Cognitive control and conflict adaptation in youth with high-functioning autism / Michael J. LARSON in Journal of Child Psychology and Psychiatry, 53-4 (April 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-4 (April 2012) . - p.440-448 Titre : Cognitive control and conflict adaptation in youth with high-functioning autism Type de document : Texte imprimé et/ou numérique Auteurs : Michael J. LARSON, Auteur ; Mikle SOUTH, Auteur ; Peter E. CLAYSON, Auteur ; Ann CLAWSON, Auteur Année de publication : 2012 Article en page(s) : p.440-448 Langues : Anglais (eng) Mots-clés : N2  event-related potential  autism  conflict adaptation  cognitive control Index. décimale : PER Périodiques Résumé : Background:  Youth diagnosed with autism spectrum disorders (ASD) often show deficits in cognitive control processes, potentially contributing to characteristic difficulties monitoring and regulating behavior. Modification of performance following conflict can be measured by examining conflict adaptation, the adjustment of cognitive resources based on previous-trial conflict. The electrophysiological correlates of these processes can be measured using the N2, a stimulus-locked component of the event-related potential (ERP). Methods:  High-density ERPs and behavioral data [i.e. response times (RTs) and error rates] were acquired while 28 youth with ASD and 36 typically developing controls completed a modified Eriksen flanker task. Results:  Behaviorally, groups showed similar conflict adaptation effects; youth with ASD showed larger RT slowing on switch trials. For electrophysiology, controls demonstrated larger N2 amplitudes for incongruent (high-conflict) trials following congruent (low-conflict) trials than for incongruent trials following incongruent trials. Importantly, youth with ASD showed no such differences in N2 amplitude based on previous-trial conflict. Conclusions:  Lack of electrophysiological conflict adaptation effects in youth with ASD indicates irregular neural processing associated with conflict adaptation. Individuals with ASD show declines in level of conflict evaluation and adaptation. Future research is necessary to accurately characterize and understand the behavioral implications of these cognitive control deficits relative to diagnostic severity, anxiety, and personality.

Cognitive Control of Intentions for Voluntary Actions in Individuals With a High Level of Autistic Traits / Edita POLJAC in Journal of Autism and Developmental Disorders, 42-12 (December 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-12 (December 2012) . - p.2523-2533 Titre : Cognitive Control of Intentions for Voluntary Actions in Individuals With a High Level of Autistic Traits Type de document : Texte imprimé et/ou numérique Auteurs : Edita POLJAC, Auteur ; Ervin POLJAC, Auteur ; Nick YEUNG, Auteur Article en page(s) : p.2523-2533 Langues : Anglais (eng) Mots-clés : Autism  Autism-Spectrum Quotient  Cognitive control  Perseveration  Repetitive behavior  Voluntary task switching Index. décimale : PER Périodiques Résumé : Impairments in cognitive control generating deviant adaptive cognition have been proposed to account for the strong preference for repetitive behavior in autism. We examined if this preference reflects intentional deficits rather than problems in task execution in the broader autism phenotype using the Autism-Spectrum Quotient (AQ). Participants chose between two tasks differing in their relative strength by indicating first their voluntary task choice and then responding to the subsequently presented stimulus. We observed a stronger repetition bias for the harder task in high AQ participants, with no other differences between the two groups. These findings indicate that the interference between competing tasks significantly contributes to repetitive behavior in autism by modulating the formation of task intentions when choosing tasks voluntarily.

Cognitive control processes in behavior therapy for youth with Tourette's disorder / J. F. MCGUIRE in Journal of Child Psychology and Psychiatry, 63-3 (March 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-3 (March 2022) . - p.296-304 Titre : Cognitive control processes in behavior therapy for youth with Tourette's disorder Type de document : Texte imprimé et/ou numérique Auteurs : J.

