▼ Vection is a phenomenon in which a person feels as if he or she is moving, but there is no actual movement.
Vection can be broadly categorized into linear
vection (up-down or back-and-forth), circular
vection (around your standing location or around your line of sight), or curvilinear
vection. In this thesis, three virtual stimulus environments were simulated based on the Oculus Rift DK1, a commodity-level wide-field-of-view head-mounted display. We also had access to an optokinetic drum, a circular chamber with rotating stripes that can induce
vection in the real world. In a comprehensive study, we compared these forms of stimuli to see how well they induce
vection. We did so by measuring
vection onset latency, and subjective ratings of how intensive and convincing the
vection was. Thus, five stimuli were compared: linear horizontal and verticle virtual stimuli, circular virtual stimulu, the optokinetic drum with a full, naturalistic field of view, and the optokinetic drum with a field of view matched to our head-mounted display. Linear
vection was induced faster than any other type, while circular
vection in the real world occurs more rapidly than a virtual one. These results may have application to the design of virtual environment locomotion interfaces.

▼ This thesis is concerned with the sense of orientation. Vestibular, podokinetic and visualsystems can all contribute to our sense of orientation in space. However, each provides the brain with different qualitative information in different reference frames. The aim of this work was to determine how these different sensory systems are fused to create a coherent internal representation of self-motion relative to the external environment and how this is used to guide locomotion.Vestibular stimulation with galvanic currents (GVS), podokinetic stimulation on a rotatingplatform, visual stimulation in a rotating visual scene all can evoke signals of rotation about the
subjects vertical axis. Healthy adult subjects were presented with a rotating stimulus of one or more afferent channels and perceptual, postural or locomotor responses during and following stimulation were recorded.GVS allowed systematic study of vestibular signals in isolation. Chapter 2 demonstrated these signals are interpreted within the CNS as head acceleration and revealed the peripheral and central vestibular adaption processes.Chapter 3 investigated the podokinetic after-rotation trajectory following a range of conditioning parameters and developed a model of podokinetic adaption incorporating vestibular feedback.Chapter 4 measured blinded locomotor responses during GVS which showed evidence of a podokinetic adaptation which summated with the vestibular response.Chapter 5 showed that a rotating vestibular signal in the presence of a stationary visual signal is rapidly recalibrated to the visual signal. Blinded after-rotation in the direction of the prior vestibular conditioning stimulus suggests the signal also undergoes adaptation according to vestibular processes.Rotating optic flow in Chapter 6 evoked illusions of self-motion but the dominance of vision on the sense of orientation diminished as the speed of optic flow increased. After-rotation trajectories revealed that the perception of self-motion which can be influenced by optic flow or the belief framework is the reference to which currently active sensory channels are calibrated.Chapter 7 investigates the locomotor responses following multisensory stimulation in conflicting and corresponding directions and demonstrated interactive influences of multiple inputs on the perception of self-motion.A conceptual model which incorporates the recalibration, adaptation and reweighting processes uncovered in the experimental chapters is presented in Chapter 8.

▼ Purpose: Our lab has previously shown that patients with early glaucoma have dysfunctional
vection responses. We attempted to explain this finding using a combined index of structure and function (CSFI), originally proposed by Medeiros et al. (OVS 2012;130(9):1107-1116)
Methods: Roll and circular
vection were evoked using a back projected screen (Experiment 1) and the Oculus RiftTM system (Experiment 2), respectively. The CSFI, was obtained using clinical data from visual field tests and optical coherence tomography.
Results: In Experiment 1, the log of
vection latency was significantly longer for patients with glaucoma (t(21) = 2.39, p < .05). In Experiment 2,
vection latency was significantly longer for the glaucoma group for both stimulus speeds (F(1,22) = 6.38, p = .019). However, the CSFI was not related to
vection latency, duration, or rating (smallest p = .06).
Conclusion: In two different studies we replicated the finding that
vection responses are longer in patients with glaucoma; however, the CSFI is not related to
vection responses.

