Virtual Reality (VR) is gaining more and more popularity as a research tool in the field of Human-Robot Interaction (HRI). To fully deploy the potential of VR and benefit HRI studies, we need to establish the basic understanding of the relationship between the physical, real-world interaction (Live) and VR. This study compared Live and VR HRI with a focus on proxemics, as proxemics preference can reflect comprehensive human intuition, making it suitable to be used to compare Live and VR. To evaluate the influence of different modalities in VR, virtual scenes with different visual familiarity and spatial sound were compared as well. Lab experiments were conducted with a physical Pepper robot and its virtual copy. In both Live and VR, proxemics preferences, the perception of the robot (competence and discomfort) and the feeling of presence were measured and compared. Results suggest that proxemic preferences do not remain consistent in Live and in VR, which could be influenced by the perception of the robot. Therefore, when conducting HRI experiments in VR, the perceptions of the robot need be compared before the experiments. Results also indicate freedom within VR HRI as different VR settings are consistent with each other.

This qualitative case study examined the impact of an arts integrated international collaboration on elementary school students’ creativity when the students were communicating and creating exclusively through a technological third space. Two organizations, one in the U.S. and one in Mexico, served as the sites for the case study. Five findings emerged from the study relating to the nature of creativity and two findings related to the impact on students’ creativity when engaged in arts-integrated international collaboration. The findings for the first question were: 1. Students and teaching artists view creativity as a process that is reflexive and engaging, 2. When reflecting on their work, students and teaching artists see creativity as an interplay of ideas and are open to and capable of modifying their ideas to achieve creative results, 3. Creative work is relative to the individual and is directly correlated to both originality and effort, 4. Students and teaching artists value creativity as a means for both self-expression and communication, 5. A collaborative environment sets the stage for creative behavior in terms of inviting feedback, providing constructive criticism, and sharing ideas. For the second question relating to impact, the two findings were: 1. Teaching and learning in the third space becomes a recursive process, and 2. Students work in new modes of communication in order to bridge cultures. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

Visual-spatial skills deficits are one of the primary neuropsychological deficits among children with Nonverbal Learning Disability (NVLD; Rourke, 1989) and Asperger's Syndrome (AS; Ellis, & Gunter, 1999; Klin, Volkmar, Sparrow, Cicchetti, & Rourke, 1995). In addition to affecting written tasks, visual-spatial deficits also have implications for the social functioning of children. Children who are not able to accurately process visual-spatial information will have difficulty processing the visual, nonverbal cues present in social situations including facial expressions, hand movements, and body posture (Nowicki & Duke, 1992). These social perception deficits make social interactions difficult for these children. As a result of their social differences, they are likely to get negative reactions from others, have social skills deficits (Petti, Voelker, Shore, and Hayman-Abello, 2003), and have much difficulty fitting in with same-aged peers. These social skills deficits will likely lead to internalized adjustment problems in which these children feel isolated, withdrawn, and depressed around their peers. This sequence of events, visual-spatial deficits, followed by social perception deficits, followed by social skills deficits, which ultimately lead to internalized emotional problems, is implied, but not empirically proven, in a study by Petti and colleagues (2003). In addition to experiencing greater socioemotional problems than other LD subtypes, visual-spatial and social deficits of children with NVLD have been shown to worsen with age (Casey, Rourke and Picard, 1991). This dissertation study investigated the relation between these four constructs (i.e., visual-spatial skills, social perception, social skills, and internalized emotional functioning). It was hypothesized that social perception and social skills mediate the relationship between visual-spatial skills and internalized emotional functioning. In addition, these deficits were expected to increase as these children get older. As NVLD and AS are commonly co-morbid with Attention Deficit/Hyperactivity DisorderPredominantly Inattentive Type (ADHD: PI; Gross-Tsur & Shalev, 1995; Voeller, 1996), this diagnostic group was compared to children diagnosed with ADHD: PI. An additional aim of this study was to differentiate the classification of Learning Disability (LD) by demonstrating the socioemotional functioning differences between individuals with NVLD/ADHD: PI and their counterparts -- individuals with a Verbal Learning Disability (VLD/ADHD: PI). Seventy-one children, ranging in age from 8-14 participated in the study and were assigned to one of three groups (e.g., NVLD/AS with ADHD: PI, VLD with ADHD: PI, or ADHD: PI) based on pre-determined criteria. The NVLD/AS group, as expected, showed impairments in all areas (i.e., visual-spatial skills, social perception, social skills, and internalized socioemotional functioning) and significantly differed from one or both of the other groups on each of the four domains. Support was not found for the age effects for the NVLD/AS group. That is, visual-spatial and internalized socioemotional scores did not worsen with increasing age as expected. Also, visual-spatial skills were not significantly related to internalizing socioemotional functioning, and the hypothesized mediation variables were not statistically significant. The current study contributes to the understanding of individuals with NVLD, an under-studied population. The proposed visual-spatial skills deficits and social perception deficits in Rourke's (1989) theoretical model were supported. This study also offers some insight into the internalizing socioemotional functioning of children with NVLD. It clarifies the heterogeneity of socioemotional functioning among LD children, suggesting that it is children with the LD subtype, namely NVLD, who are at greater risk for social problems. / text

