Affective Modulation of the Startle Eyeblink and Postauricular Reflexes in Autism Spectrum Disorder / Gabriel S. DICHTER in Journal of Autism and Developmental Disorders, 40-7 (July 2010)

Affective reflex modulation in control participants replicated previous findings. The ASD group, however, showed anomalous reflex modulation patterns, despite similar self-report ratings of pictures. Specifically, the ASD group demonstrated exaggerated eyeblink responses to pleasant images and exaggerated postauricular responses to unpleasant images. Although ASD is often conceptualized in terms of specific deficits in affective responding in the social domain, the present results suggest a domain-general pattern of deficits in affective processing and that such deficits may arise at an early phase in the stream of information processing.

Late Positive Potential ERP Responses to Social and Nonsocial Stimuli in Youth with Autism Spectrum Disorder / Stephen D. BENNING in Journal of Autism and Developmental Disorders, 46-9 (September 2016)

Social stimuli were faces with positive expressions and nonsocial stimuli were related to common restricted interests in ASD (e.g., electronics, vehicles, etc.). The ASD group demonstrated relatively smaller LPP amplitude to social stimuli and relatively larger LPP amplitude to nonsocial stimuli. There were no group differences in subjective ratings of images, and there were no significant correlations between LPP amplitude and ASD symptom severity within the ASD group. LPP results suggest blunted motivational responses to social stimuli and heightened motivational responses to nonsocial stimuli in youth with ASD.

The onset of puberty: Effects on the psychophysiology of defensive and appetitive motivation / Karina M. QUEVEDO in Development and Psychopathology, 21-1 (January 2009)  

Public ISBD [article]  inDevelopment and Psychopathology > 21-1 (January 2009) . - p.27-45 Titre : The onset of puberty: Effects on the psychophysiology of defensive and appetitive motivation Type de document : Texte imprimé et/ou numérique Auteurs : Karina M. QUEVEDO, Auteur ; Megan R. GUNNAR, Auteur ; Ronald E. DAHL, Auteur ; Stephen D. BENNING, Auteur Année de publication : 2009 Article en page(s) : p.27-45 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We examined puberty-specific effects on affect-related behavior and on the psychophysiology of defensive and appetitive motivation while controlling for age. Adolescents (N = 94, ages = 12 and 13 years) viewed 75 pictures (International Affective Picture System: pleasant, neutral, and aversive) while listening to auditory probes. Startle response and postauricular (PA) reflex were collected as measures of defensive and appetitive motivation, respectively. Pubertal status and measures of anxiety/stress reaction and sensation/thrill seeking were obtained. Mid-/late pubertal adolescents showed enhanced startle amplitude across all picture valences. A Puberty × Valence interaction revealed that mid-/late pubertal adolescents showed appetitive potentiation of the PA, whereas pre-/early pubertal adolescents showed no modulation of the PA reflex. Mid-/late pubertal adolescents also scored significantly higher on measures of sensation/thrill seeking than did their pre-/early pubertal peers and puberty moderated the association between psychophysiology and behavioral measures, suggesting that it plays a role in reorganizing defensive and appetitive motivational systems.
