  • Size sound symbolism in mothers’ speech to their infants

    Open AccessCatherine Laing, Ghada Khattab et al.ARTICLEJournal of Child Language2025

    Six-month-olds infer object size based on pitch: they map high-pitched vowels onto smaller objects and low-pitched vowels onto larger objects (Peña et al., 2011). The ‘sound symbolism bootstrapping hypothesis’ (Imai & Kita, 2014) proposes that this may support understanding of word-meaning correspondences; by drawing on iconic pairings between linguistic cues and corresponding referents (e.g., higher pitch for smaller objects), infants develop un…

  • Child phonological responses to variegation in adult words

    Open AccessMarilyn Vihman, Mitsuhiko Ota et al.ARTICLEJournal of Child Language2023

    Variegation – the presence of more than one supraglottal consonant per word – is a key challenge for children as they increase their expressive vocabulary toward the end of the single-word period. Here we consider the prosodic structures of target words and child forms in English, Finnish, French, Japanese and Mandarin to determine whether children learning these languages respond similarly to the challenge or instead differ in ways related to th…

  • Quantifying Sources of Variability in Infancy Research Using the Infant-Directed-Speech Preference

    Open AccessMichael C Frank, Katie Alcock et al.ARTICLEAdvances in Methods and Practices…2020

    Psychological scientists have become increasingly concerned with issues related to methodology and replicability, and infancy researchers in particular face specific challenges related to replicability: For example, high-powered studies are difficult to conduct, testing conditions vary across labs, and different labs have access to different infant populations. Addressing these concerns, we report on a large-scale, multisite study aimed at (a) as…

  • How salient are onomatopoeia in the early input? A prosodic analysis of infant-directed speech

    Open AccessCatherine Laing, Marilyn Vihman et al.ARTICLEJournal of Child Language2017

    Onomatopoeia are frequently identified amongst infants’ earliest words (Menn & Vihman, 2011), yet few authors have considered why this might be, and even fewer have explored this phenomenon empirically. Here we analyze mothers’ production of onomatopoeia in infant-directed speech (IDS) to provide an input-based perspective on these forms. Twelve mothers were recorded interacting with their 8-month-olds; onomatopoeic words (e.g. quack ) were compa…

  • When do infants begin recognizing familiar words in sentences

    Open AccessRory A Depaolis, Marilyn Vihman et al.ARTICLEJournal of Child Language2014

    Previous studies have shown that by 11 but not by 10 months infants recognize words that have become familiar from everyday life independently of the experimental setting. This study explored the ability of 10-, 11-, and 12-month-old infants to recognize familiar words in sentential context, without experimental training. The headturn preference procedure was used to contrast passages containing words likely to be familiar to the infants with pas…

  • The dynamics of syntax acquisition

    Open AccessTamar Keren‐portnoy, Tamar Keren-Portnoy et al.ARTICLEJournal of Child Language2011

    This paper sets out to show how facilitation between different clause structures operates over time in syntax acquisition. The phenomenon of facilitation within given structures has been widely documented, yet inter-structure facilitation has rarely been reported so far. Our findings are based on the naturalistic production corpora of six toddlers learning Hebrew as their first language. We use regression analysis, a method that has not been used…

  • The role of production practice in lexical and phonological development – a commentary on Stoel-Gammon's ‘Relationships between lexical and phonological development in young children’

    Open AccessMarilyn Vihman, Manuel Gómez Ortiz et al.ARTICLEJournal of Child Language2011

    Carol Stoel-Gammon has made a real contribution in bringing together two fields that are not generally jointly addressed. Like Stoel-Gammon, we have long focused on individual differences in phonological development (e.g. Vihman, Ferguson & Elbert, 1986; Vihman, Boysson-Bardies, Durand & Sundberg, 1994; Keren-Portnoy, Majorano & Vihman, 2008). And like her, we have been closely concerned with the relationship between lexical and phonological lear…

  • From phonetics to phonology

    Open AccessTamar Keren‐portnoy, Tamar Keren-Portnoy et al.ARTICLEJournal of Child Language2009

    This study assesses the extent of phonetic continuity between babble and words in four Italian children followed longitudinally from 0 ; 9 or 0 ; 10 to 2 ; 0 – two with relatively rapid and two with slower lexical growth. Prelinguistic phonetic characteristics, including both (a) consistent use of specific consonants and (b) age of onset and extent of consonant variegation in babble, are found to predict rate of lexical advance and to relate to t…

  • Facilitation and practice in verb acquisition

    Open AccessTamar Keren‐portnoy, Tamar Keren-PortnoyARTICLEJournal of Child Language2006

    This paper presents a model of syntax acquisition, whose main points are as follows: Syntax is acquired in an item-based manner; early learning facilitates subsequent learning – as evidenced by the accelerating rate of new verbs entering a given structure; and mastery of syntactic knowledge is typically achieved through practice – as evidenced by intensive use and common word order errors – and this slows down learning during the early stages of …
