Background: Children with attention deficit/hyperactivity disorder (ADHD) display abnormalities in reward processing. Most reward studies have focused on the effects of material or monetary rewards. Studies with autism spectrum disorder (ASD) have focused on social rewards. In this study we compared the effects of amount and type of reward in…

Background: To investigate links between inhibitory control (IC) and behavior problems in early childhood, as well as genetic and environmental covariances between these two constructs. Methods: Parent and laboratory ratings of IC and parent ratings of externalizing and attention deficit hyperactivity disorder behaviors were administered at 24…

The present study investigated the prevalence of ADHD in a school sample of children ages 6-11 years in the city of Panama. The assessment battery included the Conners' Parent and Teacher Rating Scales, the Structured Developmental History of the Behavioral Assessment System for Children (BASC-2), and the Wechsler Intelligence Scale for Children…

Research indicates peer socialization processes affect the development of problem behavior in childhood and adolescence; however moderating peer factors have not been readily examined. Friendship intimate exchange may be an important factor to consider, as literature suggests that intimate exchange becomes an increasingly important aspect of…

Functional magnetic resonance imaging (fMRI) during performance of a hidden figures task (HFT) was used to compare differences in brain function in children diagnosed with autism disorder (AD) compared to children with attention-deficit/hyperactivity disorder (ADHD) and typical controls (TC). Overall greater functional MRI activity was observed in…

This study aimed to compile a screening scale for high-functioning pervasive developmental disorders (PDD), using the Tokyo Child Development Schedule (TCDS) and Tokyo Autistic Behavior Scale (TABS). The 72 participants (IQ greater than or equal to 70) were divided into 3 groups after IQ matching depending on their diagnoses: i.e., PDD,…

This systematic review sought to understand the individual characteristics of incarcerated youth within the major risk factor domains identified by the U.S. Office of Juvenile Justice and Delinquency Prevention (OJJDP). A comprehensive search of the literature from 1979 to 2013 identified 85 articles of individual-level risk characteristics that…

Published for over a decade, this directory continues to be a successful, sought-after resource, providing valuable information to professionals, families, and individuals in the learning disabilities community. Supported by the National Center for Learning Disabilities, this 2017 edition brings together the most up-to-date information on LD…

This study examined the effects of an intervention consisting of automated prompting and self-monitoring on the level of independent homework task completion for an elementary-age student with attention deficit hyperactivity disorder (ADHD). Instituting a single subject, within series ABAB design, the results showed a consistent increase and…

Background: Families of children with attention deficit hyperactivity disorder (ADHD) report more negative family relationships than families of children without ADHD. Questions remain as to the role of genetic factors underlying associations between family relationships and children's ADHD symptoms, and the role of children's ADHD…

Communication and play skills are important aspects of development yet are largely uncharted in children with attention deficit hyperactivity disorder (ADHD). This exploratory study examined whether changes in pragmatic skills and problem-solving skills were observed in children with ADHD pre- and post-participation in a play-based intervention…

The current study examined the incremental utility of rating scales, a structured diagnostic interview, and multiple informants in a comprehensive assessment of attention-deficit/hyperactivity disorder (ADHD). The sample included 185 children with ADHD (M[subscript age] = 9.22, SD = 0.95) and 82 children without ADHD (M[subscript age] = 9.24, SD =…

The aim of this study was to investigate the specific numerical and calculation abilities of 28 children with ADHD without comorbid mathematical learning disabilities (LD), ranging from the 1st to the 5th grade of primary school, and to examine the stability or the development of the arithmetic profile. Our results showed that a high percentage of…

Objective: Additional treatments with persisting benefit are needed for ADHD. Because ADHD often shows excessive theta electroencephalogram (EEG) power, low beta, and excessive theta-beta ratio (TBR), a promising treatment is neurofeedback (NF) downtraining TBR. Although several nonblind randomized clinical trials (RCTs) show a medium-large…

This study examined teachers' attitudes toward learners with two types of barriers to learning: a learner with attention-deficit and hyperactivity disorder (ADHD), and a learner with little or no functional speech (LNFS). The results indicated that although teachers reported that the learner with ADHD would be more disruptive in class and have a…
