Au croisement de la sociologie de l’action et de l’anthropologie de la communication et du langage, la thèse entend vérifier l’hypothèse de la co-construction d’un outillage collectif de la fabrique de la ville. Elle s’appuie sur une ethnographie de quatre processus participatifs sur des projets urbains franciliens de différentes natures : projet de rénovation et éco projet. La première partie montre comment se dessine un cadre d’action dans lequel la fabrique de la ville devient un projet participatif qui met les acteurs en situation d’enquête collective. Le face à face devient un double espace de projétation - projection des transformations urbaines - et de fabrique des modalités et ressources participatives. Saisir ce double espace nécessite une approche socio-anthropologique.La seconde partie s’intéresse aux contraintes avec lesquelles les participants doivent conjuguer : elle insiste sur les différents cadrages qui contribuent très fortement à la définition d’une offre participative (mises en place dans le cadre de commande public ou encore d’une recherche-action). Les contraintes se situent dans les trois niveaux de l’activité participative (interactionnelle, organisationnelle et politique), ce qui rend l’exercice collectif très complexe. Dans une perspective pragmatiste, la troisième partie s’attache à regarder comment la participation remodèle les ressources de l’échange en face à face et comment elle construit des façons de (faire) participer. Elle insiste sur les obstacles et les leviers d’un outillage collectif. L’étude ethnographique dégage un contraste dans les possibles redéfinitions de la situation qui sont laissées aux acteurs. / Situated between sociology of action and anthropology of communication and language, the thesis intends to verify the hypothesis of a collective tooling for building the city. It is based on the ethnography of four participatory processes in different urban projects situated in the Paris metropolitan area, ranging from the eco-project to the urban renewal project. The first part of the thesis retraces the history of the emergence of the participation, mainly from the point of view of the understanding and the recognition of the city and its inhabitants. It shows how a framework for action when building the city becomes a participative process of collective investigation. The face-to-face becomes a double space of “projétation”. Understanding this needs to develop a socio-anthropological approach.The second part analyses the constraints that the inhabitants have to deal with: it insists on the various framings that contribute very strongly to the definition of the participative offer (organized within the framework of a public order or a research action). These constrains are situated (and can be read) at the same three participative activity levels (interactional, organizational and political), with further complexity for the collective process. Using a pragmatist analytical frame, the third part attempts to describe how the participation process remodels the resources of the face-to-face exchange, and how it builds ways to devise/engage in the participation process. It insists on the obstacles and the levers of a collective tooling of the process. The ethnographical study allowed to identify different possible redefinitions of the situation available to the actors.

This thesis explores the causes of the face inversion effect, which is a substantial decrement in performance in recognising facial stimuli when they are presented upside down (Yin,1969). I will provide results from both behavioural and electrophysiological (EEG) experiments to aid in the analysis of this effect. Over the course of six chapters I summarise my work during the four years of my PhD, and propose an explanation of the face inversion effect that is based on the general mechanisms for learning that we also share with other animals. In Chapter 1 I describe and discuss some of the main theories of face inversion. Chapter 2 used behavioural and EEG techniques to test one of the most popular explanations of the face inversion effect proposed by Diamond and Carey (1986). They proposed that it is the disruption of the expertise needed to exploit configural information that leads to the inversion effect. The experiments reported in Chapter 2 were published as in the Proceedings of the 34th annual conference of the Cognitive Science Society. In Chapter 3 I explore other potential causes of the inversion effect confirming that not only configural information is involved, but also single feature orientation information plays an important part in the inversion effect. All the experiments included in Chapter 3 are part of a paper accepted for publication in the Quarterly Journal of Experimental Psychology. Chapter 4 of this thesis went on to attempt to answer the question of whether configural information is really necessary to obtain an inversion effect. All the experiments presented in Chapter 4 are part of a manuscript in preparation for submission to the Quarterly Journal of Experimental Psychology. Chapter 5 includes some of the most innovative experiments from my PhD work. In particular it offers some behavioural and electrophysiological evidence that shows that it is possible to apply an associative approach to face inversion. Chapter 5 is a key component of this thesis because on the one hand it explains the face inversion effect using general mechanisms of perceptual learning (MKM model). On the other hand it also shows that there seems to be something extra needed to explain face recognition entirely. All the experiments included in Chapter 5 were reported in a paper submitted to the Journal of Experimental Psychology; Animal Behaviour Processes. Finally in Chapter 6 I summarise the implications that this work will have for explanations of the face inversion effect and some of the general processes involved in face perception.

