Change Detection Research Interests
I am interested in the effects of task on our internal representation of the environment. Following in the Gibsonian vein of 'Perception for Action', change blindness research has revealed firstly, a failure to completely and accurately represent all parts of our visual environment, and secondly, that this representation changes as a function of many factors, including expectation and task. My work, in conjuction with Heinrich Bülthoff, has been aimed at clarifying how the representation changes as a function of the demands of the current task. In order to open up a whole range of possible tasks, we have adapted the flicker paradigm of Rensink and others to be used in a virtual environment, permitting close experimental control within a complex, dynamic and interactive environment.
