The Effects Of Instructor-Avatar Immediacy In Second Life, An Immersive And Interactive 3d Virtual Environment, Sabine Karine Lawless-Reljic Edd

Dissertations

Growing interest of educational institutions in desktop 3D graphic virtual environments for hybrid and distance education prompts questions on the efficacy of such tools. Virtual worlds, such as Second Life®, enable computer-mediated immersion and interactions encompassing multimodal communication channels including audio, video, and text-. These are enriched by avatar-mediated body language and physical manipulation of the environment. In this para-physical world, instructors and students alike employ avatars to establish their social presence in a wide variety of curricular and extra-curricular contexts. As a proxy for the human body in synthetic 3D environments, an avatar represents a 'real' human computer user …

Teacher Perceptions Of Student Support Team And Response To Intervention, Lynn Russell Bailey

Doctoral Dissertations and Projects

The purpose of this study was to investigate teacher perceptions of Student Support Team (SST) and Response to Intervention (RTI) effectiveness. While an effective, researchbased framework is certainly paramount to the success of either endeavor, the teachers involved in the process and their perceptions directly impact the effectiveness. Teacher perceptions of their familiarity with SST and RTI, adequacy of training, qualifications to implement, the effectiveness of SST and RTI, eligibility requirements for special education, weaknesses of the frameworks, and reasons for non-referral are examined in the study. The sample population for the survey consisted of teachers (n=342) from around the …

The Unfixedness Of It, Kerry O'Grady

Masters Theses 1911 - February 2014

My drawings contemplate the unfixed nature of my experience. I draw from a state of uncertainty about the relationship between self and space, between a moment of experience and the one that follows it. My process involves intuitive mark-making in which instances of perception are indeterminate and discontinuous. I draw from the experience of unhinged moments, from silence and stillness, and from the indefinable, inarticulable, interstitial moments of perception between those that can be concretely described.

The immediacy of drawing, the direct engagement with the mark on the surface, is central to my work. Intuitive mark-making is a way of …

Principal And Teacher Perceptions Of Change Implementation Practices In 2007 And 2008 Small Learning Communities Grant Recipient, Benjamin Bristo

Electronic Theses and Dissertations

Leading through change is a difficult process. School leaders who hope to create meaningful, long-term change must be cognizant of numerous factors. This study was undertaken with the hope of increasing educational leaders' awareness of how their decisions are viewed by those who follow them. Case studies revealed pertinent data within two schools that have undertaken a significant change initiative. All 2007 and 2008 Small Learning Communities (SLC) grant-recipient schools in Florida were invited to participate in a series of case studies. Participating principals were questioned about their perceptions of how they fulfill their change leadership role related to the …

The Effect Of Word Sociality On Word Recognition, Sean Seaman

Wayne State University Dissertations

While research into the role of semantic structure in the recognition of written and spoken words has grown, it has not looked specifically at the role of conversational context on the recognition of isolated words. This study was a corpus-based and behavioral exploration of a new semantic variable - sociality - and used on-line behavioral testing to obtain new word recognition data using the visual and auditory lexical decision tasks. The results consistently demonstrated that sociality is one of the most robust predictors of lexical decision performance. Overall, it appears that the visual lexical decision task is quite sensitive to …

Phase-Linking And The Perceived Motion During Off-Vertical Axis Rotation, Jan E. Holly, Scott J. Wood, Gin Mccollum

Gin McCollum

Human off-vertical axis rotation (OVAR) in the dark typically produces perceived motion about a cone, the amplitude of which changes as a function of frequency. This perception is commonly attributed to the fact that both the OVAR and the conical motion have a gravity vector that rotates about the subject. Little-known, however, is that this rotating-gravity explanation for perceived conical motion is inconsistent with basic observations about self-motion perception: (a) that the perceived vertical moves toward alignment with the gravito-inertial acceleration (GIA) and (b) that perceived translation arises from perceived linear acceleration, as derived from the portion of the GIA …

The Perception Of Fairness Of Performance Appraisals, Tracy M. Prather

ETD Archive

The perception of fairness in performance appraisals (PA) is one of the most important factors and considered a criterion when reviewing PA effectiveness (Jacobs, Kafry, and Zedeck, 1980). In this particular study, I examined numerous variables in three main categories: interpersonal, procedural, and outcome fairness. Keep in mind that although these are three distinct categories, they are all inter-related. One hundred ninety-two employees, from the research and development section of a large retail company, voluntarily participated. The results were slightly contradictory to what was expected yet they were good results. The interpersonal variable, manager effectiveness, along with the outcome variables, …

Seeing Is Believing: Body Motion Dominates In Multisensory Conversations, Cathy Ennis, Rachel Mcdonnell, Carol O'Sullivan

