The first stage of combinatorial speech is better described as variable than uniform. Talk of variants obscures two different aspects of language (knowledge and use) and two different aspects of language development -- acquisition of the grammar (competence) and deployment of the grammar in speaking and listening (performance). Null subjects and…

Research in language development has only recently begun to focus on the inherent variability of language. Previous studies have explored at what age children begin to produce variable linguistic forms and how these forms progress through development. While children produce adult-like variation early on, some variable forms take longer to acquire…

Age of acquisition (AoA) refers to the age at which people learn a particular item and the AoA effect refers to the phenomenon that early-acquired items are processed more quickly and accurately than those acquired later. Over several decades, the AoA effect has been investigated using neuroscientific, behavioral, corpus and computational…

A number of longitudinal studies of L2 production have reported frequency effects wherein learners' produce more frequent words as a function of time. The current study investigated the spoken output of English L2 learners over a four-month period of time using both native and non-native English speaker frequency norms for both word types and word…

This paper represents a multimodal analysis of the paraverbal (prosodic and gesture) features of expressive female political speech in Latin America and Spain. The language corpus consisted of public speeches delivered by Spanish-speaking female politicians Eva Peron, Christina de Kirchner and Manuela Carmena. The article includes an overview of…

Research on the age of learning effect on second language learners' foreign accents utilizes human judgments to determine speech production outcomes. Inferences drawn from analyses of these ratings are then used to inform theories. The present study focuses on rater differences in the age of learning effect research. Three groups of raters who…

Speakers of gender-agreement languages use gender-marked elements of the noun phrase in spoken-word recognition: A congruent marking on a determiner or adjective facilitates the recognition of a subsequent noun, while an incongruent marking inhibits its recognition. However, while monolinguals and early language learners evidence this…

Background: Children who are bilingual and have speech sound disorder are likely to be under-referred, possibly due to confusion about typical speech acquisition in bilingual children. Aims: To investigate what is known about the impact of bilingualism on children's acquisition of speech in English to facilitate the identification and treatment of…

Experimental studies demonstrate that contrast helps toddlers to extend the meanings of novel adjectives. This study explores whether antonym co-occurrence in spontaneous speech also has an effect on adjective use by the child. The authors studied adjective production in longitudinal speech samples from 16 children (16-36 months) acquiring eight…

This study longitudinally investigated developmental changes in the frame of reference used by children in their gestures and speech. Fifteen children, between 4 and 6 years of age, were asked once a year to describe their route home from their nursery school. When the children were 4 years old, they tended to produce gestures that directly and…

This investigation explored the conversational practices and conversational rule-conformity of children aged four, six, and eight. Procedures included observation of the conversational behavior of children in classroom interaction among peers and a controlled laboratory investigation of the conversations of 18 children, of varying age levels, who…

Three levels of metacommunication knowledge and five factors that influence the understanding of speaker meaning in oral language were identified in pilot interviews with children and adolescents. (HOD)

This paper reviews the research on speech perception and reassesses the contribution of innate capacities versus external stimulation in conjunction with age in first- and second-language acquisition. A developmental model of speech perception is then discussed in relation to neonatal auditory perception. (Contains 86 references.) (MDM)

Comprehension of relative clauses was assessed in 10 Hebrew-speaking school-age children with syntactic SLI and in two groups of younger children with normal language development. Comprehension of subject- and object-relatives was assessed using a binary sentence-picture matching task. The findings were that while Hebrew-speaking children with…

This study examined the way medical clinicians speak about numbers in orally presenting the results of research. Presentations by a sample of eight physicians and surgeons were selected and the manner in which numerical data on the slides were referred to was analyzed. Overall in the sample, it was four times more common to speak about data on…
