Inattentional Deafness And Musical Training: Effects Of Perceptual Load On Tonal And Verbal Auditory Suppression, Annelise Coffey

All-Inclusive List of Electronic Theses and Dissertations

Inattentional deafness (ID) is a cognitive phenomenon of which we have relatively little understanding. The current study attempted to address this by considering current cognitive theories of thought and examined how musical training affects incidence rates of inattentional deafness. This study utilized a cognitive task and auditory stimuli previously designed to elicit inattentional deafness and measured musical training by administering the Goldsmith’s Musical Sophistication Index. Participants were instructed to engage in a high-load cognitive task, providing a condition in which inattentional deafness is likely to occur. During the task, a brief pure tone was presented simultaneously with the visual task …


A Study Of Quality Requirement Conveyance For Assignments In Technology And Engineering Master’S Degree Programs, Heather J. Mccain May 2020

A Study Of Quality Requirement Conveyance For Assignments In Technology And Engineering Master’S Degree Programs, Heather J. Mccain

All-Inclusive List of Electronic Theses and Dissertations

Quality requirements are not easy to define. In higher education, defining quality requirements and communicating those requirements to students may be accomplished through a variety of mechanisms. Students still may not know what it takes to get a good grade on an assignment and may have to wait for an instructor to clarify the assignment. This study was conducted because students and instructors may have different opinions as to which forms of feedforward and what technology are best to convey assignment requirements. The purpose of this study was to determine effective feedforward mechanisms as well as the technology used to …


The Effects Of Bioinspired Infill Designs And Density On The Compressive Strength Of Parts Produced By Additive Manufacturing Via Fused Deposition Modeling, Joseph D. Long May 2020

The Effects Of Bioinspired Infill Designs And Density On The Compressive Strength Of Parts Produced By Additive Manufacturing Via Fused Deposition Modeling, Joseph D. Long

All-Inclusive List of Electronic Theses and Dissertations

The current state of additive manufacturing (AM) is still primarily used for prototyping and modeling. However, with the increase in available materials and more advanced machines, AM is beginning to become a production process in which ready-to-ship products are being manufactured. This makes it all the more important to effectively and efficiently use the material in AM machines. One of the ways that material usage can be improved upon is more efficiently structuring the infill material that is used. This dissertation reports on the testing and statistical analysis of the compressive modulus of elasticity, the compressive proportional limit, and the …

Measuring The Effects Of An American Physiological Society’S Phun Week Activity On 2nd Grade Students, James Edelman May 2014

Measuring The Effects Of An American Physiological Society’S Phun Week Activity On 2nd Grade Students, James Edelman

All-Inclusive List of Electronic Theses and Dissertations

In the last few years the United States has been on the decline in the fields of science and technology. The American Physiological Society (APS) has developed a program to engage young minds with scientists. Physiology Understanding Week (PhUn) is the APS initiative to use interactive experiments to engage school-age children with science and physiology. Even though PhUn Week has been going on since 2005, systematic assessment of the activities effects is rare. Here, we sought to assess if an APS PhUn Week activity enhances physiology understanding and interest in science in second grade children form a rural area. The …


Factors Affecting The Probability Of Acoustic Detection And Site Occupancy Of Bats In Central Indiana, Zachary David Epping Kaiser May 2014

Factors Affecting The Probability Of Acoustic Detection And Site Occupancy Of Bats In Central Indiana, Zachary David Epping Kaiser

All-Inclusive List of Electronic Theses and Dissertations

Documenting the presence of rare bat species can be difficult. The current summer survey protocol for the federally endangered Indiana bat (Myotis sodalis) requires passive acoustic sampling with directional microphones (e.g., Anabats), but there are still questions about best practices for choosing survey sites and appropriate detector models. Indiana bats are capable of foraging in an array of cover types, including structurally-complex, interior forests. Further, data acquisition among different commercially available bat detectors is likely highly variable, due to the use of proprietary microphones with different frequency responses, sensitivities, and directionality. We paired omnidirectional Wildlife Acoustic SM2BAT+ (SM2) and directional …

Impacts Of Different Forest Tree-Harvest Methods On Diets And Populations Of Insectivorous Forest Bats, Megan K. Caylor Aug 2011

Impacts Of Different Forest Tree-Harvest Methods On Diets And Populations Of Insectivorous Forest Bats, Megan K. Caylor

All-Inclusive List of Electronic Theses and Dissertations

The Hardwood Ecosystem Experiment (HEE) in central Indiana presents an excellent opportunity to study species reactions to different forestry practices: clearcutting, shelterwood cutting, and single tree selections. This project focuses on the differences in the populations and diets of the various insectivorous bat species in the HEE management units. Bats studied were Myotis septentrionalis, Lasiurus borealis, Eptesicus fuscus, Perimyotis subflavus, Myotis sodalis, Myotis lucifugus, and Lasionycteris noctivagans. Since insectivorous bats do not simply eat whatever is available, and I hypothesize that the diets of these bats will not change despite their changing environment and changing populations. To test these ideas, …


The Status Of Crawfish Frogs (Lithobates Areolatus) In Indiana, And A Tool To Assess Populations, Nathan J. Engbrecht Dec 2010

The Status Of Crawfish Frogs (Lithobates Areolatus) In Indiana, And A Tool To Assess Populations, Nathan J. Engbrecht

All-Inclusive List of Electronic Theses and Dissertations

The conservation status of Crawfish Frogs (Lithobates areolatus) in Indiana has changed over the past several decades. Once described as being locally plentiful, declines led to the listing of Crawfish Frogs as a State Endangered Species in 1988. Several records for this species in Indiana are > 50 yrs old and have gone unconfirmed for several decades. However, recent surveys have confirmed the continued presence of Crawfish Frogs in parts of southern Indiana, redefining the perceived range of this species in the state. In an effort to increase survey efficiency in this species, I used automated recording systems and manual call …
