Excess adipose tissue may impact the motor performance of youth. Therefore, the current study examined: (1) if adiposity influenced performance in the jump and reach and 30-yard dash; and (2) if maturation predicted motor performance. Participants (N = 267) included girls aged 8 to 16 years. Latent growth curves were used to assess changes in…

Purpose: To estimate temporal trends in broad jump performance for United States youth, a marker of muscular fitness and health. Method: Electronic databases, topical systematic reviews, and personal libraries were systematically searched for studies reporting descriptive standing broad jump data for apparently healthy United States youth (age…

Children perform worse than adults on tests of cognitive flexibility, which is a component of executive function. To assess what aspects of a cognitive flexibility task (cued switching) children have difficulty with, investigators tested where eye gaze diverged over age. Eye-tracking was used as a proxy for attention during the preparatory period…

This study aimed to analyze whether judo experience, somatic maturation, growth, and physical capacities discriminate young judo athletes from different competitive levels (state and national). Sixty-six young male judo athletes (36 from state and 30 from national level) participated in this study, divided from the annual competitive season. The…

The aim of this study consists of the analysis of certain differences in motor skills of male children who are sedentary and in the age group of 9-14, in relation to the biological maturity. 522 sedentary male children from various parts of Turkey participated in this study. Body height and body weight measurements were taken from the participants…

Evidence that the transition to parenthood is occurring at older ages in the Western world, that older parents provide more growth-facilitating care than do younger ones, and that most prospective studies of the intergenerational transmission of parenting have focused on relatively young parents led us to evaluate whether parental age might…

Purpose: The goal was to assess the effects of maturation and phonological development on performance, by normally hearing children, on an imitative test of auditory capacity (On-Line Imitative Test of Speech-Pattern Contrast Perception [OlimSpac]; Boothroyd, Eisenberg, & Martinez, 2006; Eisenberg, Martinez, & Boothroyd, 2003, 2007). Method:…

There is strong evidence that developments in children's theory of mind (ToM) at 3-4 years are related to developments in language and executive function. However, these relationships might exist for 2 reasons. First, language and executive function might be necessary for the mature ToM abilities that children are in the process of developing.…

Aim: To study the aetiology of intellectual disability in patients presenting to hospital and the diagnostic yield of a standardized examination. Method: Over a 1-year period, the first three children presenting to the paediatric outpatients department (OPD) on 2 selected weekdays with developmental delay, suspected intellectual disability, or…

Study aim: To compare two exercise training modes on the physical fitness of 10 year-old children. Material and methods: A sample of 60 schoolboys aged 10 years were randomly divided into 3 groups: Traditional (TG), trained according to the Brazilian national curricular parameters, Maturational (MG), in which the degree of difficulty of the…

Historically, it was believed the perceptual mechanisms involved in individuating faces developed only very slowly over the course of childhood, and that adult levels of expertise were not reached until well into adolescence. Over the last 10 years, there has been some erosion of this view by demonstrations that all adult-like behavioural…

Typically language development in children closely coincides with development in many other areas. This makes it difficult to determine whether observed correlations are coincidental or causal in nature. The three studies presented here explore these relationships by looking at two populations of learners who are delayed in exposure to English,…

Among girls observed interacting with infants, older girls ignored more, made fewer social bids, and responded less than younger girls. However, chronological age was highly correlated with measures of social and biological maturity. Social maturity was the best predictor of trends on two interaction measures, biological maturity on the third.…

The study examined the developmental lag hypothesis for learning disabilities by evaluating dichotic listening ability using both free recall and directed attention conditions in 24 learning disabled (LD) adults. Findings indicated LD adults showed similar deficits in lateralized selective auditory linguistic processing as children with LD. (DB)

Investigated beliefs about feeling the stares of an unseen other. Found that most adults and young children believed they could feel the unseen stares of another, and across age there were some increases in beliefs about the feeling. Participants believed that in order to feel stares, some cognitive maturity was required. (MOK)
