What is the representation underlying cognition? Formal models rely on multidimensional scaling of similarity judgments to derive the representation. In this preprint with @mdlbayes.bsky.social, we take an alternative approach; we build Bayesian generative models for three cognitive tasks. /1

The issue of defining the appropriate representation is core to the field of visual #workingmemory. Schurgin et al. (2020) introduced the TCC model and influentially argued that models of VWM should be in terms of psychological similarity, rather than in terms of the physical stimulus space. /2

Psychophysical scaling reveals a unified theory of visual memory strength - Nature Human Behaviour

Schurgin et al. propose a model of visual memory, arguing against a distinction between how many items are represented and how precisely they are represented, and in favour of a view based on continuo...
