Social anxiety runs in families, but the neurobiology underlying this genetic vulnerability is until now largely unknown. The unique Leiden Family Lab study on Social Anxiety Disorder (LFLSAD) aims to broaden our knowledge with respect to this genetic susceptibility.

Persistent somatic symptoms are long term symptoms that lack a clear medical explanation. These symptoms have a high prevalence where most people know someone who experiences such symptoms or they experience such symptoms themselves. Symptoms can vary greatly in and between people. While one person…

Basketry, cordage and textiles made of plant fibers or bark are rarely preserved in the archaeological record. By means of experimental archaeology and microwear analysis, we obtain indirect evidence about this important craft.

The group of Dr. Roxanne Kieltyka designs and synthesizes molecules that self-assemble into polymeric materials using specific non-covalent interactions. These substrates can be used for numerous applications in medicine ranging from disease detection to cell delivery depending on the (bio)molecular…

How can a participatory theatre-based pedagogy support pre-service teachers in The Netherlands in developing critical awareness and an active change-agent identity with respect to diversity, equity and inclusion in educational contexts?

All languages use melody in speech, primarily via rises and falls of the pitch of voice. Such pitch variation is pervasive, offering a wide spectrum of nuance to sentences – an additional layer of meaning. For example, saying “yes” with a rising pitch implies a question (rather than an affirmation).…

This study investigates and analyses didactical approaches in theory and practice of both scholars and expert teachers in Religious Education/Life World Orientation (for secondary level) in their role as Identity Agents in order to discover and develop didactical key components contributing to religious…

How is the development of physiological responses to social evaluation in adolescence affected by other normative developments, such as pubertal, socio-cognitive and psychosocial development? Are social anxiety and public speaking anxiety associated with characteristic patterns of stress responses…

The ultimate aim of this project (initated by the European Law Institute) is to design a framework that will enable the further development of coherent and functional rules for business rescue in Europe.

The Botany Laboratory is part of the Faculty of Archaeology, University of Leiden. Under the supervision of Dr Mike Field, research is carried out here on archaeo- and palaeo-botanical material including seeds and fruits, pollen and spores, and wood.

The effects of many treatments are determined, to a significant degree, by factors other than the medicine or treatment itself. For example, placebo effects can be equal to the effect size of for example antidepressants or painkillers. Contributing factors are the trust placed in the doctor, the expectation…

Many metalloenzymes that are key to bioenergetics are membrane enzymes, with canonical examples the complexes I, II, III and IV in the mitochondrial inner membrane. To study these enzymes in a native-like lipid membrane environment, we aim to develop novel bioelectrochemical techniques.

When do fire making tools appear in prehistory, and how might the use of these tools manifest in the archaeological record?

docARTES is a doctoral programme for performers and composers. It offers a unique environment for critical reflection on musical practice.

It has been argued that the Internet presents numerous new opportunities for crime, including homicide. So far, empirical scholarly research in this domain is rather limited. In order to discover how perpetrators have used the Internet in the homicides they have committed, we conducted an international…

Grammatical gender is famously the most puzzling of the grammatical categories. We have a solid typology of gender systems, yet exciting and unexpected patterns keep turning up which defy easy classification and straightforward analysis. Some of these question, stretch or threaten to cross the outer…

Larissa Mendoza Straffon and colleagues investigated visual attentional biases toward self-made artworks, which tend to be favoured, remembered, valued, and ranked above and beyond objects that are not related to the self. Their findings confirm that attention and preference are higher for self-made…
