When imitating the behavior of an adult, children with the developmental disorder autism tend to skip "silly," unnecessary actions, while those without autism tend to copy everything they see, silly or not, a new study suggests.
Cognitive granularity: A new perspective over autistic and non-autistic styles of development - Kozima - 2013 - Japanese Psychological ResearchAbstract
It is widely suggested that ASD is characterized by atypical local/global processing, but the published findings are contradictory. In an effort to resolve this question, we tested a large group of children on both a free-choice task and an instructed task using hierarchical local–global stimuli. We find that although children with autism showed a reduced preference to report global properties of a stimulus when given a choice, their ability to process global properties when instructed to do so is unimpaired.
I'm sure that many people with an eye on the autism research scene will have come across the term 'gut-brain axis' at some point in their reading. Denoting the suggestion of a possible relationship between what goes on in our deepest, darkest recesses and brain function (and onwards observed behaviour) , the gut-brain axis has seemingly found a home particularly when looking at autism spectrum disorders.

Trends in Cognitive Sciences - Alternative Bayesian accounts of autistic perception: comment on Pellicano and BurrAtypical sensory-perceptual experiences are a widely acknowledged, but poorly understood feature of autism. An enduring and still unresolved question is whether autistic perception should best be characterized in terms of reduced top-down influences on perception or, alternatively, enhanced bottom-up sensory-perceptual processes [ 1 , 2 ]. In their recent Opinion article, Pellicano and Burr [ 3 ] argue for the former.
Is amygdala volume correlated with social network size or with special talents in autism spectrum disorders?
Bronchoscopic evaluations revealed that some children have double branching of bronchi (designated “doublets”) in the lower lungs airways, rather than normal, single branching. Retrospective analyses revealed only one commonality in them: all subjects with doublets also had autism or autism spectrum disorder (ASD).

Autistic spectrum disorders are complicated and most likely caused by a number of different problems. However, we still don’t know definitively if something in the diet could influence autism.
Individuals with autism spectrum disorders (ASD) demonstrate increased visual attention and elevated brain reward circuitry responses to images related to circumscribed interests (CI), suggesting that a heightened affective response to CI may underlie their disproportionate salience and reward value in ASD. To determine if individuals with ASD differ from typically developing (TD) adults in their subjective emotional experience of CI object images, non-CI object images and social images, 213 TD adults and 56 adults with ASD provided arousal ratings (sensation of being energized varying along a dimension from calm to excited) and valence ratings (emotionality varying along dimension of approach to withdrawal) for a series of 114 images derived from previous research on CI. The groups did not differ on arousal ratings for any image type, but ASD adults provided higher valence ratings than TD adults for CI-related images, and lower valence ratings for social images.
