“…Compared to the child population, relatively little is known about the neurological and cognitive profiles of adults with ADHD; however, what evidence is available suggests continued symptomatology at least partially similar to children with ADHD. Specifically, adults with the disorder continue to have attentional problems (Sandson, Bachna, & Morin, 2000; Hollingsworth, McAuliffe, & Knowlton, 2001), other executive functioning deficits (Nigg et al, 2005; Lovejoy et al, 1999), and working memory deficits (Murphy, Barkley, & Bush, 2001). An expanding literature has begun to identify inhibitory control deficits in this group (Carr, Nigg, & Henderson, 2006; Feifel, Farber, Clementz, Perry, & Anllo-Vento, 2004; Armstrong & Munoz, 2003; Ross, Harris, Olincy, & Radant, 2000).…”

Researchers in the cognitive sciences recognize a fundamental distinction between automatic and intentional mechanisms of inhibitory control. The use of eye-tracking tasks to assess selective attention has led to a better understanding of this distinction in specific populations such as children with attention-deficit/hyperactivity disorder (ADHD). This study examined automatic and intentional inhibitory control mechanisms in adults with ADHD using a saccadic interference (SI) task and a delayed ocular response (DOR) task. Thirty adults with ADHD were compared to 27 comparison adults on measures of inhibitory control. The DOR task showed that adults with ADHD were less able than comparison adults to inhibit a reflexive saccade towards the sudden appearance of a stimulus in the periphery. However, SI task performance showed that the ADHD group did not differ significantly from the comparison group on a measure of automatic inhibitory control. These findings suggest a dissociation between automatic and intentional inhibitory deficits in adults with ADHD.

“…In multiple visual-spatial tasks intended for right hemisphere processing assessment in children from 14 to 16 years old, right hemisphere dysfunction was reported, and adults with ADHD were also impaired on a letter cancellation task. Teenagers and adults with ADHD demonstrated a higher mean left-sided omission rate than healthy controls 3,4. Visual perception problem in children with ADHD have been reported, however, little is known about the factors of visual perception in ADHD children.…”

ObjectiveThe aim of the present study was to investigate the visual perception difference between ADHD children with and without sensory processing disorder, and the relationship between sensory processing and visual perception of the children with ADHD.MethodsParticipants were 47 outpatients, aged 6-8 years, diagnosed with ADHD. After excluding those who met exclusion criteria, 38 subjects were clustered into two groups, ADHD children with and without sensory processing disorder (SPD), using SSP reported by their parents, then subjects completed K-DTVP-2. Spearman correlation analysis was run to determine the relationship between sensory processing and visual perception, and Mann-Whitney-U test was conducted to compare the K-DTVP-2 score of two groups respectively.ResultsThe ADHD children with SPD performed inferiorly to ADHD children without SPD in the on 3 quotients of K-DTVP-2. The GVP of K-DTVP-2 score was related to Movement Sensitivity section (r=0.368*) and Low Energy/Weak section of SSP (r=0.369*).ConclusionThe result of the present study suggests that among children with ADHD, the visual perception is lower in those children with co-morbid SPD. Also, visual perception may be related to sensory processing, especially in the reactions of vestibular and proprioceptive senses. Regarding academic performance, it is necessary to consider how sensory processing issues affect visual perception in children with ADHD.

“…Several lines of evidence have already demonstrated that children with ADHD-type symptoms have comorbid deficits in visual and auditory processing (Cook et al 1993;Epstein et al 1997;Keith and Engineer 1991;Sandson et al 2000;Shapiro and Herod 1994;Tillery et al 2000). Research investigating visual deficits in children with symptoms of ADHD highlights the fact that these children lack perceptual sensitivity, resulting in slowed processing and poor evaluation of visual stimuli, both of which are associated with inattentiveness and behavior problems (Swaab-Barneveld et al 2000).…”

Relationship Between Sensory Deficits and Externalizing Behaviors in an Urban, Latino Preschool Population

This study examined the relationship between sensory deficits and externalizing behavior problems in preschool children. Parents of 179 urban, Latino preschool children completed two parent-report measures, the Short Sensory Profile (SSP), as a checklist for sensory symptoms, and the Achenbach Checklist for Ages 1-5 (CBCL/1-5) to assess externalizing behavior problems. Measures were available in Spanish or English depending on the parent's preference. Correlations were performed between the total sensory deficits scale of the SSP and the Oppositional Defiant Disorder, Attention Deficit Hyperactivity Disorder, and Externalizing Problems scales of the CBCL. Significant correlations were found between increasing levels of sensory deficits and increasing externalizing behavior problems. Correlations were also examined in subcategories of age, gender and socioeconomic status. Five-year-old children showed stronger correlations than 4-year-old children, while males showed stronger correlations than females, and the highest correlations were found in children of families reporting between $18,001 and $24,000 per year annual income. Findings suggest that Latino preschool children with externalizing behavior problems may suffer from delays in sensory development that impact their behavior. Clinical interventions should promote strategies that either reduce or increase environmental stimuli in accordance with the sensory abilities of the individual child.
