Machlin, Laura; McLaughlin, Katie A.; Sheridan, Margaret A. – Developmental Science, 2020
Low socioeconomic status (SES) is associated with greater risk for symptoms of attention-deficit/hyperactivity disorder (ADHD). One mechanism through which SES may confer risk for ADHD is by influencing brain structure. Alterations to cortical thickness, surface area and subcortical volume have been associated with low SES and with the presence of…

Hahn, Michael; Joechner, Ann-Kathrin; Roell, Judith; Schabus, Manuel; Heib, Dominik P. J.; Gruber, Georg; Peigneux, Philippe; Hoedlmoser, Kerstin – Developmental Science, 2019
Sleep spindles are related to sleep-dependent memory consolidation and general cognitive abilities. However, they undergo drastic maturational changes during adolescence. Here we used a longitudinal approach (across 7 years) to explore whether developmental changes in sleep spindle density can explain individual differences in sleep-dependent…

Snowling, Margaret J.; Lervåg, Arne; Nash, Hannah M.; Hulme, Charles – Developmental Science, 2019
Speech perception deficits are commonly reported in dyslexia but longitudinal evidence that poor speech perception compromises learning to read is scant. We assessed the hypothesis that phonological skills, specifically phoneme awareness and RAN, mediate the relationship between speech perception and reading. We assessed longitudinal predictive…

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…

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…

Obradovic, Jelena; Finch, Jenna E.; Portilla, Ximena A.; Rasheed, Muneera A.; Tirado-Strayer, Nicole; Yousafzai, Aisha K. – Developmental Science, 2019
This study extends the methodological and theoretical understanding of executive functions (EFs) in preschoolers from low- and middle-income countries (LMIC). First, the authors describe a rigorous process of adapting and evaluating six EF tasks to produce a culturally and developmentally appropriate measure of emerging EFs in a large sample of…

Rollins, Leslie; Riggins, Tracy – Developmental Science, 2018
The ability to mentally re-experience past events improves significantly from childhood to young adulthood; however, the mechanisms underlying this ability remain poorly understood, partially because different tasks are used across the lifespan. This study was designed to address this gap by assessing the development of event-related potential…

Jones, Pete R.; Dekker, Tessa M. – Developmental Science, 2018
The mature visual system condenses complex scenes into simple summary statistics (e.g., average size, location, orientation, etc.). However, children, often perform poorly on perceptual averaging tasks. Children's difficulties are typically thought to represent the suboptimal implementation of an adult-like strategy. This paper examines another…

Perry, Lynn K.; Perlman, Marcus; Winter, Bodo; Massaro, Dominic W.; Lupyan, Gary – Developmental Science, 2018
Iconicity--the correspondence between form and meaning--may help young children learn to use new words. Early-learned words are higher in iconicity than later learned words. However, it remains unclear what role iconicity may play in actual language use. Here, we ask whether iconicity relates not just to the age at which words are acquired, but…

Meltzoff, Andrew N.; Murray, Lynne; Simpson, Elizabeth; Heimann, Mikael; Nagy, Emese; Nadel, Jacqueline; Pedersen, Eric J.; Brooks, Rechele; Messinger, Daniel S.; De Pascalis, Leonardo; Subiaul, Francys; Paukner, Annika; Ferrari, Pier F. – Developmental Science, 2018
The meaning, mechanism, and function of imitation in early infancy have been actively discussed since Meltzoff and Moore's (1977) report of facial and manual imitation by human neonates. Oostenbroek et al. (2016) claim to challenge the existence of early imitation and to counter all interpretations so far offered. Such claims, if true, would have…

Constantinescu, Mihaela; Moore, David S.; Johnson, Scott P.; Hines, Melissa – Developmental Science, 2018
Some cognitive abilities exhibit reliable gender differences, with females outperforming males in specific aspects of verbal ability, and males showing an advantage on certain spatial tasks. Among these cognitive gender differences, differences in mental rotation are the most robust, and appear to be present even in infants. A large body of animal…

Fischer, Ursula; Suggate, Sebastian P.; Schmirl, Judith; Stoeger, Heidrun – Developmental Science, 2018
Finger counting is widely considered an important step in children's early mathematical development. Presumably, children's ability to move their fingers during early counting experiences to aid number representation depends in part on their early fine motor skills (FMS). Specifically, FMS should link to children's procedural counting skills…

Schneider, Michael; Beeres, Kassandra; Coban, Leyla; Merz, Simon; Schmidt, S. Susan; Stricker, Johannes; De Smedt, Bert – Developmental Science, 2017
Many studies have investigated the association between numerical magnitude processing skills, as assessed by the numerical magnitude comparison task, and broader mathematical competence, e.g. counting, arithmetic, or algebra. Most correlations were positive but varied considerably in their strengths. It remains unclear whether and to what extent…

Lourenco, Stella F.; Bonny, Justin W. – Developmental Science, 2017
A growing body of evidence suggests that non-symbolic representations of number, which humans share with nonhuman animals, are functionally related to uniquely human mathematical thought. Other research suggesting that numerical and non-numerical magnitudes not only share analog format but also form part of a general magnitude system raises…

Travers, Brittany G.; Bigler, Erin D.; Duffield, Tyler C.; Prigge, Molly D. B.; Froehlich, Alyson L.; Lange, Nicholas; Alexander, Andrew L.; Lainhart, Janet E. – Developmental Science, 2017
Many individuals with autism spectrum disorder (ASD) exhibit motor difficulties, but it is unknown whether manual motor skills improve, plateau, or decline in ASD in the transition from childhood into adulthood. Atypical development of manual motor skills could impact the ability to learn and perform daily activities across the life span. This…
