Current research

I investigate individuals’ ability to report on their internal cognitive operations, a process known as metacognition. This involves asking participants to make simple perceptual decisions and then report their confidence in the correctness of these decisions. I use a combination of psychophysics and computational modelling to understand the core properties and computations underlying such confidence reports. One of the central questions of my PhD thesis is whether, and to what extent, these confidence computations are distinct or similar across cognitive and perceptual domains.
