Effects of familiarity and plan complexity on wayfinding in simulated buildings

Abstract

While numerous studies have investigated the relationship between environmental familiarity and spatial cognition, no research has systematically examined the effects of familiarity on wayfinding performance. This experiment used a 5 × 5 factorial design to investigate the effects of floor plan complexity and degree of familiarity on spatial cognition and wayfinding. Subjects received five trials within one of five computer-simulated environments representing a range of plan complexity. Wayfinding performance data was collected during each trial. After all trials were completed, environmental knowledge was assessed through a sketchmap task. MANOVAs showed that wayfinding performance significantly decreased as a function of plan complexity. Plan complexity also significantly influenced sketchmap accuracy. Trend analysis showed a significant linear trend for wayfinding errors, which decreased with experience. This analysis also revealed a signficant interaction between plan complexity and experience on wayfinding. The findings suggest that environmental complexity has less of an impact on wayfinding as familiarity increases.
