Abstract
OBJECTIVE: This study sought to determine the validity of complexity and mystery as predictors of interior preferences and to identify design attributes related to their perception in interiors.
RESEARCH DESIGN: Preference ratings for 80 diverse interiors presented as black and white slides were provided by 321 college students. These were compared to ratings of two independent groups of students (n = 31 each) who sorted photographs of the scenes according to assessments of either complexity or mystery.
ANALYSIS: Quantitative relationships among complexity, mystery, and preference were described by Pearson's correlation coefficients. Design attributes related to perceptions of complexity and mystery were identified via visual content analyses of the environmental sample sequenced according to mean complexity and mystery ratings.
KEY FINDINGS: Complexity and mystery were positively related to preference (r= .8164 and r= .5832, p < .001, 1–tailed, respectively), and also to each other (r= .4195, p < .001, 1–tailed). Design characteristics underlying perceptions of complexity included the number and variety of elements present, the composition of scene elements, and the scene's spatial geometry. Perceptions of mystery were associated with scene accessibility, distance to the nearest point of interest, screening of view, degree of enclosure, and presence of dramatic brightness contrasts.
CONCLUSION: This study points to the utility of information models for explaining interior preferences and provides specific design direction for manipulating complexity and mystery within interior environments.
