Investigating Spatial Working Memory and Saccadic Remapping Processes in Healthy Young and Elderly Participants
(University of Waterloo, 2009-08-28)Additional cognitive deficits, including impairments in spatial working memory and/or saccadic remapping processes, have recently been implicated in unilateral neglect – a neurological condition classically characterized ... -
The Investigation of Long-term Cognitive Changes after Mild Traumatic Brain Injury using Novel and Sensitive Measures
(University of Waterloo, 2012-08-24)Memory and concentration problems are frequently reported long after experiencing a mild traumatic brain injury (mild TBI), though conflict with null findings of deficits on standard neuropsychological tests. Experimental ... -
Isovist Analysis as a Tool for Capturing Responses Towards the Built Environment
(University of Waterloo, 2013-05-02)Experience of the built-environment is said to be dependent on visual perception and the physical properties of space. Scene and environmental preference research suggests that particular visual features greatly influence ... -
June Must be Right and 9 is on Top: An Investigation of Time-space and Number-form Synaesthesia
(University of Waterloo, 2011-01-04)Synaesthesia is a fascinating condition whereby individuals report extraordinary experiences when presented with ordinary stimuli. In this thesis, we examine an individual (L) who experiences time units (i.e., months and ... -
Memory across trials in visual search
(University of Waterloo, 2009-09-03)In two experiments we evaluated whether memory for item locations across trials can improve visual search performance. Measuring both response times and eye movements we examined how visual search performance is influenced ... -
Modulation of Gaze-oriented Attention with Facial Expressions: ERP Correlates and Influence of Autistic Traits
(University of Waterloo, 2013-09-27)The direction in which another is looking at triggers a spontaneous orienting of attention towards gaze direction in the viewer. However, whether the facial expression displayed by the gazing individual modulates this ... -
'Oops! I can't believe I did that!' Inducing Errors in a Routine Action Sequence
(University of Waterloo, 2010-10-21)‘What was I thinking ?!?’ – No matter age, intelligence or social status, we all experience moments like these. Perhaps it is walking into a room and forgetting what you went there to do or maybe failing to add sugar to ... -
Perceptuomotor incoordination during manually-assisted search
(University of Waterloo, 2012-07-03)The thesis introduces a novel search paradigm, and explores a previously unreported behavioural error detectable in this paradigm. In particular, the ‘Unpacking Task’ is introduced – a search task in which participants use ... -
Physiological and Affective Responses to Immersion in Virtual Reality: Effects of Nature and Urban Settings
(University of Waterloo, 2010-08-16)With the rapid advancements in technology, researchers are seeking new ways to incorporate modern high-tech solutions such as virtual reality into treatment paradigms for stress. The current experiment explores the beneficial ... -
RELPH: A Computational Model for Human Decision Making
(University of Waterloo, 2013-09-19)The updating process, which consists of building mental models and adapting them to the changes occurring in the environment, is impaired in neglect patients. A simple rock-paper-scissors experiment was conducted in our ... -
The science of navigation: An analysis of behavioural differences between good and poor wayfinders
(University of Waterloo, 2013-04-15)Everyday experience suggests that certain people can find their way to a destination easily, while others have considerable difficulty. This dissertation focused on gaining a greater understanding of navigational strategies ... -
Slow and Steady Improves Accuracy in Attention Tasks: Implications for Evaluating Attention Training
(University of Waterloo, 2012-08-29)There have been increased efforts to develop methods for improving attention across a range of tasks including those assessing sustained attention. Using a variety of techniques, researchers have reported modest reductions ... -
The Source of the Positivity Bias in Older Adults' Emotional Memory
(University of Waterloo, 2007-05-18)According to socioemotional selectivity theory (SST), old age is associated with a greater emphasis on self-regulation of emotional states, a focus that fosters a bias in processing positively valenced material in older ... -
Spatial deficits in visuomotor control following right parietal injury
(University of Waterloo, 2007-05-22)Superior parietal cortex has been implicated in visuomotor guidance and is proposed to be specialised for action in the lower visual field and peripersonal space. Two patients, one with a right superior parietal lesion ... -
Statistical learning in brain damaged patients: A multimodal impairment
(University of Waterloo, 2014-03-19)Spatial neglect has mainly been described through its spatial deficits (such as attentional bias, disengagement deficit or exploratory motor behavior), but numerous other studies have reported non-spatial impairments in ... -
Subtle Effects of Sleepiness on Electrocortical Indices of Attentional Resources and Performance Monitoring
(University of Waterloo, 2007-02-19)In this dissertation, the effect of mild sleep deprivation on attentional allocation and performance monitoring was investigated using a variety of event-related potential (ERP) paradigms with ecologically realistic periods ... -
Towards a Theory of Visual Concealment
(University of Waterloo, 2010-08-26)The goal of this dissertation is to take initial steps towards understanding concealment behaviour and ultimately developing a theory of visual concealment. Since there are relatively few studies of concealment in the ... -
Understanding the influence of anxiety on gait in Parkinson's disease
(University of Waterloo, 2015-07-15)Anxiety is a prevalent non-motor symptom of Parkinson’s disease (PD) and has been linked to motor impairments in PD, yet there is a huge gap in the understanding of whether anxiety affects movement, namely gait, in those ...
