I am a postdoctoral research fellow in the School of Behaviourial Science working with Professor Philip Smith. Current work explores the dynamics of visual information processing with an aim to further develop a theory combining perceptual encoding, attention, memory, and decision making. A central feature of this theory is the use of shunting equations to model the competitive dynamics of attentional selection.
I am also interested in the representational structure of category knowledge. In particular, I am interested in the implications of apparent representational change for mathematical models of category learning. A key issue concerns the different effects of selective attention within single- and multiple-systems theories of category learning.
