Psycho-physiological studies for health and disease.

Speech Prosody is the biennial meeting of the Speech Prosody Special Interest Group (SProSIG) of the International Speech Communication Association (ISCA).

Deepfakes are videos that have been manipulated to replace one person’s likeness with that of another. They can be difficult to distinguish from authentic videos.

Our research is done at two different locations.

The aim of this research is the systematic analysis of the wisdom coined by Nahua people of Mexico, based on the historical sources and archaeological evidence, but also in the knowledge developed by contemporary indigenous communities and the contributions of indigenous scholars.

Researchers have been working for centuries in mapping the human brain. But in the year 2017 some brain structures remain still not well mapped, especially those located at the brainstem. In this paper, we quantified the test–retest reliability of imaging the brainstem nucleus locus coeruleus in vivo…

Leiden University Centre for Linguistics (LUCL) is a reputable institute in the field of linguistics, offering excellent research and education opportunities covering a broad range of languages of the world.

Drawing is one of the most unique human behaviours. Like language, drawing is a mode of communication and a cognitive tool that from an early age allows us to interact with others. Is the early development of drawing skill influenced by the social environment? If so, how?

Health is a wonderful gift, both for humans and for society. If we are able to prevent both physical and mental illnesses, we can spare a lot of suffering and fight rising health costs. Social scientists and physicians in Leiden are working closely together to conduct research on the human mental, behavioural…

Human AI is where artificial intelligence and machine learning meet philosophy, cognitive science, and the creative arts. Examples of research questions in this domain are: 'Can an algorithm be creative by human standards?', 'Can creative processes, such as composing music or writing poetry, be modelled?',…

If we want to build robots and computer systems that are not only smarter but also possess more social skills, we first need to find out more about how humans interpret information. Max van Duijn and Tessa Verhoef conduct research at the intersection of cognitive science and AI.

Some examples of AI-research done at Leiden.

Fundamental research teaches us how our brain decides to eat one more sweet, instead of doing exercise. A public information campaign about healthy lifestyle has little impact on the decision, as Professor of General Psychology Bernard Hommel is aware. However, he does know what works. But the question…

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…

Adoptees in the Netherlands generally do not use more medication than their non-adopted peers.

Researchers at Leiden study group behaviour. One of their findings is that when people make sacrifices for another member of their group, it is probably instinctive. Insights of this kind enable us to better understand and influence the social processes in a neighbourhood or company.

This project seeks to integrate scientific research and practical knowledge in the study of the mechanisms that make dialogue an effective tool for communication, teaching, and thinking.

Researchers of the National University of Singapore and Leiden University have discovered that chimpanzees and bonobos share the contrasting colour pattern seen in human eyes, which makes it easy for them to detect the direction of someone’s gaze from a distance.

Knowledge and culture subproject 2:

What are the most important perpetuating factors of chronic fatigue and chronic fatigue syndrome, and which interventions are effective in influencing these factors?

Together with researchers from over the world, the ENIGMA-Anxiety Working Group endeavors to unravel the neurobiology of anxiety disorders and related constructs.

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

In the face of threats from other groups, humans, chimpanzees, and a selection of other species get closer with their own. This research shows that even bonobos show a moderated version of this effect. This suggests that this behavior may emerged prior to the Pan-Homo split, several millions years ago.…

The research programme Formal Theoretical and Experimental Linguistics brings together LUCL researchers who focus mainly on formal theoretical and experimental linguistics.
