To learn new words, particularly verbs, child learners have been shown to benefit from the linguistic contexts in which the words appear. However, cross-linguistic differences affect how this process unfolds. One previous study found that children's abilities to learn a new verb differed across Korean and English as a function of the sentence in…

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…

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-word repetition tasks are widely used to assess phonological short-term memory (PSTM). Results of previous research on the performance of monolingual and bilingual children in PSTM tasks are inconclusive. Although in some studies bilinguals did outperform monolinguals in the repetition of non-words, most studies reported comparatively weak…

A good deal of research purports that bilingualism has a positive effect on some aspects of cognitive functioning. However, this effect is not consistent, and little research examines trajectories of cognitive skill development in bilingual children. Moreover, it remains unclear whether different types of bilingualism impact how cognitive…

Prior work demonstrated that toddlers can learn words from a speaker with a foreign accent and generalize that learning to the native accent when the accented variation does not cross phoneme boundaries. The current study explores the situation in which a vowel in the foreign accent is produced such that it could be confused with a different…

The present study investigated the effect of classroom-based syntactic training on children's abilities to produce passive sentences. Thirty-three monolingual English children (mean age 5;2), were involved in passive-voice training based on storytelling sessions within a priming design. The training was delivered in a classroom setting, with two…

The current study examined the effect of speaker variability on children's cross-situational word learning (XSWL). The study also examined the role of bilingual experience and sustained attention. Forty English monolingual children and 40 Spanish-English bilingual children ages 4-7 completed a XSWL task in a Single Speaker Condition and a Multiple…

Maternal scaffolding and four-year-old children's linguistic skills were examined during toy play. Participants were 21 American-English monolingual and 21 Thai monolingual mother-child dyads. Results revealed cross-cultural differences in conversation styles between the two groups. American dyads adopted a high-elaborative style relative to Thai…

Bilingual children are often exposed to non-native speech through their parents. Yet, little is known about the relation between bilingual preschoolers' speech production and their speech input. The present study investigated the production of voice onset time (VOT) by Dutch-German bilingual preschoolers and their sequential bilingual mothers. The…

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…

One of the first challenges facing the young language learner is the task of segmenting words from a natural language speech stream, without prior knowledge of how these words sound. Studies with younger children find that children find it easier to segment words from fluent speech when the words are presented in infant-directed speech, i.e., the…

Although children may productively use concrete nouns after limited exposure, complete mastery of adult-like patterns of noun usage can take up to 14 years. We evaluated whether a transition from universal to language-specific naming is part of the refinement in later lexical development, and we compared how this refinement plays out in…

This study tested the effect of Spanish-accented speech on sentence comprehension in children with different degrees of Spanish experience. The hypothesis was that earlier acquisition of Spanish would be associated with enhanced comprehension of Spanish-accented speech. Three groups of 5-6-year-old children were tested: monolingual…

This study investigated the long-term effect of classroom-based input manipulation on children's use of subordination in a story re-telling task; it also explored the role of receptive vocabulary skills and expressive grammatical abilities in predicting the likelihood of priming. During a two-week priming phase, 47 monolingual English-speaking…
