Anjie Cao; Molly Lewis; Sho Tsuji; Christina Bergmann; Alejandrina Cristia; Michael C. Frank – Developmental Science, 2025
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…

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;…

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…

Infants' Intentionally Communicative Vocalizations Elicit Responses from Caregivers and Are the Best Predictors of the Transition to Language: A Longitudinal Investigation of Infants' Vocalizations, Gestures and Word Production
Peer reviewed Peer reviewed

Donnellan, Ed; Bannard, Colin; McGillion, Michelle L.; Slocombe, Katie E.; Matthews, Danielle – Developmental Science, 2020
What aspects of infants' prelinguistic communication are most valuable for learning to speak, and why? We test whether early vocalizations and gestures drive the transition to word use because, in addition to indicating motoric readiness, they (a) are early instances of intentional communication and (b) elicit verbal responses from caregivers. In…

Davison, Linnea; Warwick, Haven; Campbell, Kaitlyn; Gartstein, Maria A. – Journal of Education and e-Learning Research, 2019
An extensive literature links language problems with behavioral difficulties and academic underachievement. Although less extensive, emerging literature suggests that temperament, Positive Affectivity (PA) in particular, contributes to language development. Thus, the present study was focused on PA related temperament dimensions in infancy as…
