Yes / Our motor actions normally generate sensory events, but how do we know which events were self generated and which have external causes? Here we use temporal adaptation to investigate the processing stage and generality of our sensorimotor timing estimates. Methodology/Principal Findings: Adaptation to artificially-induced delays between action and event can produce a startling percept¿upon removal of the delay it feels as if the sensory event precedes its causative action. This temporal recalibration of action and event occurs in a quantitatively similar manner across the sensory modalities. Critically, it is robust to the replacement of one sense during the adaptation phase with another sense during the test judgment. Conclusions/Significance: Our findings suggest a high-level, supramodal recalibration mechanism. The effects are well described by a simple model which attempts to preserve the expected synchrony between action and event, but only when causality indicates it is reasonable to do so. We further demonstrate that this model successfully characterises related adaptation data from outside the sensorimotor domain.

The importance of the aura, the metaphysical element that gives art, artifacts, and other objects of cultural heritage their authenticity, has been heavily contemplated ever since the publication of Walter Benjamin's "The Work of Art in the Age of Mechanical Reproduction." This thesis strives to add to this conversation and expand upon it by delving into the emergence of additive manufacturing, or what is more commonly known as 3D printing, and its relation to museums and other institutions that comprise the public humanities. This technology challenges the auratic properties of an exhibit by first digitizing it onto a computer by scanning it and then uploading this data to a 3D printer, which then proceeds to replicate the scanned exhibit down to incredibly fine details. For museums the possibility that 3D printed replicas, increasingly able to be indistinguishable from the original and capable of being produced in great numbers at ease, replacing their auratic exhibits is a very real possibility to consider. This thesis argues that some museums are responding by despatializing their exhibitions in order to uphold their auratic exhibits, while others are offsetting the potential loss by turning their exhibitions into tactile, multisensory experiences. Either option, which are not mutually exclusive, transforms the traditional museum. This thesis ultimately concludes that it's possible to reconcile the auratic exhibit with the 3D printed replica should these institutions properly adapt. Doing so will allow them to continue fulfilling their mission statements to preserve and promote the auratic exhibits well into the future. / Master of Arts / The emergence of 3D printing in recent years has brought with it many implications for not just society, but also the museums and other institutions that comprise the public humanities. Along with printing out objects designed entirely within a computer, 3D imaging and printing technology can easily process scanned objects that have been digitized onto a computer and then reproduce that object while accurately mimicking the specific features that once made it unique. As they increasingly improve in their ability to print with more and more materials, distinguishing the original from its copies from sight alone brings with it an existential dilemma for museums that rely on the authenticity of the original to draw visitors. If everyone could potentially have their own life-size copy of David thanks to a 3D printer, what fate awaits the original David? This thesis will detail this possible development and how exhibitions are responding. Arguing that some museums are in fact utilizing 3D printers outside the halls of their institutions in order to uphold their original collections, while others are offsetting the potential loss by embracing the reproducibility 3D printers provide to allow visitors to touch and interact with 3D printed copies in multisensory exhibitions. Either option, which are not mutually exclusive, transforms the traditional museum going experience. This thesis ultimately concludes that it’s possible to reconcile the original with a perfectly mimicked copy should these institutions properly adapt, allowing them to fulfill their missions to preserve and promote the originals well into the future.

The experiments reported within this thesis use psychophysical techniques to examine the factors which determine perceived multisensory timing in humans. Chapters 1 and 2 describe anatomical and psychophysical features of temporal processing, respectively, whilst Chapter 3 introduces the reader to psychophysical methods. Chapter 4 examines the relationship between two measures of sensory latency, reaction time (RT) and crossmodal temporal order judgment (TOJ). Despite task and attentional manipulations the two measures do not correlate, suggesting that they measure some fundamentally different aspect(s) of temporal perception. Chapter 5 examines the effects of adaptation to asynchronous stimulus pairs on perceived audiovisual (AV), audiotactile (AT) and visuotactile (VT) temporal order. Significant temporal shifts are recorded in all three conditions. Evidence is also presented showing that crossmodal TOJs are intransitive. Chapter 6 shows that concurrent adaptation to two sets of asynchronous AV stimulus pairs causes perceived AV temporal order to recalibrate at two locations simultaneously, and that AV asynchrony adaptation effects are significantly affected by observers' attention during adaptation. Finally, Chapter 7 shows that when observers are accustomed to a physical delay between motor actions and sensory events, an event presented at a reduced delay appears to precede the causative motor action. The data are well-described by a simple model based on a strong prior assumption of physical synchrony between motor actions and their sensory consequences.

