Language is a universal human ability, acquired readily by young children, who otherwise struggle with many basics of survival. And yet, language ability variable across individuals. Naturalistic and experimental observations suggest that children’s linguistic skills vary factors like socioeconomic status gender. But which really influence day-to-day use? Here, we leverage speech technology in big-data approach to report on unique cross-cultural diverse data set: >2,500 d-long,...
Abstract This longitudinal study assessed three acoustic components of maternal infant-directed speech (IDS) – pitch, affect, and vowel hyperarticulation in relation to infants’ age their expressive vocabulary size. These individual were measured IDS addressed infants at 7, 9, 11, 15, 19 months ( N = 18). All exaggerated all ages mothers’ compared adult-directed speech. Importantly, the only significant predictor size 15 was hyperarticulation, but 9 beyond, not 7 months, pitch or affect any...
This study assessed cortical tracking of temporal information in incoming natural speech seven-month-old infants. Cortical refers to the process by which neural activity follows dynamic patterns input. In adults, it has been shown involve attentional mechanisms and facilitate effective encoding. However, infants, or its effects on processing have not investigated. measured infants and, given involvement this process, both infant-directed (IDS), is highly attractive less captivating...
The temporal modulation structure of adult-directed speech (ADS) is thought to be encoded by neuronal oscillations in the auditory cortex that fluctuate at different rates. Oscillatory activity phase-align amplitude modulations corresponding rates, thereby supporting parsing signal into linguistically relevant units. infant-directed (IDS) unexplored. Here we compare (AM) IDS recorded from mothers speaking, over three occasions, their 7-, 9-, and 11-month-old infants, same speaking ADS....
Dyslexia is a neurodevelopmental disorder manifested in deficits reading and spelling skills that consistently associated with difficulties phonological processing. genetically transmitted, but its manifestation particular individual thought to depend on the interaction of epigenetic environmental factors. We adopt novel interactional perspective early linguistic environment dyslexia by simultaneously studying two pre-existing factors, one maternal infant, may contribute these interactions;...
Mutual Exclusivity (ME) is a prominent constraint in language acquisition, which guides children to establish one-to-one mappings between words and referents. But how does unfolding experience of multiple-to-one word-meaning bilingual children's environment affect their understanding when use ME accept lexical overlap? Three-to-five-year-old monolingual simultaneous completed two pragmatically distinct tasks, where successful word learning relied on either the default or ability overlapping...
When addressing their young infants, parents systematically modify speech. Such infant-directed speech (IDS) contains exaggerated vowel formants, which have been proposed to foster language development via articulation of more distinct sounds. Here, this assumption is rigorously tested using both acoustic and , for the first time, fine-grained articulatory measures. Mothers were recorded speaking infant another adult, measures taken space, tongue lip movements length vocal tract. Results...
An auditory-visual speech benefit, the benefit that visual cues bring to auditory perception, is experienced from early on in infancy and continues be an increasing degree with age. While there both behavioural neurophysiological evidence for children adults, only exists infants - as no study has provided a comprehensive examination of infants. It also surprising most studies do not concurrently report looking behaviour especially since rests assumption listeners attend speaker's talking...
High levels of maternal responsiveness are associated with healthy cognitive and emotional development in infants. However, depression anxiety can negatively impact individual mothers’ infants’ expressive language abilities. Australian mother-infant dyads (N = 48) participated a longitudinal study examining the effect (when infants were 9- 12-months), symptoms on infant vocabulary size at 18-months. Global ratings stronger predictors than symptoms. moderated size. These results highlight...
Slow cortical oscillations play a crucial role in processing the speech amplitude envelope, which is perceived atypically by children with developmental dyslexia. Here we use electroencephalography (EEG) recorded during natural listening to identify neural patterns involving slow that may characterize In story paradigm, find atypical power dynamics and phase-amplitude coupling between delta theta dyslexic versus other child control groups (typically-developing controls, language disorder...
