I am the director of ILLUME: The Faculty Centre for Creativity Research and my current research is focused on understanding the cognitive and affective mechanisms of creative thinking processes and how they can be influenced and enhanced. I also have a long history of work on on how people perceive, categorise and interact with the world, especially visually, and particularly on how vision can be enhanced by learning, training and experience.
We are exploring how a variety of factors such as mood, colour, the physical environment and improvisation (e.g. verbal & dance improvisation), affect the creative thinking process. This work is testing our ideas about the mapping between dual process models of cognition and models of creative thinking.
We are exploring how categories in language and thought are formed and how they relate and impact on each other in the domain of colour categorisation. This work is funded by the European Research Council and is in collaboration with Alexandra Clifford at Surrey and led by Anna Franklin at the University of Sussex. A particular focus of the work at Surrey is on the mapping between colour categories, symbolic colour associations and their influence on cognition and behaviour.
