Adolescents with attention-deficit/hyperactivity disorder (ADHD) are at heightened risk of experiencing academic difficulties due to organizational deficits. Impairment can be exacerbated through poor sleep hygiene and excessive daytime sleepiness, prevalent sleep challenges for adolescents with ADHD. Given established relationships among sleep,…

Malingering is a significant assessment concern in adults undergoing evaluations for attention deficit/hyperactivity disorder (ADHD) and may occur for a number of reasons, including access to medication and/or accommodations. Therefore, it is important to investigate ways to determine accuracy of self-reported ADHD symptoms. The present study used…

Background: Episodic autobiographical memory (EAM) has not been extensively investigated in children with attention-deficit/hyperactivity disorder (ADHD). The objective of this study was to examine EAM in school-age children with ADHD in reference to the encoding period: recent memories (previous school years) and remote memories (first years of…

Concurrent associations between teacher ratings of inattention, hyperactivity and pre-reading skills were examined in 64 pre-schoolers who had not commenced formal reading instruction and 136 school entrants who were in the first weeks of reading instruction. Both samples of children completed measures of pre-reading skills, namely phonological…

The multimedia elements of text and audio need to be carefully integrated together to maximize the impact of those elements for learning in a multimedia environment. Redundancy information presented through audio and visual channels can inhibit learning for individuals diagnosed with ADHD, who may experience challenges in the processing of…

Differentiating between early-onset bipolar disorder (BD) and attention-deficit/hyperactivity disorder (ADHD) can be difficult. Memory problems are commonly reported in BD, and forgetfulness is among the diagnostic criteria for ADHD. We compared children and adolescents with BD (n = 23), ADHD combined type (ADHD-C; n = 26), BD + ADHD-C (n = 15),…

Relationships between attention/executive functions and language learning were investigated in students in Grades 4 to 9 (N = 88) with and without specific learning disabilities (SLDs) in multiword syntax in oral and written language (OWL LD), word reading and spelling (dyslexia), and subword letter writing (dysgraphia). Prior…

Visual and auditory verbal learning using a selective reminding format was studied in a mixed clinical sample of children with autism spectrum disorder (ASD) (n = 42), attention-deficit hyperactivity disorder (n = 83), velocardiofacial syndrome (n = 17) and neurotypicals (n = 38) using the Test of Memory and Learning to (1) more thoroughly…

The basic deficits underlying the severe and persistent reading difficulties in dyslexia are still highly debated. One of the major topics of debate is whether these deficits are language specific, or affect both verbal and non-verbal stimuli. Recently, Ahissar and colleagues proposed the "anchoring-deficit hypothesis" (Ahissar, Lubin,…

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…

As a group, participants with attention-deficit/hyperactivity disorder (ADHD) are impaired in academic performance and learning. This may be due to a mild intellectual impairment, impaired attention, or inability to allocate sufficient effort. If the latter is the case, this should be evident in the learning strategies applied. Four indices of…

Background: Although distinctive neuropsychological impairments have been delineated in children with chromosome 22q11 deletion syndrome (22q11DS), social skills and social cognition remain less well-characterised. Objective: To examine social skills and social cognition and their relationship with neuropsychological function/behaviour and…

An aspect of metacognition, metamemory (knowledge and awareness of one's memory) was investigated across time in preschool children with ADHD (n = 31) and a sample of age, sex, socioeconomic and IQ-matched typically developing children (n = 31). Only children with stable ADHD diagnoses were included. Participants were assessed on a variety of…

Objectives: To demonstrate that high IQ adults diagnosed with ADHD suffer from executive function (EF) impairments that: a) can be identified with a combination of standardized measures and self-report data; and b) occur more commonly in this group than in the general population. Method: 157 ADHD adults with IQ greater than or equal to 120 were…

Intelligence tests are usually part of the assessment battery for the diagnosis of adults with learning disabilities (LD) and attention deficit hyperactivity disorder (ADHD). Professionals must ensure that inferences drawn from such test scores are equivalent across populations with and without disabilities. Examination of measurement equivalence…
