Executive Functions and Symptom Severity in an Italian Sample of Intellectually Able Preschoolers with Autism Spectrum Disorder / Giovanni VALERI in Journal of Autism and Developmental Disorders, 50-9 (September 2020)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 50-9 (September 2020) . - p.3207-3215 Titre : Executive Functions and Symptom Severity in an Italian Sample of Intellectually Able Preschoolers with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Giovanni VALERI, Auteur ; Laura CASULA, Auteur ; Eleonora NAPOLI, Auteur ; Paolo STIEVANO, Auteur ; Barbara TRIMARCO, Auteur ; Stefano VICARI, Auteur ; Teresa Gloria SCALISI, Auteur Article en page(s) : p.3207-3215 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Executive functions  Inhibition  Preschoolers  Shifting  Working memory Index. décimale : PER Périodiques Résumé : A novel battery (BAFE; Valeri et al. 2015) was used in order to assess three executive function (EF) abilities (working memory, inhibition and shifting) in a sample of 27 intellectually able preschoolers with autism spectrum disorder (ASD) compared with 27 typically developing children matched on age and nonverbal IQ. Differences in EF skills were analyzed in participants with distinct ASD symptom severity. Children with ASD performed worse than typical controls on both set-shifting and inhibition, but not on visuo-spatial working memory. Additionally, children with more severe ASD symptoms showed a worse performance on inhibition than children with milder symptoms. These results confirm the presence of EF deficits and highlight a link between ASD symptoms and EF impairments in preschool age.

Executive functions in girls with and without childhood ADHD: developmental trajectories and associations with symptom change / Meghan MILLER in Journal of Child Psychology and Psychiatry, 54-9 (September 2013)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 54-9 (September 2013) . - p.1005-1015 Titre : Executive functions in girls with and without childhood ADHD: developmental trajectories and associations with symptom change Type de document : Texte imprimé et/ou numérique Auteurs : Meghan MILLER, Auteur ; Fred LOYA, Auteur ; Stephen P.

We hypothesized that (a) EF trajectories would be similar in girls both with and without childhood ADHD, with the ADHD group showing greater impairment across time; and (b) changes in EF abilities would predict changes in ADHD symptoms across time, consistent with the theory that ADHD symptom reductions partially result from prefrontally mediated EF development. Method Latent growth curve models were used to evaluate development of sustained attention, response inhibition, working memory, and global EF abilities, and associations between EF trajectories and ADHD symptom trajectories. Results Girls with childhood-diagnosed ADHD showed greater improvement across development on measures of sustained attention and global EF, but similar rates of improvement on measures of working memory and response inhibition. Changes in the global EF measure predicted changes in both inattentive and hyperactive-impulsive symptoms across time, whereas changes in response inhibition predicted changes in hyperactive-impulsive symptoms; associations between changes in other EF variables and symptoms were not significant. Conclusions Findings suggest variability in patterns of EF improvement over time in females with ADHD histories and indicate that EF development may play a role in symptom change.

Executive functions in savant artists with autism / Laura CRANE in Research in Autism Spectrum Disorders, 5-2 (April-June 2011)

This study assessed three facets of executive ability (fluency, perseveration and monitoring) in savant artists with ASD, compared to non-talented adults with ASD or mild/moderate learning difficulties (MLD). Executive functions were assessed in and out of the savants’ domain of expertise: on design fluency and card sort tasks, respectively. The design fluency task suggested a sparing of executive abilities in the savant artists, relative to the non-talented ASD group; an effect not observed on the card sort task. The idea that islets of ability involve functions that are protected from more general cognitive deficits in ASD is explored.

An intranasal herbal medicine improves executive functions and activates the underlying neural network in children with autism / Agnes S. CHAN in Research in Autism Spectrum Disorders, 8-6 (June 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-6 (June 2014) . - p.681-691 Titre : An intranasal herbal medicine improves executive functions and activates the underlying neural network in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Agnes S.

In particular, it reduces clinical symptoms and immunological anomalies in children with autism spectrum disorders (ASD). The present study explored whether the herbal formula can improve executive functions and the associated neuroelectrophysiological activity in ASD. Thirty children with ASD were evenly assigned to receive a daily intranasal administration of the herbal formula or no treatment. Their executive functions, behavioral problems, and electroencephalographic activity during an executive control task were measured before and after six months of treatment with the herbal formula. After treatment, the experimental group showed significantly improved inhibitory control, mental flexibility, and planning, which coincided with an event-related elevation in the activity of their prefrontal and anterior cingulate cortices (regions that are critical for executive control of behaviors) as well as reduced daily dysexecutive behaviors. In contrast, the control group showed no significant changes in executive functions or neural system activity. These findings support the administration of the intranasal herbal medicine as a possible intervention for improving executive functions in ASD.

Chronic early trauma impairs emotion recognition and executive functions in youth; specifying biobehavioral precursors of risk and resilience / Shai MOTSAN in Development and Psychopathology, 34-4 (October 2022)  

Public ISBD [article]  inDevelopment and Psychopathology > 34-4 (October 2022) . - p.1339-1352 Titre : Chronic early trauma impairs emotion recognition and executive functions in youth; specifying biobehavioral precursors of risk and resilience Type de document : Texte imprimé et/ou numérique Auteurs : Shai MOTSAN, Auteur ; Karen YIRMIYA, Auteur ; Ruth FELDMAN, Auteur Article en page(s) : p.1339-1352 Langues : Anglais (eng) Mots-clés : Adolescent  Biomarkers  Child, Preschool  Emotions/physiology  Executive Function/physiology  Humans  Hydrocortisone  Respiratory Sinus Arrhythmia/physiology  Rsa  dyadic reciprocity  emotion recognition  executive functions  longitudinal studies  resilience  trauma Index. décimale : PER Périodiques Résumé : Exposure to chronic early trauma carries lasting effects on children's well-being and adaptation. Guided by models on resilience, we assessed the interplay of biological, emotional, cognitive, and relational factors in shaping two regulatory outcomes in trauma-exposed youth: emotion recognition (ER) and executive functions (EF). A unique war-exposed cohort was followed from early childhood to early adolescence. At preadolescence (11-13 years), ER and EF were assessed and respiratory sinus arrhythmia (RSA), biomarker of parasympathetic regulation, was quantified. Mother-child dyadic reciprocity, child's avoidance symptoms, and cortisol (CT) were measured in early childhood. Trauma-exposed youth displayed impaired ER and EF abilities. Conditional process analysis described two differential indirect paths leading from early trauma to regulatory outcomes. ER was mediated by avoidance symptoms in early childhood and modulated by cortisol, such that this path was evident only for preadolescents with high, but not low, CT. In comparison, EF was mediated by the degree of dyadic reciprocity experienced in early childhood and modulated by RSA, observed only among youth with lower RSA. Findings pinpoint trauma-related disruptions to key regulatory support systems in preadolescence as mediated by early-childhood relational, clinical, and physiological factors and highlight the need to specify biobehavioral precursors of resilience toward targeted early interventions.
