OPENup: Optimizing exposure therapy for Posttraumatic Stress disorder
Although exposure therapy is the gold-standard treatment of posttraumatic stress-disorder (PTSD), only half of the patients adequately benefit from it. Based on recent insights into the mechanisms of extinction, this project examines strategies and techniques to improve exposure treatment outcome in…

Exposure therapy also helps patients with childhood trauma process the past
Childhood trauma can have a lifelong effect. Many therapists do not dare to confront these vulnerable patients with their past because they are concerned that the patients will be unable to cope. Research has now shown that exposure therapy can be helpful for this group of people.

‘Exposure therapy’ for bachelor students: preparing for the reality of scientific research
Already during their bachelor’s programme, students in Pharmaceutical Sciences are presented with challenging projects. One of these is the Bachelor Research Assignment (BOO in Dutch), which is often their first real experience with scientific research. This means a lot of responsibility and failures,…

Topologies: from field recording to phonography and the virtual
The insights leading to the present project firstly manifested themselves in 2008, when I worked with field recordings on the basis of relatively well-established notions in music composition studies, such as ‘musical material’ and écriture. With hindsight, I understand the outcomes of those first experiments…

Seeing voices: the role of multimodal cues in vocal learning
Humans and songbirds learn their vocalizations early in life by exposure to the vocalizations of adult conspecifics. Often, better learning outcomes are achieved with live, social, tutors than with audio-only exposure to vocalizations.