ABSTRACT The classical view is that perceptual attunement to the native language, which emerges by 6–10 months, developmentally precedes phonological feature abstraction abilities. That assumption challenged findings from adults adopted into a new language environment at 3–5 months imply they had already formed abstractions about their birth prior 6 months. As not been directly tested in infants, we examined 4–6‐month‐olds’ amodal of labial versus coronal place articulation distinction...

Long- and short-term musical training has been proposed to improve the efficiency of cortical tracking speech, which refers synchronization brain oscillations acoustic temporal structure external stimuli. Here, we study how sequences with different rhythm structures can guide dynamics auditory synchronized speech envelope. For this purpose, investigated effects prior exposure rhythmically structured on in Basque-Spanish bilingual adults (Experiment 1; N = 33, 22 female, Mean age 25 years)....
Summary Speakers accommodate their speech to meet the needs of listeners, producing different registers. One such register is L2 Accommodation (L2A), which way native speakers address non-native typically characterized by features as slow rate and phonetic exaggeration. Here, we investigated how impacts cortical encoding at levels language integration. Specifically, tested hypothesis that enhanced comprehension L2A compared with Native Directed Speech (NDS) involves more than just a slower...
Abstract Infant directed speech (IDS), the register adults use when talking to infants, has been shown have positive effects on attracting infants’ attention, language learning, and emotional communication. Here event related potentials (ERPs) are used investigate neural coding of IDS ADS (adult speech) as well their discrimination by both infants adults. Two instances vowel /i/, one extracted from IDS, were presented 9-month-old in two oddball conditions: standard/IDS deviant standard/ADS...
Abstract The mutual exclusivity ( ME ) assumption is proposed to facilitate early word learning by guiding infants map novel words referents. This study assessed the emergence and use of both disambiguate retain meanings across development in 18‐month‐old monolingual bilingual children (Experiment 1; N = 58), a sub‐group these again at 24 months age 2: 32). Both monolinguals bilinguals employed select referent label similar extent 18 months. At months, there were also no differences...
Here we report, for the first time, a relationship between sensitivity to amplitude envelope rise time in infants and their later vocabulary development. Recent research auditory neuroscience has revealed that plays mechanistic role speech encoding. Accordingly, individual differences infant discrimination of times could be expected relate language acquisition. A group 50 taking part longitudinal study contributed thresholds when aged 7 10 months, development was measured at 3 years....
Abstract Bilingualism is a powerful experiential factor, and its effects have been proposed to extend beyond the linguistic domain by boosting development of executive functioning skills. Crucially, recent findings suggest that this effect can be detected in bilingual infants before their first birthday indicating it emerges as result early exposure experience negotiating two systems infants' environment. However, these conclusions are based on only research studies from last decade...
The COVID-19 pandemic, and the resulting closure of daycare centers worldwide, led to unprecedented changes in children’s learning environments. This period increased time at home with caregivers, limited access external sources (e.g., daycares) provides a unique opportunity examine associations between caregiver-child activities language development. vocabularies 1742 children aged 8-36 months across 13 countries 12 languages were evaluated beginning end first lockdown their respective...
Previous research has demonstrated that being bilingual from birth is advantageous for the development of skills social cognition, executive functioning, and metalinguistic awareness due to children's extensive experience processing manipulating two linguistic systems. The present study investigated whether these cognitive advantages are also evident in sequential bilinguals, i.e., children who began acquisition their second language later childhood. Monolingual English- English-speaking...
For more than 20 years, the MacArthur–Bates Communicative Development Inventory (CDI) and its adaptations for languages other English have been used as reliable measures of infants’ toddlers’ early receptive productive vocabulary size. This article introduces OZI, Australian adaptation CDI, now normed 12- to 30-month-old children. The findings two studies are presented: (1) a comparison study that demonstrated toddlers ( N = 64) acquiring (24- 30-month-olds) obtain higher scores on OZI CDI;...
