A meta-analysis of working memory impairments in children with attention-deficit/hyperactivity disorder.
Evidence of WM impairments in children with ADHD supports recent theoretical models implicating WM processes in ADHD and is needed to more clearly delineate the nature, severity, and specificity of the impairments to ADHD.
Neuroscience of attention-deficit/hyperactivity disorder: the search for endophenotypes
It is proposed that three such endophenotypes — a specific abnormality in reward-related circuitry that leads to shortened delay gradients, deficits in temporal processing that result in high intrasubject intertrial variability, and deficits in working memory — are most amenable to integrative collaborative approaches that aim to uncover the causes of ADHD.
Impulsivity and Inhibitory Control
We report an experiment testing the hypothesis that impulsive behavior reflects a deficit in the ability to inhibit prepotent responses Specifically, we examined whether impulsive people respond more
Validity of DSM-IV attention deficit/hyperactivity disorder symptom dimensions and subtypes.
The DSM-IV ADHD subtypes provide a convenient clinical shorthand to describe the functional and behavioral correlates of current levels of inattention and hyperactivity-impulsivity symptoms, but do not identify discrete subgroups with sufficient long-term stability to justify the classification of distinct forms of the disorder.

The available data do not yet permit an integration across these different levels of enquiry, but implicate problems in response inhibition, dysfunction of frontostriatal networks, and genetic factors in the pathogenesis of this complex behavioral phenotype.
Development of inhibitory control across the life span.
Results indicated the speed of stopping becomes faster with increasing age across childhood, with limited evidence of slowing across adulthood, while strong evidence was obtained for age-related speeding of go-signal reaction time throughout childhood, followed by marked slowing throughout adulthood.
Neuropsychological profiles of adolescents with ADHD: effects of reading difficulties and gender.
This study challenges the importance of behavioral inhibition deficits in ADHD and that naming deficits are specific to RD and further investigation into cognitive deficits in these groups is required.
Phase 2 of CATALISE: a multinational and multidisciplinary Delphi consensus study of problems with language development: Terminology
This Delphi exercise highlights reasons for disagreements about terminology for language disorders and proposes standard definitions and nomenclature.
The Development of Selective Inhibitory Control Across the Life Span
Results indicated that SSRT gets faster with increasing age throughout Childhood, with pronounced slowing in older adulthood, and strong evidence was obtained for age-related speeding in GoRT throughout childhood, with marked slowing throughout adulthood.