Författare: Klara Johansson, Marina Johansson Handledare: Professor Bertil Hultén Examinator: Universitetslektor Leif V Rytting Kurs: Företagsekonomi III – Examensarbete inriktning detaljhandel och service management (kandidat) 15hp Problemformulering: Hur påverkas kundens rörelsemönster och köpbeteende i en butiksmiljö med hjälp av visuella stimuli samt auditivt stimuli? Syfte: Syftet med examensarbetet är att undersöka, analysera och klargöra huruvida kundens rörelsemönster och köpbeteende kan påverkas med hjälp av sensoriska stimuli. Vi vill med hjälp av en multisensorisk upplevelse, vita pilar samt ljudet av fågelkvitter, försöka påverka kundens vägval i butiken för att bidra till att denne ska uppmärksamma större del av butiksytan. Metod: Examensarbetet har utformats med ett deduktivt angreppssätt. Vi har gjort en kvantitativ analys med en experimentell ansats. En omfattande litteraturstudie har legat till grund för de hypoteser som formulerats, i syfte att svara på forskningsfrågan. Primärdata har samlats in genom sammanlagt 1347 observationer på Plantagen i Kalmar. Slutsats: En slutsats av arbetet är att kunderna påverkas till att följa visuella stimuli i form av pilar. Det är därmed möjligt att påverka kunden att se mer av butikens yta med hjälp av visuella stimuli. Vi kan även visa att tillsättning av auditivt stimuli och visuella stimuli påverkar köpbeteendet i form av tid spenderad i experimentzonen, men det behövs vidare forskning för att utreda i vilken grad påverkan sker.

A Study of how visual and auditory stimuli can influence the customer's movement patterns and buying behaviour in store. Authors: Klara Johansson, Marina Johansson Supervisor: Professor Bertil Hultén Ph.D. Examiner: Senior Lecturer Leif V Rytting Ph.D. Course: Business economies III – Retail and service management (C level) Issues: How are the customer's movement patterns and buying behaviour affected in store with the help of visual and auditory stimuli? Purpose: The purpose of this study is to investigate, analyse and clarify whether the customer's movement patterns and buying behaviour can be affected by means of sensory stimuli. With the help of sensory marketing, white arrows and bird song, we want to influence the customer's choice of direction in the store with the purpose of making the customer notice a wider part of the store. Methodology: The thesis has been designed with a deductive approach. We have done a quantitative analysis with an experimental approach. An extensive search for literature has been the basis of the hypotheses formulated, in order to answer the research question. Primary data were collected through a total of 1347 observations at Plantagen in Kalmar. Findings: A finding of this thesis is that customers are influenced to follow the visual stimuli by the means of white arrows. It is thereby possible to affect customers to notice a wider part of the store by the means of visual stimuli. We can also show that adding auditory stimuli and visual stimuli can affect the buying behaviour in the matter of time spent in the experimental zone, although further research is required to exam to which extent the impact occurs. Keywords: Sensory marketing, visual stimuli, auditory stimuli, in stores, movement patterns, multisensory, congruence

Notre travail s’inscrit dans une conception fonctionnaliste de la mémoire qui se donne pour objectif de décrire le fonctionnement de la mémoire plus que sa structure. Notre assise théorique est basée sur le modèle Act-in qui postule que la mémoire est représentée par un ensemble de traces multidimensionnelles. Ces traces comporteraient l’ensemble des dimensions d’une expérience (e.g., motrices, sensorielles, émotionnelles). Pour rendre compte de l’émergence des connaissances, ce modèle repose sur deux mécanismes : l’activation et l’intégration. Notre travail avait pour objectif de spécifier les relations fonctionnelles entre activation et intégration à travers les mécanismes perceptifs et les mécanismes mnésiques. Nous avons également proposé un mécanisme d’interaction, permettant de rendre compte de la formation des traces sensorielles en mémoire. Comme le modèle Act-in conçoit les traces en mémoire comme étant multidimensionnelles, nous avons étudié les différentes relations entre mécanismes d’intégration, interaction et activation via le prisme de la multimodalité. Ce travail s’est organisé autour de deux grands axes expérimentaux, un premier tourné vers l’intégration en perception et l’autre vers l’intégration en mémoire.Dans un premier axe, nous avons introduit la notion d’interaction multimodale pour rendre compte des relations entre modalités sensorielles dans des tâches perceptives. Nous avons montré que lorsque des interactions sensorielles étaient systématiquement répétées, les performances de sujets étaient meilleures que celles observées dans un contexte multimodal dans lequel les modalités sensorielles n’entretenaient pas de lien. Nous avons mesuré à l’aide d’un outil mathématique, le Race Model, le gain multi-sensoriel dans diverses conditions. Nous avons montré que le Race Model mesurait un gain multi-sensoriel essentiellement lorsque la tâche