Investigating autonomic and subjective responses to social vs. nonsocial stimuli may help to reveal underlying mechanisms of these atypical responses. This study examined autonomic responses (skin conductance level and heart rate) and subjective responses to social vs. nonsocial pictures in 37 adolescents with an ASD and 36 typically developing (TD) adolescents. Thirty-six pictures from the International Affective Picture System were presented, divided into six categories based on social content (social vs. nonsocial) and pleasantness (pleasant, neutral, and unpleasant). Both in adolescents with ASD as well as TD adolescents, pictures with a social content resulted in higher skin conductance responses (SCRs) for pleasant and unpleasant pictures than for neutral pictures. No differences in SCRs were found for the three nonsocial picture categories. Unpleasant pictures, both with and without a social content, showed more heart rate deceleration than neutral pictures. Self-reported arousal ratings were influenced by the social and affective content of a picture. No differences were found between individuals with ASD and TD individuals in their autonomic and subjective responses to the picture categories. These results suggest that adolescents with ASD do not show atypical autonomic or subjective responses to pictures with and without a social content. These findings make it less likely that impairments in social information processing in individuals with ASD can be explained by atypical autonomic responses to social stimuli.

A prospective study of heart rate and externalising behaviours in young children / Bram DIERCKX in Journal of Child Psychology and Psychiatry, 55-4 (April 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-4 (April 2014) . - p.402-410 Titre : A prospective study of heart rate and externalising behaviours in young children Type de document : Texte imprimé et/ou numérique Auteurs : Bram DIERCKX, Auteur ; Rianne KOK, Auteur ; Joke H. M. TULEN, Auteur ; Vincent W.V. JADDOE, Auteur ; Albert HOFMAN, Auteur ; Frank C. VERHULST, Auteur ; Marian J. BAKERMANS-KRANENBURG, Auteur ; Marinus H. VAN IJZENDOORN, Auteur ; Henning TIEMEIER, Auteur Article en page(s) : p.402-410 Mots-clés : Child  heart rate  anxiety  externalising behaviour  parenting  compliance Index. décimale : PER Périodiques Résumé : Background Low heart rate predicts externalising and delinquent behaviour in adults, adolescents and school-age children. In younger children the evidence is less clear. Moreover, the specificity of the relation between the autonomic nervous system and different forms of externalising behaviour is uncertain. We investigated the longitudinal relation between resting mean heart rate and different externalising behaviours. Methods In 412 children of the Generation R Study, we measured resting mean heart rate at 14 months. At 3 years, child problem behaviour was assessed by the mother with the Child Behavior Checklist. In a gift delay task, we observed whether children were compliant and whether they lied about their noncompliance. The association of heart rate with behaviour was contrasted with the effect of harsh parenting. Results In our main analysis, we examined the association between heart rate and reported and observed child behaviour. For comparison, the association of heart rate with behaviour was contrasted with the effect of harsh parenting. Mean heart rate was positively associated with Anxious/Depressed scale scores (? = .1, 95% CI = 0.01; 0.2, p = .04), but not with Aggressive Behaviour (? = .02; 95% CI = ?0.1; 0.1, p = .8) nor Attention Problem scale scores (? = .08, 95% CI = ?0.3; 0.5, p = .8). We could not demonstrate an association between mean heart rate and noncompliance during the gift delay task (OR = 1.14, 95% CI = 0.9; 1.1, p = .2), but lower heart rate predicted higher odds of the child lying (OR = 0.56, 95% CI = 0.3; 0.9, p = .03). In contrast, harsh parenting was associated with mother-reported Aggressive Behaviour (? = .7, 95% CI = 0.4; 0.9, p .001) and Attention Problems (? = .2, 95% CI = 0.1; 0.3, p .001), but not with observed lying (OR = 1.03, 95% CI = 0.8; 1.4, p = .8). Conclusions Lower resting mean heart rate at age 14 months predicts low anxiety symptoms and higher odds of lying at age 3 years. Low resting mean heart rate may be less an indicator of early childhood aggression than of fearless behaviour.
