Early institutionalized care disrupts the development of emotion processing in prosody / Lisa K. CHINN in Development and Psychopathology, 33-2 (May 2021)
[article]
Titre : Early institutionalized care disrupts the development of emotion processing in prosody Type de document : Texte imprimé et/ou numérique Auteurs : Lisa K. CHINN, Auteur ; Irina OVCHINNIKOVA, Auteur ; Anastasia A. SUKMANOVA, Auteur ; Aleksandra O. DAVYDOVA, Auteur ; Elena L. GRIGORENKO, Auteur Année de publication : 2021 Article en page(s) : p.421-430 Langues : Anglais (eng) Mots-clés : Eeg ERPs emotion recognition institutionalized care prosody Index. décimale : PER Périodiques Résumé : Millions of children worldwide are raised in institutionalized settings. Unfortunately, institutionalized rearing is often characterized by psychosocial deprivation, leading to difficulties in numerous social, emotional, physical, and cognitive skills. One such skill is the ability to recognize emotional facial expressions. Children with a history of institutional rearing tend to be worse at recognizing emotions in facial expressions than their peers, and this deficit likely affects social interactions. However, emotional information is also conveyed vocally, and neither prosodic information processing nor the cross-modal integration of facial and prosodic emotional expressions have been investigated in these children to date. We recorded electroencephalograms (EEG) while 47 children under institutionalized care (IC) (n = 24) or biological family care (BFC) (n = 23) viewed angry, happy, or neutral facial expressions while listening to pseudowords with angry, happy, or neutral prosody. The results indicate that 20- to 40-month-olds living in IC have event-related potentials (ERPs) over midfrontal brain regions that are less sensitive to incongruent facial and prosodic emotions relative to children under BFC, and that their brain responses to prosody are less lateralized. Children under IC also showed midfrontal ERP differences in processing of angry prosody, indicating that institutionalized rearing may specifically affect the processing of anger.

Titre : Electrophysiological alterations in motor-auditory predictive coding in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : T. VAN LAARHOVEN, Auteur ; J. J. STEKELENBURG, Auteur ; Mljm EUSSEN, Auteur ; J. VROOMEN, Auteur Article en page(s) : p.589-599 Langues : Anglais (eng) Mots-clés : ERPs autism spectrum disorder motor-auditory predictive coding Index. décimale : PER Périodiques Résumé : The amplitude of the auditory N1 component of the event-related potential (ERP) is typically attenuated for self-initiated sounds, compared to sounds with identical acoustic and temporal features that are triggered externally. This effect has been ascribed to internal forward models predicting the sensory consequences of one's own motor actions. The predictive coding account of autistic symptomatology states that individuals with autism spectrum disorder (ASD) have difficulties anticipating upcoming sensory stimulation due to a decreased ability to infer the probabilistic structure of their environment. Without precise internal forward prediction models to rely on, perception in ASD could be less affected by prior expectations and more driven by sensory input. Following this reasoning, one would expect diminished attenuation of the auditory N1 due to self-initiation in individuals with ASD. Here, we tested this hypothesis by comparing the neural response to self- versus externally-initiated tones between a group of individuals with ASD and a group of age matched neurotypical controls. ERPs evoked by tones initiated via button-presses were compared with ERPs evoked by the same tones replayed at identical pace. Significant N1 attenuation effects were only found in the TD group. Self-initiation of the tones did not attenuate the auditory N1 in the ASD group, indicating that they may be unable to anticipate the auditory sensory consequences of their own motor actions. These results show that individuals with ASD have alterations in sensory attenuation of self-initiated sounds, and support the notion of impaired predictive coding as a core deficit underlying autistic symptomatology. Autism Res 2019, 12: 589-599. (c) 2019 The Authors. Autism Research published by International Society for Autism Research published by Wiley Periodicals, Inc. LAY SUMMARY: Many individuals with ASD experience difficulties in processing sensory information (for example, increased sensitivity to sound). Here we show that these difficulties may be related to an inability to anticipate upcoming sensory stimulation. Our findings contribute to a better understanding of the neural mechanisms underlying the different sensory perception experienced by individuals with ASD.

MAES, Auteur Article en page(s) : p.1050-1061 Langues : Anglais (eng) Mots-clés : Asd ERPs N2b P3 Sli SRT task implicit learning Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) and specific language impairment (SLI) are two neurodevelopmental disorders characterized by deficits in verbal and nonverbal communication skills. These skills are thought to develop largely through implicit-or automatic-learning mechanisms. The aim of the current paper was to investigate the role of implicit learning abilities in the atypical development of communication skills in ASD and SLI. In the current study, we investigated Response Times (RTs) and Event Related Potentials (ERPs) during implicit learning on a Serial Reaction Time (SRT) task in a group of typically developing (TD) children (n = 17), a group of autistic children (n = 16), and a group of children with SLI (n = 13). Findings suggest that learning in both ASD and SLI are similar to that in TD. However, electrophysiological findings suggest that autistic children seem to rely mainly on more automatic processes (as reflected by an N2b component), whereas the children with SLI seem to rely on more controlled processes (as reflected by a P3 component). The TD children appear to use a combination of both learning mechanisms. These findings suggest that clinical interventions should aim at compensating for an implicit learning deficit in children with SLI, but not in children with ASD. Future research should focus on developmental differences in implicit learning and related neural correlates in TD, ASD, and SLI. Autism Res 2018, 11: 1050-1061. (c) 2018 The Authors Autism Research published by International Society for Autism Research and Wiley Periodicals, Inc. LAY SUMMARY: Autism and Specific Language Impairment (SLI) are two disorders characterized by problems in social communication and language. Social communication and language are believed to be learned in an automatic way. This is called "implicit learning." We have found that implicit learning is intact in autism. However, in SLI there seems different brain activity during implicit learning. Maybe children with SLI learn differently, and maybe this different learning makes it more difficult for them to learn language.

Participants were randomly assigned to a computerized training program involving either faces or houses. Pre- and post-testing included standardized and experimental measures of behavior and event-related brain potentials (ERPs), as well as interviews after training. After training, all participants met behavioral criteria for expertise with the specific stimuli on which they received training. Scores on standardized measures improved after training for both groups, but only the face training group showed an increased face inversion effect behaviorally and electrophysiological changes to faces in the P100 component. These findings suggest that individuals with ASD can gain expertise in face processing through training.

We compared children with ASD, ADHD or ADHD+ASD and typically developing controls (CTRL) on behavioural and electrophysiological correlates of gaze cue and face processing. We measured effects of ASD, ADHD and their interaction on the EDAN, an ERP marker of orienting visual attention towards a spatially cued location and the N170, a right-hemisphere lateralised ERP linked to face processing. We identified atypical gaze cue and face processing in children with ASD and ADHD+ASD compared with the ADHD and CTRL groups. The findings indicate a neurobiological basis for the presence of comorbid ASD symptoms in ADHD. Further research using larger samples is needed.
