Despite its great complexity, a great deal is known about the organization and information-processing properties of the visual system. However, the neural correlates of visual awareness are not yet understood. By studying patients with blindsight, the primary visual cortex (V1) has attracted a lot of attention recently. Although this brain area appears to be important for visual awareness, its exact role is still a matter of debate. Interactive models propose a direct role for V1 in generating visual awareness through recurrent processing. Hierarchal models instead propose that awareness is generated in later visual areas and that the role of V1 is limited to transmitting the necessary information to these areas. Interactive and hierarchical models make different predictions and the aim of this thesis is to review the evidence from lesions, perceptual suppression, and transcranial magnetic stimulation (TMS), along with data from internally generated visual awareness in dreams, hallucinations and imagery, this in order to see whether current evidence favor one type of model over the other. A review of the evidence suggests that feedback projections to V1 appear to be important in most cases for visual awareness to arise but it can arise even when V1 is absent.

This thesis details an investigation into the neural correlates of visual awareness. Extant data acquired with whole brain imaging techniques suggest that being visually aware is associated with a widespread pattern of neural activity that includes the activation of frontal and parietal areas in addition to more specialised local processors (i.e. brain areas that process for specific sorts of information). However, this idea could not be unequivocally accepted because the relevant studies failed to control for or minimise the influence of attentional shifts and/or cognitive demands, two variables that have been known to engage frontal and parietal areas similar to those observed in studies of awareness. As such, it was initially impossible to determine whether the observed frontal and parietal activity was associated with awareness per se or instead with related but distinct processes. Here, in a series of functional magnetic resonance imaging experiments, the natural correlates of visual awareness were probed by manipulating the focus of attention. Behavioural studies have demonstrated that information not given the benefit of attentional processing is not available to conscious awareness. In the main experiments here, subjects viewed two streams of continuous (and equivalent) visual events, paying attention to only one stream and ignoring the other. Behavioural tests conducted confirmed that attended visual information was seen and remembered better than unattended information. Correspondingly, contrasting the neural activity associated with attended visual events with that associated with unattended visual events revealed a large-scale distributed pattern of neural activity (that included frontal and parietal foci), even when the influence of cognitive demands and spatial shifts of attention were controlled for or minimised. This pattern of activity was observed under different experimental conditions and with different stimulus sets, hinting at its generality. Further experiments ruled out the possibility that these results were due to novelty detection or inhibitory processes that operate when having to deal with multi-object visual displays. Additionally, it was found that these frontal and parietal areas where likewise sensitive to increases in cognitive demand, suggesting a strong link between awareness and problem solving. These findings are discussed and evaluated with reference to the notion of a global workspace that is proposed to support conscious, adaptive control of thought and behaviour.

This thesis investigated the role of cortico-cortical interactions and the role of striate cortex (VI) in human visual awareness in both normal subjects and the blindsight subject GY. In Chapter 3, the critical time windows of VI and V5/MT activity in awareness of moving visual stimuli were compared using transcranial magnetic stimulation (TMS). The results demonstrate the importance of backprojections from V5/MT to VI in awareness of real motion stimuli. In Chapter 4, the role of VI in conscious perception of moving phopshenes induced by stimulation of V5/MT was studied. By varying the activation level of VI, it is shown that the amount of activity in VI determines whether activity in V5/MT reaches awarereness. Furthermore, the activity in V5/MT influences the information content in VI, but it is VI that determines whether that information reaches awareness. In chapter 5, it is reported that the blindsight subject GY can experience visual sensations, elicited by TMS, in his blind field. Importantly, such blind field percepts (phosphenes) could only be induced when GY's contralesional extrastriate area V5/MT was stimulated in close temporal proximity with the ipsilesional V5/MT. Stimulation of his ipsilesional V5/MT also altered to appearance of phosphene induced from the intact VI, but did not induce a blind field percept. The necessity of the contralesional stimulation in eliciting phosphenes from extrastriate cortex points to the importance of VI in visual awareness. In chapter 6, the role of FEF in exerting top-down influences on the extrastriate visual cortex prior to eye movement preparation was studied. It was established, using TMS, that activity in the human frontal eye fields has a direct effect on the sensitivity of extrastriate visual area V5/MT, and that the spatial organisation of this top-down effect is lateralised in the human brain.

