| Abstract | IN PRESS with BRAIN INJURY – Please do not distribute or duplicate. When Directions Fail 2 Structured Abstract Primary Objective: Investigate and describe getting lost behaviour and wayfinding strategies among acquired brain injury (ABI) survivors and matched controls. Research Design: Matched control group comparison design Methods & Procedures: We compared wayfinding performance of 18 adults with acquired brain injury to controls matched for gender, age, and education. Participants followed written directions along an eight-step route in an unfamiliar neighborhood, with three intentionally challenging choice-points. They used a cellular phone to request assistance if they became lost. Dependent measures included accuracy, directness, and wayfinding strategy. Statistical and qualitative analyses explored group themes and differences. Main Results: Participants with ABI demonstrated significantly greater on-route wayfinding errors and hesitancy than matched controls. The ABI group requested assistance over the cell phone more frequently than controls and required more attempts at reorientation with concrete, salient directions in order to reorient in the field. Participants in the control group anticipated errors with greater frequency than those with ABI. Conclusions: ABI survivors demonstrated greater challenges with wayfinding than matched controls. Reorientation required concrete, explicit redirection with reference to salient landmarks. Implications for clinical practice and assistive technology are discussed. When Directions Fail 3 Introduction The ability to navigate one's community is a critical component of successful community reintegration following brain injury [1,2]. Cognitive, physical, and sensory impairments often limit a person's ability to drive [3,4,5], use public transportation [6], or travel on foot [7]. Navigation can be conceptualized as a spatial problem solving process that requires awareness, decision making, planning, and ongoing monitoring for error detection and correction [8,9]. These processes represent common areas of impairment for survivors of traumatic brain injury, and disrupt community navigation, or wayfinding. Wayfinding & Cognitive Impairments Navigation among individuals with cognitive impairments has been the subject of many investigations in the past decade. A growing body of neuropsychological literature has investigated the relation between specific navigational sub-skills and lesion site [10,11]. More specifically, researchers have attempted to describe spatial representation and navigation impairments associated with neglect syndrome [12,13]. Wayfinding difficulties have also been investigated in people with cognitive impairments due to progressive illnesses such as Alzheimer's disease in an attempt to identify the types of wayfinding problems and the associated cognitive correlates [9,14,15]. It has been suggested that spatial disorientation and wayfinding problems may be a sensitive indicator of the … |
