Working memory and autism: A review of literature / Suneeta KERCOOD in Research in Autism Spectrum Disorders, 8-10 (October 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-10 (October 2014) . - p.1316-1332 Titre : Working memory and autism: A review of literature Type de document : Texte imprimé et/ou numérique Auteurs : Suneeta KERCOOD, Auteur ; Janice A. GRSKOVIC, Auteur ; Devender R. BANDA, Auteur ; Jasmine BEGESKE, Auteur Article en page(s) : p.1316-1332 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Working memory  Auditory working memory  Visiospatial working memory Index. décimale : PER Périodiques Résumé : Research studies that evaluated working memory with students with autism and other disorders were reviewed and summarized. Results suggest that persons with autism score lower on measures of working memory than do typical controls especially on tasks that require cognitive flexibility, planning, greater working memory load, and spatial working memory, and with increasing task complexity and in dual task conditions. Lower scores in verbal working memory were associated with greater problems in adaptive behavior and more restrictive and repetitive behavior. Children with autism were as likely as typical children to employ articulatory rehearsal (verbal WM). The format of WM tasks may determine whether or not performance is impaired. Implications for educational practice and future research are discussed.

Working memory and cognitive flexibility-training for children with an autism spectrum disorder: a randomized controlled trial / Marieke DE VRIES in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-5 (May 2015) . - p.566-576 Titre : Working memory and cognitive flexibility-training for children with an autism spectrum disorder: a randomized controlled trial Type de document : Texte imprimé et/ou numérique Auteurs : Marieke DE VRIES, Auteur ; Pier J. M. PRINS, Auteur ; Ben A. SCHMAND, Auteur ; Hilde M. GEURTS, Auteur Article en page(s) : p.566-576 Langues : Anglais (eng) Mots-clés : Executive functioning  working memory  flexibility  cognitive training  autism Index. décimale : PER Périodiques Résumé : Background People with autism spectrum disorders (ASDs) experience executive function (EF) deficits. There is an urgent need for effective interventions, but in spite of the increasing research focus on computerized cognitive training, this has not been studied in ASD. Hence, we investigated two EF training conditions in children with ASD. Methods In a randomized controlled trial, children with ASD (n = 121, 8–12 years, IQ > 80) were randomly assigned to an adaptive working memory (WM) training, an adaptive cognitive flexibility-training, or a non-adaptive control training (mock-training). Braingame Brian, a computerized EF-training with game-elements, was used. Outcome measures (pretraining, post-training, and 6-week-follow-up) were near-transfer to trained EFs, far-transfer to other EFs (sustained attention and inhibition), and parent's ratings of daily life EFs, social behavior, attention deficit hyperactivity disorder (ADHD)-behavior, and quality of life. Results Attrition-rate was 26%. Children in all conditions who completed the training improved in WM, cognitive flexibility, attention, and on parent's ratings, but not in inhibition. There were no significant differential intervention effects, although children in the WM condition showed a trend toward improvement on near-transfer WM and ADHD-behavior, and children in the cognitive flexibility condition showed a trend toward improvement on near-transfer flexibility. Conclusion Although children in the WM condition tended to improve more in WM and ADHD-behavior, the lack of differential improvement on most outcome measures, the absence of a clear effect of the adaptive training compared to the mock-training, and the high attrition rate suggest that the training in its present form is probably not suitable for children with ASD.

Working memory and organizational skills problems in ADHD / Michael J. KOFLER in Journal of Child Psychology and Psychiatry, 59-1 (January 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-1 (January 2018) . - p.57-67 Titre : Working memory and organizational skills problems in ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Michael J.

