Title: OUTCOMES OF FAMILY PRESENCE DURING RESUSCITATION (FPDR) IN THE ACUTE CARE SETTING: A REVIEW OF THE LITERATURE.
Creator: Corn, Audra M, D'Amato-Kubiet, Leslee, Moore, Sarah, University of Central Florida
Abstract / Description: Family Presence During Resuscitation (FPDR) remains controversial and is not consistently implemented during resuscitation events or invasive procedures. Evidence has demonstrated positive outcomes produced by implementation of FPDR; such as, decreased rates of post-traumatic stress symptoms, decreased symptoms of anxiety, and depressive symptoms were not significantly different.

Show moreFamily Presence During Resuscitation (FPDR) remains controversial and is not consistently implemented during resuscitation events or invasive procedures. Evidence has demonstrated positive outcomes produced by implementation of FPDR; such as, decreased rates of post-traumatic stress symptoms, decreased symptoms of anxiety, and depressive symptoms were not significantly different. Unfortunately, use of FPDR in the acute care setting is not widely accepted or readily implemented. The primary purpose of this integrative literature review is to evaluate the use of FPDR in the acute care setting. The secondary purpose is to evaluate the health care professional's level of perceived value associated with the outcome of having family present during resuscitation. A systematic literature search was conducted using multiple databases for relevant articles in the English language between 2006 to 2017, including Cumulative Index to Nursing and Allied Health Literature (CINAHL), Educational Resources Information Center (ERIC), Elton B. Stephens Co. Host (Ebsco Host), Medical Literature On-line (Medline), Psychological Information Database (PsychINFO), and PubMed. Search terms included 'family presence during resuscitation', 'family presence', 'pediatrics', 'nurse perceptions', and 'perceptions'. Ten of the nineteen articles suggest the use of FPDR leads to positive outcomes such as decreased post-traumatic symptoms, and decreased anxiety for family members. The use of FPDR can enhance family members' understanding of resuscitation efforts and involves them in their loved one's care. This integrative review indicates the implementation of FPDR can provide benefits for family members of those undergoing CPR and invasive procedures; although the perceptions of the healthcare team remain the barrier to its use.

Show moreVideo games are being studied today more than ever before. The engagement that they generate with the user, if harnessed, is thought to have applications across numerous other fields. Educators especially wish to implement elements of gaming into supplemental activities to help further interest students in the learning process. Many claim that this is because classroom's today are in direct contradiction with the real home life of students. Student's today were born into the fast paced world of the digital realm, frequently multi-tasking between watching television, playing games, doing homework, and socializing. As educators begin to create game like experiences to drive student engagement they will seek to create interactions that foster the psychological phenomena of flow, presence, and engagement. Each of these three processes helps play a key role in what makes video games the attention-grabbing medium that they are. When creating games it would be beneficial to know which type of game mechanics reinforce these phenomena the most. The goal of this study is to investigate, Super Meat Boy and Limbo, two very similar games with very different mechanical representations and see which game is more engaging in these three areas. Twenty- nine participants played one of the two games for forty-five minutes, completed three separate measurements, and were observed throughout the process. The results were analyzed and found one game to indeed be more engaging than the other.

Show moreOne of the oft cited reasons for virtual environments is that they provide experiences with places one would never be able to visit and to perform tasks that would otherwise be dangerous, or inaccessible. The ability to become transported to another environment, such that you think you are "there," is known as presence. Existing presence literature focuses largely on the sensory aspects of virtual environment experiences. However, there is more to experience than what is sensed. This dissertation investigates the theoretical components of holistic experiences in virtual environments. In order to explore the relationship between experiential design and presence, a new evaluation tool was needed. This ultimately led to the development of the Virtual Experience Test. To validate the Virtual Experience Test, an experiment was designed that utilized subjective evaluations regarding game-play in the commercial game Mirror's Edge. Measures of experiential design, flow, and presence were taken and the relationships between the measures analyzed. The results of this research showed that environments utilizing holistic designs result in significantly higher presence. Furthermore, this study produced a validated measure of holistic experience that designers could use to evaluate their virtual environments.

