The Effects Of Domain Knowledge And Scene Content On Change Detection Using A Change Blindness Paradigm, Marianne T. Baskin
The Effects Of Domain Knowledge And Scene Content On Change Detection Using A Change Blindness Paradigm, Marianne T. Baskin
Master's Theses - Daytona Beach
This thesis was designed to determine how domain knowledge or scene content affects change detection. Twenty-four participants of medical professionals and non-medical professionals performed a change detection task using a flicker paradigm intended to be similar to saccadic movements or blinks. Each participant viewed 24 pictures on a computer screen, each picture flickering with a blank gray screen alternating between the original and modified version of the picture, and was asked to indicate when a change was detected by depressing a key. Twelve of the pictures were medical X-rays while the other 12 were everyday scenes. Reaction time, number of …
Quantifying The Cognitive, Symptomatic And Neuroendocrine Impact Of The Coriolis Illusion; A Countermeasure For Motion Sickness, Catherine Grandizio
Quantifying The Cognitive, Symptomatic And Neuroendocrine Impact Of The Coriolis Illusion; A Countermeasure For Motion Sickness, Catherine Grandizio
Master's Theses - Daytona Beach
When pilots are unable to accurately perceive the position and motion of their bodies, they are spatially disoriented. Spatial disorientation is often induced by aviation illusions, and its consequences include dizziness, confusion, nausea and fatigue. The present research evaluated the severity of cognitive, neuroendocrine and subjective symptoms of the Coriolis illusion, induced by a spatial disorientation flight training device. Also, the research examined the effectiveness of a mild, ground-based countermeasure, similar to the Coriolis illusion, in reducing the occurrence and severity of symptoms. In the early stages of data analysis, there appeared to be a significant impact of the Coriolis …
A Macroscopic Validation Of The Evacuation Simulation Prediction Tool On Highway Travel Times, Kay Fortinberry Borglum
A Macroscopic Validation Of The Evacuation Simulation Prediction Tool On Highway Travel Times, Kay Fortinberry Borglum
Master's Theses - Daytona Beach
The purpose of this applied research study was to test the sensitivity of the Evacuation Simulation Prediction (ESP) tool in predicting travel time during high volume traffic periods. The discrete event-based simulation tool was designed to aid local evacuation planning contingencies. Research of the Florida Department of Transportation traffic count data demonstrated parallel trends in rush hour volume versus hurricane evacuation volume. A model validation was designed to test if the model closely predicted high volume travel on a major interstate. For this macroscopic sensitivity test, volume, travel time and speed were collected to examine the baseline predictability under crash …
Gender Differences In Auditory Perception Of Pure Tone Frequencies And Speech Intelligibility Via Bone Conduction Transducers, Meghan Leigh Hodges
Gender Differences In Auditory Perception Of Pure Tone Frequencies And Speech Intelligibility Via Bone Conduction Transducers, Meghan Leigh Hodges
Master's Theses - Daytona Beach
Two experiments were conducted to see if gender differences exist in bone conduction hearing processes. The first experiment was a pure tone study where hearing thresholds for six pure tone frequencies and four bone conduction skull locations were measured in 15 male and 15 female participants to determine if gender differences exist in auditory signal detection. As frequency of the pure tone signal increased the difference between genders’ hearing thresholds and mean ranks of threshold overall; however, when Kruskal-Wallis statistical tests were performed, significant differences between genders for bone conduction were only found for the mastoid location at 6000-Hz and …
