This study examines whether children acquiring Tseltal (Mayan) demonstrate a noun bias -- an overrepresentation of nouns in their early vocabularies. Nouns, specifically concrete and animate nouns, are argued to universally predominate in children's early vocabularies because their referents are naturally available as bounded concepts to which…

Purpose: Assessing whether a book is relevant or suitable for use in teaching materials is not an easy and haphazard matter, various methods and theories have been offered by researchers in studying this matter. Taking a study of the context of textbooks, researchers found the urgency that textbooks are a foundation for education, socialization…

Purpose: Our goal is to understand how the different types of plural marking are understood and processed by children with cochlear implants (CIs): (a) how does salience affect the processing of plural marking, (b) how is this processing affected by the incomplete signal provided by the CIs, and (c) is it linked to individual factors such as…

Purpose: The current investigation evaluated the extent to which early noun, verb, and adjective lexicon sizes predicted later grammatical outcomes in Mandarin-speaking children with and without late language emergence (LLE) using a parent report. Method: In Study 1, the parents of 24 Mandarin-speaking children with typical language filled out the…

Korean is a classifier language in which bare nouns are not obligatorily number-marked. Children learning other classifier languages like Japanese and Mandarin are late in learning the plural morpheme. In this paper, we present two datasets that suggest that Korean plural marker "-tul" is acquired much earlier, in contrast to what has…

Purpose: This study examines whether differences in acquisition exist among the inflectional constructions of number, gender, possessive pronouns, and tense. Moreover, the study investigates whether these inflectional patterns develop with age. Method: The participants were 1,020 Arabic-speaking kindergartners from K2 and K3. Children were…

The objective of this study was to examine the development of derivational morphological structures in the productive language of Kuwaiti Arabic (KA)-speaking children. Participants were 512 typically developing Kuwaiti children aged 3;0 years to 7;11 years (243 boys and 269 girls). Five age groups at 1-year intervals were tested; each group was…

This study investigated the acquisition of word-patterns and roots in the nominal system of the spoken language of Palestinian Arabic (PA) and its distance from Standard Arabic (StA). It described, analyzed, and quantified the nominal system (roots and word-patterns) as reflected in the language corpus of Palestinian-Arab kindergarteners 3 to 6…

Given the rich bound morphology of Spoken Arabic, an attempt was made here to construct a developmental measure corresponding to the mean length utterance (MLU) in English and to morpheme-per-utterance (MPU) in Hebrew. The adaptation to Arabic resulted in a new measurement termed Arabic-MPU, that was experimentally tested on a sample of 98…

Using a habituation paradigm with a three-switch design, the present study investigated whether 20-month-old French-learning infants use noun and verb morphosyntactic cues to learn novel words in dynamic events differentially when both the agent and the action interpretations are possible. Of particular interest was whether infants' initial…

This article presents a cross-cultural comparison of the size and composition of the expressive vocabulary of young children speaking two dialectal varieties of South American Spanish. Ninety-one Peruvian and 91 Argentinian toddlers (mean age: 22.5 months), matched on gender, age and maternal education, were assessed through the respective…

We used the elicited production task to explore the production of short and long passives in 15 Mandarin-speaking preschool children with Developmental Language Disorder (DLD; aged 4;2-5;11) in comparison with 15 Typically Developing Aged-matched (TDA) children (aged 4;3-5;8) and 15 Typically Developing Younger (TDY) children (aged 3;2-4;3). This…

Previous research has highlighted the difficulty that infants have in learning to use color words. Even after acquiring the words themselves, infants are reported to use them incorrectly, or overextend their usage. We tested 146 infants from 5 different age groups on their knowledge of 6 basic color words, "red", "green",…

A previous study has shown that children use recent input to adapt their syntactic predictions and use these adapted predictions to infer the meaning of novel words. In the current study, we investigated whether children could use this mechanism to disambiguate words whose interpretation as a noun or a verb is ambiguous. We tested 2- to 4-year-old…

This study examines the quantity and quality of child-directed speech across household activities in a socioeconomically diverse sample of Argentinian Spanish-speaking children, an understudied population. Thirty children (mean: 14.3 months) and their families were audio-recorded for four hours. The middle two hours were transcribed and analysed…
