Title: Using rapid stimulus presentation and multivariate decoding to study information processing in the human brain

Abstract: How does the brain transform perceptual inputs into conceptual representations? We have recently introduced a novel approach that combines rapid stimulus presentation, electroencephalography, and multivariate decoding analyses. This approach has several advantages. First, rapid presentation rates can be used to more closely mimic the amount of sensory information we receive in natural vision (i.e., by matching the speed at which we make saccades). Secondly, by varying the presentation speeds, we can manipulate the depth of processing that each stimulus undergoes. Finally, the paradigm can build on theories from the well-developed rsvp literature in behavioural psychophysics. In this talk, I will give an overview of the approach, and show how it can be used to answer new questions in a variety of domains, including visual processing, attention, and memory.

Biography: Dr Tijl Grootswagers joined the MARCS Institute in April this year as the second Vice-Chancellor’s Research Fellow. Dr Grootswagers is a computational cognitive neuroscience researcher who combines cutting-edge machine learning techniques, neuroimaging, and behavioural data to understand how the brain represents and processes information. He is interested in investigating how the brain perceives and represents visual objects, and how it uses these representations for decision making.
