Acquisition of natural language has been shown to fundamentally impact both one's ability to use the first language and the ability to learn subsequent languages later in life. Sign languages offer a unique perspective on this issue because Deaf signers receive access to signed input at varying ages. The majority acquires sign language in (early)…

Maternal education is associated with early child outcomes. However, the several mechanisms that may explain this relationship remain underexplored. Using data from 1,097 children aged 12-15 months in Chile, we estimate the maternal education gap across child cognitive and language outcomes. Following a bioecological perspective, we explore…

There are contrasting results of the association between center-based care attendance and child development, mainly related to how the time of entry and permanence in the program relates to developmental outcomes. Using latent class analysis in a nationally representative sample of Chilean children between 6 and 35 months old (n = 3,992), and…

A revised form of MacArthur-Bates Communicative Development Inventory III (SCDI-III) was presented designed for Swedish speaking children aged 2 years 6 months-4 years 0 months with the objective to give a proxy measure of their language competence. The instrument contains a vocabulary checklist with 100 words, mainly predicates, from four areas;…

Associations between type and age of entry into Norwegian universally-accessible childcare and children's behavior problems at age 3 years were examined in this study. Data from 73,068 children in the large population-based, prospective Norwegian Mother and Child Cohort Study (MoBa) were used, and included information about childcare arrangements,…

Heritage language (HL) proficiency confers developmental benefits; however, the onset of HL loss is observed among many young children from immigrant families. In this longitudinal study, transactional associations between children's HL proficiency and supportive family climate were examined in Chinese immigrant families with pre-school-aged…

This study had two aims. The first aim was to measure mental state understanding in institution-reared children by using a theory of mind (ToM) scale, and to examine the role of cultural context in sequencing of ToM acquisition. The other aim was to investigate ToM in relation to social competence and executive function (EF). Due to its pronounced…

The present research explores young children's extension of novel labels to novel animate items. Three experiments were performed by means of the intermodal preferential looking (IPL) paradigm. In Experiment 1, after repeated exposure to novel word-object associations, 24- and 36-month-olds extend novel labels on the basis of shape similarity, in…

Data from 226 adoptive and 224 nonadoptive families was used to explore the etiology of individual differences in communication development. Children's scores from the Sequenced Inventory of Communication Development (SICD) were compared with verbal and cognitive ability measures of their parents. Sibling correlations were also examined. (SKC)

A brief history of the study of language acquisition is followed by a detailed discussion of two subareas: metalinguistic thinking and the development of literacy. (MP)

There are many postulates of a relation between quality of attachment with theory of mind and language functions (e.g., de Rosnay & Hughes, 2006). The current study examined in longitudinal design how different patterns of attachment are associated with usage of internal state language at ages 17, 23, 30 and 36 months. Transcripts of mother-child…

Thirty-five children who had participated in a study of mastery motivation at one year of age were reevaluated at 3.5 years. Findings differed for boys and girls and indicated that a wide range of behaviors in the cognitive-motivational domain must be examined to find developmental continuities. (Author/CB)

Reconsiders the predominant views on the acquisition of kinship terms. Topics discussed include: (1) kinship and the ontogenesis of logic; (2) kinship and semantic development; (3) the language learner as naive theorist; (4) development and domain specificity; and (5) an alternative approach to kinship. (RJC)

Analysis of naturalistic data identified features of adult-child talk which occurred frequently at school but rarely at home. One of these features--question sequences intended to elicit an answer--was used in an intervention study and was found to promote young children's understanding of ambiguity in verbal messages. (PCB)

Children and adults were asked to place something "in front of" or "behind" a featured or nonfeatured object. Most subjects responded to the object's inherent features. A significant number of adults used the observer orientation cue. Children had more difficulty with the nonfeatured object but also used the observer…
