Lost medieval manuscripts inferred by family tree

Agent-based simulations suggest that up to 60% of medieval texts and over 95% of manuscripts are at risk of extinction due to limited copies made early in their creation. The model reveals that cultural heritage is fragile and shaped by randomness, historical contingencies, and human choices.

Italians and Dutch share the same gestural instinct for teaching

Researchers found that Italian and Dutch adults increased use of two-handed representational gestures when teaching children, suggesting a shared communicative strategy for young learners. This finding supports theories of folk pedagogy and highlights the importance of multimodal scaffolding in human cultural transmission.

Nightingales strike the right chord

Researchers found that male nightingales precisely match pitch, but also adjust note length to achieve a trade-off strategy. They exhibit flexibility in how closely they match pitch versus duration depending on the combination heard. This ability requires rapid processing and neural flexibility.

ECNU Review of Education unveils the evolution of LLMs in intelligent Chinese composition tutoring

The ELion Intelligent Chinese Composition Tutoring System uses LLMs to evaluate student essays across four dimensions, providing detailed assessments and personalized feedback. The system has been instrumental in addressing teachers' excessive grading workloads and has facilitated the analysis of nearly 50,000 compositions.

ECNU Review of Education study explores how large language models can revolutionize teaching as personalized assistants

A study explores how large language models (LLMs) can transform teaching by generating customized educational materials, assessing student progress, and providing targeted feedback. LLMs excel at automating routine tasks, reducing teachers' workload and enabling them to focus on mentoring students.

To the brain, Esperanto and Klingon appear the same as English or Mandarin

A new study by MIT researchers finds that constructed languages such as Esperanto and Klingon elicit similar responses in the brain's language-processing network, suggesting that meaning is a key feature of language. This discovery helps define some of the key properties of language and narrows down the question of what a language is.

Northerners, Scots and Irish excel at detecting fake accents to guard against outsiders, Cambridge study suggests

A Cambridge study suggests that people from Northern Ireland, Scotland, and Ireland are better at detecting fake accents than those from London and the Southeast. The study found that participants were able to detect fake accents with an accuracy of around 60%, varying by region and cultural homogeneity.

How do new words arise in social media?

Researchers analyzed 650 million tweets to identify new words and tracked their adoption. Words used by central users persisted longer, while those with less central positions had a rapid rise and decline. The study reveals the predictive power of social network position in shaping language.

Languages are louder in the tropics

Researchers analyzed a large database of languages to verify the relationship between climate and language sound. They found that languages around the equator tend to have higher sonority indexes, but some exceptions exist, such as Mesoamerica and Mainland Southeast Asia.

A unified theory of the lexicon and the mind: Researchers find common cognitive foundation for child language development and language evolution

A study by University of Toronto researchers found that child language development and language evolution share a common cognitive foundation, based on a core knowledge base. The team built a computational model that predicts word meaning extension patterns across languages and time scales, highlighting the role of visual, associative,...

Chimpanzees combine calls to communicate new meaning

A study by the University of Zurich found that chimpanzees understand and respond strongly to combined calls, which they use to recruit group members in threatening situations. This discovery sheds light on the potential evolutionary origins of language's compositional structure, suggesting it may be at least 6 million years old.

Elephants as a new model for understanding human evolution

Researchers found that elephants exhibit hallmarks of domestication, including low aggression, empathic behaviour, and social learning. They propose that elephants' massive size and safe environment may have relaxed selective pressures for aggression, allowing for the evolution of prosocial behaviour.

The universal sound of swearing across languages

Research suggests a universal pattern in profanity across different languages, with the lack of approximants being a common feature when perceiving swear words. Participants rated pseudo-words with and without approximants differently, indicating that approximant-free words were more likely to be considered swear words.

Genes and languages not always together

A global analysis of matches and mismatches between human genetic and linguistic histories found that populations often shift to neighboring languages despite genetic differences. This suggests that giving up one's language isn't difficult, but preserving original linguistic identity is rare despite genetic assimilation.

A new approach to identify mammals good at learning sounds

A recent study found that most vocal learners, such as dolphins and whales, sound higher than expected based on their body size, not lower. This challenges the idea that faking body size is linked to vocal learning and suggests a different evolutionary scenario for vocal communication in mammals.

Tonal languages require humidity

Researchers found that tonal languages are more prevalent in humid climates, while simpler tone pitches dominate dry regions. The study suggests that humidity affects vocal fold elasticity and ion balance, making it easier to produce a wide range of tones.
