Morton, Hannah E.; Gillis, Jennifer M.; Mattson, Richard E.; Romanczyk, Raymond G. – Autism: The International Journal of Research and Practice, 2019
Children with autism spectrum disorder experience bullying more frequently than their typical peers. Inconsistent definitions for and imprecise measurement of bullying in the literature impede a better understanding of this difference, and multiple types of bullying topographies create additional dimensions for analysis. In this study,…

Graham, Steve; Hebert, Michael; Fishman, Evan; Ray, Amber B.; Rouse, Amy Gillespie – Journal of Learning Disabilities, 2020
In this meta-analysis, we examined whether children classified with specific language impairment (SLI) experience difficulties with writing. We included studies comparing children with SLI to (a) typically developing peers matched on age (k = 39 studies) and (b) typically developing younger peers with similar language capabilities (k = six…

Christensen, Rikke Vang – Journal of Speech, Language, and Hearing Research, 2019
Purpose: The aim of the study was to explore the potential of performance on a Danish sentence repetition (SR) task--including specific morphological and syntactic properties--to identify difficulties in children with developmental language disorder (DLD) relative to typically developing (TD) children. Furthermore, the potential of the task as a…

McConnell-Nzunga, J.; Naylor, P. J.; Macdonald, H.; Rhodes, R. E.; Hofer, S. M.; McKay, H. – Measurement in Physical Education and Exercise Science, 2018
Body mass index is a common proxy for proportion of body fat. However, body mass index may not classify youth similarly across ages and ethnicities. We used sex- and ethnic-specific receiver operating characteristic curves to determine how obesity classifications compared between body mass index and dual energy x-ray absorptiometry-based body fat…

McMurray, Bob; Danelz, Ani; Rigler, Hannah; Seedorff, Michael – Developmental Psychology, 2018
The development of the ability to categorize speech sounds is often viewed as occurring primarily during infancy via perceptual learning mechanisms. However, a number of studies suggest that even after infancy, children's categories become more categorical and well defined through about age 12. We investigated the cognitive changes that may be…

National Center on Deaf-Blindness, 2022
The annual National Deaf-Blind Child Count is the world's first and longest running count of children who are deaf-blind. Begun in 1986 on behalf of the U.S. Department of Education, it represents a collaborative effort between the National Center on Deaf-Blindness (NCDB) and state deaf-blind projects throughout the country, including those in the…

Finn, Kevin J.; Saint-Maurice, Pedro F.; Karsai, István; Ihász, Ferenc; Csányi, Tamás – Research Quarterly for Exercise and Sport, 2015
Purpose: The purpose of this study was to test the convergent validity of Omron 306 using Biospace InBody 720. Method: A total of 267 participants (145 boys; aged 10.4-17.9 years) completed testing during a single session. Each measure provided percent body fat (%BF), while the InBody 720 included fat-free mass (FFM). The validity was examined…

In recently published studies on cyberbullying, students are frequently categorized into distinct (cyber)bully and (cyber)victim clusters based on theoretical assumptions and arbitrary cut-off scores adapted from traditional bullying research. The present study identified involvement classes empirically using latent class analysis (LCA), to…

Lukács, Ágnes; Kemény, Ferenc – Cognitive Science, 2015
The acquisition of complex motor, cognitive, and social skills, like playing a musical instrument or mastering sports or a language, is generally associated with implicit skill learning (SL). Although it is a general view that SL is most effective in childhood, and such skills are best acquired if learning starts early, this idea has rarely been…

Michalcáková, Radka; Lacinová, Lenka; Kyjonková, Hana; Bouša, Ondrej; Jelínek, Martin – Journal of Early Adolescence, 2013
The present study investigates developmental patterns of fear in adolescence. It is based on longitudinal data collected as a part of the European Longitudinal Study of Pregnancy and Childhood (ELSPAC) project. A total of 186 Czech adolescents (43% girls) were assessed repeatedly at the age of 11, 13, and 15 years. The free-response method was…

Juttner, Martin; Wakui, Elley; Petters, Dean; Kaur, Surinder; Davidoff, Jules – Developmental Psychology, 2013
Three experiments assessed the development of children's part and configural (part-relational) processing in object recognition during adolescence. In total, 312 school children aged 7-16 years and 80 adults were tested in 3-alternative forced choice (3-AFC) tasks. They judged the correct appearance of upright and inverted presented familiar…

Strauss, Mark S.; Newell, Lisa C.; Best, Catherine A.; Hannigen, Sarah F.; Gastgeb, Holly Zajac; Giovannelli, Joyce L. – Journal of Autism and Developmental Disorders, 2012
While much research has examined the development of facial recognition abilities, less is known about the ability of individuals with and without autism to categorize facial gender. The current study tested gender categorization abilities in high-functioning children (5-7 and 8-12 years), adolescents (13-17 years), and adults (18-53 years) with…

Jansen, Brenda R. J.; van Duijvenvoorde, Anna C. K.; Huizenga, Hilde M. – Journal of Experimental Child Psychology, 2012
Decisions can be made by applying a variety of decision-making rules--sequential rules in which decisions are based on a sequential evaluation of choice dimensions and the integrative normative rule in which decisions are based on an integration of choice dimensions. In this study, we investigated the developmental trajectory of such…
