Effect Of Short-Storage Hrgcs On Driver Decision Behavior And Safety Concerns: Real-World Analysis And Experimental Evidence, Anne Linja
Dissertations, Master's Theses and Master's Reports
Vehicle-train collisions at highway-rail grade crossings (HRGCs) continue to be a safety concern, and despite improvements in warnings, many of these incidents are attributed to human error. In some cases, distractions other than railroad traffic, such as HRGCs with limited space between the railroad tracks and the highway intersection, may create additional cognitive burdens for drivers. We investigated the effect of HRGC type (short-storage vs. non-short storage) on driver attention and decision-making in two studies. In Study 1, we systematically analyzed 996 incidents from 2017-2019 from the Federal Railroad Administration’s Safety database. Driver decision making and outcomes were different depending …
Visual Search In Naturalistic Imagery, Dave Schreifels
Visual Search In Naturalistic Imagery, Dave Schreifels
Dissertations, Master's Theses and Master's Reports
Visual search has been extensively studied in the laboratory, yielding broad insights into how we search through and attend to the world around us. In order to know if these insights are valid, however, this research must not be confined to the sanitized imagery typically found within the lab. Comparatively little research has been conducted on visual search within naturalistic settings, and this gap must therefore be bridged in order to further our understanding of visual search. Based on the results of Experiment 1, Experiment 2 was conducted to test three common effects observed in previous studies of visual search: …
Designing Better Symbols: An Attentional Approach To Match Symbols To Performance Goals, Hannah North
Designing Better Symbols: An Attentional Approach To Match Symbols To Performance Goals, Hannah North
Dissertations, Master's Theses and Master's Reports
Effective displays require symbol sets that are customized to specific tasks and performance goals. In order to create such sets, designers must account for the effects of top-down and bottom-up attention. The current work presents a pair of experiments that examined the effects of salience and cueing in a change detection tasks within the flicker paradigm (Rensink, O’Regan and Clark, 1997). Each trial, participants either received no cue or a cue indicating which symbol would be the target. This cueing manipulation isolated top-down effects to the cued condition. Consistent with previous studies (Orchard, 2012; Steelman, Orchard, Fletcher, Cockshell, Williamson & …
