Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

Mitsven, Samantha G.; Perry, Lynn K.; Tao, Yudong; Elbaum, Batya E.; Johnson, Neil F.; Messinger, Daniel S. – Developmental Science, 2022
Over half of US children are enrolled in preschools, where the quantity and quality of language input from teachers are likely to affect children's language development. Leveraging repeated objective measurements, we examined the rate per minute and phonemic diversity of child and teacher speech-related vocalizations in preschool classrooms and…

Griffiths, Sarah; Kievit, Rogier A.; Norbury, Courtenay – Developmental Science, 2022
Mutualism is a developmental theory that posits positive reciprocal relationships between distinct cognitive abilities during development. It predicts that abilities such as language and reasoning will influence each other's rates of growth. This may explain why children with Language Disorders also tend to have lower than average non-verbal…

Smith, Elizabeth G.; Condy, Emma; Anderson, Afrouz; Thurm, Audrey; Manwaring, Stacy S.; Swineford, Lauren; Gandjbakhche, Amir; Redcay, Elizabeth – Developmental Science, 2020
The toddler and preschool years are a time of significant development in both expressive and receptive communication abilities. However, little is known about the neurobiological underpinnings of language development during this period, likely due to difficulties acquiring functional neuroimaging data. Functional near-infrared spectroscopy (fNIRS)…

Ece Demir-Lira, Ö.; Applebaum, Lauren R.; Goldin-Meadow, Susan; Levine, Susan C. – Developmental Science, 2019
It is widely believed that reading to preschool children promotes their language and literacy skills. Yet, whether early parent-child book reading is an index of generally rich linguistic input or a unique predictor of later outcomes remains unclear. To address this question, we asked whether naturally occurring parent-child book reading…

Mahr, Tristan; Edwards, Jan – Developmental Science, 2018
Children learn words by listening to caregivers, and the quantity and quality of early language input predict later language development. Recent research suggests that word recognition efficiency may influence the relationship between input and vocabulary growth. We asked whether language input and lexical processing at 28-39 months predicted…
