I am Sylvain Sirois, professor within the Psychology Department of UQTR, and chairholder of the Canada Research Chair in Developmental Cognitive Neuroscience. My research interests focus on the relationship between learning and developmental mechanisms behind cognitive change. I work primarily with babies. Not as colleagues, but research participants. I have a very nice lab where we can do eye tracking and high-density EEG recordings. Pics of the lab will be up soon. With these tools, we can obtain very fine-grained behavioural and neurological data, which is helpful when trying to make sense of development in a way that is consistent with what the brain does. Ultimately, the brain IS behaviour, so keeping the brain in the loop helps us to make sense of said behaviour.
