No / This chapter discusses important aspects of visual representations and interaction techniques necessary to support visual analytics. It covers five primary topics. First, it addresses the need for scientific principles for depicting information. Next, it focuses on methods for interacting with visualizations and considers the opportunities available given recent developments in input and display technologies. Third, it addresses the research and technology needed to develop new visual paradigms that support analytical reasoning. Then, it discusses the impact of scale issues on the creation of effective visual representations and interactions. Finally, it considers alternative ways to construct visualization systems more efficiently

My thesis focuses on the perceptive afflictions caused by alteration of the normal biological functioning of sight and memory. These afflictions are related to the redefinition and disgregation of the classical and postclassical cinematographic characters, and affect cinematographic language, establishing a dialectical relation with the filmic image that contaminates our spectatorial perception. In the first chapter I propose a different reading of a few moments in film history, turning points in which a modification of the ordinary sensorial patterns has been introduced. From the German Expressionism to the late authorial experiments of the 60s, there is a sort of hidden history of film that passes through the continuous redefinition of the audience sensory activity. The different perspective upon broadly studied topics leads to the analysis of contemporary cinema: my thesis tries to investigate the reasons that led cinema to continually increase the representation of perceptive afflictions during the last years, and theses “affected” narratives of afflictions and dysfunctions have interesting effects upon so called “normal” perception of the reality surrounding us. The chapters 2 and 3 respectively analyze memory disorders and different dysfunctions of sight: these elements determine alterations in the ‘normal’ and ‘sensory’ perception of reality. They work as narrative factors changing the visual filmic instruments and redefining the role of the subject (and his/her uncertain definition of identity) in contemporary narratives that show how new technologies are profoundly transforming (and enhancing) the perceptive mechanisms involved in our spectatorial activity. In this work I analyze those films that are mostly committed to a clear and readable narration. My study primarily concentrates on American cinema of the last 30 years – with particular attention to popular Hollywood productions – because Hollywood has become the privileged ‘laboratory’ for the negotiation of gaze and images in the contemporary mediascape, while during the classical era experimental and avant-garde cinema were the “place” in which audience experienced the most important redefinitions of the boundaries between different types of mediated perception.

Esta pesquisa apresenta uma análise multifacetada para a classificação das representações visuais presentes em questões de química de exames vestibulares de cinco grandes universidades públicas paulistas: USP, UNICAMP, UFSCAR, UNESP e UNIFESP no período de 2007 a 2011. Os vestibulares da UFSCAR e UNIFESP utilizaram o exame do ENEM a partir de 2009 como processo de seleção, assim o exame também foi analisado. Foram encontradas 252 questões contendo representações visuais em provas de conhecimentos gerais e conhecimentos específicos. Alguns exemplos dessas representações incluem gráficos, fluxogramas, diagramas, tabelas, e equações químicas. As representações visuais foram analisadas quanto a suas relações com o texto, sua funcionalidade, conteúdos químicos envolvidos na questão e as habilidades cognitivas requisitadas. Os resultados indicam, de modo geral, que as representações visuais mais frequentes são as equações químicas e as representações bidimensionais da estrutura molecular, com predominância de conteúdos de química orgânica e físico-química. Quanto a relação texto e imagem, destaca-se a grande ocorrência de casos nos quais a integração texto e imagem é necessária para a resolução da questão. No tocante à funcionalidade das representações visuais, salienta-se que: i - as provas envolvem em suas questões ilustrações que necessitam do conhecimento químico para suas interpretações; ii - há predominância de imagens menos realistas e mais interpretativas; iii - a grande ocorrência de etiquetas verbais nominativas. A ênfase em questões de memorização contendo representações visuais também foi investigada adotando-se o referencial de Zoller (1993, 1997, 1999, 2001) para classificar as questões quanto às habilidades cognitivas requisitadas: de alta ou baixa ordem. Os resultados indicam que questões que demandam habilidades cognitivas de baixa ordem são predominantes nas provas de conhecimentos gerais, e questões que demandam habilidades cognitivas de alta ordem em provas de conhecimentos específicos. / This research presents a multifaceted analysis for the classification of visual representations present in chemical questions of entrance examinations of five biggest São Paulo public universities: USP, UNICAMP, UFSCAR, UNESP and UNIFESP from 2007 to 2011. Entrance examinations of UFSCAR and UNIFESP used the exam ENEM from 2009 as a selection process, so the test was analyzed too. 252 questions were found with visual representations in general knowledge and specific knowledge test. Some examples of these representations include graphics, flow charts, diagrams, tables, and chemical equations. The visual representations were analyzed for their relation with the text, its functionality, chemical content involved in the question and the required cognitive skills. The results indicate, generally, that the most frequent visual representations are the chemical equations and the two-dimensional representations of molecular structure with content predominance of organic chemistry and physicochemical. About the relation of text-image, there is a high occurrence of cases in which text and image integration is necessary for the resolution of the matter. Regarding the functionality of visual representations, it is noted that: i - the test involve in his questions, illustrations that requires chemical knowledge for their interpretations; ii - there is predominance of less realistic and more interpretive images; iii - the high occurrence of nominative verbal labels. The emphasis on memorization questions containing visual representations was also investigated adopting the Zoller (1993, 1997, 1999, 2001) reference to classify the questions about the cognitive skills required: high or low order. The results indicate that questions that require lower order cognitive skills are prevalent in the tests of general knowledge, and questions that require higher order cognitive skills of specific evidence.

