Research summary

My research project focuses on  (the time structures of) intra-individual variability. Variability is a prominent characteristic of our behaviour as well as our central nervous system. For any repeated task we perform, the speed of every individual response will vary each time. Furthermore, some of our responses will be correct, while others may be wrong – even when the options are the exact same. It has been suggested that some part of the variability represents random, spontaneous fluctuations ('noise’), while another part of the variability can be explained by short and long term dependencies throughout the task. In my project, I examine what happens when people are given more control in a task, by allowing them to control the timing of the experiment the are taken part in.

Teaching summary

2015-2016: Practical Tutor
I deliver practical tutorials to first year BSc Psychology students, in which I teach them the basics of a good scientific report. By writing various scientific reports, the students learn to improve their scientific writing skills. My tasks include marking the reports and giving individual (written) as well as plenary feedback.
