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…

Plate, Samantha; Yankowitz, Lisa; Resorla, Leslie; Swanson, Meghan R.; Meera, Shoba Sreenath; Estes, Annette; Marrus, Natasha; Cola, Meredith; Petrulla, Victoria; Faggen, Aubrey; Pandey, Juhi; Paterson, Sarah; Pruett, John R., Jr.; Hazlett, Heather; Dager, Stephen; St. John, Tanya; Botteron, Kelly; Zwaigenbaum, Lonnie; Piven, Joseph; Schultz, Robert T.; Parish-Morris, Julia – Child Development, 2022
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;…

Morin-Lessard, Elizabeth; Hentges, Rochelle F.; Tough, Suzanne C.; Graham, Susan A. – Child Development, 2021
Using data from the All Our Families study, a longitudinal study of 1992 mother-child dyads in Canada (47.7% female; 81.9% White), we examined the developmental pathways between infant gestures and symbolic actions and communicative skills at age 5. Communicative gestures at age 12 months (e.g., pointing, nodding head "yes"), obtained…

Chen, Yun-Ju; Sideris, John; Watson, Linda R.; Crais, Elizabeth R.; Baranek, Grace T. – Child Development, 2022
This prospective study examined the latent growth trajectories of sensory patterns among a North Carolina birth cohort (N = 1517; 49% boys, 87% White) across infancy (6-19 months), preschool (3-4 years), and school years (6-7 years). Change rates of sensory hyper- and hyporesponsiveness better differentiated children with an autism diagnosis or…

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…

Devine, Rory T.; Ribner, Andrew; Hughes, Claire – Child Development, 2019
This study of 195 (108 boys) children seen twice during infancy (Time 1: 4.12 months; Time 2: 14.42 months) aimed to investigate the associations between and infant predictors of executive function (EF) at 14 months. Infants showed high levels of compliance with the EF tasks at 14 months. There was little evidence of cohesion among EF tasks but…

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…

Lucca, Kelsey; Wilbourn, Makeba Parramore – Child Development, 2018
Infants' pointing gestures are a critical predictor of early vocabulary size. However, it remains unknown precisely how pointing relates to word learning. The current study addressed this question in a sample of 108 infants, testing one mechanism by which infants' pointing may influence their learning. In Study 1, 18-month-olds, but not…

McGillion, Michelle; Herbert, Jane S.; Pine, Julian; Vihman, Marilyn; dePaolis, Rory; Keren-Portnoy, Tamar; Matthews, Danielle – Child Development, 2017
A child's first words mark the emergence of a uniquely human ability. Theories of the developmental steps that pave the way for word production have proposed that either vocal or gestural precursors are key. These accounts were tested by assessing the developmental synchrony in the onset of babbling, pointing, and word production for 46 infants…

Swingley, Daniel; Humphrey, Colman – Child Development, 2018
To evaluate which features of spoken language aid infant word learning, a corpus of infant-directed speech (M. R. Brent & J. M. Siskind, 2001) was characterized on several linguistic dimensions and statistically related to the infants' vocabulary outcomes word by word. Comprehension (at 12 and 15 months) and production (15 months) were…

Salomo, Dorothe; Liszkowski, Ulf – Child Development, 2013
Daily activities of forty-eight 8- to 15-month-olds and their interlocutors were observed to test for the presence and frequency of triadic joint actions and deictic gestures across three different cultures: Yucatec-Mayans (Mexico), Dutch (Netherlands), and Shanghai-Chinese (China). The amount of joint action and deictic gestures to which infants…

Fair, Joseph; Flom, Ross; Jones, Jacob; Martin, Justin – Child Development, 2012
Six-month-olds reliably discriminate different monkey and human faces whereas 9-month-olds only discriminate different human faces. It is often falsely assumed that perceptual narrowing reflects a permanent change in perceptual abilities. In 3 experiments, ninety-six 12-month-olds' discrimination of unfamiliar monkey faces was examined. Following…

Mannering, Anne M.; Harold, Gordon T.; Leve, Leslie D.; Shelton, Katherine H.; Shaw, Daniel S.; Conger, Rand D.; Neiderhiser, Jenae M.; Scaramella, Laura V.; Reiss, David – Child Development, 2011
This study examined the longitudinal association between marital instability and child sleep problems at ages 9 and 18 months in 357 families with a genetically unrelated infant adopted at birth. This design eliminates shared genes as an explanation for similarities between parent and child. Structural equation modeling indicated that T1 marital…

Bernier, Annie; Carlson, Stephanie M.; Whipple, Natasha – Child Development, 2010
In keeping with proposals emphasizing the role of early experience in infant brain development, this study investigated the prospective links between quality of parent-infant interactions and subsequent child executive functioning (EF), including working memory, impulse control, and set shifting. Maternal sensitivity, mind-mindedness and autonomy…

Propper, Cathi; Moore, Ginger A.; Mills-Koonce, W. Roger; Halpern, Carolyn Tucker; Hill-Soderlund, Ashley L.; Calkins, Susan D.; Carbone, Mary Anna; Cox, Martha – Child Development, 2008
This study investigated dopamine receptor genes ("DRD2" and "DRD4") and maternal sensitivity as predictors of infant respiratory sinus arrhythmia (RSA) and RSA reactivity, purported indices of vagal tone and vagal regulation, in a challenge task at 3, 6, and 12 months in 173 infant-mother dyads. Hierarchical linear modeling (HLM) revealed that at…
