Biography

Research Interests

My research falls into two related strands, one examining the relationship between visual attention and visual consciousness and the other the perception of the material properties of objects. In both areas I have tested the deficits suffered by neuropsychological patients in order to arrive at hypotheses about the manner in which psychological functions are broken down into sub-processes in the brain. I then go on to test these hypotheses using neuroimaging and psychophysical methods in normal people.

In 1999 I discovered that that prompting neurological patients to attend to areas in which they reported that they were blind as a consequence of their brain damage could, nevertheless, improve their ability to respond accurately to stimuli of which they were unaware. This dissociation between visual attention and awareness had major implications for theories about the basis of consciousness in the brain, for philosophers of mind and for the development of methods for rehabilitating patients with this, very common, form of brain damage. I have demonstrated the same dissociation in normal people for a variety of forms of attention. I have also applied these findings to development of methods of training stroke patients rendered partially blind to recover the ability to read. 

I also use psychophysical methods to understand the neural basis of colour perception by testing the abilities of patients with brain damage affecting colour vision. The processing of properties of materials such as texture, glossiness and translucence in the brain can be studied in a similar fashion. In a pair of papers combining psychophysics, work with neurological patients and neuroimaging, my colleagues and I were the first group to demonstrate specific areas in the brain for the processing of shape colour and texture. I have just published work extending this approach to the perception of glossiness and am currently developing computer programs allowing similar studies to be undertaken on the perception of translucence. These properties have a tremendous influence on our perception of the world. Inappropriate glossiness or translucence make people look like waxworks, milk look like paint and fruit look rotten. Understanding how we perceive these properties has implications well beyond basic psychological science in computer-graphics and consumer-products industries.
