Christine Michel; Daniel Matthes; Stefanie Hoehl – Child Development, 2024
This study investigates infants' neural and behavioral responses to maternal ostensive signals during naturalistic mother-infant interactions and their effects on object encoding. Mothers familiarized their 9- to 10-month-olds (N = 35, 17 females, mainly White, data collection: 2018-2019) with objects with or without mutual gaze, infant-directed…

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;…

Herzberg, Orit; Fletcher, Katelyn K.; Schatz, Jacob L.; Adolph, Karen E.; Tamis-LeMonda, Catherine S. – Child Development, 2022
Object play yields enormous benefits for infant development. However, little is known about natural play at home where most object interactions occur. We conducted frame-by-frame video analyses of spontaneous activity in two 2-h home visits with 13-month-old crawling infants and 13-, 18-, and 23-month-old walking infants (N = 40; 21 boys; 75%…

Zwaigenbaum, Lonnie; Bryson, Susan E.; Brian, Jessica; Smith, Isabel M.; Sacrey, Lori; Armstrong, Vickie; Roberts, Wendy; Szatmari, Peter; Garon, Nancy; Vaillancourt, Tracy; Roncadin, Caroline – Child Development, 2021
The objectives were to characterize behavioral signs of autism spectrum disorder (ASD) in younger siblings of diagnosed children (high-risk; HR) and examine classification features of the Autism Observation Scale for Infants (AOSI). Participants (501 HR and 180 low-risk [LR]) were assessed between 6 and 18 months using the AOSI and at age 3 for…

Gredebäck, Gustaf; Astor, Kim; Fawcett, Christine – Child Development, 2018
The theory of natural pedagogy stipulates that infants follow gaze because they are sensitive to the communicative intent of others. According to this theory, gaze following should be present if, and only if, accompanied by at least one of a set of specific ostensive cues. The current article demonstrates gaze following in a range of contexts,…

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…

Stroud, Laura R.; Papandonatos, George D.; Salisbury, Amy L.; Phipps, Maureen G.; Huestis, Marilyn A.; Niaura, Raymond; Padbury, James F.; Marsit, Carmen J.; Lester, Barry M. – Child Development, 2016
Epigenetic regulation of the placental glucocorticoid receptor gene ("NR3C1") was investigated as a mechanism underlying links between maternal smoking during pregnancy (MSDP) and infant neurobehavior in 45 mother-infant pairs (49% MSDP-exposed; 52% minorities; ages 18-35). The Neonatal Intensive Care Unit (NICU) Network Neurobehavioral…

Forssman, Linda; Wass, Sam V. – Child Development, 2018
This study investigated transfer effects of gaze-interactive attention training to more complex social and cognitive skills in infancy. Seventy 9-month-olds were assigned to a training group (n = 35) or an active control group (n = 35). Before, after, and at 6-week follow-up both groups completed an assessment battery assessing transfer to…

Bergelson, Elika; Swingley, Daniel – Child Development, 2018
To understand spoken words, listeners must appropriately interpret co-occurring talker characteristics and speech sound content. This ability was tested in 6- to 14-months-olds by measuring their looking to named food and body part images. In the "new talker" condition (n = 90), pictures were named by an unfamiliar voice; in the…

Pickron, Charisse B.; Iyer, Arjun; Fava, Eswen; Scott, Lisa S. – Child Development, 2018
This study examined differences in visual attention as a function of label learning from 6 to 9 months of age. Before and after 3 months of parent-directed storybook training with computer-generated novel objects, event-related potentials and visual fixations were recorded while infants viewed trained and untrained images (n = 23). Relative to a…
