Background and Aims: This longitudinal study investigated the language skills, phonological working memory and lexical-tone perception of Mandarin-speaking late-talkers (LTs) and those with typical language development (TLD) at 27 months, while also examining their connections with novel word-referent mapping (W-R mapping) through eye-tracking at…

Purpose: Pragmatics is receiving much attention in both the fields of developmental and clinical psychology; however, there is a dearth of instruments to assess pragmatic abilities specifically among young toddler-age children. The aim of the current study was to test the psychometric properties of the Italian version of the Language Use Inventory…

Measuring individual differences in children's emerging language abilities is important to researchers and clinicians alike. The 2 most widely used methods for assessing children's vocabulary both have limitations: Experimenter-administered tests are time-consuming and expensive, and parent questionnaires have only been designed for children up to…

In this study we evaluated the predictive validity of conceptual scoring. Two independent samples of Spanish-speaking language minority preschoolers (Sample 1: N = 96, mean age = 54.51 months, 54.3% male; Sample 2: N = 116, mean age = 60·70 months, 56.0% male) completed measures of receptive, expressive, and definitional vocabulary in their first…

This paper explores the concurrent and predictive validity of the long and short forms of the Galician version of the MacArthur-Bates CDI (IDHC). Forty-two Galician-speaking children were longitudinally evaluated at age 1 ; 6, 2 ; 0 and 4 ; 0. On the first two occasions, the subjects' vocabulary and grammar skills were assessed through the IDHC.…

Few classroom measures of English language proficiency have been evaluated for reliability and validity. This research examined the concurrent and predictive validity of an oral language test, titled A Developmental English Language Proficiency Test (ADEPT), and the relationship to the California English Language Development Test (CELDT) in the…

The purpose of this study was to explore patterns of within-group variability in the emergent literacy skills of preschoolers who are at risk for academic difficulties. We used the person-centered approach of cluster analysis to identify profiles of emergent literacy skills, taking into account both oral language and code-related skills.…

Purpose: The purpose of this study was to examine the predictive validity of a collection of prelinguistic skills measured longitudinally in the 2nd year of life to language outcome in the 3rd year in children with typical language development. Method: A collection of prelinguistic skills was assessed in 160 children early (M = 14.31 months; SD =…
