Hurst, Michelle A.; Cordes, Sara – Developmental Science, 2019
Across two experiments, we investigated how verbal labels impact the way young children attend to proportional information, well before the introduction of formal fraction education. Five- to seven-year-old children were introduced to equivalent non-symbolic proportions labeled in one of three ways: (a) a single, categorical label for multiple…

Fló, Ana; Brusini, Perrine; Macagno, Francesco; Nespor, Marina; Mehler, Jacques; Ferry, Alissa L. – Developmental Science, 2019
Before infants can learn words, they must identify those words in continuous speech. Yet, the speech signal lacks obvious boundary markers, which poses a potential problem for language acquisition (Swingley, "Philos Trans R Soc Lond. Series B, Biol Sci" 364(1536), 3617-3632, 2009). By the middle of the first year, infants seem to have…

Comishen, Kyle J.; Bialystok, Ellen; Adler, Scott A. – Developmental Science, 2019
Bilingualism has been observed to influence cognitive processing across the lifespan but whether bilingual environments have an effect on selective attention and attention strategies in infancy remains an unresolved question. In Study 1, infants exposed to monolingual or bilingual environments participated in an eye-tracking cueing task in which…

Wolf, Sharon; McCoy, Dana Charles – Developmental Science, 2019
The majority of evidence on the interplay between academic and non-academic skills comes from high-income countries. The aim of this study was to examine the bidirectional associations between Ghanaian children's executive function, social-emotional, literacy, and numeracy skills longitudinally. Children (N = 3,862; M age = 5.2 years at time 1)…

Hoareau, Mélanie; Yeung, H. Henny; Nazzi, Thierry – Developmental Science, 2019
Individual variability in infant's language processing is partly explained by environmental factors, like the quantity of parental speech input, as well as by infant-specific factors, like speech production. Here, we explore how these factors affect infant word segmentation. We used an artificial language to ensure that only statistical…

Grzyb, Beata J.; Nagai, Yukie; Asada, Minoru; Cattani, Allegra; Floccia, Caroline; Cangelosi, Angelo – Developmental Science, 2019
Young children sometimes attempt an action on an object, which is inappropriate because of the object size--they make scale errors. Existing theories suggest that scale errors may result from immaturities in children's action planning system, which might be overpowered by increased complexity of object representations or developing teleofunctional…

Fecher, Natalie; Johnson, Elizabeth K. – Developmental Science, 2019
Bilingual and monolingual infants differ in how they process linguistic aspects of the speech signal. But do they also differ in how they process non-linguistic aspects of speech, such as who is talking? Here, we addressed this question by testing Canadian monolingual and bilingual 9-month-olds on their ability to learn to identify native…

Hernik, Mikolaj; Broesch, Tanya – Developmental Science, 2019
Gaze is considered a crucial component of early communication between an infant and her caregiver. When communicatively addressed, infants respond aptly to others' gaze by following its direction. However, experience with face-to-face contact varies across cultures, begging the question whether infants' competencies in receiving others'…

Zhang, Felicia; Jaffe-Dax, Sagi; Wilson, Robert C.; Emberson, Lauren L. – Developmental Science, 2019
Adults use both bottom-up sensory inputs and top-down signals to generate predictions about future sensory inputs. Infants have also been shown to make predictions with simple stimuli and recent work has suggested top-down processing is available early in infancy. However, it is unknown whether this indicates that top-down prediction is an ability…

Nicoladis, Elena; Marentette, Paula; Pika, Simone – Developmental Science, 2019
Monolingual English-speaking preschool children tend to process number gestures as unanalyzed wholes rather than use the one-to-one (finger-to-quantity) correspondence. By school age, however, children can use the one-to-one correspondence. The purpose of the present studies was to test whether children learn one-to-one correspondence through…

Lin, Dan; Sun, Huilin; McBride, Catherine – Developmental Science, 2019
In this longitudinal study, we assessed 88 Hong Kong Chinese typically developing kindergarteners' Chinese character reading accuracy four times with 6-month intervals over 1.5 years with the first testing point in the fall of the second year of kindergarten (K2), during which morphological awareness, phonological awareness, orthographic…

Wolf, Sharon; Aber, J. Lawrence; Behrman, Jere R.; Peele, Morgan – Developmental Science, 2019
Preschool programs have expanded rapidly in low- and middle-income countries, but there are widespread concerns about whether they are of sufficient quality to promote children's learning and development. We conducted a large school-randomized control trial ('Quality Preschool for Ghana' -- QP4G) of a one-year teacher training and coaching…

Knauer, Heather A.; Kariger, Patricia; Jakiela, Pamela; Ozier, Owen; Fernald, Lia C. H. – Developmental Science, 2019
In many low- and middle-income countries, young children learn a mother tongue or indigenous language at home before entering the formal education system where they will need to understand and speak a country's official language(s). Thus, assessments of children before school age, conducted in a nation's official language, may not fully reflect a…

Lervåg, Arne; Dolean, Dacian; Tincas, Ioana; Melby-Lervåg, Monica – Developmental Science, 2019
Abstract Few studies have examined how socioeconomic status (SES) affects two essential parts of human development, namely vocabulary and reading comprehension, in children facing severe poverty. The Roma population is the largest minority group in Europe, the majority of whom live in severe poverty. This study compared the development of 322 Roma…

Starkey, Leighann; Aber, J. Lawrence; Crossman, Angela – Developmental Science, 2019
Exposure to community violence is thought to create risk for the social and emotional development of children, including those children living in low-income, conflict-affected countries. In the absence of other types of community resources, schools may be one of the few community resources that can help buffer children from the negative effects of…