n’impliquait pas de processus mnésiques (i.e., détection). Selon nous, cela montre que cet outil mathématique est plus sensible à l’interaction multimodale, lorsque les composants sensoriels ne sont pas intégrés en mémoire.Dans un second axe, nous avons développé un paradigme expérimental permettant de mesurer les effets d’un encodage sensoriel sur une récupération ultérieure (i.e., catégorisation, reconnaissance et rappel libre). Nous avons montré qu’une association multimodale congruente lors d’un encodage (e.g., image de chien et aboiement du chien) améliorait significativement les performances dans diverses tâches de mémoire. Selon nous, l’activation des dimensions auditives associées au sein de la trace explique cette facilitation lors de la récupération. Nous avons également montré qu’une association multimodale non congruente lors de l’encodage (e.g., image d’un chien et bruit blanc) perturbait la récupération en mémoire à long terme. Ce résultat apporte un argument supplémentaire en faveur des modèles de mémoire qui postulent que les connaissances sont avant tout sensorielles.Pour résumer, ce travail a permis dans un premier temps de proposer un mécanisme d’interaction multimodale nécessaire à l’intégration des composants sensoriels en mémoire. Dans un second temps, nous avons montré que des modalités sensorielles associées lors de l’encodage pouvait être réactivées ultérieurement et faciliter le traitement uniquement si les modalités sensorielles étaient sémantiquement congruentes. Ce résultat renforce la conception d’une mémoire organisée autour de connaissances avant tout sensorielles.Enfin, les résultats que nous obtenons suggèrent que la mémoire et la perception partagent des traitements communs car un trait perceptivement absent peut influencer un trait perceptivement présent et réciproquement. Cela nous permet d’envisager une relation horizontale entre mémoire et perception et remet en question la conception traditionnelle top-down des liens entre mémoire et perception. / Our conception of memory has the aim to describe the memory process more than the memory architecture. Our theoretical approach is based on the Act-in model, postulating that memory is represented by a multidimensional set of traces. These traces should include all dimensions of an experience (e.g., sensory-motor and emotional components). This model relies on two mechanisms (i.e., activation and integration) in order to reveal the emergence of knowledge. The aim of this work was to specify the functional relationships between activation and integration through memory and perception mechanisms. We also proposed a mechanism of interaction, to understand the formation of sensory memory traces. The model Act-in is composed by multidimensional memory traces. Thus, we studied the relationship between integration, interaction and activation through multimodality. This work was organized around two main axis. On one hand perceptual integration and on the other hand the memory integration.In the first axis, we have introduced the concept of multimodal interaction to show the relationship between sensory modalities in perceptual tasks. Our results revealed that when sensory interactions were systematically repeated, the performance of subjects were better than those observed in a context in which multimodal sensory modalities did not maintain a link. We measured using a mathematical tool, the Race Model, multi-sensory gain under various conditions. We have shown that the Race Model measured multi-sensory gain, mainly when the task did not involve memory processes (i.e., detection). This mathematical tool seems to be more sensitive to multimodal interaction, when the sensory components are not integrated into memory.In the second axis, we used an experimental paradigm to measure the effects of sensory encoding on subsequent retrieval tasks (i.e., categorization, recognition and free recall). Our results showed that a congruent multimodal association at encoding (e.g., image of dog and the dog barking) improved performance in various memory tasks. It seems that the activation of the sensory dimensions could explain the facilitation during retrieval. Moreover, an incongruent multimodal association at encoding (e.g., image of a dog and white noise) disturbed performance from retrieval in long-term memory. This result provides a further argument supporting sensory-based memory model.In summary, we propose a multimodal interaction mechanism for the integration of sensory components in memory. Secondly, we have shown that sensory modalities associated during encoding could be reactivated later and facilitate the processing only when the sensory modalities were semantically congruent. This result improves the assumption that memory is sensory-based.Finally, theses results suggest that memory and perception share common features. The reactivation of a sensory dimension can influence the perceptual dimension processing and vice versa. This allows us to consider a horizontal relationship between memory and perception. In such case, the traditional relationship between memory and perception, as assumed to be top-down, could be questioned.

