The ability to navigate without getting lost is an important aspect of quality of life. In 5 studies, we evaluated how spatial learning is affected by the increased demands of keeping oneself safe while walking with degraded vision (mobility monitoring). We proposed that safe low vision mobility requires attentional resources, providing competition for those needed to learn a new environment. I...

PURPOSE To report two cases of solitary unilateral vitreous cyst. METHODS A complete ocular examination, fundus photography, B-scan ultrasound and spectral-domain optical coherence tomography were performed in both patients. RESULTS The first patient (a 39-year-old man) presented with transient blurred vision in the right eye. The second patient (a 78-year-old man) reported transient blurre...

The apparent motion reveals what in an image that human vision detects first. Chen's assumption that early stage vision can percept global topology is proved incorrect in theory and experiments. Based upon psychological studies on human vision, a new theory, the blurred matching, was introduced into visual computation which well fits the results of all experiments about apparent motion, Chen's ...

In 2 experiments, the authors examined how characteristics of a simulated traffic environment and in-vehicle tasks impact driver performance and visual scanning and the extent to which a computational model of visual attention (SEEV model) could predict scanning behavior. In Experiment 1, the authors manipulated task-relevant information bandwidth and task priority. In Experiment 2, the authors...

Globalisation of industry, technological advances, and the blurring of geographic and economic borders have, until recently, all contributed to an increase in mergers and acquisitions activity. Yet do these developments actually lead to any benefits? Focusing on the banking sector, Alan Horncastle, Oxera Principal, and Professor Subal Kumbhakar, Associate, consider how econometric techniques ca...
