We present a neural network model of referent identification in a visual world task. Inputs are visual representations of item pairs unfolding with sequences of phonemes identifying the target item. The model is trained to output the semantic representation of the target and to suppress the distractor. The training set uses a 200-word lexicon…

We present a hierarchical Bayesian framework for modeling the acquisition of verb argument constructions. It embodies a domain-general approach to learning higher-level knowledge in the form of inductive constraints (or overhypotheses), and has been used to explain other aspects of language development such as the shape bias in learning object…

This paper reports progress in developing a computer model of language acquisition in the form of (1) a generative grammar that is (2) algorithmically learnable from realistic corpus data, (3) viable in its large-scale quantitative performance and (4) psychologically real. First, we describe new algorithmic methods for unsupervised learning of…

There are numerous models of how speech segmentation may proceed in infants acquiring their first language. We present a framework for considering the relative merits and limitations of these various approaches. We then present a model of speech segmentation that aims to reveal important sources of information for speech segmentation, and to…

Recent work on the acquisition of number words has emphasized the importance of integrating linguistic and developmental perspectives [Musolino, J. (2004). The semantics and acquisition of number words: Integrating linguistic and developmental perspectives. "Cognition 93", 1-41; Papafragou, A., Musolino, J. (2003). Scalar implicatures: Scalar…

Focuses on nativist theories of language learning and how they apply to second-language acquisition (SLA). The article is seeking a nativism that goes beyond the scope of Universal Grammar and explains the human cognitive capacity for language learning, the learning of all language structures found in natural languages, and SLA. (95 references)…

Few models appropriately or adequately describe the literacy development experiences of children with atypical communication development, such as those with language impairment or severe disabilities. In this paper, the Interactive-to-Independent Model of literacy development is presented, influenced primarily by Vygotsky's seminal theories of…

Discusses "cued shadowing," during which subjects listen to pairs of words or sentences and repeat a target word signalled by a cue. Rapid semantic and grammatical priming effects have been observed with this technique, both with word and sentence contexts and at different positions within sentence contexts, in normal children and adults, and in…

Notes that in a typical word monitoring paradigm, subjects monitor ongoing language input for a pre-designated target word and that independent variables include the nature and position of the target word and the context in which it is embedded. Also notes that forms of this task are suitable for studies with young children and with individuals…

Examines the scope of pedagogic discourse, which involves the operation of a set of principles by which persons are apprenticed into ways of working valued in a culture. A pedagogic discourse is realized in two sets of language choices: (1) those connected with the goals of the teaching-learning activity, and (2) those concerning the content to be…

Describes a mispronunciation detection task, in which listeners' sensitivity to deviations in speech is measured by their pressing a button upon hearing a mispronounced word in lists or sentences. Notes that reaction times and miss rates indicate the effects of position of a misplaced phoneme in a word, the size of the phonemic deviation, lexical…

Models the spread of linguistic change by taking account of the ages of the acquirers and transmitters of change. The article focuses on three interlocutor combinations: parent-infant/young child, peer group-preadolescent and older adolescent/adult-adolescent. Findings suggest that borrowings are the easiest to acquire, while lexically…

Overviews a bilingual program serving urban schoolchildren who come from Arabic-speaking homes. The article describes the mission of the program as the preparation of students, in close cooperation with their families, to become contributing citizens in a changing society by providing a challenging curriculum to develop knowledge and a sense of…