Show morePrior research has shown that positive psychological states and attitudes are known outcomes in students who are engaged on their college campus. Although many studies prove this to be evident, literature lacks examination between these two variables. The purpose of the current study was to find a cognitive link between student engagement and the measured outcomes of self-esteem, college self-efficacy, college affiliation, and levels of optimism/pessimism. The study proposed that there is a process of developing an internal sense of presence on campus, which occurs in those students that are actively engaged in activities outside of the classroom. Individual personality traits are additionally measured as a variable for tendencies of involvement. Measurements of presence level in students were analyzed by administering a Campus Presence Scale, modified from the Witmer & Singer Presence Scale. The study subscales that examine levels of student engagement and its outcomes were measured in an online questionnaire format via Qualtrics. A total of 371 students at the University of Central Florida participated in the study. This study hypothesized that students who spend more time on campus engaged in co-curricular activities would display higher levels of presence development. The study also sought a flow of development in these processes, hypothesizing that campus presence mediates the actions in which students engage and their psychological well-being and attitudes towards their institution. Analyses in SPSS were used to examine these relationships. Results indicated that presence is significantly correlated with higher student self-esteem, self-efficacy, college affiliation, and optimism. Results also showed that those involved with student organizations and those who regularly attend campus events are significantly more extroverted and have higher levels of presence, college affiliation and self-efficacy

Show moreThe purpose of simulation is to avoid reality-based constraints by the implemen-tation of a synthetic model. Based on this advantage, interactive simulations have conquered all areas of applications from acquisition, and training, to research. Simulation results are transferred in many ways into reality and conclusions are drawn from the simulation to the application. Many anecdotal observations on human-in-the-loop simulations have shown a significant difference in actor behavior between simulations and reality-based applications. It seems that the factors that makes simulation so attractive, namely the absence of constraints and especially of imminent danger for persons and equipment, influence the behavior and thereby the performance of the user. These differences between simulation and reality may lead to false conclusions based on simulation results. The concept of perceiving a simulation as real and of being in the simulation is called sense of presence. This psychological construct can also be described as level of disbelief towards the simulation. Hence, differences in behavior are based on such users assessment of a simulation and subsequently are supposed to be mediated by a difference in presence. This research established significant differences in presence and performance between a simulation and a miniature-world teleoperation task. Presence and performance changed in identical tasks due to the application type and the connected danger to the robot. Also, the results supported a negative relationship between presence and performance: presence increased in the miniature-world and affected performance so that performance decreased. The causal relationship of application type presence performance was established and demands the examination of simulation based results with respect to the perceived danger to equipment, before they are transferred into the real application.

Show moreThe United States Army continues to develop new and effective ways to use simulation for training. One example is the Non-Rated Crew Member Manned Module (NCM3), a simulator designed to train helicopter crewmembers in critical, high risk tasks such as crew coordination, flight, aerial gunnery, hoist and sling load related tasks. The goal of this study was to evaluate visual modalities' effect on performance in mixed reality aerial door gunnery.There is a strong belief in the United States Army that the greater the degree of immersion in a virtual simulation, the more effective that simulation is. However, little scientific research exists that supports this notion. In fact, the true goal of training simulation is to optimize the degree of transfer to the trainee - not to create the most immersive experience possible. As a result, the Army Program Manager frequently faces trade-off dilemmas during the simulation design phase, balancing user desires with cost and schedule constraints. One of those trade-off predicaments, and the unscientific manner in which it was resolved, served as the motivation for this research.A review of the literature was conducted in order to investigate the benefits of simulation for training. The taxonomy of reality, as well as the training efficacy of virtual and mixed reality simulation, were examined. Major concepts, applications and components of virtual and mixed reality simulation training were studied. Prior visual modality research was reviewed and discussed. Two discrete groups of subjects, expert (n = 20) and novice (n = 76), were employed in this study. Participants were randomly assigned to one of two visual modality treatments (Liquid Crystal Display (LCD) flat panel screen or Head-Mounted Display (HMD)) and executed three aerial door gunnery training scenarios in the NCM3. Independent variables were visual modality, trial, immersive tendency and simulator sickness questionnaire scores. Dependent variables included performance, presence and simulator sickness change scores. The results of the study indicate no main effect of visual modality on performance for the expert population while a main effect of visual modality on performance was discovered for the novice population. Both visual treatment groups experienced the same degree of presence and simulator sickness. No relationship between an individual's immersive tendency and their performance and level of presence was found. Results of this study's primary objective are conflicting, by expertise group, and thus both support and challenge the commonly held notion that higher immersive simulation leads to better performance.

