Models of short-term memory
Probabilistic approach to cognition and memory posits humans as optimal learners who adapt to the statistical properties of the environment. Such adaptation takes place on different behaviourally relevant time scales: on the time scale of immediate inferences, as a moment-by-moment processing of sensory input, and on a longer time scale by learning from experience. In the context of human short term memory (STM) this assumes continuously updating the model of the environment in the light of newly arriving sensory information within the time scale of several seconds.
Neuroimaging of short term memory
I am particularly interested in the representation and learning of sequential information and I use fMRI to study how human memory systems participate in these processes.
