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)

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.

Unbroken mirror neurons in autism spectrum disorders / Yang-Teng FAN in Journal of Child Psychology and Psychiatry, 51-9 (September 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-9 (September 2010) . - p.981-988 Titre : Unbroken mirror neurons in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Yang-Teng FAN, Auteur ; Jean DECETY, Auteur ; Chia-Yen YANG, Auteur ; Ji-Lin LIU, Auteur ; Yawei CHENG, Auteur Année de publication : 2010 Article en page(s) : p.981-988 Langues : Anglais (eng) Mots-clés : Mirror-neurons autism-spectrum-disorders mu-suppression Index. décimale : PER Périodiques Résumé : Background:  The ‘broken mirror’ theory of autism, which proposes that a dysfunction of the human mirror neuron system (MNS) is responsible for the core social and cognitive deficits in individuals with autism spectrum disorders (ASD), has received considerable attention despite weak empirical evidence. Methods:  In this electroencephalographic study, we examined mu suppression, as an indicator of sensorimotor resonance, concurrent with oculomotor performance while individuals (n = 20) with ASD and control participants (n = 20) either executed hand actions or observed hand actions or a moving dot. No difference in visual attention between groups was found as indicated by fixation duration and normalized fixation number on the presented stimuli. Results:  The mu suppression over the sensorimotor cortex was significantly affected by experimental conditions, but not by group membership, nor by the interaction between groups and conditions. Individuals with ASD, similar to the controls, exhibited stronger mu suppression when watching hand actions relative to a moving dot. Notably, participants with ASD failed to imitate the observed actions while their mu suppression indicating the MNS activity was intact. In addition, the mu suppression during the observation of hand actions was positively associated with the communication competence of individuals with ASD. Conclusion:  Our study clearly challenges the broken mirror theory of autism. The functioning of the mirror neuron system might be preserved in individuals with ASD to a certain degree. Less mu suppression to action observation coupled with more communicational severity can reflect the symptom heterogeneity of ASD. Additional research needs to be done, and more caution should be used when reaching out to the media.
