This article explores the applicability of mean length of utterance (MLU) as a language assessment measure for Georgian child language, as to-date, Georgian, a morphologically rich language with numerous inflectional categories, experiences an extensive lack of instruments for early language assessment. To this end, a set of guidelines for…

Purpose: This study aimed to (a) provide speech-language pathologists and researchers with a play-based procedure to measure the expression of spoken communicative intents by children aged 3 to 4.5 years and (b) present indicators of these children's capacity to produce these intents in this context. Method: A method inspired by TRIAGE (Technique…

Purpose: Analysis of narrative language samples is a recommended clinical practice in the assessment of children's language skills, but we know little about how results from such analyses relate to overall oral language ability across the early school years. We examined the relations between language sample metrics from a short narrative retell,…

Individuals with sex chromosome trisomies (SCTs) have an increased risk of language delays and impairments. However, there are only a few data relative to their language development in early childhood. The present study aimed to investigate the preverbal skills shown by a group of 8-month-old children with SCTs to assess the presence of a possible…

This study investigated the relation between lexical development and the production of prosodic prominence in disyllabic babble and words. Monthly recordings from nine typically developing Belgian-Dutch-speaking infants were analyzed from the onset of babbling until a cumulative vocabulary of 200 words was reached. The differentiation between the…

Gestures and vocal elements interact from the early stages of language development, but the role of this interaction in the language learning process is not yet completely understood. The aim of this study is to explore gestural accompaniment's influence on the acoustic properties of vocalizations in the transition to first words. Eleven Spanish…

This volume presents the findings of a large-scale study of individual differences in spoken (and heard) language development during the school years. The goal of the study was to investigate the degree to which language abilities at school entry were stable over time and influential in the child's overall success in important aspects of…

Little research has been conducted on the development of suprasegmental characteristics of vocalizations in typically developing infants (TDI) and the role of audition in the development of these characteristics. The purpose of the present study was to examine the longitudinal development of fundamental frequency (F[subscript 0]) in eight TDI and…

Purpose: Onset of canonical babbling by 10 months of age is surprisingly robust in infancy, suggesting that there must be deep biological forces that keep the development of this key vocal capability on course. This study further evaluated the robustness of canonical babbling and other aspects of prelinguistic vocal development. Method:…

A longitudinal study of one children documents an invented language game consisting of suffixal reduplication and onset replacement. Argues that this game may more closely resemble adult rhyme. (Author/VWL)

Longitudinal studies of the application of a paraphrasing model to 18- to 28-month-olds indicated that mean length of utterance was significantly correlated with realized and paraphrased frequencies of several linguistic items in the subjects' corpora. The model was productive for examining children's corpora of speech and the linguistic…

Analysis of a complete set of word-forms produced by a one-year-old at the one-word stage found that the data showed little phonetic variability and that phonological development during the period studied (about one year) was qualitatively continuous with subsequent development. (Author/CB)

A longitudinal study examined two-year-olds' acquisition of the English auxiliary system after a six-week exposure to additional auxiliary input in varying sentence contexts. Results indicated that subjects did not significantly differ from a baseline group that did not receive additional input. (Author/CB)

Word and nonword vocalizations produced by two groups of children aged 8-28 months were studied. The first group included six children whose speech was recorded monthly for 12 months. The second group contained 21 children. In both, only spontaneous vocalizations were recorded. Each sample was examined for frequency of word and nonword forms. A…

Reports a study of two- and three-year-olds' acquisition of complex sentences with perception and epistemic verbs that took a second verb in their complements. Complement types, complementizer connectives, and the discourse contexts in which complementation occurred were specific to individual matrix verbs. (Author/CB)
