Jacobien van Peer


My name is Jacobien van Peer. I did my PhD (cum laude, December 2009) at Leiden University (NL), followed by a post-doc at the Swiss Center for Affective Sciences in Geneva (CH). Since 2012 I’m an Assistant Professor at the Institute of Psychology and the Behavioural Science Institute, Radboud University, and a research associate at the Donders Institute for Brain Cognition and Behaviour: Centre for Cognitive Neuroimaging.

My research focuses on motivational processes, specifically emotional information processing and action tendencies, and the neurobiological and brain mechanisms underlying these processes and their role in psychopathology and maladaptive behaviour. By combining EEG with behavioural assessments and hormone interventions in healthy and clinical samples, I and my co-workers have shown that the hormones cortisol and testosterone affect early processing of socially threatening information as well as approach and avoidance tendencies, which may play an important role in social anxiety. I also combined EEG with peripheral psychophysiological measures to investigate the role of appraisal processes in emotional responses. Currently I’m investigating emotional action control in threatening situations, and specifically how stress and fatigue affect performance under threat.
