, and Skarabela 2018) examining infant-directed speech, a.k.a. baby talk. Across languages, lexical items specific to infant-directed speech (i.e., 'baby-talk words') are characterized by three major features:
1. onomatopoeia incorporated into non-arbitrary, "highly iconic" words, e.g. "quack", "bow wow"
2. diminutives, e.g. "daddy", "tummy"
3. reduplication, e.g. "din din", "easy peasy"
These three lexical characteristics may help infants discover the referential nature of words, identify word referents, and segment fluent speech into words. If so, the amount of lexical input containing these properties should predict infants' rate of vocabulary growth. To test this prediction, Ota's team tracked the vocabulary size in 47 English-learning infants from 9 to 21 months and examined whether vocabulary growth was related to measures of iconicity, diminutives, and reduplication in the lexical input at 9 months. The team's analyses showed that both diminutives and reduplication in the input were associated with vocabulary growth, although measures of iconicity were not. These results are consistent with the hypothesis that phonological properties typical of lexical input in infant-directed speech play a role in early vocabulary growth.
This article delves into the grammatical structure of sign languages and highlights the differences between spoken and signed languages. It places an emphasis on the primary differences between them, which is the fact that signed symbols can be delivered simultaneously instead of in a linear fashion.