Articles

In many scenes with human characters, interacting groups are an important factor for maintaining a sense of realism. However, little is known about what makes these characters appear realistic. In this paper, we investigate human sensitivity to audio mismatches (i.e., when individuals’ voices are not matched to their gestures) and visual desynchronization (i.e., when the body motions of the individuals in a group are mis-aligned in time) in virtual human conversers. Using motion capture data from a range of both polite conversations and arguments, we conduct a series of perceptual experiments and determine some factors that contribute to the plausibility …

Philosophy Of Intellect And Vision In The De Anima Of Themistius, John Shannon Hendrix

Architecture, Art, and Historic Preservation Faculty Publications

Themistius (317–c. 387) was born into an aristocratic family and ran a paripatetic school of philosophy in Constantinople in the mid-fourth century, between 345 and 355. He made use of Alexander’s De anima in his commentary on the De anima of Aristotle, which is considered to be the earliest surviving commentary on Aristotle’s work, as Alexander’s commentary itself did not survive. Themistius may also have been influenced by Plotinus, and Porphyry (232–309), whom he criticizes. Themistius refers often to works of Plato, especially the Timaeus, and attempts a synthesis of Aristotle and Plato, a synthesis which was continued in …

The Relationship Between The Perception Of Axes Of Symmetry And Spatial Memory During Early Childhood, Margaret R. Ortmann, Anne R. Schutte

Department of Psychology: Faculty Publications

Early in development, there is a transition in spatial working memory (SWM). When remembering a location in a homogeneous space (e.g., in a sandbox), young children are biased toward the midline symmetry axis of the space. Over development, a transition occurs that leads to older children being biased away from midline. The dynamic field theory (DFT) explains this transition in biases as being caused by a change in the precision of neural interaction in SWM and improvements in the perception of midline. According to the DFT, young children perceive midline, but there is a quantitative improvement in the perception of …

Sensor Data And Perception: Can Sensors Play 20 Questions, Cory Andrew Henson

Kno.e.sis Publications

Currently, there are many sensors collecting information about our environment, leading to an overwhelming number of observations that must be analyzed and explained in order to achieve situation awareness. As perceptual beings, we are also constantly inundated with sensory data, yet we are able to make sense of our environment with relative ease. Why is the task of perception so easy for us, and so hard for machines; and could this have anything to do with how we play the game 20 Questions?

The Civil Behavior Of Students: A Survey Of School Professionals, Keely Wilkins, Paul Caldarella, Rachel Crook-Lyon, K. Richard Young

Faculty Publications

Many authors regard education as a way of increasing civility in society, and some have implemented interventions to improve civility in schools. However, very little empirical data exist on the extent and nature of students' civil behavior. The present study systematically gathered data from 251 school professionals regarding their perceptions of students' civil and uncivil behaviors. Participants perceived students' civil behaviors as occurring more frequently than uncivil behaviors; however, they also indicated a need to increase civil behavior in schools. They provided suggestions on how to accomplish this goal, which include providing direct instruction, modeling civil behavior, incorporating positive behavior …

The Influence Of Action Learning On Student Perception And Performance, Brad Stappenbelt

Faculty of Engineering - Papers (Archive)

The study of floating oscillating water column (OWC) wave energy conversion (WEC) device performance includes analysis of the dynamic coupling of the water column and the floating structure. In the present investigation, a mechanical oscillator model was proposed in order to examine this relationship for the heave motion of a floating wave energy conversion device. Characterisation of the dynamic system optimal behaviour was performed by examining the effect of relative OWC and floating structure natural frequencies, the phase relationships of the various system components and the optimal power take-off damping of the system. It was determined that separation of the …

An Investigation Of The Cognitive And Perceptual Mechanisms Involved In Mania-Proneness, Kimberly Mercer

All Theses and Dissertations (ETDs)

The present research investigates the cognitive and perceptual mechanisms involved in mania-proneness. Building on the work of Depue and colleagues: Depue & Iacono, 1989; Depue & Zald, 1993) and Gray: 1994), which identifies links between the Behavioral Activation System: BAS) and the symptoms observed in mania, this research investigates the hypothesis that people who are prone to mania exhibit cognitive and perceptual biases in information processing when presented with achievement-oriented stimuli both at baseline, and after the receipt of a reward. These hypothesized biases were measured via an affective flanker task, a suboptimal priming task, and a judgment task about …

Perception And Nonconceptual Apprehension, Arnon Cahen

All Theses and Dissertations (ETDs)

My dissertation articulates and resolves a problem at the heart of debates about how perception guides our actions and deliberations. The problem arises from the independent plausibility but mutual inconsistency of the following theses: * Some perceptions provide us reasons * Only belief-like states provide us reasons * No perception is belief-like I argue that this problem is deeper than has been acknowledged. Simply rejecting any one thesis leads to serious challenges. Nonetheless, I argue that we can unravel the link between having reasons and having belief-like states in a way that explains the initial plausibility of the first thesis. …

