My research is concerned with the relations between stress, stress-related hormones and emotion regulation. Both the roles of early life stress (e.g. childhood maltreatment), as well as recent and acute stress are studied. With regard to hormones I focus on cortisol, known as ‘the stress hormone’, as well as on its supposed antithesis oxytocin, also known as ‘the love hormone’. We make use of pharmacological manipulations of these hormones, but also study genetic polymorphisms. The role of these factors in processing and regulating emotional information are studied mostly with experimental research in the lab. For example, I have used experimental paradigms that measure emotion recognition, empathy, attention to emotions and memory for emotional words and pictures. With this research I hope to give more insight into the underlying physiological processes that play a role in both healthy and disturbed emotion regulation, as well as the role of stressful circumstances on these processes.
