My main interest is understanding how our prior knowledge influences how we perceive and attend to the world. How would looking at a stop sign influence the attention of someone walking into a cafe? Would my attention be drawn towards ordering a hot drink if I suddenly feel the chill of the AC?
I am also interested in understanding how semantic associations are acquired through experience and in modeling how the attentional system dynamically prioritizes information.
To understand these questions, I utilize both behavioral and neuroimaging methods (functional MRI). I also rely on online data collection (via Amazon MTurk and Testable) as well.
