There is substantial evidence that children's apparent omission of grammatical morphemes in utterances such as "She play tennis" and "Mummy eating" is in fact errors of commission in which contextually licensed unmarked forms encountered in the input are reproduced in a context-blind fashion. So how do children stop making such…

Children's understanding of passives of certain mental state predicates appears to lag behind passives of so-called actional predicates, an asymmetry that has posed a major empirical challenge for theories of passive acquisition. This paper argues against the dominant view in the literature that treats the predicate-based asymmetry as…

Neural network models have recently made striking progress in natural language processing, but they are typically trained on orders of magnitude more language input than children receive. What can these neural networks, which are primarily distributional learners, learn from a naturalistic subset of a single child's experience? We examine this…

The study examines phases in developing specification of grammatical marking of emergent clause-combining (CC) as indicative of children's growing ability to integrate two or more independent predications. To this end, both intra- and inter-clausal analyses were applied to all CC utterances produced by three Hebrew-acquiring children aged 2;0-3;0,…

Children seem to be relatively delayed in their comprehension of the verbal "be"-passive in English, compared to their acquisition of other constructions of object-movement such as "wh"-questions and unaccusatives. Prior work has found that children's performance on these passives can be affected by the verb's lexical…

This paper revisits the longstanding observation that children produce modal verbs (e.g., must, could) with their root meanings (e.g., abilities, obligations) by age 2, typically a year or more earlier than with their epistemic meanings (e.g., inferences). Established explanations for this "Epistemic Gap" argue that epistemic language…

Teachers and parents intuitively judge the 'level' of the child and the 'level' of the text and try to match them; they know that overestimation or underestimation of either will be met with restlessness or boredom. In this way, they have an empirical understanding of Vygotsky's ZPD--the zone of proximal development he envisioned as measuring the…

Background: A limited number of studies have analyzed grammaticality in monolingual Spanish-speaking children with specific language impairment (SLI). Most of the available data are based on bilingual speakers. Aims: To extend previous studies by doing a more detailed analysis of grammatical types in monolingual Spanish-speakers with and without…

This article aims to investigate how Dutch children may eventually converge on a targetlike distribution of "hoeven" 'need,' a modal verbal NPI (Negative Polarity Item), based on its appearance in the scope of merely some but not all of its possible licensers in the language input (i.e., the induction problem). Imitation performance was…

Two comprehension experiments were conducted to investigate whether young French-learning children (N = 76) are able to use a single number cue in subject-verb agreement contexts and match a visually dynamic scene with a corresponding verbal stimulus. Results from both preferential looking and pointing demonstrated significant comprehension in…

This study investigated neural activation patterns during verb processing in children, using fMRI (functional Magnetic Resonance Imaging). Preschool children (aged 4-6) passively listened to lists of verbs and adjectives while neural activation was measured. Findings indicated that verbs were processed differently than adjectives, as the verbs…

This study examined the productivity and representation of past-tense marking by 11 6-year-old children with and 22 children without specific language impairment (SLI). Patterns of past-tense marking as a function of a word's phonological composition and inflectional frequency were the same for the SLI children and the 11 control children matched…

Evaluation of the grammatical morphology used by 50 preschool children with specific language impairment as a function of their lexical diversity found their use of finite-verb morphology (based on number of different verbs used) and noun-related morphology lagged behind expectations in comparison to a group of normally developing preschoolers.…

This study examined the acquisition of verb particles and prepositions in language-impaired, language-matched, and age-matched preschool children (total n=42). Results indicated that the use of verb particles constituted a particularly challenging task for the language-impaired subjects relative to both the age-matched and language-matched peers.…

Grammatical development was examined for 10 children (ages 19 to 31 months) with expressive language impairments only and 10 children with both receptive- and expressive-language impairments. Group analyses did not reveal any differences between the subtypes on the Index of Productive Syntax. However, specific weakness in verb-phrase elaboration…
