Students with Attention-Deficit/Hyperactivity Disorder (ADHD) are struggling writers. Yet no comprehensive model has been validated to explain their poor writing outcomes. This study aims to test whether an extended version of the Not-So-Simple View of Writing (NSVW) model can describe the effects of key abilities on writing performance in…

This study is a conceptual replication of a widely cited study by Moffitt et al. (2011) which found that attention and behavior problems in childhood (a composite of impulsive hyperactive, inattentive, and impulsive-aggressive behaviors labeled "self-control") predicted adult financial status, health, and criminal activity. Using data…

This study investigated the prevalence and stability of latent classes at risk for reading disabilities (RD) in elementary-aged children whose first language is Spanish. To this end, children (N = 489) in Grades 1, 2, and 3 at Wave 1 were administered a battery of reading, vocabulary, and cognitive measures (short-term memory [STM], working memory…

The study assessed cognitive and academic performance of children demonstrating teacher-rated ADHD-related symptoms (Inattention [IA] and/or Hyperactivity/Impulsivity [H/I]) in a representative sample of, largely untreated, Greek elementary school students (N?=?923). A battery of tests assessing short-term memory (STM), sustained attention,…

Few evidence-based practices are available to guide educators in teaching reading to children with Autism Spectrum Disorder who have complex learning and behavioral needs associated with the symptoms of ASD and common co-occurring conditions, such as Attention Deficit/Hyperactive Disorder and Specific Learning Disability. Some researchers have…

Difficulties in peer acceptance during elementary school have been associated with emotional and behavioural problems. This study used a randomized controlled intervention design to test whether improvements in peer acceptance mediated reduced rates of emotional and behavioural problems in intervention compared to control-group children. A total…

Purpose: Successful communication requires that listeners accurately interpret the meaning of speakers' statements. The present work examined whether children with and without attention-deficit/hyperactivity disorder (ADHD) differ in their ability to interpret referential statements (i.e., phrasesthat denote objects or events) from speakers.…

To further explore contextual reading rate, an important aspect of reading fluency, we examined the relationship between word reading efficiency (WRE) and contextual oral reading rate (ORR), the degree to which they overlap across different comprehension measures, whether oral language (semantics and syntax) predicts ORR beyond contributions of…

This study examined how ADHD symptoms in mothers of children with ADHD relate to their behavior during parent-child interactions and to their children's disruptive behavior. Findings indicated that mothers' retrospective self-ratings of ADHD symptoms were related to their present negativity during parent-led play. Mothers' self-ratings of current…

Substantial experimental evidence indicates that behavior reinforced on a denser schedule is more resistant to disruption than is behavior reinforced on a thinner schedule. The present experiment studied resistance to disruption in a natural educational environment. Responding during familiar activities was reinforced on a multiple…

Impulsivity and inattention are key constructs at the interface of temperament and domains of childhood behavioral problems, such as ADHD and ODD. A multi-method, multi-source assessment of impulsivity and inattention was conducted with 256 families of twins at a mean age of 8-9 years from an epidemiologically defined community sample. Analysis of…
