A new methodology for network studies

Network approaches are undergoing a revolutionary advance in the field of psychology. Whereas explanations for cognitive development and mental problems have long been sought in the brain, the focus now increasingly lies on the interaction between observable factors. In the case of depression, for example, we no longer look for a single cause but consider the interplay of symptoms such as insomnia, depressed mood and concentration problems. However, scientist Maarten Marsman says, the methodology used by network studies is in need of improvement. He has received an ERC Starting Grant to develop new methodology. Maarten Marsman, assistant professor in psychological methodology at the University of Amsterdam, says that a network approach to explain our cognitive development and mental problems is becoming increasingly common in the social sciences. 'For a long time, for example, it was thought that our personality and intelligence - as well as mental problems such as depression - were found somewhere in our brain.