SOTO, Auteur ; Nicole FERRETTI, Auteur Article en page(s) : p.57-67 Langues : Anglais (eng) Mots-clés : ADHD  working memory  organization  executive functions  functional impairments Index. décimale : PER Périodiques Résumé : Background This study tested model-driven predictions regarding working memory's role in the organizational problems associated with ADHD. Method Children aged 8–13 (M = 10.33, SD = 1.42) with and without ADHD (N = 103; 39 girls; 73% Caucasian/Non-Hispanic) were assessed on multiple, counterbalanced working memory tasks. Parents and teachers completed norm-referenced measures of organizational problems (Children's Organizational Skills Scale; COSS). Results Results confirmed large magnitude working memory deficits (d = 1.24) and organizational problems in ADHD (d = 0.85). Bias-corrected, bootstrapped conditional effects models linked impaired working memory with greater parent- and teacher-reported inattention, hyperactivity/impulsivity, and organizational problems. Working memory predicted organization problems across all parent and teacher COSS subscales (R2 = .19–.23). Approximately 38%–57% of working memory's effect on organization problems was conveyed by working memory's association with inattentive behavior. Unique effects of working memory remained significant for both parent- and teacher-reported task planning, as well as for teacher-reported memory/materials management and overall organization problems. Attention problems uniquely predicted worse organizational skills. Hyperactivity was unrelated to parent-reported organizational skills, but predicted better teacher-reported task planning. Conclusions Children with ADHD exhibit multisetting, broad-based organizational impairment. These impaired organizational skills are attributable in part to performance deficits secondary to working memory dysfunction, both directly and indirectly via working memory's role in regulating attention. Impaired working memory in ADHD renders it extraordinarily difficult for these children to consistently anticipate, plan, enact, and maintain goal-directed actions.

Working Memory Impairments in Chromosome 22q11.2 Deletion Syndrome: The Roles of Anxiety and Stress Physiology / Ashley F. P. SANDERS in Journal of Autism and Developmental Disorders, 47-4 (April 2017)

Broad memory deficits, anxiety, and elevated stress have been reported in individuals with chromosome 22q11.2 deletion syndrome (22q11.2DS). We investigated anxiety and physiological stress reactivity in relation to visuospatial working memory impairments in 20 children with 22q11.2DS and 32 typically developing (TD) children ages 7 to 16. Children with 22q11.2DS demonstrated poorer working memory, reduced post-stress respiratory sinus arrhythmia recovery, and overall increased levels of cortisol in comparison to TD children. Anxiety, but not physiological stress responsivity, mediated the relationship between 22q11.2DS diagnosis and visuospatial working memory impairment. Findings indicate that anxiety exacerbates impaired working memory in children with 22q11.2DS.

Working memory moderates the association between early institutional care and separation anxiety symptoms in late childhood and adolescence / Laura Alicia ALBA in Development and Psychopathology, 31-3 (August 2019)  

Public ISBD [article]  inDevelopment and Psychopathology > 31-3 (August 2019) . - p.989-997 Titre : Working memory moderates the association between early institutional care and separation anxiety symptoms in late childhood and adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Laura Alicia ALBA, Auteur ; Jessica FLANNERY, Auteur ; Mor SHAPIRO, Auteur ; Nim TOTTENHAM, Auteur Article en page(s) : p.989-997 Langues : Anglais (eng) Mots-clés : cortisol  early caregiving adversity  emotion dysregulation  separation anxiety  working memory Index. décimale : PER Périodiques Résumé : Adverse caregiving, for example, previous institutionalization (PI), is often associated with emotion dysregulation that increases anxiety risk. However, the concept of developmental multifinality predicts heterogeneity in anxiety outcomes. Despite this well-known heterogeneity, more work is needed to identify sources of this heterogeneity and how these sources interact with environmental risk to influence mental health. Here, working memory (WM) was examined during late childhood/adolescence as an intra-individual factor to mitigate the risk for separation anxiety, which is particularly susceptible to caregiving adversities. A modified “object-in-place” task was administered to 110 youths (10–17 years old), with or without a history of PI. The PI youths had elevated separation anxiety scores, which were anticorrelated with morning cortisol levels, yet there were no group differences in WM. PI youths showed significant heterogeneity in separation anxiety symptoms and morning cortisol levels, and WM moderated the link between caregiving and separation anxiety and mediated the association between separation anxiety and morning cortisol in PI youth. Findings suggest that (a) institutional care exerts divergent developmental consequences on separation anxiety versus WM, (b) WM interacts with adversity-related emotion dysregulation, and (c) WM may be a therapeutic target for separation anxiety following early caregiving adversity.
