Cognitive enhancement reflects the use of any (legitimate) means such as for example food supplements to reach one’s personal best.

The HARVEST project explores the dietary choices that our hominin ancestors and relatives made, by recovering information on what they consumed, and how factors like environmental variation, intrinsic biology, and development of food processing technologies could have influenced their decisions.

This multidisciplinary minor addresses the fascinating question how we, modern humans, got to be the way we are. Who were our ancestors? How does our morphology, genetic makeup, brain and behaviour relate to that of other species? How does our evolutionary past affect our susceptibility to diseases?…

Cognitive psychology is the study of cognitive functions such as attention, memory, consciousness, emotion, language and action control. The goal is to understand the complex relationships between brain, mind and behavior.

Evolutionary and ecological interactions affect species on genetic and phenotypic levels. This theme aims to understand these processes at multiple levels: from molecules to genomes to populations and to communities. Our research focuses on evolutionary responses to anthropogenic change, the role of…

Avian Cognition describes the full range of avian cognitive abilities, the mechanisms behind such abilities and how they relate to the ecology of the species. Synthesising the latest research in avian cognition, a range of experts in the field provide first-hand insights into experimental procedures,…

Why do plants produces always produced so many slightly differing metabolites within a particular chemical class?

In this course, you will develop an understanding of evolutionary processes and their formative power. You will see how evolution has shaped biodiversity, and continuously influences our daily life.

One of the main research focuses of the Hortus botanicus Leiden is to study how the current biodiversity we see today, has originated, changed, and developed over time. The Hortus wants to study the relationship between species in specific focal taxa and see how they have diverged over time.

The Leiden Human Evolution Collective (LHEC) is a network of researchers from Leiden University, LUMC, and Naturalis with an interest in human evolution. The collective brings together existing expertise in Leiden to foster interdisciplinary collaboration in research, teaching, and public outreach.

In the specialisation Applied Cognitive Psychology, part of the Master in Psychology, you develop all the practical and academic skills necessary to apply psychological knowledge to real-life problems in working environments and organisations.

In the track Cognitive Neuroscience we focus on the investigation of the psychological, computational, and neuroscientific bases of human cognition by means of mind and brain research.

Reactions and reaction times in cognitive tasks.

Studies in Human Evolution is a series of the Faculty of Archaeology, Leiden University and The Max Planck Institute for Evolutionary Anthropology, Leipzig.

This interdisciplinary minor emphasizes the diversity and complementarity of various cognitive neuroscience approaches to understanding the human brain.

The project aims at highlighting and strengthening Dutch research into the diversity of the world’s languages from a historic and a cognitive perspective.

CERQ is a questionnaire measuring cognitive coping strategies developed by Dr. Nadia Garnefski and Dr. Vivian Kraaij.

What is the relationship between outcomes of dynamic testing and cognitive flexibility in young children?

Despite the field’s general agreement that pyrotechnology had a significant impact on the cultural evolution of humankind, our understanding of the origins and development of fire use and its role in humankind’s cultural evolution is very limited, blurred by strong disagreements over its chronology…

This doctoral thesis elaborates Langacker’s reference-point model by applying it to lexical semantics.

What is the role of the noradrenergic system in human cognition?

The Great Rift Valley in Africa is a real treasure trove for discovering early human fossils. The fossils found in this part of Africa have determined our view of human evolution. But was the Great Rift Valley really the place where evolution took place or just a place where fossils are well preserved…

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

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity.

Negotiation can only really be an alternative to warfare, if the parties agree on a framework of rules and procedures. And if the confidence of the partners may increase in another. But negotiations continue to wage war by peaceful means.

How do we experience electronic music? How does electronic music operate on perceptual, cognitive and affective levels? What are the common concepts activated in the listener’s mind when listening to electronic music? Why and how are these concepts activated?

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

In my research, I used a comparative wood anatomical approach to address wood evolution of the (largely) tropical flowering plant families Apocynaceae and Sapotaceae.

Sustainable energy from wind and solar is most readily available near the sea.

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.

How does stress influence cognitive performance? What is the role of selective attention to threatening information in this effect? Could we prevent stress-induced decline of cognitive performance with pharmacological interventions? Could we use resting state theta/beta ratio as a biomarker for cognitive…

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

Electrocatalysis allows for storing electricity or converting it into chemical bonds, producing chemical building blocks and fuels using renewable resources.

Can excessive worrying be reduced via stimulation of the vagus nerve?

On May 3rd, Varun de Castro Arrazola succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Varun on this great result.

On 1 April 2020, Marc Broekema defended his thesis 'Cognitive Bias in the Judgment of Business Valuations and Valuators'. The doctoral research was supervised by Prof. J.I. van der Rest.