Show moreThe study of the subjective gameplay experience spans multiple disciplines, from teachers who want to harness the power of gameplay to enhance instruction to game developers hoping to create the next big hit. Despite decades of interest, little agreement has been found regarding the way constructs(-)such as immersion, involvement, presence, and flow(-)are used to describe the subjective gameplay experience. Without the consistent usage of well-defined constructs, it becomes impossible to further scientific understanding of this domain. This dissertation examined the theoretical evolution of the key subjective gameplay experience constructs. From this, definitions for immersion, involvement, presence, and flow were extracted. Based on the prior work of Brockmyer et al. (2009), a revised game engagement model was created that incorporated these definitions. To test the proposed relationships within the revised game engagement model, experienced players of the computer game Minecraft were recruited for an experimental study. The participants played the game Minecraft, which was manipulated with respect to both level of difficulty and immersive aspects. This allowed for a range of potential game engagement states to be experienced by the participants. Several individual differences hypothesized to influence the different constructs of game engagement also were measured. The results of the study supported many proposed aspects of the revised game engagement model and revealed ways in which the model could be further refined. The theoretically-derived definitions and revised game engagement model resulting from this work, along with the suggested measures for these relevant constructs, provides a framework for future work in this area. This framework will improve the consistency of construct operationalization, benefiting the continued study of the subjective gameplay experience.

Show moreThe purpose of this study was to investigate the relationship between the level of student motivation and perceived online social presence in an online course. Better understanding of the relationship between online social presence and motivation would assist researchers to identify and develop effective instructional strategies for the success of students' online learning experience. This study was conducted during the Fall 2007 semester at the University of Central Florida (UCF) in Orlando, Florida. Data for this study were collected from participating students enrolled in three online sections of EME 2040, Introduction of Educational Technology. In this course, pre-service teachers learn how to use technology and, more importantly, how to integrate it into their courses and their future classrooms. Three instruments were used in this study to obtain students' demographic information and to measure students' online social presence feeling, students' motivation levels, and instructors' verbal immediacy behaviors. Data were analyzed using repeated measure and multiple linear regression analysis. Seventy-four students from three online sections of EME 2040 responded to the study. Results suggested that students' level of online social presence increased significantly from the beginning of the semester to midterm and then dropped back to the original level from midterm to the end of the semester. However, the level of student motivation significantly increased only from the beginning of the semester to midterm and remained at same level for the rest of the semester. There were significant correlations between online social presence and student motivation across the semester. The regression analysis indicated that verbal immediacy affected online social presence significantly. Further research should be conducted with a larger sample and with different types of online courses in different academic settings and course management systems. Causal relationship between online social presence and student motivation should be explored. Instructional strategies should be established to enhance students' online social presence.

Show moreThe subjective experience of presence is considered to be important in the treatment of anxiety disorders using virtual reality. Presence can be defined as a psychological phenomenon through which one's cognitive processes are oriented towards another world. Most of the research on presence has focused on the roles of technological factors influencing presence, while the number of studies focusing on the personality and physiological predictors are far fewer. Thus, the present study examined the relationship between various personality variables and presence, along with physiological correlates of presence when engaged in a virtual environment. The Presence Questionnaire, to determine their experience of presence, and a small battery of personality-related questionnaires were administered to 70 young adults who participated in 3 different virtual reality scenarios. Participants' physiological responses were recorded in the form of heart rate, galvanic skin levels, and galvanic skin responses were assessed as were urges to drink (craving). Data analysis showed that expectations, levels of craving, and drinking history played a significant role in the experience of presence.

