I will review a simple neurocomputational model of choice, and show that it can account for individual difference in how people integrate information for choice. I will then show that non-linearities and lateral-inhibition privide a mechanism that can optimise choice performance, in choice between multiple-alternatives. Finally, I will show how this model can be extended to value-based decisions, accounting for preference-reversals and a number of violations of `normativity'.
