The acquisition of passives is well-studied in many languages, with evidence of crosslinguistic differences in the age at which passives are acquired. The aim of this study is to add to the existing knowledge of child acquisition of passives by providing data from Afrikaans and isiXhosa, two under-researched and typologically different languages…

While it is established that parental "wh"-questions, as a high-quality language input, are associated with child language outcome, less is known about the role of children's "wh"-questions in their language development. This study examines whether children's "wh"-questions during a dinnertime conversation are…

As early childhood education programming expands across the globe, there is an increased need to understand how features of these programs influence children's development. The composition of children's age within a classroom is one such feature, although it is much less studied than other features. Theoretical and empirical evidence suggests that…

This paper investigates how negation develops in the speech of a Turkish-speaking child in the very early stages of language acquisition. The study features the video recordings of a child between the ages of 19 and 22 months and the analyses of negative forms in the recorded data. The development of negation in parent-child interactions is…

A child's early language skills are one of the best predictors of academic success, and a number of community interventions have aimed to increase caregiver-child interactions to improve language development and related outcomes. This article describes ongoing community efforts in Tulsa, Oklahoma, and Philadelphia, Pennsylvania, aimed at enriching…

This study aimed to investigate concerns of validity and reliability in subjective ratings of age-of-acquisition (AoA), through exploring characteristics of the individual rater. An additional aim was to validate the obtained AoA ratings against two corpora -- one of child speech and one of adult speech -- specifically exploring whether words…

Critical theoretical approaches to the concept of recognition emphasise the Hegelian concept of a morally motivated struggle to obtain an identity that can be characterised as authentic. This paper takes the concept of a struggle for recognition, Erwing Goffman's concept of "passing", and the cross-disciplinary concept of languaging as…

Purpose: Previous studies with children and adults have demonstrated a "familiar talker advantage"--better word recognition for familiar talkers. The goal of the current study was to test whether this phenomenon is modulated by a child's language ability. Method: Sixty children with a range of language ability were trained to learn the…

Purpose: Previous studies showed early production precedes late perception in Cantonese tone acquisition, contrary to the general principle that perception precedes production in child language. How tone production and perception are linked in 1st language acquisition remains largely unknown. Our study revisited the acquisition of tone in…

Following a usage-based approach of language acquisition, the goal of this article is to make a detailed analysis of other and self-repairs targeting a French child's non-conventional productions between 1;09 and 4;0. The study's hypotheses were that (1) the mother would start by offering repairs and later in development use strategies to lead the…

Purpose: This study investigates the development of phase locking and frequency representation in infants using the frequency-following response to consonant-vowel syllables. Method: The frequency-following response was recorded in 56 infants and 15 young adults to 2 speech syllables (/ba/ and /ga/), which were presented in randomized order to the…

This paper describes an investigation into the function of child-directed speech (CDS) across development. In the first experiment, 10-21-month-olds were presented with familiar words in CDS and trained on novel words in CDS or adult-directed speech (ADS). All children preferred the matching display for familiar words. However, only older toddlers…

Previous developmental studies of conjunction have focused on the syntax of phrasal and sentential coordination (Lust, 1977; de Villiers, Tager-Flusberg & Hakuta, 1977; Bloom, Lahey, Hood, Lifter & Fiess, 1980, among others). The present study examined the flexibility of children's interpretation of conjunction. Specifically, when two…

Previous research on young children's knowledge of prosodic focus marking has revealed an apparent paradox, with comprehension appearing to lag behind production. Comprehension of prosodic focus is difficult to study experimentally due to its subtle and ambiguous contribution to pragmatic meaning. We designed a novel comprehension task, which…

Purpose: Frequent sounds and frequent words are both acquired at an earlier age and are produced by children more accurately. Recent research suggests that frequency is not always a facilitative concept, however. Interactions between input frequency in perception and practice frequency in production may limit or inhibit growth. In this study, we…