The neuronal underpinnings of visual awareness has recently become the primary question of interest for many researchers, with many theories suggesting distinct mechanisms. The aim of this thesis was to test predictions of the low-level modular theory of visual awareness. This modular view is encapsulated in the 'microconsciousness' framework (Zeki & Bartels, 1999) in which each visual processing system, such as that for colour, is capable of generating a conscious correlate autonomously in parallel across space, within each of the different functionally specialised areas of the visual brain, and across time, with different attributes perceived at different times. Given the scope of this topic, we approached it from three diverse angles: (1) Two psychophysical experiments investigated temporal aspects of visual perception - in particular these addressed the issue of whether the timing of awareness is an 'online* phenomenon rather than integrated into a temporal buffer zone prior to awareness. We measured the relative perceptual times of different magnitudes of direction changes and investigated the 'flash-lag' effect (Nijhawan, 1994) and related illusions of positional localisation. (2) The first two fMRI experiments examined the necessity of frontal and parietal areas for visual awareness in the context of bistable figures, combined with dynamic causal modelling (Friston et al., 2003), and perception outside the focus of attention. (3) We looked to extend the concept of modularity of awareness to that of 'access consciousness', that is the ability to give a report of a conscious experience (Block, 1996), in addition to the previous studies on phenomenal consciousness. To this end, we combined psychophysics with fMRI to investigate the interaction between report modality and visual perception. We conclude that the low-level modular theory of stands up to direct tests of its predictions and remains a viable theory of visual awareness.

This thesis explores the subjective experience of targets in rapid serial visual presentation (RSVP), an experimental paradigm where visual stimuli are displayed in rapid succession. In RSVP, items appear on the screen so briefly that not every item in the stream can be encoded reliably. Thus, it allows observation of conscious experience at the fringe of perception. The Attentional Blink (AB) - an effect in which an RSVP target is likely to be missed if it follows a fully processed first target - has been used in order to manipulate the accuracy of item identification by varying the target separation and presentation speed. The main focus of studies using RSVP presentation to make inferences about conscious perception has been the question of whether conscious perception is all-or-none or gradual. We initially present some thoughts on the suitability of the AB paradigm for answering this question. Not much is known about the effect of different variables in the paradigm on subjective experience, and it is possible that AB mechanisms affect experience quite differently from other paradigms, limiting the generalisability of findings derived from work within the AB paradigm. Based on this, we follow two lines of evidence: First, we explore the possibility of finding gradations in subjective visibility of targets measured on ratings scales and in the response of the electroencephalogram using a simple single target RSVP. Second, we investigate the effect of target separation and perceived order on this subjective experience in the AB paradigm. Our results indicate that items in single-target RSVP can be perceived in a graded manner, with possible indications of a non-linear jump in brain activity between not-seen and seen items. Regarding subjective experience when separation of two targets is varied, we find a disconnect between accuracy and visibility of the second target when in close proximity to the first, showing relatively low subjective experience considering the high report accuracy. Target separation also affects the number of order confusions, which we find to reduce target visibility under specific conditions. These results add to our understanding of how targets are perceived in RSVP and have implications for research into conscious perception.

The studies presented in this thesis address current issues in visual attention and awareness research. The first three experimental chapters investigate saccadic remapping of location and orientation information, with a particular focus on saccadic remapping in hemianopia. The results suggest that residual visual abilities in the blind field are necessary in order for a stimulus to be remapped from the blind to the sighted visual field. The results also suggest that remapping underpins our ability to maintain attention at specific spatiotopic locations across a series of saccades. Further evidence from both hemianopic and neurologically intact participants suggest that some orientation information is remapped across saccades. The second three experimental chapters investigate binocular rivalry in previously unstudied paradigms. The results show that the established face dominance and emotion dominance effects in binocular rivalry persist when the stimuli are viewed in peripheral vision. The results also suggest that a stable image presented in the opposite hemifield from the rival pair does not affect the perceived dominance of the separate images within the rival pair, but that the percepts in the rival pair tend to synchronise with those of a second rival pair presented in the opposite hemifield. Using Diaz-Caneja stimuli (half of each image presented to each eye) the results of the final experiments suggest a combination of eye- and object-dominance mechanisms in binocular rivalry in both the intact and the split-brain.

Many event-related potential (ERP) studies have tried to find out which brain processes are responsible for the subjective experience of seeing. The contribution of these studies has been crucial in order to identify the temporal and spatial dynamics of visual awareness. The negative difference wave named visual awareness negativity (VAN), observed around 200 ms after the stimulus onset, has been claimed by many as a plausible candidate for reflecting the processes correlating with conscious visual perception. Other studies argue instead that only the P3 wave, a positive wave observed around 300-400 ms, correlates with visual awareness. The aim of the present study was to shed light on the issue of the presence of VAN even when using an experimental procedure that allows to dissociate the ERP correlate of subjective awareness from those of unconscious perception, allowing a separate analysis. Data from 24 participants was collected in the present study. The experimental framework included a forced-choice localization task of a low-contrast stimulus, followed by the subjective rating of awareness. The results of the study support the idea that the VAN is the earliest electrophysiological correlate of subjective visual awareness and that the phenomenon of visual awareness emerges early in the visual area.

uCom enables remote users to be visually aware of each other using "spatial displays" - live views of a remote space assembled according to an estimate of the remote space's layout. The main elements of the system design are a 3D representation of each space and a multi-display physical setup. The 3D image-based representation of a space is composed of an aggregate of live video feeds acquired from multiple viewpoints and rendered in a graphical visualization resembling a 3D collage. Its navigation controls allow users to transition among the remote views, while maintaining a sense of how the images relate in 3D space. Additionally, the system uses a configurable set of displays to portray always-on visual connections with a remote site integrated into the local physical environment. The evaluation investigates to what extent the system improves users' understanding of the layout of a remote space.

