In this study, we investigated event-related brain potentials evoked by cues that triggered social versus monetary reward anticipation in children with autism. Children with autism showed attenuated P3 activity in response to cues associated with a timely reaction to obtain a reward, irrespective of reward type. We attribute this atypical P3 activity in response to reward cues as reflective of diminished motivated attention to reward signals, a possible contributor to reduced social motivation in autism. Thus, our findings suggest a general reward processing deficit rather than a specific social reward dysfunction in autism.

Group-based cognitive behavioural psychotherapy for children and adolescents with ASD: the randomized, multicentre, controlled SOSTA – net trial / Christine M. FREITAG in Journal of Child Psychology and Psychiatry, 57-5 (May 2016)

We report results of a large, confirmatory, multicentre randomized-controlled phase-III trial in children and adolescents studying the ASD specific, manualized group-based cognitive behavioural SOSTA-FRA approach. Methods High-functioning ASD individuals aged 8–19 years old were randomized to 12 sessions SOSTA-FRA or treatment as usual. Primary outcomes were change in total raw score of the parent-rated Social Responsiveness Scale (pSRS) between baseline (T2) and end of intervention (T4), and between T2 and 3 months after end of intervention (T5). Trial registration: ISRCTN94863788. Results Between 20/5/2010 and 14/2/2013, n = 320 ASD patients were screened, n = 228 patients were randomized, and N = 209 analysed. Mean pSRS difference between groups at T4 was ?6.5 (95% CI ?11.6 to – 1.4; p = .013), and at T5 ?6.4 (?11.5 to ?1.3, p = .015). Pre-treatment SRS and IQ were positively associated with stronger improvement at T4 and T5. Conclusions Short-term ASD-specific add-on group-based psychotherapy has shown postintervention efficacy with regard to parent-rated social responsiveness predominantly in male high-functioning children and adolescents with ASD. Future studies should implement blinded standardized observational measures of peer-related social interaction.

Intact mirror mechanisms for automatic facial emotions in children and adolescents with autism spectrum disorder / Martin SCHULTE-RUTHER in Autism Research, 10-2 (February 2017)  

Public ISBD [article]  inAutism Research > 10-2 (February 2017) . - p.298-310 Titre : Intact mirror mechanisms for automatic facial emotions in children and adolescents with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Martin SCHULTE-RUTHER, Auteur ; Ellen OTTE, Auteur ; Kübra ADIGÜZEL, Auteur ; Christine FIRK, Auteur ; Beate HERPERTZ-DAHLMANN, Auteur ; Iring KOCH, Auteur ; Kerstin KONRAD, Auteur Article en page(s) : p.298-310 Langues : Anglais (eng) Mots-clés : mirror neuron system  electromyography  imitation  autism  perception action compatibility  facial emotions Index. décimale : PER Périodiques Résumé : It has been suggested that an early deficit in the human mirror neuron system (MNS) is an important feature of autism. Recent findings related to simple hand and finger movements do not support a general dysfunction of the MNS in autism. Studies investigating facial actions (e.g., emotional expressions) have been more consistent, however, mostly relied on passive observation tasks. We used a new variant of a compatibility task for the assessment of automatic facial mimicry responses that allowed for simultaneous control of attention to facial stimuli. We used facial electromyography in 18 children and adolescents with Autism spectrum disorder (ASD) and 18 typically developing controls (TDCs). We observed a robust compatibility effect in ASD, that is, the execution of a facial expression was facilitated if a congruent facial expression was observed. Time course analysis of RT distributions and comparison to a classic compatibility task (symbolic Simon task) revealed that the facial compatibility effect appeared early and increased with time, suggesting fast and sustained activation of motor codes during observation of facial expressions. We observed a negative correlation of the compatibility effect with age across participants and in ASD, and a positive correlation between self-rated empathy and congruency for smiling faces in TDC but not in ASD. This pattern of results suggests that basic motor mimicry is intact in ASD, but is not associated with complex social cognitive abilities such as emotion understanding and empathy.
