This study explored the electrophysiology underlying intonational phrase processing at different stages of syntax acquisition. Developmental studies suggest that children's syntactic skills advance significantly between 2 and 3 years of age. Here, children of three age groups were tested on phrase-level prosodic processing before and after this…

This study investigates prosodic (noun length) and lexical-semantic (animacy) influences on determiner use in the spontaneous speech of three children acquiring French, Austrian German and Dutch. In support of typological and language-specific hypotheses from the Germanic-Romance contrast, an advantage of monosyllabic nouns and of inanimate nouns…

This study presents evidence suggesting that electrophysiological responses to language-related auditory stimuli recorded at 46 weeks postconceptional age (PCA) are associated with language development, particularly in infants with periventricular leukomalacia (PVL). In order to investigate this hypothesis, electrophysiological responses to a set…

Reading with an adult plays an important role in developing children's oral language skills, phonological awareness and print knowledge. Parental reading aloud is also an indicator of children's later academic success, which suggests that the practice may be further linked to children's development of broader academic skills and behaviour, such as…

While it is well known that languages have different phonemes and phonologies, there is growing interest in the idea that languages may also differ in their "phonetic setting". The term "phonetic setting" refers to a tendency to make the vocal apparatus employ a language-specific habitual configuration. For example, languages may differ in their…

Recognizing word boundaries in continuous speech requires detailed knowledge of the native language. In the first year of life, infants acquire considerable word segmentation abilities. Infants at this early stage in word segmentation rely to a large extent on the metrical pattern of their native language, at least in stress-based languages. In…

When addressing infants, many adults adopt a particular type of speech, known as infant-directed speech (IDS). IDS is characterized by exaggerated intonation, as well as reduced speech rate, shorter utterance duration, and grammatical simplification. It is commonly asserted that IDS serves in part to facilitate language learning. Although…

Early prosodic development (f[subscript 0] variation) was systematically measured in Mandarin-learning infants at the transition from babbling to producing first words. Spontaneous vocalizations of twenty-four infants aged 0;7 to 1;6 were recorded in 45-minute sessions. The speech production of twenty-four caregivers was also audio-recorded during…

In language learning, infants are faced with the challenge of decomposing continuous speech into relevant units, such as syntactic clauses and words. Within the framework of prosodic bootstrapping, behavioral studies suggest infants approach this segmentation problem by relying on prosodic information, especially on acoustically marked…

This study describes the development of emerging intonation in six children who had received a cochlear implant (CI) before the age of 3 years. At the time their implant was activated, the children ranged in age from 11-37 months. Spontaneous longitudinal speech samples were recorded from 30-minute sessions in which the child interacted with his…

Word segmentation, that is, discovering the boundaries between words that are embedded in a continuous speech stream, is an important faculty for language learners; humans solve this task partly by calculating transitional probabilities between sounds. Behavioral and ERP studies suggest that detection of sequential probabilities (statistical…

Two experiments tested whether phonological phrase boundaries constrain online syntactic analysis in French. Pairs of homophones belonging to different syntactic categories (verb and adjective) were used to create sentences with a local syntactic ambiguity (e.g., [le petit chien "mort"], in English, the "dead" little dog, vs.…

Previous studies have suggested that intonation development in infants and toddlers reflects an interaction between physiological and linguistic influences. The immediate background research for this study, however, was based on vocalizations that were only one syllable in length. By extending the analysis to polysyllabic utterances, the present…

Maternal depression significantly influences parent-child interactions. While the existence of this impact is well established during playtime, little research has been conducted on the way that maternal depression relates to shared book reading. This is a particularly important activity because it relates to children's language and literacy…

Two studies explored the nature of phonological awareness (PA) in Chinese. In Study 1, involving 146 children, awareness of phoneme onset did not differ from chance levels at ages 3-5 years in preschool but increased to 70% correct in first grade, when children first received phonological coding (Pinyin) instruction. Similarly, tone awareness was…
