Abstract

Preference for architectural interiors can be explained using three psychological dimensions: Coherence (ease for organizing and comprehending a scene), Fascination (a scene's informational richness and generated interest), and Hominess (how much a space feels personal). We tested the hypothesis that their contributions to preference might vary based on individual differences by analyzing data from design students, participants with autism spectrum disorder, and neurotypical controls who rated images of interiors on liking and approach-avoidance decisions. For design students, only Coherence drove choices, whereas in participants with autism spectrum disorder and neurotypical controls Hominess and Fascination also contributed, respectively. Coherence is paramount for design students because it references the structural organization of spaces, and is informed by formal training. For autism spectrum disorder, Hominess matters because preference for familiarity, physical proximity, and difficulty in mental simulation are relevant to that population, whereas interest in visual exploration can explain Fascination's role in neurotypical controls.
