abstract = {Individuals with autism spectrum disorder (ASD) often fail
to attach context to their memories and are specifically
impaired in processing social aspects of contextual
information. The aim of the present study was to investigate
the modulatory influence of social vs. non-social context on
neural mechanisms during encoding in ASD. Using
event-related fMRI, 13 boys with ASD and 13 typically
developing boys comparable for age and IQ were investigated
during encoding of neutral objects presented either with a
social (faces) or a non-social (houses) context. A memory
paradigm was then applied to identify brain activation
patterns associated with encoding of subsequently
recollected versus non-recollected objects. On the
behavioural level, no significant between-group differences
emerged. In particular, no differential effects of context
on memory performance were observed. Neurally, however,
context-specific group differences were observed in several
brain regions. During encoding of subsequently recollected
objects presented with a face, ASD subjects (compared to
controls) showed reduced neural activation in the bilateral
inferior frontal gyrus, bilateral middle frontal gyrus and
right inferior parietal lobule. Neural activation in the
right inferior frontal gyrus was positively correlated with
memory performance in controls, but negatively in ASD
individuals. During encoding of subsequently non-recollected
objects presented in the non-social context, ASD subjects
showed increased activation in the dorsal MPFC. Our findings
suggest that in ASD subjects, fronto-parietal brain regions
subserving memory formation and the association of
contextual information are activated atypically when a
social context is presented at encoding. The data add to
findings from related research fields indicating that in
ASD, socioemotional impairment extends into domains beyond
social cognition. Increased activation in the dorsal MPFC in
ASD individuals might reflect supervisory cognitive
processes related to the suppression of a distracting
non-social context.},
