TLDR
The results suggest that individuals with ASD may be biased towards speeded rather than accurate responding, and further, that reduced engagement with visual information may impede responses to visual attentional cues.Abstract:
Visual attention is integral to social interaction and is a critical building block for development in other domains (e.g., language). Furthermore, atypical attention (especially joint attention) is one of the earliest markers of autism spectrum disorder (ASD). The current study assesses low-level visual attention and its relation to social attentional processing in youth with ASD and typically developing (TD) youth, aged 7 to 18 years. The findings indicate difficulty overriding incorrect attentional cues in ASD, particularly with non-social (arrow) cues relative to social (face) cues. The findings also show reduced competition in ASD from cues that remain on-screen. Furthermore, social attention, autism severity, and age were all predictors of competing cue processing. The results suggest that individuals with ASD may be biased towards speeded rather than accurate responding, and further, that reduced engagement with visual information may impede responses to visual attentional cues. Once attention is engaged, individuals with ASD appear to interpret directional cues as meaningful. These findings from a controlled, experimental paradigm were mirrored in results from an ecologically valid measure of social attention. Attentional difficulties may be exacerbated during the complex and dynamic experience of actual social interaction. Implications for intervention are discussed.read more

The locus coeruleus-norepinephrine system as pacemaker of attention - a developmental mechanism of derailed attentional function in autism spectrum disorder.
TL;DR: In children with ASD, aberrant attentional function through atypical LC–NE activity is proposed as developmental mechanism leading to reduced social attention as well as social interaction and communication impairments.

TL;DR: Children with ASD and those with WS presented with overlapping deficits in spontaneous visual engagement with the target of others’ attention and in sustained attention in social and non-social dimensions of attention.

Metacognition, Mindfulness and Robots for Autism Inclusion
TL;DR: This article highlights the detailed research took place between 2010 - present, while examining the impact of robots on autistic children through their interaction, use of art, programming, cooperative games and mindfulness training, to helping children develop the higher mental abilities needed, so that decision-making and problem-solving achieved in their daily life.

Autism Pathogenesis: The Superior Colliculus
TL;DR: It is postulates that the superior colliculus is the key structure for such changes for several reasons: it dominates visual behavior during the first months of life, it is ready at birth for complex visual tasks, and it has a significant influence on several hemispheric regions.

TL;DR: In the ASD group, the sensory processing difficulties predicted executive and cognitive dysfunctions in the specific domains of inhibitory control, auditory sustained attention, and short-term verbal memory, after controlling the possible effect of ASD severity.

Orienting of attention
TL;DR: This paper explores one aspect of cognition through the use of a simple model task in which human subjects are asked to commit attention to a position in visual space other than fixation by orienting a covert mechanism that seems sufficiently time locked to external events that its trajectory can be traced across the visual field in terms of momentary changes in the efficiency of detecting stimuli.

Autism Diagnostic Interview-Revised: a revised version of a diagnostic interview for caregivers of individuals with possible pervasive developmental disorders
TL;DR: The revised interview has been reorganized, shortened, modified to be appropriate for children with mental ages from about 18 months into adulthood and linked to ICD-10 and DSM-IV criteria.
