Grossheinrich, Nicola; Schulte-Körne, Gerd; Marschik, Peter B; Kademann, Stefanie; von Suchodoletz, Waldemar; Sachse, Steffi – Developmental Science, 2019
Background: Early intervention for children identified as late talkers (LTs) at the age of 24 months is still a controversial issue in research and clinical routine. Previous studies have shown inconsistent results regarding predictors of early lexical deficits on school-age outcomes of late-talking toddlers. Methods: In a five-wave follow-up…

Quémart, Pauline; Gonnerman, Laura M.; Downing, Jennifer; Deacon, S. Hélène – Developmental Science, 2018
The way children organize words in their memory has intrigued many researchers in the past 20 years. Given the large number of morphologically complex words in many languages, the influence of morphemes on this organization is being increasingly examined. The aim of this study was to understand how morphemic information influences English-speaking…

Coch, Donna – Developmental Science, 2015
While behavioral and educational data characterize a fourth grade shift in reading development, neuroscience evidence is relatively lacking. We used the N400 component of the event-related potential waveform to investigate the development of single word processing across the upper elementary years, in comparison to adult readers. We presented…

Lyons, Ian M.; Price, Gavin R.; Vaessen, Anniek; Blomert, Leo; Ansari, Daniel – Developmental Science, 2014
Math relies on mastery and integration of a wide range of simpler numerical processes and concepts. Recent work has identified several numerical competencies that predict variation in math ability. We examined the unique relations between eight basic numerical skills and early arithmetic ability in a large sample (N = 1391) of children across…

Prado, Jérôme; Mutreja, Rachna; Booth, James R. – Developmental Science, 2014
Mastering single-digit arithmetic during school years is commonly thought to depend upon an increasing reliance on verbally memorized facts. An alternative model, however, posits that fluency in single-digit arithmetic might also be achieved via the increasing use of efficient calculation procedures. To test between these hypotheses, we used a…

Rouder, Jeffrey N.; Geary, David C. – Developmental Science, 2014
Learning of the mathematical number line has been hypothesized to be dependent on an inherent sense of approximate quantity. Children's number line placements are predicted to conform to the underlying properties of this system; specifically, placements are exaggerated for small numerals and compressed for larger ones. Alternative hypotheses…

Perea, Manuel; Mallouh, Reem Abu; Carreiras, Manuel – Developmental Science, 2013
A commonly shared assumption in the field of visual-word recognition is that retinotopic representations are rapidly converted into abstract representations. Here we examine the role of visual form vs. abstract representations during the early stages of word processing--as measured by masked priming--in young children (3rd and 6th Graders) and…

Raver, C. Cybele; McCoy, Dana Charles; Lowenstein, Amy E.; Pess, Rachel – Developmental Science, 2013
The present longitudinal study tested the roles of early childhood executive control (EC) as well as exposure to poverty-related adversity at family and school levels as key predictors of low-income children's EC in elementary school ("n" = 391). Findings suggest that children's EC difficulties in preschool and lower family income from…

Brissiaud, Remi; Sander, Emmanuel – Developmental Science, 2010
Before instruction, children solve many arithmetic word problems with informal strategies based on the situation described in the problem. A Situation Strategy First framework is introduced that posits that initial representation of the problem activates a situation-based strategy even after instruction: only when it is not efficient for providing…
