Abstract: Atypical visual processing in children with
autism spectrum disorder (ASD) does not seem to reside in
an isolated processing component, such as global or local
processing.We therefore developed a paradigm that requires
the interaction between different processes—an identification
task with Gaborized object outlines—and applied this to
two age groups of 6-to-10 and 10-to-14 year old children
with and without ASD. Event history analyses demonstrated
an identification disadvantage in the ASD group, which
remained quite stable during the temporal unfolding of the
outline. The typically developing group particularly
outperformed the ASD group when more complex contours
were shown. Together, our results suggest that the interplay
between local and global processes and between bottom-up
and top-down processes is disturbed in ASD.
