Introduction
Visual motion perception has gained some interest during the past few years. Recently a study in the UK among the deaf population showed that deaf adults who use British Sign Language (BLS) had faster reaction times and increased sensitivity to their peripheral vision compared to hearing adults and BLS interpreters (Codina et al,2017, p.1). This increase in the peripheral vison can be attributed to the theory of compensation in which the decline of one sensory system causes an increase in another sensory system (p.2). In the case of the deaf population auditory deprivation makes a demand of the visual system especially when learning a visuospatial language such as BLS or American Sign Language (ASL). Studies have shown that peripheral …show more content…

Because of these findings, it can be guessed that individuals with Autism spectrum disorder (ASD) may show greater peripheral sensitivity than deaf or hearing groups. A study in adolescents with ASD was conducted by Elizabeth Milne, Alison scope, Helen Griffiths, Charlotte Codina and David Buckley to test the sensitivity of peripheral vision in ASD and the study concluded that the participates with ASD detected less light flash stimulus in the nasal hemifield than the temporal hemifield than the control participants …show more content…

This study is socially relevant because it can be beneficial in any field that requires visual field response such as in sports and driving. It is especially socially relevant among school age children in assisting to detect danger. The unsolved problem that this study will address is whether Autistic children who are known to avoid eye contact even with perfect vision have faster reaction times than deaf individuals. This research study became of interest while the researcher came across an article stating that peripheral vision among the deaf population was better than in the hearing population. Because of the assumption that deaf individual need direct focus on a target to receive and send information the findings seem impossible. With studies supporting that deaf adults have faster and reaction and response time than other groups it is predicted that children who avoid eye contact, such as Autistic children should have faster reaction times than the deaf population since their central focus is not used when