▼ Several lines of research on converge for the conclusion that high and low hostile men differ with respect to autonomic regulation of stress. The functional cerebral systems approach has provided a theoretical framework to account for this finding across the individual sensory, motor, and premotor modalities. The current experiment extends and elaborates upon a functional cerebral systems based model that posits a role for the right frontal region in regulation of sympathetic tone after stress. The experiment builds upon prior work illustrating the utility of this model to stress by positing mild dizziness as a potential frontal lobe stressor demonstrating hostility group differences in sympathetic arousal. Dizziness was induced by brief clockwise angular rotation about the vertical neuroaxis. Consistent with vestibular research indicating clockwise rotation impacts the right hemisphere (relative to counterclockwise rotation), it was expected that hostile individuals would exhibit higher skin conductance levels after rotation compared with low hostile individuals. The experiment also included a dichotic listening task both before and after rotation to examine the effects of rotary stress on dichotic phoneme identification. The experiment was conducted in three blocks: A dichotic listening task comprised the first block, followed by application of rotary stress as the second block, and a follow-up dichotic listening task post- rotary stress. It was predicted that rotation would induce an auditory perceptual shift towards the left ear. Results confirmed expected group differences in sympathetic response to rotary stress. High hostiles had greater overall skin conductance immediately following rotation. High hostiles failed to habituate skin conductance levels to mild rotation 7 minutes post-rotary stress. Lateralized effects of skin conductance remain unconfirmed at this time. No group differences were found for either block of the dichotic listening task. Overall, results are interpreted to support a model of frontal region capacity limitation for regulation of stress, including vestibular dysfunction.

▼ The study of visual illusions of self-motion, or vection, has a long history of research dating back to its first descriptions by Helmholtz (1867). Early vection studies tended to induce vection in physically stationary observers or passively moved observers (externally generated perceptions of self-motion). It has not been until recently that studies have examined this experience in actively moving observers (self-generated perceptions of self-motion). With continuing advances in technology, it has become increasingly more important to understand the perception of self-motion in active, moving observers where there is some interaction between the observer and the virtual visual environment. This thesis consists of four experimental chapters. These chapters examined the effect of consistent and inconsistent multisensory self-motion stimulation (compared to stationary vision-only self-motion situations) on the strength of vection in depth during active seated head movements (Empirical Chapters 1-3) and during treadmill walking (Empirical Chapter 4). In addition, this thesis examined the robustness of the viewpoint jitter and oscillation advantage for vection (compared to non-jittering constant velocity optic flow) under different self-motion situations and contexts. Overall, both vection in depth and the viewpoint jitter/oscillation advantage were remarkably tolerant to inconsistent multisensory self-motion situations; however, consistent visualvestibular information was shown to increase vection in depth compared to vision-only conditions in some seated self-motion situations. Together, the findings of this thesis suggest that multisensory interactions during vection in depth are more complicated than originally thought and depend on a number of factors - including the physical/simulated axis of self-motion, the type and level of multisensory conflict and the type and number of senses involved. Specifically, this thesis showed that: (i) consistent horizontal (but not depth) visual-vestibular information during active seated head movements increased vection in depth compared to vision-only conditions; and (ii) biomechanical information about self-motion during treadmill walking globally reduced vection in depth compared to vision-only conditions. However, despite overall reductions during treadmill walking, there was always a viewpoint jitter and oscillation advantage for vection.

