Cross-syndrome comparison

A research methodology that evaluates a technology or intervention with participants from multiple disability groups to determine whether findings and design principles generalize across conditions. Cross-syndrome comparisons are important because assistive technologies designed for one population — such as autism spectrum disorder — are often assumed to work for others with similar support needs — such as intellectual disability — without explicit testing. Studies using this approach have revealed that design principles do not automatically transfer: populations with different cognitive profiles may need fundamentally different interaction modalities, prompting strategies, and support structures.
