Despite its importance in the development of children's skills of social cognition and communication, very little is known about the ontogenetic origins of the pointing gesture. We report a training study in which mothers gave children one month of extra daily experience with pointing as compared with a control group who had extra experience with…

Language development in typically developing children has a very predictable pattern beginning with crying, cooing, babbling, and gestures along with the recognition of spoken words, comprehension of spoken words, and then one word utterances. This predictable pattern breaks down for children with language disorders. This article will discuss…

The present paper generally reviews the history of second language (L2) researchers' efforts in an attempt to find such an index and the possible reasons for the difficulties in establishing the developmental index from both the theoretical and the empirical viewpoints. Two contradictory views--interlanguage theory and emergentism--can finally be…

This dissertation is a first look at English-speaking children's acquisition of the syntax of the partitive. It presents four experiments that contrast three types of structures and examines how they interact with adjectival modification: the partitive, the pseudopartitive and complex nouns with prepositional adjuncts. The experimentation…

Purpose: The question of how and when English-speaking children acquire auxiliaries is the subject of extensive debate. Some researchers posit the existence of innately given Universal Grammar principles to guide acquisition, although some aspects of the auxiliary system must be learned from the input. Others suggest that auxiliaries can be…

Use of precise consonantal information while learning new words has been established for onset consonants in previous studies, which showed that infants as young as 16 to 20 months of age can simultaneously learn two new words that differ only by a syllable-initial consonant (Havy & Nazzi, 2009; Nazzi, 2005; Nazzi & New, 2007; Werker, Fennell,…

The notion of language as a complex adaptive system has been conceived within an agent-based framework, which highlights the significance of individual-level variation in the characteristics and contextual circumstances of the learner/speaker. Yet, in spite of this emphasis, currently we know relatively little about the interplay among language,…

This article is concerned with how meaning potential, in particular an individual's personalized meaning potential, emerges from acts of meaning. This happens during different time frames: logogenetic--the creation of meaning in text; ontogenetic--the learning of a personalized meaning potential; and phylogenetic--the evolution of the collective…

This study examines word order differentiation in early trilingual development through an analysis of the combinations produced by a Tagalog-Spanish-English trilingual child with an MLU of less than 1.5. Same- and mixed-language combinations were tracked down from diary data and weekly recordings to assess (i) whether word order significantly…

This study examined receptive and expressive vocabulary and grammar achievement of French-speaking children (n = 27) who received a cochlear implant (CI) between the age of 1 and 2. Standardized measures of language achievement were administered and the language levels attained by children with CIs were compared with that of the normative sample…

We test the claim that acquiring a mass-count language, like English, causes speakers to think differently about entities in the world, relative to speakers of classifier languages like Japanese. We use three tasks to assess this claim: object-substance rating, quantity judgment, and word extension. Using the first two tasks, we present evidence…

This program evaluation study addressed the struggle of local elementary school speech-language pathologists (SLPs) in a school district to provide evidence-based intervention in language for students below grade level as required by the U.S. Department of Education. Recently, Language Lab™ was published to address the needs of oral language…

This longitudinal randomized-control trial investigated the effectiveness of scientifically based reading instruction for students with IQs ranging from 40 to 80, including students with intellectual disability (ID). Students were randomly assigned into treatment (n = 76) and contrast (n = 65) groups. Students in the treatment group received…

This study investigates early childhood educators' language training competence that is required to support children's linguistic development. Hundred and forty-four early-years-professionals in Germany completed a computer-based assessment. We first tested knowledge of linguistic topics (e.g. morpho-syntax, developmental stages). Second, we…

In this article we report on the development of an interactive open source extensible software, dubbed "The 7 Keys of the Dragon," for the teaching/learning of Albanian and Russian to students (9-12 years old) with the respective languages as their heritage languages. Based on the assumption that games in language learning are associated…
