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…

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…

Children achieve their first language milestones initially in gesture and prosody before they do so in speech. However, little is known about the potential precursor role of those features later in development when children start using more complex linguistic skills. In this study, we explore how children's ability to reflect on their degree of…

It remains controversial whether children are able to process and integrate specific linguistic cues in their mental model to the same extent as adults. In the present study, a sentence continuation task was employed to determine how Italian speakers (4-, 5-, 6-year-olds and adults) interpret prosodic cues to decide which referent is more salient…

This dissertation tests a new account of rapid word learning and vocabulary growth that these processes develop as the result of attentional biases to the features of a category that are relevant to labeling/categorization, built as the result of word-learning experience within each category. Study 1 demonstrated that children's vocabulary size…

In this study, 5-year-olds and adults described scenes that differed according to whether (a) the subject or object of a transitive verb represented an accessible or inaccessible referent, consistent or inconsistent with patterns of preferred argument structure, and (b) a simple noun was sufficient to uniquely identify an inaccessible referent.…

Recent studies on the acquisition of semantics have argued that knowledge of the universal quantifier is adult-like throughout development. However, there are domains where children still exhibit non-adult-like universal quantification, and arguments for the early mastery of relevant semantic knowledge do not explain what causes such…

Data from 492 Italian infants (8-18 months) were collected with the parental questionnaire MacArthur Bates Communicative Development Inventories to describe early actions and gestures (A-G) "vocabulary" and its relation with spoken vocabulary in both comprehension and production. A-G were more strongly correlated with word comprehension…

This study examined on-line processing of Swedish sentences in a grammaticality-judgement experiment within the framework of the Competition Model. Three age groups from 6 to 11 and an adult group were asked to detect grammatical violations as quickly as possible. Three factors concerning cue cost were studied: violation position (early vs. late),…

The relation of social and linguistic input measures to early vocabulary development was examined in 30 low-income African American mother-infant pairs. Observations were conducted when the child was 0 years, 1 month (0;1), 0;4, 0;8, 1;0, 1;6, and 2;0. Maternal input was coded for word types and tokens, contingent responsiveness, and…

The purpose of this article is to examine the language of girls and boys between 8 and 30 months of age, using the Quebec French version of The MacArthur Communicative Development Inventories. The findings from this parental report measure confirm those of earlier research, which showed the linguistic superiority of girls over boys at a young age.…

Little research has been conducted on the development of suprasegmental characteristics of vocalizations in typically developing infants (TDI) and the role of audition in the development of these characteristics. The purpose of the present study was to examine the longitudinal development of fundamental frequency (F[subscript 0]) in eight TDI and…

In six analyses using the Child Language Data Exchange System known as CHILDES, we explored whether and how parents and their 1.5- to 5-year-old children talk about writing. Parent speech might include information about the similarity between print and speech and about the difference between writing and drawing. Parents could convey similarity…

Two experiments examined young children's sensitivity to linguistic contexts in which particular function morphemes occur. Results showed that children who did not produce articles in spontaneous speech were able to distinguish between sentences, verbally presented in picture identification tasks, that contained grammatical articles and those that…

This study examined the effects of being born very preterm on children's early language development using prospective longitudinal data from a representative regional cohort of 90 children born very preterm (gestational age less than 33 weeks and/or birth weight less than 1,500 grams) and a comparison sample of 102 children born full term…
