Title: Fast periodic visual stimulation, a powerful paradigm to measure automatic numerical processing? 

Although humans can deal with various representations of numerical information (e.g., sets of dots, fingers configurations, Arabic digits, number words), it remains a challenging question to understand if and how the brain abstracts and integrates their common underlying magnitude information. To address this issue, we used a frequency-tagging electrophysiological paradigm called fast periodic visual stimulation (FPVS) with an oddball design, allowing to measure neural discrimination between two experimentally defined categories. This approach has become increasingly popular in the numerical cognition domain these past 5 years because of its elegant simplicity, objectivity, and very high signal-to-noise ratio. Several methodological factors and challenges, such as stimulus parameters, stimulation frequency or the instruction given to participants, will also be discussed.
