From ca. 1540 to 1600, thousands fled the war-stricken Southern Low Countries to the British Isles, Germany, and the Northern Low Countries. Research on this displacement crisis, central to the formation of the Netherlands and Belgium, reflects 21st-century debates on migration and language: language…

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

In science, it is of vital importance that multiple studies corroborate the same result. Researchers therefore need to know all the details of previous experiments in order to implement the procedures as exactly as possible. However, this is becoming a major problem in neuroscience, as animal studies…

How has early development in R. ocellatus been modified as a result of its parasitic embryonic lifestyle?

What are the biological effects of Chinese herbal medicine in regulation of cancer cell metastasis?

Below are resources which provide a short primer on the subject of active learning.

The focus of the Bachelor Data Science & Artificial Intelligence is on computer science, and its applications in Artificial Intelligence. You will receive a strong basis in mathematics, statistics and computer science, combined with advanced knowledge of machine learning, cognitive science, human-robot…

In the specialisation Economic and Consumer Psychology, part of the Master in Psychology, you will study the psychological mechanisms that underlie our decisions and choices concerning consumption and other economic behaviours.

This is a Special Issue of the peer-reviewed journal 'Social Sciences and Missions', which provides a forum for exploration of the social and political influence of Christian missions worldwide.

How do we explain the fact that certain areas had many large cities, while other areas were studded with large numbers of small towns and yet other areas had very few urban agglomerations of any kind?

SOLID: Solidarity under strain - A legal, criminological and economic analysis of welfare states and free movement in the EU. Analysing the ways in which immigration structurally challenges and changes the organization and conceptual boundaries of national welfare states.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Can playing certain games decrease cognitive decline or even enhance cognitive performance in the aging population?

The Center for Interdisciplinary Placebo Studies Leiden (IPS) aims to advance the understanding of placebo and nocebo effects, their underlying mechanisms, and their potential applications in clinical practice. IPS consists of a group of interdisciplinary researchers working at Leiden University with…