The purpose of this qualitative study was to investigate how asylum seekers may experience different interview methods in the asylum investigation in Sweden. An inductive qualitative data collection technique was used in this study, where semi-structured interviews were conducted with six asylum seekers in four different cities in Sweden. This study was influenced by the grounded theory approach in the way of creating codes, concepts and themes from the empirical data analyzed in thematic and constant comparison method. The results show three different themes, namely ‘‘the expressions of the feelings, possibilities to expressions and possibilities and difficulties.’’ as they present the asylum seekers views of different interview methods. The role theory was chosen in relation to the asylum seekers different behavior toward the interview methods. The results indicated the possibilities for different roles as: ‘‘psychological unbalanced role, technology skilled role, technology challenged role and the apprehensive role’’

The present study provides a comparison of face-to-face and mediated hurtful communication in close relationships. Drawing on previous studies on hurtful communication and computer-mediated communication (CMC), an escalating hypothesis was posited that mediated hurtful messages would be perceived as more controllable, intentional, and hurtful than face-to-face (FtF) hurtful messages. Study 1 tested these predictions. Survey responses from college students who were randomly assigned to report either mediated or face-to-face hurtful interaction with a friend or romantic partner confirmed higher perceived controllability (i.e., being more deliberate on crafting hurtful messages) in the CMC than the FtF condition. Although intent and hurt were not different between the two contexts in the full sample, higher intent was found in CMC than FtF in romantic relationships. Thus, Study 2 was conducted, focusing on a comparison of FtF and text messaging in romantic relationships. Also, perceived face threat and relationship aspects—distancing effect of hurtful interactions and the effect of relationship satisfaction—were assessed. Face threat was posited to be lower in CMC than FtF context since Study 1 suggested that self-focused appraisals (e.g., humiliation) were lower for mediated hurtful messages. This difference in face threat was considered to result in similar levels of intent and hurt between the two contexts, although perceived controllability is higher in CMC. Results of Study 2 confirmed higher deliberation in CMC but failed to confirm higher intent or hurt in CMC. Further, face threat was not different between the two contexts, and controlling for face threat did not reveal the escalating effect (i.e., higher intent or hurt in CMC). Regarding relationship aspects, higher satisfaction and lower intent were associated with less distancing effect, and relationship satisfaction was negatively related to deliberation, intent, hurt, and distancing. These tendencies were not different between CMC and FtF contexts. These results suggest that mediated hurtful communication is a complex phenomenon in which various factors should be considered. The implications of these results were discussed, and suggestions for future studies were also offered. / text

Previous research has demonstrated that men and women employ different speech styles that result in an uneven power dynamic. To better understand the increasingly common interactions that take place using video-mediated communication, such as Skype and Google Hangout, the present research examines these gendered patterns in video-mediated communication (VMC). Mixed-gender dyads will be formed and ask to complete a desert survival task via VMC or in person while software analyzes their use of aggressive positive, and tentative language, as well as measuring speaking time for each party. Interpersonal perception and the use of intrusive interruptions and will also be examined. Drawing from research in Social Information Processing Theory, it is expected that users compensate for the difficulties of a communication medium in order to achieve a normal interaction. As such, men are anticipated to use more intrusive interruptions, aggressive language, and speak more than women, regardless of condition. Women are anticipated to use more positive and tentative language in both VMC and face-to-face conditions. Dominant language is also expected to mediate the relationship between gender and perceived dominance. Future research should examine the effect of race in these interactions, as well as how this dynamic effects gender non-conforming persons.

The aim of this thesis is to describe the language of electronic communication ('netspeak') as one of the present trends of the development of English. The thesis is based on the hypothesis 'netspeak' represents an independent multimodal linguistic variety sharing some features with informal face-to-face conversation. For this purpose, the language of selected samples of the texts of English-speaking students of British universities obtained from the social network Facebook was studied. The qualitative and quantitative analysis of these data and their comparison with spoken form of standard English, namely with the spoken demographically sampled part of the British National Corpus, confirmed the hypothesis. ! Key words: netspeak, CMC, Facebook, emoticons, face-to-face communication, informal conversation

