Abstract
Attention Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders, affecting 3 to 5 percent of school-age children. This disorder is divided into three subtypes based on differential elevations of inattention and hyperactivity-impulsivity symptoms: inattentive type (ADHD-I), hyperactive-impulsive type (ADHD-HI), and combined type (ADHD-C).
Working memory is one of the most widely used terms in psychology which is defined as the small amount of information that can be held in mind and used in the execution of cognitive tasks, in contrast with long-term memory, which is the vast amount of information saved in one’s life. It has often been connected or related to intelligence, information processing, executive function, comprehension, problem solving, and learning in people ranging from infancy to old age.
Moreover, Working Memory (WM) impairment is considered a significant cognitive feature differentiating between ADHD and non-ADHD children.
Rapid automatizing naming (RAN) is the ability to identify and recognize a given item through the activation and concomitant articulation of its name, which will later be stored in the mental lexicon.
Rapid Automatized Naming (RAN), a task in which participants must name a series of items as rapidly as possible, has been very useful as a measure of cognitive abilities that predict reading skill both in children and in young adults (YAs).
Several studies have demonstrated that digits and letters are named faster and more accurately than objects and colors.
RAN tasks depend on automaticity within and among each individual component in the naming circuit. It is within this context RAN is being considered to be a universal processes that predict the young child’s ability to connect and automatize the sequences of letters and words with their linguistic information.
The aim of this study was to assess the rapid automatized naming deficits (in speed and accuracy) in cases of ADHD to investigate other cognitive deficits related to ADHD to be incorporated in management plan if proved.
After the application of RAN test on 30 children were diagnosed as ADHD The results obtained in the current study showed that 80% of the participating patients had longer response times (i.e., inter-item pauses) apparent in the performance of children with ADHD, with no significant in between the different types of ADHD.
