Sentinels are a conspicuous feature of some cooperative societies and are often assumed to provide benefits in terms of increased predator detection. Similar to other cooperative behaviours, variation in investment in sentinel behaviour should reflect variation in the benefits of such behaviour. However, evidence for this is inconclusive: to date experiments have manipulated the cost of sentine...

This paper explores phonetic and phonological features of the stress system in Émérillon, a Tupi-Guaraní language spoken by approximately 400 people in French Guiana. Stress placement in both elicited wordlist and natural discourse data is examined. Three potential acoustic correlates of stress (fundamental frequency, duration, and intensity) are examined in order to provide quantitative verifi...

As any language, Sign Language (SL) has a vocabulary and a grammar [1][2]. In addition, the SL has the specificity to be practiced in the space. The work presented in this article offers a pragmatic approach to a classification system for signs of French Sign Language (FSL) to facilitate the access to the vocabulary of this language with the least amount of search items. The objective is to set...

In this paper, we show that adult listeners who speak the same native language but live in different linguistic environments differ in their use of prosodic cues that signal word boundaries in the native language. Non-utterance-final word-final syllables have higher fundamental frequency in French. Adult native French listeners living in France or in the US completed an artificial-language segm...

In a language identification task, native Belgian French and native Swiss French speakers identified French from France as their own variety. However, Canadian French was not subject to this bias. Canadian and French listeners didn't claim a different variety as their own.

Objectives: The current study mainly aimed at studying the effect of Knowledge of Result (KR) feedback timing and result-estimation opportunity before receiving delayed KR on learning a new speech motor skill in monolingual healthy adults.  Methods: Thirty-nine Persian healthy adults were randomly divided into three groups. Each group received immediate KR, delayed KR (after eight seconds), or...