▼ Gravity is the most pervasive force that we encounter. For instance, we observe a variety of objects being accelerated toward the Earth by gravity, but we also experience these forces when we are simply stationaryas gravity is a constant accelerationor when we are ourselves in motion, such as when we are locomoting on foot, driving a vehicle, jumping or skiing. It follows that our ability to successfully navigate our environment must somehow take into account the effects of gravity on our body's motion-detecting sensesa dynamic relationship which changes with self-motion and self-orientation. The goal of this dissertation was to investigate how body orientation relative to gravity influences visual-vestibular interactions in visually-induced perception of self-motion (i.e.,
vection). Specifically, I examined this relationship by placing observers in varied postures and presenting visual displays simulating forward/backward self-motion with vertical/horizontal viewpoint oscillation, that mimics components produced by head-movements in real self-motion. I found that tilting observers reduced
vection and the two viewpoint oscillations similarly enhanced
vection, suggesting that current postural and oscillation-based
vection findings are best explained by ecology. I also examined the influence of scene structure and alignment of the body and visual motion relative to gravity on
vection. Observers in different postures viewed simulated translational self-motion displays consisting of either a single rigid structure or dots. The experimental data showed that
vection depended on both posture and the perceived interpretation of the visual scene, indicating that self-motion perception is modulated by high-order cognitive processes. I also found that observers reported illusory tilt of the stimulus when they were not upright. I investigated these observer reports of a posture-dependent perceived stimulus tilt by presenting upright and tilted observers with static and motion stimuli that were tilted from the graviational vertical. Postural-dependent tilt effects were found for both these stimuli and were greater for motion experienced as self-motion than external motion. Taken together, the results of this dissertation demonstrate that our perception of self-motion is influenced by gravity, and by prior experiences and internal mental representations of our visual world.

▼ Lorsqu’ils explorent leur environnement, les humains comme les autres animaux ont la capacité d’utiliser de nombreuses sources d’information afin d’estimer la distance qu’ils parcourent. Le flux optique est un indice important dans la perception de la distance parcourue. De plus, il a été montré que l’ajout d’un point de vue oscillant à une simulation visuelle de mouvement propre vers l’avant modulait cette perception. A travers ce travail, nous nous sommes intéressés à tester si la perception de la distance parcourue était également affectée par un point de vue oscillant, mimant de manière plus ou moins fidèle les mouvements de la tête lors de la marche. Dans six premières expériences, il était demandé aux participants stationnaires, confrontés à un flux optique simulant leur propre mouvement vers l’avant, d’indiquer quand ils pensaient avoir atteint la position d’une cible distante initialement perçue. Une expérience subséquentes s'est intéressée à déterminer si l’absence de ces oscillations jouait un rôle important dans l’estimation de la distance parcourue lorsqu’ils marchaient sur un tapis roulant. Enfin, dans une dernière expérience nous avons développé une mesure dynamique de la distance parcourue à travers l’utilisation d’une tâche demandant aux participants de pointer continuellement la position d’une cible distante initialement perçue. Dans l’ensemble, nos résultats montrent qu’un point de vue oscillant joue un rôle important dans la perception visuelle du mouvement propre et que de nombreux paramètres semblent être impliqués dans ce processus, incluant les informations visuelles et proprioceptives mais également l’aspect écologique de la marche naturelle.
When exploring their environment, humans and other animals have the ability to use many sources of information to estimate the distance they travel. Several studies have shown that optic flow is a significant cue to perceive distance travelled. Furthermore, it was found that adding various viewpoint oscillations to a purely translational optic flow, simulating forward self-motion, modulated this perception. In a series of experiments, we tested whether the perception of distance travelled was also affected by viewpoint oscillation, similar to head motion during natural walking. A first series of experiments, participants were exposed to an immersive optic flow simulating forward self-motion and they were asked to indicate when they thought they had reached the remembered position of a previously seen target. Two further experiments aimed to test whether the idiosyncrasy of viewpoint oscillations affects the perception of distance travelled in stationary observers and whether the absence of their own viewpoint oscillation played an important role in subjects’ estimates, while they were walking on a treadmill. And finally, in a last experiment we tried to develop a dynamic measure of distance travelled to a previously seen target, with a continuous pointing task method. Overall, our results show that viewpoint oscillations play an important role in…