We can distinguish different forms of attention, for example paying attention to what we are thinking about, paying attention to what we hear, and paying attention to what we see or otherwise visually experience. This thesis is concerned with the form of attention paid to what we visually experience – visual attention. A natural way to think of visual attention is as sufficient for visual awareness: visually attending to an object is sufficient for being visually aware of it. (Plausibly, the relationship is closer. Visual attention is a way of being visually aware.) But we shouldn’t think of visual attention as necessary for visual awareness: we can be visually aware of objects that we are not visually attending to. In this thesis I provide a novel defence of the pre-theoretical conception of visual attention as sufficient, but not necessary, for visual awareness. Some psychologists have interpreted evidence, in particular from experiments involving subjects with blindsight, as proof that visual attention to an object is possible in the absence of any visual awareness of it. I argue we should not think of these results as proving that attention is not sufficient for awareness, but instead see them as motivation for a distinctively philosophical inquiry into the role of visual attention. I examine different explanations of the significance of visual attention for thought and action, ending with my own. Other psychologists have claimed, on the basis of experimental data, that visual attention is necessary for visual awareness. I argue this is inconsistent with the phenomenology of visual experience, and with other experimental data. I conclude that visual attention is sufficient but not necessary for visual awareness.

Given capacity limits, the visual system must prioritize the processing of sensory inputs that are most critical to successful interactions with the environment. Neurocognitive theories suggest that humans have evolved mechanisms that operate without awareness that selectively prioritize threatening stimuli in subsequent allocation of processing resources and access to awareness. Evidence for this ‘standard hypothesis’comes from paradigms that dissociate visual input from awareness. This thesis combines a narrative review, a meta-analytic review and three empirical studies to examine the extent to which emotionally salient stimuli are prioritized in the absence of awareness. A general introduction and review of the literature is provided in Chapter 1. The meta analysis of previous literature (Chapter 2) reveals that evidence for an unconscious processing bias for threat isundermined by insufficiently rigorous awareness measures and inadequate control of low-level confounds. Chapter 3 reveals that autonomic arousal and attentional orienting to visual threats are eliminated under conditions where observers are objectively unaware of stimuli. Chapter 4 reveals that prioritized processing of fearful faces is parsimoniously explained by effective contrast: the relationship betweentheir Fourier spectrum and the contrast sensitivity function. Importantly, this explanation does not require or involve unconscious processing mechanisms that are sensitive to threat. Chapter 5 reveals that prioritized processing of emotional face stimuli is restricted to conditions of awareness, and may be parsimoniously explained by simple low-level variability between emotional and neutral face stimuli. Previous and present findings and analyses are considered together in the discussion (Chapter 6). It is concluded that evidence for emotion-sensitive visual processing that operates without awareness is weak and that uncritical acceptance of the standard hypothesis is premature.

There is a need to understand large and complex datasets to provide better situa- tional awareness in-order to make timely well-informed actionable decisions in critical environments. These types of environments include emergency evacuations for large buildings, indoor routing for buildings in emergency situations, large-scale critical infrastructure for disaster planning and first responders, LiDAR analysis for coastal planning in disaster situations, and social media data for health related analysis. I introduce novel work and applications in real-time interactive visual analytics in these domains. I also detail techniques, systems and tools across a range of disciplines from GPU computing for real-time analysis to machine learning for interactive analysis on mobile and web-based platforms.

A visual analytics process to detect encounters between vessels from ship position data is developed in this thesis. An archive of historical position records is pre-processed and filtered to provide input for an encounter detection algorithm. The algorithm arranges the position records into a set of sorted lists (SSL) so that only a minimum number of records need to be compared. The algorithm performs a single sweep over the record set to arrange it into a SSL and simultaneously find the encounters. To avoid problems due to discrete sampling, an interpolation of the data is performed when the sampling is too sparse. To accommodate large data sets, a divide-and-conquer approach using a sliding spatial window is developed. In post-processing, the elementary encounters are grouped into composite encounters by collecting elementary encounters occurring between the same vessels. Additionally, the composite encounters are input into a visual analytics tool where each composite encounter is represented as a layer on a map. Patterns of life analysis and investigations of potential anomalous activity are performed by zooming in on encounter areas of interest. The development of a visual analytics process to identify vessels of interest is the significant result of this thesis.

