The Effects Of Viewpoint, Motion, And Affordance Priming On Perceptual Learning Of Feelies, Catherine Dowell
The Effects Of Viewpoint, Motion, And Affordance Priming On Perceptual Learning Of Feelies, Catherine Dowell
Dissertations
According to Gibson and Gibson (1955) perceptual learning is a process of developing the skill to differentiate previously undifferentiated but available information. The initial investigations focused on object identification, lacking a behaviorally relevant functional task. In the current study participants learned to differentiate between novel objects (feelies). To test the role of visual exploration objects were viewed from either a side or a top view and were displayed as either static pictures or rotating about a vertical axis. In Experiment 1 a simple object discrimination task was used. Perfect accuracy was achieved sooner in static conditions compared to motion conditions …
Does Optic Flow Provide Information About Actions?, Hannah Masoner
Does Optic Flow Provide Information About Actions?, Hannah Masoner
Dissertations
Optic flow, the pattern of light generated in the visual field by motion of objects and the observer’s body, serves as information that underwrites perception of events, actions and affordances. This visual pattern informs the observer about their own actions in relation to their surroundings, as well as those of others. This study explored the limits of action detection for others as well as the role of optic flow. First-person videos were created using camera recordings of the actor’s perspective as they performed various movements (jumping jacks, jumping, squatting, sitting, etc.). In three experiments participants attempted to detect the action …

How Well Do You Know Your Reach?, Tyler Surber
How Well Do You Know Your Reach?, Tyler Surber
Dissertations
How does the relationship between an actor’s body proportions (eye-, shoulder-, and arm length) and environmental properties (object distance) affect the perception of whether an object is within reach? Experiment 1 demonstrated that participants are more accurate at judging their own eye height than shoulder height. Experiment 2 revealed that participants can accurately perceive the angular direction to a target object’s location. Interestingly, their pointing errors were significantly smaller when measured from the shoulder as a reference point than from the eye. In Experiment 3 we verified this finding using a functionally meaningful affordance task of reaching to a target …
Perceived Ideal Traits Of A Mentor As Viewed By African American Students In Science, Technology, Engineering, And Mathematics, Mary L. Smith
Perceived Ideal Traits Of A Mentor As Viewed By African American Students In Science, Technology, Engineering, And Mathematics, Mary L. Smith
Dissertations
The purpose of this study was to examine undergraduate students majoring in science, technology, engineering, and math disciplines perception of traits an ideal mentor should possess, and to determine if these traits had positive results on their identification with science. With a large number of workers in STEM disciplines retiring, there is a projected need for more underrepresented minorities to fill these positions. In order to increase diversity in the workforce, efforts must be made to retain underrepresented minorities in STEM education beginning at the undergraduate level and continuing throughout the graduate level. This intervention should begin as early as …
The Perception Of Distance On A Real Geographic Slope, David Alan Bunch
The Perception Of Distance On A Real Geographic Slope, David Alan Bunch
Dissertations
Ooi, Wu, and He (2001) have shown that for objects resting on flat, horizontal surfaces, those that appear in the lower sector of the visual field are perceived as close to the observer and objects located near the visual horizon are perceived as further from the observer. Researchers have hypothesized that observers utilize the angle subtended between the horizon and the line of sight to the target object as information for distance.In a previous investigation Hajnal, Bunch, and Kelty-Stephen (2014) showed that an object’s physical angle of declination below the horizon is not uniquely utilized when making distance estimates to …
Making Meaning Of The Reel: The Media's Portrayal Of Community Colleges, Jena Lee Hawk
Making Meaning Of The Reel: The Media's Portrayal Of Community Colleges, Jena Lee Hawk
Dissertations
Due to its seemingly unclear and ambiguous mission, the community college has somewhat of a stigma attached to it as a four-year institution defines the American college experience (LaPaglia, 1994). Although only a few studies concerning media portrayals of community college students have been published within the last twenty years, the existing studies (Bourke, Major, & Harris, 2009; LaPaglia, 1994; Tucciarone, 2007) have failed to address if the media’s portrayal of community colleges influences students’ decisions or actions with regard to enrolling in a two-year institution. Using the theoretical framework of critical media literacy, the researcher will examine if media …
Principal Leadership Styles, Faculty Morale, And Faculty Job Satisfaction At Selected Elementary Schools, Dawn Vyola Ramsey Hearn
Principal Leadership Styles, Faculty Morale, And Faculty Job Satisfaction At Selected Elementary Schools, Dawn Vyola Ramsey Hearn
Dissertations
The purpose of this study was to determine if a significant relationship existed between principal leadership styles, faculty morale, and faculty job satisfaction at selected elementary schools. Specifically, the study examined if the perception teachers had of their principals‟ leadership styles had an impact on faculty morale and faculty job satisfaction of teachers in Kindergarten through sixth grade at selected elementary schools in one school district located on the Mississippi Gulf Coast. The Leadership Practices Inventory (LPI) provided data that identified the perceived leadership styles of the school principals. The Purdue Teacher Opinionnaire (PTO) provided data that identified faculty morale …

