We investigate the development of word order in German children's spontaneous production of complement clauses. From soon after their second birthday, young German children use both verb final complements with complementizers and verb-second complements without complementizers. By their third birthday they use both kinds of complement clauses with…

This study focused on the attainment of Theory of Mind (ToM) in children (aged 6 to 13) with complex communication needs who used augmentative and alternative communication (AAC). The AAC group (n = 14) was matched to a younger group, without disabilities, vis-a-vis nonverbal mental age. A second comparison group consisting of children with mild…

Purpose: The present study examined the nature of concurrent and predictive associations between conversational language use and reading development during early school-age years. Method: Language and reading data from 380 twins in the Western Reserve Reading Project were examined via phenotypic correlations and multilevel modeling on exploratory…

This study examines how spontaneous interests in people and in objects relate to joint engagement in typically developing toddlers and young children with autism or Down syndrome. Ratings of interests were made repeatedly during intermissions in a laboratory-based protocol focused on caregiver-child interactions. Interests were moderated by…

Purpose: Although conversational recasting has been a generally successful treatment approach, the precise factors that influence children's learning through recasts are not yet understood. In this study, we examined details of the relationship between child utterance and clinician utterance that seemed likely to influence learning. Method: Three…

For socially appropriate communication, speakers must command a variety of linguistic styles, or "registers", that vary according to social context and social relationships. This study examined preschool children's ability to use a speaker's register choice to infer the identity of their addressee. Four-year-olds could draw correct inferences…

This study examined how children use and understand various forms of irony (sarcasm, hyperbole, understatement, and rhetorical questions) in the context of naturalistic positive and negative family conversations in the home. Instances of ironic language in conversations between mothers, fathers, and their two children (M[subscript ages] = 6.33 and…

Past research has uncovered a surprising paradox: Although 14-month-olds have exquisite phonetic discrimination skills (e.g., distinguishing [b] from [d]), they have difficulty using phonetic detail when mapping "novel" words to objects in laboratory tasks (confusing "bin" and "din"). While some have attributed infants' difficulty to immature word…

Studies indicate that language impairment that cannot be accounted for by factors such as below-average non-verbal ability, hearing impairment, behaviour or emotional problems, or neurological impairments affects some 6% of school-age children. Language impairment with a receptive language component is more resistant to intervention than specific…

This study examines the link between distributional patterns in the input and infants' acquisition of non-adjacent dependencies. In two Headturn Preference experiments, Dutch-learning 24-month-olds (but not 17-month-olds) were found to track the remote dependency between the definite article "het" and the diminutive suffix…

We examined developing bilinguals' use of animacy and word order cues during sentence interpretation tasks administered in each of their languages. Participants were 6- to 8-year-old children who learned Vietnamese as a first language and English as a second language (n = 23). Participants listened to simple sentences and identified the agent or…

Conflicting reports of language ability in Williams syndrome (WS) are confusing and may hinder accurate clinical decisions with respect to therapeutic services and educational placements for children with WS.This longitudinal case study examined the acquisition of regular and irregular past tense verbs in a child with WS. The development of…

The aim of this article is to give an up-to-date picture of study of the role of the background languages (the first language, L1, and the second language, L2) in third language (L3) acquisition, mainly in the two areas of vocabulary and syntax. These seem to be the two linguistic levels on which there has so far been most research concerning…

In this paper we discuss a computational cognitive model of children's poor performance on pronoun interpretation (the so-called Delay of Principle B Effect, or DPBE). This cognitive model is based on a theoretical account that attributes the DPBE to children's inability as hearers to also take into account the speaker's perspective. The cognitive…

This study compared segmental distribution patterns for consonants and vowels in English infant-directed speech (IDS) and adult-directed speech (ADS). A previous study of Korean indicated that segmental patterns of IDS differed from ADS patterns (Lee, Davis & MacNeilage, 2008). The aim of the current study was to determine whether such differences…