In this thesis, a constraint-aware visual servoing control law is proposed. The control law is designed for a robot manipulator with an uncalibrated camera mounted on its end-effector. This control law allows the robot to execute large, collision-free motions with closed-loop positional accuracy. A reference image visually describes the desired end-effector position with respect to a target object whose location is initially unknown. The control law uses this reference image with online feedback from the camera to direct the trajectory of robot towards the completion of the positioning task. The control law generates feasible and realistic robot trajectories that respect the robot's joint position and velocity limits, even in the presence of large control gains. The control law also explicitly keeps the target object within the camera's field of view to provide uninterrupted visual feedback. The control law avoids potential whole-arm collisions with workspace obstacles via planning and control strategies. The visual servoing control law is implemented in a nonlinear model predictive control framework, using an estimated model of the eye-in-hand configuration and an estimated location of the target object. Two methods of approximating the object's location for joint-space path planning are demonstrated in simulations and experiments. The first uses homography estimation and decomposition on an un-modelled object. The second uses an extended Kalman filter with a prior object model to improve robustness against image noise and disturbances. Two planning and control strategies are presented. The first strategy uses an offline plan-then-servo approach that integrates probabilistic roadmaps with visual servoing. A method to construct paths between two robot configurations that keep the target object within the camera's field of view is demonstrated, allowing feasible transitions from planned motion to visual servoing. A method to address pose uncertainty to ensure collision-free, closed-loop motion is statistically tested with multiple positioning tasks. The second strategy uses an online iterative plan-and-servo approach that dynamically updates its estimate of the collision-free space while visual servoing. Experiments using an uncalibrated eye-in-hand platform demonstrate the ability of the visual servoing control law to achieve closed-loop positioning via collision-free trajectories, even when the object location is highly uncertain.

The thesis presents a novel situationally-aware multimodal spoken language system called Fuse that performs speech understanding for visual object selection. An experimental task was created in which people were asked to refer, using speech alone, to objects arranged on a table top. During training, Fuse acquires a grammar and vocabulary from a "show-and-tell" procedure in which visual scenes are paired with verbal descriptions of individual objects. Fuse determines a set of visually salient words and phrases and associates them to a set of visual features. Given a new scene, Fuse uses the acquired knowledge to generate class-based language models conditioned on the objects present in the scene as well as a spatial language model that predicts the occurrences of spatial terms conditioned on target and landmark objects. The speech recognizer in Fuse uses a weighted mixture of these language models to search for more likely interpretations of user speech in context of the current scene. During decoding, the weights are updated using a visual attention model which redistributes attention over objects based on partially decoded utterances. The dynamic situationally-aware language models enable Fuse to jointly infer spoken language utterances underlying speech signals as well as the identities of target objects they refer to. In an evaluation of the system, visual situationally-aware language modeling shows significant , more than 30 %, decrease in speech recognition and understanding error rates. The underlying ideas of situation-aware speech understanding that have been developed in Fuse may may be applied in numerous areas including assistive and mobile human-machine interfaces.

Med detta kandidatarbete vill vi uppmärksamma och förmedla hållbarhet, med fokus på konsumtion och plastnedskräpning i haven. Kandidatarbetet kommer löpa ut i en gestaltning som kommer befinna sig i ett fysiskt rum. Det fysiska rummet är ett fikarum och befinner sig på marinmuséumet i Karlskrona, vilket även är våran externa samarbetspart.Vi anser att det är viktigt att skriva om konsumtion och plastnedskräpning i hav eftersom det har en förödande påverkan på mänskligheten och för våran planet. Gestaltningen i kandidatarbetet kommer ta stöd utav perspektivet X for change. Metoder och idégenerering metoder som hjälpt vårt arbete framåt är brainstorming, moodboard, mindmaps och prototyper. Vi valde dessa metoder eftersom vi ansåg att detta kunde ge största möjliga potential för arbetet. I slutändan har vi en gestaltning som löpt ut genom många olika beslut och selektioner. Vi använder en teknik som kallas double exposure 3d som vi placerat på en av väggarna i rummet. Double exposure 3d betyder att man med hjälp av ett par “gamla” 3d glasögon, som har en blå och en röd sida, kan filtrera bort olika färgkanaler som då resulterar i två olika bilder, men som samtidigt är en hel. Vi har gjort två illustration av plastnedskräpning där ena läggs på den röda sidan och den andra på blåa sidan. Detta för att representera nutiden och hur framtiden kommer att se ut om vi fortsätter med våran ohållbara konsumtion och nedskräpning. Illustrationen är fiktionell och är endas en representation om hur världen skulle kunna se ut i framtiden. Väggen kommer även att stödjas av informativa posters med bland annat förslag på vad en individ kan bidra till.
With this bachelor thesis we want to raise awareness and to convey sustainability, with a focus on consumption and plastic littering in the sea. This bachelor thesis will result in a design that will be in a physical room. The physical room is a breakroom and is located in the Naval museum in Karlskrona, which is also our external partner. We believe that it is important to write about consumption and plastic littering in the sea because it has a devastating impact on humanity and our planet. The design that this bachelor thesis will produce will be supported by the design perspective X for Change. Methods and idea generating methods that helped our work move forward are brainstorming, moodboard, mindmaps and prototypes. We chose these methods because we consider that it could provide the greatest possible potential for the work. In the end we have a design created through many different decisions and selection. We use a technique called double exposure 3d which we placed on one of the walls of the room. Double exposure 3d is that with the help of a pair of “old” 3d glasses, which has a blue and red side, can filter out different color channels which then results in two different images, which at the same time is a whole. We made two illustrations of plastic littering where one is put on the red side and the other on the blue side. This is to represent today and how the future will look like if we continue with our unsustainable consumption and littering. The illustration is fictional and is only a representation of how the world could look in the future. The wall will also be supported by informative posters, including suggestions on what an individual can contribute with.

