Computational cognitive modeling is a tool we can use to evaluate theories of syntactic acquisition. Here, I review several models implementing theories that integrate information from both linguistic and non-linguistic sources to learn different types of syntactic knowledge. Some of these models additionally consider the impact of factors coming…

Cognitive development is often characterized in terms of discontinuities, but these discontinuities can sometimes be apparent rather than actual and can arise from continuous developmental change. To explore this idea, we use as a case study the finding by Stager and Werker (1997) that children's early ability to distinguish similar sounds does…

Most theories of learning would predict a gradual acquisition and refinement of skills as learning progresses, and while some highlight exponential growth, this fails to explain why natural cognitive development typically progresses in stages. Models that do span multiple developmental stages typically have parameters to "switch" between…

This longitudinal study examined developmental links between closeness in teacher-child relationships and children's receptive language ability from the end of the preschool years into the early elementary years, while controlling for changes in peer interaction quality and child behavioral functioning. The sample included children and their…

Objectives: This research sought to determine if the language delay (LD) of severely neglected children under 3 years old was better explained by a cumulative risk model or by the specificity of risk factors. The objective was also to identify the risk factors with the strongest impact on LD among various biological, psychological, and…

Computational models have played a central role in the debate over language learnability. This article discusses how they have been used in different "stances", from generative views to more recently introduced explanatory frameworks based on embodiment, cognitive development and cultural evolution. By digging into the details of certain specific…

Presents a hybrid ACT-R model that shows U-shaped learning of the English past tense without direct feedback, changes in vocabulary, or unrealistically high rates of regular verbs. Illustrates that the model can learn the default rule, even if regular forms are infrequent. Shows that the model can explore the question of why there is a distinction…

Introduces the time window, a construct that characterizes when and how the integration of knowledge occurs, which is fundamental to the development of cognition. Describes the characteristics of time windows, evidence supporting them, factors that affect them, research illustrating their generality, and theoretical and applied implications. (ET)

Details findings indicating that most early linguistic competence is item based. Maintains that language development proceeds without evidence of system-wide syntactic categories, schemas, or parameters. Suggests that findings are not easily explained by the development of children's skills of linguistic performance, pragmatics, or other external…

Learning invariably proceeds by relating new facts to the already familiar and present in the conceptual structure. In the context of FL study the familiar is, of course, the student's mother tongue. Drawing on the learner's L[subscript 1] (or another mastered tongue) and showing comparisons and contrasts between the languages mirrors, facilitates…

Toddlers' symbolic understanding of iconic models was assessed through 2 comprehension-based tasks: 1 based on looking and 1 requiring manual selection of the target object. Toddlers received either iconic models or photographs of models as the symbolic referent. Overall, 18-month-olds performed poorly, and both 22- and 26-month-olds performed…

Piaget's research on the processes and products of cognitive and representational development in early childhood is employed to outline the bases of early language development. The processes of assimilation and accommodation, leading to horizontal decalage; empirical and reflective abstraction, resulting in schemas and schemes; as well as…

This paper presents a neo-Piagetian model for examining the development of early communication and language skills; discusses its origins in the current developmental literature, and provides a brief overview of a preliminary version of 12 scales developed for assessing communicative development based on the model. The model attempts to provide a…

Presents emergentist coalition theory of language development characterizing lexical acquisition as the emergent product of cognitive constraints, social-pragmatic factors, and global attentional mechanisms. Details 12 experiments with 12- to 25-month-olds using the development of reference as test case of the theory. Presents evidence that…

Deaf children's thought processes are analyzed in regard to J. Piaget's theory of cognitive development. (Author)
