Sabrina Hansmann Roth
Ingénieure de recherche - Visual perception, psychophysics
I am a vision scientist and my research focusses on human visual perception using behavioural methods and computational modelling. In particular, I am interested in the mechanisms used to represent information in visual memory. For that, I investigate probabilistic representations of visual ensembles, visual priming and perceptual biases such as serial dependence.
I am currently a Postdoc at the SCALab working with Bilge Sayim on spatial perception using appearance-based methods (in collaboration with Wolf Harmening at the University of Bonn, Germany) and some projects on the role of perceptual grouping in ensemble perception.