Recent behavioural and neural research suggests that awareness is intimately related to top-down cognitive functions such as attention. Here I present a characterization of this relationship, guided by Lavie's load theory. Load theory proposes that perception has limited capacity but proceeds automatically on all stimuli (whether relevant to the task at hand or not) until capacity is exhausted, and that the allocation of processing resources to certain stimuli (rather than to other, competing ones) is guided by executive control functions such as working memory. The theory predicts that increasing the perceptual load of a task will consume capacity, therefore reducing processing of stimuli external to that task it also predicts that increasing working memory load will impair executive control, leading to increased processing of salient ignored stimuli. Here I show that these predictions hold not only for indirect measures of perceptual processing, as has been demonstrated previously, but also for visual awareness - the subjective experience of seeing and being able to report the nature of a visual stimulus. I find that under high perceptual load, observers become less aware of the very presence of other stimuli, even when these stimuli are fully expected and serve as targets. I also show that perceptual load affects the temporal resolution of visual awareness - under high load, the ability to detect a temporal pattern (luminance flicker) is reduced, leading to a subjective percept of steady illumination. In a neuroimaging study, I show that subjective awareness of flicker is associated with activity in frontal and parietal brain regions previously associated with attention and awareness. Next, I investigate the role of executive control in visual awareness by examining the effect of working memory load on binocular rivalry, a fundamental form of visual competition. I find that high working memory load reduces dominance durations in rivalry, suggesting that working memory may serve to maintain perceptual biases during competitive interactions in visual awareness. Finally, I use Transcranial Magnetic Stimulation to establish a causal role for the previously described right parietal involvement in the control of binocular rivalry. This research therefore indicates that top- down cognitive and neural mechanisms are involved in determining whether visual stimuli will reach awareness, and in shaping the subjective nature of the experience such stimuli evoke.

Spel har förvandlats till en mainstream underhållningskälla och har utvecklats tillsammans med teknologin. Till en nivå som nyttjar en spelares alla sinnen för att fördjupa de i ett spel. Uppmärksamheten kring tillgänglighet inom spel har dock försvagats.Detta examensarbete undersöker de tillgängliga lösningarna som syftar till att hjälpa döva eller hörselskadade, främst när det gäller situationsmedvetenhet genom att ersätta ljud med en visuell representation. De i skrivande stund tillgängliga lösningarna jämförs sedan med resultaten i relaterad forskning och en undersökning som genomfördes för detta arbete. Målsättningen var att hitta vad som fungerade som en visuell representation av ljud, med undersökningssvaren som ger insikt i döva och hörselskadade individers perspektiv på lösningarna.Dessa resultat kan fungera som en referenspunkt för utvecklare som vill implementera en visuell representation av ljud eller liknande funktion i deras spel.
Video Games have turned into a mainstream source of entertainment and have evolved alongside technological improvements. To the point of being able to bring the player immersive gaming experiences that rely heavily on their senses. However, the attention to the accessibility aspects of video games has been lagging behind.This thesis explores the available solutions that aim to help Deaf or Hard of Hearing (DHH) players, primarily in terms of situational awareness by substituting audio with a visual representation. The currently available solutions are then compared with the findings in related research and a survey that was conducted for this paper. The objective was to find what worked as a visual representation of audio, with the survey responses providing insight into DHH players perspective.These findings can serve as a reference point for developers who want to implement a visual substitute for audio or a similar feature intheir game.

Musculoskeletal disorders are a chronic and debilitating issue; these injuries can result in pain and disability that affect daily life and the ability to work in certain careers. Visual artists are no exception to this reality. However, reliable research is scarce regarding this population. The purpose of this study is to examine the level of experience and awareness of visual artists regarding the subject of musculoskeletal disorders and ergonomics within their chosen career field. The methods employed for this paper involved a survey where participants answered questions about workplace ergonomics, movements, and experience of muscle pains. Further indications of research may result from this study involving the assessment, diagnosis, implementation, and intervention in the prevention of musculoskeletal disorders among visual artists.