Show moreThis research synthesizes existing research findings that social presence (sense of connection with others) and physical presence (sense of being there) increase learning outcomes in Virtual Learning Environments (VLEs) with findings that traditional motion tracking of participants wearing head mounted displays in virtual reality increases both physical and social presence. This information suggests that motion tracking in mixed reality VLEs has a positive impact on social presence and on physical presence. For this study, the affordance of free movement among virtual objects is enabled by Microsoft Kinect tracking of the user's position that is translated to movement of the virtual camera to simulate user movement and proximity to elements of the virtual environment.This study used a mixed method, multimodal approach including qualitative, subjective, objective, and physiological data to measure social and physical presence. The testbed for this research was TLE TeachLivE(TM), a mixed reality classroom populated with virtual students. The subjective measures are 1) modified Witmer and Singer Questionnaire and 2) Social Presence Instrument (Bailenson, 2002b). The objective measure is a literature based Social Presence Behavioral Coding sheet used to record frequency of occurrences of factors of social presence. Finally, the physiological measure is heart rate as recorded by the MIO Alpha. The primary contribution of this study was that the hypotheses that the affordance of movement in a mixed reality classroom has a positive impact on user perception and experience of a) physical presence and b) social presence in a VLE were supported. This hypothesis was supported in all three measures. The secondary contribution of this research is the literature based Social Presence Behavioral Coding. The final contribution of this research is a research framework that integrates subjective, objective, and physiological measures of social presence in one study. This approach can be applied to various user experience research studies of various VLEs. Finally, in addition to general alignment of the physiological, objective, and subjective measures, there were anecdotal instances of factors of social presence occurring simultaneously with increased heart rate.

A quantitative field experiment involving 48 participants who had just viewed a religious Internet broadcast was undertaken. Individual differences in personality and religiosity are examined in tandem with (tele)presence as predictors of a number of outcome variables, including memory, enjoyment of the online worship service and behavioral intention to be more active with the church. The results showed no significant relationship between religiosity and the experience of (tele)presence, but that users who experienced greater (tele)presence enjoyed the service more, had a greater ability to recognize information from the service, and had a greater intention to attend in the future. The implications for online worship services, along with the limitations of this study, are discussed.

Show moreThe purpose of this research study was to explore the impact of specific Web 2.0 tools on students' experience of teaching, social, and cognitive presence and motivation when enrolled in a very large hybrid course. With online course enrollments continuing to grow at a higher rate than traditional enrollments in higher education (Allen (&) Seaman, 2011) and universities increasing class sizes as a way to meet this demand with fewer fiscal resources, it is imperative to find ways to keep students engaged and motivated when enrolled in very large classes. This study used the Community of Inquiry framework (Garrison, Anderson (&) Archer, 2000) to examine the effect of specific Web 2.0 tools (asynchronous discussion, streaming lectures, multimedia lecture demonstrations, Twitter, and the Second Life virtual world) on teaching, social, and cognitive presence and motivation. The sample population for this study (n = 567) consisted of undergraduate students enrolled in a very large hybrid accounting course in the fall of 2010 at the University of Central Florida. The total enrollment for the course was 943 students. Students could attend face-to-face (f2f) class sessions in a large lecture room that seated 285 students or they could view a streaming video capture of the lectures online. Students were not required to attend the f2f class sessions and could complete the course entirely online.Data were analyzed using one-way analysis of variances (ANOVA), and results of the statistical analyses indicated that students who frequently used the Web 2.0 tools had statistically significant higher mean motivation scores than students who did not use the tools as frequently. Additionally, students who frequently attended the f2f sessions had statistically significant higher mean social presence scores compared to students who attended sometimes or not at all. Attending the f2f sessions, however, did not result in higher mean scores of teaching or cognitive presence.When examined for the impact of the specific Web 2.0 tools, analysis of the ANOVA results indicated that students who used the discussion, streaming lectures, multimedia lecture demonstrations, and Twitter all of the time had significantly higher mean scores of teaching, social, and cognitive presence compared to those students who used the tools less frequently. Further research should be conducted on large hybrid and online courses in different content areas and on those that use different types of learning approaches.

Show moreExposure therapy (ET) is an extensively studied and supported treatment for anxiety and trauma-related disorders. ET works by exposing the patient to the feared object or situation without any danger in order to overcome the related anxiety. Over the past few years, various technologies including head-mounted displays (HMDs), scent machines, and headphones have been used to augment the exposure therapy process by presenting multi-sensory cues (e.g., sights, smells, sounds) to increase the patient's sense of presence. While studies have shown that scents can elicit emotionally charged memories, no prior research could be identified that examined the effect of olfactory stimuli upon the patient's sense of presence during exposure tasks. In this study, the effect of olfactory stimuli on subject's sense of presence was assessed via psychophysiological response (electrodermal activity), visual scanning, and self-report measures. Linear Mixed Modeling showed relationships between olfactory stimuli and presence ratings as well as self-reported anxiety levels, but not visual scanning or physiological arousal. Recommendations were made for continued research in the union of olfactory stimuli, presence, and exposure therapy.

