This study explores the representation of characters with autism in classic and modern literature, examining how societal understanding and portrayals of autism have evolved over time. By analyzing key literary works, the research identifies recurring themes, narrative functions, and the depth of character development concerning autistic traits. The study contrasts early depictions-often marked by stereotypes or a lack of formal diagnosis-with contemporary portrayals that reflect greater awareness and nuanced representation. Additionally, the research investigates the impact of these depictions on public perception, inclusivity, and the broader literary landscape. Through this comparative approach, the study highlights shifts in narrative techniques, authorial intent, and cultural attitudes toward autism, contributing to ongoing discussions on neurodiversity in literature.
