My research seeks to understand the brain mechanisms of visual perception. Click here for a list of my published papers.
I am currently working on aspects of motion perception with Dr Ignacio Serrano Pedraza of the Complutense University in Madrid and Dr Louise Delicato of the University of Sunderland. We are interested in the relationship between the spatial structure of briefly-presented moving patterns and human ability to discriminate their direction of motion. Our work builds on a two accepted facts about human visual processing:-
- Information about direction and speed of motion of local features in the visual image is extracted at a very early stage of visual processing.
- Information about motion is extracted separately for fine-scale features – such as the features in a face – and coarse-scale features – such as the head, of which the face is a part. Different mechanisms process the motion of fine features and coarse features.
