We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

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).…

In the future, physicians may be able to identify dementia much earlier than they can today because a computer algorithm will be able to predict from brain scans how our memory is going to develop.

Psycholinguistic research

On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

Leiden University Centre for Linguistics (LUCL) has a longstanding tradition in research in the world’s languages and features unique linguistic expertise.

A research into how people eat and drink during their daily routines, and the circumstances under which these activities take place.

This project investigates which metaphors are problematic in machine translation, when, why, and for whom.

The Developmental Psychology specialisation of the Research Master’s in Psychology offers a strong theoretical background to provide the varied knowledge-base needed for a thorough understanding of emotional and cognitive development across childhood and adolescence.

What is emotion in human and nonhuman animals? How do emotions get to expression and how do they impact on our interactions, our decisions to trust, distrust or cooperate? Why do we mimic and synchronise affective processes?

Three Leiden astronomers have shown that some asteroids that are considered harmless for now, can collide with Earth in the future. They did their research with the help of an artificial neural network. The results have been accepted for publication in the journal Astronomy & Astrophysics.

Learning how computers can process and describe images just like human beings do.