Following the postmodern discourses of spatial conceptualisation, this study examined the manner in which space in an Open Distance Learning (ODL) University enables or constrains academics’ work as they go about the process of constructing their academic identities. Focusing on academics’ engagement in one college of the University, the study was premised on the assumption that, in the current higher education (HE) dispensation, academic identity construction presumes and demands the existence of supportive space for academics to effect the academic practices. Lefebvre’s (1991) social production of space and Soja’s (1996) Thirdspace were used as lenses to examine the multiple dimensions of space in relation to spatial practices in the College, the spatial policies and the experiences of academics as the users of the Institutional space. Qualitative ethnographic research methods that were used to collect data included a review of the Institutional policies, intranet posts and emails; the observation and photographing of academics’ offices and administrative office space; observation of departmental meeting proceedings and the conducting of semi-structured interviews with academics of different academic ranks. Findings suggested that although some forms of space are supportive of spatial practices that contribute to academic identity construction, the imagined space of the ODL Institution can be unfairly inclusive and inconsiderate of academics’ unique spatial needs. Such inclusivity of space seemed to be inconsistent with the appropriate ODL space as imagined by some participants where academics may work comfortably and with limited restrictions. The study concluded by making recommendations on how the Institution and the academics may manage space for optimal academic identity construction in the College. / Educational Foundations / D. Ed.

The understanding of the subjective experience of a visually stable world despite the occurrence of an observer's eye movements has been the focus of extensive research for over 20 years. These studies have revealed fundamental mechanisms such as anticipatory receptive field (RF) shifts and the saccadic suppression of stimulus displacements, yet there currently exists no single explanatory framework for these observations. We show that a previously presented neuro-computational model of peri-saccadic mislocalization accounts for the phenomenon of predictive remapping and for the observation of saccadic suppression of displacement (SSD). This converging evidence allows us to identify the potential ingredients of perceptual stability that generalize beyond different data sets in a formal physiology-based model. In particular we propose that predictive remapping stabilizes the visual world across saccades by introducing a feedback loop and, as an emergent result, small displacements of stimuli are not noticed by the visual system. The model provides a link from neural dynamics, to neural mechanism and finally to behavior, and thus offers a testable comprehensive framework of visual stability.

Irena Lehkoživová Between Architecture and Art: Reception of Mutual Relationships Doctoral thesis Abstract My doctoral thesis deals with the relationship between contemporary architecture and fine art. I track examples of such concepts and approaches in which architecture and art permeate and influence each other. Besides, I examine how selected authors approach the chosen topic. A detailed analysis of the work and ideas of individual selected architects or artists is thus complemented by clarification of their methods and starting points. The aim of this work is to look at the predefined studied subject and the context behind it, to explain the associated concepts, strategies and the functioning of mechanisms, and the transfer of themes, procedures and techniques of creation. The thesis consists of three chapters, separate case studies. The first chapter follows the tendencies and changes in displaying architecture, which, under the influence of art, tends to create more complex viewing experiences. I describe here two examples and approaches that come out of this tendency. In the first part, it is the approach to the exhibitions of the Swiss duo Herzog & de Meuron, the second part is devoted to the architectural installations, which under the influence of installation art allow the visitor a direct...

