This study evaluated the effectiveness of the Familiarity and Spatial Cognitive Style Scale (FSCS) and a computerized navigation task (LBS) in assessing navigational abilities among 185 college students. The results demonstrated that the FSCS questionnaire's SOD subscale effectively predicted real-world navigation performance while identifying 5.4% of participants with potential developmental topographical disorientation (DTD). The LBS task revealed a higher prevalence of navigation difficulties (11.96%), with minimal overlap between the two assessment methods - only two cases were flagged by both tools. This discrepancy suggests these instruments measure distinct aspects of navigational ability, potentially indicating different DTD subtypes: one affecting memory-based navigation and another impairing perceptual skills. The study also found gender differences in specific tasks, with male participants showing better performance in survey knowledge and landmark ordering tasks. These findings support using FSCS as an initial screening tool while emphasizing the need for comprehensive, multi-method assessments to fully understand individual navigation challenges. The results contribute to developing a more nuanced DTD taxonomy and pave the way for targeted interventions based on specific deficit profiles.
