Research project

To overcome situations with conflicting information we need to exert cognitive control. We can do this transiently, by adapting to the situation immediately after conflict detection, in which case cognitive control operates on a short time scale. Or, we can prepare ourselves for future conflict and keep a sustained control mode operating on a long time scale. Using behavioral modeling and neuroimaging techniques, I study how we can quantify the time scale of control and what factors affect differences in control mode. For example, how is the time scale of control affected by attentional load? Can a long time scale be maintained when information is processed unconsciously? And what neural processes correlate to time scale differences?
