Background

I investigate the neural correlates and behavioural mechanisms that underpin how people apply cognitive and physical effort to obtain rewards and avoid unpleasant situations. I am also interested in computationally modelling biases and affective states that contribute to evaluations of effort cost, with the aim of better understanding the roles that differing cognitive mechanisms play in people’s perception of effort. Beyond my research, I also help organize and co-teach an annual fMRI brain camp for undergraduates, graduate students, and faculty from UBC and SFU, and have helped organize the annual PsychFest conference for UBC Psychology graduate students.

Research Interests

Sounds in Context
What makes a sound unpleasant? When we’re bothered by something we hear, are we averse to the sound’s acoustic content (e.g. screeching noises or a loud volume) – or does the sound bring to mind an unpleasant past experience? And what role does a sound’s context play in our perception of it being aversive? These are some of the questions that I am currently exploring in the BAR Lab through tasks that ask participants to rate – and describe their ratings of – sounds on measures of valence and arousal.
 
Act, Avoid, and Approach
We often have to put in effort to avoid things that bother us, or to get things that we want. However, mood disorders such as depression and anxiety can shift how much we are willing and able to deploy this effort, in concert with changes in how we value avoiding aversive outcomes or approaching pleasant ones. With my co-supervisor Dr. Rebecca Todd, I investigate the factors that drive how people deploy physical and cognitive effort to avoid unpleasant outcomes or obtain rewards, and how participants’ levels of depressive and anxiety symptoms interact with their accuracy and effort deployment in a series of intermixed go/no-go and change detection tasks. Furthermore, I seek to identify and explore the cognitive processes that influence effort deployment in these tasks through mathematical and reinforcement learning models.
