Background and Aims: Epidemiological studies have provided invaluable insight into the origin and impact of low language skills in childhood and adolescence. However, changing terminology and diagnostic guidelines have contributed to variable estimations of the prevalence of developmental language difficulties. The aim of this review was to…

The distance between the birth date and the school entry cutoff has been repeatedly used as an exogenous instrument to examine the impact of several educational programmes. In this work, we analyse the validity of this instrument for the case of Argentina. Considering multiple waves of the Permanent Household Survey we detect the existence of…

Research on gesture development has mostly focused on home environments. Little is known about early communicative development in other relevant contexts, such as early-year-schools. These settings, rich in diverse educative situations, objects, and communicative partners, provide a contrast to parent-child interactions, complementing our…

This research explored early ecological-moral sense, by investigating 2.5- and 5-year-old children's evaluations of overt and covert pro-environmental actions using both rewarding and reaching paradigms (N = 96; 100% White). In Experiment 1, the overt pro-environmental action was compared with the action of harming the environment. In Experiment…

In the context of an ongoing national conversation about teacher shortages, we build on prior literature on the efficacy of teacher certification pathways by comparing entry and exit patterns based on age at the time of certification. All trainees who complete a state certification process have invested substantial time and resources into entering…

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…

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,…

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…