A integração audiovisual é capaz de melhorar a performance e a aprendizagem unissensorial. Esta integração ocorre mesmo quando uma das informações sensoriais não é consciente ao indivíduo, e.g. informação semântica auditiva pode impactar percepção visual inconsciente. No âmbito da percepção visual não consciente, o fluxo da informação fica restrito ao início do processamento cortical, não alcançando áreas de alta ordem, como a rede parietal-frontal. Considerando que as interações multissensoriais no córtex podem ocorrer desde estágios iniciais do processamento, levantamos a hipótese que a apresentação de estímulos visuais não conscientes pode beneficiar a aprendizagem auditiva de percepção de notas musicais. Neste estudo, testamos sujeitos em um paradigma de aprendizagem auditiva. Os indivíduos tinham como tarefa identificar seis notas diferentes separadas por 50 cents, ou ¼ de tom entre si. Os grupos foram divididos de acordo com o treinamento: auditivo (A), Auditivo + visual não consciente congruente (AV), e Auditivo + visual não consciente incongruente (AVi). Eles passaram por testes pré- e pós-treinamento de escolha forçada dentre seis alternativas somente com informação auditiva. Registramos dados de Eletroencefalografia (EEG) ao longo do experimento. A performance foi calculada por meio do Desvio Médio Absoluto das respostas com relação às notas corretas. Resultados comportamentais mostraram que o grupo AV não somente teve uma melhor performance durante o treinamento, quando a informação visual não consciente estava presente, como também apresentou um maior efeito do treinamento (melhora de pré- para pós-treinamento). Ambos os controles não diferiram entre si. Também mostramos que estes efeitos são devidos às notas da extremidade da escala. Os resultados de EEG mostram que a banda theta tem um papel fundamental na melhora da performance através do aumento da sincronização em áreas centrais e temporais, e da conectividade funcional entre córtices visuais e auditivos. Estes resultados são uma demonstração que asinterações multissensoriais ocorridas sem consciente são fortes o suficiente para aumentar a aprendizagem auditiva. Concluimos também que a conectividade funcional entre áreas corticais de processamento inicial aumenta depois de poucos minutos de treinamento. Além disso, esta tese levanta novas possibilidades para protocolos de aprendizagem perceptual auditiva, especialmente aqueles aplicado para aprendizagem de reconhecimento de notas musicais / Audiovisual integration may improve unisensory perceptual performance and learning. Interestingly, this integration may occur even when one of the sensory modalities is not conscious to the subject, e.g., semantic auditory information may impact nonconscious visual perception. Studies have shown that the flow of nonconscious visual information is mostly restricted to early cortical processing, without reaching higher-order areas, such as the parieto-frontal network. Thus, because multisensory cortical interactions may already occur in early stages of processing, we hypothesized that nonconscious visual stimulation without semantic information might facilitate auditory pitch learning. In this study we used a pitch learning paradigm, in which individuals had to identify six pitches in a scale with constant intervals of 50 cents. Subjects were assigned to one of three training groups: the test group (Auditory + congruent unconscious visual, AV), and two control groups (Auditory only, A, and Auditory + incongruent unconscious visual, AVi). Auditory-only tests were done before and after training in all groups. Electroencephalography (EEG) was recorded throughout the experiment. Results show that the test group (AV, with congruent nonconscious visual stimuli) performed better during the training, and showed a greater improvement from pre- to post-test. Control groups did not differ from one another. Changes in the AV group were mainly due to performances in the first and last pitches of the scale. We also observed consistent EEG patterns associated with this performance improvement in the AV group, especially higher theta-band synchronization among central and temporal areas, and stronger theta-band functional connectivity between visual and auditory cortices. Therefore, we show that nonconscious multisensory interactions are powerful enough to boost auditory perceptual learning, and that increased functional connectivity between early visual and auditory cortices after training might play a role in this effect. Moreover, weprovide a methodological contribution for future studies on auditory perceptual learning, particularly those applied to relative and absolute pitch training

