The role of cognitive and visual abilities as predictors in the Multifactorial Model of Driving Safety

摘要: OBJECTIVE: The current study evaluated part of the Multifactorial Model Driving Safety to elucidate relative importance cognitive function and a limited range standard measures visual in relation Capacity Drive Safely. Safely was operationalized using three validated screening for older drivers. These included an adaptation well Useful Field View (UFOV) two newer measures, namely Hazard Perception Test (HPT), Change Detection Task (HCDT). METHOD: Community dwelling drivers (n=297) aged 65-96 were assessed battery function. RESULTS: Factor analysis these predictor variables yielded factors including Executive/Speed, Vision (measured by acuity contrast sensitivity), Spatial, Visual Closure, Working Memory. Cognitive explained 83-95% age-related variance Spatial Memory associated with UFOV, HPT HCDT, Executive/Speed UFOV HCDT HPT. CONCLUSION: declines chronological age, this decline is several higher order abilities involving manipulation storage visuospatial information under speeded conditions. There are also age-independent effects vision that determine driving safety. Language: en