When multiple objects are present in a visual scene, salient and behaviorally relevant objects are selectively processed at the expense of less salient or irrelevant objects. Here I used three lateralized components of the event-related potential â " the N2pc, Ptc, and SPCN â " to examine how objects compete for representation in our limited capacity visual system, and how task-relevant objects are selectively processed. Participants responded to the orientation of a color singleton target while ignoring a color singleton distractor. Competition between the objects was manipulated by presenting visual search arrays that contained only a target, only a distractor, or both objects together. In Experiment 1, observers did not know the color of the target in advance, whereas in Experiment 2 this information was provided. Experiment 3 was a control experiment to rule out low-level sensory explanations of the effects. The results suggest that the N2pc component indexes capture of attention by salient objects which is modulated both by competition between the objects and top-down knowledge. The Ptc component may index inhibition of return so that once an object is processed it is not selected again. The SPCN component may index enhancement of goal-relevant objects once task-irrelevant objects have been suppressed. Together these lateralized event-related potentials reveal the temporal dynamics of competition and selectivity in the human visual system.

Ce travail a pour objectif d'investiguer le sort réservé à  des changements de nature visuelle qui se produisent dans notre environnement et que nous ne détectons pas consciemment. J'investiguerai en particulier si de tels changements non-perçus consciemment peuvent néanmoins (1) être représentés d'une certaine manière en-dessous du seuil de la conscience, et (2) exercer une influence causale sur des tâches comportementales subséquentes. A cette fin, une première étude cherche à établir si les paradigmes classiques de détection de changement sous-évaluent les capacités réelles de la mémoire visuelle à court terme. Cette étude a effectivement montré qu'il était possible de récupérer de l'information stockée en mémoire visuelle à court terme (MVCT), suggérant donc qu'il existe plus de capacités mnésiques visuelles que ce qui est utilisé dans les tâches classiques de détection de changement. Ensuite, une seconde étude a répliqué un paradigme dit d'identification implicite de changements et qui était controversé dans la littérature en raison de biais potentiels. Après correction de ces biais, nous avons pu démontrer que ce paradigme suggère bel et bien un effet d'identification implicite de changement puisque l'identité d'un changement simple (changement d'orientation d'un rectangle parmi 8 rectangles orientés de différentes manières) peut indicer un jugement d'orientation subséquent. Finalement, dans le dernier groupe d'expériences, un nouveau paradigme dans lequel les changements se produisent très progressivement et très lentement sera décrit. En utilisant ce paradigme, j'ai pu démontrer qu'alors que les observateurs demeurent inconscients du changement, ils restent néanmoins sensibles aux changements puisqu'ils « synchronisent » leur représentation en mémoire visuelle avec le stimulus présenté à l'écran. Enfin, dans la conclusion, je m'attacherai également à  développer l'idée selon laquelle nous sommes (1) capables, au minimum, de mettre à jour notre mémoire visuelle d'un changement et probablement d'identifier, un tel changement sans conscience et (2) influençables par ce changement. En effet, à la fin de ce travail, j'arriverai à la conclusion que les représentations visuelles sont ébruitéess et incomplètes. Ceci est dû (1) à  la constitution de la rétine, qui n'est pas homogène (la quantité de photorécepteurs n'est pas identique dans la partie centrale et dans la périphérie du champ visuel), (2) aux imperfections des systèmes biologiques (des imperfections et des erreurs dans la planification des saccades et dans leurs exécutions surgissent,) et (3) aux limitations de nos capacités attentionnelles.

A rapid serial visual presentation task (RSVP) was combined with the 'inattention' paradigm (Mack & Rock, 1998) to investigate the effect of cognitive load on the detection of an unexpected stimulus. In addition, the detection of an unexpected stimulus presented in conjunction with a distractor item, rather than target, was also investigated. Seventy four students of the University of Canterbury participated in one of five experiments. Participants either performed a high cognitive load version of the RSVP task, selecting items on the basis of colour and semantic category, or a low cognitive load version selecting items on the basis of colour only. On the final frame of the fourth and critical trial, an unexpected stimulus appeared in conjunction with either a target or distractor item. The level of inattentional blindness to the unexpected stimulus was the result of interest. No effect of cognitive load or presentation partner was found. The implications of the results for the load theory of attention and cognitive control are discussed, along with the potential future uses of the developed method.

