Reduced Proactive Control Processes Associated With Behavioral Response Inhibition Deficits in Autism Spectrum Disorder / Shannon E. KELLY in Autism Research, 14-2 (February 2021)
[article]
Titre : Reduced Proactive Control Processes Associated With Behavioral Response Inhibition Deficits in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Shannon E. KELLY, Auteur ; Lauren M. SCHMITT, Auteur ; John A. SWEENEY, Auteur ; Matthew W. MOSCONI, Auteur Article en page(s) : p.389-399 Langues : Anglais (eng) Mots-clés : autism spectrum disorder cognition eye movements inhibitory control proactive control Index. décimale : PER Périodiques Résumé : Impairments in inhibitory control are common in individuals with autism spectrum disorder (ASD) and associated with multiple clinical issues. Proactive (i.e., delaying response onset) and reactive control mechanisms (i.e., stopping quickly) contribute to successful inhibitory control in typically developing individuals and may be compromised in ASD. We assessed inhibitory control in 58 individuals with ASD and 63 typically developing controls aged 5-29?years using an oculomotor stop-signal task during which participants made rapid eye movements (i.e., saccades) toward peripheral targets (i.e., GO trials) or inhibited saccades (i.e., STOP trials). Individuals with ASD exhibited reduced ability to inhibit saccades, reduced reaction time slowing (GO RT slowing), and faster stop-signal reaction times (SSRT) compared to controls. Across participants, stopping accuracy was positively related to GO RT slowing, and increased age was associated with higher stopping accuracy and GO RT slowing. Our results indicate that failures to proactively delay prepotent responses in ASD underpin deficits of inhibitory control and may contribute to difficulties modifying their behavior according to changes in contextual demands. These findings implicate frontostriatal brain networks in inhibitory control and core symptoms of ASD. LAY SUMMARY: Difficulties stopping actions are common in individuals with autism spectrum disorder (ASD) and are related to repetitive behaviors. This study compared the ability to stop eye movements in individuals with ASD and healthy peers. We found that individuals with ASD were less able to stop eye movements and that this difficulty was related to a reduced ability to delay their eye movements before seeing the cue to stop, not their ability to react quickly to this cue.

Titre : Not So Automatic Imitation: Expectation of Incongruence Reduces Interference in Both Autism Spectrum Disorder and Typical Development Type de document : Texte imprimé et/ou numérique Auteurs : Andrew GORDON, Auteur ; Raphael GEDDERT, Auteur ; Jeremy HOGEVEEN, Auteur ; Marie K. KRUG, Auteur ; Sukhvinder OBHI, Auteur ; Marjorie SOLOMON, Auteur Article en page(s) : p.1310-1323 Langues : Anglais (eng) Mots-clés : Automatic imitation Cognitive control Imitation Proactive control Index. décimale : PER Périodiques Résumé : Research has observed evidence for both hypo-(supposedly due to a broken mirror neuron system) and hyper-(thought to be the result of deficits in adaptive control) imitation in autism spectrum disorder (ASD). This work sought to adjudicate between these findings using an automatic imitation (AI) paradigm with the novel manipulation of the need to engage adaptive control of imitation. Results demonstrated that ASD participants do not display a specific deficit in AI capability, are able to engage in proactive control of AI, and that relative to a well-matched effector condition, AI is not selectively associated with ASD symptom severity. These data cast doubt upon the notion of impairments in imitation or its control in ASD.
