Zsuzsika SjoerdsDr. Zsuzsika Sjoerds (Leiden University) is an assistant professor at the section Cognitive Psychology. In 2013 she obtained her PhD at the VU University, Amsterdam, studying habit formation and goal-directed control in alcohol dependence. That same summer she was visiting scientist at the Martinos Center for Biomedical Imaging, a collaboration between Harvard Medical School and Massachusetts Institute in Boston, USA, where she studied graph theoretical resting-state networks in alcohol dependent patients. During her Postdoc at the Max Planck Institute in Leipzig, Germany, she studied reinforcement-learning based decision-making and the influence of stress in several psychiatric disorders (addictive disorders, obsessive-compulsive disorder).
Now in Leiden she continues this line of research in healthy samples by studying decision-making processes and metacontrol states of persistent and flexible behavior. She applies computational modeling to entangle the neural mechanisms of these cognitive control processes with the use of (f)MRI. At the university she also teaches several bachelor and master courses in the field of cognitive neuroscience and decision-making, and coordinates the Minor Brain Cognition.



Dr. Guido Band (Leiden University) is an associate professor in psychophysiology and cognitive psychology. He has studied various aspects of cognitive control, such as dual-task performance, flexibility and inhibition. Cognitive control is often the limiting factor in complex performance as it suffers from the effects of sleep loss, old age, stress, and intoxication. Band is interested both in identifying the consequences of reduced control for real-life performance, such as navigation and speeded decision making, and in techniques that are promising in enhancing cognitive control such as game training and simulation. Band has set up the EEG laboratories of Leiden University and has coordinated the master program “Applied Cognitive Psychology”, for which he collaborates with most of the traffic institutes in the Netherlands, which are also represented at the symposium.

Friederike BehrensFriederike Behrens (Leiden University) is a PhD candidate at the cognitive psychology department. In her project she investigates how people communicate and influence each other’s emotions and intentions by mimicking each other’s psychophysiological responses in close interactions. Here, she addresses a wide range of responses including heart-rate measures, skin conductance response, and pupil dilation in real-life interaction settings. A particular interest of Behrens is to gain a deeper understanding in the statistics involved in analyzing (these) complex experimental data. Next to her PhD project, she is a member of the board of NVP and the PhD council of the Faculty of Social and Behavioural Science at Leiden University.



We’d like to give our special thanks to the sponsor NVP (De Nederlandse Vereniging voor Psychonomie) and co-sponsor EPOS (Graduate Education Network) making this symposium possible.
