Characterizing the dynamics of vestibular reflex gain modulation using balance-relevant sensory conflict
(University of Waterloo, 2023-09-21)Electrical vestibular stimulation (EVS) can be used to evoke reflexive body sways as a probe of vestibular control of balance. However, EVS introduces sensory conflict by decoupling vestibular input from actual body motion, ... -
The influence of body orientation relative to gravity on egocentric distance estimates in immersive virtual environments
(University of Waterloo, 2022-01-26)Virtual reality head mounted displays (VR-HMD) are a flexible tool that can immerse individuals into a variety of virtual environments and can account for an individuals head orientation within these environments. Additionally, ... -
Multisensory Integrative Processes and Aging
(University of Waterloo, 2022-10-04)Our sensory systems provide us with distinct impressions of our surroundings which are critical for perception, cognitive processing, and control of action. Indeed, input from multiple sensory stimuli compared to a single ... -
The Neural Processes of Perceived Simultaneity and Temporal Order in Younger and Older Adults using EEG.
(University of Waterloo, 2017-08-02)In order to make sense of the world, the central nervous system (CNS) must determine the temporal order of events and integrate cues that belong together. The process of integrating information from multiple sensory ... -
Perceived Timing of Active Head Movements at Different Speeds
(University of Waterloo, 2018-06-11)The central nervous system must determine which sensory events occur at the same time. Actively moving the head corresponds with large changes in the relationship between the observer and the environment, sensorimotor ... -
Persistent perceptual delay for head movement onset relative to sound onset with and without vision
(University of Waterloo, 2017-02-15)Knowing when the head moves is crucial information for the central nervous system in order to maintain a veridical representation of the self in the world for perception and action. Our head is constantly in motion during ... -
Psychometric correlates of multisensory integration as potential predictors of cybersickness in virtual reality
(University of Waterloo, 2019-08-16)Humans are constantly presented with rich sensory information through the environment that the central nervous system (CNS) must process to form a coherent perception of the world. While the CNS may be efficient in doing ... -
The Relationship Between Heart Rate and Self-reported Sickness in Commercially Available Virtual Reality Environments
(University of Waterloo, 2020-05-13)Virtual reality (VR), while beneficial in research, training, and entertainment has the tendency of causing cybersickness (CS). The symptoms range from mild to severe depending on the individual. There exists a gap in the ... -
Sensory Conflict: Effects on the Perceived Onset of Motion and Cybersickness in Virtual Reality
(University of Waterloo, 2023-01-03)The perception of self-motion involves the integration of multisensory information, however there are scenarios in which the sensory feedback we receive from these different sources can conflict with one another. For ... -
Visual determinants of postural control and perception during physical and visual motion
(University of Waterloo, 2023-01-30)The control of balance and posture is a critical task of daily life to limit the risk of falls and potential injury. In order to be successful in the control of balance the central nervous system utilizes sensory feedback ...
