We provide an account of the developmental trajectory of Emirati Arabic negation particles. We treat the non-verbal predicate negator (NVPN) "mub" as a negative copula, in contrast to the verbal predicate negator (VPN) "maa," which encodes sentential negation in verbal and existential contexts. The analysis is supported by…

I review the classic literature in generative grammar and Marr's three-level program for cognitive science to defend the Evaluation Metric as a psychological theory of language learning. Focusing on well-established facts of language variation, change, and use, I argue that optimal statistical principles embodied in Bayesian inference models are…

Studies of (TD) and (ING) in King of Prussia (Pennsylvania) families show that children have matched their parents' patterns of variation by age seven, before many categorical phonological and grammatical rules can be established. Some dialect-specific and socially marked constraints are acquired before constraints with general articulatory…

Idioglossia is a private communication system, most commonly occurring in twins. It also occurs between singletons and between other siblings of multiple births. These communication systems range from manual gestures to a fully developed vocal language with its own grammar. The literature of idioglossia is scanty and largely anecdotal. Much of the…

Provides an overview of current research on grammatical, phonological, semantic, and pragmatic development in African American English child language, as opposed to adult or adolescent language, and discusses the implications of these findings for professionals involved in second-dialect instruction, speech-language assessment, or intervention…

This paper attempts to show the relationship between variable rules and more widely used psycholinguistic constructs such as amalgams and schemas, and to point out how variationists' methods can be useful in the study of language acquisition. The traditional rule, the rule for forming the past tense of regular verbs in English, is discussed as it…

Research on child language acquisition should distinguish between different possible causes of variation and not just attribute variation to individual variation. An alternative analysis using a different methodology can show that children's patterns of acquisition are actually relatively similar. (Author/CB)