▼ Spatial disorientation is a major contributor to aircraft mishaps. One potential contributing factor is
vection, an illusion of self-motion. Although
vection is commonly thought of as a visual illusion, it can also be produced through audition. The purpose of the current experiment was to explore interactions between conflicting visual and auditory
vection cues, specifically with regard to the speed and direction of rotation. The ultimate goal was to explore the extent to which aural
vection could diminish or enhance the perception of visual
vection. The study used a 3 × 2 within-groups factorial design. Participants were exposed to three levels of aural rotation velocity (slower, matched, and faster, relative to visual rotation speed) and two levels of aural rotational congruence (congruent or incongruent rotation) including two control conditions (visual and aural-only). Dependent measures included
vection onset time,
vection direction judgements, subjective
vection strength ratings,
vection speed ratings, and horizontal nystagmus frequency. Subjective responses to motion were assessed pre and post treatment, and oculomotor responses were assessed before, during, and following exposure to circular
vection. The results revealed a significant effect of stimulus condition on
vection strength. Specifically, directionally-congruent aural-visual
vection resulted in significantly stronger
vection than visual and aural
vection alone. Perceptions of directionally-congruent aural-visual
vection were slightly stronger
vection than directionally-incongruent aural-visual
vection, but not significantly so. No significant effects of aural rotation velocity on
vection strength were observed. The results suggest directionally-incongruent aural
vection could be used as a countermeasure for visual
vection and directionally-congruent aural
vection could be used to improve
vection in virtual environments, provided further research is done.

▼ This thesis investigates different interpretations of visual background motion with regards to the visual awareness of objects. Motion-induced blindness (MIB) is a phenomenon in which stimuli superimposed on a moving background spontaneously disappear. Does MIB depend on how background motion is interpreted? York Universitys Tumbling Room is a full-size room that rotates around an observer. Within this room, the disappearance of static targets (MIB) was measured under two interpretations of background motion: 1) perceived self-motion 2) external motion. The speed of the room, eccentricity of targets, and physical self-motion were also manipulated. Visual background motion that induced the sensation of self-motion, regardless of whether it was illusory or physical rotation unlike when background motion was perceived as external did not generate MIB. I conclude that MIB depends on the way the brain processes visual motion information.

▼ La Flavescence dorée est une maladie à phytoplasme incurable qui affecte la vigne. Cette pathologie est uniquement transmise de plante à plante par la cicadelle vectrice Scaphoideus titanus. Malgré l'importance de cette maladie, peu d'études ont été menées sur le vecteur. Ce travail de thèse vise à apporter des connaissances sur la biologie et l'écologie de S. titanus mais aussi de manière plus générale sur l'écologie des insectes phytophages. Trois grands thèmes ont été abordés dans ce mémoire : i) les relations entre l'insecte et son environnement à travers l'influence des températures hivernales sur les œufs en diapause, ii) les relations de l'insecte avec sa plante hôte en examinant l'attractivité de cette dernière et le comportement alimentaire du vecteur, iii) les interactions entre congénères par l'étude du comportement d'agrégation des larves. Les résultats obtenus indiquent que 1) des températures froides ne sont pas indispensables à la levée de diapause mais affectent la protandrie en régulant le sex-ratio opérationnel, 2) l'attractivité de la plante hôte est en grande partie liée à sa couleur et il existe des différences de comportement en fonction du stade de développement, 3) les mâles et les femelles n'ont pas le même comportement alimentaire, ce qui pourrait expliquer leur différentes capacités de vection, 4) l'agrégation des larves ne semble pas due à un recrutement actif de leur part et pourrait contribuer à un transfert horizontal de phytoplasme d'insecte à insecte via la plante. A terme, ces connaissances pourront contribuer à l'élaboration de pistes alternatives à la lutte chimique actuelle contre cette cicadelle dans le cadre d'une réduction des intrants.
The Flavescence dorée is an incurable phytoplasma disease of grapevine. This pathology is exclusively transmitted from plant to plant by the leafhopper vector Scaphoideus titanus. Despite the importance of this disease, few studies have been conducted on the vector. This thesis aims to provide knowledge on the biology and ecology of S. titanus but also more broadly on the ecology of phytophagous insects. Three major themes were addressed in this thesis: i) the relationships between the insect and its environment through the influence of winter temperatures on diapausing eggs, ii) the relationships of the insect with its host plant by examining the attractiveness of the plant and the feeding behaviour of the vector, iii) interactions between congeners in the study of the aggregative behaviour of larvae. Our results indicate that 1) cold temperatures are not essential to break the diapause but contribute to protandry through operational sex ratio regulation, 2) the attractiveness of the host plant is largely due to its colour and different instars exhibit differences in behavioural choices, 3) males and females have different feeding behaviour which may explain their different efficiencies at vection, 4) the aggregation of larvae did not seem to result from active recruitment and could contribute to horizontal insect to insect transfer of…

