In this study we asked whether nonwords created by transposing two phonemes (/biks[open-mid back rounded vowel]t/) are perceived as being more similar to their base words (/bisk[open-mid back rounded vowel]t/) than nonwords created by substituting two phonemes (/bipf[open-mid back rounded vowel]t/). Using the short-term phonological priming and a…

Purpose: Persons with unilateral brain damage in the right hemisphere (RH) or left hemisphere (LH) show limitations in processing linguistic prosody, with yet inconclusive results on their ability to process prosodically marked structural boundaries for syntactic ambiguity resolution. We aimed at systematically investigating production and…

There is a long-standing debate in the literature about the benefits that acoustic components of Infant Directed Speech (IDS) might have for infants' language acquisition. One of the highly contested features is vowel space expansion, which refers to the enlargement of the acoustic space between the corner vowels /i, u, a/ in IDS compared to Adult…

This study examined how toddler looking to a discourse referent is mediated by the information status of the referent and the pitch contour of the referring expression. Eighteen-month-olds saw a short discourse of three sets of images with the proportion of looking time to a target analyzed during the final image. At test, the information status…

We examined what causes L1-L2 differences in sensitivity to prominence cues in discourse processing. Participants listened to recorded stories in segment-by-segment fashion at their own pace. Each story established a pair of contrasting items, and one item from the pair was rementioned and manipulated to carry either a contrastive or…

Purpose: Lexical stress and phoneme processes converge during phonological encoding, but the nature of the convergence has been debated. Stress patterns and phonemes may be integrated automatically and rigidly, resulting in a unified representation. Alternatively, stress and phoneme may be processed interactively based on sublexical contexts. The…

Most orthographies contain both accented and non-accented vowels. But are they processed as variants of the same letter unit or as separate abstract units? Recent research in French has revealed that accented vowels seem to be processed as separate units. Here we examined whether this phenomenon is universal or language-specific. We chose Spanish…

One feature of Spanish that presents some difficulties to second language (L2) learners whose first language (L1) is English concerns lexical stress. This study explores one aspect of the obstacle these learners face, weak phonological processing routines concerning stress inherited from their native language. Participants were L1 English L2…

Although it is clear that unaccented referring expressions are associated with given information in a discourse, it is less clear what aspects of givenness are relevant. We examine whether listeners' expectation of givenness depends on repetition of a referring expression or on contextual evocation of a referent. The results from two visual world…

Learning to use word versus phrase level prosody to identify compounds from lists is thought to be a protracted process, only acquired by 11 years (Vogel & Raimy, 2002). However, a recent study has shown that 5-year-olds can use prosodic cues other than stress for these two structures in production, at least for early-acquired noun-noun…

Children with autism often show atypical brain lateralization for speech and language processing, however, it is unclear what linguistic component contributes to this phenomenon. Here we measured event-related potential (ERP) responses in 21 school-age autistic children and 25 age-matched neurotypical (NT) peers during listening to word-level…

Previous research on infant-directed speech (IDS) and its role in infants' language development has largely focused on mothers, with fathers being investigated scarcely. Here we examine the acoustics of IDS as compared to adult-directed speech (ADS) in Norwegian mothers and fathers to 8-month-old infants, and whether these relate to direct…

A phoneme-detection task shows that listeners of Sepedi use semantic information in processing but not prosody (Experiment 1). Sepedi is a language with no grammaticalised prosodic expression of focus. Sepedi listeners detected phoneme targets faster when the phoneme-bearing words were focussed (as opposed to unfocussed) but not when occurring in…

This study investigates for the first time the comprehension of rhetorical questions (RhQs) in bilingual children. RhQs are non-canonical questions, as they are not used to request information, but to express the speaker's belief that the answer is already obvious. This special pragmatic meaning often arises by means of specific prosodic and…

Bilingual infants must navigate the similarities and differences between their languages to achieve native proficiency in childhood. Bilinguals learning to find individual words in fluent speech face the possibility of conflicting cues to word boundaries across their languages. Despite this challenge, bilingual infants typically begin to segment…