Ecological Psychology And Media Consumption Among Young Adults: A New Framework, Alice Diana Cade Ferguson
Ecological Psychology And Media Consumption Among Young Adults: A New Framework, Alice Diana Cade Ferguson
Dissertations
The Pew Research Center (2010, March 1) identified three crucial “new metrics of news” (p. 2) that help to explain the appeal of new, interactive media forms among young adult news consumers. These metrics of Portability, Personalizability and Participation (Pew, 2010) highlight the rapid transformations in technology and user interests that have helped create a new manifestation of what McLuhan called an “age of anxiety” (1967/2001, pp. 8-9) in mass media industries and in mass communication education and scholarship. The purpose of this research is to investigate this very shift in how news is delivered and consumed, with particular attention …
The Effect Of Asian Origin, Culture And Learning Beliefs On High School Students' Physical Science Learning Beliefs, Xiaolan Li
Dissertations
Asian Americans have been recognized as the model minority in the United States since the 1960s. Students from Asian countries are winning in international competitions, especially in science and mathematics. Modern Western scholars working within the constructivist learning theory advocate malleable intelligence and effort, which actually corresponds to Asian learning beliefs and learning behaviors. This research is designed to test if American high school students and Chinese students from the mainland of China who are motivated to attend American universities are different in their learning beliefs of physical science and what accounts for the difference if there is any.
The Effect Of Teachers’ Expectations And Perceptions On Student Achievement In Reading For Third And Fifth Grade Students, Alfreda Ragland Williams
The Effect Of Teachers’ Expectations And Perceptions On Student Achievement In Reading For Third And Fifth Grade Students, Alfreda Ragland Williams
Dissertations
All too often, a student’s lack of success is blamed on his or her background, and/or the parent or the parent’s educational level. Many factors such as socioeconomic conditions, student behaviors, attendance, and teacher demographics can directly or indirectly affect class environment, classroom management, interaction with students, and equal treatment of students. In addition, a teacher’s perception of students plays a vital role in the teacher’s expectations, interactions, and relationships with his or her students. The purpose of the study was twofold. First, this study investigated the relationship between teachers’ expectations of equal treatment of students, class environment, interaction with …

What Influences Principal Perceptions Of Bullying?, Matthew Benjamin Alred
Dissertations
Bullying is a wide-spread problem that affects millions of students every day. School bullying is a serious social issue that can have both short-term and long-term devastating effects on the victims, bullies, and bystanders. Federal, state, and local agencies have created policies to address school bullying. However, the school principal has the most pivotal role in reducing the incidents of bullying and appropriately intervening in incidents that do occur. Furthermore, the principal is the most empowered by his or her role to bring about change to the school’s climate and culture which are key factors in the prevalence of bullying. …
