Elkan Akyürek (Principal Investigator)

I obtained my PhD in 2005 from Leiden University, under the supervision of Bernhard Hommel. I was a postdoctoral research fellow at the University of Reading in the United Kingdom, and subsequently at the Ludwig Maximilian University Munich in Germany.

I returned to the Netherlands in 2009 to take up a faculty position at the University of Groningen, where I currently pursue a research program in perceptual and cognitive neuroscience.

I also act as Academic Editor for PLOS ONE, and as a Consulting Editor for the Journal of Experimental Psychology: Human Perception and Performance.


Aytaç Karabay

Aytaç completed his Bachelor degree in Psychology at Ankara University in Turkey, in 2011. After working as a psychologist in special education and rehabilitation centers for a while, he earned a full scholarship to continue his studies to obtain a Master degree in Experimental Psychology at the City University of New York in the United States, in 2015. He is now working on his PhD in Groningen.

Aytaç is interested in visual perception, specifically perceptual grouping, and in more cognitive processes such as temporal and spatial attention. He uses behavioral tasks, such as rapid serial visual presentation and visual search, to study how task performance is affected by stimulus features, and how physiological effects due to the consumption of substances, such as cocoa and caffeine, may alter perception and performance on these tasks.


Jefta Saija

Jefta obtained his Bachelor degree in Artificial Intelligence in 2010 and his Master degree in Human Machine Communication in 2012, both from the University of Groningen.

In his current PhD project, Jefta investigates possible links between the auditory and visual modalities, focusing specifically on temporal integration and phonemic restoration. His project is co-supervised by Deniz Baskent and Tjeerd Andringa.


Michael Wolff

Michael completed both his Bachelor degree in Psychology and his Master degree in Cognitive Neuroscience at the University of Groningen. During his Master and his current PhD he spent some time at the University of Oxford, where he initiated a close and ongoing research collaboration with Mark Stokes and his research group.

Michael’s research mainly involves working memory. He is interested in the neurophysiological mechanisms of the encoding, maintenance and retrieval of behaviorally relevant information and the role of attention in these processes. He utilizes electroencephalography and multivariate pattern analysis to explore the fast dynamics of working memory specific neural activity.
