Cross-linguistic studies describing the syllabic structures of babbling productions agree on the high prevalence of the CV structure, but few have addressed the other types of syllables emerging during this pre-linguistic stage. However, studying the evolution of the distribution of syllabic structures during babbling would make it possible to…

By 12 months of age, infants exhibit behavioral sensitivity to sound symbolism (e.g. sound-shape correspondences) when they hear universally sound symbolic pseudowords (e.g. "bouba," "kiki"). Here, we investigated whether infant's sensitivity to sound-shape correspondences is affected when they hear language-specific sound…

Non-tone language infants' native language recognition is based first on supra-segmental then segmental cues, but this trajectory is unknown for tone-language infants. This study investigated non-tone (English) and tone (Thai) language 6- to 10-month-old infants' preference for English vs. Thai one-syllable words (containing segmental and tone…

Crosslinguistic research into language development reveals that typological features determine children's developmental patterns to a large extent. The present study examines the early morphological development in the verb inflectional paradigm in Bangla. Data from the first 6 months since the emergence of two-word combinations were collected from…

Previous research indicates that infant-directed speech (IDS) is usually slower than adult-directed speech (ADS) and mothers prefer placing a focused word in isolation or utterance-final position in (English) IDS, which may benefit word learning. This study investigated the speaking rate and word position of IDS in two typologically-distinct…

Onomatopoeia are disproportionately high in number in infants' early words compared to adult language. Studies of infant language perception have proposed an iconic advantage for onomatopoeia, which may make them easier for infants to learn. This study analyses infants' early word production to show a phonological motivation for onomatopoeia in…

In learning language, children must discover how to interpret the linguistic significance of phonetic variation. On some accounts, receptive phonology is grounded in perceptual learning of phonetic categories from phonetic distributions drawn over the infant's sample of speech. On other accounts, receptive phonology is instead based on phonetic…

The early relationship between children's emerging articulatory abilities and their capacity to process speech input was investigated, following recent studies with English-learning infants. Twenty-six monolingual Italian-learning infants were tested at 6 months (no consistent and stable use of consonants, or vocal motor schemes [VMS]) and at the…
