How and why to perform Representational Similarity Analysis
A practical guide to representational geometry analyses using RSA
A practical introduction to RDMs, model comparison, dissimilarity measures and statistical inference.
These slides are a modest and certainly non-exhaustive introduction to Representational Similarity Analysis (RSA). They cover the logic of RDMs, model comparison, dissimilarity measures, statistical inference, and a few (more concrete) examples.
The final example uses behavioural similarity judgments and EEG data from our recent preprint on the representational geometry of durations: Grasso, Nalborczyk, & Van Wassenhove, 2026.
They were initially prepared for a lab tutorial, so the goal is not to provide a complete technical reference, but rather to make RSA feel a bit more intuitive.
