Iterated learning models of language evolution have typically been used to study the emergence of language, rather than historical language change. We use iterated learning models to investigate historical change in the accent classes of two Korean dialects. Simulations reveal that many of the patterns of historical change can be explained as…

Background: The study aimed to explore to what extent variables associated with lexical and sublexical spelling processes predicted single word spelling ability and whether patterns of lexical and sublexical processes were different across ages. Methods: Beginning (mean age 7 years, N=144) and advanced (mean age 9 years, N=114) English-speaking…

Presents a case study of the babbling monologues produced by a Dutch child in the six weeks following acquisiton of the first word, which shows that this child's word production and his concurrent babbling are very much related. Concludes that word production influences the course of babbling and vice versa. (SED)

Describes an unusual phonological pattern exhibited by a child aged two years that involves the production of word-final strident continuants in words whose adult forms contain these features in initial, rather than final, position (e.g., ops for soap). (13 references) (GLR)

This case study investigated whether patterns obtained from elicited speech also hold for conversational data. A longitudinal corpus of spontaneous/natural speech from an adult first-language Spanish learner of second-language Swedish is studied. (Author/VWL)

Presents a longitudinal case study of a child with a phonological disorder. Demonstrates an asymmetrical pattern of consonant cluster development with two different reduction strategies. Argues that the child first represents all clusters as single underlying units, later representing only certain clusters as single units. Formulated within…

A mother's interactions with her young daughter were studied with special emphasis placed upon the frequencies of linguistically instructional input and the strategies employed to provide this information. The girl was between 18 and 28 months old and her mean length of utterance (MIU) was between 1.5 and 4.3 morphemes. Only maternal input was…

An interactionist-discovery theory of child phonology is proposed based on the following tenets: children invent their own phonological rules, and phonetic mastery is not automatically or generally in step with learning about phonemic contrasts. When a child learns the sound pattern of a language, there is constant interaction between the…

This article introduces a whole-word approach to phonological analysis and demonstrates the approach by conducting an analysis and outlining treatment recommendations for a child with phonological disability. Rationale for using a whole-word approach and also for defining phonological typologies are presented, along with four components of a…

This article compares different claims that have been made concerning acquisition by transitional rule-based derivation theories and by optimality theory. Case studies of children with phonological delays are examined. Error patterns are argued to be implicationally related and optimality theory is shown to offer a principled explanation.…

A case study investigated the emergence of language and language concepts in a bilingual child, a girl aged 16 months to 6 years, 7 months. Observations were made by the child's parents and relatives in the child's home where the mother spoke Finnish and the father English. The report summarizes developments in phonology, morphology, word-level…

An ongoing longitudinal study, 15 years old at the time of publication, is reported. It is a sociolinguistic, developmental study of the acquisition of two languages, Spanish and English, by a boy from birth, with data drawn from direct observation and occasional tape recordings of speech. An introductory chapter outlines the objectives and method…
