In this work, the position of the goals was modified to analyze the effects on the exploratory behavior and the team tactical pattern, which can be meaningful variables to study creativity in team sports. Twenty-four male soccer school players under the age of 12 participated in this study. Participants were divided into four teams of one…

Objectives: The aim of this study was to assess the motor profile of children with attention deficit hyperactivity disorder (ADHD), combined type. Method: The case group consisted of 34 treatment-naive, male patients, aged 7-11 years, who had been diagnosed with ADHD, combined type, without comorbidities (except oppositional defiant disorder). The…

Japan has been considered dyslexia-free because of the nature of the orthography, which consists of the visually simple kana syllabary and some thousands of visually complex, logographic kanji characters. It is true that few children struggle with learning kana, which provide consistent mappings between symbols and their pronunciation. Indeed,…

Previous research into face processing in autism spectrum disorder (ASD) has revealed atypical biases toward particular facial information during identity recognition. Specifically, a focus on features (or high spatial frequencies [HSFs]) has been reported for both face and nonface processing in ASD. The current study investigated the development…

Aim: Although approximately 40% of children with neurofibromatosis type 1 (NF1) meet diagnostic criteria for attention-deficit-hyperactivity disorder (ADHD), the impact of ADHD on the executive functioning of children with NF1 is not understood. We investigated whether spatial working memory and response inhibition are impaired in children with…

Lateralization of the brain is strongly influenced by prenatal androgens, with differential exposure thought to account for cognitive sex differences. This study investigated sex and individual differences and relationships between 2D:4D (the ratio of the 2nd to 4th digit [digit ratio] as a proxy indicator of prenatal testosterone exposure),…

Background: Working memory problems have been targeted as core deficits in individuals with Fragile X syndrome (FXS); however, there have been few studies that have examined working memory in young boys with FXS, and even fewer studies that have studied the working memory performance of young boys with FXS across different degrees of complexity.…

Objective: To determine whether 7- to 12-year-old boys with ADHD, relative to non-ADHD age-mates, exhibit greater difficulty learning and remembering object locations. The second purpose was to examine the functional utility of mnemonic strategies, specifically speech-to-self, used by boys with and without ADHD. Method: Boys with and without ADHD…

Hyperactivity is currently considered a core and ubiquitous feature of attention-deficit/hyperactivity disorder (ADHD); however, an alternative model challenges this premise and hypothesizes a functional relationship between working memory (WM) and activity level. The current study investigated whether children's activity level is functionally…

Objective: The goal of this study was to contrast the cognitive phenotypes in boys with 47,XYY (XYY) karyotype and boys with 47,XXY karyotype [Klinefelter syndrome, (KS)], who share an extra copy of the X-Y pseudoautosomal region but differ in their dosage of strictly sex-linked genes. Methods: Neuropsychological evaluation of general cognitive…

Executive functions, including inhibition, have been implicated in children's reading ability. This study investigates whether children's performance on an inhibition task is more indicative of reading ability than a measure of another executive function, that is, planning. Fifty-three male participants were administered a reading test and tests…

These proceedings contain the papers of the 16th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2019), held during November 7-9, 2019, which has been organized by the International Association for Development of the Information Society (IADIS) and co-organised by University Degli Studi di Cagliari, Italy.…

Data from a battery of spatial tests taken by children six to 18 years old indicate that a male advantage in spatial performance appears reliably by age 10, and that the magnitude of the advantage remains constant through age 18. (PCB)

Background: Accumulating evidence supports methylphenidate-induced enhancement of neuropsychological functioning in attention deficit hyperactivity disorder (ADHD). The present study was designed to investigate the acute effects of the psychostimulant drug, methylphenidate (MPH), on neuropsychological performance in stimulant naive boys with ADHD.…

Background: Sex-differences exist in some areas of human social behaviour. In animals, foetal testosterone (fT) plays a central role in organising the brain and in later social behaviour. fT has also been implicated in language development, eye-contact, and spatial ability in humans. Methods: Fifty-eight children (35 male and 23 female), whose fT…
