Contrast dependency and prior expectations in human speed perception
The perceived speed of moving objects has long been known to depend on image contrast. Lowering the contrast of first-order motion stimuli typically decreases perceived speed - the well-known "Thompson effect". It has been suggested that contrast-dependent biases are the result of optimal inference by the visual system, whereby unreliable sensory information is combined with prior beliefs. The ...
متن کاملSignal Integration in Human Visual Speed Perception.
Object motion in natural scenes results in visual stimuli with a rich and broad spatiotemporal frequency spectrum. While the question of how the visual system detects and senses motion energies at different spatial and temporal frequencies has been fairly well studied, it is unclear how the visual system integrates this information to form coherent percepts of object motion. We applied a combin...
متن کاملHow prior knowledge prepares perception: Prestimulus oscillations carry perceptual expectations and influence early visual responses
Perceptual experience results from a complex interplay of bottom-up input and prior knowledge or expectations about the world, yet the neural mechanisms by which prior knowledge biases incoming sensory information, as well as the precise stage of neural processing at which these two sources of information converge, is unclear. We investigated this issue by recording electroencephalography (EEG)...
متن کاملInvestigating specificity of experimentally induced prior expectations in motion perception
The brain uses sensory information that is often uncertain in order to efficiently generate perceptual representations of the world. This observation has led to the Bayesian brain hypothesis, in which the brain combines internal expectations of the world with unreliable external sensory information in a nearly optimal probabilistic manner. Recent studies have suggested that to be true in statis...
متن کاملConstraining a Bayesian Model of Human Visual Speed Perception
It has been demonstrated that basic aspects of human visual motion perception are qualitatively consistent with a Bayesian estimation framework, where the prior probability distribution on velocity favors slow speeds. Here, we present a refined probabilistic model that can account for the typical trial-to-trial variabilities observed in psychophysical speed perception experiments. We also show ...
