Atypical mismatch negativity to distressful voices associated with conduct disorder symptoms / An-Yi HUNG 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.1016-1027 Titre : Atypical mismatch negativity to distressful voices associated with conduct disorder symptoms Type de document : Texte imprimé et/ou numérique Auteurs : An-Yi HUNG, Auteur ; Jyrki AHVENINEN, Auteur ; Yawei CHENG, Auteur Article en page(s) : p.1016-1027 Langues : Anglais (eng) Mots-clés : Conduct disorder (CD)  distressful voices  impulsivity  juvenile delinquents  mismatch negativity (MMN) Index. décimale : PER Périodiques Résumé : Background Although a general consensus holds that emotional reactivity in youth with conduct disorder (CD) symptoms arises as one of the main causes of successive aggression, it remains to be determined whether automatic emotional processing is altered in this population. Methods We measured auditory event-related potentials (ERP) in 20 young offenders and 20 controls, screened for DSM-IV criteria of CD and evaluated using the youth version of Hare Psychopathy Checklist (PCL:YV), State-Trait Anxiety Inventory (STAI) and Barrett Impulsiveness Scale (BIS-11). In an oddball design, sadly or fearfully spoken ‘deviant’ syllables were randomly presented within a train of emotionally neutral ‘standard’ syllables. Results In young offenders meeting with CD criteria, the ERP component mismatch negativity (MMN), presumed to reflect preattentive auditory change detection, was significantly stronger for fearful than sad syllables. No MMN differences for fearful versus sad syllables were observed in controls. Analyses of nonvocal deviants, matched spectrally with the fearful and sad sounds, supported our interpretation that the MMN abnormalities in juvenile offenders were related to the emotional content of sounds, instead of purely acoustic factors. Further, in the young offenders with CD symptoms, strong MMN amplitudes to fearful syllables were associated with high impulsive tendencies (PCL:YV, Factor 2). Higher trait and state anxiety, assessed by STAI, were positively correlated with P3a amplitudes to fearful and sad syllables, respectively. The differences in group-interaction MMN/P3a patterns to emotional syllables and nonvocal sounds could be speculated to suggest that there is a distinct processing route for preattentive processing of species-specific emotional information in human auditory cortices. Conclusions Our results suggest that youths with CD symptoms may process distressful voices in an atypical fashion already at the preattentive level. This auditory processing abnormality correlated with increased impulsivity and anxiety. Our results may help to shed light on the neural mechanisms of aggression.

Dissociation between affective sharing and emotion understanding in juvenile psychopaths / Yawei CHENG in Development and Psychopathology, 24-2 (May 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-2 (May 2012) . - p.623-636 Titre : Dissociation between affective sharing and emotion understanding in juvenile psychopaths Type de document : Texte imprimé et/ou numérique Auteurs : Yawei CHENG, Auteur ; An-Yi HUNG, Auteur ; Jean DECETY, Auteur Année de publication : 2012 Article en page(s) : p.623-636 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Empathy dysfunction is one of the core characteristics of youth with callous–unemotional (CU) traits. How such a dysfunction is associated with abnormal neural processing, however, remains to be determined. This study combined assessment of Hare Psychopathy Checklist Youth Version, pressure pain threshold, and event-related brain potentials elicited by the perception of people in pain in 15 young offenders with low CU traits (LCU), 13 with high CU traits (HCU), and 15 typically developing controls. Compared to the controls, LCU and HCU had higher pain thresholds. Although only the central late positive potential (LPP) was reduced in LCU, both the frontal N120 and central LPP were diminished in HCU. When exposed to situations in which someone was harmed by another, HCU retained the LPP, and this response was significantly correlated with their psychopathic traits and pain thresholds. Both groups had no deficit in sensorimotor resonance as assessed by mu suppression. These results demonstrate that youth with HCU exhibit atypical neural dynamics of pain empathy processing in the early stage of affective arousal, which is coupled with their relative insensitivity to actual pain. Their capacity to understand intentionality, however, was not affected. Such uncoupling between affective arousal and emotion understanding may contribute to instigating aggressive behaviors in juvenile psychopaths.

Linkage between pain sensitivity and empathic response in adolescents with autism spectrum conditions and conduct disorder symptoms / Chenyi CHEN in Autism Research, 10-2 (February 2017)  

Public ISBD [article]  inAutism Research > 10-2 (February 2017) . - p.267-275 Titre : Linkage between pain sensitivity and empathic response in adolescents with autism spectrum conditions and conduct disorder symptoms Type de document : Texte imprimé et/ou numérique Auteurs : Chenyi CHEN, Auteur ; An-Yi HUNG, Auteur ; Yang-Teng FAN, Auteur ; Shuai TAN, Auteur ; Hua HONG, Auteur ; Yawei CHENG, Auteur Article en page(s) : p.267-275 Langues : Anglais (eng) Mots-clés : pain sensitivity  empathy  autism spectrum conditions  conduct disorder symptom Index. décimale : PER Périodiques Résumé : Lack of empathy is one of the behavioral hallmarks in individuals with autism spectrum conditions (ASC) as well as youth with conduct disorder symptoms (CDS). Previous research has reliably documented considerable overlap between the perception of others' pain and first-hand experience of pain. However, the linkage between empathy for pain and sensitivity to physical pain needs to be empirically determined, particularly in individuals with empathy deficits. This study measured the pressure pain threshold, which indexes sensitization of peripheral nociceptors, and assessed subjective ratings of unpleasantness and pain intensity in response to empathy-eliciting stimuli depicting physical bodily injuries in three age- and sex-matched participant groups: ASC, CDS, and typically developing controls (TDC). The results indicated that the pain threshold was lowest in the ASC group and highest in the CDS group. The ASC group displayed lower ratings of unpleasantness and pain intensity than did the TDC and CDS groups. Within the ASC and CDS, pain intensity ratings were significantly correlated with unpleasantness ratings to others' pain. Moreover, the ASC significantly differed from the TDC in the correlation between pain threshold values and unpleasantness ratings. These findings may cast some light on the linkage between atypical low-level sensory functioning, for instance altered pain sensitivity, and high-level empathic processing.
