Final answer:
Sarah, a four-year-old with autism, displays impaired social interaction and communication, as well as possibly other behaviors such as repetitive motor actions and adherence to rituals, indicative of Autism Spectrum Disorder (ASD) symptoms.
Step-by-step explanation:
Sarah, a four-year-old child with autism, exhibits characteristics commonly associated with Autism Spectrum Disorders (ASD). These include impaired social interaction and communication, which covers difficulties in making eye contact, reading social cues, and in some cases, feeling empathy for others. Children like Sarah might also engage in repetitive motor behaviors such as rocking back and forth, have a preoccupation with specific subjects, show a strict adherence to rituals, and use language in unusual ways.
ASD is a neurodevelopmental disorder with a wide range of symptoms and severities. Some children with ASD may have associated conditions like epilepsy or intellectual disabilities, while others have strong language skills and feel that their brains simply process information differently. Because ASD is a spectrum disorder, it presents differently in each individual, making it crucial to understand that even though Sarah might exhibit certain symptoms, her abilities and challenges are unique to her.
