Change Detection Research Interests
My first work in visual memory showed very precise discrimination for orientation changes and direction changes in single targets, persisting over ISI's up to 12 secs. More recently we found steep increases in thresholds in visual memory paradigms as a function of numbers of targets, suggesting a low-level contribution to change blindness effects. Current research uses a psychophysical approach to change detection in arrays of targets. The aim of the research is to separate perceptual, attentional and memory contributions to change detection. Planned experiments will use evoked potential methods to measure electrophysiological correlates of the detection/non-detection of change, and will examine change detection in patients with brain lesions.
Other Research Interests
Visual motion perception, stereopsis, shape-from-shading, neuropsychology, consciousness.