PIACENTINI, Auteur Article en page(s) : p.296-304 Langues : Anglais (eng) Mots-clés : Cognitive control  behavior therapy  inhibition  inhibitory control  tic suppression Index. décimale : PER Périodiques Résumé : BACKGROUND: Cognitive control processes are implicated in the behavioral treatment of Tourette's disorder (TD). However, the influence of these processes on treatment outcomes has received minimal attention. This study examined whether cognitive control processes and/or tic suppression predicted reductions in tic severity and treatment response to behavior therapy. METHOD: Fifty-three youth with TD or a pervasive tic disorder participated in a randomized wait list-controlled trial of behavior therapy. Following a baseline assessment to evaluate psychiatric diagnoses, tic severity, and cognitive control processes (e.g., response selection, inhibition, and suppression), youth were randomly assigned to receive eight sessions of behavior therapy (n?=?23) or a wait list of equal duration (n?=?28). Youth receiving immediate treatment completed a post-treatment assessment to determine improvement in tic severity. Meanwhile, youth in the wait list condition completed another assessment to re-evaluate tic severity and cognitive control processes, and subsequently received 8 sessions of behavior therapy followed by a post-treatment assessment to determine improvement. RESULTS: A multiple linear regression model found that pretreatment inhibition/switching on the Delis-Kaplan Executive Function System Color-Word Interference Test predicted reductions in tic severity after behavior therapy (??=?-.36, t?=?-2.35, p?=?.025, ?(2) ?=?.15). However, other cognitive control processes and tic suppression did not predict treatment response and/or reductions in tic severity. Small nonsignificant effects were observed in cognitive control processes after behavior therapy. CONCLUSION: Cognitive control processes may influence tic severity reductions in behavior therapy. Notably, even when other cognitive control processes are impaired and youth are initially unable to voluntarily suppress their tics, youth with TD can still benefit from behavior therapy. Findings offer implications for clinical practice and research for TD.

Reduced Efficiency and Capacity of Cognitive Control in Autism Spectrum Disorder / Melissa-Ann MACKIE in Autism Research, 9-3 (March 2016)  

Public ISBD [article]  inAutism Research > 9-3 (March 2016) . - p.403-414 Titre : Reduced Efficiency and Capacity of Cognitive Control in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Melissa-Ann MACKIE, Auteur ; Jin FAN, Auteur Article en page(s) : p.403-414 Langues : Anglais (eng) Mots-clés : autism  cognitive control  information processing  information theory  executive functions Index. décimale : PER Périodiques Résumé : Cognitive control constrains mental operations to prioritize information that reaches conscious awareness and is essential to flexible, adaptive behavior under conditions of uncertainty. Cognitive control can be compromised by neurodevelopmental disorders such as autism spectrum disorder (ASD), which is characterized by the presence of social and communicative deficits, and restricted interests/repetitive behaviors. Although prior investigations have attempted to elucidate the nature of cognitive control in ASD, whether there is an underlying information processing deficit associated with cognitive control remains unclear. This study challenged cognitive control in 15 high-functioning adults with ASD and 15 typically developing (TD) controls using three novel tasks designed to systematically manipulate uncertainty. We aimed to investigate the efficiency of cognitive control in sequential information processing, cognitive control of nonsequential information processing across a range of cognitive loads and cognitive control capacity under time constraint. Results demonstrated that the ASD group performed less efficiently on sequential and nonsequential information processing, and had reduced cognitive control capacity under time constraint relative to the TD group. These findings suggest that inefficient cognitive control of information processing may be a fundamental deficit in ASD.

Bidirectional links between adolescent brain function and substance use moderated by cognitive control / Jungmeen KIM-SPOON in Journal of Child Psychology and Psychiatry, 62-4 (April 2021)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-4 (April 2021) . - p.427-436 Titre : Bidirectional links between adolescent brain function and substance use moderated by cognitive control Type de document : Texte imprimé et/ou numérique Auteurs : Jungmeen KIM-SPOON, Auteur ; Toria HERD, Auteur ; Alexis BRIEANT, Auteur ; Kristin M.

BICKEL, Auteur ; Brooks KING-CASAS, Auteur Article en page(s) : p.427-436 Langues : Anglais (eng) Mots-clés : Neural risk processing  cognitive control  functional neuroimaging  insula activation  neurotoxic effects  substance use Index. décimale : PER Périodiques Résumé : BACKGROUND: No clear consensus exists as to whether neurodevelopmental abnormalities among substance users reflect predisposing neural risk factors, neurotoxic effects of substances, or both. Using a longitudinal design, we examined developmental patterns of the bidirectional links between neural mechanisms and substance use throughout adolescence. METHOD: 167 adolescents (aged 13-14 years at Time 1, 53% male) were assessed annually four times. Risk-related neural processing was assessed by blood-oxygen-level-dependent responses in the insula during a lottery choice task, cognitive control by behavioral performance during the Multi-Source Interference Task, and substance use by adolescents' self-reported cigarette, alcohol, and marijuana use. RESULTS: Latent change score modeling indicated that greater substance use predicted increased insula activation during risk processing, but the effects of insula activation on changes in substance use were not significant. The coupling effect from substance use to insula activation was particularly strong for adolescents with low cognitive control, which supports the theorized moderating role of cognitive control. CONCLUSIONS: Our results elucidate how substance use may alter brain development to be biased toward maladaptive decision-making, particularly among adolescents with poor cognitive control. Furthermore, the current findings underscore that cognitive control may be an important target in the prevention and treatment of adolescent substance use given its moderating role in the neuroadaptive effects of substance use on brain development.