O objetivo desta dissertação é apresentar um estudo sobre o emprego de demonstrações em uma narrativa contada em língua de sinais brasileira (libras). Este trabalho parte da ideia de que a copresença de participantes na interação tem influência na maneira como a narrativa é expressa e interpretada (McCleary 2011; McCleary & Viotti 2014). A investigação dos elementos envolvidos na elaboração das demonstrações é feita a partir de uma perspectiva multimodal. Para tratar da multimodalidade em interações presenciais, tomei como base as propostas de Clark (1996) e Hutchins (2010), segundo as quais os participantes de uma interação precisam se coordenar para a realização de atividades conjuntas. Nessa perspectiva, demonstrar envolve crucialmente dois aspectos: i) a habilidade de se coordenar na imaginação conjunta dos elementos da narrativa, como os cenários, as personagens e suas ações, os eventos etc; e ii) o uso do corpo, de gestos de diferentes tipos e do espaço como ferramentas nesse ato imaginativo situado na interação. Para estudar demonstrações especificamente em discursos sinalizados, tomei como base Liddell (2003) e Dudis (2007), que analisaram demonstrações em discursos em língua de sinais americana (ASL), e McCleary & Viotti (2010, 2011, 2014), que analisaram narrativas em libras. A partir da aproximação entre os trabalhos desses autores, foi possível observar: i) as ocorrências de demonstrações em diferentes níveis discursivos; e ii) a relevância de considerar o nível do narrador nas análises de ocorrências de demonstração. A narrativa analisada, intitulada \"Bolinha de Ping Pong\", foi transcrita no software ELAN seguindo o modelo de transcrição proposto por McCleary, Viotti & Leite (2010). A análise trouxe evidências de que a demonstração é uma estratégia discursiva central em narrativas sinalizadas, e que contar histórias fluentemente envolve, em grande medida, a habilidade no uso de demonstração, integrada com outras estratégias narrativas. / This thesis aims at presenting a study of uses of demonstration in a narrative in Brazilian Sign Language (Libras). The study is based on the idea that the co-presence of the participants involved in any interaction influences the way in which the narrative is expressed and interpreted (McCleary 2011; McCleary & Viotti 2014). The analysis of the elements involved in the use of demonstrations along the narrative is based on a multimodal approach. In order to describe the multimodality in face-to-face interaction, I have used models put forward by Clark (1996) and Hutchins (2010). These authors suggest that participants in any interaction coordinate themselves to perform joint activities. According to that approach, demonstration crucially involves two aspects: i) the ability to coordinate the joint imagination of elements of the narrative such as scenarios, characters, actions, events, etc; and ii) the use of the body, different kinds of gesture and the space as tools during that construct the imaginative act in the interaction. For the study of demonstrations in signed discourses, specifically, I based my analyses on Liddell (2003) and Dudis (2007), who described the use of demonstration in discourses in American Sign Language, and on McCleary & Viotti (2010, 2011, 2014), who analyzed narratives in Libras. Based on these authors, it was possible to observe: i) the uses of demonstrations are different levels of narrative discourse; ii) the relevance of taking into account the narrator level to the analysis of uses of demonstration. The analyzed narrative entitled Ping Pong ball was transcribed using the software ELAN, following the model proposed in McCleary, Viotti & Leite (2010). The analysis implies that demonstration is a central discursive strategy in signed narratives, and that, to a great extent, fluency in signing stories involves the ability to use demonstrations, integrated with other narrative strategies.

This thesis is dedicated to exploring the potential of the 3D shape of the nasal region for face recognition. In comparison to other parts of the face, the nose has a number of distinctive features that make it attractive for recognition purposes. It is relatively stable over different facial expressions, easy to detect because of its salient convexity, and difficult to be intentionally cover up without attracting suspicion. In addition compared to other facial parts, such as forehead, chin, mouth and eyes, the nose is not vulnerable to unintentional occlusions caused by scarves or hair. Prior to undertaking a thorough analysis of the discriminative features of the 3D nasal regions, an overview of denoising algorithms and their impact on the 3D face recognition algorithms is first provided. This analysis, which is one of the first to address this issue, evaluates the performance of 3D holistic algorithms when various denoising methods are applied. One important outcome of this evaluation is to determine the optimal denoising parameters in terms of the overall 3D face recognition performance. A novel algorithm is also proposed to learn the statistics of the noise generated by the 3D laser scanners and then simulate it over the face point clouds. Using this process, the denoising and 3D face recognition algorithms’ robustness over various noise powers can be quantitatively evaluated. A new algorithm is proposed to find the nose tip from various expressions and self-occluded samples. Furthermore, novel applications of the nose region to align the faces in 3D is provided through two pose correction methods. The algorithms are very consistent and robust against different expressions, partial and self-occlusions. The nose’s discriminative strength for 3D face recognition is analysed using two approaches. The first one creates its feature sets by applying nasal curves to the depth map. The second approach utilises a novel feature space, based on histograms of normal vectors to the response of the Gabor wavelets applied to the nasal region. To create the feature spaces, various triangular and spherical patches and nasal curves are employed, giving a very high class separability. A genetic algorithm (GA) based feature selector is then used to make the feature space more robust against facial expressions. The basis of both algorithms is a highly consistent and accurate nasal region landmarking, which is quantitatively evaluated and compared with previous work. The recognition ranks provide the highest identification performance ever reported for the 3D nasal region. The results are not only higher than the previous 3D nose recognition algorithms, but also better than or very close to recent results for whole 3D face recognition. The algorithms have been evaluated on three widely used 3D face datasets, FRGC, Bosphorus and UMB-DB.