Die sensorischen und hedonischen Eigenschaften von Essen sind wichtige Einflussfaktoren für die Nahrungsauswahl und –aufnahme. Was macht die Anziehungskraft von Nahrungsreizen aus? Die sensorischen und hedonsichen Eigenschaften von Nahrungsreizen werden mit allen Sinnen, oftmals sogar gleichzeitig, verarbeitet. Nahrungswahrnehmung ist damit ein mutlisensorisches Phänomen. Der Geruch, der Anblick, der Tasteindruck oder Geräusche können bereits vor der Nahrungsaufnahme wahrgenommen werden und Erwartungen hinsichtlich des Geschmacks auslösen. Diese prä-ingestiven Wahrnehmungseindrücke spielen daher auch eine maßgebliche Rolle bei der Entstehung von Verlangen und Gelüsten. Während der Nahrungsaufnahme, beim Kauen und Schlucken, spielen die chemischen Sinne, Schmecken und Riechen, eine besondere Rolle. Der Gesamtsinneseindruck aus den chemischen Sinneskanälen wird auch als Flavor bezeichnet. Wobei angemerkt sein soll, dass auch nicht-chemische Sinne, Sehen, Hören und Tasten, in die Flavordefinition einbezogen werden können. Zweifelsohne stellt die Nahrungsaufnahme ein komplexes Verhalten dar, das perzeptuelle, kognitive und Stoffwechselprozesse gleichermaßen umfasst. Die vorliegende Habilitationsschrift widmet sich der Untersuchung der neurokognitiven Mechanismen der visuellen, gustatorischen und flavour Wahrnehmung von Nahrungsobjekten und umfasst Untersuchungen zur Vulnerabilität der neuronalen Repräsentationen durch kontextuelle Reize. Zusammenfassend schließt die Arbeit mit der Feststellung, dass ein umfassendes Verständnis der psychophysiologischen Mechanismen der sensorischen und hedonischen Verarbeitung von Nahrungsreizen über alle Sinne die perzeptuelle Grundlage für nahrungsbezogenes Urteilen und Entscheiden darstellt. / What characterizes food and makes it so tempting? Sensory and hedonic information about food is conveyed by all senses, activated more or less simultaneously, having led to the notion that food perception is a multisensory experience. The smell, sight, touch or sound of a food can be experienced before ingestion and elicit expectations about the "taste" of that food based on previous encounters. It is, therefore, not surprising that these so-called pre-ingestive sensory experiences play a role in the formation of cravings and the elicitation of appetitive responses. Only during consumption, the chemical senses, smell, taste and oral touch and irritation, are experienced in the oral cavity as food is masticated and swallowed and gives rise to the overall experience commonly referred to as taste. While the term taste is, strictly speaking, incorrect as it does not refer to the gustatory perception, many languages including German lack an appropriate term for the holistic flavor experience arising from the food-induced stimulation of the chemical senses, gustation, olfaction and oral somatosensation in a minimalist interpretation, or, in a broader sense, of all our senses, including hearing and vision. Undoubtedly, feeding behavior is characterized by a complex interplay of perceptual, cognitive and metabolic processes and research on the mechanisms by which these processes regulate food intake behavior is only in its infancy. In this thesis, I present a series of studies aiming to elucidate the cortical representations of the visual, gustatory and flavor components of food objects along with evidence for the vulnerability of these presentations to contextual information. Together, I reckon that an understanding of the psychophysiological mechanisms of the sensory and affective processing of food objects mediated by our senses, seeing, smelling, tasting, feeling and hearing, represents the perceptual basis of food-related decision making.

