Linking size perception to pRFs

Drs Christina Moutsiana and Benjamin de Haas published a study in Nature Communications in which we investigate perceptual biases for size judgements and their relationship to the spatial tuning of visual cortex (population receptive fields). We describe a model for how the visual system may infer object size from activation patterns in early visual areas. In this article we also present the our new psychophysical method for estimating perceptual biases across several visual field locations, Multiple Alternatives Perceptual Search (MAPS).
