Approximately 228,000 children from birth to age 3 are affected by a disability. Developmental challenges may include severe, chronic disabilities that can begin at birth and last a lifetime. Delayed speech and language are the most common types of developmental delays among infants and toddlers. Many of these children are at risk for later…

This study explored Mandarin-speaking mothers' referential choice in relation to informativeness. The data consisted of two Mandarin-speaking mothers' natural conversation with their children, collected when the children were between the ages of 2;2 and 3;1. The subject and object arguments of the mothers' utterances were coded for the categories…

How do children as young as 2 years of age know that numerals, like "one," have exact interpretations, while quantifiers and words like "a" do not? Previous studies have argued that only numerals have exact lexical meanings. Children could not use scalar implicature to strengthen numeral meanings, it is argued, since they fail to do so for…

This paper sets out to show how facilitation between different clause structures operates over time in syntax acquisition. The phenomenon of facilitation within given structures has been widely documented, yet inter-structure facilitation has rarely been reported so far. Our findings are based on the naturalistic production corpora of six toddlers…

In this study, observed maternal positive engagement and perception of work-family spillover were examined as mediators of the association between maternal nonstandard work schedules and children's expressive language outcomes in 231 African American families living in rural households. Mothers reported their work schedules when their child was 24…

This study examined the joint effects of home environment and center-based child care quality on children's language, communication, and early literacy development, while also considering prior developmental level. Participants were 95 children (46 boys), assessed as toddlers (mean age = 26.33 months; Time 1) and preschoolers (mean age = 68.71…

Poor language skills can have a negative effect on a developing child if not identified early. Current strategies to identify families with children who may need additional support are limited, and may not detect child language problems before they become entrenched. The present study explores observed indices of parental language as a means of…

Relations between mothers' tendency to comment appropriately on their 8-month-olds' internal states (mind-mindedness) and children's behavioral difficulties (Strengths and Difficulties Questionnaire) at ages 44 and 61 months were investigated in a socially diverse sample (N = 171, 88 boys). Controlling for maternal depressive symptoms, perceived…

Dynamic skill theory was utilized to explain the multiple mechanisms and mediating processes influencing development of self-regulatory and language skills in children at 14, 24, and 36 months of age. Relations were found between family risks, parenting-related stresses, and parent-child interactions that contribute either independently or through…

This study investigated vocabulary size and vocabulary composition in Greek children aged 1 ; 6 to 2 ; 11 using a Greek adaptation of Rescorla's Language Development Survey (LDS; Rescorla, 1989). Participants were 273 toddlers coming from monolingual Greek-speaking families. Greek LDS data were compared with US LDS data obtained from the…

This study focuses on a trilingual toddler's ability to differentiate her Tagalog, Spanish and English productions on phonological/phonetic grounds. Working within the articulatory phonology framework, the word-initial segments produced by the child in Tagalog, Spanish and English words at age 1;10 were narrowly transcribed by two researchers and…

The Hebrew Parent Questionnaire for Communication and Early Language (HPQ-CEL) was administered by 154 parents of Hebrew-speaking toddlers aged 1 ; 0 to 1 ; 3 (77 boys, 77 girls). The Questionnaire guided parents in observing and rating their toddlers in six contexts at home. The study aimed to identify inter-correlations between toddlers'…

Parents' use of conventional versus unconventional labels with their two- (n=12), three- (n=12) and four-year-old children (n=12) was assessed as they talked about objects that were either known or unknown to them. For known objects, parents provided typical conventional labels casually during the conversation. For unknown objects, parents were…

This paper investigated children's ability to use syntactic structures to infer semantic information. The particular syntax-semantics link examined was the one between transitivity (transitive/intransitive structures) and telicity (telic/atelic perspectives; that is, boundedness). Although transitivity is an important syntactic reflex of telicity,…

When they see a familiar object and an unfamiliar one, and are asked to select the referent of a novel label, children usually choose the unfamiliar object. We asked whether this "disambiguation effect" reflects an expectation that each object has just one label (mutual exclusivity), or an expectation about the intent of the speaker who uses a…
