Bilingualism May Be Protective Against Executive Function and Visual Processing Deficits Among Children With Attention Problems.

Objective: The current study examined how the opposing effects of bilingualism and attention problems operate on executive functioning, visual processing, and verbal fluency in children with clinically significant levels of attention problems. Method: We tested whether bilingualism moderated associations between attention problems and visual processing, executive functioning, and verbal fluency. Results: Bilingual children (n = 331) showed visual processing advantages relative to their monolingual peers (n = 165), but only at higher, and not lower, levels of attention problems. Bilingualism did not moderate the association between attention problems and interference control; however, across all children, those with higher levels of attention problems had more difficulty with interference control. Monolingual children demonstrated advantages in verbal fluency relative to bilingual children, but this did not vary with attention problems. Conclusion: Visual processing advantages in bilinguals are detected among children with heightened attention problems, but advantages in interference control are not; findings may have implications for classroom interventions.

Phonological memory problems are magnified in children from language minority homes when predicting reading disability.

Children from language minority (LM) environments speak a language at home that differs from that at school, are often from socioeconomically disadvantaged backgrounds, and are at risk for reading impairment. We evaluated the main effects and interaction of language status and phonological memory and awareness on reading disorder in 352 children from socioeconomically disadvantaged backgrounds. A significant phonological memory by language status interaction indicated that phonological memory problems were magnified in predicting reading impairment in children from LM versus English dominant (ED) homes. Among children without reading disorder, language minority status was unrelated to phonological processing.

Pilot physical activity intervention reduces severity of ADHD symptoms in young children.

OBJECTIVE: Physical activity associates with mental health and neurocognitive function, showing potential for addressing ADHD symptoms. As a preliminary assessment of this potential, the authors piloted a before-school physical activity intervention for young children. METHOD: Seventeen children (Grades K-3) exhibiting four or more hyperactivity/impulsivity symptoms on the Disruptive Behavior Disorders Rating Scale (Pelham, 2002) completed about 26 min of continuous moderate-to-vigorous physical activity daily over eight school weeks. The authors administered cognitive, motor, social, and behavioral functioning measures at pre- and postprogram, assessed response inhibition weekly, and coded negative behaviors daily. RESULTS: Several measures showed significant or marginally significant change over time (effect size = 0.35-0.96) with additional measures showing meaningful effect size values (≥ 0.20). Response inhibition effects were most consistent. Most participants (64% to 71%) exhibited overall improvement according to postprogram parent, teacher, and program staff ratings. CONCLUSION: Physical activity shows promise for addressing ADHD symptoms in young children.

Does a positive bias relate to social behavior in children with ADHD?

This study examines whether positively biased self-perceptions relate to social behaviors in children with attention-deficit/hyperactivity disorder (ADHD) as compared to control children. The social behaviors of children with ADHD (n=87) were examined relative to control children (CTL; n=38) during a laboratory-based dyadic social interaction task. Children with ADHD were subgrouped into those with a positive illusory bias (PIB) in their self-perceptions (ADHD + PIB) versus those without such a bias (ADHD - PIB). Using a behavioral coding system adapted for this study, ADHD + PIB, ADHD - PIB, and CTL participants were compared on objectively coded social behaviors occurring within the context of the social interaction task. Whereas both ADHD groups displayed more disruptive behavior than controls, only the ADHD + PIB group displayed less prosocial behavior and less effortful behavior. This study breaks new ground by examining positively biased self-perceptions as they relate to social behavior in children with ADHD and provides promising new insight into the social problems experienced by these children.

Cognitive deficits and positively biased self-perceptions in children with ADHD.

This study examined the relation between cognitive deficits and positive bias in a sample of 272 children with and without Attention Deficit Hyperactivity Disorder (ADHD; 7-12 years old). Results indicated that children with ADHD with and without biased self-perceptions exhibit differences in specific cognitive deficits (executive processes, working memory, broad attention, and cognitive fluency) compared to each other and to control children. Further, specific cognitive deficits emerged as partial mediators of the relation between ADHD diagnostic status and positive bias. Interestingly, some differences in results emerged based on the domain considered (academic, social, behavioral competence). Results lend initial support to the role of cognitive deficits in the positive bias of some children with ADHD. Implications for future research and intervention are discussed.
