I am Gidon Frischkorn, an SNF Ambizione Fellow at the Cognitive Psychology Lab at the University of Zurich. I did my PhD at Heidelberg University under Dirk Hagemann, and was elected Fellow of the Psychonomic Society in 2024.
I work on measurement: on whether the things we measure in psychology track the cognitive processes they are supposed to. My research uses formal models to connect response times, accuracy, and choices to the processes that produced them, mostly in working memory, processing speed, and attention. For me, a statistical model is a formal statement about how a cognitive process works, and fitting it to data is a way of asking whether a theoretical idea is coherent.
The research page describes the four lines this work runs along, the software page the R packages that came out of it.
