Developmental psychology focuses on how psychological constructs change with age. In cognitive development research, however, the specifics of this emergence is often underspecified. Researchers often provisionally assume linear growth by including chronological age as a predictor in regression models. In this work, we aim to evaluate this…

Schaadt, Gesa; Werwach, Annika; Obrig, Hellmuth; Friederici, Angela D.; Männel, Claudia – Child Development, 2023
Consonants and vowels differentially contribute to lexical acquisition. From 8 months on, infants' preferential reliance on consonants has been shown to predict their lexical outcome. Here, the predictive value of German-learning infants' (n = 58, 29 girls, 29 boys) trajectories of consonant and vowel perception, indicated by the…

Knowland, Victoria C. P.; Berens, Sam; Gaskell, M. Gareth; Walker, Sarah A.; Henderson, Lisa-Marie – Journal of Child Language, 2022
Children's vocabulary ability at school entry is highly variable and predictive of later language and literacy outcomes. Sleep is potentially useful in understanding and explaining that variability, with sleep patterns being predictive of global trajectories of language acquisition. Here, we looked to replicate and extend these findings. Data from…

Purpose: This study evaluates the extent to which automated indices of vocal development are stable and valid for predicting language in infants at increased familial likelihood for autism and/or language impairment and relatively lower likelihood infants. Method: A group of infants with autistic siblings (Sibs-autism; 20 infants) and a comparison…

Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White;…

Singh, Leher; Cheng, QiQi; Tan, Seok Hui; Tan, Agnes; Low, Yen Ling – Child Development, 2022
In this study, infant vocabulary development was tracked in a multilingual society (Singapore) within a socioeconomically diverse sample. The sample comprised 1316 infants from 17.4 to 27.7 months (669 females, 647 males; 88% Chinese race, 4% Malay, 4% Indian, and 0.004% mixed-race [4% declined to provide race information]). Children varied in…

Raneri, Daniele; Von Holzen, Katie; Newman, Rochelle; Bernstein Ratner, Nan – Journal of Child Language, 2020
Aims: Although IDS is typically described as slower than adult-directed speech (ADS), potential impacts of slower speech on language development have not been examined. We explored whether IDS speech rates in 42 mother-infant dyads at four time periods predicted children's language outcomes at two years. Method: We correlated IDS speech rate with…

Shapiro, Naomi Tachikawa; Hippe, Daniel S.; Ramírez, Naja Ferjan – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Fathers play a critical but underresearched role in their children's cognitive and linguistic development. Focusing on two-parent families with a mother and a father, the present longitudinal study explores the amount of paternal input infants hear during the first 2 years of life, how this input changes over time, and how it relates to…

Choi, Boin; Wei, Ran; Rowe, Meredith L. – Developmental Psychology, 2021
It is well established that deictic gestures, especially pointing, play an important role in children's language development. However, recent evidence suggests that other types of deictic gestures, specifically show and give gestures, emerge before pointing and are associated with later pointing. In the present study, we examined the development…

Purpose: Differences across language environments of prelingually deaf children who receive cochlear implants (CIs) may affect language acquisition; yet, whether mothers show individual differences in how they modify infant-directed (ID) compared with adult-directed (AD) speech has seldom been studied. This study assessed individual differences in…

Pronina, Mariia; Grofulovic, Jelena; Castillo, Eva; Prieto, Pilar; Igualada, Alfonso – Journal of Speech, Language, and Hearing Research, 2023
Purpose: Though the frequency of gesture use by infants has been related to the development of different language abilities in the initial stages of language acquisition, less is known about whether this frequency (or "gesture rate") continues to correlate with language measures in later stages of language acquisition, or whether the…

Lüke, Carina; Leinweber, Juliane; Ritterfeld, Ute – Journal of Child Language, 2019
Both walking abilities and pointing gestures in infants are associated with later language skills. Within this longitudinal study we investigate the relationship between walk onset and first observed index-finger points and their respectively predictive value for later language skills. We assume that pointing as a motor as well as a communicative…

Brookman, Ruth; Kalashnikova, Marina; Conti, Janet; Xu Rattanasone, Nan; Grant, Kerry-Ann; Demuth, Katherine; Burnham, Denis – Child Development, 2020
This longitudinal study investigated the effects of maternal emotional health concerns, on infants' home language environment, vocalization quantity, and expressive language skills. Mothers and their infants (at 6 and 12 months; 21 mothers with depression and or anxiety and 21 controls) provided day-long home-language recordings. Compared with…

Here we report, for the first time, a relationship between sensitivity to amplitude envelope rise time in infants and their later vocabulary development. Recent research in auditory neuroscience has revealed that amplitude envelope rise time plays a mechanistic role in speech encoding. Accordingly, individual differences in infant discrimination…

Choi, Boin; Shah, Priyanka; Rowe, Meredith L.; Nelson, Charles A.; Tager-Flusberg, Helen – Journal of Autism and Developmental Disorders, 2020
We investigated gesture production in infants at high and low risk for autism spectrum disorder (ASD) and caregiver responsiveness between 12 and 24 months of age and assessed the extent to which early gesture predicts later language and ASD outcomes. Participants included 55 high-risk infants, 21 of whom later met criteria for ASD, 34 low-risk…
