Eyes are an ideal tool for investigating social attention, as their physiological composition with the iris and pupil highly-distinguishable against the white sclera, combined with our foveated vision, mean that gaze cues are both a means of understanding where attention is bein…

Background Individuals with Autism Spectrum Disorder (ASD) have been reported to show socio-communicative impairments which are associated with impaired face perception and atypical gaze behaviour. Attending to faces and interpreting the important socio-communicative cues presen…
Multi-User Virtual Environments (MUVEs) and Massively Multi-player On- line Games (MMOGs) are a popular, immersive genre of computer game. For some disabled users, eye-gaze offers the only input modality with the potential for sufficiently high bandwidth to support the range of …
Early breast cancer in women is best identified through high quality mammographic screening. This is achieved by well trained health professionals and appropriate imaging. Traditionally this has used X-ray film but is rapidly changing to utilise digital imaging with the resultan…
During my PhD research I investigated the possible roles of fixational eye movements (FeyeM) in visual perception. It is commonly accepted among researchers in this area, that FeyeM are divided into three types of eye movements, namely; Drift, Tremor and Microsaccades. The main …
This thesis explores the effects of discourse context, specifically whether a referent is discourse-given or discourse-new, on the online processing of the dative alternation and the active/passive alternation. Previous research provides support that the discourse status of a re…
People of different cultures tend to have different cognitive processing styles. Philosophers throughout the years have believed that culture fundamentally shapes human social practices and intellectual processes (Nisbett, 2004). Cognitive styles have been found to be significan…
Medical images constitute a special class of images that are captured to allow diagnosis of disease, and their "correct" interpretation is vitally important. Because they are not "natural" images, radiologists must be trained to visually interpret them. This training process inc…
Research on interactions with multimedia instruction can reveal a great deal about the impact of visualization and its affect on learning. Eye-tracking is one of the methods used to examine visual processing. Eye tracking provides a unique opportunity to test hypotheses that rel…
Recent studies in medical radiology have used eye tracking technology to identify optimal search patterns in volumetric radiologic interpretation. To date, no studies focused on eye tracking during dynamic cone beam computed tomography (CBCT) interpretation in endodontics have b…
Eye tracking is a growing measure of concussion deficits that provides insight into complications caused by traumatic impacts. Clinical and technology-based eye tracking measures may provide insight into specific complications resulting from previous concussion. The aim of this …
Cognitive efficiency—characterized via robust behavioral and physiological response dynamics, may provide clinically meaningful information with respect to dynamic concussion injury response and return to play considerations. Moreover, a feasible and ecologically valid method to…
Successfully navigating the world on a moment-to-moment basis requires the interaction of multiple cognitive processes. Therefore, studies that examine when and how these fundamental processes interact can provide important insights into how we behave. Many studies indicate that…
