Journal ArticleDOI
Is the early modulation of brain activity by fearful facial expressions primarily mediated by coarse low spatial frequency information
TL;DR: The findings clearly show that fearful facial expressions increases the amplitude of P1 and N170 in comparison to neutral faces but only in LSF faces, irrespective of contrast or luminance equalization, further suggesting that LSF information plays a crucial role in the early brain responses to fear.
Journal ArticleDOI
Atypical visual orienting to gaze- and arrow-cues in adults with high functioning autism.
TL;DR: In participants with autism the overall visual orienting reflex was not different between arrows and eyes and no laterality effect was found for eyes cueing, suggesting that persons with autism might have a general ‘Symbol Direction Detector’.
Journal ArticleDOI
Basic Abnormalities in Visual Processing Affect Face Processing at an Early Age in Autism Spectrum Disorder
Petra H. J. M. Vlamings,Lisa M. Jonkman,Emma van Daalen,Rutger Jan van der Gaag,Chantal Kemner +4 more
TL;DR: In this article, the authors investigated whether young ASD children show abnormalities in low spatial frequency (LSF, global) and high spatial frequency(HSF, detailed) processing and explored whether these are crucially involved in the early development of face processing.
Journal ArticleDOI
Reduced error monitoring in children with autism spectrum disorder: an ERP study
Petra H. J. M. Vlamings,Lisa M. Jonkman,Marco Hoeksma,Herman van Engeland,Chantal Kemner,Chantal Kemner +5 more
TL;DR: The reduced ERN in children with ASD, in the presence of an intact CRN, might suggest a specific insensitivity to detect situations in which the chance of making errors is enhanced and lead to reduced error awareness/attention allocation to the erroneous event.
Journal ArticleDOI
An eye for detail: an event-related potential study of the rapid processing of fearful facial expressions in children.
TL;DR: Developmental effects are discussed in terms of maturation of the fast subcortical face-processing route as well as an increase in experience with facial expressions with age.
