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…

Bergelson, Elika; Casillas, Marisa; Soderstrom, Melanie; Seidl, Amanda; Warlaumont, Anne S.; Amatuni, Andrei – Developmental Science, 2019
A range of demographic variables influences how much speech young children hear. However, because studies have used vastly different sampling methods, quantitative comparison of interlocking demographic effects has been nearly impossible, across or within studies. We harnessed a unique collection of existing naturalistic, day-long recordings from…

Yu, Chen; Suanda, Sumarga H.; Smith, Linda B. – Developmental Science, 2019
Vocabulary differences early in development are highly predictive of later language learning as well as achievement in school. Early word learning emerges in the context of tightly coupled social interactions between the early learner and a mature partner. In the present study, we develop and apply a novel paradigm--dual head-mounted eye…

Fröhlich, Marlen; Wittig, Roman M.; Pika, Simone – Developmental Science, 2019
The onset of intentional communication in children's first year of life represents a major milestone in human cognitive development. Similarly, it is well established that our closest living relatives, the great apes, communicate with signals characterized by at least first-order intentionality. Despite the well-documented influence of…

Bakker, Merel; Torbeyns, Joke; Wijns, Nore; Verschaffel, Lieven; De Smedt, Bert – Developmental Science, 2019
Numerical competencies acquired in preschool are foundational and predictive for children's later mathematical development. It remains to be determined whether there are gender differences in these early numerical competencies which could explain the often-reported gender differences in later mathematics and STEM-related abilities. Using a…

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…

Broadbent, Hannah J.; Osborne, Tamsin; Mareschal, Denis; Kirkham, Natasha Z. – Developmental Science, 2019
Multisensory tools are commonly employed within educational settings (e.g. Carter & Stephenson, 2012), and there is a growing body of literature advocating the benefits of presenting children with multisensory information over unisensory cues for learning (Baker & Jordan, 2015; Jordan & Baker, 2011). This is even the case when the…

Murray, Aja Louise; Booth, Tom; Eisner, Manuel; Auyeung, Bonnie; Murray, George; Ribeaud, Denis – Developmental Science, 2019
Previous studies have hinted at sex differences in developmental trajectories in ADHD symptoms; however, little is known about the nature or cause of these differences and their implications for clinical practice. We used growth mixture modelling in a community-ascertained cohort of n = 1,571 participants to study sex differences in ADHD symptom…

Reid, Gwendolynne – Written Communication, 2019
Drawing on a text-based ethnography of digital writing in a biology laboratory, this article examines the text trajectory of a scientific manuscript and a scientific team's related writing for public audiences, including for citizen scientists. Using data drawn from texts, observations, interviews, and related artifacts, the author examines how…

Bray, Nancy – Written Communication, 2019
The Internet has helped to change who writes about science in the news, how news is written, and how it is taken up by different audiences. However, few studies have examined how these changes have impacted the uptake of scientific claims in online news writing. This case study explores how online news genres take up knowledge claims from a…

Hanauer, David I.; Sheridan, Cheryl L.; Englander, Karen – Written Communication, 2019
This study investigates the added burden Mexican and Taiwanese non-native English speaker (NNES) researchers perceive when writing research articles in English as a second language (L2) compared with their experience of first language (L1) science writing. 148 Mexican and 236 Taiwanese researchers completed an established survey of science writing…

Gottfried, Michael A. – Urban Education, 2019
Although educational policy makers uphold that chronic absenteeism (missing 10% or more of the school year) is damaging to students' schooling outcomes, there is little empirical research to match. This study considers the role of spillover effects of chronic absenteeism on classmates' achievement. It does so by utilizing a large-scale…

Mac Iver, Martha Abele; Mac Iver, Douglas J. – Urban Education, 2019
This article reports findings from a quasi-experimental study of the impact of a summer robotics program for urban middle-grade students. The study focuses on student engagement, measured by school attendance rate the year following the program. Program students, who were nearly all low-income minority students, were matched to comparison students…

Posmontier, Bobbie; Bina, Rena; Glasser, Saralee; Cinamon, Tali; Styr, Benedict; Sammarco, Therese – Research on Social Work Practice, 2019
Purpose: To determine feasibility and acceptability of incorporating IPT for postpartum depression (PPD) into Israeli social work practice. Method: Women who were 4-24 weeks postpartum with PPD, at least 18 years old, had telephone access, and had a score of 10-18 on the Edinburgh Postnatal Depression Scale (EPDS) were eligible to participate in…

van Rensburg, Angelique C.; Theron, Linda C.; Ungar, Michael – Research on Social Work Practice, 2019
Purpose: The factor structure of the Child and Youth Resilience Measure (CYRM-28) was originally established using a Canadian sample. This factor structure was not confirmed in a study with New Zealand youth. Given such variability, the current study investigated the factor structure of the CYRM-28 in a sample of Sesotho-speaking South African…
