No full textWe studied episodic memory and future thinking for self-relevant and other-relevant events at different levels of retrieval support, theory of mind, and delay discounting in ASD children and adolescents (ASDs). Compared to typically developing controls, ASDs produced fewer internal (episodic) but a similar number of external (semantic) details while remembering past events, imagining future events, and imagining future events happening to others, indicating a general impairment of event construction. This deficit was driven by group differences under high retrieval support, and therefore unlikely to depend on self-initiated retrieval/construction deficits. ASDs' event construction impairment related to the severity of ASD symptoms, and to theory of mind deficits. ASDs, however, showed normal delay discounting, highlighting preserved forms of future-based decision-making in ASD

Neural correlates of texture and contour integration in children with autism spectrum disorders
No full textIn this study, we have used an electrophysiological paradigm to investigate the
neural correlates of the visual integration of local signals across space to
generate global percepts in a group of low functioning autistic kids. We have
analyzed the amplitude of key harmonics of the Visual Evoked Potentials (VEPs)
recorded while participants observed orientation-based texture and contour
stimuli, forming coherent global patterns, alternating with visual patterns in
which the same number of local elements were randomly oriented in order to loose
any globally organized feature. Comparing the results of the clinical sample with
those obtained in an age-matched control group, we have observed that in the
texture conditions the 1st and 3rd harmonics, containing signature of global form
processing (Norcia, Pei, Bonneh, Hou, Sampath, & Pettet, 2005), were present in
the control group, while in the experimental group only the 1st harmonic was
present. In the Contour condition the 1st harmonic was not present for both
groups while the 3rd harmonic was significantly present in the control group but
absent in the group with autism. Moreover, the amount of organization required to
elicit significant 1st harmonic response in the texture condition was higher in
the clinical group. The present results bring additional support to the idea that
texture and contour processing are supported by independent mechanisms in normal
vision. Autistic vision would thus be characterized by a preserved, perhaps
weaker texture mechanism, possibly mediated by feedback interactions between
visual areas, and by a disfunction of the mechanism supporting contour
processing, possibly mediated by long-range intra-cortical connections. Within
this framework, the residual ability to detect contours shown in psychophysical
studies could be due to the contribution of the texture mechanism to contour
processing
