Abstract

Theories of decision making propose that any single-stage decision can be represented as a process in which evidence is accumulated over time until it hits a decision threshold. The aim of this project was to develop memory and decision making tasks that were matched in perceptual stimuli and task difficulty such that we could test whether indeed the same or different neural mechanisms are involved in these two processes. We developed an experiment in which participants had to perform two tasks. The memory task was to remember two faces and judge whether a third face was the same; the perceptual task was to judge whether two tilted faces were the same. We showed that in both tasks, performance was around 80%. We also collected some preliminary EEG data.
