Persoonlijk profiel


Healthy human task performance is characterized by significant differences between and within individuals. The dynamics in behaviour, underlying the richness of behavioural diversity, are largely undelineated. My line of research explicitly aims at enhancing our understanding of mechanisms underlying this variability in cognitive performance within and between individuals. 

Of specific importance is the comprehension of changes in the flexibility and limitations of the information processing system in the ageing human brain and how the dynamics in this system might be used to deal with cognitive task demands and to prevent age-related performance deteriorations.
The combination of measures of behaviour (reaction time and accuracy) and brain activity (e.g., EEG, ERP and fMRI) to examine task performance, forms a crucial aspect of this research. Especially, the simultaneous use of these non-invasive techniques provides particularly important ways to generate new information about brain dynamics in healthy individuals.

Research topics that I am working on at the moment include:
• Effects of healthy ageing on attention, working memory and reward processing
• Mental fatigue and task performance
• Gender differences and stress
• Sensory and liking of food
• Effects of caffeine on cognition
