Conference Paper
The median survival time of patients with high grade glioma, a form of brain tumour, is 1-3 years. The current best practice adopts Convolutional Neural Network (CNN) for image classification and tumour detection. This method provides a significant improvement in brain tumour segmentation of Magnetic Resonance Imaging (MRI) images in comparison to...
Chapter
Australian Army equipment is rarely designed and acquired in a manner that meets the expectations of human factors specialists; early consideration of human factors to inform human centred design. This issue is in part due to the difficulty of accessing Australian soldiers to support human centred design. One strategy to mitigate the consequences o...

Object-based attention (OBA) can - in addition to acting upon explicit object representations - act upon occluded and illusory objects. It remains unknown, however, whether or not the selection of such object representations is detectable at the same level within visual cortex. This study examined the level within visual cortex (V1-V3, LOC) at whic...
Preprint
Mechanisms of object-based attention (OBA) are commonly associated with the cerebral cortex. However, less is known about the involvement of lower visual pathways in these processes. In the current study, the classic double-rectangle cueing task (Egly et al., 1994) was implemented in a stereoscope, in order to differentiate between the involvement...
Article
The purpose of this study is to replace the manual process (selecting the landmarks on mesh and anchor points on the video) by Intensity‐based Automatic Registration method to reach registration accuracy and low processing time. The proposed system consists of an Enhanced Intensity‐based Automatic Registration (EIbAR) using Modified Zero Normalized...

Telehealth psychological services is a time‐efficient and cost‐effective therapy solution for persons in rural areas. The high congestion resulting from these infrastructure issues, which includes low‐bandwidth wireless connections and channels prone to data loss, tends to increase video delays, thereby making real‐time video transmission during te...
Article
It remains unknown whether attention selects information 'early' or 'late' in the information-processing stream. Object-based attention (OBA) is well-positioned to shed light on this long-standing debate given that some studies have reported OBA effects even when object percepts are incomplete, suggesting that perceptual object formation happens pr...

The representational basis of attentional selection can be object-based. Various studies have suggested, however, that object-based selection is less robust than spatial selection across experimental paradigms. We sought to examine the manner by which the following factors might explain this variation: Target–Object Integration (targets ‘on’ vs. pa...

Developmental prosopagnosia (DP) is commonly referred to as 'face blindness', a term that implies a perceptual basis to the condition. However, DP presents as a deficit in face recognition and is diagnosed using memory-based tasks. Here, we test face identification ability in six people with DP, who are severely impaired on face memory tasks, using...
Article
Diagnosis of developmental or congenital prosopagnosia (CP) involves self-report of everyday face recognition difficulties, which are corroborated with poor performance on behavioural tests. This approach requires accurate self-evaluation. We examine the extent to which typical adults have insight into their face recognition abilities across four s...
Article
An open question in the domain of object-based attention concerns the extent to which object-based cueing effects are affected by targets appearing as part 'of' an object (e.g., Watson & Kramer, 1999) versus 'on' an object (e.g., Egly et al., 1994). This distinction relates to whether or not the target involves a property change of the object. The...

The consequences of losing the ability to move a limb are traumatic. One approach that examines the impact of pathological limb nonuse on the brain involves temporary immobilization of a healthy limb. Here, we investigated immobilization-induced plasticity in the motor imagery (MI) circuitry during hand immobilization. We assessed these changes wit...
Article
A central question within the domain of human cognition is whether or not the ability to replace a current action with a new one (i.e., cognitive control) depends on a conscious appreciation of the environmental change that necessitates the new behavior. Specifically, it is not yet known if non-consciously perceived stimuli can trigger the modifica...

The purpose of this study was to investigate whether or not the right hemisphere can be engaged using Melodic Intonation Therapy (MIT) and excitatory repetitive transcranial magnetic stimulation (rTMS) to improve language function in people with aphasia. The two participants in this study (GOE and AMC) have chronic non-fluent aphasia. A functional...
Article
Recent studies have demonstrated that masked gaze cues can produce a cueing effect. Those studies, however, all utilized a localization task and, hence, are ambiguous with respect to whether the previously observed masked gaze-cueing effect reflects the orienting of attention or the preparation of a motor response. The aim of the present study was...

Visual attentional biases towards other-race faces have been attributed to the perceived threat value of such faces. It is possible, however, that they reflect the relative visual novelty of other-race faces. Here we demonstrate an attentional bias to other-race faces in the absence of perceived threat. White participants rated female East Asian fa...
Article
The purpose of the present study was to establish whether the validity effect produced by masked eye gaze cues should be attributed to strictly reflexive mechanisms or to volitional top-down mechanisms. While we find that masked eye gaze cues are effective in producing a validity effect in a central cueing paradigm, we also find that the efficacy o...
