I am interested in mathematical and computer simulation models of memory, learning, retrieval, attention, limited capacity, automatism, and perception, and empirical research to test and develop these models.

In recent years I have paid particular interest to memory retrieval, and have contrasted traditional models with parallel, distributed, composite models, and a new model based on Bayesian optimal retrieval. The new model is aimed to explain storage and retrieval not only of recent events, but of general knowledge and the relation between the two. The empirical research explores different ways in which memory is accessed, such as recall, recognition, or implicit tests.

Another major line of work involves limited capacity in human information processing (both in memory and perception) and ways in which the development of automatic processes allow such attentional limitations to be overcome. This work is carried out largely in the domains of visual and memory search tasks.

Other current research involves the learning of word and letter units, perception and recognition, and the modeling of processes underlying response times in attention and memory tasks.
