Decision Making & Discounting

Recently, I've started to change focus from perceptual decision making to more 'high level' decision making. This work focusses upon time- and probability-discounting. I'm started by building sophisticated Bayesian methods which we can apply to the study of how people trade off immediacy or certainty of a reward. More tools and empirical papers are in the works.

  • delay-discounting-analysis is a Bayesian analysis toolbox for delay discounting data. This toolbox aims to evolve into everything you need to analyse discounting experiment data.

Perceptual Decision Making & Attention

To what extent can we understand attention as a by-product of doing Bayesian inference about the state of the world? From this point of view, attention is not a 'thing' but a by-product of our perceptual decision making processes. See my two review papers for an introduction to this approach.
