The term "camouflaging" describes behaviors that cover up neurodivergent difficulties. While researched in autism, camouflaging has received no systematic study in other conditions affecting communication, including developmental language disorder (DLD). This study explored camouflaging in DLD, drawing on the experience and expertise of…

The development of the ability to anticipate--as manifested by preparatory actions and neural activation related to the expectation of an upcoming stimulus--may play a key role in the ontogeny of cognitive skills more broadly. This preregistered study examined anticipatory brain potentials and behavioral responses (reaction time; RT) to…

Cognitive effort is costly and this cost likely influences the activities in which children engage. Yet, little is known about how school-age children perceive cognitive effort. The subjective value of cognitive effort, that is, how valuable or costly effort is perceived, was investigated in seventy-three 7- to 12-year-olds using an effort…

Educational Robotics in Greece is being used increasingly, while it is hesitantly applied in Special Education as it requires a properly educational trained staff. The present study is a case study aiming to discuss the effects of the utilization of educational robotics in a Special Education School classroom and specifically on students with…

Lying is an interpersonal exercise that requires the intentional creation of a false belief in another's mind. As such, children's development of lie-telling is related to their increasing understanding of others and may reflect the acquisition of basic social skills. Although certain types of lies may support social relationships, other types of…

Prevalence of self-injurious behavior (SIB) is as high as 50% among children with autism spectrum disorder (ASD). Identification of risk factors for the development of SIB is critical to early intervention and prevention. However, there is little empirical research utilizing a prospective design to identify early risk factors for SIB. The purpose…

The structure of the human brain changes in several ways throughout childhood and adolescence. Perhaps the most salient of these changes is the strengthening of white matter tracts that enable distal brain regions to communicate with one another more quickly and efficiently. Here, we sought to understand whether and how white matter changes…

Objective: The study investigates behavioural, academic, cognitive, and motivational aspects of functioning in school-age children with attention-deficit/hyperactivity disorder (ADHD) with and without an executive function deficit (EFD). Method: Children with ADHD - EFD (n = 22) and children with ADHD + EFD (n = 26) were compared on aspects of…

This study examined the relationship between everyday repetitive behavior (primary symptoms of autism) and performance on neuropsychological tests of executive function and central coherence (secondary symptoms). It was hypothesized that the frequency and intensity of repetitive behavior would be positively correlated with laboratory measures of…

Cognitive and behavioral effects of temporarily elevating levels of phenylalanine in treated phenylketonuria (PKU) were investigated in a triple-blind crossover study with 16 early and continuously treated children and adolescents with PKU. Results suggest that intellectual ability, memory, and conduct are not affected by medium-term elevated…

Tests of executive functions and control tasks not assessing executive function were administered to 19 individuals (ages 6-28) mild hyperphenylalaninemia (MHP) and 19 controls. Tests of academic skills and behavior-rating questionnaires were also administered to the group with MHP. No group differences were found for any measure. (Contains…

Although sports are a part of the child's everyday experience, little is known about factors that relate to children's participation in sports, to their perceptions of self-competence in sports, and to the impression by others of the competence. Children (N=110) participating in a Pediatric Sports Medicine Project completed the psychological…

Parents of 42 children (ages 2-32) with Lesch-Nyhan disease were questioned concerning the subjects' behavior patterns. Grouping of responses into nine categories of cognitive skills indicated that only one boy showed any significant cognitive impairment. Despite evidence of good cognitive and emotional skills, subjects were academically delayed,…

This study presents data on the physical, developmental, and behavioral characteristics of a group of 203 nonambulatory persons with profound mental retardation. It found a high prevalence of physical and medical problems, as well as high rates of self-injurious, stereotypic, and aggressive behavior and high variability in cognitive and adaptive…

Reports the results of cognitive test performance and early childhood activities in individuals with congenital adrenal hyperplasia, an autosomal recessive disorder associated with elevated prenatal adrenal androgen levels, demonstrating the effects of early exposure to excess androgenizing hormones on sexually dimorphic cognitive functioning.…