▼ This study examined the relationship between the magnitude of vection (visually induced perception of self-motion) and the forward body tilt induced by optokinetic stimulation (OKS). Twelve healthy adult subjects participated in this study. A moving random dot pattern as an OKS was projected on a large hemispherica1 dome screen placed in front of the subject. The pattern was moved downward on the screen. Each subject stood on a force-measuring platform in Romberg's position and gazed at a red fixation point in the center of the screen. OKS velocity in a range of 10 to 100 deg/sec was presented in random order. The magnitude of pitch vection caused by OKS was measured by the ten-point assessment method. The body sway values registered by the force-measuring platform were stored on a data recorder. After the antero-posterior component of body sway was converted by 12 bit A/D converter, a maximum point and average level of forward displacement of center of gravity caused by OKS was calculated by computer. Power spectrum analysis was applied for anterio-posterior body sway by the FFT method. From these analyses it was concluded that there was a close relationship between the magnitude of vection and the forward displacement of center of gravity caused by OKS. This suggests that the vection induced by moving patterns strongly modifies readjustment of the upright standing posture. 直立姿勢を維持した被験者に対して、視野の広い部分に動くパターン(視運動刺激、optokinetic stimulation)を呈示すると、パターンの移動方向へ自己の身体の運動感覚(vection) を知覚すると同時に、パターンの移動方向への身体傾斜が誘発される。本研究においては、直径150cmの半球状スクリーンの内側を、上方から下方へと移動するランダムドットパターンを被験者に呈示する事により、知覚されるvectionの大きさと、誘発される直立姿勢の傾斜の大きさとの関係について検討することを目的とした。12名の健康な被験者が実験に参加した。被験者らは、暗室内においてRomberg姿勢でforce platform上に直立し、前方に置かれた半球スクリ-ン中央の、赤色レーザースポットによる固視点を注視した。視運動刺激速度は、10deg/secから100deg/secまでの範囲について、10deg/sec毎の角速度を、無作為な順序で60秒間呈示した。Vectionの大きさは10点表示法を用いて定量化し、口述により測定終了直後に報告させた。視運動刺激中の直立姿勢変化は、前後方向の重心動揺軌跡をA/D変換し、視連動刺激中における重心の前方移動量を計測し換討した。また、FFT法により重心動揺軌跡の周波数解析を行った。視運動刺激中においては、直立姿勢の前傾と、一定刺激速度時における前傾維持姿勢が観察された(直立姿勢の再調節)。視運動刺激によって誘発されたvectionの大きさと重心の最大前方移動量との間には密接な関係が認められた。これは、視連動刺激によって誘発される直立姿勢の再調節の大きさは、vectionの知覚の大きさに依存することを示唆する。