Visual conditions such as retinitis pigmentosa and Usher syndrome can gradually cause tunnel vision. Patients with these conditions usually face difficulties with navigation, avoiding obstacles, and performing visual search. Loss of mobility can affect patients' independence and quality of life. One of the rehabilitation strategies for patients with tunnel vision is the use of optical aids to enhance mobility performance. The main method used to evaluate the usefulness of optical aids is the patient’s subjective report after extended wear. In order to evaluate optical aid effectiveness in the clinic, a new test based on the visual search paradigm was designed to assess the patient's visual awareness. This was named the assessment of visual awareness (AVA) test. The main aim of this study was to develop the AVA test, establish its sensitivity, validity and repeatability, and then use it to investigate the efficacy of optical aids in this group of people. The AVA test consists of 32 peripheral targets presented at four different locations: 1st annulus (at 5° from the central fixation), 2nd annulus (10°), 3rd annulus (20°) and 4th annulus (30°)). In this study, the peripheral targets were presented singly against a spatial noise background in a presentation area of 81° H × 62° V. Participants were allowed to use head and eye movements and were asked to search for and locate each target. The detection time (DT) was recorded. A new, sensitive and easy to set up indoor mobility course was also designed and validated prior to its use in validating the AVA test. A total of 50 normally sighted participants with simulated tunnel vision (TV) (5° to 20°, in 5° steps) and 20 patients with TV (retained field 4° to 21°) were tested. The AVA test was found to be responsive to the change in field of view (FoV) and to the target locations in both groups of participants. In the simulated group, a significant relationship was found between FoV and DT at each annulus (r ranging from -0.55 to -0.77, p < 0.0001). A significant relationship was found between target location and DT within each FoV size (20°, 15°, 10° and 5°) (r ranging from 0.53 to 0.84, p < 0.0001). In the TV patients, a statistically significant relationship was found between FoV and DT at each annulus (r range from -0.40 to -0.60, p < 0.05). The target location was shown to have a significant relationship with the DT within each FoV size (r ranging from 0.50 to 0.60, p < 0.05). Finally, the AVA test was found to be significantly related to the simulated TV participants' performance on the indoor mobility course. The AVA test was used to assess the efficacy of three optical aids: the partial aperture prism (10 patients), the Tri-field prism (10 patients) and the reverse telescope (4 patients). The AVA test showed no significant improvement in DT with either of the prisms and the participants did not find these aids helpful. DT with the reverse telescope improved, but none of the participants were willing to use these on extended trial. The AVA test gave clear indications of the efficacy of each aid, a result which could affirm the importance of the AVA test. In conclusion, the AVA test was found to be sensitive, valid and repeatable. DT did not improve in either of the optical aids which were found to be unsuccessful, suggesting that the AVA could be a promising clinical test. However the aids which showed improved DT were not evaluated over the longer term, and therefore did not allow full evaluation of the AVA test.

Stimuli that cannot be perceived (i.e., that are subliminal) can still elicit neural responses in an observer, but can such stimuli influence behavior and higher-order cognition? Empirical evidence for such effects has periodically been accepted and rejected over the last six decades. Today, many psychologists seem to consider such effects well-established and recent studies have extended the power of subliminal processing to new limits. In this thesis, I examine whether this shift in zeitgeist is matched by a shift in evidential strength for the phenomenon. This thesis consists of three empirical studies involving more than 250 participants, a simulation study, and a quantitative review. The conclusion based on these efforts is that several methodological, statistical, and theoretical issues remain in studies of subliminal processing. These issues mean that claimed subliminal effects might be caused by occasional or weak percepts (given the experimenters’ own definitions of perception) and that it is still unclear what evidence there is for the cognitive processing of subliminal stimuli. New data are presented suggesting that even in conditions traditionally claimed as “subliminal”, occasional or weak percepts may in fact influence cognitive processing more strongly than do the physical stimuli, possibly leading to reversed priming effects. I also summarize and provide methodological, statistical, and theoretical recommendations that could benefit future research aspiring to provide solid evidence for subliminal cognitive processing.

At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 1: Manuscript. Paper 4: Manuscript.

In 2000, contributors to the formulation of the National Plan for Training Personnel to Serve Children with Blindness and Low Vision anticipated a severe shortage of direct service personnel as early as 2006 with an increasing negative impact on teacher numbers through the end of the decade. It is necessary to attract approximately 5,000 new teachers to the field to meet the needs of the ever-increasing population of students with visual impairments requiring specialized training.This study investigated the personality and background experiences of individuals who are attracted to work as educators with students with visual impairments. A sample of 132 teachers who had been trained at either the undergraduate or graduate level and were employed within their first five years as teachers with this specialization completed the Holland Self-Directed Search (Form CP) and a Participant Profile form to ascertain the personality types and experiences of those new to the field.The study considered three variables: (1) gender, (2) race/ethnicity, (3) teacher training level and their association with Holland personality type (RIASEC). All three variables were weak predictors of the personality type of teachers of the visually impaired as indicated by Goodman and Kruskal's tau. Results of the Holland Self-Directed Search was a stronger measure of the personality type associated with becoming a teacher of students with visual impairments. The data related to the sample revealed that 65.2% of those responding identified themselves as Social type.Teachers identified how they became aware of the field prior to making a decision to enter a teacher-training program, what their reasons were for making a decision to enter a training program to become a teacher of students with visual impairments, and which areas of their teaching experience differed from what they had expected prior to employment in the field. Limitations of the study, implications of the results for recruitment and retention of teachers of students with visual impairments, and recommendations for future research are provided.

