Autism spectrum disorder refers to a broad spectrum of neurodevelopmental disorders characterized by impairments in social interaction and communication that begin at a young age, which commonly exhibits repetitive behaviors and restricted interests (Xiao et al., 2014). This pervasive developmental disorder is more prevalent in males than in females and has recently gained more attention because of its rapid increase in prevalence (Xiao et al., 2014). Today, it is estimated that 69.5 per 10,000 people are on the autism spectrum (Kim, Chae-Seok, & Bong-Kiun, 2016). Autism spectrum disorder is also comorbid with many other disorders including intellectual disabilities (Kim et al., 2016). In a study consisting of 50 toddlers with autism spectrum disorder, brain structure was examines particularly looking at white matter. This study look at the comparison of children with autism spectrum disorder and children with developmental delays (Xiao et al., 2014). It was found that children with autism spectrum disorder have a larger volume of white matter, or myelinated axons, than children with a developmental delay. This was consistent with previous findings that used children without any type of disability as their control (Xiao et al., 2014). The study also found that grey matter volume in the child with autism spectrum disorder was “localized in the right superior temporal gyrus of the temporal lobe,” which is where the primary auditory cortex is found as well as Wernicke’s…
