Spelling errors among children with ADHD symptoms: The role of working memory

AbstractBackgroundAttenuated inhibitory control is one of the most robust findings in the neuropsychology of attention-deficit/hyperactivity disorder (ADHD). However, it is unclear whether this represents a deficit in outright stopping (reactive inhibition), whether it relates to a deficit in anticipatory response slowing (proactive inhibition), or both. In addition, children with other development disorders, such as autism spectrum disorder (ASD), often have symptoms of inattention, impulsivity, and hyperactivity similar to children with ADHD. These may relate to similar underlying changes in inhibitory processing.MethodsIn this study, we used a modified stop-signal task to dissociate reactive and proactive inhibition. We included not only children with ADHD, but also children primarily diagnosed with an ASD and high parent-rated levels of ADHD symptoms.ResultsWe replicated the well-documented finding of attenuated reactive inhibition in children with ADHD. In addition, we found a similar deficit in children with ASD and a similar level of ADHD symptoms. In contrast, we found no evidence for deficits in proactive inhibition in either clinical group.ConclusionsThese findings re-emphasize the role of reactive inhibition in children with ADHD and ADHD symptoms. Moreover, our findings stress the importance of a trans-diagnostic approach to the relationship between behavior and neuropsychology.

Objective: The aim of the present study was to examine the effect of comorbid oppositional defiant disorder (ODD) and conduct disorder (CD) on (i) symptom levels in attention-deficit–hyperactivity disorder (ADHD) and (ii) the relationship between neurocognitive impairment and ADHD symptom severity. Method: A total of 200 6–12-year-old children with DSM-IV ADHD, combined type (ADHD-CT) were identified in a specialist ADHD clinic in metropolitan Melbourne. From this initial group, 23 were identified with ADHD without ODD/CD (ADHD alone), 22 had ADHD and ODD and 20 had ADHD and CD. All the children were medication naïve. Twenty-five healthy control children were also recruited from local primary schools. The four groups did not differ in age, gender or full-scale IQ. A cross-sectional study of parent- and teacher-reported ADHD and externalizing symptoms, spatial span, spatial working memory, visuospatial memory, spatial recognition, spatial planning and behavioural inhibition was completed. Results: Parent-reported externalizing symptoms were higher in the ADHD + CD and ADHD + ODD groups compared to the ADHD alone group. There were no differences in neurocognitive function between children with ADHD-CT with and without ODD or CD. All the ADHD groups, however, performed worse than the healthy control group. Further, worse spatial span, spatial working memory and delayed matching to sample performance were associated with increased teacher-reported ADHD symptoms in the ADHD alone group. Also, worse spatial working memory performance was associated with increased teacher-reported ADHD symptoms in the ADHD + CD group. Conclusions: ADHD symptom severity is associated with the magnitude of impairment in executive functions in children with ADHD alone, but these relationships can be obscured by the presence of comorbid disruptive disorders. Children with ADHD + CD may demonstrate similar associations to children with ADHD alone, suggesting a similar underlying dysfunction. ADHD + ODD, however, may be better understood as a maladaptive response to the abnormal behaviours and neurocognitive functions in ADHD.

Children With Adhd

An operational definition of mind wandering is when one has thoughts unrelated to the current task(s) (Smallwood & Schooler, 2015). Mind blanking can be thought of as a subtype of mind wandering where there is an inability to report the content of these task-unrelated thoughts. Van den Driessche et al. (2017) found that children and young adults with more Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms report more mind blanking than those with fewer ADHD symptoms and that non-medicated children with ADHD reported less mind wandering and more mind blanking than medicated children with ADHD. Van den Driessche et al. speculated that medication facilitated executive control and that executive resources support mind wandering (and on-task thought). These findings also bear on the theoretical debate on the role of executive functions in conscious experience. Some argue that executive functions support mind wandering (Levinson et al., 2012; Smallwood, 2010), while others argue and that mind wandering situationally results from a lack (or failure) of executive control (McVay & Kane, 2010; Meier, 2019). In this study, with a young adult sample, I tested the association between ADHD symptomology and conscious experience and if executive resources moderate the proportion of reporting mind blanking and mind wandering. The current study found evidence for Van den Driessche et al.’s finding of a positive and significant association between mind blanking and ADHD symptomology. The current study was also broadly consistent with Van den Driessche et al.’s finding of an ADHD-related trade-off involving mind blanking, but importantly differs from Van den Driessche et al. in that mind wandering was not involved in this trade-off. The current study did not find an association between working memory capacity and mind wandering. Thus, I found no evidence for executive resources supporting mind wandering, consistent with previous studies (McVay & Kane, 2009, 2012a, 2012b; Meier, 2019; Robison & Unsworth, 2018; Unsworth & McMillan, 2013, 2014).

Abstract. Objective: Deficits in basic numerical skills, calculation, and working memory have been found in children with developmental dyscalculia (DD) as well as children with attention-deficit/hyperactivity disorder (ADHD). This paper investigates cognitive profiles of children with DD and/or ADHD symptoms (AS) in a double dissociation design to obtain a better understanding of the comorbidity of DD and ADHD. Method: Children with DD-only (N = 33), AS-only (N = 16), comorbid DD+AS (N = 20), and typically developing controls (TD, N = 40) were assessed on measures of basic numerical processing, calculation, working memory, processing speed, and neurocognitive measures of attention. Results: Children with DD (DD, DD+AS) showed deficits in all basic numerical skills, calculation, working memory, and sustained attention. Children with AS (AS, DD+AS) displayed more selective difficulties in dot enumeration, subtraction, verbal working memory, and processing speed. Also, they generally performed more poorly in neurocognitive measures of attention, especially alertness. Children with DD+AS mostly showed an additive combination of the deficits associated with DD-only and A_Sonly, except for subtraction tasks, in which they were less impaired than expected. Conclusions: DD and AS appear to be related to largely distinct patterns of cognitive deficits, which are present in combination in children with DD+AS.

Recent research has pointed to two possible causes of mathematical (dis-)ability: working memory and number sense, although only few studies have compared the relations between working memory and mathematics and between number sense and mathematics. In this study, both constructs were studied in relation to mathematics in general, and to mathematical learning disabilities (MLD) in particular. The sample consisted of 154 children aged between 6 and 10 years, including 26 children with MLD. Children performing low on either number sense or visual-spatial working memory scored lower on math tests than children without such a weakness. Children with a double weakness scored the lowest. These results confirm the important role of both visual-spatial working memory and number sense in mathematical development.

Abstract. The Monty Hall Dilemma (MHD) is an intriguing example of the discrepancy between people’s intuitions and normative reasoning. This study examines whether the notorious difficulty of the MHD is associated with limitations in working memory resources. Experiment 1 and 2 examined the link between MHD reasoning and working memory capacity. Experiment 3 tested the role of working memory experimentally by burdening the executive resources with a secondary task. Results showed that participants who solved the MHD correctly had a significantly higher working memory capacity than erroneous responders. Correct responding also decreased under secondary task load. Findings indicate that working memory capacity plays a key role in overcoming salient intuitions and selecting the correct switching response during MHD reasoning.
