Background

poster prize

I have a background in both cognitive psychology/neuroscience and educational research. I studied psychology in The Netherlands (Groningen) and Germany (Munich). I have worked many years in the USA in the field of neuroscience (single-neuron recording). After that, I came to the UK, where I have worked both in Scotland and England.

My current work focuses mainly on educational psychology and applied educational work.

I am particularly interested in gender differences how boys and girls learn and achieve, and how gender differences are expressed in adults. I have written quite a few articles about this topic.

Apart from that, I am also the creator of PsyToolkit, a popular online research and online learning toolkit (mainly for cognitive psychology and individual differences research). My article about PsyToolkit is the most cited article in Teaching of Psycholgy.

Much of my past and present research has been funded with grants from the ESRC, NIH, German Science Foundation (DFG), Max-Planck-Society, James S. McDonnell Foundation, British Academy, and Nuffield Foundation. In the publication section, you can find a variety of articles that resulted from these grants.

One of the projects I am interested in is related to sustained attention (cognition) in school children. Our PhD student JingJing Yang (杨晶晶) was awarded the best poster prize for her work on this project at the annual conference of the British Psychological Society Educational Psychology Section in Oxford (see picture).

This paper looked into a popular belief about women and multitasking and was widely covered, for example on the BBC. It is important to point out that now we know that there are different studies on this topic, and it seems that the specific type of task being used plays a role; others have not found the effect using different a different task.

This is the first study that shows that monkeys, who can perform a cognitive task-switching paradigm really well after lots of training, have specific neurons that encode which current task they can do. This article was the result of years of work on trainig monkeys and recording from neurons in lab settings. One of the hardest studies I have ever done, but the insights were a real novelty and were written about by others.

Software

psytoolkit

PsyToolkit is an online platform for running cognitive psychological experiments and/or online surveys. On the right, you see the PsyToolkit logo.

PsyToolkit runs in a browser. PsyToolkit can do everything other software of this type can do, but it is free to use for non-profit researchers and students. It is ideal for presenting both survey questions and cognitive reaction time experiments. It has its own domain-specific scripting language and comes with lots of demonstration experiments and psychometric scales.

It received funding from, among others, the UK ESRC research council. Click here to find out more.

Name pronunciation

holland

My name is Dutch and difficult to pronounce for English speakers. If you are curious how to say my name listen to me saying my name. It is not easy unless you are Dutch, Afrikaans, Hebrew or Arab speaking. Not that my name exists in the latter two languages, but somehow native speakers of those languages seem to manage pronouncing my name really well. If you find it too challenging, feel free to use the English equivalent Gilbert. There are also equivalents in Italian, Spanish, and Portugese (Gilberto), French, as well as German and Nordic languages (Gisbert).