Numerical cognition has been shown to share many aspects of spatial cognition, both behavioural and neurological. However, it is unclear whether a particular type of spatial cognition, visuospatial mental imagery (VSMI), may play a role in symbolic numerical representation. In this thesis, I first show that mental rotation, a form of VSMI, is related to two measures of basic numerical representation. I then show that number-space synaesthesia (NSS), a rare type of VSMI involving visualised spatial layouts for numbers, does not show an advantage in mental rotation, but shows interference in number line mapping. I next present a study investigating links between NSS and the ability to learn novel numerical symbols. I demonstrate that NSS shows an advantage at learning novel numerals, and that transcranial random noise stimulation, which increases cortical excitability, confers broadly similar advantages that nonetheless differ in subtle ways. I present a study of transcranial alternating current stimulation on the same symbol learning paradigm, which fails to demonstrate effects. Lastly, I present data showing that strength of numerical representation in these newly-learnt symbols is correlated with a measure of mental rotation, and also with visual recognition ability for the symbols after, but not before, training. All together, these findings suggest that VSMI does indeed play a role in numerical cognition, and that it may do so from an early stage of learning symbolic numbers.

Indiana University-Purdue University Indianapolis (IUPUI) / Despite warnings about the dangers of drinking during pregnancy, little progress has been made in reducing alcohol drinking among women of childbearing age. Even after the recognition of pregnancy, 15% of women continue to drink, 3% of which admit to binge drinking. Because we cannot stop women from drinking during pregnancy, and many children with fetal alcohol spectrum disorders (FASD) are adopted, there is a significant need to develop postnatal interventions that can improve the long-term outcome of children adversely affected by prenatal alcohol exposure. This thesis aims to evaluate one promising new treatment in the rehabilitation or rescue of specific learning deficits long after the damage has occurred. The treatment evaluated herein (40µg D-NAP + 40µg D-SAL) has long been used in the prevention of the detrimental effects of long-term and binge-like alcohol exposures in rodent models of fetal alcohol syndrome and FASD. Until recently this peptide treatment had only been shown to be effective in preventing some of the consequences of alcohol exposure when administered concurrently with the prenatal alcohol exposure. A recent report by Incerti and colleagues (2010c), however, reported that these peptides could completely reverse a profound spatial learning deficit induced by one episode of a heavy binge-like alcohol exposure (5.9g.kg in a single intraperitoneal injection) on gestational day 8 (G8) in C57BL/6 mice. In that report, the peptide treatment was administered starting in late adolescence, beginning three days prior to and throughout water maze training, and the profound deficits in their alcohol-placebo group were completely eliminated in the alcohol-peptide group. There are currently no FDA-approved treatments for FASD. An effective treatment for the cognitive and behavioral dysfunctions suffered by the 1% of people born today could potentially improve the lives of millions of children and adults. The first aim of this thesis was to determine whether the peptide treatment could reverse the significant spatial learning deficits we have demonstrated in adult C57BL/6 mice given high-dose binge-like alcohol exposure (2.5 g/kg in each of two intraperitoneal injections separated by two hours) on postnatal day (P)7. When administered three days prior to and throughout water maze testing (P67-76), the peptide treatment had no effect on spatial learning. The second aim sought to determine whether the same peptide treatment could reverse water maze spatial learning deficits in G8 binge-like exposure models, as reported by Incerti et al. (2010c). For this analysis, the first study used a different binge-like alcohol exposure model that is more commonly used than that employed by the Incerti et al. (2010c) study, namely administration of 2.8g/kg in each of two intraperitoneal injections separated by four hours (Sulik et al., 1981). This model has been shown to produce high peak blood alcohol concentrations and neuroanatomical aberrations in the hippocampal formation and septal regions (Parnell et al., 2009), which have been implicated in learning and memory. Surprisingly, this G8 binge-like alcohol exposure failed to produce a spatial learning deficit, undermining the usefulness of this model in evaluating the peptide effects. In direct contrast to the outcomes of Incerti et al. (2010c), the G8 Webster alcohol exposure was also unable to produce any deficits in acquisition of spatial learning in the Morris water maze. Surprisingly, neither of the heavy binge-like alcohol exposures on G8 were able to produce spatial learning deficits in the Morris water maze. The binge-like alcohol exposure on P7 did yield the expected spatial learning deficit, but the peptide treatment was unsuccessful in recovering water maze learning. These findings fail to support oral administration of 40µg D-NAP and 40 µg D-SAL as a potential therapy for postnatal alcohol-induced spatial learning deficits in adult mice.
