The Effects Of Domain Knowledge And Scene Content On Change Detection Using A Change Blindness Paradigm, Marianne T. Baskin Dec 2007

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 Jul 2007

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 …


Gender Differences In Auditory Perception Of Pure Tone Frequencies And Speech Intelligibility Via Bone Conduction Transducers, Meghan Leigh Hodges Apr 2007

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 …
