Purpose: Production of complex syntax is a hallmark of later language development; however, most of the research examining age-related changes has focused on adolescents or analyzed narrative language samples. Research documenting age-related changes in the production of complex syntax in elementary school-aged children in conversational language…

The purpose of this systematic review was to examine the influence of relative age effect (RAE) on motor competences (MC) and physical fitness (PF) of preschool children. The search was conducted through three different databases: Web of Science, Scopus and EBSCO up to 11 August 2023. This study was conducted and reported according to the PRISMA…

Existing theories and frameworks generally have regarded creativity as inhering in a person, a task, a situation, or a combination of 2 of these 3 elements. After reviewing these approaches, and frameworks that are based on the interaction of more than 2 components, we propose a Person × Task × Situation synergistic paradigm, according to which…

The mental health and well-being of children and adolescents are critical public health concerns globally. This cross-sectional study analysed nationally representative data from the combined 2016-2022 National Survey of Children's Health (n = 239,534) to produce estimates of parent-reported diagnoses of children's anxiety, depression and…

The current study examines change and stability of cognitive skills across life stages and delves into the factors contributing to changes in cognitive skills. Specifically, we examine the associations between cognitive skills and individual characteristics and contextual factors in a large sample of German adults aged 16-65 years (N = 2,430;…

In a seminal study, Cameron-Faulkner et al. made two important observations about utterance-level constructions in English child-directed speech (CDS). First, they observed that canonical in/transitive sentences are surprisingly infrequent in child-direct speech (given that SVO word order is often thought to play a key role in the acquisition of…

Introduction: The purpose of this study was to investigate factors associated with having proficient braille skill, with a specific interest in employment status. Method: Survey data were collected in 2021 and 2022 from 449 employed and unemployed people with low vision and people who are blind, all of whom were legally blind. Proficient braille…

Purpose: "Dynamic pitch," which is defined as the variation in fundamental frequency in speech, is one of the acoustic cues that affect speech recognition in noise. Built on the evidence that a symmetrical manipulation of dynamic pitch led to poorer speech recognition, the present study examined the effect of an asymmetrical manipulation…

Background: Sedentary behaviour (SB) among adults with Down syndrome (DS) may differ based on personal or environmental factors. Objective: Investigate differences in SB levels and patterns of adults with DS based on sex, age, and residence-type across weekdays and weekends. Methods: Thirty-four adults with DS (15 men; 37 ± 12 years) underwent…

This cross-sectional study aimed to investigate developmental changes in the efficiency of sustained, selective, and divided attention in a group of children aged 6-12 years by means of a computerized test battery. Participants included 199 children (51% female, majority White) who had normal or corrected-to-normal vision and no history of either…

Purpose: An internal model deficit is considered to underlie developmental coordination disorder (DCD); thus, children with DCD have an altered sense of agency (SoA), which is associated with depressive symptoms. Furthermore, the perception of action-outcome regularity is present in early development, is involved in the generation of SoA, and has…

Background: Individuals with Down syndrome are an at-risk population for severe COVID-19 outcomes, due to genetic predispositions and comorbidities. The current study focused on differences between persons with and without Down syndrome regarding age and severity of disease. Method: We used medical statistics to compare patients with and without…

Considerable scholarly attention has been dedicated toward the role of peers in adolescents' romantic lives (Brown, 1999; Collins, 2003; Connolly & McIsaac, 2009, Korobov & Thorne, 2006). However, when it comes to the developmental significance of adults in promoting the healthy romantic functioning of adolescents, there has been…

Idioms, along with other formulaic multiword phrases, represent a substantial part of vocabulary knowledge. This study investigates how idiom knowledge develops through the adult lifespan, comparing familiarity and transparency ratings for a large set of common English idioms. A total of 237 participants, ranging from 18 to 77 years old,…

There is evidence that mastery motivation contributes to developmental outcomes, both for typically developing individuals and for those with disabilities such as Down syndrome. Mastery motivation appears to be a stable trait, at least during early childhood, but research with adults has been restricted by the absence of an appropriate measure.…