This study aimed to look at the effects of emoticons on relationships, specifically between a leader and member. Participants were asked to read a fake email from a fake boss and answer several questions in regard to leader-member exchange, affective presence, perceived message positivity, perceived masculinity/femininity of the fake boss, and perceived professionalism. This study found that the use of a positive emoticon in an email message increased leader-member exchange, mediated by positive affective presence (though the use of the emoticon and positive affective presence were not linked). This study also found that when participants received a message with an emoticon, they found the sender to be both more feminine and less professional.

Show moreLoneliness among older adults is a problem with severe consequences to individual health, quality of life, cognitive capacity, and life-expectancy. Although approaches towards improving the quality and quantity of social relationships are the prevailing model of therapy, older adults may not always be able to form these relationships due to either personality factors, decreased mobility, or isolation. Intelligent personal assistants (IPAs), virtual agents, and social robotics offer an opportunity for the development of technology that could potentially serve as social companions to older adults. The present study explored whether an IPA could potentially be used as a social companion to older adults feeling lonely. Additionally, the research explored whether the device has the potential to generate social presence among both young and older adults. Results indicate that while the devices do show some social presence, participants rate the device low on some components of social presence, such as emotional contagion. This adversely affects the possibility of a social relationship between an older adult and the device. Analysis reveals ways to improve social presence in these devices.

Show moreThe purpose of this study was to determine if the Technology Acceptance Model (TAM) could explain the relationship between teacher's acceptance of an online teacher professional development course and their continuance intentions regarding online teacher professional development (oTPD). This study focused on the perceptions of the teachers as opposed to the design or implementation of oTPD. The participants (N=517) were mostly teachers (88.8%) enrolled in a statewide online course to provide classroom teachers with the latest knowledge of research-based instructional reading strategies. The course was offered over a 10-14 week period during the Spring 2006 semester through a public state university. Structural equation modeling was used to create a path analytic model extending the TAM to include two additional constructs: sociability and social presence. In addition, gains in instructional reading strategies knowledge (performance) were examined. Using this expanded version of the TAM, the study examined the causal relationships between sociability, social presence, perceived usefulness, perceived ease of use, continuance intention, and gains. Online distance education research has indicated that social presence can influence post-secondary students' attitude and persistence within a web-based course. However a paucity of research exists on how technology acceptance and social presence impacts teachers within an online teacher professional development setting. Path analysis, univariate analysis of variance, and independent t-tests in SPSS v12.0 for Windows were used to analyze the data. The results suggest that the hypothesized extended model was a good fit. The model did indicate that both perceived ease of use and perceived usefulness were determinants of teachers' intent to continue using oTPD for future professional development needs.

Show moreThe purpose of this research study was to use the Technology Acceptance Model (Pan, 2003) for re-examination of the relationships between students' attitude toward the use of WebCT and the relevance of the actual usage in light of social presence and sociability. By using Technology Acceptance Model (TAM) developed by F. Davis (1989), this study focused on variables such as perceived usefulness, perceived ease of use, computer self-efficacy, subjective norms, attitude and actual use of WebCT to account for the effect towards the achievement in the exam which is an outcome variable. The data were collected over three different time periods during the spring semester of 2007 to find how these results changed over time. The participants were the students who enrolled in the business marketing course (Principle of marketing) at the University of Central Florida in spring, 2007. The course was divided to three sections: on-campus, video-streaming and online classes. Although there were three different delivery methods, there was only one instructor and they used same material for all sections so the results were used to compare the differences from three classes. The study was conducted by using instruments to measure perceived usefulness, perceived ease of use, computer self-efficacy, subjective norms, actual use, attitude, sociability, social presence and an additional demographic instrument.

