When we are in a conversation, how do we know exactly when to respond, and how do we manage to respond so swiftly, yet without interrupting our interlocutors? Can speech melody – in particular utterance final “boundary tones” – help us determine who will speak next, or are these cues too late in the…

Does the public speaking anxiety that many youngsters experience originates from specific characteristics in their earlier development?

In this project, we aim to develop mathematical models to mechanistically and quantitatively predict the dynamics of cellular stress pathway activation and its relation with toxic effects when cells are exposed to various toxicants.

The linguistic project constitutes the connection between the two other subprojects. It consists of two parts.

What is the role of technology and cyberculture in Korean social structures and in the potential formation of a new collective subjectivity? How do we reorient disoriented souls?

This project investigates properties of quantity expressions across languages from the perspective of how quantity is represented in the human brain.

Increasing above- and belowground biodiversity in arable leek cultivation to stimulate pest control by natural enemies.

This thesis, conducted in the framework of ERC Starting grant project BABYLON (PI: Caroline Waerzeggers), presents an investigation into Babylonian society, focusing on the city of Borsippa during Neo-Babylonian and early Persian rule (c. 620-484 BCE).

What is the relation between brain development and social and cognitive development across childhood, adolescence and adulthood?

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

The research group Corporate Governance and Strategy investigates how, with whom and for whom a firm/corporation creates/captures value, in order to inform practice and rule makers about governance issues. By focusing on the dual character of the firm as an entity by itself but also consisting of stakeholders,…

We investigate water quality and want to understand the effects of human interference on aquatic biodiversity.

The Leiden Index of Depression Sensitivity (LEIDS) measures cognitive reactivity (CR) to sadness, an aspect of cognitive vulnerability to depression, conceptually similar to rumination.

Can positive peer feedback break the cycle of negative self-relevant cognitive processes and reduce self-reported anxiety in early adolescents?

SALTSWAT -- a project which combines the Spaces for Active Learning & Teaching and the Support wtih Active Teaching -- began in Mid-2019 and is running in pilot until the summer of 2020. The purpose of the project is to find answers to the question of how to systematically accelerate 'active teaching…

Do natural soundscapes affect migratory decisions of fishes moving up and down rivers and is this process disturbed by vessel sounds?

This research area is focused on the development and application of novel concepts and models in the emerging area of quantitative systems pharmacology (QSP).

How do dissociative states affect the ability to suppress emotional distraction (in the context of a working memory task) in patients with Borderline Personality Disorder?

We aim to conduct as few animal experiments as possible. We are continually exploring methods to Replace, Reduce, and Refine animal experiments, commonly referred to as the three Rs. Additionally, we assess each study to ensure the implementation of the 3Rs has been maximised. The Animal Welfare Body…

Addressing Global Challenges through International Scientific Consortia

LEGITIMULT examines how Covid-19 measures by governments impact multilevel governance and democratic governance in 31 European countries

In this research project child language phonology is studied from the perspective of a psycholinguistic speech-production model and this model is in turn studied from the perspective of developmental phonology.

The NET-ROL project builds on the EU's definition of the rule of law to investigate the role of networks in law-making, executive decision-making, and the judiciary. It examines how these networks influence the weakening of the rule of law. Through an interdisciplinary perspective, the project explores…

Growing public backlash against international organizations (IOs) and attacks of national political elites on the rule of law increasingly challenge governance by IOs.
