The study of electrodermal activity (EDA) in individuals with Autism Spectrum Disorder (ASD) offers promising physiological biomarkers to enhance objective diagnosis. While previous research has explored responses to visual and auditory stimuli, the reaction to olfactory stimuli remains under-investigated. This research analyzed electrodermal responses to olfactory stimuli in the ASD population, examining its implications for tailoring educational strategies. A systematic review of literature from 2000 to 2024 was conducted using databases like Scopus and Web of Science, resulting in 20 relevant publications. Findings indicate that ASD individuals often exhibit distinct electrodermal patterns compared to the typically developing population, particularly with intense and emotionally provocative odors, which produce significant reactivity. EDA could thus serve as a valuable physiological indicator, aiding educators in adapting learning environments to the emotional needs of students with ASD, thereby optimizing the educational process.