Show moreThe Community of Inquiry model provides a framework for recognizing and evaluating interpersonal behaviors in online educational settings. One of its three components, teaching presence (TP), describes those behaviors that are under the auspices of the online instructor. By examining these interactions and behaviors through the theoretical lens provided by teaching presence, and by measuring them with the Teaching Presence Scale (TPS), it may be possible to gain greater understanding of the practices employed most effectively by online instructors. This dissertation describes the background, theoretical and empirical foundations, methods, and results of a study on TP. The purpose of the study was threefold: to validate the use of the TPS in an online professional development setting outside of the higher education context in which it was designed and tested; to confirm the factor composition of TP among facilitators in an online professional development course; and to determine the extent and direction of the relationship between teaching presence and student satisfaction. The participants in this study (n = 718) were in-service educators enrolled at the Florida Online Reading Professional Development program. They responded to an instrument that included the 28 original TPS questions, plus 17 student satisfaction and 11 demographic items. Confirmatory factor analysis and Pearson's correlation were used to answer the three research questions and corresponding hypotheses. The research questions were answered in the affirmative, and the null hypotheses rejected. There was support for the use of the TPS in an online professional development setting (all 28 TPS items loaded as hypothesized on the three TP factors); support for a three-factor model of TP using 17 of the 28 TPS items (X2 [116, N = 718] = 115.56, p = .49, CFI = .999; NNFI = .999; SRMR = .02; and RMSEA = .03); and evidence of a strong relationship between components of TP and student satisfaction (statistically significant correlations [p < .001] between TP and student satisfaction, r2 values ranging from .25 to .57). A discussion of the results, implications for practice, implications for further research, and limitations of the study were presented following the data analysis.

Show moreperson's sense of acceptance of a virtual body as his or her own is generally called virtual body ownership (VBOI). Having such a mental model of one's own body transferred to a virtual human surrogate is known to play a critical role in one's sense of presence in a virtual environment. Our focus in this dissertation is on top-down processing based on visual perception in both the visuomotor and the visuotactile domains, using visually personalized body cues. The visual cues we study here range from ones that we refer to as direct and others that we classify as indirect. Direct cues are associated with body parts that play a central role in the task we are performing. Such parts typically dominate a person's foveal view and will include one or both of their hands. Indirect body cues come from body parts that are normally seen in our peripheral view, e.g., legs and torso, and that are often observed through some mediation and are not directly associated with the current task.This dissertation studies how and to what degree direct and indirect cues affect a person's sense of VBOI for which they are receiving direct and, sometimes, inaccurate cues, and to investigate the relationship between enhanced virtual body ownership and task performance. Our experiments support the importance of a personalized representation, even for indirect cues. Additionally, we studied gradual versus instantaneous transition between one's own body and a virtual surrogate body, and between one's real-world environment and a virtual environment. We demonstrate that gradual transition has a significant influence on virtual body ownership and presence. In a follow-on study, we increase fidelity by using a personalized hand. Here, we demonstrate that a personalized hand significantly improves dominant visual illusions, resulting in more accurate perception of virtual object sizes.

Title: The Effects of Presence and Cognitive Load on Episodic Memory in Virtual Environments.
Creator: Barclay, Paul, Sims, Valerie, Bowers, Clint, Jentsch, Florian, Fiore, Stephen, University of Central Florida

Show moreEpisodic memory refers to an individual's memory for events that they have experienced in the past along with the associated contextual details. In order to more closely reflect the way that episodic memory functions in the real world, researchers and clinicians test episodic memory using virtual environments. However, these virtual environments introduce new interfaces and task demands that are not present in traditional methodologies. This dissertation investigates these environments through the lenses of Presence and Cognitive Load theories in order to unravel the ways that basic technological and task differences may affect memory performance. Participants completed a virtual task under High and Low Immersion conditions intended to manipulate Presence and Single-Task, Ecological Dual-Task and Non-Ecological Dual-Task conditions intended to manipulate cognitive load. Afterward they completed a battery of memory tasks assessing spatial, object, and feature binding aspects of episodic memory. Analysis through 2x3 ANOVA showed that performance for spatial memory is greatly improved by manipulation of Presence, where performance for object memory is improved by germane cognitive load. Exploratory analyses also revealed significant gender differences in spatial memory performance, indicating that improving Presence may offset the higher levels in male performance traditionally seen on spatial tasks. These results have practical implications for clinical memory assessment, as well as training paradigms and may serve to highlight the differences in the ways that memory is studied in the laboratory versus the way that it is employed in day-to-day life. Future studies based on this research should focus on linking these differences in memory performance to visuospatial and verbal strategies of memorization and determining whether the effects observed in this study replicate using other manipulations of presence and cognitive load.
