- Abstract
Research on spatial thinking needs reliable and valid measures of individual differences in skills.Visuospatial Perspective Taking (PT)—the ability to mentally maintain and transform spatialrelationships between objects within an environment—is one kind of spatial skill that isespecially relevant to navigation and building cognitive maps. However, the psychometricproperties of various PT tasks have yet to be examined. The present study examines three mainpsychometric properties of PT tasks: 1) the reliability of two tasks developed for children butadapted in difficulty level for use in adult populations, 2) item difficulty and discriminabilitywithin and between four tasks using item response theory, and 3) relation of scores with generalintelligence, working memory, and mental rotation. Results showed that two of the four PT taskshave promising psychometric properties for measuring a wide range of PT ability based on itemdifficulty, discriminability, and efficiency of a test information function.
