Unconstrained day-to-day activities are difficult to quantify and how the corresponding movements shape the brain remain unclear. Here, we recorded all touchscreen smartphone interactions at a sub-second precision and show that the unconstrained day-to-day behavior captured on the phone reflects in…

Are there any differences in gaze behavior between high and low socially anxious individuals? What factors influence the relation between social anxiety and gaze behavior?

The research of the group Learning and Behavior Problems in Education addresses learning difficulties in the areas of reading (technical reading and reading comprehension) math and writing, and examines learning-related behaviors behaviors.

To what extent and how do identity processes influence health behavior?

The Learning and Behavior Problems in Education program group is responsible for teaching in the area of learning problems.

Recent studies of Neandertal body mass and skin surface indicate raised energetic requirements in this lineage compared to anatomically modern humans.

Governing Cyberspace: Behavior, Power and Diplomacy is based on a selection of papers presented during The Hague Program for Cyber Norms' inaugural conference Novel Horizons: Responsible Behaviour in Cyberspace from 5-7 November 2018 in The Hague. The volume is edited by Dennis Broeders and Bibi van…

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

Social relationships of students are important. Especially for students with problem behavior. How can a teacher support students in their social relationships via their own interactions with students? A lot, as is shown by a meta-analyses of Hinke Endedijk. She assessed almost 300 studies about teacher-student…

The program group Learning and Behavior Problems in Education: Challenges and Solutions strive to find solutions to the learning and behavior challenges faced by preschool and elementary-school children, youth, and young adults in education. In doing so, the group focuses on cognition and behavior and…

Which educational and child welfare interventions offer optimal opportunities for positive development to children with severe behavioral and emotional disorders.

The program group Learning and Behavior Problems in Education is located in the Faculty of Social and Behavioural Sciences of Leiden University near Central Station.

This paper describes the development process of voting behavior in Chile; particularly the relationship between the class voting theory and the theory of cultural post-materialist vote is investigated. This research deals with Chile as a case study, a developing country with a relatively stable democracy…

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

The major aim is to develop, evaluate, and implement disease-generic cognitive-behavioral interventions through the internet in order to optimize tailored health care for patients with chronic somatic conditions.

The company QuantActions promises that through capturing and analysing the data of smartphones it will be able to “detect important indicators related to mental/neurological health”. Neuroscientist Arko Ghosh is the company’s cofounder and talks in The Guardian about tappigraphy patterns.

Although smartphones and other consumer cameras are increasingly used for scientific applications like citizen science, it’s still difficult to compare and combine data from different devices. PhD student Olivier Burggraaff developed a new easy-to-use standardised method which makes it possible for…

The lipid matrix in the stratum corneum (SC), the upper layer of the skin, plays a critical role in the skin barrier. The matrix consists of ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs).

On July 5th, Mulugeta Tarekegne Tsegaye succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Mulugeta on this great result.

N-acylethanolamines (NAEs), which include the endocannabinoid anandamide, represent an important family of signaling lipids in the brain. The lack of chemical probes that modulate NAE biosynthesis in living systems hamper the understanding of the biological role of these lipids.

Theoretical physicists research a special class of particles; Weyl fermions. They have found them to exhibit paradoxical behavior, in contradiction to a thirty-year old fundamental theory in electromagnetism. A possible application is a new kind of electronics—spintronics. Publication in Physical Review…
