Olson, Janet; Masur, Elise – Language Learning and Development, 2020
The current study examined how mothers' production of four types of internal state words at multiple ages across the second year in a free play context was related to their infants' acquisition of those words. Twenty-nine mother-infant dyads were videotaped for 18 minutes during free play when infants were 13 and 17 months old. Mothers' total and…

Moore, Charlotte; Dailey, Shannon; Garrison, Hallie; Amatuni, Andrei; Bergelson, Elika – Developmental Psychology, 2019
Around their first birthdays, infants begin to point, walk, and talk. These abilities are appreciable both by researchers with strictly standardized criteria and caregivers with more relaxed notions of what each of these skills entails. Here, we compare the onsets of these skills and links among them across two data collection methods: observation…

Yamashiro, Amy; Vouloumanos, Athena – Developmental Psychology, 2019
Adult humans process communicative interactions by recognizing that information is being communicated through speech (linguistic ability) and simultaneously evaluating how to respond appropriately (social-pragmatic ability). These abilities may originate in infancy. Infants understand how speech communicates in social interactions, helping them…

Jackson-Maldonodo, Donna; Marchman, Virginia A.; Fernald, Lia C. H. – Applied Psycholinguistics, 2013
The Spanish-language MacArthur-Bates Communicative Development Inventories (S-CDIs) are well-established parent report tools for assessing the language development of Spanish-speaking children under 3 years. Here, we introduce the short-form versions of the S-CDIs (SFI and SFII), offered as alternatives to the long forms for screening purposes or…

Casasola, Marianella; Park, Youjeong – Child Development, 2013
Two experiments examined infants' ability to form a spatial category when habituated to few (only 2) or many (6) exemplars of a spatial relation. Sixty-four infants of 10 months and 64 infants of 14 months were habituated to dynamic events in which a toy was placed in a consistent spatial relation ("in" or "on") to a referent…

Simonsen, Hanne Gram; Kristoffersen, Kristian E.; Bleses, Dorthe; Wehberg, Sonja; Jørgensen, Rune N. – First Language, 2014
This article presents results from a large population-based study of early communicative development in Norwegian children using an adaptation of the MacArthur-Bates Communicative Development Inventories, comprising 6574 children between 8 and 36 months. Data were collected via the Internet. In accordance with similar studies from other languages,…

Fernald, Anne; Marchman, Virginia A.; Weisleder, Adriana – Developmental Science, 2013
This research revealed both similarities and striking differences in early language proficiency among infants from a broad range of advantaged and disadvantaged families. English-learning infants ("n" = 48) were followed longitudinally from 18 to 24 months, using real-time measures of spoken language processing. The first goal was to…

Colombo, John; Shaddy, D. Jill; Richman, W. Allen; Maikranz, Julie M.; Blaga, Otilia M. – Infancy, 2004
A longitudinal sample of 226 infants were tested monthly on habituation and novelty preference tasks, augmented with simultaneous heart rate recording from 3 to 9 months of age. Infants were then administered the Bayley Scales of Infant Development II (BSID) and MacArthur Communicative Development Inventory (MCDI) at 12, 18, and 24 months. Prior…
