Abstract

Perceptual biases vary considerably between individuals. In the framework of probabilistic perception, these variations are commonly attributed to differences in sensory noise, which determines reliance on internal priors, and thus perceptual biases. However, sensory noise is not the only determinant of perceptual outcomes: perceptual processes depend on beliefs about how stimuli are generated in the world. These beliefs, which can be conceived as generative models, play a decisive role. They are also mirrored in the types of explanatory models, static or iterative, offered in the literature. While static models assume that consecutive stimuli are independent, iterative models presume some temporal continuity. Here we compare experimental results for time and distance estimation with model predictions and propose that interindividual differences cannot be explained by individual levels of sensory noise alone, but that differences in biases such as central tendency and serial dependence are based on individual believes expressed by different generative models.Competing Interest StatementThe authors have declared no competing interest.