Comparison Of Quality Of Life Perceptions Of Caregivers Of Individuals With Intellectual Disabilities In The United States And The Czech Republic, Sharon A. Raver, Anne M. Michalek, Jan Michalik, Milan Valenta

Communication Disorders & Special Education Faculty Publications

Caregivers of individuals with disabilities in the United States have been reported to experience additional hardships than families with typical children as they attempt to balance family and work (Parish, Rose, Grinstein-Weiss, Richman, & Andrews, 2008). In this study, 31 caregivers of individuals with intellectual disabilities from the United States and 225 from the Czech Republic completed a qualitative quality of life survey. Similarities in the two groups were found in reported gains and losses from caregiving responsibilities. Differences in perceived spirituality, personal sense of peace and serenity, life optimism, ability to rejoice in life, personal life perspective, health, financial …

Detect, Bite, Slam, Ali Miharbi

Theses and Dissertations

This paper explores the influences, ideas and motivations behind my MFA thesis exhibition. It primarily focuses on how I developed my work for the show in connection to my previous work as well as work created by other artists who explored the impacts of new media in the last decade. With the advancement of social media, digital technologies no longer have their infamous coldness. Our perceptions and the metaphors in language are all reflected onto the machines we create while in return they also shape and redefine our lives. It becomes increasingly difficult to talk about dialectics such as machine-human, …

Kinematic Properties Of Visually And Haptically Guided Actions, Charles E. Pettypiece

Digitized Theses

We compared the contribution of the visual and haptic modalities in action and perception tasks. We also investigated whether or not the dissociation between action and perception found in vision can be duplicated in haptics. For both a grasping and perceptual estimation task, performance based on haptics alone showed greater uncertainty than vision alone. When congruent information from both senses was available simultaneously, performance was no different than with vision alone. When conflict was introduced between the senses, however, an influence of haptic cues emerged. Investigation of Weber’s law in haptics revealed that, like vision, the law was upheld in …

Perception Of Emotion In Sounded And Imagined Music, Brian L. Lucas, Emery Schubert, Andrea R. Halpern

Faculty Journal Articles

WE STUDIED THE EMOTIONAL RESPONSES BY MUSICIANS to familiar classical music excerpts both when the music was sounded, and when it was imagined.We used continuous response methodology to record response profiles for the dimensions of valence and arousal simultaneously and then on the single dimension of emotionality. The response profiles were compared using cross-correlation analysis, and an analysis of responses to musical feature turning points, which isolate instances of change in musical features thought to influence valence and arousal responses. We found strong similarity between the use of an emotionality arousal scale across the stimuli, regardless of condition (imagined …

Acquiring The High Vowel Contrast In Quebec French: How Assibilation Helps, Wendy Baker, Laura Catherine Smith

Faculty Publications

In Quebec French (QF), /t/ and /d/ are assibilated to [ts] and [dz] before /i/ and /y/, but not before /u/. Since the /y/-/u/ contrast is known to be difficult for English speakers learning French as a second language (L2), we examine whether L2 learners of French who have acquired the assibilation rule have any advantage in producing and perceiving the French /i/-/y/-/u/ contrast over L2 learners who produce less or no assibilation in their L2 French. Results demonstrate that L2 learners who are strong assibilators are better at producing vowels similarly to native QF speakers than weak assibilators, but …

The Impact Of L2 Dialect On Learning French Vowels: Native English Speakers Learning Que´Be´Cois And European French, Wendy Baker-Smemoe, Laura Catherine Smith

Faculty Publications

This article examines how a second language (L2) dialect affects how accurately the L2 is perceived and produced. Specifically, the study examined differences between the production and perception of French vowels /i/, /y/, and /u/ by learners of either Quebec French (QF) or European French (EF). These vowels differ across the two varieties, both acoustically and because of assibilation of /t-d/ before /i-y/ for QF versus EF. As a result of these differences, QF has an additional acoustic cue with which to contrast /u/ and /i-y/. Anglophone learners of QF or EF were asked to identify and discriminate both QF …

Investigating The Effects Of Object Connectedness On Rapid Visually-Guided Reaching Toward Multiple Goals, Jennifer L. Milne

Digitized Theses

We developed a rapid reaching paradigm in which we require participants to make speeded reaches toward ambiguous target displays, with a goal target filling-in only after movement onset. In our previous work, we have found that initial reaches extend toward the averaged spatial location of the presented targets. Our aim for the current study was to determine if object connectedness - a strong perceptual illusion in which two connected objects appear as one - could influence the strategic reaching behaviour. Even though there was a powerful effect of the illusion on perception, the visuomotor system was able to utilize the …
