Autism spectrum disorder (ASD) is a neurodevelopmental disorder in which the most prominent symptoms are deficits in social interaction and communication, and restricted and repetitive patterns of behavior, interests, or activities. The latest version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013) has recently included atypical sensory responsiveness (i.e., hyper- or hyporeactivity to sensory input). This review discusses attentional hypotheses and sensory processing as a developmental bias to stimulation processing in social interactions in individuals with ASD. The first section reviews the weak central coherence hypothesis (Happé & Frith, 2006) and reviews the enhanced perceptual functioning hypothesis (Mottron et al., 2006), which is a basic, but not necessarily social, disturbance of the perceptual-cognitive style and focuses on detail-focused processing in ASD. These proposed hypotheses are a framework within which the perceptual characteristics of individuals with ASD can be understood. The second section discusses a possible mechanism between specific sensory processing (e.g., arousal system and interoception) and atypical social interaction (e.g., repetitive and stereotyped interests and behaviors) in ASD, based on the discussion of the predictive coding theory. Individuals with ASD limit the input of information by an attentional focus on a part of the stimulus and/or by restricted and repetitive behavior. These aspects of information processing may contribute to the generation and stabilization of models of the internal or emotional self. Thus, attentional biases such as detail-focused processing in ASD are an adaptive mechanism for managing the overabundance of visual information.
"Astral Body" is an art installation for viewers to reveal the origin of life by showing the sense of life. A dead body and an artificial sign of life with dead matter are presented so that the viewers could think of relationship of the two. Astral Body has a kinetic surface made with ferromagnetic powder to present creature-like movements and human interaction. We have expressed the movements by using an automatic running robot with a magnet. Through the exhibitions, we have collected reactions and opinions from the attendees, and observed them. In this paper, we will conclude the overview, concept, design, implementation, and outcomes from the exhibitions.