▼ It is well established that exposure to virtual motion environments (VME) can elicit postural instability (PI) in addition to motion sickness (MS). While research has found sex differences in motion sickness, the results of experimental studies are equivocal regarding these differences, and previous studies utilizing VME have failed to address the factor of sex differences in terms of hormonal fluctuations, which may also be instrumental in behavioral responses to VME, such as PI. The intent of this investigation was to determine whether exposure to VME, during various phases of the menstrual cycle (premenstrual, permenstrual, ovulation) would reveal sex differences in MS and PI during some phases, but not others. The first experiment involved men and women completing Daily Living Logs for a period of 40 days to provide a baseline for any sex differences (and for women, menstrual phase differences) in motion related activity and symptomatology. The second experiment involved 24 participants (6 men) viewing a rotating Archimedes spiral for a period of twenty minutes. Exposures were timed to place each woman in three phases of her menstrual cycle; men were exposed by yoking their exposure time to a female counterpart. Multiple measures of PI and MS were recorded before, after and during exposure. Results of the first experiment found no significant effects of sex or phase upon symptomatology, revealing no support for the theory of a reporting bias as influencing sex differences in MS or PI elicited in the laboratory. The second experiment found no significant effect of sex of phase upon any of the PI measures, but found significant interaction effects of sequence and phase, as well as sequence and sex, upon reported magnitude ratings of illusory self-motion perception. There were also significant effects of sex found upon measures of MS, with women reporting more discomfort to exposure to motion stimulation, as compared to men. There were no significant effects of phase upon any of the MS measures. While these findings show no support for a reporting bias influencing the sex differences found experimentally induced MS, it yields no evidence to support a hormonal influence on these differences.

▼ Low immersion and sickness experienced in virtual reality (VR) are two important barriers that inhibit the widespread adoption of VR technology. Both are thought to relate to visual-vestibular mismatch. Recoupling multisensory cues can generate more convincing illusory self-motion (vection) and reduce sickness, but current methods rely on expensive or invasive techniques to simulate expected cues. According to a Bayesian framework of sensory integration, adding sensory noise may also reduce mismatch by changing sensory weights. This thesis explores this idea and proposes that ‘noisy’ vestibular stimulation presents an attractive solution to the above problems.
I investigated the potential for improving VR experiences using two techniques that generate noise in the vestibular system. Rather than recoupling the senses, I aimed to encourage discounting of vestibular cues that are inconsistent with vision. In Chapter 2 I assessed the potential for improving immersion by measuring the effect of noisy vestibular stimulation (either bone-conducted vibration, BCV; or galvanic vestibular stimulation, GVS) on vection onset latency. I found a large reduction in vection latency when transient BCV or GVS were used at visual motion onset. The evidence suggests that a more compelling sensation of self-motion is achieved when sensory mismatch is reduced.
In a second study I examined the extent to which sickness is reduced when BCV is applied during path navigation in a high-end VR display (Chapter 3). Results revealed lower sickness when transient noisy stimulation was applied. In a replication of this experiment I found that BCV reduced sickness to a similar extent when observers used a commercial head-mounted display.
The results of Chapter 2 and 3 offer evidence that BCV reduces multisensory mismatch by down-weighting vestibular information according to Bayesian cue combination models. Given this context I also expected BCV to reduce self-motion sensitivity in a real-world movement discrimination task (Chapter 4). The results of a third study did not support my predictions, suggesting that the effects of noisy stimulation on self-motion may be more complex than previously considered.
Together the findings give rise to a variety of opportunities for further testing of the technique, which are discussed in Chapter 5.

▼ Vection is an illusion of visually-induced self-motion in a stationary observer. I used different types of
vection stimuli in a functional magnetic resonance imaging (fMRI) study to determine the interaction between cortical visual regions and cortical vestibular regions during
vection. My findings suggest that the cingulate sulcus visual area is heavily involved in self-motion processing. The parieto-insular vestibular cortex, showed a significant change in blood oxygenation level dependent signal activity during
vection but to a lesser extent than CSv. Behavioural data correlated with the neuroimaging data (in CSv and PIVC) as both show a significant difference when comparing the radial oscillating condition to the radial smooth condition in CSv and PIVC - suggesting a neural correlate of the jitter effect. My results suggest that the brain region of primary importance in the self-motion debate is CSv - a region that has received little attention in the
vection literature to date.