Herta Müller represents physical suffering and repression in her works, often reflecting on the regime of Nicolae Ceaușescu, and her constant interest in language and reflexivity towards writing have led her to develop sophisticated metaphors that she uses to illuminate language and its functioning under such subjugation. With reference to her fiction and non-fiction, I demonstrate how she uses concrete ideas to understand linguistic phenomena. She evokes injury, destruction, force, life, space, touch, silence, and other bodily experiences to make sense of language in the condition of suffering from social oppression. Drawing on conceptual metaphor theory within the framework of cognitive literary studies, I argue that Müller both relies on and estranges the ways in which people speak and think about language. Language is imagined differently depending on the circumstances and in close relationship with various sensory experiences. The complexity of the relationship between language and thought problematises the process of metaphor building and makes it difficult to identify its key aspects across different contexts and sensory modalities. Müller’s tropes are easy to experience, but difficult to analyse. The idea of language does not exist as a stable concept and is regularly reimagined in her texts; but its meaning is not arbitrary and depends on bodily experience. While Müller evokes such experience to understand language in the condition of suffering, she can also use linguistic concepts to elucidate more abstract ideas. Language can be regarded as an abstract or concrete phenomenon depending on the relevant bodily, linguistic, and cultural contexts. This project contributes to the study of Müller’s poetics as well as to the literary critical interpretation of embodied cognition, and develops the use of conceptual metaphor theory for literary analysis. It also seeks to develop understanding of the role of bodily experience in the metaphorical conceptualisation of language.

La rééducation fonctionnelle classique comprend des séances thérapeutiques, des exercices à domicile et des mouvements avec ou sans l'aide de thérapeutes. Cette approche classique souffre de nombreuses limitations, en raison de l’incapacité de l’expert à suivre les séances à domicile du patient et du manque de motivation du patient pour répéter les exercices sans retour. Les jeux sérieux ont été présentés comme une solution à ces problèmes. Premièrement, des exergames ont été développés à l’aide d’une méthodologie de codesign, où patients, experts et développeurs ont pris part aux procédures de conception. Le capteur Kinect a été utilisé pour capturer la cinématique en temps réel au cours de l’exercice. Ensuite, une fusion de données a été étudier entre le capteur Kinect et les unités de mesure inertielles, afin d’augmenter la précision de l’estimation de l’angle des articulations, à l’aide d’une approche système de systèmes. Le système a été évalué par des patients avec différentes pathologies au cours de multiples campagnes d'évaluation. Les résultats obtenus montrent que les jeux sérieux peuvent être une solution pour des pathologies spécifiques. En outre, les experts ont été convaincus de la pertinence clinique de ce dispositif et ont estimé que les données proposées étaient suffisantes pour évaluer la situation du patient. La mise en place de tels systèmes maximiserait l’efficacité du programme de réadaptation. D'autre part, ce système permettrait également de réduire les limitations actuellement présentes dans les programmes de rééducation classiques, permettant aux patients de visualiser leurs mouvements et aux experts de suivre l'exécution de l'exercice à domicile. / Conventional musculoskeletal rehabilitation consists of therapeutic sessions, home exercise assignment, and movement execution with or without the assistance of therapists. This classical approach suffers from many limitations, due to the expert’s inability to follow the patient’s home sessions, and the patient’s lack of motivation to repeat the same exercises without feedback. Serious games have been presented as a possible solution for these problems. This thesis was carried out in the eBioMed experimental platform of the Université de technologie de Compiège, and in the framework of the Labex MS2T. The aim of this thesis is to develop a real-time, serious gaming system for home-based musculoskeletal rehabilitation. First, exergames were developed, using a codesign methodology, where the patients, experts and developers took part in the design and implementation procedures. The Kinect sensor was used to capture real-time kinematics during each exercise. Next, data fusion was implemented between the Kinect sensor and inertial measurement units, to increase the accuracy of joint angle estimation, using a system of systems approach. In addition, graphical user interfaces were developed, for experts and patients, to suit the needs of different end-users, based on the results of an end-user acceptability study. The system was evaluated by patients with different pathologies through multiple evaluation campaigns. Obtained results showed that serious games can be a good solution for specific types of pathologies. Moreover, experts were convinced of the clinical relevance of this device, and found that the estimated data was more than enough to assess the patient’s situation during their home-based exercise sessions. Finally, during these three years, we have set the base for a home-based rehabilitation system that can be deployed at home or in a clinical environment. The implementation of such systems would maximize the efficiency of rehabilitation program, while saving the patient’s and expert’s time and money. On the other hand, this system would also reduce the limitation that are currently present in classical rehabilitation programs, allowing the patients to visualize their movements, and the experts to follow the home exercise execution.
