Numerical cognition

My main interest is how humans understand quantities. What are the basic building blocks of symbolic number processing? How are multi-power numbers understood? How are negative numbers and zero processed? How are sets of objects quantified? How are these abilities impaired? Learn more about our findings on our Lab website at www.thenumberworks.org.

Data analysis

Our lab develops CogStat, an efficient and simple-to-use statistical software. Your results will be compiled automatically, the results will be displayed in APA format, and the test will be chosen and run automatically. Find more about this innovative software at www.cogstat.org.

Find me on Mastodon, Bluesky, X, ResearchGate, Google Scholar, Open Science Framework, GitHub, GitLab, ORCID, Scopus, Web of Science (previously Publons and Researcher ID).
