The cross-cultural big two: A culturally decentered theoretical and measurement model for personality traits.

A "big two" model has shown stronger cross-cultural replicability and links to theory than other contemporary models of personality trait structure. However, its theoretical and measurement models require better specification. We address this to create an initial English-language version of the Cross-Cultural Big Two Inventory with an empirically informed and culturally decentered approach, meaning that input from global contexts is used from the outset, without prioritizing Western perspectives.

Grambank reveals the importance of genealogical constraints on linguistic diversity and highlights the impact of language loss.

While global patterns of human genetic diversity are increasingly well characterized, the diversity of human languages remains less systematically described. Here, we outline the Grambank database. With over 400,000 data points and 2400 languages, Grambank is the largest comparative grammatical database available.

The extent and degree of utterance-final word lengthening in spontaneous speech from 10 languages.

Words in utterance-final positions are often pronounced more slowly than utterance-medial words, as previous studies on individual languages have shown. This paper provides a systematic cross-linguistic comparison of relative durations of final and penultimate words in utterances in terms of the degree to which such words are lengthened. The study uses time-aligned corpora from 10 genealogically, areally, and culturally diverse languages, including eight small, under-resourced, and mostly endangered languages, as well as English and Dutch.

Nouns slow down speech across structurally and culturally diverse languages.

By force of nature, every bit of spoken language is produced at a particular speed. However, this speed is not constant-speakers regularly speed up and slow down. Variation in speech rate is influenced by a complex combination of factors, including the frequency and predictability of words, their information status, and their position within an utterance.

The neurophysiology of language processing shapes the evolution of grammar: evidence from case marking.

Do principles of language processing in the brain affect the way grammar evolves over time or is language change just a matter of socio-historical contingency? While the balance of evidence has been ambiguous and controversial, we identify here a neurophysiological constraint on the processing of language that has a systematic effect on the evolution of how noun phrases are marked by case (i.e. by such contrasts as between the English base form she and the object form her).
