Miranda Gómez Díaz; Laia Fibla; Rachel Ka-Ying Tsui; Krista Byers-Heinlein – Developmental Psychology, 2024
Sometime before their second birthday, many children have a period of rapid expressive vocabulary growth called the vocabulary spurt. Theories of the underlying mechanisms differ: Accumulator models emphasize the accumulation of experience with words over time to yield a spurtlike pattern, while cognitive models attribute the spurt to cognitive…

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…

Peer reviewed Peer reviewed

Edgar, Elizabeth V.; Todd, James Torrence; Bahrick, Lorraine E. – Developmental Psychology, 2022
Parent language input is a well-established predictor of child language development. Multisensory attention skills (MASks; intersensory matching, shifting and sustaining attention to audiovisual speech) are also known to be foundations for language development. However, due to a lack of appropriate measures, individual differences in these skills…

Children Show Selectively Increased Language Imitation after Experiencing Ostracism
Peer reviewed Peer reviewed

Hopkins, Zoe L.; Branigan, Holly P. – Developmental Psychology, 2020
When threatened with ostracism, children attempt to strengthen social relationships by engaging in affiliative behaviors such as imitation. We investigated whether an experience of ostracism influenced the extent to which children imitated a partner's language use. In two experiments, 7- to 12-year-old children either experienced ostracism or did…

Uljarevic, Mirko; Arnott, Bronia; Carrington, Sarah J.; Meins, Elizabeth; Fernyhough, Charles; McConachie, Helen; Le Couteur, Ann; Leekam, Susan R. – Developmental Psychology, 2017
A community sample of 192 parents reported on their children's restricted and repetitive behaviors (RRBs) at mean ages 15 months (N = 138), 26 months (N = 191), and 77 months (N = 125) using the Repetitive Behavior Questionnaire-2 (RBQ-2). Consistent with previous factor analytic research, 2 factors were found at each age: 1 comprising repetitive…

Despite the increasing prevalence of 3-generation family households (grandparent, parent, child), relatively little research has studied these households during early childhood. Using nationally representative data from the Early Childhood Longitudinal Study--Birth Cohort ("N" = ~6,550), this study investigated the associations between…