Data from a growing number of research studies indicate that children with hearing loss are delayed in Theory of Mind (ToM) development when compared to their typically developing, hearing peers. While other researchers have studied the developmental trajectories of ToM in school-age students who are deaf and hard of hearing (DHH), a limited number have addressed the need for interventions for this population. The present study extends the current research on ToM interventions to the PreKindergarten and Kindergarten levels. This study used a single-case multiple-baseline multiple-probe across skills design with replications across classrooms to examine the effects of a ToM intervention on participants’ false belief understanding as well as outcomes on a near generalization measure (i.e., Sally-Anne Task, Baron-Cohen, Firth, Leslie, 1985) and a far generalization measure (i.e., five-task ToM developmental scale, Wellman & Liu, 2004). A thought bubble intervention (i.e., a visual representation of what people are thinking) developed by Wellman and Peterson (2013) was modified in key areas: (a) participants were substantially younger than the population in the original study and thus required a pre-teaching phase addressing vocabulary and materials, (b) manipulable materials were created from the description provided in the Wellman and Peterson (2013) study along with parallel materials used in assessment probes, (c) a certified teacher of DHH children provided direct instruction to participants in a small group setting, (d) study length was increased to 25 weeks, and (e) methodological design change (i.e., group design to single-case design). These modifications addressed the need for evidence-based ToM interventions that are both proactive and easily implemented by teachers in a classroom setting. Results from the single-case design portion of the study indicate a functional relation between the thought bubble intervention and the participants’ acquisition of the targeted skills in each stage, although progress was not uniform. Results from the pre-post assessments indicate that the children did make progress up the scale, however, children who used spoken language tended to proceed faster through the stages than those who used sign language. These results inform the field in regard to the efficacy and feasibility of a ToM intervention for young DHH children.

As the development of the Internet and the rapid increase of data, information visualization is becoming more and more popular. Since human eyes receive visual information very quick and easy, the visualization can make complex and large data more understandable. Describing sensory perceptions, such as taste, is a challenging task. For a customer, the visualization of the taste of a specific wine together with the other wine attributes such as color and grape type would help him/her choose the right one.    In the thesis, two suitable representations of wine attributes are implemented.

To produce norms and beauty ideals through visual representations - A semiotic and multimodal study of how companies construct the “perfect body”.The aim of this qualitative study is to investigate how clothing companies, with the help of visual representations, construct, confirm and/or whether they challenge different norms and ideologies regarding the "perfect body". Based on the above-mentioned research aim, this thesis aspires to answer the following research questions:- How do visual representations on Instagram contribute to constructing, confirming and/or challenging beauty ideals and norms? - What are the norms regarding each gender according to the analyzed visual representations?In order to address the study’s aim and research questions, this study adopts a case study design which is based on qualitative methodology. More specifically, this thesis conducts a multimodal semiotic analysis of a Swedish clothing company’s Instagram posts. Based on a purposeful collection method, the study offers an in-depth analysis of six Instagram posts, considered to be representative of the company’s overall marketing strategy.Drawing from theoretical perspectives such as, social constructivism, social semiotics, self-discrepancy and poststructuralist feminism this thesis shows cases that both can confirm and contest society’s norms and beauty ideals. In summary, this thesis shows that the company under investigation both constructs and contests ideals and norms regarding the "perfect body", for the individual gender. These ideals are confirmed by creating visual representations where only people who meet society's ideals and norms are presented. The company thus does not challenge the notion of the "perfect body", which is a fit and thin body.
