The paper investigates chromatic tuning in numerosity adaptation, finding that individual chromatic sensitivity correlates with the presence of multiple narrow chromatic channels.

This study investigates how the brain processes numerosity perception using EEG, finding that physical numerosity is encoded early, while symmetry-induced illusions emerge from later spatial grouping processes.

This study investigates how changes in stimulus features affect numerosity perception adaptation, finding that low-level feature changes, not novelty, reduce adaptation effects when changes are noticeable.

This paper shows that phasic pupil size changes occur along low-dimensional manifolds constrained by physiological substrates, providing a unified analytical framework for pupillometry.

The paper investigates pupil size as a biomarker for math anxiety and finds it correlates with performance but not directly with anxiety levels after accounting for performance.
