This simulation models the sensory-processing side of special education support: how ambient noise, lighting glare and an unpredictable routine combine into a sensory load, how that load is amplified by an individual's own sensitivity, and how the resulting arousal level drives task performance along a real inverted-U (Yerkes-Dodson) curve rather than a simple "more support is always better" line. Push the environment too far and sustained over-arousal accumulates into a genuine sensory-overload event with a visible performance collapse and recovery period — then use noise-canceling headphones, a visual schedule, or a scheduled sensory break to see exactly how each support pulls the student back toward their optimal zone, the same logic behind predictable-environment strategies used in real IEPs.
