Reader in Cognitive Psychology
Area of research
Memory, learning, and categorisation
My research involves experiments on human beings guided by computational models. Research areas include working memory and episodic memory (particularly for order and time); modelling of decision making; categorisation; investigation and analysis of serial correlations (1/f noise) in human cognition; and model selection issues.

My research involves the use of quantitative models to guide investigation of the processes of learning, retrieval, and performance in human cognition. One stream focussing on learning and retrieval considers memory on the order of seconds, particularly how sequences of events or stimuli are encoded and retrieved in the short term. I've recently been using connectionist and random sampling models to compare theories in this area. I am also interested in using accumulator models of choice behaviour to model relations between saccades in saccadic decision-making.