According to the World Health Organisation, there are 180 million blind/visually-impaired people in the World. Travelling in unfamiliar scenes is one of the most troublesome tasks for the blind/visually-impaired. Limited spatial information obtained solely from sense of hearing and touching makes this task remarkably difficult. Research into the electronic travel aids (ETA) area aims to provide more spatial information for the blind and visually-impaired. There are two types of electronic travelling aids, obstacle detection ET A and orientation ETA. At present the available obstacle detection ETAs are based on sonar sensors and orientation ETAs only provide global orientation to the user. We present a new solution for a hybrid system to provide the visually-impaired with obstacle detection and local of an unfamiliar scene using computer vision sensors. Given a stereo image pair, the system creates a Spatial Information Awareness Map (SIAM). Using image gradient operators, the SIAM is extracted from the stereo disparity image. Mathematical morphology is also used as a post processing technique to clean up noise, remove isolated pixels, and improve the labelling of the spatial relationship of the scene. It is intended that the SIAM would be communicated to the user via a dynamic binary tactile map (RBTM) and work in conjunction with the traditional walking cane. The experimental results obtained from synthetic disparity and real stereo images demonstrate the validity of our approach, and shows promising results. From the RIAM, the user is provided with spatial information as horizontal lines which represent horizontal flat surfaces, and vertical lines which represent the location of objects in the scene. With SIAM, the user can locate empty space and the position of any objects in the local environment, thus allowing them to create their own cognitive map of the scene and plan their route.

Syfte: Syftet med studien var att ge en utökad förståelse för hur användandet av produktplacering kan påverka tittarnas syn på en TV- serie. Metod: Ett avsnitt av den svenska TV- serien Solsidan användes på grund av dess omfattande kritik mot användandet av produktplaceringar. Empirin samlades in genom en kombination av enkäter och fokusgrupper där 21 respondenter deltog och där de fick se ett avsnitt ur serien. Teori: Teorier om minnesprocessen, varumärkeskännedom, informationshanteringsprocessen, olika dimensioner av produktplacering samt dess för- och nackdelar har använts för att sammanlänkas med studiens resultat. Slutsats: Produktplacering medförde ingen förändrad syn på TV- serien Solsidan av olika anledningar: A)    Samtliga respondenter hade en positiv inställning till produktplacering. B)    I snitt uppmärksammades endast 29 % av placeringarna. C)    De varumärken som uppmärksammades var mycket bra integrerade och påverkade inte tittarupplevelsen negativt. D)    Produktplaceringen gjorde handlingen mer realistisk och trovärdig då respondenterna kunde relatera till liknande händelser.
Purpose: The purpose of this study was to provide an enhanced understanding about how the use of product placement can affect the opinion of a TV series.   Methodology: The Swedish TV- series Solsidan was used because of its criticism about product placement. The empirical data was collected by a combination of surveys and focus groups in which 21 respondents participated and watched one episode of the series.   Theories: Theories about the memory process, brand awareness, information processing, different dimensions of product placement and its pros and cons where used to conjoin to the results.   Conclusion: Product placement did not affect the opinion on the TV- series Solsidan for different reasons: A)     All respondents had a positive attitude towards product placement. B)    The recall of the placements was on average no higher than 29 %. C)    The brands that where noticed where well integrated and did not affect the viewing experience negatively. D)    Product placement made the scene more realistic and credible as the respondents could relate to similar situations.

The user's mobile communication device has an increasing sense of where the user is. This location information may be very fine grained or very coarse. Given some amount of location information it is possible to create location aware services. This thesis presents and evaluates a system for location aware web browsing. Indoors the user can click on a point on a map (to establish a virtual location using a previously installed user application), outdoors the location can be provided by GPS, or the location might be provided by some other location system (indoors or outdoors), then each HTTP GET request for a URL will be augmented with information about the user's location or their virtual location. Subsequently a web query is created. Then the location information encoded as longitude and latitude is appended to this web query. The web server uses this location information to generate dynamically location aware web pages. Finally a web browser shows the web pages.

Informationen om platsen kan vara lite eller omfattande. Tillgång till information om platsen gör det möjligt att skapa platsmedvetna tjänster. I den här master thesis presenterar och utvärderar jag ett system för plats medvetna web användning. Användaren klickar på en punkt på en karta (för att inrätta en virtuell lokalisering genom att använda tidigare installerat applikationer), sedan deras HTTP GET request för en URL utvidgas med information om användarens position eller deras virtuella (verkliga) lokalisering. En platsmedveten web query har skapats så att information om plats som latitude och longitude läggs till denna web query. Sedan en web server använder denna information för att generera dynamiska web sidor.
