Influence Of Social Isolation During Prolonged Simulated Weightlessness By Hindlimb Unloading, Candice G.T. Tahimic, Amber M. Paul, Ann-Sofie Schreurs, Samantha M. Torres, Linda Rubinstein, Sonette Steczina

Publications

The hindlimb unloading (HU) model has been used extensively to simulate the cephalad fluid shift and musculoskeletal disuse observed in spaceflight with its application expanding to study immune, cardiovascular and central nervous system responses, among others. Most HU studies are performed with singly housed animals, although social isolation also can substantially impact behavior and physiology, and therefore may confound HU experimental results. Other HU variants that allow for paired housing have been developed although no systematic assessment has been made to understand the effects of social isolation on HU outcomes. Hence, we aimed to determine the contribution of social isolation …

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 …

When Red Lights Look Yellow, Joanne M. Wood, David A. Atchison, Alex Chaparro

Publications

Purpose. Red signals are typically used to signify danger. This study was conducted to investigate a situation identified by train drivers in which red signals appear yellow when viewed at long distances (∼900 m) through progressive-addition lenses.

Methods. A laboratory study was conducted to investigate the effects of defocus, target size, ambient illumination, and surround characteristics on the extent of the color misperception of train signals by nine visually normal participants. The data from the laboratory study were validated in a field study by measuring the amounts of defocus and the distances at which the misperception of the color of …

The Influence Of Warning Label Presentation In Memory Recognition Of Aging Adults, Brian J. Call

Master's Theses - Daytona Beach

Research indicates that hundreds of thousands of people are injured each year as a result of poor communication between medical personnel, warning label information, and consumers when taking over the counter or prescription medication. Typically, as adults age, they are increasingly responsible for remembering the hazards of taking medications. If inadequate information exists in memory in regards to side effects, dosage, and other warnings, the likelihood of improper usage will increase. Because aging adults typically have a reduction in cognitive resources, it was hypothesized that older adults would require the aid of additional warning information to assist in the retrieval …
