Differences in the Efficiency of Pattern Encoding in Relation to Autistic-Like Traits: An Event-Related Potential Study / Junichi TAKAHASHI in Journal of Autism and Developmental Disorders, 44-11 (November 2014)
[article]
Titre : Differences in the Efficiency of Pattern Encoding in Relation to Autistic-Like Traits: An Event-Related Potential Study Type de document : Texte imprimé et/ou numérique Auteurs : Junichi TAKAHASHI, Auteur ; Daichi YASUNAGA, Auteur ; Jiro GYOBA, Auteur Article en page(s) : p.2895-2907 Langues : Anglais (eng) Mots-clés : Autism spectrum quotient Complexity Encoding efficiency Event-related potential Index. décimale : PER Périodiques Résumé : We examined the effects of complexity on the efficiency of pattern encoding in the general population differing on autism-spectrum quotient (AQ) scores. We compared brain activity (electroencephalography) during a same-different task for High and Low AQ groups. The task was composed of identical comparison and categorical comparison (CC) conditions that presented simple or complex patterns. In the CC condition, the Low AQ showed large P3b amplitudes with simple patterns than with complex patterns, whereas the High AQ showed the same amplitude levels for these patterns. These indicate that, similar to simple patterns, complex patterns are efficiently encoded in the High AQ. Moreover, the High AQ had no impairment in the global pattern encoding compared with the Low AQ.

Titre : The N170 event-related potential reflects delayed neural response to faces when visual attention is directed to the eyes in youths with ASD Type de document : Texte imprimé et/ou numérique Auteurs : T. C. PARKER, Auteur ; M. J. CROWLEY, Auteur ; A. J. NAPLES, Auteur ; M. J. ROLISON, Auteur ; J. WU, Auteur ; J. A. TRAPANI, Auteur ; J. C. MCPARTLAND, Auteur Article en page(s) : p.1347-1356 Langues : Anglais (eng) Mots-clés : Adolescent Autism Spectrum Disorder Brain Child Evoked Potentials Facial Recognition Humans Eeg N170 autism event-related potential face perception social neuroscience Index. décimale : PER Périodiques Résumé : Atypical neural response to faces is thought to contribute to social deficits in autism spectrum disorder (ASD). Compared to typically developing (TD) controls, individuals with ASD exhibit delayed brain responses to upright faces at a face-sensitive event-related potential (ERP), the N170. Given observed differences in patterns of visual attention to faces, it is not known whether slowed neural processing may simply reflect atypical looking to faces. The present study manipulated visual attention to facial features to examine whether directed attention to the eyes normalizes N170 latency in ASD. ERPs were recorded in 30 children and adolescents with ASD as well as 26 TD children and adolescents. Results replicated prior findings of shorter N170 latency to the eye region of the face in TD individuals. In contrast, those with ASD did not demonstrate modulation of N170 latency by point of regard to the face. Group differences in latency were most pronounced when attention was directed to the eyes. Results suggest that well-replicated findings of N170 delays in ASD do not simply reflect atypical patterns of visual engagement with experimental stimuli. These findings add to a body of evidence indicating that N170 delays are a promising marker of atypical neural response to social information in ASD. LAY SUMMARY: This study looks at how children's and adolescents' brains respond when looking at different parts of a face. Typically developing children and adolescents processed eyes faster than other parts of the face, whereas this pattern was not seen in ASD. Children and adolescents with ASD processed eyes more slowly than typically developing children. These findings suggest that observed inefficiencies in face processing in ASD are not simply reflective of failure to attend to the eyes.

Titre : Increased reaction time variability in attention-deficit hyperactivity disorder as a response-related phenomenon: evidence from single-trial event-related potentials Type de document : Texte imprimé et/ou numérique Auteurs : Christopher W. N. SAVILLE, Auteur ; Bernd FEIGE, Auteur ; Christian KLUCKERT, Auteur ; Stephan BENDER, Auteur ; Monica BISCALDI, Auteur ; Andrea BERGER, Auteur ; Christian FLEISCHHAKER, Auteur ; Klaus HENIGHAUSEN, Auteur ; Christoph KLEIN, Auteur Article en page(s) : p.801-813 Langues : Anglais (eng) Mots-clés : ADHD EEG reaction time working memory event-related potential Index. décimale : PER Périodiques Résumé : Background Increased intra-subject variability (ISV) in reaction times (RTs) is a promising endophenotype for attention-deficit hyperactivity disorder (ADHD) and among the most robust hallmarks of the disorder. ISV has been assumed to represent an attentional deficit, either reflecting lapses in attention or increased neural noise. Here, we use an innovative single-trial event-related potential approach to assess whether the increased ISV associated with ADHD is indeed attributable to attention, or whether it is related to response-related processing. Methods We measured electroencephalographic responses to working memory oddball tasks in patients with ADHD (N = 20, aged 11.3 ± 1.1) and healthy controls (N = 25, aged 11.7 ± 1.1), and analysed these data with a recently developed method of single-trial event-related potential analysis. Estimates of component latency variability were computed for the stimulus-locked and response-locked forms of the P3b and the lateralised readiness potential (LRP). Results ADHD patients showed significantly increased ISV in behavioural ISV. This increased ISV was paralleled by an increase in variability in response-locked event-related potential latencies, while variability in stimulus-locked latencies was equivalent between groups. This result held across the P3b and LRP. Latency of all components predicted RTs on a single-trial basis, confirming that all were relevant for speed of processing. Conclusions These data suggest that the increased ISV found in ADHD could be associated with response-end, rather than stimulus-end processes, in contrast to prevailing conceptions about the endophenotype. This mental chronometric approach may also be useful for exploring whether the existing lack of specificity of ISV to particular psychiatric conditions can be improved upon.

KOTOV, Auteur Article en page(s) : p.1162-1170 Langues : Anglais (eng) Mots-clés : Adolescence anxiety biomarkers event-related potential Index. décimale : PER Périodiques Résumé : OBJECTIVE: An increased neural response to making mistakes has emerged as a potential biomarker of anxiety across development. The error-related negativity (ERN) is an event-related potential elicited when people make mistakes on simple laboratory-based reaction time tasks that has been associated with risk for anxiety. This study examined whether the ERN prospectively predicted the first onset of generalized anxiety disorder (GAD) over 1.5 years in adolescent girls. METHODS: The sample included 457 girls between the ages of 13.5 and 15.5 years, with no history of GAD. At baseline, the ERN was measured using a flankers task. Psychiatric history of the adolescent and biological parent was assessed with diagnostic interviews, and the adolescent completed a self-report questionnaire regarding anxiety symptoms. Approximately 1.5 years later, adolescents completed the same interview. RESULTS: An increased neural response to errors at baseline predicted first-onset GAD over 1.5 years. The ERN was a significant predictor independent of other prominent risk factors, including baseline anxiety and depression symptoms and parental lifetime psychiatric history. Jointly the ERN and social anxiety symptoms provided the greatest power for predicting first-onset GAD. CONCLUSIONS: This study provides evidence for the utility of the ERN as a biomarker of risk for GAD during a key developmental period.

Our results replicated findings in TD individuals and demonstrate attenuated early old–new effects in ASD. Late posterior negativity was present in the ASD group, but was not specific to this time window.
